Abstract
In developed countries, the years from age 30 to 45 are for many the most intense,
demanding, and rewarding years of adult life. During this period of the lifespan most adults must
negotiate the intersecting demands of progressing in a chosen career, maintaining an intimate
partnership, and caring for children. Successes or difficulties in meeting these simultaneous
demands have the potential to profoundly influence the direction of a person’s adult life. As
such, we believe that it is of critical importance to better understand this developmental period
that we call established adulthood. This paper provides a new theoretical conceptualization of
established adulthood, outlining its distinctiveness from emerging adulthood and midlife in terms
of physical health, well-being, cognitive development, and the Career-and-Care-Crunch of
competing work and family responsibilities. We also consider variations in the timing and
experience of established adulthood, including variations by gender and social class, and provide
suggestions for future research. As economic and social arrangements continue to evolve, so too
will this developmental period, providing fertile ground for developmental theory and research.

Established Adulthood: A New Conception of Ages 30 to 45
Over the past several decades, psychological theory and research has made substantial
progress in charting most segments of the adult lifespan. The theory of emerging adulthood
focused on how the years from age 18 to 29 have changed across developed countries and
conceptualized these years as a new life stage (Arnett, 2000; 2015). The landmark MIDUS
longitudinal study explored features of midlife in the United States and in Japan, generating new
interest in the distinctive characteristics of ages 45 to 65 (Brim, Ryff, & Kessler, 2004; Ryff,
Kitayam, Karasawa, Markus, Kawakami, & Coe, 2008), and theoretical work has highlighted
midlife as a crossroads between growth and decline (Lachman, Tesshale, & Agrigoroaei, 2015).
Finally, worldwide societal recognition of the consequences of steadily increasing longevity has
led to growing theoretical and research attention to the later years of adulthood (Kunkel, Brown,
& Whittington, 2014).
Despite an increased focus on adulthood in psychological science, one period of the adult
lifespan has been largely overlooked. This is the period from age 30 to 45, when most people are
deeply absorbed in career development while fulfilling the responsibilities of an intimate
partnership and caring for children. Although there is abundant research on key aspects of this
developmental phase, including career development, marital satisfaction, divorce, and parenting,
these aspects of development have not been integrated into a compelling developmental theory.
Hence, the purpose of this paper is to provide a new conceptualization of the years from roughly
age 30 to 45. We propose to call this developmental period established adulthood.
There are a number of reasons why a comprehensive developmental theory of established
adulthood is needed. First, there is no current common nomenclature for this period of the
lifespan. It is sometimes referred to as part of “young adulthood,” but that term has been applied
as young as age 18 and as old as age 45 (Arnett, 2015). It is sometimes referred to as part of
“middle adulthood,” but midlife theory and research more often focuses on ages 40 or 45 to 60
and can extend as high as age 65 (Lachman, 2004; Lachman et al., 2015). Without an agreed
upon term for the period after emerging adulthood but before midlife, it is hard to compile the
research base necessary to gain a comprehensive understanding of it. Second, we believe that it
is imperative to build a developmental theory of this period because the years from 30 to 45 are
often the most intense and demanding years of adult life in developed countries, when
obligations are high in both work and family domains. Moreover, successes or difficulties in
handling the intensity of the intersection of these developmental tasks has the potential to
influence profoundly the rest of a person’s adult life. Consequently, a better understanding of this
developmental period has implications for supporting established adults through policy or
therapeutic interventions, as they navigate what has been described as the “rush hour of life”
(Knecht & Freund, 2016).
In proposing the concept of established adulthood, we first examine its theoretical place
in the lifespan. We then examine how established adulthood is distinct from emerging adulthood
and midlife in terms of physical health, well-being, and cognitive development. Next, we focus
on the intersection of work and family responsibilities during ages 30 to 45 as the central
developmental challenge of these years. We then consider variations in the timing and experience
of established adulthood, including variations by gender, ethnicity, and socioeconomic status, as
well as other variations, such as having children early or remaining single without children.
Finally, in the last section of the paper, we propose some initial research questions.
From the outset, it should be noted that due to space limitations we are unable to describe
all aspects of this new conceptualization of ages 30 to 45, and we focus mainly on developed
countries. Space limitations have also led us to focus on salient developmental tasks. As
development is dynamic and not static, it is important to remember that these tasks represent
developmental processes. For example, becoming a parent is not a single life event, but an
ongoing developmental process during which identity, behavior, and interactions with a person’s
immediate (e.g. the workplace) and distal (e.g. larger social structures) contexts evolve. We are
also limited to building our theory by reviewing extant research that, like most psychological
research, has been conducted mainly with samples that are predominantly White, middle class,
and Western (Arnett, 2008). Race, ethnicity, gender, social class, and cultural context are likely
to be hugely influential in people’s experiences of established adulthood and should be a focus of
research in the new field.
Phase, Period, Conception, or Life Stage?
Is established adulthood a phase, period, conception, or life stage? For decades there has
been a lively debate in developmental psychology over the usefulness of life stage concepts
(Arnett, 2016; Elder & Shanahan, 2006). Until this debate was initiated in the 1980s, psychology
had a long and unfortunate history of proposing universal life stage theories based on a tiny
segment of the human population. Critics rightly called the assumptions of those theories into
question. We hope that psychology has now decisively moved beyond universal assumptions and
that there is widespread recognition that the historical and cultural context of human
development is of crucial importance across the lifespan (Jensen, 2015). We are certainly not
proposing established adulthood as a universal, one-size-fits-all theory. We acknowledge that
many may not experience established adulthood as we outline it here. Rather, we are proposing
established adulthood as a potentially useful heuristic for conceptualizing a fascinating and
important period of adult development that has either been neglected or combined with other
periods of the lifespan in developmental research.
We view life stage concepts as cultural constructions that provide a useful map of
culturally-expected developmental risks and challenges in each portion of the lifespan (Arnett,
2016). Developmental change in adulthood is continuous rather than separated into phases, and
does not occur within strict time frames as it does in childhood and adolescence (Hooker, 2015;
Hoare, 2006). This is because during adulthood sociocultural processes have a greater influence
on development than biological processes or institutional structures such as schools (Baltes 1987;
Hooker 2015). This means that variations in our contexts, experiences, life choices, and social
roles lead us to become more, not less, heterogenous as we age (Hoare, 2006). Consequently, the
age range of 30 to 45 for the period of established adulthood is approximate, and is likely to vary
by race, ethnicity, socioeconomic status (SES), culture, country, developmental contexts,
individual choices, and historical context. These factors are also likely to influence people’s
experience of established adulthood. While we outline here some of the developmental tasks and
concerns that we believe are salient for those in this age period, we acknowledge that these tasks
will not be relevant to all groups of people. Specifically, not all people will experience the
normative route through established adulthood as we outline it here. We hope that researchers
will investigate this period of development to document its many variations.
It should also be noted that the specific term “life stage” has a long history in
developmental psychology, usually denoting qualitative change from one stage to another, for
example from concrete to formal operations in Piagetian theory. That is not how we are using
“life stage” here; we see life stages simply as conceptual frameworks that may or may not entail
qualitative change but are useful ways of delineating the main developmental issues and
challenges of each phase of life. However, for those who prefer a more restrictive use of “life
stage,” established adulthood might not meet the requirements to be a developmental stage and
may thus be better viewed as a phase of adult development.
In this spirit, and with these caveats, we believe that proposing established adulthood as a
new concept has the potential to clarify the developmental issues and processes prominent during
the years 30 to 45 and draw together the large but disconnected body of research that has focused
on topics such as parenting young children, career development, and work-family balance. We
also hope that proposing this new life stage concept will inspire research focused specifically on
the experiences of those aged 30-45. Our model is the theory of emerging adulthood, which
drew together existing literature on topics such as the school-to-work transition and leaving the
parental home and has inspired thousands of studies on ages 18-29 since it was proposed 20
years ago (Arnett, 2000). We hope that proposing an integrated developmental conception of
established adulthood will have a comparable effect of inspiring research on development at ages
30 to 45.
Distinction Between Emerging and Established Adulthood
Although an adult life phase of family formation and career development was recognized
by early developmental theorists such as Havighurst (1953) and Levinson (Levinson et al.,
1978), a number of important demographic changes have taken place over the past half century
that have shaped the current structure of established adulthood, making it demographically
distinct from emerging adulthood and situating it roughly in the age period of 30 to 45. In
developed countries, work and family life transitions that historically took place when people
first reached their twenties are now typically taking place when people reach their thirties
(Arnett, 2015). Across developed countries, more people are obtaining tertiary education or
training well into their twenties, and finishing education is typically followed not by entry into a
stable long-term job but by years of frequent job changes with commitment to a career not
occurring until the thirties. For example, in the United States the median number of job changes
from age 18 to 29 is ten, a far higher number than in any subsequent decade (Bureau of Labor
Statistics, 2019a; U.S. Department of Labor, 2012). Additionally, in contrast to the high rates of
unemployment in the twenties, by age 30 unemployment falls to a stable rate maintained through
the forties and fifties, across developed countries (OECD, 2019a). In sum, in contrast to the
exploration, information gathering, and career preparation that typically takes place during
emerging adulthood, established adults tend to commit to an occupational path that includes
gaining greater expertise, taking on greater responsibilities, and moving up in an organizational
hierarchy (Day, Harrison, & Halpin, 2012).
While this pattern of career development is common, it is important to note that there are
likely to be exceptions based on race, ethnicity, gender, and social class. Longstanding structural
and systemic racism across Western countries often impedes the career development of people of
color (APA 2007). For example, in the United States people of color are disproportionately
unemployed, underemployed, and in precarious, low paying jobs (Bureau of Labor Statistics,
2011; 2019b). This means that during established adulthood, while most of their White
counterparts are enjoying stability and advancement in their careers, people of color may
continue to experience career instability and stagnation (Doede, 2016).
In the family domain as well, there has been a normative upward age shift toward
commitment and stability occurring around age 30. Across developed countries the median age
of first marriage is higher than ever before, around age 30 for women and 32 for men (OECD,
2019b). Most developing countries are trending in the same direction. Similar shifts have taken
place internationally in the median age of first childbirth, which is also now around 30 for
women in developed countries and is rising in developing countries (OECD, 2019c). Between
2000 and 2014, the proportion of first births to women in developed countries aged 30–34 rose
28% and first births to women aged 35 and over rose 23%, whereas births among younger
women declined (OECD Family Database, 2018).
In the family as in the work domain, demands are likely to vary by race, ethnicity, and
socioeconomic background. For instance, Latinx and African American women have lower
median ages of first childbirth than Whites and Asian Americans (Matthews & Hamilton, 2016),
and are more likely to be single mothers (Hummer & Hamilton, 2010). The stresses of
established adulthood may therefore be compounded in these groups.
Distinction Between Established Adulthood and Midlife
In contrast to the early theories of Havighurst (1953) and Levinson (Levinson et al.,
1978), little modern theory has distinguished between established adulthood and midlife. Instead,
the years of “middle adulthood” have been often stretched to extend from as low as age 30 to as
high as age 65 (Lachman, 2004; Lachman et al., 2015). However, we believe that range is too
large to be developmentally meaningful and that it is more coherent and compelling to
distinguish established adulthood (roughly ages 30-45) from middle adulthood (roughly ages 45-
65).
Established adulthood is developmentally distinct from midlife in a number of ways.
Established adults are typically gaining expertise in their chosen field and seeking to rise in their
work status and achievements, whereas most midlife adults have reached the peak of their career
arc (Riza, Ganzach, & Liu, 2016). Established adults often have young children who are living at
home and a large part of their daily lives is devoted to caring for those children. In contrast,
adults at midlife more often have older children, who have left the family home or, if still at
home, require less physically demanding care from parents. Midlife adults are also more likely
than established adults to experience age-related physiological changes, such as menopause for
women and andropause for men.
Notable Features of Established Adulthood
Like other developmental phases, established adulthood has distinctive features that are
more prominent during this period than during other periods of life. Table 1 summarizes a range
of distinctive features of established adulthood as compared to emerging adulthood and midlife.
Below, to illustrate the utility of viewing established adulthood as a separate phase of the adult
lifespan, we briefly summarize the distinctiveness of the years from 30 to 45 in terms of physical
health, well-being, and cognitive development, then highlight the collision of developmental
tasks in the work and family domains.
Physical Health and Well-Being
Physical strength and stamina generally decline after the twenties. By the early thirties,
the peak of athletic performance has passed, and it takes longer to recover from injuries than in
the twenties (Bruner et al., 2010; Houglum et al., 2010). Primary aging leads to declines in the
basal metabolic rate, and because fewer calories are burned when a person is resting, weight gain
and obesity increase (Peitilainen et al., 2008). Nevertheless, most people experience good
physical functioning during established adulthood, and the years from age 30 to 45 are in some
respects the physically healthiest of the entire lifespan. During these years the immune system is
strong and susceptibility to most infectious diseases is low. Established adults are not yet at risk
for the types of diseases that commonly occur in middle and later adulthood, most notably cancer
and heart disease. Furthermore, established adults have healthier eating and sleeping patterns
than emerging adults (Braveman, Egerter, & Williams, 2011) and are far less likely to engage in
risky behaviors that may endanger health, including risky driving, substance use, and risky
sexual behavior (Arnett, 2015).
The literature on well-being across the adult lifespan is complex and difficult to interpret
(Arnett, 2018). Probably the best data come from the MIDUS study, which surveyed a national
sample of adults ages 25-74 in the United States on multiple domains of life satisfaction,
including marriage, work, relationships with children, and finances (Lachman, 2004; Lachman et
al., 2015). While overall life satisfaction was more or less flat across age groups, each domain
showed a different pattern of change with age. During the age period of 30-45, satisfaction was
highest in the domains of marriage and relationships with children and lowest for finances and
sexuality. In 10-year longitudinal data from the study, positive affect was lower across ages 25-
39 than at ages 50 and above. However, emerging and established adults were both more
optimistic about the future than their elders were; expected future life satisfaction was highest at
ages 25-39 and fell steadily after age 40. More research is needed to better understand
trajectories of health and well-being in established adulthood across countries and cultures.
Cognitive Development
In many ways, cognitive development is enhanced during established adulthood. The
landmark Seattle Longitudinal Study showed that intelligence rises through the thirties and early
forties in nearly all domains, including Spatial Orientation, Inductive Reasoning, and Verbal
Ability (Schaie, 2013). The one exception is Perceptual Speed, an aspect of fluid intelligence that
declines steadily from the mid-twenties onward.
Established adulthood is also the period when expertise—extensive knowledge and skills
in a specific field—is most likely to be reached (Chi, Glaser, & Farr, 2014). This is because it
takes about 10 years of study or practice in a field to attain expertise, and most people begin
steady work in a specific field in their twenties. The development of expertise in established
adulthood is not confined to high-SES fields. A study of food-services workers found that
expertise—defined in terms of knowledge (of menu items and food presentation); organizational
skills (such as handling orders efficiently); and social skills (such as confidence in interacting
with customers)—increased from the 20s to the 30s and 40s (Perlmutter et al., 1990). Attaining
expertise enables people to move from problem solving to problem finding, as they use their
acquired knowledge and skills to think in new ways (Hu, Shi, Han, Wang, & Adey, 2010).
Because creativity requires a base of expertise, its peak comes only after expertise has
been sufficiently developed, usually in the thirties. Consequently, during established adulthood,
creativity has the potential to flourish as established adults are able to combine expertise with
openness to new ideas, tolerance for ambiguity, and a willingness to take intellectual risks
(Sternberg, 2016). A number of studies of people with exceptional accomplishments have found
that their creative achievements rise during established adulthood and peak in the late thirties or
early forties, then gradually decline through middle and late adulthood (Simonton, 2010). Even
though expertise continues to rise through middle adulthood and beyond, “familiarity breeds
rigidity” (Mednick, 1963), and beyond established adulthood, expertise tends to steer people
down the same cognitive paths rather than inspiring creative new ideas.
The Career-and-Care-Crunch: The Developmental Challenge at the Heart of Established
Adulthood
In all societies, work and family are the two main domains of adult life. Work and family
are varyingly defined. “Work” may be inside or outside of the home. “Family” may entail
marriage and caring for children, caring for children outside of marriage, marrying but not
having children, remaining unmarried and serving as a devoted aunt or uncle, or serving as a
caretaker for aging parents. Across the forms that work and family may take, contemporary
adulthood brings a pile-up of demands from age 30 to 45 as people pursue multiple work and
family goals simultaneously. While some goals may be interdependent such that success in one
domain facilitates success in others (e.g. securing a good job may generate resources to provide
for children), others may be incompatible, placing competing demands on insufficiently available
resources (e.g. working toward advancement at work may reduce time with family; Riediger,
Freund, & Baltes, 2005).
Important changes in work and family demands that have occurred in recent decades
have led to this pile up of demands and competing goals during the 30s and 40s. We believe that
this merits recognition, and it is part of the impetus for conceptualizing a theory of established
adulthood. To summarize the demographic patterns presented earlier: The twenties are often
devoted to obtaining education and sampling occupational paths before making an occupational
commitment at around age 30. First marriages also typically take place around age 30, and
couples often feel a need, desire, and obligation to spend time together in order to develop a solid
relational foundation for the future (Cherlin, 2010). The birth of the first child also takes place
around age 30 across developed countries. Consequently, established adulthood brings a
simultaneous collision of demands, goals, and aspirations as people attempt to progress at work
and achieve a deep level of intimacy in a long-term romantic relationship while also responding
to the relentless demands of caring for one or more young children. We call this the Career-and-
Care-Crunch.
The competing demands of work and family for adults have long been studied as work-
family balance or work-family conflict (e.g., Wayne, Butts, Casper, & Allen, 2017).
This literature generally supports the idea proffered here: That conflicts between demands of
work and family increase from the twenties to the thirties and forties and then decline in later
decades (Huffman et al., 2013). Consequently, during this period people must adjust the extent to
which they engage in boundary management, separating or integrating the boundaries between
their work and home life (Kossek, Lautsch, & Eaton, 2006).
We propose the new term Career-and-Care-Crunch to draw attention to our theoretical
proposal that the Crunch peaks in established adulthood. As part of this conception, we recognize
that the psychosocial demands entailed may go beyond child care and include relations with
parents, friends, community organizations, and even pets. Furthermore, our Crunch concept
highlights that the conflict at ages 30-45 is not just between work and family domains but
between multiple demands within the family domain. The term also underscores that the
intersecting demands at this age period often require something to be sacrificed and people may
find themselves feeling like they are coming up short in work or family or both. Consequently,
we believe that these competing demands are best described as a Crunch.
Romantic Partnerships and the Crunch
The impact of the Crunch is perhaps most evident in research on established adults’ long
term romantic relationships, typically marriage. The period following entry to marriage tends to
be high in terms of happiness and marital satisfaction, and newlywed couples often behave in
ways consistent with idealized conceptions of the soul-mate marriage by downplaying negative
feelings, avoiding conflict, and highlighting the positive characteristics of their partner and their
relationship (Cherlin, 2010; Huston, Coughlin, Houts, Smith & George, 2011). During this
period couples spend a good deal of time together, as they work to establish marital intimacy.
When long-term romantic partners become parents, however, additional strain is placed
on the intimate partnership. The transition to parenthood, lasting from conception until the child
is one year of age, is a major life-altering change (Fillo, Simpson, Rholes, & Kohn, 2015;
Goldberg, 2010; Sheedy & Gambrel, 2019; Young, Roberts, & Ward, 2019). The birth of a child
requires a romantic partnership comprised of two people to evolve into a three-person family
system and requires adults to take on a new role and identity as parent (Goldberg, 2010). While
the transition to parenthood can bring joy and excitement, it also brings challenges and stressors
that may leave parents feeling exhausted, overwhelmed, and isolated (Mickelson & Biehle, 2017;
Nazarina-Roy, Schumm, & Britt, 2014). New parents must often return to work within a few
weeks or months of the birth and abruptly learn to negotiate the competing demands of work and
family life (Borelli, Nelson, River, Birken, & Moss-Racusin, 2017). It is no surprise then that
new parents typically experience decreases in relationship satisfaction and intimacy, which may
increase relationship conflict (Mickelson & Biehle, 2017). Furthermore, divorce risk rises steeply
in the early years of parenthood (Gottman, 2014). In sum, the Crunch entails not just a conflict
between work and family demands but a conflict within the family between the demands of child
care and the demands of maintaining an intimate partnership.
A Gendered Crunch: The Harsher Challenge for Women
A half century after the rise of feminism, gender roles in most developed countries are
less sharply defined than previously, and in established adulthood heterosexual couples often
share many of the duties that traditionally fell to one gender or the other (Gottman & Gottman,
2017). Historically, few fathers in developed countries involved themselves in the daily duties of
child care. For example, according to national U.S. data, as recently as 1965 men spent only 10
minutes per day with their children, compared to 85 minutes for women (Cotter & Pepin, 2017).
By 2016, men’s time with children had risen substantially, to about 58 minutes.
Nevertheless, American mothers’ time with children – 90 minutes per day in 2016 –
remains higher than fathers’, and mothers in heterosexual relationships still provide the majority
of child care in infancy and beyond (Nazarina-Roy, Schumm & Britt, 2014). This may reflect
that women, rather than men, continue to be socialized into caregiving roles from a young age
(Fillo, Simpson, Rholes & Kohn, 2015). Several studies have found that gender roles in
developed countries become more traditional following the birth of the first child (Dew &
Wilcox, 2011; Le et al., 2017). Developed countries vary, but even in the northern European
countries, where ideologies of parenting promoting gender equality are strongest, young mothers
are far more likely than young fathers to take parental leave and to have the main responsibilities
for parenting (OECD, 2018d).
Women make a greater contribution not only to child care but to household work in
heterosexual couples. The number of hours men spend on housework remains largely unchanged
during the transition to parenthood. Women do more housework and childcare than men do even
when they make more money than their husbands (OECD, 2017; Wang, 2019). It is no surprise
then that the division of labor in childcare and household tasks is often a source of conflict for
new parents (Nazarina-Roy, Schumm & Britt, 2014).
A key consequence of the gendered Crunch is the “motherhood wage penalty.” Women
who have children make less money than women in the same profession who do not have
children, whereas men experience no comparable penalty and may even experience a wage
enhancement compared to men without children (Budig, Misra, & Boeckmann, 2016). The
motherhood penalty is due primarily to leaving the work force temporarily or reducing
employment hours, thus forgoing crucial years of building expertise, and is highest for women
with the most education (England et al., 2016). Women experience the motherhood penalty
across developed countries, although it is smaller in countries that provide high-quality,
affordable child care (Cukrowska-Torzewska, 2017).
Social Class and the Crunch: The Special Case of the United States
In some developed countries, universal social policies such as paid parental leave and
government-funded child care reduce class differences in the experience of the Crunch
(Cukrowska-Torzewska, 2017). However, the United States has the greatest inequalities of
wealth of any developed country and the least generous social programs, so many aspects of life,
including the Crunch, are more deeply influenced by social class (Glass et al., 2016).
Specifically, the lower the social class status in the United States, the more likely it is that the
Crunch will take place early, and alone.
In recent decades, the rise in the median age of first childbirth to around age 30 has taken
place mainly among women in the highest social class, i.e., who have a college degree
(Hymowitz, Carroll, Wilcox, & Kaye, 2013). In contrast, among those who have only some
college, or a high school diploma or less, median age at first childbirth is only in the mid-
twenties. Furthermore, a large and growing social class disparity has developed in recent decades
in the likelihood that the first birth will take place in the context of marriage. Among young
Americans with a college education, only 12% of first births take place outside of marriage,
compared to 58% for those with a high school diploma or some college and 83% for those with
less than a high school diploma (Hymowitz et al., 2013). Unmarried parents may be cohabiting,
but in the U.S. cohabiting relationships are three times as likely as marital relationships to
dissolve within five years of the birth of a first child.
The main consequence of an earlier Crunch is that the demands of raising children may
occur before new parents have had time to finish their education, try different occupational
options and establish a definite direction, and develop expertise in their field. The likely result is
that long-term career development will be impaired. Similarly, for single parents, the Crunch of
trying to make occupational progress while caring for a young child is intensified and prospects
for success are less promising when there is no partner with whom to share the responsibilities of
child and household on a daily basis. The stress of being a single parent is compounded by
financial stress; single mothers in particular often have low incomes, partly because they have
less education (Garrett-Peters & Burton, 2016). Furthermore, given the many challenges and
strains faced by couples in adjusting to and caring for a child, it is not hard to see how difficult it
must be for a single parent to handle these challenges primarily alone.
Another distinctive feature of the United States is that social class and ethnicity are
deeply intertwined. African Americans and Latinx persons are more likely than people in other
ethnic groups to grow up poor and have lower educational attainment. They also have lower
median ages of first childbirth than Whites or Asian Americans do, and are more likely to be
single mothers. In part because of this, African American and Latina single mothers often receive
child care assistance from their own mothers (Taylor & Conger, 2017). In short, the timing and
content of the Crunch varies among American ethnic groups, and this variation should be an
important focus of research in a new field of established adulthood.
Variations in Established Adulthood
Although most established adults in developed countries experience the Crunch, there are
diverse alternative paths through established adulthood. In addition to the variations by gender
and social class just described, we briefly describe several other variations here.
Variation 1: The Single Life
Although the timing of entry to marriage is later than in the past, it remains true that over
80% of young people in developed countries enter marriage or another committed long-term
partnership by their 30s (Fletcher et al., 2015). Nevertheless, a substantial proportion of
established adults remain unmarried past age 40. Some may not find a partner with whom they
are willing to commit to a long-term relationship (DeLyser, 2014), whereas others may remain
“single by choice” (DePaulo, 2006). Generally, health and happiness are high for people who
remain single throughout established adulthood. Their life satisfaction is not as high as for
happily married people, but it is higher than for established adults who are separated, divorced,
or unhappily married (DePaulo, 2012). Rates of established adults who remain single are rising
in Asian countries such as Japan and South Korea, apparently due to young women’s resistance
to the cultural expectations of duty and submission imposed on them following marriage and
(especially) motherhood (Rosenberger, 2007; Yamada, 2017). Marriage rates are also declining
in China due to the imbalance in the ratio of women to men created by years of the one-child
policy that favored male children over females (Hudson & Den Boer, 2002; Nelson & Chen,
2007). Given the increasing numbers of persons who are single during established adulthood,
there is a need to investigate the correlates and outcomes of singlehood in future research, in
diverse countries and cultures.
Variation 2: Coupled but No Children
Another prominent variation in established adulthood is the growing number of people in
developed countries who are choosing to remain “child free.” While men may occasionally be
questioned about the decision to remain child free, sociocultural expectations around
childbearing for women and beliefs that motherhood is a central component of the female role
mean that women who choose not to have children are often stigmatized and face social
exclusion and discrimination (Doyle, Pooley, & Breen, 2013). In addition, child-free couples are
often not regarded as a “family,” both socioculturally and in the research literature (Pelton &
Hertlein, 2011). Although more same-gender partners in the past have children, in the United
States only about 8% of male same-gender partners and 24% of female same-gender partners
have one or more children (Goldberg & Conron, 2018).
It is important to note that while some established adults may be child-free voluntarily,
there are others who wish to have children but cannot, for reasons including fertility issues,
economic constraints, or reproductive choices based on susceptibility to genetic disease. For
many, being involuntarily childless is an emotionally painful experience that entails feelings of
shame, grief, and loss (Bell, 2013; Koert & Daniluk, 2017). Ultimately, however, most couples
who do not choose to overcome involuntary childlessness via adoption carve out new and
fulfilling adult identities for themselves that do not include parenthood (Pelton & Hertlein,
2011). Furthermore, their marital satisfaction is higher than for couples with children (Nelson,
Kushlev, & Lyubomirsky, 2014).
Variation 3: One Full-Time Parent
Although there are more dual-earner couples than ever across developed countries,
there are some established adult couples in which one partner works outside of the home while
the other works inside the home providing household work and childcare. This arrangement may
be due to culturally or religiously based beliefs, to job loss or other economic factors, or may be
a response to a trend in developed countries toward “intensive” parenting (Cranney & Miles,
2017; Sherman, 2009). Regardless of the reason, the Crunch may look different for established
adult parents where only one person works outside of the home. Specifically, while the working
parent may still participate in childcare and housework, some of the stresses associated with the
multiple demands of work and home may be reduced as each partner primarily focuses energy
and attention in one domain. However, the non-employed parent gives up crucial years of career
progress and expertise-building that will be difficult to make up when re-entering the work world
(Budig et al., 2016).
Variation 4: No Career, Just a Job
In a similar vein, it may be that the nature of the Crunch is different for established adults
whose goals for work are practical, focused on making a living and bringing in a paycheck.
People who are not pursuing an upward career trajectory may experience a less intense Crunch.
However, the resulting economic stress due to lower wages and higher likelihood of periods of
unemployment or underemployment could compound the Crunch. What, then, does established
adulthood look like for those in low-skilled jobs—servers in restaurants, drivers of delivery
trucks, clerks at check-out counters? These are among the questions to be investigated by
researchers in established adulthood.
Variation 5: Thriving and Arriving Versus Regret and Renovation
Variations in development during established adulthood may be connected to choices
made in the twenties. For example, work on “ourishing and oundering” in
emerging adulthood suggests that some people may be better equipped than others
to navigate the Crunch in established adulthood (e.g., Nelson & Padilla-Walker, 2013).
Those who experienced events or made choices in their twenties that led to positive
relationships, strong internalized values and identity, education or training credentials, a strong
financial foundation, and hope for the future may find that their thirties are characterized by
thriving and arriving (meeting future goals). For others, who experienced events or made
choices in emerging adulthood that led to debt, broken relationships, a lack of education and
direction, and, in some cases, addiction or a criminal record, may find that their thirties are
characterized by regret and renovation (digging out of the past), making navigating the Crunch
more challenging. Consequently, it is critical to gain a better understanding of
development during established adulthood by recognizing that development
in the thirties and forties is a continuation of developmental processes that
began earlier in life.
Policy Prospects
There is not enough space in this paper to devote much to policy prescriptions, but given
the prominence of the Crunch in established adulthood it seems appropriate to discuss at least
one policy response to it briefly. The most obvious policy to support established adults during the
Crunch is paid family leave and high-quality government-subsidized child care following the
birth of a child. One study examined well-being in relation to parental status using data across 22
economically developed countries, including the United States, Canada and a number of
European countries (Glass et al., 2016). In most countries, being a parent was negatively related
to well-being. However, in countries that provided the most social welfare benefits to parents, the
relation was reversed, and being a parent was related to higher well-being. The United States had
the fewest social welfare benefits for parents, and consequently had the largest parental
“happiness penalty” of any country. Policies that support parenting may be especially important
for people of color in the United States who are disproportionately engaged in precarious
employment (Bureau of Labor Statistics, 2011; 2019b) and who may also be single parents
(Hummer & Hamilton, 2010).
Although paid parental leave is a welcome and necessary policy response to the Crunch,
it is no panacea. One concern is that it is nearly always the mother who takes the leave, across
countries. If fathers take any leave at all, they do so for a shorter period than mothers do (OECD,
2018d). Policy that favors leave for mothers may be partly in response to the fact that it is the
mother who carried the child and gave birth and is thus likely to need a period of time to recover
physically. However, such policies result in women’s career trajectories flattening or falling to a
greater extent than men’s during the Crunch years. This may especially be the case if they have
more than one child. For these reasons, studies of the “motherhood wage penalty” have
concluded that providing affordable child care is a more effective social welfare policy than paid
parental leave in easing the Crunch (Budig et al., 2016).
Research Questions
The worth of any theoretical idea should be measured in how much research it inspires.
Many possible research questions can be generated by the idea of established adulthood. Here
are a few examples.
1. How does the experience of established adulthood vary according to culture, race,
ethnicity, and socioeconomic status?
The field of psychology in general has disproportionately focused on the experience of
White, North American, college educated, affluent adults (Arnett, 2008). As such, it is imperative
that researchers investigate the age period of 30-45 in different populations, especially
populations that have been historically marginalized. To that end, important research questions
are: Does established adulthood in some form exist across cultures? How is established
adulthood experienced by people of color in the U.S. and in other countries with racial
disparities? How does social class influence the timing and intensity of developmental demands
common to established adulthood? How do intersectional identities interact to shape established
adulthood?
2. What developmental processes take place alongside central life tasks in established
adulthood? Many of the features of established adulthood described above represent processes
rather than static developmental outcomes. An important research question is how these
processes unfold and influence one another as well as how they influence broader developmental
trajectories. For example, how do romantic relationships impact an individual’s identity and
psychological functioning, and how do they connect to other developmental tasks relating to
career progress or child care? Do established adults develop different coping skills, establish new
forms of self-regulation, or pursue their developmental tasks in a different way than in other
phases of adult life in order to manage the demands of the Crunch? Similar questions around
developmental processes can be asked for the other developmental features of established
adulthood that we presented above.
3. What happens to the optimism of emerging adulthood once people reach established
adulthood? It is well-known that emerging adulthood is a time when optimism is high. Nearly all
emerging adults believe that they will attain the kind of life they envision, even if their current
lives are not going well (Arnett, 2015). This vision typically includes all the elements of what
eventually becomes the Crunch: a rising career trajectory, an intimate partnership, and one or
more children. Once they have reached established adulthood, how do people compare and
reflect on their current lives in relation to what they had planned and hoped for as emerging
adults? Do established adults in the midst of the Crunch begin to regret occupational choices
and/or family choices (e.g., choice of spouse, timing of marriage or childbearing)? If so, how do
they respond to these regrets?
4. What is the degree and nature of stress in established adulthood? It will be important to
follow emerging adults longitudinally as they enter established adulthood and see how their
stress levels change as they take on the Crunch. It is also important to explore the nature and
degree of established adults’ stress during this process, with qualitative research that goes beyond
questionnaires. To what extent is stress engaging and fortifying, and at what point does it become
unpleasant or overwhelming? Is there a stress-reward curve that is like the Yerkes-Dodson
anxiety-performance curve, such that stress in established adulthood is rewarding up to a certain
optimal level, then becomes aversive? Stress should also be compared among established adults
who take diverse paths, e.g., comparing those who experience the full Crunch to those who
remain single or coupled but without children.
5. How do relations with parents change? To what extent do established adults rely on their
parents to help relieve the Career-and-Care-Crunch? Are established adults who experience the
Crunch closer to their parents during these years than established adults who do not have
children and thus have less need for their parents help, or does the necessity of reliance on
parents more often breed ambivalence and resentment?
6. What becomes of friendships? How do friendships in established adulthood vary? Do
established adults who experience the Crunch have fewer friendships than other established
adults, because they have less time, or just different friendships, i.e., with other parents who have
children of the same age?
7. What are the rewards and costs of diverse pathways through established adulthood? As
noted, there are many possible routes through the years from age 30 to 45. What do established
adults say about the rewards and costs of each of these options, including their own? Do their
perceptions depend on whether they have chosen their option or would have in fact preferred a
different route?
Conclusion
In one sense, some form of established adulthood has always been a part of adult
development, because in all societies most people have married, had children, and worked.
However, a new conception of established adulthood is warranted because of how these roles are
changing. Most adults have always had children, but in the past, bearing and caring for and
providing for children dominated nearly all of adult life. The advent of emerging adulthood and a
longer adult lifespan mean that today parenting is concentrated during the thirties and early
forties, followed by several decades when the responsibilities of caring for children have waned.
Nearly all adults have always worked, but only in recent decades have both men and women
worked outside the home and had similar ambitions for career development. Responsibilities
related to parenthood may collide with increased responsibilities at work as people climb the
occupational ladder. This concentrates the Career-and-Care-Crunch at ages 30 to 45 and requires
adult partners to engage in negotiation and compromise, frequently along with sacrifice and
conflict.
We hope that our conceptualization of established adulthood and the Crunch at the heart
of it will promote new developmental research on a neglected age period. However, this idea has
potential beyond the research arena. Understanding established adulthood as a distinct time of
life has implications not only for people experiencing or about to experience the Crunch, but also
for therapists and other mental health professionals working with established adults.
Additionally, understanding established adulthood as a unique developmental period with
developmental antecedents and consequences can inform policy makers who have the power to
promote programs that would alleviate the Crunch and enhance the likelihood of the “thriving
and arriving” outcome.
We have proposed the idea of established adulthood in this paper with the goal of
drawing attention to this fascinating and dynamic time of life and with the hope of inspiring
increased investigation of its developmental norms and variations, including variations by race,
ethnicity, social class, gender, and culture. There has been room in this paper for only a sketch of
a theory, and there is much to be filled in with further theorizing and research. The changes in the
life tasks and responsibilities at ages 30-45 in recent decades are likely to continue to evolve with
societies’ economic changes and continuing changes in family arrangements and gender roles.
Researchers who investigate this developmental period are sure to have much to observe and
explore in the decades to come.

... Smartphones provide continuous connectivity to the Internet and their opportunity for use is not limited by location, time, or purpose (Gui & Buchi, 2021). This aspect of unlimited access can be useful for established adults, 30-45 years old, who are juggling career responsibilities at the same time as their commitments to family life-for example as they foster personal relationships and care for children and/or aging parents (Mehta et al., 2020). However, unlimited access may also lead to high levels of use and/or overuse. ...
... Research on smartphone overuse has focused on youth (e.g., Buabbas et al., 2021;Kim et al., 2020), and emerging adults (see review from Busch & McCarthy, 2021), with little research focusing on individuals in the established adulthood stage of life (Mehta et al., 2020). This study explored smartphone use by established adults who perceive that they overuse their smartphones and/or social media. ...
... Furthermore, this study examined some of the challenges for established adults that arise from smartphone use. The results illustrate that established adults, in this study, were caught between a "career-and-care-crunch" as they tried to balance their constant connection with social ties, mainly family, and their place of employment (Mehta et al., 2020), by using their smartphones at least several times a day. Issues with smartphone use occurred when there was an unclear separation between work and personal use (Derks et al., 2014(Derks et al., , 2015Middleton & Cukier, 2006;Orlikowski, 2007). ...

Smartphone ownership and use continues to proliferate, allowing people to easily access online communication, entertainment, and information. Importantly, individuals can perceive that they overuse their smartphone and/or the social media applications (apps) they access on their devices. Much of the research on smartphone overuse has focused on youth and emerging adults, with little research focusing on individuals in the established adulthood stage of life. This study examines smartphone use among established adults who perceive that they overuse their smartphone and/or social media. As part of a larger study, we conducted in-depth interviews with 21 individuals (30–45 years old) who self-identified as smartphone and/or social media overusers. Data were collected through a pre-survey, 1-hour interview, and smartphone use screenshots. Audio-recorded interviews were transcribed and then coded using NVivo software. Participants’ average age was 35.9 years (SD = 4.1). The majority of the sample were female (67%), White (76%), and had a master’s degree or higher (76%). Participants spent an average of 215 min on their smartphone daily, primarily using social media, video conferencing, and texting apps. Issues with smartphone use occurred when there was an unclear separation between work and personal use. Participants felt pressure to always respond quickly to work emails. An effort was made to limit smartphone use for work and during family time to be present for their family. Established adults strive to balance smartphone use for personal and work purposes. Creating boundaries for how and when established adults use their smartphone may help them find this balance.
... Additionally, religion influenced individuals' lives in many other ways such as helping to deal with health issues (Jim et al., 2015) and guiding parenting practices (Godina, 2014). Given the diverse roles that established adults need to navigate (Mehta et al., 2020), religion may influence the various aspects of wellbeing, including mental, physical, and social (Reymann et al., 2015). It is therefore important to further investigate the impacts of religion on quality of life in adulthood (Day, 2017). ...
... Only recently has established adulthood been conceptualized as a distinct stage of development, spanning the ages of 30-45 years of age. According to Mehta et al. (2020), roles and identities become increasingly complex and multi-dimensional during this stage of development. Also, there are significant developmental changes that are distinct in established adulthood, including romantic relationships, career, caregiving or family, physical health, cognitive development, and wellbeing. ...

Scholars recently conceptualized ages 30–45 as a distinct stage of development called established adulthood. One important area that may be especially relevant and influential at this age stage is religiosity as it may influence established adults’ values, beliefs, and practices. At the same time, there is a dearth of research on established adulthood, especially in Black Jamaican families. Given the high prevalence of female-headed households in Jamaica, Black Jamaican established adult women’s perspectives on the role of religion in their lives is a rich area for exploration. The purpose of this study was to explore how Black Jamaican established adult women make sense of the influences of religion on their lives and development. Using framework analysis, semi-structured interviews with 20 Black Jamaican established adult women with multiple roles (e.g., mother, spouse, and employee) were analyzed. The data mapped onto three major themes: (a) the exposure of religion, (b) reactions to early religious experiences, and (c) how religion changed and guided established adult women’s lives. These themes revealed that relational agency was important in religious development. Also, from both the lifespan and life-course perspectives on religious development, the findings reflected equifinality and multifinality in the Black Jamaican established adult women’s lives, including their, values, beliefs, and practices. Implications for individuals, families, and communities are discussed.
... Typical ages at which breaks are made include 18 years (age of majority) and 65 years (workingage vs. retirement-age adults-seniors). Others include the pivot in working-age adulthood (at 45 years of age; see Mehta, Arnett, Palmer, & Nelson, 2020) from early-to mid-career and childrearing (established) adulthood to mid-to late-career and now childless (middle-aged) adulthood; 80 years and older (elderly), when agerelated hearing loss and other disabilities are quite prevalent (Goman & Lin, 2016;Hoffman, Dobie, Losonczy, Themann, & Flamme, 2017;Mahoubi, Lin, & Bhattacharyya, 2018), is another. ...

An empirical estimate of how many deaf and hard-of-hearing persons use sign language in the USA was obtained a half-century ago, but no study has measured how many people sign regardless of deafness. This study estimated the number of deaf, hard-of-hearing, and hearing adult signers. Concatenation of the 2010-2018 National Health Interview Surveys was required to provide sufficient sample size. Unadjusted and age-by-sex-adjusted sign language use prevalence across the range of hearing acuity was estimated. Adult sign language use was substantial (2.80%), with its rate of use greater for women than men and younger adults than older adults. As a group, deaf respondents had a far higher rate of sign language use than any other hearing acuity group. This study provides the first empirical estimate of adult sign language use generally, and the first update of any sign language use estimate in a half-century.
... However, the frequency of these behaviors appears to fluctuate during the adolescent years: older adolescents generally emit fewer PEBs than do younger adolescents (Krettenauer, 2017). Behaviors are thought to stabilize once adulthood is reached (around the age of 30; Mehta et al., 2020). Adults then assume the full responsibility of managing their residence, resources, and consumption habits (Nelson & Luster, 2014). ...

Introduction: Organized activities practiced in adolescence are known to foster positive development, including active citizenship. Active citizenship encompasses a wide range of behaviors, one of them being pro-environmental behaviors. Few studies focused on the developmental factors that may predict these behaviors in adults, despite their crucial role in counteracting the current climate crisis. However, prior research showed that attitudes were typically major predictors of behaviors. This study thus tested a model that posited participation in organized activities in adolescence as a predictor of pro-environmental attitudes in emerging adulthood and these attitudes as a predictor of pro-environmental behaviors in adulthood. Methods: Three hundred twenty-one participants (61% girls) from Quebec (Canada) completed all time points across a 17-year period. Participants self-reported their participation in organized activities (sports, cultural, prosocial) from ages 14 to 17, pro-environmental attitudes, from ages 18 to 22, and pro-environmental behaviors, at age 30. Results: Results revealed that pro-environmental attitudes mediate the relationship between adolescent participation in cultural activities and pro-environmental behaviors in adulthood. Practicing sporting or prosocial activities in adolescence did not predict stronger pro-environmental attitudes or behaviors. Interestingly, pro-environmental attitudes consistently predicted pro-environmental behaviors later in life. Conclusions: These findings and prior research suggest that participation in cultural activities may provide a space to discuss, imagine change, and cultivate sensitivity towards nature. This may contribute to the development of pro-environmental attitudes and behaviors later in life.

These are arguably broad age ranges but reflect recent conceptualizations of distinct developmental periods in adulthood (e.g., Infurna et al., 2020;Mehta et al., 2020). Nevertheless, we observed similar patterns of results in secondary analysis in which these age categories were not collapsed (see Supplemental Tables S16-S18). ...

We examined age group differences in hedonic adaptation trajectories of positive and negative affect (PA/NA) at different arousal levels during the severe societal restrictions that governments implemented to contain the first wave of the COVID-19 pandemic (March to June 2020). Data from 10,509 participants from 33 countries and 12 weekly assessments were used (67% women, aged 18 to 85 +, on average 318 participants per country (SD = 434) and 5.6 assessments (SD = 2.5) per participant). Multilevel models (level 1: assessments, level 2: participants, level 3: countries) were fit to examine trajectories of low to high arousal PA and NA during the phase of tightening societal restrictions, the phase of stable peak restrictions, and the phase of easing restrictions separately. During the entire study period mean levels of PA were lower in emerging and young adults (aged 18-44) than older adults, whereas mean NA levels were higher. During peak societal restrictions, participants reported increasingly more PA, especially high-arousal emotions (d = .36 per month vs. .19 unaroused). NA levels decreased over time, especially high-arousal emotions (d = .35 vs. .14 p/month). These hedonic adaptation trajectories were largely similar across age groups. Nevertheless, up to 30% of the participants increased in NA and up to 6% decreased in PA, against the general trend, demonstrating substantial individual differences in emotional adaptation. Finally, heterogeneity in the effects of time on affect was larger on the individual level than the country level. Emotional recovery trajectories during the first lockdown in the COVID-19 pandemic were virtually similar across age groups in 33 countries, across valence and arousal levels, suggesting age advantages in emotional well-being remain restricted to mean-level differences rather than emotion dynamics.

... El periodo central de la adultez es el que desde la formulación original de Erikson se ha considerado como el particularmente crítico para el desafío generativo, que si no se resuelve satisfactoriamente conlleva el predominio del estancamiento y la autoabsorción . Abarca dos momentos diferenciados, aunque los límites de edad son siempre algo arbitrarios: la adultez joven que también se empieza a conocer como la «adultez establecida» (established adulthood) aproximadamente entre los 30 y 45 años y la adultez media o mediana edad propiamente dicha entre los 45 y 60 años (Mehta et al., 2020). Durante la primera fase los adultos deben ser capaces de gestionar demandas, con frecuencia conflictivas entre sí, referidas a cuidados familiares, avances en la carrera laboral y mantenimiento de relaciones de intimidad. ...

... It is important to note that these symptoms may also be contributed to by other salient issues (e.g., body image, sexuality and fertility concerns, hormonal changes) facing younger women with breast cancer [35]. Moreover, as established adulthood (ages 30-45) is often a demanding period in the life span, involving the career-and-care-crunch of balancing the responsibilities of children, an intimate partnership, and a career [36], coping with the recovery from surgery during this age period may add another layer of psychological demands, and consequent difficulty with adjustment and functioning. Alternatively, younger patients may have had higher expectations regarding their level of functioning in the postoperative period. ...

Purpose Younger age is a risk factor for worse pain outcomes following breast cancer surgery, yet little is known about how younger women’s psychological state may contribute to their pain experience. Using prospectively collected longitudinal data from a surgical cohort, we examined whether early postoperative psychological distress at 2 weeks mediated the association between younger age and subsequent worse pain-related functioning 3 months after surgery. Methods Patients (N = 159) were recruited before breast cancer surgery into this longitudinal cohort study. Age at time of surgery, psychological distress (anxiety, depression, and sleep disturbance) assessed 2 weeks postoperatively, and impact of surgical pain on cognitive/emotional functioning and physical functioning assessed 3 months postoperatively were used for analysis. Results Younger age was associated with greater depression, anxiety, and sleep disturbance 2 weeks postoperatively. Younger age was also associated with greater ratings of pain impacting cognitive/emotional functioning and physical functioning 3 months postoperatively. The association between younger age and worse cognitive/emotional impact of pain was mediated by greater anxiety and sleep disturbance. Similarly, the association between younger age and worse physical impact of pain was mediated by greater sleep disturbance. Conclusion The degree of anxiety and sleep disturbance that occur early after breast surgery may contribute to greater chronic pain-related functional disability among younger patients. Anxiety and sleep disturbance are modifiable with behavioral interventions, making them potential perioperative targets to improve long-term outcomes in young breast cancer survivors.

Objective: Accumulated evidence indicates both stable and malleable parts of inter-individual differences in the broad Big Five domains. Less is known, however, about stability and change at the more diversified facet level. With the current study, we fill this gap by investigating personality stability and change across midlife and old age. Method: We apply local structural equation measurement models and second-order growth curve models to four waves of data obtained with the full NEO Personality Inventory (NEO-PI-R) collected over 11 years from 1,667 adults (Mage =62.69 years, SDage =15.62, 55% female) who participated in the Seattle Longitudinal Study. Results: Measurement invariance analyses indicated that the psychometric properties of the NEO-PI-R facets are comparable across time and age. Results revealed substantial rank-order stabilities across all facets, yet the exact pattern varied strongly between facets of the same trait and across traits. Mean-level change of facets from midlife to old age largely mirrored the mean-level change observed for the broader traits. Conclusion: We discuss conceptual implications and argue that in the face of overall stability across midlife and old age, changes in the rank-ordering of people reveals a much more complex and diverse pattern of development than analyses at the trait level suggest.

We examined the link between types of intergenerational solidarity with grandparents among young adults in emerging adulthood and whether they provided instrumental and emotional support to their older parents in established adulthood. We used the 2000 and 2016 waves of the longitudinal study of generations and a sample of 229 grandmother–child and 175 grandfather–child dyads. Latent class analysis identified three classes describing intergenerational solidarity with grandparents ( tight-knit, detached, and intimate-but-geographically distant) in grandmother–child and grandfather–child dyads in emerging adulthood. Path analyses showed that young adults who had a tight-knit relationship with their grandparents in emerging adulthood provided more instrumental and emotional support to their parents in established adulthood, compared with those who had a detached relationship with their grandparents in emerging adulthood. Results are interpreted in contexts of multigenerational interdependence within families and the sensitivity of young adults to the needs of older parents through their earlier connection to grandparents.
