Abstract and Figures

In the early 1980s, three studies had found that vocational similarity between romantic partners was significantly associated with couple adjustment. However, given that these studies had important methodological and statistical limitations that compromised their validity, the contribution of vocational similarity to couple functioning needs to be further explored. This study aimed to examine the potential mechanisms explaining vocational similarity within couples and the extent to which vocational similarity contributes to couple functioning, using two similarity indices: The C index and the profile similarity correlation (PSC). A sample of 104 cohabiting couples was recruited and completed online questionnaires. Results showed that vocational similarity between partners was low to moderate and was mainly explained by mating preferences. Moreover, higher vocational similarity was significantly associated with greater couple adjustment and relational stability, especially when partners were similar on the Artistic or Enterprising type. The PSC was a stronger predictor of couple adjustment and relational stability than the C index. Sharing similar vocational interests and competencies seems to help in creating and maintaining well-adjusted romantic relationships.

Abstract
In the early 1980s, three studies had found that vocational similarity between romantic partners was significantly associated
with couple adjustment. However, given that these studies had important methodological and statistical limitations that
compromised their validity, the contribution of vocational similarity to couple functioning needs to be further explored. This
study aimed to examine the potential mechanisms explaining vocational similarity within couples and the extent to which
vocational similarity contributes to couple functioning, using two similarity indices: The C index and the profile similarity
correlation (PSC). A sample of 104 cohabiting couples was recruited and completed online questionnaires. Results showed
that vocational similarity between partners was low to moderate and was mainly explained by mating preferences. Moreover,
higher vocational similarity was significantly associated with greater couple adjustment and relational stability, especially
when partners were similar on the Artistic or Enterprising type. The PSC was a stronger predictor of couple adjustment and
relational stability than the C index. Sharing similar vocational interests and competencies seems to help in creating and
maintaining well-adjusted romantic relationships.

Introduction
In Canada, 61% of adults aged 20 to 64 are either married
(46%) or in a common-law union (15%; Statistics Canada,
2021). Despite the fact that most people generally aspire to
a satisfying and long-term romantic relationship (Roberts
& Robins, 2000), a large proportion of married couples had
divorced (43%), and common-law couples separated (85%),
before their 10th wedding or couple anniversary (Statistics
Canada, 2019). Couple dissatisfaction and dissolution may
lead to poorer mental and physical health among partners
(Hawkins & Booth, 2005; Wu & Hart, 2002; Zella, 2017)
and their children (Auersperg etal., 2019), as well as indi-
vidual and societal high divorce-related costs (Schramm,
2006; Schramm etal., 2013). Thus, clarifying how romantic
partners select each other and how their respective charac-
teristics contribute to a well-adjusted relationship could help
prevent couple dissatisfaction and dissolution.
The research literature showed that numerous factors con-
tribute to couple adjustment and dissolution in individuals,
such as premarital cohabitation (Jose etal., 2010), love (Gra-
ham, 2011), parenthood and number of children (Twenge
etal., 2003), personality traits (Malouff etal., 2010; Solo-
mon & Jackson, 2014), conflict behaviors (Gottman & Gott-
man, 2017; Woodin etal., 2011), dyadic coping (Falconier
etal., 2015), attachment (Li & Chan, 2012), and stress (Ran-
dall & Bodenmann, 2009). However, a fundamental way to
study couple functioning, given its dyadic nature, is to exam-
ine couple compatibility. This construct refers to the degree
to which both partners’ characteristics match and favor a
well-adjusted relationship, no matter if partners are simi-
lar or dissimilar on these characteristics (Luo etal., 2008;

The study explored the predictive role of vocational interests in work-family conflict and work-family enrichment in 271 employed heterosexual couples. We administered questionnaires measuring vocational interests, time-based and strain-based work-family conflicts and work-family enrichment. Going beyond prior studies, we (a) utilized a dyadic paradigm to examine actor and partner effects of interest types, (b) considered two characteristics of the interest profile - differentiation and elevation, and (c) simultaneously tested (dis)similarity effects. Actor-partner interdependence modelling and dyadic response surface analysis were employed. The results revealed modest negative actor effects of Investigative, Social, and Enterprising interests on various types of work-family conflict, along with positive actor effects of Social, Enterprising and Conventional interests, profile elevation and differentiation on work-family enrichment. Partner effects supported the interpersonal relevance of people-oriented interest types. The effects obtained were similar for women and men, and evidence generally spoke against the (dis)similarity effects of interests on work-family conflict or enrichment. A higher educational level in women was associated with increased work-family enrichment but also family-work conflict. This study highlights the interdependence of vocational interests in romantic dyads and their contribution to work-family dynamics.

The present study investigated whether Black and White Americans differed on the dimensions of Holland’s RIASEC model of vocational interests. Theoretical explanations of why racial differences in interests may occur are advanced drawing on Gottfredson’s (1981) theory of circumscription and compromise, and social identity theory (Tajfel & Turner, 1986). A meta-analysis of 54 studies was conducted that included 926,462 participants and 306 effect sizes. Our results showed that, on average, Black Americans have stronger Social, Enterprising, and Conventional interests than White Americans; and White Americans have stronger Realistic and Investigative interests than Black Americans (no differences found on Artistic interests). Further, moderator analyses revealed that: (a) the Black-White gaps in Realistic, Investigative, Social, Enterprising, and Conventional interests all increase with education (in particular, with the onset of college), (b) the gaps in Social, Enterprising, and Conventional interests favoring Black Americans increase with age, and the gap in Realistic interests favoring White Americans decreases with age (although age and education effects tend to be confounded), (c) race gaps in Realistic and Social interests are larger in male samples, and (d) race gaps in Social, Enterprising, and Conventional interests may have decreased (but not disappeared) in more recent birth cohorts. We discuss these findings highlighting the roles of access to opportunity and of social identity in potentially giving rise to racial differences in interests. This research helps us discern factors that may contribute to diversity recruiting and the building of diverse talent pipelines in various careers.

Predicted that spouses would express greater adjustment on the Locke-Wallace Marital-Adjustment Scale to the extent that they were similar on 9 needs and complementary on 3 needs (Type 1) and 14 need combinations (Type 2). The needs of 66 young married couples were assessed by having them respond to a revised version of Jackson's Personality Research Form under 4 instructional sets: self, ideal self, spouse, and ideal spouse. Although all couples tended to be similar in their ideal ratings, well-adjusted spouses were more similar than poorly adjusted spouses in their self and spouse ratings, as predicted, especially in the needs for affiliation, aggression, autonomy, and nurturance. No evidence for either Type 1 or Type 2 complementarity emerged. Implications for R. F. Winch's (1955) theory of complementary needs and for past and future investigation of need compatibility are discussed. (37 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved).

Assortative mating refers to the tendency of two partners' characteristics to be matched in a systematic manner, usually in the form of similarity. Mating with a similar partner has profound implications at the species, societal, and individual levels. This article provides a comprehensive review of research on couple similarity since 1980s. The review begins with the general patterns and trends observed in couple similarity on a range of domains including demographic variables, physical/physiological characteristics, abilities, mental well-being, habitual behaviors, attitudes, values, and personality. Next the bulk of the review focuses on analyses of 4 mechanisms leading to similarity: initial active choice, mating market operation, social homogamy, and convergence. Specific future research avenues are outlined to improve understanding of these mechanisms. Finally, the review discusses genetic, social, and psychological consequences of couple similarity.

Vocational interests are important aspects of personality that reflect individual differences in motives, goals, and personal strivings. It is therefore plausible that these characteristics have an impact on individuals’ lives not only in terms of vocational outcomes, but also beyond the vocational domain. Yet the effects of vocational interests on various life outcomes have rarely been investigated. Using Holland’s RIASEC taxonomy (Holland, 1997), which groups vocational interests into 6 broad domains, the present study examined whether vocational interests are significant predictors of life outcomes that show incremental validity over and above the Big Five personality traits. For this purpose, a cohort of German high school students (N = 3,023) was tracked over a period of 10 years after graduating from school. Linear and logistic regression analyses were used to examine the predictive validity of RIASEC interests and Big Five personality traits. Nine outcomes from the domains of work, relationships, and health were investigated. The results indicate that vocational interests are important predictors of life outcomes that show incremental validity over the Big Five personality traits. Vocational interests were significant predictors of 7 of the 9 investigated outcomes: full-time employment, gross income, unemployment, being married, having children, never having had a relationship, and perceived health status. For work and relationship outcomes, vocational interests were even stronger predictors than the Big Five personality traits. For health-related outcomes, the results favored the personality traits. Effects were similar across gender for all outcomes—except 2 relationship outcomes. Possible explanations for these effects are discussed.

Vocational interests predict educational and career choices, job performance, and career success (Rounds & Su, 2014). Although sex differences in vocational interests have long been observed (Thorndike, 1911), an appropriate overall measure has been lacking from the literature. Using a cross-sectional sample of United States residents aged 14 to 63 who completed the Strong Interest Inventory assessment between 2005 and 2014 (N = 1,283,110), I examined sex, age, ethnicity, and year effects on work related interest levels using both multivariate and univariate effect size estimates of individual dimensions (Holland’s Realistic, Investigative, Artistic, Social, Enterprising, and Conventional). Men scored higher on Realistic (d = −1.14), Investigative (d = −.32), Enterprising (d = −.22), and Conventional (d = −.23), while women scored higher on Artistic (d = .19) and Social (d = .38), mostly replicating previous univariate findings. Multivariate, overall sex differences were very large (disattenuated Mahalanobis’ D = 1.61; 27% overlap). Interest levels were slightly lower and overall sex differences larger in younger samples. Overall sex differences have narrowed slightly for 18-22 year-olds in more recent samples. Generally very small ethnicity effects included relatively higher Investigative and Enterprising scores for Asians, Indians, and Middle Easterners, lower Realistic scores for Blacks, higher Realistic, Artistic, and Social scores for Pacific Islanders, and lower Conventional scores for Whites. Using Prediger’s (1982) model, women were more interested in people (d = 1.01) and ideas (d = .18), while men were more interested in things and data. These results, consistent with previous reviews showing large sex differences and small year effects, suggest that large sex differences in work related interests will continue to be observed for decades.

The aim of this study was to estimate the long-term effects of parental divorce on their offspring's mental health as well as substance-based addiction. We performed a systematic literature search on PubMed, Medline, PsyINFO, PsyARTICLES and PsycNET for the time period from 1990 until March 2018 in English language. In total 54 studies were included in the meta-analysis resulting in 117 effect sizes as well as a total sample of 506,299 participants. A significant association between parental divorce and every aspect of mental health was found with the following pooled ORs (95% CIs): Depression 1.29 (1.23-1.35), anxiety 1.12 (1.04-1.12), suicide attempt 1.35 (1.26-1.44), suicidal ideation 1.48 (1.43-1.54), distress 1.48 (1.37-1.6), alcohol 1.43 (1.34-1.53), smoking 1.64 (1.57-1.72) and drugs 1.45 (1.44-1.46) could be estimated. There was significant association between the effect sizes and the publication date specifically for distress (r = -0.995, p = .005). The results of the meta-analysis show a consistent direction of influence regarding the long-term effect of parental divorce on their children. Individuals affected by parental divorce have a higher risk of developing a variety of mental health conditions, although the effect sizes decreased from 1990 to 2017. Further research should focus on developing programmes to promote the resilience of children affected by divorce.

It has been found that the presence of negative communicative techniques and emotional flooding in marital relationships negatively relates to marital satisfaction. However, current literature has not consistently included known demographical differences (e.g., race, gender, etc.) to truly test how these variables impact marital satisfaction. This study investigated the specific impact that both emotional flooding and negative communicative techniques had on 591 married individuals’ marital satisfaction while controlling for gender, race, and length of relationship. The results indicated that emotional flooding tends to decrease as marriages go on, and refusing to talk with the partner had the greatest negative impact on relationship satisfaction regardless of demographical differences. Suggestions are provided for how therapists and practitioners can use these findings to assist couples who are using negative communication techniques and are, subsequently, experiencing marital dissatisfaction.

In this Original Voices article we summarize the past four and a half decades of our work on relationship stability and happiness and explore the theoretical implications of that empirical research. First, we briefly review the laboratory research, clinical work, and the mathematics used to understand our results and build our theory. Then we describe the sound relationship house theory, constructive blueprints for managing conflict, and the three phases of love. We use the term love in the narrow sense of the primary emotions that draw people together to form a lasting, committed relationship between lovers, regardless of sexual orientation. Although we began with no theory at all, we were led by our data and our clinical work at the Gottman Institute.

Data from 90 German committed heterosexual couples who had a least one child were used to examine the associations between chronic minor external stress, quantity and quality of time spent together as a couple, and partners' relationship satisfaction. Using an extended version of the Actor Partner Interdependence Model, the authors found significant negative indirect effects from mothers' chronic minor external stress via quality, but not quantity, of shared time to both parents' reported relationship satisfaction. Mothers' chronic minor external stress was associated with fewer reported quality time activities, which were also associated with lower reports of relationship satisfaction for both mothers and fathers. The authors did not find indirect effects for fathers' chronic minor external stress. Overall, the frequency of quality time activities may be more important for mothers, as it explained 25% of variance in their relationship satisfaction, compared with 15% in fathers' relationship satisfaction. Implications for relationship researchers and clinicians are discussed.
