Happiness not only feels good, it is good. Happier people have
more stable marriages, stronger immune systems, higher
incomes, and more creative ideas than their less happy peers
(Lyubomirsky, King, & Diener, 2005). Furthermore, cross-
sectional, longitudinal, and experimental studies have demon-
strated that happiness (i.e., long-term positive affect or
well-being) is not merely a correlate or consequence of suc-
cess but a cause of it (Lyubomirsky, King, & Diener, 2005).
For the majority of people around the globe who report want-
ing to be happy (Diener, 2000), these findings would be dis-
heartening if happiness could not be achieved intentionally.
Despite evidence suggesting that individual differences in
well-being are strongly influenced by genetics (e.g., Lykken &
Tellegen, 1996), researchers have theorized that much of peo-
ple’s happiness is under their control (Lyubomirsky, Sheldon,
& Schkade, 2005). A study that combined results from 51 ran-
domized controlled interventions found that people prompted
to engage in positive intentional activities, such as thinking
gratefully, optimistically, or mindfully, became significantly
happier (Sin & Lyubomirsky, 2009).
By examining the characteristics of dispositionally happy
people (e.g., their tendencies to be grateful, exhibit optimistic
thinking, and engage in prosocial behavior; Lyubomirsky,
2001), researchers have been able to posit activities that
might increase people’s happiness if deliberately practiced.
We define positive activities as simple, intentional, and regular
practices meant to mimic the myriad healthy thoughts and
behaviors associated with naturally happy people. The effi-
cacy of numerous positive activities for improving well-being
has now been tested empirically. Experimenters have
prompted people to write letters expressing gratitude (Boehm,
Lyubomirsky, & Sheldon, 2011; Lyubomirsky, Dickerhoof,
Boehm, & Sheldon, 2011; Seligman, Steen, Park, & Peterson,
2005), to count their blessings (Emmons & McCullough,
2003; Lyubomirsky, Sheldon, & Schkade, 2005; Seligman et
al., 2005), to perform kind acts (Della Porta, Jacobs Bao, &
Lyubomirsky, 2012; Lyubomirsky, Sheldon, & Schkade, 2005;
Sheldon, Boehm, & Lyubomirsky, 2012), to cultivate their
strengths (Seligman et al., 2005), to visualize their ideal future
selves (Boehm et al., 2011; King, 2001; Layous, Nelson, &
Lyubomirsky, 2012), and to meditate (Fredrickson, Cohn,
Coffey, Pek, & Finkel, 2008). All of these practices are brief,
self-administered, and cost-effective.
Factors Affecting the Success of Positive

they work (Sin & Lyubomirsky, 2009), but under what condi-

How Do Simple Positive Activities Increase
Well-Being?
Sonja Lyubomirsky and Kristin Layous
University of California, Riverside
Abstract
Theory and research suggest that people can increase their happiness through simple intentional positive activities, such as
expressing gratitude or practicing kindness. Investigators have recently begun to study the optimal conditions under which
positive activities increase happiness and the mechanisms by which these effects work. According to our positive-activity
model, features of positive activities (e.g., their dosage and variety), features of persons (e.g., their motivation and effort),
and person-activity fit moderate the effect of positive activities on well-being. Furthermore, the model posits four mediating
variables: positive emotions, positive thoughts, positive behaviors, and need satisfaction. Empirical evidence supporting the
model and future directions are discussed.

mechanisms that underlie the positive activity’s successful
improvement of well-being. Furthermore, the extent to which
any activity feature influences a positive activity’s success
depends on the fit between the person (e.g., his or her person-
ality or culture) and that activity feature (e.g., dosage or social
support; represented in Fig. 1 as person-activity fit).
Moderators
Using randomized controlled studies, researchers have identi-
fied several conditions under which positive activities most
effectively enhance happiness. Activity features concern the
positive activity itself (e.g., what type of behavior it is and
how often it is practiced), whereas person features pertain to
the person practicing the positive activity (e.g., whether he
or she is motivated to pursue happiness). Finally, person-
activity fit is the customized match between activity and per-
son features.
Features of the activity. Features of positive activities—
including their dosage, variety, sequence, and built-in social
support—all influence their success at increasing happiness.
For example, as with any medical or psychological treatment,
the dosage (i.e., frequency and timing) of a positive activity
matters. In one study, performing five kind acts in one day
each week (for 6 weeks) resulted in larger increases in well-
being than did performing five kind acts throughout the week
(Lyubomirsky, Sheldon, & Schkade, 2005), a pattern indicat-
ing that “watering down” positive activities by spreading them
out might limit their potency. Other positive activities, how-
ever, could easily be overdone. For example, in another study,
counting one’s blessings was less effective three times per
week than once per week (Lyubomirsky, Sheldon, & Schkade,
2005). What is interesting is that both studies suggested that
positive activities performed once a week are maximally
effective, possibly because many cultural routines (involving
work, worship, and even television) are conducted weekly.
Fig. 1. The positive-activity model, which aims to explain how and why performing positive activities makes people happier. As
illustrated at top, positive activities increase positive emotions, positive thoughts, positive behaviors, and need satisfaction, all of
which in turn enhance well-being. Features of positive activities (e.g., dosage and variet y) and of the person (e.g., motivation and
effor t) inf luence the degree to which the activities improve well-being. An optimal person-activity fit (i.e., the overlap between
activity and person features) further predicts increases in well-being.
Positive-Activity Model 59
Determining the ideal dosage of positive activities is tricky,
however, because it likely varies by person and by activity. For
example, in naturalistic settings, people report practicing
happiness-increasing activities several times a week for more
than an hour each time (Parks, Della Porta, Pierce, Zilca, &
Lyubomirsky, 2012), and in one study, users of a positive-
activity smartphone application reported bigger benefits when
they logged in more frequently (Parks et al., 2012, Study 3).
Perhaps when people are free to choose their happiness-
increasing activities, they do not view the activities as cumber-
some and gladly perform them for longer and more often.
Hence, person–activity fit likely governs optimal dosage.
Furthermore, when people choose their own positive activi-
ties rather than following an experimenter’s instructions, they
may be more likely to vary their practices. Theory and research
suggest that positive changes in people’s lives (e.g., beginning
an exercise regimen; Glaros & Janelle, 2001) are more likely
to promote sustained boosts in well-being if the events gener-
ated by the positive changes are varied (for a review, see
Lyubomirsky, 2011). For example, participants who performed
varied kind acts every week increased their levels of well-
being more than did participants who performed the same kind
acts (Sheldon et al., 2012).
Variety matters not only to the practice of a single positive
activity but also to the practice of multiple activities. Indeed,
participants in the naturalistic study reported performing
almost eight different positive activities simultaneously (Parks
et al., 2012), and participants in a Web-based study obtained
the biggest benefits when practicing two or four positive activ-
ities concurrently (Schueller & Parks, 2012). Further evidence
has suggested that certain positive activities might be good
“starter” activities. U.S. participants who began a 6-week hap-
piness intervention by writing letters expressing gratitude
experienced greater increases in well-being than did those
who began by performing acts of kindness (Layous, Lee, Choi,
& Lyubomirsky, 2012). Expressing gratitude might have
served as a trigger that precipitated an immediate upward spi-
ral of positive emotions (Fredrickson, 2001) or galvanized
people to “pay it forward,” thereby leading them to exert more
effort and ultimately reap greater benefits.
Engaging in positive activities, like making other behav-
ioral changes, is also more successful when the doers of posi-
tive activities have social support (Bandura, 1986). For
example, participants who received autonomy-supporting
messages from a peer while performing kind acts saw larger
improvements in happiness than those who did not receive
social support or who performed a control activity (Della Porta
et al., 2012). Similarly, students who read an empathetic peer
testimonial about the challenges of an optimism-boosting
exercise experienced greater increases in positive affect than
all other groups (Layous, Nelson, & Lyubomirsky, 2012). The
results from these two studies indicate that even virtual social
support (e.g., through social media) can bolster the benefits of
positive activities.
Factors like variety and social support can conceivably be
applied to any positive activity (see the list of variables under
the “Across” heading in the “Activity Features” box in Fig. 1).
Other factors, however, differentiate positive activities from
one another (see the list of variables under the “Between”
heading in the “Activity Features” box in Fig. 1) and hence
may cause certain activities to work best for certain people.
For example, positive activities can be relatively self-oriented
(e.g., practicing optimism) or other-oriented (e.g., expressing
gratitude). Collectivists might benefit more from other-
oriented positive activities and individualists from self-
oriented activities (for suggestive evidence, see Boehm et al.,
2011). Further, certain positive activities are social-behavioral
in nature (e.g., being kind), whereas others are reflective-
cognitive (e.g., savoring happy times), potentially benefitting
particularly lonely and frazzled individuals, respectively.
Finally, positive activities differ in their time orientation—they
may be focused on the past (e.g., expressing gratitude), the
present (e.g., savoring the moment), or the future (e.g., thinking
optimistically; Sin & Lyubomirsky, 2009). Older adults might
benefit more from reflecting on their legacies, whereas youths
might benefit more from visualizing bright futures.
Features of the person. Overall, positive activities that have
optimal features are more likely to promote durable well-
being. However, attributes of the person engaging in the activ-
ity also matter. As illustrated in Figure 1 (see the “Person
Features” box), for people to benefit from a positive activity
(or any self-improvement behavior, for that matter), they
have to effortfully engage in it (Layous, Lee, et al., 2012;
Lyubomirsky et al., 2011), be motivated to become happier
(Deci & Ryan, 2000; Lyubomirsky et al., 2011), and believe
that their efforts will pay off (Ajzen, 1991; Bandura, 1986;
Layous, Nelson, & Lyubomirsky, 2012). For example, partici-
pants who deliberately chose to complete “happiness-increas-
ing” exercises (rather than neutral ones) and who put more
effort into them (as assessed by judges) showed bigger gains
in well-being (Lyubomirsky et al., 2011).
In addition to people’s motivation, efforts, and beliefs, peo-
ple’s personalities may affect how much they stand to gain
from positive activities. Although the association between per-
sonality and happiness is long established (Costa & McCrae,
1980), researchers are only now exploring whether individu-
als’ personalities influence positive activities’ success. Recent
evidence has shown that people who are highly extraverted
and open to experience are especially predisposed to benefit
from positive activities (Senf & Liau, 2012).
People’s initial affective state when they embark on a posi-
tive activity also predicts how much they will benefit from
it, but the evidence in this area is mixed. Some research has
suggested that people low in positive affect (Froh, Kashdan,
Ozimkowski, & Miller, 2009) or with moderate depressive
symptoms (Seligman et al., 2005) benefit the most from posi-
tive activities, perhaps because they have more room to improve.
60 Lyubomirsky, Layous
Other evidence has indicated that moderately depressed indi-
viduals have deficits that prevent them from taking full advan-
tage of some positive practices—such individuals, for example,
benefit more from simple pleasant activities than from reflective
ones (Sin, Della Porta, & Lyubomirsky, 2011). More research is
needed to identify specific activities that are optimal for indi-
viduals within specific affective ranges.
The degree to which people perceive support from their
own social network—especially support for their pursuit of
happiness—is also likely to affect their ability to reap rewards
from positive activities. We predict that happiness seekers
who feel more supported by close others in their positive prac-
tices will see relatively greater improvements in well-being
(see Wing & Jeffery, 1999, for parallel findings regarding
weight loss).
Finally, demographic variables may influence gains in
well-being from positive activities. For example, older people
benefit relatively more than younger people from practicing a
range of positive activities (Sin & Lyubomirsky, 2009), per-
haps because they have more time to commit to the activities,
take them more seriously, and engage in them more effortfully.
Also, Westerners gain more from positive activities (namely,
expressing gratitude and optimism) than Easterners do (Boehm
et al., 2011), possibly because Westerners value and express
happiness more (Diener, Suh, Smith, & Shao, 1995; Tsai,
Knutson, & Fung, 2006). Further research should examine the
role of other demographic factors, such as sex and socioeco-
nomic status. For example, people struggling to afford food
are likely to regard the pursuit of happiness as frivolous.
Person-activity fit. Although features of positive activities
and features of the doers of positive activities broadly influ-
ence those activities’ success at increasing happiness, certain
types of activities are better for certain types of people. We
predict that activity features and person features interact with
one another (note the overlap of the “Activity Features” and
“Person Features” boxes in Fig. 1). This notion of the impor-
tance of person-activity fit is supported by studies showing
that the degree to which participants report enjoying a
positive activity predicts how often they complete that activity
(Schueller, 2010) and how much happiness they derive from it
(Lyubomirsky, 2008).
Mechanisms
Although research has begun to reveal the conditions under
which positive activities increase well-being, investigators
still know little about how positive activities work and about
the processes by which they boost well-being. We posit
that positive activities are positive for an individual only to
the extent that they stimulate increases in positive emotions,
positive thoughts, positive behaviors, and need satisfaction,
which in turn increase happiness. For example, increases in
positive emotions triggered by a meditation-based positive
activity mediated the relationship between the activity and
subsequent improvements in such personal resources as social
relationships and physical health. These enhanced personal
resources then boosted life satisfaction (Fredrickson et al.,
2008). Engaging in positive activities also leads people to con-
strue life events more positively. In one study, people who
expressed gratitude and optimism reported their weekly expe-
riences as being more satisfying over time, although ratings by
independent raters did not demonstrate any objective improve-
ment in the experiences (Dickerhoof, 2007). Further, positive
activities can prompt people to engage in unrelated positive
behaviors. For example, participants instructed to “count their
blessings” increased their time spent exercising (Emmons &
McCullough, 2003).
Practicing positive activities may also boost well-being by
satisfying basic psychological needs, such as autonomy (con-
trol), relatedness (connectedness), and competence (efficacy;
Deci & Ryan, 2000). In a 6-week intervention, expressing
gratitude and optimism increased self-reported autonomy and
relatedness (but not competence), which in turn increased life
satisfaction (Boehm, Lyubomirsky, & Sheldon, 2012). In a
study that directly manipulated these hypothesized mediators,
people who engaged in autonomy- and relatedness-fulfilling
activities saw greater increases in well-being than did people
who focused on their life circumstances (Sheldon et al., 2010).
More research is needed to determine the mediating role of
competence and to investigate whether particular positive
activities might be better suited to fulfilling particular needs.
Future Directions and Conclusions
Happiness seekers no longer need rely on unsubstantiated
advice from self-help books, magazine sidebars, or infomer-
cials. Instead, a growing body of evidence based on random-
ized controlled experiments demonstrates that relatively
simple intentional changes in one’s thoughts and behaviors
can precipitate meaningful increases in happiness. Further-
more, as highlighted by the positive-activity model, investiga-
tors have begun to pinpoint (albeit likely nonexhaustively) the
conditions under which positive activities are most efficacious
and the processes by which they work. The model also reveals
gaps in empirical evidence (e.g., regarding the role of social
support) and conflicting findings (e.g., regarding the role of
one’s initial affective state) that await further research.
The positive-activity model addresses activity features and
person features that influence the success of positive activities
as people perform them. However, future research should also
investigate how people select positive activities in the first
place. For example, individuals high in sensation seeking
might choose varied and novel (rather than similar and famil-
iar) positive activities, and mildly depressed individuals might
choose relatively undemanding activities.
Our model could also be extended to predict the extent
to which doers of positive activities persist at them—and
hence continue to reap benefits (Cohn & Fredrickson, 2010;
Lyubomirsky et al., 2011; Seligman et al., 2005). One of the
Positive-Activity Model 61
obstacles to both continued engagement and continued bene-
fits is hedonic adaptation; in other words, the rewards of posi-
tive activities dissipate with time (Lyubomirsky, 2011; Sheldon
et al., 2012). To avoid adaptation, happiness seekers should
vary their positive practices (which activities to perform, how
many, how often, and with whom). Additionally, the more
motivated individuals are to pursue happiness (Lyubomirsky
et al., 2011), the more their families or cultures endorse this
pursuit, and the more resources (e.g., time, effort) they have to
accomplish it, the more likely they are to maintain their efforts
(but see Gruber, Mauss, & Tamir, 2011).
In sum, as researchers begin to understand the how, what,
when, and why of happiness-increasing strategies, they will
become better positioned to provide empirically based advice
to the millions of people—in family, school, work, health,
organizational, or mental health settings—who yearn to be
happier.
