Self-determination theory posits that the degree to which a prosocial act is volitional or autonomous predicts its effect on well-being and that psychological need satisfaction mediates this relation. Four studies tested the impact of autonomous and controlled motivation for helping others on well-being and explored effects on other outcomes of helping for both helpers and recipients. Study 1 used a diary method to assess daily relations between prosocial behaviors and helper well-being and tested mediating effects of basic psychological need satisfaction. Study 2 examined the effect of choice on motivation and consequences of autonomous versus controlled helping using an experimental design. Study 3 examined the consequences of autonomous versus controlled helping for both helpers and recipients in a dyadic task. Finally, Study 4 manipulated motivation to predict helper and recipient outcomes. Findings support the idea that autonomous motivation for helping yields benefits for both helper and recipient through greater need satisfaction. Limitations and implications are discussed.

Four studies examined the effects of nature on valuing intrinsic and extrinsic aspirations. Intrinsic aspirations reflected prosocial and other-focused value orientations, and extrinsic aspirations predicted self-focused value orientations. Participants immersed in natural environments reported higher valuing of intrinsic aspirations and lower valuing of extrinsic aspirations, whereas those immersed in non-natural environments reported increased valuing of extrinsic aspirations and no change of intrinsic aspirations. Three studies explored experiences of nature relatedness and autonomy as underlying mechanisms of these effects, showing that nature immersion elicited these processes whereas non-nature immersion thwarted them and that they in turn predicted higher intrinsic and lower extrinsic aspirations. Studies 3 and 4 also extended the paradigm by testing these effects on generous decision making indicative of valuing intrinsic versus extrinsic aspirations.

Recent advancements in communication technology have enabled billions of people to connect over great distances using mobile phones, yet little is known about how the frequent presence of these devices in social settings influences face-to-face interactions.In two experiments, we evaluated the extent to which the mere presence of mobile communication devices shape relationship quality in dyadic settings. In both, we found evidence they can have negative effects on closeness, connection, and conversation quality. These results demonstrate that the presence of mobile phones can interfere with human relationships, an effect that is most clear when individuals are discussing personally meaningful topics.

Prior research suggests that, on average, disclosing sexual identity (being “out”) yields wellness benefits for lesbian, gay, and bisexual (LGB) individuals. LGB individuals vary, however, both in how much they disclose their sexual orientation in different social contexts and in the experiences that follow from disclosure. The present research examines this within-person variation in disclosure and its consequences as a function of the autonomy supportive versus controlling character of social contexts. LGB individuals rated experiences of autonomy support and control in the contexts of family, friends, coworkers, school, and religious community, as well how “out” they were, and their context-specific self-esteem, depression, and anger. Findings from multilevel modeling revealed that LGB individuals were more likely to disclose in autonomy supportive contexts. Additionally, whereas disclosure was associated with more positive well-being in autonomy supportive contexts, in controlling contexts it was not. Practical and research implications are discussed.

Although the time adolescents spend with digital technologies has sparked widespread concerns that their use might be negatively associated with mental well-being, these potential deleterious influences have not been rigorously studied. Using a preregistered plan for analyzing data collected from a representative sample of English adolescents (n = 120,115), we obtained evidence that the links between digital-screen time and mental well-being are described by quadratic functions. Further, our results showed that these links vary as a function of when digital technologies are used (i.e., weekday vs. weekend), suggesting that a full understanding of the impact of these recreational activities will require examining their functionality among other daily pursuits. Overall, the evidence indicated that moderate use of digital technology is not intrinsically harmful and may be advantageous in a connected world. The findings inform recommendations for limiting adolescents' technology use and provide a template for conducting rigorous investigations into the relations between digital technology and children's and adolescents' health.

Given the high costs of stress for both mental and physical health, understanding of how stress is incurred and how it is coped with has both theoretical and clinical significance. Self‐determination theory (SDT), a broad framework for understanding motivation and personality, speaks to many issues concerning stress‐related phenomena. Research based on SDT suggests that both less stress incursion and better coping with demanding events are associated with greater autonomous functioning, higher mindfulness, more interest‐taking in internal events, and lifestyles focused on pursuing intrinsic over extrinsic goals, among other factors. These topics are discussed within the growing body of empirical research stemming from SDT and linkages are drawn with the larger literature on stress and coping.
