Previous research has identified a robust connection between prosociality and happiness, suggesting that kindness has both hedonic and eudaimonic benefits—in the short term and in the long term. By contrast, our experiment aimed to examine people’s momentary eudaimonic feelings while engaging in kind acts for others. To that end, we randomly assigned participants to one of four positively valenced conditions that varied in their inclusion of potential “active ingredients” of prosocial behavior. Namely, engaging in kind acts for others was compared to engaging in kind acts for oneself (social element removed), extraverted behavior (kindness element removed), and open-minded behavior (both social and kindness elements removed). Participants were assessed five times over 2 weeks, each time reporting on how they felt during their assigned activities. Multilevel models revealed that relative to all other conditions, participants assigned to do kind acts for others reported a greater sense of competence, self-confidence, and meaning while engaging in those acts across the intervention period. Engaging in acts of kindness for others also led to stronger feelings of connection relative to engaging in open-minded behavior or acts of kindness for oneself but did not differ from engaging in extraverted behavior. These results illuminate the experience of positive eudaimonic feelings while one commits kind acts for others and highlight the unique benefits of prosociality compared to other positive behaviors.

Psychological inflexibility is theorized to underlie difficulties adjusting mental processes in response to changing circumstances. People show inflexibility across a range of domains, including attention, cognition, and affect. But it remains unclear whether common mechanisms underlie inflexibility in different domains. We investigated this possibility in a pre-registered replication and extension examining associations among attentional, cognitive, and affective inflexibility measures. Participants (N = 196) completed lab tasks assessing (a) emotion-induced blindness, the tendency for task-irrelevant emotional stimuli to impair attention allocation to non-emotional stimuli; (b) emotional inertia, the tendency for feelings to persist across time and contexts; and global self-report measures of (c) repetitive negative thinking, the tendency to repeatedly engage in negative self-focused thoughts (i.e., rumination, worry). Based on prior research linking repetitive negative thinking with negative affect inertia, on one hand, and emotion-induced blindness, on the other, we predicted positive correlations among all three measures of inflexibility. However, none of the three measures were related and Bayes factors indicated strong evidence for independence. Supplementary analyses ruled out alternative explanations for our findings, e.g., analytic decisions. Although our findings question the overlap between attentional, cognitive, and affective inflexibility measures, this study has methodological limitations. For instance, our measures varied across more than their inflexibility domain and our sample, relative to previous studies, included a high proportion of Asian participants who may show different patterns of ruminative thinking to non-Asian participants. Future research should address these limitations to confirm that common mechanisms do not underlie attentional, cognitive, and affective inflexibility.

Centuries of philosophical debate and decades of empirical research have sought to characterize what it means to be psychologically well. A unifying conceptual framework to organize these diverse perspectives is needed to facilitate clear communication and cumulative science within the field of well-being science. Although a handful of overarching theoretical and measurement models of well-being have been proposed, they typically make strong claims about which constructs should be included or excluded as well as the manner and degree to which well-being constructs are related to one another. Thus, these models are often not widely adopted as organizational or communicative tools, due to their exclusion of particular theoretical perspectives or disagreement among researchers about the empirical structure of well-being. While the field continues to grapple with these issues, it would benefit from a unifying conceptual framework that is broad in scope and that can flexibly accommodate diverse theoretical perspectives and new empirical advances. In this paper, I discuss the benefits of a unifying conceptual framework for well-being, as well as the challenges in its construction. Specifically, I review strengths and limitations of Park et al.’s proposed framework of “emotional well-being,” and suggest an alternative framework of “psychosocial well-being” that encompasses the diverse array of constructs that have been proposed as positive psychological aspects of well-being.

Humans use smiles — widely observed emotional expressions — in a variety of social situations, of which the meaning varies depending on social relationship and the context in which it is displayed. The homologue of the human smile in non-human primates — both due to morphological and functional similarities — is the bared-teeth display (BT). According to the power asymmetry hypothesis (PAH), species with strict linear dominance hierarchies are predicted to produce distinct communicative signals to avoid escalations of social conflicts. Hence, while the BT in a despotic species is predicted to be expressed from low- to high-ranking individuals, signaling submission, the BT in a tolerant species is predicted to be expressed in multiple contexts, regardless of rank. We tested this hypothesis in a group of 8 captive chimpanzees (Pan troglodytes), a species commonly characterized as rather despotic. An investigation of 11,774 dyadic social interactions revealed this chimpanzee group to have a linear dominance hierarchy, with moderate steepness. A Bayesian GLMM — used to test the effects of social contexts and rank relationships of dyads on the use of the BT display — indicated multi-contextual use of the BT which is contingent on the rank relationship. We also found that slight morphological and/or acoustic variants (i.e., silent bared-teeth and vocalized bared-teeth) of the BT display may have different communicative meanings. Our findings are in line with the prediction derived from the PAH for a moderately despotic species, and the view that the human smile originated from the primate BT display.

Positive psychological interventions (PPIs), programs that specifically target positive emotions, cognitions, and behaviors, have been shown to reduce depression and improve other aspects of psychological well-being. However, potential pathways linking PPIs to better outcomes have been under-explored. In this paper, we report the results of a randomized trial of a self-guided online delivered PPI called MARIGOLD (Mobile Affect Regulation Intervention with the Goal of Lowering Depression). Participants with elevated depression were randomized to receive MARIGOLD (n = 539) or an emotion reporting control condition (n = 63). In addition to testing direct effects of the intervention on depressive symptoms, we explored whether positive or negative emotion—operationalized as past day, past week, reactivity, or flexibility—mediated the intervention impact on depression. Results demonstrated that participants in the MARIGOLD condition had reduced depressive symptoms compared to controls and, although the effect did not reach statistical significance, reductions in past day negative emotion appeared to mediate this effect. Contrary to hypotheses, the intervention did not increase positive emotion compared to the control condition. Discussion focuses on the need for future studies to continue investigating the mechanisms of action for PPIs with emphasis on theoretically-based measurement and operationalization of emotion and other potential mediators to maximize the ultimate impact of PPIs on psychological well-being.

How can gratitude interventions be designed to produce meaningful and enduring effects on people’s well-being? To address this question, the author proposes the Catalyst Model of Change—this novel, practical, and empirically testable model posits five socially oriented behavioral pathways that channel the long-term effects of gratitude interventions as well as how to augment gratitude experiences in interventions to boost treatment effects and catalyze these behavioral pathways. Specifically, interventions that enhance the frequency, skills, intensity, temporal span, and variety of gratitude experiences are likely to catalyze the following post-intervention socially oriented behaviors: (a) social support–seeking behaviors, (b) prosocial behaviors, (c) relationship initiation and enhancement behaviors, (d) participation in mastery-oriented social activities, and (e) reduced maladaptive interpersonal behaviors, which, in turn, produce long-term psychological well-being. A unique feature of the Catalyst Model of Change is that gratitude experiences are broadly conceptualized to include not just gratitude emotions, cognitions, and disclosures, but also expressing, receiving, witnessing, and responding to interpersonal gratitude. To this end, gratitude interventions that provide multiple opportunities for social experiences of gratitude (e.g., members expressing gratitude to each other in a group) might offer the greatest promise for fostering durable, positive effects on people’s psychological well-being.

Positive psychological well-being is prospectively associated with superior health outcomes. Positive psychology interventions have promise as a potentially feasible and effective means of increasing well-being and health in those with medical illness, and several initial studies have shown the potential of such programs in medical populations. At the same time, numerous key issues in the existing positive psychology literature must be addressed to ensure that these interventions are optimally effective. These include (1) assessing the nature and scope of PPWB as part of intervention development and application; (2) identifying and utilizing theoretical models that can clearly outline potential mechanisms by which positive psychology interventions may affect health outcomes; (3) determining consistent, realistic targets for positive psychology interventions; (4) developing consistent approaches to the promotion of positive psychological well-being; (5) emphasizing the inclusion of diverse samples in treatment development and testing; and (6) considering implementation and scalability from the start of intervention development to ensure effective real-world application. Attention to these six domains could greatly facilitate the generation of effective, replicable, and easily adopted positive psychology programs for medical populations with the potential to have an important impact on public health.

COVID-19 prompted distress and increased reliance on digital mental health interventions, which previously demonstrated low rates of retention and adherence. This single-arm trial evaluated whether self-guided, web-based, positive affect regulation skills (PARK) were engaging and associated with changes in well-being during the pandemic. Over 6 weeks, PARK delivers brief lessons and practices in skills designed to increase positive emotions: noticing positive events, savoring, gratitude, mindfulness, positive reappraisal, personal strengths, and self-compassion. Patient-Reported Outcome Measurement Information System (PROMIS) computer adaptive tests of anxiety, depression, social isolation, positive affect, and meaning and purpose were administered at baseline, post-intervention, and 6 months after baseline. Retention and usage of PARK were measured by the web-based assessment and intervention platforms. The sample (n = 616) was predominantly female, non-Hispanic, white, and well-educated. Of those who completed baseline, only 42% completed a follow-up assessment; 30% never logged into PARK. Among those who did, 86% used at least one skill, but only 14% completed PARK. Across retention and usage metrics, older age predicted more engagement. In multivariable models, people of color and people with greater baseline anxiety were more likely to complete PARK. All well-being indicators improved over time, with greater improvements in anxiety and social isolation among participants who accessed at least one PARK skill compared to those who did not. Retention and usage rates mirrored pre-pandemic trends, but within this select sample, predictors of engagement differed from prior research. Findings underscore the need for additional efforts to ensure equitable access to digital mental health interventions and research. Trials registration: NCT04367922.

Cognitive reappraisal is perhaps the most researched emotion regulation strategy. It involves reinterpreting emotional content to reduce its impact. While many studies have demonstrated that cognitive reappraisal reduces negative affect, the utility of cognitive reappraisal in buffering against the consequences of negative affect on subsequent behaviors and attitudes is not clear. To address this issue, the present study assessed whether cognitive reappraisal mitigates the influence of immediate threat on food craving. In Experiment 1, 80 women performed a novel combination of a cognitive reappraisal task with a food-rating task. Participants were exposed to threat-provoking or neutral images and were instructed to either reappraise or observe the images. Subsequently, they rated their desire to eat different types of foods. As expected, the desire to eat decreased after exposure to threat-provoking content. However, after reappraising the threat-provoking images, the desire to eat increased relative to when participants merely observed these images. These results were replicated in Experiment 2 (N = 46) which also showed that the effect of reappraisal on the desire to eat was fully mediated by the subjective emotional reactions to the threat-provoking content. These findings show that cognitive reappraisal can modulate links between emotion and food craving by buffering against the consequences of negative affect on basic human processes.

Parental care has attracted attention from both proximate and ultimate perspectives. While understanding the adaptive significance of care has been the focus of work in diverse organisms in behavioral ecology, most of what we know about the proximate mechanisms underlying parental care behavior comes from studies in mammals. Although studies on mammals have greatly improved our understanding of care, viewing parental care solely through a mammalian lens can limit our understanding. Here, we draw upon examples from non-mammalian vertebrate systems to show that in many ways mammals are the exception rather than the rule for caregiving: across vertebrates, maternal care is often not the ancestral or the most common mode of care and fathering is not derivative of mothering. Embracing the diversity of parental care can improve our understanding of both the proximate basis and adaptive significance of parental care and the affective processes involved in caregiving.
