Experiencing positive emotions is paramount to derive vitality from daily lived experiences. Positive emotions are associated with a range of beneficial outcomes, including longevity, reduced incidents of stroke, improved sleep quality, larger social networks, increased prosocial behavior, lower cortisol levels, and increased endogenous opioids and oxytocin. Despite these benefits, only limited research has focused on understanding positive emotion regulation within the context of depression. Rather, mechanisms related to the regulation of negative emotion have been the focus of research and evidence-based treatments. This interdisciplinary review article aims to advance knowledge regarding the role of positive emotion regulation in individuals with depression to inform the development of transdiagnostic evidenced-based approaches to treatment that bolster the experience of positive life events. We drew on research findings across the fields of clinical psychology, affective science, and social psychology to identify future directions for novel interdisciplinary translational research regarding mechanisms associated with positive emotion regulation.
