Prosocial behavior promotes positive emotion during the COVID-19 pandemic.

The COVID-19 pandemic has raised concerns about humans' physical and mental well-being. In response, there has been an urgent "call to action" for psychological interventions that enhance positive emotion and psychological resilience. Prosocial behavior has been shown to effectively promote well-being, but is this strategy effective during a pandemic when ongoing apprehension for personal safety could acutely heighten self-focused concern? In two online preregistered experiments ( N = 1,623) conducted during the early stage of pandemic (April 2020), we examined this question by randomly assigning participants to engage in other- or self-beneficial action. For the first time, we manipulated whether prosocial behavior was related to the source of stress (coronavirus disease 2019 [COVID-19]): Participants purchased COVID-19-related (personal protective equipment, PPE) or COVID-19-unrelated items (food/writing supplies) for themselves or someone else. Consistent with preregistered hypotheses, prosocial (vs. non-pro-social or proself) behavior led to higher levels of self-reported positive affect, empathy, and social connectedness. Notably, we also found that psychological benefits were larger when generous acts were unrelated to COVID-19 (vs. related to COVID-19). When prosocial and proself spending involved identical COVID-19 PPEs items, prosocial behavior's benefits were detectable only on empathy and social connectedness, but not on posttask positive affect. These findings suggest that while there are boundary conditions to be considered, generous action offers one strategy to bolster well-being during the pandemic.
