The present study investigated the role of emotional self-regulation about social support and psychological well-being in health care workers in the COVID‐۱۹ pandemic. This was a descriptive-analytical study followed by a correlational design. This cross-sectional research was conducted on HCWs (medical, nursing, and volunteer COVID-۱۹ workers) who worked in hospitals or clinic centers in Tehran, Iran from May–to August ۲۰۲۰. A total of ۱۴۶ HCWs were selected using the random method. Research instruments included the Demographic information questionnaire, The Emotional Self-Regulation Inventory (SRI), the Multidimensional Scale of Perceived Social Support (MSPSS), AND The Ryff's scale of Psychological well-being, short-form (۱۸-item). The collected data were analyzed using the Pearson correlation coefficient and the path analysis technique in SPSS (version ۲۵) and SmartPLS (version ۲) software. The bootstrapping test findings showed the direct effect of social support on psychological well-being was statistically confirmed (b =۰.۴۰, t=۲.۴۴) and the indirect effect or the full mediator effect of emotional self-regulation in the relationship between social support on psychological well-being was found to be significant (b =۰.۲۵, t=۲.۹۴). Thus, the full mediator role of emotional self-regulation in the relationship between social support on psychological well-being has been proven. The total effect of social support on psychological well-being was confirmed (b =۰.۶۵, t=۲.۷۹). These findings contribute to behavioral science knowledge and understanding of emotion regulation in enhancing social support and well-being during this pandemic and beyond.
