Psychosocial correlates of posttraumatic growth among U.S. young adults during the COVID-19 pandemic

•Young adults reported low posttraumatic growth scores during the pandemic.•Resilience, family connectedness and distress tolerance predicted growth.•PTSD symptoms and COVID-19 worry predicted posttraumatic growth.•Asian Americans were less likely to report posttraumatic growth.•These factors may help to prioritize screening and supportive treatment. Given the prolonged nature of the COVID-19 pandemic, the purpose of this study was to examine the association between posttraumatic growth (PTG) among young adults during the COVID-19 pandemic and their psychosocial characteristics, specifically: distress tolerance; resilience; family connectedness; depression, anxiety, and PTSD symptoms; and COVID-19-related worry. The study utilized data from 805 U.S. young adults (18–30 years) who completed online surveys during the COVID-19 pandemic across two waves (April-August 2020 and September 2020-March 2021). Overall, young adults reported low PTG scores. PTSD symptoms and COVID-19-related worry significantly predicted higher levels of PTG, while their depression symptoms predicted lower levels of PTG. Resilience and family connectedness significantly predicted higher levels of PTG, and distress tolerance significantly predicted lower levels of PTG after accounting for sociodemographic characteristics and negative influential factors. Compared to Whites, Asians were less likely to report PTG. In general, young adults have not perceived personal growth from the pandemic; however, young adults with certain psychosocial factors appear to be predisposed to such PTG. This study highlights the importance of exploring and elucidating the potential positive trajectories following the adversity of the COVID-19 pandemic.
