The COVID-19 pandemic has affected all areas of life, with severe potential consequences for people's mental health. Posttraumatic growth (PTG), a positive psychological change that may develop following a traumatic event, in light of the COVID-19 pandemic has only received little attention. The current study aimed to investigate (1) the prevalence of PTG within the context of the COVID-19 pandemic and (2) which psychological aspects predict COVID-19 pandemic-related PTG using a 1-year longitudinal design. A sample of 70 participants completed a survey on COVID-19, posttraumatic stress, emotional well-being, coping styles, determinates of resilience, and PTG at both T1, May 2020, and T2, May 2021. Results reveal moderate levels of PTG for about one in five participants at both T1 and T2 (21% and 23%, respectively). Moreover, PTG at T1 and T2 were moderate to strongly, positively correlated, r = 0.62. Posttraumatic stress and social support were found to positively predict PTG at T1, while positive affect and social skills were found to positively predict PTG at both T1 and T2, βs = 0.22-.52. Implications of the current findings and suggestions for future research are discussed.
