Objective: The present study examined the role of posttraumatic stress symptoms (PTSS), strengthbased parenting (SBP), and event exposure on posttraumatic growth (PTG) in Peruvian flood survivors. Method: After contacting local authorities, 1,077 adult participants were surveyed 1 year after the flood. Correlation, moderation, and mediation analyses were conducted to determine relationships between variables. Results: Flood survivors experienced both PTSS and PTG. Additionally, event exposure directly facilitated PTG. Further, SBP influenced PTG both directly and by its role in reducing PTSS. Finally, higher levels of SBP aided individuals in converting PTSS into PTG. Conclusions: Favorable psychological outcomes following floods are not uncommon even for those with high levels of stress or exposure. Individual and community-level interventions should leverage facilitating factors such as SBP to promote growth outcomes such as PTG.
