Coming out is both one of the most vital and challenging life events for lesbian, gay, and bisexual (LGB) individuals looking to live authentically (Bonet et al., 2007; Grafsky, 2017; Harrison, 2003; Savin-Williams, 2001). Depending on the individual’s coping, those who suffer a traumatic coming out experience may also have experience psychological growth (Cox et al, 2010; Solomon et al., 2015; Vaughan, 2007). One factor that may facilitate growth is the parenting received in childhood. Objective: The aim of this study was to explore the predictive role of Strengths-Based Parenting on Post-Traumatic Stress Symptoms and Post-Traumatic Growth in LGB individuals in Lima, Peru, after coming out. For this purpose, the Post-Traumatic Growth Inventory (PTGI; Tedeschi & Calhoun, 1996), the Post-Traumatic Stress Disorder Checklist for the DSM-5 (PCL-5; Weathers, Litz, Keane, Palmieri, Marx & Schnurr, 2013), and the Strengths-Based Parenting Questionnaire (SBPQ; Waters, 2017) were translated, adapted, and analyzed psychometrically. Method: 300 participants completed the PTGI, PCL-5, and SBPQ. Correlation and hierarchical regression analyses were performed. Results and discussion: Being female, and having a partner predicted PTG. Moreover, SBP predicted PTG, and even more strongly with higher PTSS levels. This relationship remained even after controlling for sociodemographic variables.
