Perceived Spiritual Support Counteracts the Traumatic Impact of Extreme Disasters: Exploration of Moderators

Introduction: Extreme disasters have increased exponentially in recent years and result in threats and traumatic reactions in communities globally. Humans turn to their existential relations for survival following disasters; yet, religion and spirituality (R/S) remains underinvestigated in disaster contexts, with most studies measuring general R/S concepts in Christian samples. To address the resulting gap, this study sought to (a) establish short form, disaster-specific scales of perceived spiritual support (PSS); (b) test the factor’s relationships with mental health outcomes; and (c) explore moderators of those relationships. Method: With strong community engagement, a culturally diverse sample (N = 566) completed an online survey after Hurricanes Maria and Michael (H-MM). Multivariate analyses established psychometric properties for 2 PSS short-form scales (PSSS-S1 and -S2) and revealed associations between and moderators of (disaster-related experiences and character strengths) the scales and 2 traumatic outcomes: posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG). Results: PSSS-S1 and -S2 demonstrated adequate reliability and validity. PSS was associated inversely with PTSD symptoms at a marginal level but positively and strongly with PTG. Character strengths moderated the link of PSS to PTSD but not PTG. Most disaster-related factors were associated with both outcomes. Conclusions: The findings highlight the function of PSS in survival. PSSS-S1 and -S2 are adequate measures for rapid and cross-cultural data collection in extreme disasters.
