Cross-Sectional and Longitudinal Associations Between Posttraumatic Stress Symptoms and Hypersexual Behaviors Among Individuals Who have Gambled in Their Lifetimes

Abstract

Abstract Background Exposure to traumatic experiences represent one factor that may contribute to the development of hypersexual behaviors. Aim We investigated the associations between posttraumatic stress symptoms and hypersexual behaviors by analyzing survey data from 2 samples. Method The first sample consisted of n = 585 college students, and the second consisted of n = 786 adults recruited via Amazon's Mechanical Turk (MTurk), n = 337 of whom completed a 6-month follow-up survey. We conducted 3 hierarchical regression analyses adjusting for age, gender, sexual orientation, impulsivity, drug use, alcohol use, and gambling. Outcomes The primary outcomes for this investigation were associations between posttraumatic stress symptoms, measured using the PTSD Checklist for DSM-IV and DSM-5 (PCL-C and PCL-5), and hypersexual behaviors, measured using the Hypersexual Behavior Inventory (HBI). Results A significant regression, R2 = 0.230, R2adjusted = 0.211, F (14,570) = 12.17, P < .001, revealed posttraumatic stress symptoms were associated with hypersexual behaviors in the university student sample (β = 0.154). A significant regression using the MTurk sample, R2 = 0.403, R2adjusted = 0.392, F (14,771) = 37.13, P < .001, confirmed this finding (β = 0.259). In addition, a significant regression, R2 = 0.562, R2adjusted = 0.541, F (15,321) = 27.42, P < .001, indicated that posttraumatic stress symptoms were longitudinally associated with increased hypersexual behaviors (β = .190) after adjusting for all variables, including baseline hypersexuality. Clinical Translation Results suggest that individuals experiencing posttraumatic stress symptoms are at increased risk for current and future hypersexual behaviors. Strengths & Limitations This investigation involved secondary analyses of adults who had gambled at least once in their lives and findings may not generalize to those who have never gambled. Furthermore, longitudinal findings may be impacted by selection bias (42% completion rate) and may not generalize to follow up periods longer than 6-months. Conclusion This study provides support for the hypothesis that posttraumatic stress symptoms are associated with increased hypersexual behavior, and further research is indicated to explore the etiology and directionality of this relationship.
