Examining the Five-Factor Personality Model: A Latent Profile Analysis in Individuals with Above Threshold PTSD Symptomology
Disciplines

Abstract (300 words maximum)
Latent Profile Analysis (LPA) has been extensively used in psychological research to uncover distinct subgroups within heterogeneous populations. Historically, these subgroups have been pivotal for understanding the nuanced differences in symptom presentations, especially in conditions like PTSD. In this context, individuals with PTSD can vary in their expressed personality traits, which can impact treatment outcomes. This study aimed to understand these variations within a population exhibiting above-threshold PTSD symptomology. Similar to previous literature, LPA revealed three distinct profiles: 'Adaptive', 'Highly Adaptive', and 'Maladaptive'. These profiles were derived from the five-factor personality dimensions: openness, conscientiousness, extraversion, agreeableness, and emotional instability. Follow-up ANOVA outcomes showed significant differences across these profiles in multiple variables, including PTSD severity, resilience, and quality of life measures. Notably, the 'Maladaptive' group showed heightened PTSD symptomology and reduced quality of life, highlighting the importance of personalized therapeutic strategies. Building on previous literature, these findings underscore the necessity of tailoring treatments based on personality profiles, which may lead to improved therapeutic outcomes for individuals who struggle with PTSD.
