Aim: This study aims to investigate the prevalence of Post-Traumatic Stress Disorder (PTSD) among survivors of natural disasters, focusing on the occurrence and severity of symptoms using standardized diagnostic tools. Materials and Methods: A cross-sectional design was utilized to assess PTSD prevalence in a sample of 100 participants who survived recent natural disasters, including earthquakes, floods, hurricanes, and wildfires. Data were collected using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) and the PTSD Checklist for DSM-5 (PCL-5). Participants were recruited through community outreach, healthcare facilities, and disaster relief centers, with ethical approval obtained from the Institutional Review Board. Data analysis involved descriptive statistics, chi-square tests, and logistic regression using SPSS version 26.0. Results: The study found that 40% of participants exhibited no PTSD symptoms, while 60% showed varying degrees of severity. Mild PTSD symptoms were reported by 25% of the participants, moderate symptoms by 20%, and severe to extreme symptoms by 15%. The logistic regression analysis indicated that age (30-44 years) and multiple disaster experiences were significant predictors of PTSD, with p-values of 0.03 and 0.001, respectively. Conclusion: The findings suggest that age and the severity of exposure significantly influence the development of PTSD in natural disaster survivors. Targeted mental health interventions should be prioritized for high-risk groups to mitigate the long-term psychological impact of these events.
