Abstract:
Objective To investigate the risk factors associated with post-traumatic stress disorder (PTSD) among fire and rescue personnel and to propose corresponding intervention strategies.
Methods In 2024, a cross-sectional study was conducted using a cluster sampling method in a specific detachment of the Zhejiang Provincial Fire and Rescue Corps. A total of 938 fire and rescue personnel were surveyed using a general information questionnaire, the PTSD Checklist-Civilian Version (PCL-C), and the Social Support Rating Scale (SSRS). A multiple linear regression model was employed to analyze the influencing factors of PTSD.
Results A total of 854 valid questionnaires were returned, with a valid response rate of 91.0%. Among these 854 participants, 18(2.1%) were screened as positive for PTSD (PCL-C total score>37 points). The mean total PCL-C score was(20.05 ± 6.18) points. The mean scores for each dimension were as follows: re-experiencing (5.81 ± 1.78) points, avoidance and numbing (7.99 ± 2.51) points, and hyperarousal (6.26 ± 2.60) points. The multiple linear regression model results indicated that compared to personnel reporting no pain, personnel reporting pain in one site and in multiple sites had PTSD scores higher by 2.078 points and 5.104 points, respectively (both P < 0.05). Personnel previously participating in security duty tasks had scores 1.099 points higher than those not participating (P < 0.05). Those injured during previous emergency responses scored 2.887 points higher than those not being injured (P < 0.05). Compared to individuals with low social support, those with moderate or high support had PTSD scores lower by 2.045 points and 2.219 points, respectively (both P < 0.05).
Conclusions The prevalence of PTSD in this fire detachment in Zhejiang Province was relatively low. The occurrence of PTSD among fire and rescue personnel was closely associated with multiple factors. Comprehensive intervention strategies, such as mental health education and enhancement of social support, should be formulated based on practical situations to safeguard the psychological well-being of these personnel.
