ABSTRACT

Objective To investigate the positive detectable rate of post-traumatic stress disorder ( PTSD ) and its influencing factors among the military rescuers , and explore preventive measures for rescuers .Method At three points , 2600 soldiers from Wenchuan military rescuers were enrolled , whose PTSD symptoms were evaluated by PCL-S.Self-edited questionnaires on the general state , Alerting Test Questionnaires for Military Group Stress ( ATQMGS ) , and State-Trait Anxiety Inventory(STAI)were used to evaluate the influencing factors of rescuers′PTSD symptoms.Results Seventy-one rescuers were tested positive for PTSD and the positive detectable rate was 2.9%.On the basis of demographic data , the difference test suggested that rescuers different in terms of positions , duration of rescue, family structure, trauma history, mental problem history or trauma history during the rescue were significantly differenct in PTSD symptoms , which were strongly and positively correlated with anxiety , morale, and self-efficacy, but were strongly and negatively correlated with leadership support , control feeling , promotion motivation , cognition of tasks , sense of belonging and work value .Multiple linear regression showed that the influencing factors of PTSD symptoms included the trait of anxiety , leadership support , trauma history, control feeling, mental problem history, trauma history during the rescue, position and duration of rescue. Conclusion The PTSD positive detectable rates among the military rescuers are lower than in the previous research.PTSD symptoms of military rescuers are related to such factors as the position , duration of rescue , family structure , trauma histo ry, mental problem history, trauma history during the rescue, trait of anxiety, morale, self -efficacy, leadership support, control feeling , promotion motivation , cognition of tasks , sense of belonging and work value .The influencing factors of PTSD symptoms are the trait of anxiety , leadership support, trauma history, control feeling, mental problem history, trau-ma history during the rescue , position level and rescue duration .
