Acute stress disorder permits an early identification of trauma survivors who are at risk of developing chronic posttraumatic stress disorder (PTSD). This study aimed to prevent PTSD by an early provision of cognitive behavior therapy. Specifically, this study indexed the relative efficacy of prolonged exposure and anxiety management in the treatment of acute stress disorder.
Forty-five civilian trauma survivors with acute stress disorder were given five sessions of 1) prolonged exposure (N = 14), 2) a combination of prolonged exposure and anxiety management (N = 15), or 3) supportive counseling (N = 16) within 2 weeks of their trauma. Forty-one trauma survivors were assessed at the 6-month follow-up.
Fewer patients with prolonged exposure (14%, N = 2 of 14) and prolonged exposure plus anxiety management (20%, N = 3 of 15) than supportive counseling (56%, N = 9 of 16) met the criteria for PTSD after treatment. There were also fewer cases of PTSD in the prolonged exposure group (15%, N = 2 of 13) and the prolonged exposure plus anxiety management group (23%, N = 3 of 13) than in the supportive counseling group (67%, N = 10 of 15) 6 months after the trauma. Chronic PTSD in the supportive counseling condition was characterized by greater avoidance behaviors than in the prolonged exposure condition or the prolonged exposure plus anxiety management condition.
These findings suggest that PTSD can be effectively prevented with an early provision of cognitive behavior therapy and that prolonged exposure may be the most critical component in the treatment of acute stress disorder.
急性应激障碍有助于早期识别有发展为慢性创伤后应激障碍(PTSD)风险的创伤幸存者。本研究旨在通过早期提供认知行为疗法来预防PTSD。具体而言,本研究对延长暴露疗法和焦虑管理疗法在治疗急性应激障碍中的相对疗效进行了评估。
45名患有急性应激障碍的平民创伤幸存者在创伤后2周内接受了5次治疗,分别为:1)延长暴露疗法(N = 14);2)延长暴露疗法与焦虑管理疗法相结合(N = 15);或3)支持性咨询(N = 16)。41名创伤幸存者在6个月随访时接受了评估。
治疗后,与接受支持性咨询的患者(56%,16人中9人)相比,接受延长暴露疗法的患者(14%,14人中2人)和接受延长暴露疗法加焦虑管理疗法的患者(20%,15人中3人)符合PTSD标准的人数更少。创伤后6个月时,延长暴露疗法组(15%,13人中2人)和延长暴露疗法加焦虑管理疗法组(23%,13人中3人)的PTSD病例数也少于支持性咨询组(67%,15人中10人)。支持性咨询组的慢性PTSD患者比延长暴露疗法组或延长暴露疗法加焦虑管理疗法组的患者有更多的回避行为。
这些研究结果表明,早期提供认知行为疗法可有效预防PTSD,延长暴露疗法可能是治疗急性应激障碍的最关键组成部分。
