A randomized trial was performed in which imaginal exposure (IE) and cognitive therapy (CT) were compared in the treatment of chronic posttraumatic stress disorder (PTSD). Patients who continued to meet PTSD caseness at the end of a 4-week symptom-monitoring baseline period (n = 72) were randomly allocated to either IE or CT. There was a significant improvement in all measures over treatment and at follow-up, although there were no significant differences between the 2 treatments at any assessment. A significantly greater number of patients who showed worsening over treatment received IE, although this effect was not found at follow-up. Patients who worsened showed a greater tendency to miss treatment sessions, rated therapy as less credible, and were rated as less motivated by the therapist. It was concluded that either exposure or a challenge to cognition can result in symptom reduction, although neither resulted in complete improvement.
进行了一项随机试验，比较了意象暴露疗法（IE）和认知疗法（CT）对慢性创伤后应激障碍（PTSD）的治疗效果。在为期4周的症状监测基线期结束时仍符合PTSD诊断标准的患者（n = 72）被随机分配至IE组或CT组。在治疗期间及随访时，所有测量指标均有显著改善，尽管在任何评估中两种治疗方法之间均无显著差异。治疗期间症状恶化的患者中，接受IE治疗的人数显著更多，尽管在随访时未发现此效应。症状恶化的患者错过治疗疗程的倾向更大，认为治疗可信度更低，且被治疗师评定为动机更低。研究得出结论，暴露疗法或认知挑战均可导致症状减轻，尽管两者均未带来完全改善。
