我们进行了一项随机对照试验，比较认知和行为治疗 (CBT)、支持性心理治疗 (SUPPORT) 或仅评估等待名单 (WAITLIST) 对照的组合。为了研究 PTSD 的心理生理反应，我们测量了参与者在每次治疗之前和之后对幸存的机动车事故 (MVA) 的特殊录音描述的心率 (HR) 反应。结果显示，接受 CBT 的患者 (n = 25) 的 HR 反应性比接受 SUPPORT (n = 26) 或 WAITLIST (n = 22) 的患者显着降低。后两个条件没有区别。所有组中 CAPS 评分的变化与 HR 反应性崩溃的变化之间存在显着但低水平的相关性。
We have conducted a randomized, controlled trial comparing a combination of cognitive and behavioral treatments (CBT), supportive psychotherapy (SUPPORT), or an assessment-only wait-list (WAITLIST) control. To study psychophysiological reactivity in PTSD we measured heart rate (HR) reactivity to idiosyncratic audiotaped descriptions of the motor vehicle accident (MVA) that the participants had survived, both before and after each of the treatments. Results showed significantly greater reduction in HR reactivity for those receiving CBT (n = 25) than for either those in SUPPORT (n = 26) or WAITLIST (n = 22). The latter two conditions did not differ. There were significant but low-level correlations between changes in CAPS scores and changes in HR reactivity collapsing across all groups.
