The authors investigated the potential effectiveness of biofeedback as a complementary treatment for PTSD.
This exploratory study used heart variability biofeedback and determined its efficacy in treating PTSD through the use of two rating instruments, The Post-traumatic Stress Disorder Checklist (PCL)-Military version and the Zung Self-Rating Depression Scale. Active duty service members deployed to Iraq or Afghanistan were alternatively assigned to a treatment as usual control group and treatment as usual with the addition of biofeedback. The authors administered the two instruments before treatment and at the conclusion of three weeks of biofeedback therapy.
Biofeedback did not produce a measurable improvement. A one way repeated measures analysis of variance (ANOVA) was used to examine change in PCL scores over time. There was a main effect for time, F(1, 36)=11.98, p<.001, indicating a decrease in PCL scores from baseline to three weeks for both the control and treatment group. Results demonstrated a nonsignificant main effect of group, F(1, 36)=.1.79, p=ns, and a nonsignificant group by time interaction, F(1, 36)=.2.59, p=ns. Similarly, for depression, results showed a significant main effect for time, F(1, 33)=10.26, p<.003, indicating a decrease in Zung scores from baseline to three weeks for both the control and treatment group. Results demonstrated a nonsignificant main effect of group, F(1, 33)=.385, p=ns, and a nonsignificant group by time interaction, F(1, 33)=3.52, p=ns.
The addition of biofeedback did not produce a measurable improvement in PTSD or depression scores in this exploratory study.
作者研究了生物反馈作为 PTSD 补充治疗的潜在效果。
本探索性研究使用了心率变异性生物反馈，并通过使用两个评定工具，即创伤后应激障碍检查表（PCL-军事版）和 Zung 自评抑郁量表，来确定其治疗 PTSD 的功效。被部署到伊拉克或阿富汗的现役军人被交替分配到常规治疗对照组和常规治疗加生物反馈组。作者在治疗前和生物反馈治疗三周结束时对这两个工具进行了评估。
生物反馈没有产生可衡量的改善。采用单向重复测量方差分析（ANOVA）来检查 PCL 评分随时间的变化。时间有一个主要效应，F(1,36)=11.98，p<.001，表明对照组和治疗组的 PCL 评分从基线到三周都有所下降。结果表明，组间的主要效应不显著，F(1,36)=.1.79，p=ns，组间时间交互作用不显著，F(1,36)=.2.59，p=ns。同样，对于抑郁，结果显示时间有一个显著的主要效应，F(1,33)=10.26，p<.003，表明对照组和治疗组的 Zung 评分从基线到三周都有所下降。结果表明，组间的主要效应不显著，F(1,33)=.385，p=ns，组间时间交互作用不显著，F(1,33)=3.52，p=ns。
在本探索性研究中，生物反馈的添加并没有对 PTSD 或抑郁评分产生可衡量的改善。
