Abstract

Introduction: Insomnia and depression are highly prevalent disorders and commonly occur together. Cognitive behavioral therapy for insomnia, CBT-I, has been shown to be effective in treating insomnia and also comorbid depression. However, it is unclear whether effects of CBT-I on depression are specific or nonspecific. Also, depressive symptoms often remain too high after CBT-I, indicating a need for improved treatments. The objective was to determine whether combining CBT-I with CBT for depression, without increasing treatment length, reduces both insomnia and depression more than CBT for depression with a placebo insomnia intervention.

Methods: A 12-week double-blind randomized controlled trial with a 6-month follow-up in a psychiatric setting using therapist-guided internet-delivered treatments was conducted. Patients (N = 126) were diagnosed with insomnia disorder and major depression by physicians. Primary outcome measures were as follows: self-rating scales Insomnia Severity Index (ISI) and Montgomery-Åsberg Depression Rating Scale (MADRS-S).

Results: The combined treatment showed specific effects on insomnia severity over the control treatment (p = 0.007) but was not more effective in reducing depression severity. Within-group effects (Cohen's d) at post and at 6 months were as follows: ISI 1.40 and 1.42 (combined treatment), 0.95 and 1.00 (control); MADRS-S 0.97 and 1.12 (combined), 0.88 and 0.89 (control).

Conclusions: CBT-I shows large specific effects on insomnia severity and is superior to control in this regard. Both treatments had similar effects on depression severity, i.e., combining CBT-I with CBT for depression did not enhance outcomes on depression compared to control. We suggest CBT-I should always be offered to patients with insomnia and depression comorbidity, possibly as the first-hand choice. Combining it with a psychological treatment for depression could be too burdening and may not be beneficial.

失眠与抑郁并发症的心理治疗：双盲随机安慰剂对照试验》。

简介失眠和抑郁是高发疾病，通常同时出现。治疗失眠的认知行为疗法（CBT-I）已被证明对治疗失眠和合并抑郁症有效。然而，目前还不清楚 CBT-I 对抑郁症的影响是特异性的还是非特异性的。此外，CBT-I 治疗后抑郁症状往往仍然过高，这表明需要改进治疗方法。本研究旨在确定在不增加治疗时间的情况下，将 CBT-I 与治疗抑郁症的 CBT 相结合，是否比治疗抑郁症的 CBT 加上安慰剂失眠干预更能减少失眠和抑郁症：方法：在精神病院开展了一项为期 12 周、随访 6 个月的双盲随机对照试验，采用治疗师指导的互联网治疗方法。患者（N = 126）被医生诊断为失眠症和重度抑郁症。主要结果指标如下：失眠严重程度自评量表（ISI）和蒙哥马利-阿斯伯格抑郁评分量表（MADRS-S）：结果：与对照组相比，联合治疗对失眠严重程度有特殊效果（p = 0.007），但在降低抑郁严重程度方面并不更有效。治疗后和 6 个月时的组内效应（Cohen's d）如下：ISI分别为1.40和1.42（联合治疗），0.95和1.00（对照组）；MADRS-S分别为0.97和1.12（联合治疗），0.88和0.89（对照组）：结论：CBT-I 对失眠严重程度有很大的特效，在这方面优于对照组。两种治疗方法对抑郁症严重程度的影响相似，即与对照组相比，将 CBT-I 与治疗抑郁症的 CBT 相结合并不能提高抑郁症的治疗效果。我们建议，CBT-I 应始终提供给失眠和抑郁并发症患者，并可能作为第一选择。将 CBT-I 与抑郁症的心理治疗相结合可能会造成过重的负担，而且可能不会带来益处。
