Objective: Cognitive therapy (CT) and behavior therapy (BT) are both effective for insomnia but are expected to work via different pathways. Empirically, little is known about their symptom-specific effects. Method: This was a secondary analysis of a randomized controlled trial of online treatment for insomnia disorder (N = 219, 72.9% female, mean age = 52.5 years, SD = 13.9). Participants were randomized to CT (n = 72), BT (n = 73), or wait-list (n = 74). Network Intervention Analysis was used to investigate the symptom-specific treatment effects of CT and BT throughout treatment (wait-list was excluded from the current study). The networks included the Insomnia Severity Index items and the sleep diary-based sleep efficiency and were estimated biweekly from Week 0 until Week 10. Results: Participants in the BT condition showed symptom-specific effects compared to CT on "sleep efficiency" (Week 4-8, post-test), "difficulty maintaining sleep" (Week 4), and "dissatisfaction with sleep" (post-test). Participants in the CT showed symptom-specific effects compared to BT on "interference with daily functioning" (Week 8, post-test), "difficulty initiating sleep", "early morning awakenings," and "worry about sleep" (all post-test). Conclusions: This is the first study that observed specific differential treatment effects for BT and CT throughout the course of their treatment. These effects were more pronounced for BT than for CT and were in line with the theoretical background of these treatments. We think the embedment of the theoretical background of CT and BT in empirical data is of major importance to guide further treatment development.

认知疗法和行为疗法对失眠的症状特异性影响:网络干预分析。

目的:认知疗法 (CT) 和行为疗法 (BT) 对失眠症均有效,但预计通过不同途径发挥作用。从经验上讲,对它们的症状特异性影响知之甚少。方法:这是对失眠障碍在线治疗随机对照试验的二次分析(N = 219,72.9% 女性,平均年龄 = 52.5 岁,SD = 13.9)。参与者被随机分配到 CT (n = 72)、BT (n = 73) 或等待名单 (n = 74)。网络干预分析用于研究 CT 和 BT 在整个治疗过程中的症状特异性治疗效果(当前研究排除了等待名单)。这些网络包括失眠严重程度指数项目和基于睡眠日记的睡眠效率,并且从第 0 周到第 10 周每两周估计一次。 结果:与 CT 相比,BT 条件下的参与者在“睡眠效率”(第 4-8 周,测试后)、“难以维持睡眠”(第 4 周)和“对睡眠不满意”(测试后)方面表现出特定的症状影响. 与 BT 相比,CT 参与者在“干扰日常功能”(第 8 周,测试后)、“难以入睡”、“清晨醒来”和“担心睡眠”(所有测试后)方面表现出症状特异性影响。测试)。结论:这是第一项在整个治疗过程中观察到 BT 和 CT 的特定差异治疗效果的研究。BT 的这些效果比 CT 更明显,并且与这些治疗的理论背景一致。我们认为将 CT 和 BT 的理论背景嵌入经验数据中对于指导进一步的治疗发展具有重要意义。(PsycInfo 数据库记录 (c) 2021 APA,保留所有权利)。
