Cognitive behavioral therapy for insomnia (CBT-I) is a treatment with moderate to large effects. These effects are believed to be sustained long-term, but no systematic meta-analyses of recent evidence exist. In this present meta-analysis, we investigate long-term effects in 30 randomized controlled trials (RCTs) comparing CBT-I to non-active control groups. The primary analyses (n = 29 after excluding one study which was an outlier) showed that CBT-I is effective at 3-, 6- and 12-mo compared to non-active controls: Hedges g for Insomnia severity index: 0.64 (3 m), 0.40 (6 m) and 0.25 (12 m); sleep onset latency: 0.38 (3 m), 0.29 (6 m) and 0.40 (12 m); sleep efficiency: 0.51 (3 m), 0.32 (6 m) and 0.35 (12 m). We demonstrate that although effects decline over time, CBT-I produces clinically significant effects that last up to a year after therapy.
失眠的认知行为疗法(CBT-I)是一种具有中等至较大效果的治疗方法。这些效果被认为是长期持续的,但目前还没有对最近证据进行系统的荟萃分析。在本次荟萃分析中,我们调查了 30 项随机对照试验(RCT)中 CBT-I 与非活动对照组的长期效果。主要分析(排除一项异常研究后 n=29)表明,与非活动对照组相比,CBT-I 在 3、6 和 12 个月时有效:失眠严重指数的 Hedges g:0.64(3 个月),0.40(6 个月)和 0.25(12 个月);入睡潜伏期:0.38(3 个月),0.29(6 个月)和 0.40(12 个月);睡眠效率:0.51(3 个月),0.32(6 个月)和 0.35(12 个月)。我们证明,尽管效果随时间下降,但 CBT-I 产生的临床显著效果可在治疗后持续长达一年。
