The purpose of the current study was to examine the effects of cognitive behavior therapy (CBT-I) for insomnia on patients with insomnia co-morbid with hearing impairment. A randomized controlled design was used with a 3-month follow-up. Thirty-two patients with insomnia co-morbid with hearing impairment were randomized to either CBT-I or a waitlist condition (WLC). The primary outcome was insomnia severity. Secondary outcomes were sleep diary parameters, dysfunction, anxiety, and depression. Compared to WLC, CBT-I resulted in lower insomnia severity at post-treatment and at follow-up (d = 1.18-1.56). Relative to WLC, CBT-I also led, at both assessment points, to reduced total wake time (d = 1.39) and increased sleep restoration (d = 1.03-1.07) and sleep quality (d = 0.91-1.16). Both groups increased their total sleep time, but no significant group difference emerged. Compared to WLC, CBT-I resulted in higher function (d = 0.81-0.96) and lower anxiety (d = 1.29-1.30) at both assessment points. Neither CBT-I nor WLC led to improvement on depression. Based on the Insomnia Severity Index, more CBT-I (53-77%) than WLC participants (0-7%) were treatment responders. Also, more CBT-I (24%) than WLC participants (0%) remitted. In patients with insomnia co-morbid with hearing impairment, CBT-I was effective in decreasing insomnia severity, subjective sleep parameters, dysfunction, and anxiety. These findings are in line with previous results on the effects of CBT-I in other medical conditions.
本研究旨在探讨认知行为疗法(CBT-I)治疗失眠对合并听力障碍的失眠患者的影响。采用随机对照设计,并进行3个月的随访。32例合并听力障碍的失眠患者被随机分为CBT-I组或等待名单对照组(WLC)。主要结局指标为失眠严重程度。次要结局指标包括睡眠日记参数、功能障碍、焦虑和抑郁。与WLC相比,CBT-I在治疗后及随访时导致更低的失眠严重程度(d=1.18-1.56)。相对于WLC,CBT-I在两个评估点还导致总觉醒时间减少(d=1.39)、睡眠恢复增加(d=1.03-1.07)以及睡眠质量提高(d=0.91-1.16)。两组的总睡眠时间均增加,但未出现显著的组间差异。与WLC相比,CBT-I在两个评估点均导致更高的功能水平(d=0.81-0.96)和更低的焦虑水平(d=1.29-1.30)。CBT-I组和WLC组均未使抑郁症状得到改善。根据失眠严重程度指数,CBT-I组的治疗有效者(53-77%)多于WLC组(0-7%)。此外,CBT-I组的缓解者(24%)多于WLC组(0%)。对于合并听力障碍的失眠患者,CBT-I在降低失眠严重程度、主观睡眠参数、功能障碍和焦虑方面有效。这些发现与之前关于CBT-I在其他医疗状况下疗效的结果一致。
