Bereaved individuals often experience sleep problems. The aim of this study was to evaluate feasibility and preliminary effects of internet-delivered cognitive behavioral therapy for insomnia (iCBT-i) in bereaved parents. Parents were randomized to iCBT-i (n = 10) or an active control group (n = 11). Primary outcome (insomnia) and secondary outcomes (prolonged grief, depression, posttraumatic stress, and grief rumination) were assessed pre- and post-treatment, with 9- and 18-month follow-ups. Feasibility was assessed post-treatment and one month later. Most parents reported positive effects of the treatment. The intervention group improved significantly from pre- to post-treatment and had a significantly larger reduction of insomnia when analyzed over all four time-points (Wald χ² = 30.0, p < 0.001), although the effect at post-treatment was very small (d = 0.1) for insomnia. Thus, iCBT-i was feasible and was related to reduced insomnia and psychological distress in bereaved parents, both short- and long-term, but the results regarding the treatment effect are preliminary due to the small sample size.

失去亲人的人经常会遇到睡眠问题。本研究的目的是评估互联网提供的认知行为疗法对失去亲人的父母失眠 (iCBT-i) 的可行性和初步效果。父母被随机分配到 iCBT-i（n = 10）或主动对照组（n = 11）。主要结局（失眠）和次要结局（长期悲伤、抑郁、创伤后压力和悲伤沉思）在治疗前后进行评估，并进行了 9 个月和 18 个月的随访。在治疗后和 1 个月后评估了可行性。大多数父母报告了治疗的积极效果。在所有四个时间点进行分析时，干预组从治疗前到治疗后都有显着改善，并且失眠的减少显着更大（Wald χ ²  = 30.0，p < 0.001)，尽管治疗后 对失眠的影响非常小 ( d = 0.1)。因此，iCBT-i 是可行的，并且与减少失去亲人的父母的失眠和心理困扰有关，无论是短期还是长期，但由于样本量小，关于治疗效果的结果是初步的。
