The efficacy of digital brief behavioural treatment for insomnia using a smartphone application in conjunction with light therapy was investigated in university students who had insomnia symptoms with late chronotypes. In this two-arm parallel randomized-controlled trial, participants with insomnia symptoms and late chronotypes were recruited between October and November 2023. The duration of the intervention program was 4 weeks. The smartphone application provides digital brief behavioural treatment for insomnia, including programs for advanced phases. The intervention group used blue-light-emitting diode glasses in the morning after waking up for 2-4 weeks. The primary outcome was a change in the Insomnia Severity Index during the study period. The Insomnia Severity Index was obtained weekly using a web questionnaire. Of the 28 students, 14 each were assigned to the intervention and control groups. The mean Insomnia Severity Index scores at baseline were 12.2 and 12.5; after 4 weeks, they declined to 7.2 and 10.6 in the intervention and control groups, respectively. Primary analysis using a linear mixed model showed a significant improvement in the temporal trends of the Insomnia Severity Index in the intervention group (p < 0.001). The scores on the Morningness-Eveningness Questionnaire (p = 0.008) and RU-SATED (p = 0.005) significantly improved in the intervention group relative to the control group following the intervention. This study demonstrated the effectiveness of the digital brief behavioural treatment for insomnia with light therapy in participants with both insomnia symptoms and late chronotypes.
在患有失眠症状且昼夜节律类型较晚的大学生中，研究了使用智能手机应用程序结合光疗法进行数字简短行为治疗失眠的疗效。在这项双臂平行随机对照试验中，于2023年10月至11月招募了有失眠症状且昼夜节律类型较晚的参与者。干预计划为期4周。该智能手机应用程序提供失眠的数字简短行为治疗，包括高级阶段的程序。干预组在醒来后的早晨使用蓝光发光二极管眼镜，持续2至4周。主要结局是研究期间失眠严重程度指数的变化。使用网络问卷每周获取失眠严重程度指数。28名学生中，每组14人分别被分配到干预组和对照组。基线时失眠严重程度指数的平均得分分别为12.2和12.5；4周后，干预组和对照组分别降至7.2和10.6。使用线性混合模型的初步分析显示，干预组失眠严重程度指数的时间趋势有显著改善（p < 0.）。干预后，干预组在晨型-夜型问卷（p = 0.008）和RU-SATED（p = 0.005）上的得分相对于对照组有显著改善。这项研究证明了数字简短行为治疗结合光疗法对既有失眠症状又有较晚昼夜节律类型的参与者治疗失眠的有效性。
