Abstract

Background: Attentional bias is a salient manifestation of insomnia. Digital cognitive therapy for insomnia (dCBT-I) has been validated as effective in alleviating this cognitive dysfunction. However, the effect of dCBT-I on attentional bias among Chinese individuals with insomnia remains undiscussed. This research sought to investigate this effect via a pictorial dot-probe task.

Methods: In Study 1, the pattern of attentional bias among poor sleepers (N = 52) and normal sleepers (N = 56) was assessed by the dot-probe task. In study 2, dCBT-I and conventional education were received by the experimental group (N = 42) and control group (N = 25), respectively. The dot-probe tasks and sleep quality assessments were completed at baseline and post-test.

Results: The results of Study 1 indicated that poor sleepers exhibited significant attentional bias, characterized by increased attentional vigilance. Compared to normal sleepers, they showed heightened attentional vigilance toward sleep-related cues. The results of Study 2 showed that both dCBT-I and conventional education led to improvements in PSQI scores. However, only dCBT-I training alleviated attentional vigilance toward sleep-related cues. Additionally, dCBT-I was uniquely effective in reducing feelings of fatigue.

Conclusions: Poor sleepers had a significant attentional bias, marked by heightened vigilance toward sleep-related cues. Digital CBT-I effectively reduced attentional vigilance and fatigue, suggesting that dCBT-I targets the cognitive distortions associated with insomnia.

数字化 CBT 干预对有失眠症状的睡眠质量差者的注意偏差和睡眠质量的影响。

背景：注意偏差是失眠症的一种突出表现。失眠症数字认知疗法（dCBT-I）已被证实能有效缓解这种认知功能障碍。然而，dCBT-I 对中国失眠患者注意偏差的影响仍未得到讨论。本研究试图通过图形点探测任务来研究这种影响：在研究1中，睡眠质量差者（52人）和睡眠正常者（56人）的注意偏差模式通过点探测任务进行了评估。在研究 2 中，实验组（42 人）和对照组（25 人）分别接受了 dCBT-I 和传统教育。实验组和对照组分别接受了 dCBT-I 和传统教育，并在基线和测试后完成了点探测任务和睡眠质量评估：研究 1 的结果表明，睡眠质量差的人表现出明显的注意力偏差，其特点是注意力警觉性增加。与正常睡眠者相比，他们对睡眠相关线索的注意警觉性更高。研究 2 的结果显示，dCBT-I 和传统教育都能改善 PSQI 分数。然而，只有dCBT-I训练缓解了对睡眠相关线索的注意警觉。此外，dCBT-I 在减少疲劳感方面也有独特的效果：结论：睡眠质量差的人有明显的注意力偏差，表现为对睡眠相关线索的警觉性增高。数字CBT-I有效降低了注意力警觉性和疲劳感，表明dCBT-I针对的是与失眠相关的认知扭曲：ChiCTR2100053172（注册日期：2021年11月13日）。
