To examine the effects of online Cognitive Behavior Therapy for Insomnia (CBTI) on adolescents' sleep and cognitive functioning.
32 adolescents (13-19 years, M = 15.9, SD = 1.6) with DSM-5 insomnia disorder, were randomly assigned to a treatment group (n = 18) or a waiting list (n = 14). Treatment consisted of six guided self-help online CBTI sessions. Both groups were assessed at baseline and post-treatment. Sleep was measured with actigraphy, sleep logs, and questionnaires. Cognitive functioning was assessed with a battery of standard cognitive tests.
After CBTI the treatment group showed significant improvements compared to the waiting list group in sleep efficiency from actigraphy and sleep logs. This finding was confirmed by improvements in other sleep variables from sleep logs, and in symptoms of chronic sleep reduction and insomnia. Most participants from the treatment group improved to sub clinical levels of insomnia. Cognitive functioning of the treatment group showed more improvement compared to the waiting list in visuospatial processing, selective attention and phonological working memory, and a trend of improvement in response inhibition and set shifting, letter fluency and sustained attention, but not in declarative memory, visuospatial working memory, category fluency, and general cognitive speed. Changes in sleep appeared to be related to changes in cognitive functioning.
These results indicate that CBTI can have positive effects on cognitive functions in adolescents, with notable improvements in visuospatial processing and phonological working memory but not in visuospatial working memory.
探讨在线认知行为疗法治疗失眠（CBTI）对青少年睡眠和认知功能的影响。
32名患有DSM-5失眠症的青少年（13 - 19岁，M = 15.9，SD = 1.6）被随机分为治疗组（n = 18）或等待列表组（n = 14）。治疗包括六个在线引导自助CBTI疗程。两组在基线和治疗后均进行评估。通过活动记录仪、睡眠日志和问卷测量睡眠情况。使用一系列标准认知测试评估认知功能。
与等待列表组相比，CBTI治疗后治疗组在活动记录仪和睡眠日志记录的睡眠效率方面有显著改善。睡眠日志中其他睡眠变量的改善以及慢性睡眠减少和失眠症状的改善证实了这一发现。治疗组的大多数参与者失眠症状改善到亚临床水平。与等待列表组相比，治疗组在视觉空间处理、选择性注意和语音工作记忆方面的认知功能有更多改善，在反应抑制和定势转换、字母流畅性和持续注意方面有改善趋势，但在陈述性记忆、视觉空间工作记忆、类别流畅性和一般认知速度方面没有改善。睡眠变化似乎与认知功能变化有关。
这些结果表明，CBTI对青少年的认知功能有积极影响，在视觉空间处理和语音工作记忆方面有显著改善，但在视觉空间工作记忆方面没有改善。
