Comparative efficacy of different components of cognitive behavioral therapy for insomnia on work productivity: A systematic review and meta-analysis

Insomnia is linked to absenteeism, reduced productivity, and diminished job satisfaction. This study aimed to evaluate the comparative efficacy of different components of Cognitive Behavioral Therapy for Insomnia (CBT-I) on work productivity. PubMed, Cochrane Library, Web of Science Core Collection, MEDLINE, APA PsycINFO, APA PsycArticles, Embase, Wan Fang, and CNKI were searched from inception to October 8, 2024. Evidence quality was assessed using the GRADE approach. Seven randomized controlled trials involving 4751 participants were included. Moderate-quality evidence indicated that Full CBT-I significantly improved absenteeism and presenteeism; whereas evidence for work productivity loss and activity impairment was of low quality. For Sleep Restriction Therapy (SRT), low-quality evidence supported its efficacy for presenteeism, work productivity loss, and activity impairment, whereas evidence for its effect on absenteeism was very low. SRT combined with sleep hygiene education may serve as an efficient first-step intervention for work productivity, whereas Full CBT-I offers broader efficacy.
