Integration of sleep and emotion treatment: a randomized trial of transdiagnostic CBT for comorbid insomnia
摘要
Insomnia frequently co-occurs with emotional disorders, yet integrated treatment approaches remain understudied. This study examined the efficacy of Transdiagnostic Cognitive Behavior Therapy (TCBT) for treating comorbid insomnia in patients with emotional disorders.
MethodsIn this double-blind randomized controlled trial, 32 university students with comorbid insomnia and emotional disorders were randomly assigned to either TCBT (n = 16) or waitlist control (n = 16). The TCBT group received 20 one-hour sessions of treatment. Insomnia severity was assessed using the Insomnia Severity Index (ISI) at baseline, post-treatment, and three-month follow-up.
ResultsMixed-model ANOVA revealed significant main effects for time (F = 52.18, p < .001, Eta-Squared = 0.635) and group (F = 45.55, p < .001, Eta-Squared = 0.603), and a significant time × group interaction (F = 61.66, p < .001, Eta-Squared = 0.673). The TCBT group showed large effect sizes for insomnia reduction from pre- to post-treatment (Hedges’ g = 3.75) and pre-treatment to follow-up (g = 3.07), with benefits maintained at three months. The waitlist group showed no significant changes.
ConclusionsTCBT demonstrated robust efficacy in treating comorbid insomnia among university students with emotional disorders, with effects maintained at follow-up. These findings suggest TCBT as a promising integrated treatment approach for this population.
