title: Moderators of Treatment Effects of a Video-Based Cognitive-Behavioral Therapy for Insomnia Comorbid With Cancer.
abstract: To assess the moderating role of demographic and clinical variables on the efficacy of a video-based cognitive behavioral therapy for insomnia (VCBT-I) among breast cancer patients.
  
  
  
  As part of a randomized controlled trial, 80 women received VCBT-I.
  
  
  
  Patients with a more advanced breast cancer were less likely to show reductions on the Insomnia Severity Index (ISI) and increased sleep efficiency at posttreatment. Patients using an antidepressant medication showed a larger reduction of ISI scores and a higher rate of insomnia remission. Remission of insomnia was also significantly more likely in individuals with a higher annual income. When using a multivariate binary classification tree analysis, the best and unique predictor of insomnia remission was having a less severe baseline ISI score.
  
  
  
  Although efficacious in general, VCBT-I does not appear to be an optimal format for everybody.
