title: Determinants of success for computerized cognitive behavior therapy: examination of an insomnia program.
abstract: This study evaluated plausible moderators of outcome in a 6-week computerized treatment for insomnia. Using secondary data from two randomized controlled trials, participants were 228 adults with chronic insomnia. Participants received computerized treatment from their homes. Outcomes were assessed using a sleep diary, as well as several standardized self-report scales. Using linear mixed models with SPSS, treatment was largely robust to comorbid conditions, education, age, and gender. Results showed that psychiatric comorbidity and education moderated the impact of treatment on fatigue and that sleep symptom comorbidity moderated the impact of treatment on maladaptive attitudes about sleep. Implications of these findings are that more widespread use of computerized treatment for insomnia may be warranted.
