Use and acceptability of unsupported online computerized cognitive behavioral therapy for depression and associations with clinical outcome

Background ecent randomized trial, we were unable to confirm the previously reported high effectiveness of CCBT. Therefore, the aim of the current study was to have a closer look at usage and acceptability (i.e. expectancy, credibility, and satisfaction) of the intervention. s sed participants (N = 200) were given login codes for unsupported online CCBT. A track-and-trace system tracked which components were used. We used a 9-month follow-up period. s was sufficient, but dropout was high. Many usage indices were positively associated with short-term depressive improvement, whereas only homework was related to long-term improvement. Acceptability was good and expectancy could predict long-term, but not short-term outcome. tions ations between use of CCBT and improvement are merely correlational. Our sample was too depressed in relation to the scope of the intervention. We relied on online self-report measures. Analyses were exploratory in nature. sions gh CCBT might be a feasible and acceptable treatment for depression, means to improve treatment adherence are needed for moderately to severely depressed individuals.
