Abstract

BACKGROUND:

In a recent 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.

METHODS:

Depressed 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.

RESULTS:

Uptake 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.

LIMITATIONS:

Associations 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.

CONCLUSIONS:

Although CCBT might be a feasible and acceptable treatment for depression, means to improve treatment adherence are needed for moderately to severely depressed individuals.
