Effectiveness and Acceptability of Internet-delivered Treatment for Depression, Anxiety and Stress

Summary

The aims of this study are to test the effectiveness and acceptability of internet-delivered treatment for depression, anxiety and stress in university students. These data will inform the methods for a future randomized controlled trial.

The trial will establish an initial estimate of the effectiveness of these online interventions for students in terms of within-group effect sizes associated with changes in depression, anxiety and stress from pre to post-intervention and follow-up. These data will be used to estimate the sample size for a future trial to ensure that the study is sufficiently powered. A conservative estimate using the 90% upper confidence limit will be used to inform the sample size calculation of the definitive RCT.

Acceptability of the intervention to participants will be assessed using data on usage and engagement with the intervention (e.g. percentage of participants completing each module, average number of log ins, average time spent per session and total time spent on the program). These data are acquired through the online SilverCloud system. Satisfaction with will be assessed through the use of a post-intervention questionnaire on satisfaction with accessing and using an online delivery format for treatment.
