Abstract
This is the protocol for a Campbell review. The primary aim is to estimate the relative efficacy of different modes of CBT delivery compared with control conditions for reducing depressive symptoms in adolescents. The secondary aim is to compare the different modes of delivery with regards to intervention completion/attrition (used as a proxy for intervention acceptability). The review will provide relative effect estimates and ranking probabilities for each outcome based on intervention delivery.
Highlights
A review of computerised cognitive behavioural therapy (CBT) for anxiety and depression found that included studies varied considerably in terms of therapist support (Richardson, Stallard, & Velleman, 2010). This is potentially important because there is some evidence based on an analysis of computerised psychotherapies with adults that the effect on depressive symptoms is moderated by the level of therapist support, with larger effects associated with therapist involvement (Andersson & Cuijpers, 2009)

Unguided self‐help: This involves educating the client in the principles of CBT through reading material and helping them apply it through quizzes and activities
Summary
Depression is a public health problem and common among adolescents. It is estimated that around one in ten adolescents in the USA experience at least one major depressive episode per year (Center for Behavioral Health Statistics and Quality, 2015). A review of computerised CBT for anxiety and depression found that included studies varied considerably in terms of therapist support (Richardson, Stallard, & Velleman, 2010) This is potentially important because there is some evidence based on an analysis of computerised psychotherapies with adults that the effect on depressive symptoms is moderated by the level of therapist support, with larger effects associated with therapist involvement (Andersson & Cuijpers, 2009). As delivery modalities will differ in terms of demands on resources, this review may have important cost‐benefit implications, which could be examined in further research (Arnberg, Linton, Hultcrantz, Heintz, & Jonsson, 2014)
