Internet-based self-help for depression: randomised controlled trial
Open accessAbstract
Background: Major depression can be treated by means of cognitive–behavioural therapy but as skilled therapists are in short supply there is a need for self-help approaches. Many individuals with depression use the internet for discussion of symptoms and to share their experience. Aims: To investigate the effects of an internet-administered self-help programme including participation in a monitored, web-based discussion group, compared with participation in web-based discussion group only. Method: A randomised controlled trial was conducted to compare the effects of internet-based cognitive–behavioural therapy with minimal therapist contact (plus participation in a discussion group) with the effects of participation in a discussion group only. Results: Internet-based therapy with minimal therapist contact, combined with activity in a discussion group, resulted in greater reductions of depressive symptoms compared with activity in a discussion group only (waiting-list control group). At 6 months' follow-up, improvement was maintained to a large extent. Conclusions: Internet-delivered cognitive–behavioural therapy should be pursued further as a complement or treatment alternative for mild-to-moderate depression.

Studies of clinical predictors of adherence have typically reported that baseline depression symptom severity is unrelated to adherence in online interventions.
“Studies of clinical predictors of adherence have typically reported that baseline depression symptom severity is unrelated to adherence in online interventions (Andersson et al., 2005;Kenardy, McCafferty, & Rosa, 2003;Warmerdam et al., 2008).”

Other studies included discussion groups as part of an online intervention but failed to include the groups as a unique research variable, so could not identify the impact of the group on intervention effectiveness.
“A number of other studies [28–30] have also included discussion groups delivered in the form of bulletin boards as part of an online intervention but have failed to include the groups as a unique research variable so have been unable to identify the impact of the group on the effectiveness of the intervention.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
