Abstract

Internet-delivered cognitive behavioural therapy (CBT) can be an effective method for treating major depression, but it often works best when therapist support is provided in the form of e-mail support or telephone calls. The authors investigated whether there were any intraclass correlations within therapists when delivering CBT for major depression via the Internet. They included data from two trials involving 10 therapists treating a total of 103 patients. The results of a nested one-way model in which participants were treated as raters for different therapists indicated that measures pertaining to symptom reductions (Beck Depression Inventory, Montgomery-Asberg Depression Rating Scale-Self Report, and Beck Anxiety Inventory) did not support a clustering of data within therapists. However, the outcome on a secondary measure of life satisfaction (Quality of Life Inventory) yielded a significant intraclass correlation coefficient for therapists (r = .24, p = .001). The authors propose that text-based treatments are less sensitive to therapist effects when it comes to the primary symptom measures, but that treatment effects not directly targeted by the specific treatment program may be more dependent on the way the support is given and by whom (therapist effect). Limitations of the study are discussed.

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.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-10.

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.
