Internet-Based CBT for Depression with and without Telephone Tracking in a National Helpline: Randomised Controlled Trial
Open accessAbstract
BACKGROUND: Telephone helplines are frequently and repeatedly used by individuals with chronic mental health problems and web interventions may be an effective tool for reducing depression in this population. AIM: To evaluate the effectiveness of a 6 week, web-based cognitive behaviour therapy (CBT) intervention with and without proactive weekly telephone tracking in the reduction of depression in callers to a helpline service. METHOD: 155 callers to a national helpline service with moderate to high psychological distress were recruited and randomised to receive either Internet CBT plus weekly telephone follow-up; Internet CBT only; weekly telephone follow-up only; or treatment as usual. RESULTS: Depression was lower in participants in the web intervention conditions both with and without telephone tracking compared to the treatment as usual condition both at post intervention and at 6 month follow-up. Telephone tracking provided by a lay telephone counsellor did not confer any additional advantage in terms of symptom reduction or adherence. CONCLUSIONS: A web-based CBT program is effective both with and without telephone tracking for reducing depression in callers to a national helpline.

TL;DR
In a national helpline RCT, a 6-week web CBT program (BluePages + MoodGYM) reduced depression more than treatment as usual at post-intervention and 6-month follow-up, with large effect sizes. Adding weekly telephone tracking by a lay counsellor did not improve symptom reduction or adherence, and tracking alone was not effective.
Key findings
- Among 155 callers randomised, web CBT conditions showed greater decline in CES-D depression than control at post-intervention and 6 months. Effect sizes were large: web only vs control g = 0.76 post-intervention and 1.19 at 6 months; web with tracking vs control g = 1.04 post-intervention and 1.26 at 6 months.
- Tracking alone did not differ significantly from control at post-intervention or 6 months, and telephone tracking did not confer additional benefit over web CBT alone for symptom reduction or adherence.
- At 6-month follow-up, clinical caseness on the CES-D was 43.5% in web only, 50.0% in web with tracking, and 90.9% in control. NNT was 6.03 for web only and 4.43 for web with tracking.
- Adherence did not differ significantly between web conditions: average MoodGYM modules completed were 1.5 (SD = 1.89) for web only and 2.0 (SD = 1.88) for web with tracking; 15.8% and 17.8%, respectively, completed all five modules.
Methods
- Randomised controlled trial recruiting callers to Lifeline’s 24-hour telephone counselling service in four major Australian cities; eligibility included age ≥18, English, Internet access, and K10 score ≥22.
- Participants were randomised to web only, web with tracking, tracking only, or treatment as usual; the web intervention combined BluePages psychoeducation in Week 1 with five MoodGYM CBT modules over Weeks 2–6, and tracking consisted of weekly 10-minute calls from a telephone counsellor.
- Primary outcome was CES-D depression, analysed on an intention-to-treat basis using mixed models repeated measures ANOVA with planned contrasts; effect sizes used Hedges’ g, and logistic/linear regressions examined dropout and caseness.
Limitations
- Stated: intervention completion rates were lower than in some other web-based depression trials; symptom severity remained high post-intervention; greater dropout in the web with tracking condition may have inflated effects in that condition; two outliers were excluded from primary analyses; and depression caseness was estimated by CES-D cutoff rather than diagnostic interview.
- Stated: the trial was a true effectiveness trial using a volunteer workforce, which may contribute to recruitment and adherence issues relative to efficacy studies.
- Evident from the text: the achieved sample of 155 was below the original target of 400, although the authors state it maintained above 80% power to detect differences of less than 0.5 SD units in planned comparisons between individual treatment arms.

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.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
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.
