Plain English Summary

Background and study aims
Many people with depression would like to receive a 'talking treatment' (counselling or psychotherapy). The form of talking treatment that is supported by the greatest amount of evidence is Cognitive Behaviour Therapy (CBT). At the present time, there are too few therapists to treat people with depression. Recently, a form of CBT has been developed that can be delivered by computer. Computerised CBT can be delivered in the patient’s own time (and potentially in their own home) and does not require waiting for a therapist. Several computer packages of CBT have been developed. Some of these are free to use and are available over the internet, whilst some are commercial products and have to be purchased at substantial cost to the NHS. We need more information about the effectiveness of these packages and we need to know whether the additional cost of purchasing commercially available products is a sensible use of limited NHS funds. As part of a study comparing two CBT packages with usual GP care, we wish to assess the clinical and cost effectiveness of the addition of regular telephone support to computerised CBT.

Who can participate?
Patients with depression, aged 18 and over

What does the study involve?
All participants receive usual GP care and computerised CBT (MoodGYM - a free-to use web-based CBT programme for depression). In addition participants are randomly allocated to receive either weekly telephone support calls or no telephone support calls. We examine whether this is effective at reducing the symptoms of depression over a 12-month follow-up period.

What are the possible benefits and risks of participating?

Drug names

Primary outcome measure

Depression severity and symptomatology (PHQ-9 >=10), measured by a validated self-report measure (the Patient Health Questionnaire [PHQ-9]) depression score at four months.

Secondary outcome measures

Outcome measures as of 01/04/2016:
1. Self-reported depression severity, measured by the 9-item Patient Health Questionnaire (PHQ-9) at four and 12 months as a continuous measure
2. Anxiety, measured using the Generalised Anxiety Disorder Assessment (GAD-7) at 4 and 12 months
3. Somatoform complaints, measured using the Patient Health Questionnaire 15 (PHQ-15) at 4 and 12 months
4. Health state utility, measured using EuroQol (EQ5D) at 4 and 12 months

Original secondary outcome measures:
1. PHQ-9 measured at 12 months
And the following outcome measures at both 4 and 12 months:
2. Anxiety, measured using the Generalised Anxiety Disorder Assessment (GAD-7)
3. Somatoform complaints, measured using the Patient Health Questionnaire 15 (PHQ-15)
4. Health-related quality of life, measured using the Short-Form 12 (SF-12)
5. Health state utility, measured using EuroQol (EQ5D) at 4, 12 and 24 months

Editorial Notes

06/03/2017: Publication reference added. 07/12/2016: Publication reference added. 24/05/2016: The publication and dissemination plan and availability of the participant level data has been added. 12/05/2016: Plain English summary added. 01/04/2016: Ethics approval information added and the secondary outcome measures have been updated. The overall trial end date has been updated from 30/12/2012 to 31/05/2015 and the recruitment end date has been updated from 30/12/2012 to 05/04/2014. In addition, the target number of participants has been updated from 200 to 350, to allow detection of a smaller difference of 0.30 with 80% power at a level of significance of 0.05 (one-sided) accounting for loss to follow up of 20% (received REC approval in 2012).
