Study hypothesis

1. Patients using the CBT self-help materials will have:
1.1. Improved mood measured on the Beck Depression Inventory (BDI-II)
1.2. Improved social functioning measured on the Clinical Outcome Measure in Routine evaluation - Outcome Measure (CORE-OM)
1.3. Lower health care costs
1.4. Improved knowledge of the causes and treatment of depression compared to the control group receiving treatment as usual
2. Written self-help will be acceptable to both patients and staff within a primary care setting

Depressive symptoms


We are evaluating a structured self-help workbook treatment for mild to moderate depression called Overcoming Depression: A Five Areas Approach. A randomised controlled study design comparing treatment as usual as a control (arm 1); and supported self-help via three 40-minute appointments at week 1, 2 and one month (the '2 + 1' model, Barkham et al, 1996) comprising the second arm of the study.

Intervention type



Not Specified

Drug names

Primary outcome measures

Comparison between the Beck Depression Inventory -II scores for the two randomised groups (self help plus treatment as usual versus TAU) using a 2 sample 2-sided t-test at 4 months.

Secondary outcome measures

Psychological symptoms, well-being, risk and social functioning (using the CORE-OM scale), and acceptability of the intervention (using the Client Satisfaction Questionnaire- CSQ) compared to treatment as usual. In addition, the health care costs of both arms are being evaluated and the Euroquol (European Quality of Life measure) used to record health status and health-related quality of life change. Secondary analyses will also examine the impact of treatment patient knowledge. Further analyses that adjust the treatment effect for a pre-specified set of baseline covariates thought to be of influence on the treatment effect such as use of antidepressants, other self-help materials, and the chronicity of depression using Normal Linear models, will be considered. The approach by Jacobson et al, (1991) to present change in the group under study at the level of the individual will also be used. Categorical data will be compared between the two groups using chi-squared tests and logistic regression to adjust for covariates.
