Scientific title
Study objectives	The self-rating scores for depression will be more improved in the intervention arm than in the treatment as usual (control) arm.
Ethics approval(s)	Glasgow and Clyde Primary Care, Community and Mental Health Ethics Committee. Date of approval: 12/08/2008 (REC No: 08/S0701/65)
Health condition(s) or problem(s) studied	Diabetes and depression
Intervention	Trial status amended to 'stopped' as of 05/04/2013 due to notification of lack of staff/resources. Control arm: Treatment as usual Intervention arm: Treatment as usual plus computerised cognitive behavioural therapy (CCBT). The CCBT is a self-help intervention supported by mental health practitioners. Added as of 24/10/2008: The supported self-help intervention will comprise 4 support sessions over 6 weeks, and 6 sessions using an online CCBT package. It is approximated that this will take the participants 8 weeks to complete.
Intervention type	Other
Primary outcome measure(s)	Change in depression as measured by BDI-II, assessed at baseline, Month 4, 5 and 12.
Key secondary outcome measure(s)	1. Anxiety state and other depression measures will be carried out using the Hospital Anxiety and Depression Scale (HADS)and PHQ-9 at baseline, Month 4, 5 and 12 2. Social functioning will be measured using the Work and Social Adjustment Scale (WASAS) at baseline, Month 4, 5 and 12 3. Mental health literacy will be measured using a revised questionnaire from previous studies at baseline, Month 4, 5 and 12 4. Acceptability of the trial interventions will be measured using two satisfaction items asking overall satisfaction with the treatment option at Month 4 and 12 (this is in line with other similar studies) 5. Health care usage/costs will be costed using the Client Service Receipt Inventory (modified) and euroquol EQ-5D at baseline, Month 4, 5 and 12 6. Diabetes status: Hb1Ac will be sought using routine clinical data from clinical notes In addition, a qualitative interview will be carried out in a subset of participants from both arms at 5 months, to collect data for the following aspects of the self-help CCBT: 1. Personal experience of low mood 2. Interaction with support worker 3. First and subsequent experiences of CCBT 4. Outcome of CCBT
Completion date	31/07/2010
