Diabetes and depression


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.
