Study information
Scientific title
Effects of a psychoeducational course on treatment outcomes in mildly to moderately depressed diabetic patients
Acronym
EPOT
Study hypothesis
Screening depressive symptoms in diabetic patients attending their regular medical check-ups, and including those with severe depressive symptoms in a psychoeducational intervention accompanied by a structured follow-up will improve their awareness of the interaction between depression and diabetes, and provide them with necessary support to make an informed decision about self-help and depression treatment. It is also hypothesised that improving patients' activation and their personal competence will positively affect the course of depressive symptoms, diabetes-associated emotional problems, glycaemic control and perceived quality of life.
Ethics approval
The study was approved by the Ethics Committee, Vuk Vrhovac Institute in 2006 (ref: No.03-188)

Condition
Diabetes mellitus, depression
Intervention
The intervention comprises 3 interactive small group meetings (8-10 members), each lasting for 90 minutes. The included topics will be:
1. Symptoms of depression; interaction of depression and diabetes
2. Alleviating burden of depression through activities and problem solving
3. Associations between depression and cognitive processes - thoughts, beliefs and attitudes that induce and maintain depression
The first two meetings are held within one week of each other, and the third one after one month. Patients will be provided with a self-help manual for overcoming depressive disturbances, based on the "Coping with depression" course by P.M. Lewinshon (see below for reference). For this study purpose, the programme has been partially modified and adjusted to specific emotional problems related to diabetes. Besides general information (prevalence and cause of depression, interaction with diabetes, treatment modalities, prevention of relapse), exercises to recognise and modify cognitive patterns that contribute to depression maintenance are included.
A run-in period aimed at assessing patients' knowledge and diabetes self-care-related skills will precede the intervention.
The patients in the control group will be given feedback about the severity of their depressive symptoms and receive counselling about appropriate forms of treatment.
