Cognitive-behavioural intervention for depression after stroke: Five single case studies on effects and feasibility

The purpose of the study was to investigate whether or not a cognitive-behavioural intervention for depression after stroke has an effect and is feasible. A single-subject quasi experimental design (SSED) was used with an AB design and follow-up. The participants were five first episode stroke patients attending outpatient rehabilitation in a rehabilitation centre in The Netherlands. Mood and quality of life were measured on four occasions over four weeks (baseline phase A). During the eight week intervention phase (B) a visual analogue measure of mood was administered three times a week. Immediately after the intervention, and one and three months later, the baseline measures were repeated. The intervention (phase B) was based on cognitive-behavioural principles: recognising negative thoughts and challenging them, learning principles of relaxation, and planning of pleasurable activities. Following intervention three patients reported they had improved, three patients reported a minor improvement in quality of life, and four patients reported a more positive mood. Three months later three patients reported fewer depressive symptoms. Both patients and therapist were positive about the intervention and three months later, in daily life, all patients still applied the strategies. It was concluded that despite some ambiguous results, it seems that the cognitive-behavioural intervention has an effect on patients' mood. The intervention was rated as feasible by both patients and therapists.
