Abstract
OBJECTIVE: To evaluate the effect of a dialogue-based intervention targeting psychosocial well-being at 12 months post-stroke. DESIGN: Multicenter, prospective, randomized, assessor-blinded, controlled trial with two parallel groups. SETTING: Community. SUBJECTS: = 156). INTERVENTIONS: The intervention group received a dialogue-based intervention to promote psychosocial well-being, comprising eight individual 1-1½ hour sessions delivered during the first six months post-stroke. MAIN MEASURES: The primary outcome measure was the General Health Questionnaire-28 (GHQ-28). Secondary outcome measures included the Stroke and Aphasia Quality of Life Scale-39g, the Sense of Coherence scale, and the Yale Brown single-item questionnaire. RESULTS: The mean (SD) age of the participants was 66.8 (12.1) years in the intervention group and 65.7 (13.3) years in the control group. At 12 months post-stroke, the mean (SE) GHQ-28 score was 20.6 (0.84) in the intervention group and 19.9 (0.85) in the control group. There were no between-group differences in psychosocial well-being at 12 months post-stroke (mean difference: -0.74, 95% confidence interval (CI): -3.08, 1.60). The secondary outcomes showed no statistically significant between-group difference in health-related quality of life, sense of coherence, or depression at 12 months. CONCLUSION: The results of this trial did not demonstrate lower levels of emotional distress and anxiety or higher levels of health-related quality of life in the intervention group (dialogue-based intervention) as compared to the control group (usual care) at 12 months post-stroke.
