Appropriate intervention to prevent the transition from SD to PSD is thus imperative. As a form of short-term psychotherapy adapted for individuals with cognitive and communication impairments, behavioral activation therapy (BAT) may be a suitable choice. However, the effects of BAT on psychological outcomes in stroke patients with SD has not been established. This study investigated the feasibility and effectiveness of BAT in reducing the development of depressive symptoms in this patient population.Methods: A double-blind, randomized controlled trial was performed. Seventy participants were randomized to either a BAT group (n=35) or a control group (n=35). Participants in the BAT group received a six-week BAT intervention. The feasibility of BAT was assessed by the number of sessions attended by participants, and the acceptability of BAT to participants and the incidence of adverse events were recorded. The primary clinical outcome measure was the Center for Epidemiological Studies Depression Scale (CES-D) and the 17-item Hamilton Depression Scale (HAMD-17) at baseline, six weeks, and three months after the group allocation. Secondary outcomes included behavioral activation and the incidence of depression.Results: The intervention was feasible and acceptable, with 94.3% of participants in the BAT group (33 of 35) attending at least five sessions. No adverse events were reported in either group. Compared with the control group, the BAT group showed significant improvements in the CES-D (F=67.689, P< 0.05), HAMD-17 (F=4.170, P< 0.05), and behavioral activation (F=25.355, P< 0.05) scores after intervention, and these differences were maintained at the three-month assessment.Conclusion: BAT appears to be feasible and efficacious for reducing depressive symptoms and increasing behavioral activation among stroke patients with SD. The findings of this study may contribute to the primary prevention of PSD.Keywords: stroke, subthreshold depression, post-stroke depression, behavioral activation therapy
