Single Case Experimental Design Examining Cognitive Behavioural Therapy for Post-Stroke Depression

Abstract

Background. Post-stroke depression (PSD) is common in older-age adults and is typically treated with cognitive-behavioural therapy (CBT). However, research has ascertained mixed findings regarding the efficacy of CBT for PSD in older-age adults, with limited evidence in people from global majority backgrounds. Materials and Methods. This case study used single case experimental design methodology to examine the effectiveness of CBT for PSD in a black, older-age man. The effects of health conditions, cohort beliefs, transitions in role investments, socio-cultural context and early experiences on the client’s thoughts, emotions, physical sensations and behaviours were formulated, before behavioural activation was used to increase engagement in meaningful and pleasurable activities. Results. Throughout therapy, the client’s mood, motivation and optimism for the future improved, and their depression and anxiety symptoms reduced. Conclusions. This case study offers tentative evidence that CBT for PSD may be effective in black older-age adults.
