• We report expectations, satisfaction, and subjective symptomatic and psychosocial changes in obsessive compulsive disorder patients undergoing deep brain stimulation therapy. • Patients experienced high satisfaction, and greatest improvement in quality of life, rumination, mood, and cognitive flexibility. • The study informs psychosocial mechanisms of DBS and ethical debates, and encourages patient centred approaches to DBS care. Severe and refractory psychiatric patients can experience complex and profound changes in symptomology, functioning and well-being from deep brain stimulation (DBS) therapy. Currently, the efficacy of DBS is assessed by clinician rated scales of primary symptoms, yet this does not capture the multitude of DBS mediated changes or represent the patient perspective. We aimed to elucidate the patient perspective in psychiatric DBS application by investigating 1) symptomatic, and 2) psychosocial changes, 3) therapeutic expectations and satisfaction, 4) decision-making capacity, and 5) clinical care recommendations from treatment refractory obsessive–compulsive disorder (OCD) DBS patients. Participants enrolled in an open label clinical trial of DBS therapy for OCD who had reached clinical response were invited to participate in a follow up survey. Participants completed a 1) feedback survey relating to goals, expectations, and satisfaction of therapy, and 2) self-report questionnaires on psychosocial functioning including quality of life, cognitive insight, locus of control, rumination, cognitive flexibility, impulsivity, affect, and well-being. Greatest change was reported for quality of life, rumination, affect and cognitive flexibility. Participants reported realistic expectations, high satisfaction, adequate pre-operative education and decision-making capacity; and advocated for greater access to DBS care and more widespread support services. This is the first identified investigation on psychiatric patient perspectives of functioning and therapeutic outcomes following DBS. Insights from the study have implications for informing psychoeducation, clinical practices, and neuroethical debates. We encourage a greater patient-centred and biopsychosocial approach in evaluating and managing OCD DBS patients, by considering personally meaningful goals and addressing symptomatic and psychosocial recovery.
