This experimental study was carried out using a pre-test/post-test control group model to evaluate the effect of a “Brief Cognitive Behavioural Stress Management Programme” (BCBSMP) on mental status, coping with stress attitude, and caregiver burden while caring for patients with schizophrenia. A total of 61 caregivers who provided care for schizophrenia patients at a community mental health centre were included in the study. Caregivers were matched according to gender and scale scores and were assigned to either the study or the control group. Before and after the programme, caregivers in both groups were given the “Demografic Data Form”, “Zarit Caregiver Burden Scale”, “Coping Attitude Evaluation Scale”, “Stress Indicators Scale”, and the “General Health Survey-28”. Caregivers in the study group were taken to a BCSMP one session per week (each session lasted 120 min) for seven weeks. We determined that the stress indicators, the risk of developing a psychological disorder, and caregiver burden decreased and skills related to both the problem-oriented and emotion-oriented aspects of stress increased in the study group after the programme.
