This study aimed to examine the effect of a psychoeducation-based motivational interviewing intervention on schizophrenia-related knowledge and hope levels among patients diagnosed with schizophrenia. The study employed a randomized controlled experimental design with pre-test, post-test, and one-month follow-up measurements. Participants were recruited from a community mental health center and assigned to an intervention group or a control group. The intervention group participated in a structured psychoeducation-based motivational interviewing program consisting of one preparatory session followed by five main sessions, while the control group continued to receive routine community mental health services. Knowledge about schizophrenia and hope levels were assessed using validated measurement tools.
