The study examined 110 individuals aged 18-65 who were diagnosed with schizophrenia and applied to the S.U. Faculty of Medicine Mental Health and Diseases Polyclinic in the last year, according to the inclusion-exclusion criteria. A total of 50 individuals diagnosed schizophrenia were included in the study. These individuals were randomly assigned to two groups: intervention and control. Pre-test data were collected using the "Personal Information Form", "Modified Engulfment Scale", "SF 36 Quality of Life Scale" and "Illness Management and Recovery Scale-Patient Form" from the intervention and control groups by researchers between August 2024 and February 2025 in the Group Therapy Room of the Mental Health and Diseases Polyclinic, based on self-reporting. The "Illness Management Skills Training" was applied to the intervention group in 4 groups, one session per week, for a total of 12 weeks. At the end of the Illness Management Skills Training, both the intervention and control groups were administered the "Modified Engulfment Scale", "SF 36 Quality of Life Scale" and "Illness Management and Recovery Scale-Patient Form". No intervention was applied to the control group throughout the 12-week program; the patients continued with their routine outpatient clinic check-ups.
