The sample of the study consisted of patients diagnosed with schizophrenia and other psychotic disorders who met the sampling criteria determined in the study (n=52). In the Power analysis of the research, the sample size was determined as 2 groups, with 26 people as the experimental group and 26 people as the control group, with a total of 52 people in the 95% confidence interval. In the study, 52 patients diagnosed with schizophrenia and other psychotic disorders who met the sample selection criteria and volunteered to participate in the study were divided into experimental and control groups using simple random sampling technique. As data collection tools in the research; Personal Information Form, Healthy Life Style Behavior Scale II, Health Improvement Profile, Anthropometric Measurements and Vital Findings and Stage of Change Diagnosis Form were used. The implementation of the research was completed in four stages. In the first stage, the "Health Promotion Model and Motivational Interview-Based Health Protection and Promotion Program" was developed by the researcher in line with the literature review. In the second stage, after the program was introduced to all participants who met the inclusion criteria and their written consent was obtained, pre-tests including the variables of the research were applied, and then the participants were assigned to the experimental and control groups by randomization method. Sessions were held in the form of individual interviews due to the pandemic and social distance conditions. In the third stage, the Health Promotion Model and the Motivational Interview-Based Health Protection and Promotion Program were applied to the experimental group, which consisted of 6 sessions and lasted an average of 60-120 minutes to discuss the warm-up period and the main themes of the sessions in each individual session.

"Weekly Nutrition Follow-up Form", "Weekly Step Count Follow-up Form", "Weekly Stress Follow-up Form", "Weekly Leisure Activities Follow-Up Form" and "Weekly Sleep Diary" prepared by the researcher for the experimental group participants were handed over to the patients as homework. They were asked to fill it out weekly and bring it to their next session. No intervention was made to the patients in the control group during the six-week period.
