Abstract
Objective: To develop and test the psychometric properties of the Schizophrenia Relapse Risk Assessment (SRRA) tool. Materials and Methods: The study was conducted in two phases: 1) item generation to examine content validity and linguistic comprehension, and 2) investigation of reliability and concurrent validity with the Positive and Negative Syndrome Scale (PANSS). The sample consisted of 184 schizophrenia patients from two psychiatric hospitals. Psychometric properties were analyzed using the content validity index, internal consistency reliability (Kuder-Richardson Formula 21, KR-21), construct validity through factor analysis, and concurrent validity using Pearson's correlation coefficient. Results: The SRRA comprised three components: illness denial and noncompliance (3 items), psychotic features and behavior dysregulation (5 items), and irrational fear (2 items), totaling 10 items. The tool explained 46.30% of the overall variance. It demonstrated excellent content validity (Item-content validity index: I-CVI=1), good reliability (KR-21=0.75), and a moderately high positive correlation with PANSS (r=0.75, p=0.04). Conclusion: The SRRA exhibits high psychometric properties in terms of validity and reliability, making it suitable for assessing relapse risk in schizophrenia patients.
