Abstract :Purpose: This study was conducted to adapt the Self-Harm Screening Inventory, the most up-to-date self-report instrument, into Turkish and to examine its psychometric properties in a Turkish sample. Materials and Methods: This study included 571 adolescents and examined the psychometric properties of the Self-Harm Screening Inventory-Turkish Form (SHSI-TR) scale via classical test theory (CTT) and item response theory (IRT). During the analysis process, a graded response model (GRM) was applied to analyze the factor structure and item properties of the SHSI-TR items. Additionally, the criterion validity of the scale was assessed by examining its relationship with the Symptom Control List-90-Revised (SCL-90-R) and the Suicide Rumination Scale (SRS). Results: The Cronbach\\\'s alpha internal consistency coefficient of the SHSI-TR was .72. The Guttman two-half reliability coefficient was .73. The SHSI-TR was also positively correlated with the SCL-90-R subscales of somatization (r = .12, p < .05), interpersonal sensitivity (r = .17, p < .01), depression (r = .26, p < .01), anxiety (r = .22, p < .01), and psychoticism (r = .22, p < .01). Conclusion: In conclusion, the GRM results demonstrated that the items of the SHSI-TR possess strong measurement properties. The scale represents a unidimensional structure in terms of content validity and statistical consistency. The obtained factor loadings and item parameters support the validity and reliability of the SHSI-TR as a measurement tool capable of distinguishing individuals\\\' levels of self-harm.
