Summary

Non-suicidal self-injury (NSSI) is a growing global mental health challenge, distinct from suicidal behavior, with unique risk factors and mechanisms. Existing risk assessment tools do not focus on differentiating NSSI from suicidal self-harm or comprehensively evaluate risk and protective factors specific to NSSI. There is a lack of clinically applicable, validated scales dedicated to assessing NSSI risk, particularly in psychiatric populations. The present study is made to design the Psychiatric Non-Suicidal Self-Injury Risk Assessment Scale, a 39-item scale that evaluates static/dynamic risk factors and protective factors for NSSI in psychiatric patients.

Detailed description

The initial item pool was created through literature review, semi-structured interviews, and group discussions. Two rounds of the Delphi were employed with twenty experts. We analyzed items using critical ratio, correlation coefficient, factor analysis, and Cronbach's α coefficient. Exploratory factor analysis determined item weights, while reliability analyses evaluated internal consistency, test-retest, inter-observer and split-half methods. In the validity analyses, CVI, construct validity and criterion validity were used. ROC curve established the optimal diagnostic threshold and the risk stratification was performed.
