Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Observation Group

Scales are used to get primary indicator and secondary indicators. The sample size should be set at 5 to 10 times the number of items, with a minimum total sample of 200. Additionally, an extra sample should be calculated to account for a potential 10-20% attrition rate, mitigating the impact of possible data loss. Given that the initial version scale consisted of 55 items, the minimum required sample size is 330.
