Psychometric Analysis of the Short Version of the Self-Harm Screening Inventory for Gifted Adolescents

Deliberate Self-Harm (DSH) is the intentional destruction of healthy body tissue without the intent to commit suicide. Given the rapidly increasing prevalence of non-suicidal self-injury (NSSI) among adolescents, it is essential to conduct a systematic analysis of the risk and protective factors associated with these behaviors using tools that demonstrate validity and reliability. Therefore, the current study was conducted to analyze the psychometric properties of the abbreviated version of the Self-Harm Screening Inventory for adolescents.

In this survey study, 300 gifted adolescents were selected using the convenience sampling method. They completed the short version of the Self-Harm Screening Inventory for Adolescents (Kim et al., 2022), the Depression, Anxiety and Stress Scale (Lovibond & Lovibond, 1995), and the Satisfaction with Life Scale (Diener, Emmons, Larsen, & Griffin, 1985).

A confirmatory factor analysis supported the hypothesized one-factor structure. The one-factor model had a good fit. The SHSI also demonstrated good internal consistency (Cronbach's alpha = 0.89). Additionally, the Subjective Happiness Scale Inventory (SHSI) was positively correlated with the Depression, Anxiety, and Stress Scale, and negatively correlated with the Satisfaction with Life Scale. These correlations support the criterion validity of the abbreviated version of the Self-Harm Screening Inventory for adolescents.

The findings suggest that the SHSI is a reliable and valid tool for screening self-harm behaviors among adolescents.
