Abstract

Research on the psychological resources needed to inhibit non-suicidal self-injury (NSSI) remains relatively scarce. This study aimed to translate and validate a Korean version of a scale measuring self-efficacy, a key factor in resisting NSSI across various scenarios. Data were collected from 283 university students. Analyses—factor analysis, correlation analysis, group comparisons, logistic regression, and latent profile analysis —were performed on the Self-Efficacy to Resist NSSI Scale (SER-NSSI). The scale's three-factor structure—risk context, protective context, and reminders context—proved suitable. It displayed significant correlations with related factors and effectively distinguished or predicted individuals with NSSI experiences, aiding in the identification of potential at-risk groups based on subfactors. These findings affirm the scale's reliability and validity. This research offers vital insights for NSSI prevention and recovery and aids in developing clinical intervention strategies.
