Measurement of Perceived Functions of Non-Suicidal Self-Injury for Chinese Adolescents

Abstract

Due to the lack of validated assessment tools for motives of non-suicidal self-injury behaviors in the Chinese contexts, this study aims to evaluate the psychometric properties of the Chinese version of the Functional Assessment of Self-Mutilation (C-FASM). A total of 345 secondary school students (mean age = 11.41 years), who reported non-suicidal self-injury in the past year, voluntarily participated in the questionnaire survey. Confirmatory factor analysis results supported a second-order model of 4 motivational factors. The overall scale scores had significant correlations with depression, anxiety, impulsiveness, self-esteem, social support, and suicidal ideation. The internal consistency of the scale was also satisfactory. The C-FASM is a valid and reliable instrument for assessing non-suicidal self-injury among nonclinical Chinese adolescents.
