To explore the relationship between the romantic status of vocational school students in Guizhou Province and their engagement in non-suicidal self-injury (NSSI), as well as the mediating role of difficulties in emotion regulation, providing a reference for the prevention of adolescent NSSI behaviors.
A questionnaire survey was conducted from October to December 2023, utilizing a multi-stage stratified cluster random sampling method to select students from nine vocational schools in Guizhou Province. The Chinese version of the Adolescent Non-Suicidal Self-Injury Assessment Questionnaire (ANSAQ) and the Difficulties in Emotion Regulation Scale (DERS) were used to measure NSSI behaviors and emotion regulation difficulties among vocational students. The mediating effect of difficulties in emotion regulation was examined using categorical variable mediation methods.
The prevalence of NSSI among vocational students in Guizhou Province was 27.4%. The standardized relative direct effect of experiencing a breakup on NSSI was 0.575 (95%CI: 0.104 to 0.258), and the relative mediating effect was 0.421 (95%CI: 0.062 to 0.203), with the mediating effect accounting for 26.8% of the total effect. Difficulties in emotion regulation fully mediated the relationship between being in a romantic relationship and NSSI, with the mediating effect constituting 47.3% of the total effect. For students who had previously been in a relationship but were now in the post-breakup phase, the standardized relative direct effect on NSSI was 0.008 (95%CI: -0.021 to 0.037), and the standardized relative mediating effect was 0.011 (95%CI: -0.001 to 0.024), both of which were not significant.
Differences in emotion regulation abilities across various romantic statuses partially explain the occurrence of individual NSSI behaviors. Enhancing adolescents’ emotion regulation skills can help them establish healthy emotional perspectives and positive interpersonal relationships, thereby effectively reducing the incidence of NSSI behaviors and positively impacting adolescent mental health within the public health domain while fostering harmonious social relationships.
