Abstract

Background

Non-suicidal self-injury (NSSI) is a growing public health concern, yet its prevalence among vocational high school students is underexplored. The relationships between autistic traits, sleep patterns, and life satisfaction in relation to NSSI remain poorly understood.

Methods

This cross-sectional study was conducted on 10,252 vocational high school students with an average age of 20.1 from June 2022 to June 2023. Utilizing the PROCESS 3.4.1 macro in SPSS, analyses were performed to investigate the potential mediation of sleep disturbances in the relationship between autistic traits and non-suicidal self-injury behavior. Furthermore, we investigated the moderating effect of life satisfaction on this relationship.

Results

8.2 % of vocational high school students in this study showed signs of NSSI issues. We found that sleep problems partially mediated the relationship between autistic traits and NSSI, accounting for 36.37 % of the mediation effect. Lastly, life satisfaction played a regulatory role in both direct and indirect paths of the aforementioned mediating model, with the mediation model remaining valid.

Conclusion

Among vocational high school students, the prevalence of NSSI is notable, with high autistic traits influencing the development of NSSI by impacting sleep. Furthermore, life satisfaction plays a modifying role in this pathway.
