Summary
A striking 34.6% of adolescents reported engaging in non-suicidal self-injury (NSSI), highlighting a critical mental health concern. School bullying significantly increased the risk of NSSI, with those bullied being over twice as likely to self-harm. Mindfulness emerged as a protective factor, reducing NSSI risk by 2% for each unit increase in mindfulness score. Notably, mindfulness practices accounted for 34% of the relationship between bullying and NSSI, suggesting that fostering mindfulness could effectively combat the negative impacts of school bullying on youth mental health.
Abstract
Non-suicidal self-injury (NSSI) poses a significant challenge to the health and well-being of children and adolescents, with prior studies suggesting a strong association with experiences of school bullying. While mindfulness has been identified as a protective factor against NSSI, its mediating role in the relationship between school bullying and NSSI remains insufficiently investigated. Using a representative sample from Yunnan Province, China, this study aims to contribute to the understanding of the relationship between school bullying, NSSI, and mindfulness. A population-based sample of 5897 adolescents in two places of Yunnan Province were surveyed by using self-administered questionnaires. Logistic regression model was used to measure the association between school bullying and NSSI. Path model was further fitted to examine the mediation of mindfulness in the association between school bullying and NSSI. The lifetime NSSI prevalence in our study sample was 34.6% (95% CI: 30.3%-39.0%). School bullying was associated with an increased risk of NSSI (OR = 2.02, 95% CI: 1.68-2.43), while a higher mindfulness score was associated with a reduced NSSI risk (OR = 0.98, 95% CI: 0.97-0.99). Path analysis showed mindfulness significantly mediated the relationship between school bullying and NSSI, accounting for 34.0% of the total association. Among all dimensions of mindfulness, mindfulness observing, describing, and acting with awareness significantly mediated the association, with acting with awareness showing the strongest mediation. The findings indicate a positive correlation between school bullying and NSSI, with mindfulness serving as a significant mediator in this association. Enhancing mindfulness among children and adolescents could be an effective strategy to mitigate school bullying associated NSSI.
