Background: There is emerging evidence that early maladaptive schemas (EMS) may be a cognitive vulnerability factor in nonsuicidal self-injury (NSSI). The current study sought to examine the relationship between EMS and NSSI history, and whether this is moderated by gender, in a community youth sample. Method: Participants were 403 Australian secondary and university students aged between 16 and 25 years, who completed a survey of NSSI history, EMS, and general emotional distress. Results: Logistic regression analysis indicated that being female, depression, and EMS scores were useful for differentiating between youth reporting NSSI history and those who did not. High levels of Defectiveness/Shame and Abandonment/Instability schema scores, and low levels of Emotional Inhibition schema scores, were associated with NSSI history. Gender did not moderate the relationships between these EMS scores and NSSI history. Conclusions: Present results suggest that aspects of the schema domain of Disconnection and Rejection are important for identifying NSSI history beyond young people's emotional distress. This provides researchers and clinicians with an opportunity to better target key EMS, especially beliefs about self-defectiveness and feelings of shame, that Abbreviations: EMS, early maladaptive schemas; NSSI, non-suicidal self-injury.may be driving the regulatory function of self-injury among youth.

| INTRODUCTIONNonsuicidal self-injury (NSSI) is increasingly recognized as a public health concern, particularly in adolescent and young adult populations. Defined as the direct intention to damage one's body tissue without suicidal intent, NSSI is associated with a number of negative mental and social health outcomes including mood, anxiety, and eating disorders (Jacobson & Gould, 2007;Laye-Gindhu & Schonert-Reichl, 2005;, as well as increased risk of suicide (Miller et al., 2013). NSSI typically emerges in early adolescence (Cipriano et al., 2017;Jacobson & Gould, 2007), with prevalence rates higher in younger populations (Plener et al., 2016). In the United States, Monto et al. (2018) reported that nearly 18% of high school students had self-injured during the previous 12 months, with similar prevalence rates reported internationally, including in Australia (Zubrick et al., 2016), the United Kingdom (Lloyd-Richardson et al., 2007), Europe (Claes et al., 2014), and Asia (You et al., 2011). Identifying those at risk of NSSI and implementing effective treatment and prevention strategies is essential to improve outcomes for this population.Although NSSI was historically believed to be a largely female behavior (e.g., Favazza & Conterio, 1989;Suyemoto & MacDonald, 1995), more recent evidence indicates that males also engage in NSSI at rates approaching those of females (
