The prevalence of self-harm (in the past year) was 20.3% (23.9% for girls and 16.4% for boys). Moreover, among those who reported self-harm, 38.2% had also attempted suicide in the past year). Findings based on the four-level outcome variable show that 7.5% of participants reported both self-harm and suicide attempt, 2.2% of participants reported suicide attempt only, and 12.4% of participants reported self-harm only. Findings from the chi-square analyses and t-tests show that all independent variables examined were significantly associated with self-harm and suicide attempt (Table 1). Moreover, patterns of the outcome variables varied significantly by sex, grade level and race/ethnicity (Table 1). More specifically, girls, and students with Hispanic ethnicity were most likely to report both suicide attempt and self-harm in the past year. Additionally, students who reported binge drinking, illicit drug use, weapon carrying child maltreatment were also more likely to report both suicide attempt and self-harm. Similarly, students who reported less social support, higher levels of depression, higher levels of impulsivity, lower levels of self-efficacy, lower levels of parental support and lower levels of parental monitoring were also more likely to report both suicide attempt and self-harm.
