This cross-sectional study of youth in an urban area examined the prevalence and psychosocial correlates associated with reporting both self-harm and suicide attempts. The findings show that the demographic and psychosocial factors associated with both suicide attempt and self-harm vary significantly. Girls and students in the younger grade levels were most likely to report both self-harm and suicide attempts. Moreover the findings show that there is a significant overlap in the modifiable risk factors associated with self-harm and suicide attempt that can be targeted for future research and prevention strategies. More specifically, binge drinking, weapon carrying, child maltreatment, depression, impulsivity and lower levels of parental support were specifically associated with both self-harm and suicide attempt.
