Data from 390 high school students were collected to examine potential differences between adolescents who had attempted suicide and those who engaged in self-injurious behavior on measures of depression, suicidal ideation, and attitudes toward life and death. Significant differences were found between controls and the self-harm groups on all dependent variables. A significant difference on attitudes toward life was found between the self-injury and suicide attempt groups. Post-hoc regression analyses showed that measures of depression, suicide ideation, and attitudes towards life predicted participants' self-harm categorization. These findings provide preliminary evidence that self-injurious behavior is different from attempted suicide among a community sample of adolescents.
