This study reports the prevalence of self-injurious behavior and suicide attempts among college students in Indonesia and examines risk factors distinguishing between 3 groups: self-injury with suicide attempt, non-suicidal self-injury, and non-self-injury. Self-report questionnaires measuring self-injury and suicide attempts, negative mood regulation expectancies (NMRE), depression, and childhood trauma were administered to 314 students. Of participants, 38% had deliberately injured themselves; among those, 21% also reported a suicide attempt. The 3 groups differed significantly on NMRE, depression, and child neglect. More self-injury and suicide attempts were associated with weaker NMRE and greater depression and child neglect.
