Clinical and Psychosocial Predictors of Suicide Attempts and Nonsuicidal Self-Injury in the Adolescent Depression Antidepressants and Psychotherapy Trial (ADAPT)

The authors assessed whether clinical and psychosocial factors in depressed adolescents at baseline predict suicide attempts and nonsuicidal self-injury over 28 weeks of follow-up. METHOD: Participants were 164 adolescents with major depressive disorder taking part in the Adolescent Depression Antidepressants and Psychotherapy Trial (ADAPT). Clinical symptoms, family function, quality of current personal friendships, and suicidal and nonsuicidal self-harm were assessed at baseline. Suicidal and nonsuicidal self-harm thoughts and behaviors were assessed during 28 weeks of follow-up.

High suicidality, nonsuicidal self-injury, and poor family function at entry were significant independent predictors of suicide attempts over the 28 weeks of follow-up. Nonsuicidal self-injury over the follow-up period was independently predicted by nonsuicidal self-injury, hopelessness, anxiety disorder, and being younger and female at entry.
