This chapter summarizes findings from follow-up studies of adolescent suicide attempters, and reviews four major areas: continued psychiatric disturbance, rates of repeat attempts, rates of completed suicide, and treatment compliance. Many studies present data on combined adolescent and adult samples, but adult findings are probably not generalizable to adolescents. The chapter highlights data on general adjustment, academic functioning, social functioning, behavior, and psychopathology. There is a high level of continued behavioral dysfunction among adolescent suicide attempters, suggesting that, for most, the suicide attempt is not an isolated problem. The risk factors for repeat attempts include gender, severity of the initial attempt, affective and conduct disorders, and family conflict. In the literature on adult suicidal behavior, the use of survival analysis has been recommended in order to clarify risk factors. To improve the cost-effectiveness of interventions, studies which provide a more in-depth investigation of the postattempt course are also needed.
