Suicide is a serious health problem as it is currently the third leading cause of death for teenagers between the ages of 15 and 24 years. Depression, which is also a serious problem for adolescents, is the most significant biological and psychological risk factor for teen suicide. Alcohol use remains extremely widespread among today's teenagers and is related to both suicidality and depression. Suicidality refers to the occurrence of suicidal thoughts or suicidal behavior. The consensus in empirical research is that mental disorders and substance abuse are the most important risk factors in both attempted and completed adolescent suicide. Therefore, it is incumbent upon researchers to identify the factors that can lead to their prevention among today's youth. This review compiles the existing literature on suicidality, depression, and alcohol use among adolescents spanning over the past 15 years. Both Problem Behavior Theory and Stresscoping Theory can explain the relationships among suicidality, depression and alcohol use. The prevention of suicidality is critical, especially during the early school years, when it is associated with depression and alcohol use. Suicidality, depression and alcohol use are three phenomenon that noticeably increase in adolescence marking this time period as an ideal opportunity for prevention efforts to commence. Future empirical work is needed that will further assess the impact of adolescent depression and alcohol use on suicidality. In sum, this review of empirical research highlights critical results and limitations, as well as indicates a need for continued efforts in preventing suicidality, depression, and alcohol use among adolescents.

The perceived outcomes of drug use were studied in a sample of high-risk adolescents. Participants' self-generated responses provided the actual words they used to describe drug outcomes as well as associative frequency norms valuable for future research. The authors also compared outcomes in terms of class of outcome (positive vs. negative) and class of drug (alcohol, marijuana, cigarettes, cocaine, speed, and LSD). Although the studied drugs have divergent pharmacological effects, participants self-generated some of the same outcomes (e.g., relaxation) across some of the drugs. In addition, outcomes self-generated as positive outcomes were very rarely also self-generated as negative outcomes. Finally, regressions revealed that self-generated responses were not predicted by ethnicity, gender, or previous drug use. Many drug use outcomes thus appeared to be available in memory regardless of previous drug use or other characteristics.

The relationships between risk factors and outcomes in adolescents participating in the Drug Abuse Treatment Outcome Studies for Adolescents (DATOS-A) were examined. The study included 292 admissions to nine outpatient drug-free (ODF) and 418 admissions to eight residential (RES) programs. Assessments were administered at intake into treatment and 12 months following discharge. For ODF participants, (a) severity of drug use predicted less retention in treatment, and (b) family drug involvement predicted more alcohol use after treatment. For RES participants, (a) family drug involvement and criminal involvement predicted less treatment retention, and (b) conduct disorder predicted more marijuana use at follow-up. The findings underscore the need for intervention strategies that address the intrapsychic and interpersonal functioning of drug-abusing adolescents to improve their behavioral outcomes.
