Suicidality, depression, and alcohol use among adolescents: a review of empirical findings

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 Stress-coping 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.
