Suicidal behaviors among children and adolescents

Résumé

This chapter examines the prevalence of suicidal ideation and behavior in children and adolescents as well as a number of risk factors that contribute to suicidal behavior. Depression, disruptive behavior disorders, and substance use disorders place adolescents at high risk for suicidal behavior, with comorbidity further increasing risk. Cognitive factors, especially hopelessness and poor problem solving, have also been related to suicidal behavior among adolescents. A prior suicide attempt is one of the best predictors of both a repeat attempt and eventual completed suicide. Research on families Indicates that suicidal behavior is transmitted through families. Although abnormalities in the serotonergic system have not been consistently linked to suicidal behavior, genetic and neurobiologic studies suggest that impulsive aggression may be the mechanism through which decreased serotonergic activity is related to suicidal behavior. Findings from intervention studies are modest and indicate the need for substantially more theory-driven treatment research.
