Schlagbaum P, Tissue JL, Sheftall AH, et al. - In the present study, the researchers sought to explore the role of peer influence on adolescent suicidal ideation and attempts within youth seeking emergency care or outpatient mental health services, as well as to ascertain if affiliation with peers reporting suicidal thoughts/behaviors was correlated with an adolescent’s own suicidal ideation and/or suicide attempt beyond individual risk factors. One hundred and eighteen adolescents, aged 13 to 18 years, were selected from the emergency department and outpatient mental health clinics at a large, metropolitan children’s hospital. Affiliation with peers reporting suicidal thoughts/behaviors was associated with an adolescent’s own history of suicide attempt. Understanding peer affiliation may be an important resource for identifying and preventing youth suicidal behavior. Evidence-based programs that focus on and use peer influence could be extremely beneficial to prevention efforts.
