Social and interpersonal factors relating to adolescent suicidality: a review of the literature.

This article reviews the empirical literature concerning social and interpersonal variables as risk factors for adolescent suicidality (suicidal ideation, suicidal behavior, death by suicide). It also describes major social constructs in theories of suicide and the extent to which studies support their importance to adolescent suicidality. PsychINFO and PubMed searches were conducted for empirical studies focused on family and friend support, social isolation, peer victimization, physical/sexual abuse, or emotional neglect as these relate to adolescent suicidality. Empirical findings converge in documenting the importance of multiple social and interpersonal factors to adolescent suicidality. Research support for the social constructs in several major theories of suicide is summarized and research challenges are discussed.
