title: Childhood stress leads to later suicidality via its effect on cognitive functioning.
abstract: The present study examined the etiology of suicidal behavior from cognitive and developmental perspectives in a sample of 181 suicidal and nonsuicidal college students. We hypothesized that cognitive functioning would serve as a mediator between early life events and suicidal behavior. The present study examined child maltreatment, family instability, and poor general family environment as early negative life events, and examined self-esteem, locus of control, hopelessness, and problem-solving deficits as cognitive factors. In addition, individuals' perceived social support before age 18 and current social support and life stress were also examined in relation to the preceding variables. A series of structural equation analyses indicated that early negative life events have a mild impact on suicidal behavior, but a stronger impact on cognitive deficits, which in turn have a strong impact on suicidal behavior.
