Suicide-Related Concerns as a Mediator Between Physical Abuse and Self-Harm Behaviors in College Students.

Abstract

Multiple studies have found correlations between history of abuse and self-harm behaviors, but few have examined potential mediators. Studying suicide-related concerns as a mediator in this relationship could inform the interpersonal theory of suicide by identifying acquired capability as a necessary component in self-harm behavior. This study examined the link between childhood physical abuse, self-injurious behaviors, and suicide-related concerns in young adults. It was hypothesized that more physical abuse and fewer suicide-related concerns would predict self-harm behaviors, and that suicide-related concerns would mediate this relationship. A sample of 212 university students completed self-report measures that assessed self-harm behavior history, reasons for living, and childhood physical abuse. Results supported the hypothesis that more instances of abuse and less concern about pain and death were significantly associated with greater self-harm history. Suicide-related concerns also mediated the relationship between physical abuse and self-harm behaviors. These results support recent theories that habituation to painful and provocative events is an important mechanism in explaining why people engage in self-injurious acts, and provides initial evidence for cognitive mediators between physical abuse and self-harm.
