title: Non-violent and violent forms of childhood abuse in the prediction of suicide attempts: Direct or indirect effects through psychiatric disorders?
abstract: Childhood abuse is linked to suicide. Potential pathways include the increased risk for the development of psychiatric disorders and the contribution of abuse to suicide capability. The current study compared the effects of childhood non-violent and violent abuse in the prediction of suicide attempts, and examined the potential mediated effects of psychiatric disorders.
  
  
  
  Data from the National Comorbidity Surveys were obtained. At baseline, assessments of childhood non-violent abuse (e.g., parental verbal abuse) and violent abuse (e.g., parental physical abuse, relative rape) were obtained. We also assessed for other adverse childhood experiences, baseline suicidal behaviors, and psychiatric disorders. At the ten-year follow-up, we assessed for psychiatric disorders and suicide attempts that had occurred over time.
  
  
  
  Both non-violent and violent abuse predicted attempts, though participants experiencing violent abuse had significantly higher rates. Bootstrapped mediation analyses determined that the influence of non-violent abuse on suicide attempts was indirect, and exerted its influence through the psychiatric disorders that occurred during the ten-year follow-up.
  
  
  
  The study relied on retrospective reports of childhood abuse. Further, we could not clearly determine the temporal order of the psychiatric disorders and suicide attempts occurring over follow-up.
  
  
  
  Different mechanisms may underlie the pathway between violent and non-violent abuse and suicide attempts. Verbal abuse may lead to negative cognitive styles and psychiatric disorders associated with suicidality; violent abuse may contribute to the capacity for suicide. Interventions may need to be specifically tailored to meet the distinct needs of individuals who have experienced past childhood abuse.
