Turner HA, Colburn D, et al. - Researchers herein examined how the various forms of past-year maltreatment affect thoughts of self-harm and suicidal ideation and investigated the influence of gender on these effects.

• A nationally representative sample of 6,364 youth, aged 10–17 years, from three waves (2008, 2011, and 2014) of the National Survey of Children's Exposure to Violence, was interviewed on telephone to obtain data for analyses.

• Suicidal and/or self-harm ideation in the past month were recorded in over 8% of the sample; relative to males, females more frequently reported these outcomes.

• Experiencing recent emotional maltreatment, neglect, or witnessing family violence were more frequently linked with suicidal or self-harm ideation.

• The number of types of maltreatments showed a dose-response relationship with these outcomes.

• Finally, there appeared more negative effects of emotional abuse and experiencing two forms of past-year maltreatment on females vs their male counterparts.
