The association of childhood trauma with suicidality in adult psychiatric patients: The mediating role of NSSI and the moderating role of self‐esteem

Abstract

AbstractBackgroundThe contribution of specific childhood trauma subtypes to suicidal thoughts and the associated mechanisms remains unclear, particularly in psychiatric patients.MethodsFace‐to‐face interviews were conducted with 449 psychiatric patients aged 18–73. Childhood trauma, self‐esteem, nonsuicidal self‐injury (NSSI), and suicidality were assessed retrospectively. Regression and moderated mediation model were employed to examine these relationships.ResultsEmotional and sexual abuse were independently associated with suicidality. Female patients reported higher levels of emotional and sexual abuse, lower self‐esteem, and a heightened risk of suicide. Self‐esteem moderated the links between childhood trauma and NSSI, as well as between NSSI and suicidality. NSSI served as a mediator between childhood trauma and suicidality.ConclusionsSuicide prevention in mentally ill patients should involve targeted programs addressing specific childhood trauma. Additionally, psychological interventions to enhance self‐esteem and assist individuals engaging in NSSI behavior are crucial.
