Abstract

In this longitudinal study, we examined whether personality traits moderate the link between interpersonal dysfunction and suicidal behavior in a high-risk sample of 458 individuals diagnosed with borderline personality disorder. Participants were assessed annually for up to 30 years (mean number of follow-ups = 7.82). Using multilevel structural equation modeling, we examined (a) longitudinal, within-persons relationships among interpersonal dysfunction, suicidal ideation, and suicide attempts and (b) moderation of these relationships by negative affectivity and disinhibition. Negative affectivity predicted a stronger within-persons coupling between interpersonal dysfunction and suicidal ideation. Disinhibition predicted a stronger coupling between ideation and suicide attempts. Assessing negative affectivity and disinhibition in a treatment setting may guide clinician vigilance toward people at highest risk for interpersonally triggered suicidal behaviors. © The Author(s) 2022.
