Emotion dysregulation and maladaptive personality traits in adolescents with suicidal behavior and self-harm: differences by level of care

EMOTION DYSREGULATION AND MALADAPTIVE PERSONALITY TRAITS IN ADOLESCENTS WITH SUICIDALITY AND NON-SUICIDAL SELF-INJURY: DIFFERENCES ACROSS LEVELS OF CARE

Interpersonal sensitivity predicts suicidal symptoms in inpatients, whereas negative affectivity predicts self-harm regardless of level of care.

The aim of this study was to examine the associations of emotion dysregulation and maladaptive personality traits with suicidal behavior and nonsuicidal self-injury (NSSI) in adolescents across different levels of care. A total of 142 adolescents aged 13–17 receiving care in a child and adolescent psychiatry unit were assessed, with the sample divided into inpatient (n=79) and day hospital (DH; n=63) groups. Emotion dysregulation was measured using the RIPoSt-Y across three dimensions (affective instability, emotional reactivity, and interpersonal sensitivity), and maladaptive personality traits were measured using the short form of the PID-5 for adolescents across five domains (negative affectivity, detachment, antagonism, disinhibition, and psychoticism); the presence of suicidal behavior and NSSI was analyzed using binary logistic regression. Inpatient status (B=6.35, p=0.031) and interpersonal sensitivity (B=0.19, p=0.042) were significant predictors of suicidal behavior. A significant interaction was found between negative affectivity and level of care; negative affectivity predicted suicide risk only in day hospital patients (DH: B=0.159, p=0.029; inpatients: B=-0.007, p=0.772). Negative affectivity was the only significant predictor of NSSI (B=0.07, p=0.037). In conclusion, emotion dysregulation appears to be more prominent in suicidal symptoms among inpatients, whereas maladaptive personality traits are more prominent among those receiving outpatient care; NSSI appears to be associated with negative affectivity regardless of level of care. These findings highlight the importance of tailoring treatment to the level of care and specific psychopathological dimensions.
