The role of DSM-5 borderline personality symptomatology and traits in the link between childhood trauma and suicidal risk in psychiatric patients.

ABSTRACT:

Background

Childhood traumas appear to be linked to suicidal behavior. However, the factors that mediate between these two phenomena are not sufficiently understood. Recent findings suggest that borderline personality disorder (BPD) may explain some of the association.

Method

The present study investigated the potential mediating role of BPD symptomatology and traits between reported childhood trauma and suicidal risk in adult psychiatric outpatients (N?=?124). BPD symptomatology was measured with DSM-5 Section II criterion-counts (SCID-II; Structured Clinical Interview for DSM-IV Axis II), whereas BPD traits were measured with specified DSM-5 Section III traits (PID-5; Personality Inventory for DSM-5). Childhood traumas were self-reported (CTQ; Childhood Trauma Questionnaire), whereas level of suicidal risk was measured with a structured interview (MINI Suicidality Module; Mini International Neuropsychiatric Interview). Mediation effects were tested by bias-corrected (10.000 boot-strapped samples) confidence intervals.

Results

BPD features account for a considerable part of the cross-sectional association between childhood trauma and level of suicidal risk, even when controlling for the influence of gender, age, and educational level. This finding remained stable when testing the model without the suicidality-related BPD criterion and PID-5 items. DSM-5 Section II BPD criterion-counts explained 67% of the total effect, whereas DSM-5 Section III BPD traits accounted for 82% of the total effect. The specific DSM-5 Section III trait facets of "Depressivity" (52%) and "Perceptual Dysregulation" (37%) accounted for most of this effect.

Conclusions

The findings provide preliminary support for the proposed mediation model indicating that BPD features may help explain relations between childhood trauma and elevated suicidal risk in adult life, in particular for DSM-5 Section III personality traits of depressivity (e.g., pessimism, guilt, and shame) and perceptual dysregulation (e.g., dissociation). To reduce the suicidal risk among those with a history of childhood trauma, BPD features (including "Depressivity" and "Perceptual Dysregulation") might be an important target of assessment, risk management, and treatment. However, other factors are likely to be involved, and a longitudinal and more large-scale design is warranted for a conclusive test of mediation.

Project description:BackgroundBorderline Personality Disorder (BPD) is a potentially severe personality disorder, characterized by difficulties in emotion regulation and control of behaviors. It is often associated with non-suicidal self-injury (NSSI). Borderline personality features have also been linked to body modifications (BMs). However, the prevalence of BMs, the link between BMs and NSSI, and between BMs and several psychopathology dimensions (e.g. borderline severity, emotion regulation, impulsivity …) remains understudied in patients with BPD. This study aims to fill this gap, and to provide further evidence on the link between NSSI and BMs.MethodsWe used data from a psychiatric outpatient center located in Switzerland (n = 116), specialized in the assessment and treatment of BPD patients. Patients underwent several semi-structured interviews and self-report psychometric scales at the arrival, and the data were retrospectively analyzed.ResultsWe found that 70.69% of the patients had one piercing or more, and 69.83% were tattooed. The total score of body modifications and the total number of piercings score of piercings were significantly positively associated with NSSI and the SCID BPD total score. The association with the SCID score was mainly driven by the "suicide and self-damaging behaviors" item and the "chronic feeling of emptiness" item. A significant association was found between total number of piercings and emotion dysregulation. On the other hand, the self-reported percentage of body covered by tattoos score was specifically associated with the sensation seeking subscale of the UPPS-P.ConclusionThis study provides evidence on the prevalence of BMs in BPD patients, and on the link between BMs and NSSI in this population, suggesting a role of emotion regulation in the link between both constructs. These results also suggests that tattoos and piercings may be differentially linked to specific underlying psychological mechanisms. This calls for further considerations of body modifications in the assessment and care of BPD patients.

Project description:BackgroundIn the development of borderline personality disorder (BPD) both genetic and environmental factors have important roles. The characteristic affective disturbance and impulsive aggression are linked to imbalances in the central serotonin system, and most of the genetic association studies focused on serotonergic candidate genes. However, the efficacy of dopamine D2 receptor (DRD2) blocking antipsychotic drugs in BPD treatment also suggests involvement of the dopamine system in the neurobiology of BPD.MethodsIn the present study we tested the dopamine dysfunction hypothesis of impulsive self- and other-damaging behaviors: borderline and antisocial traits were assessed by Structured Clinical Interview for Diagnosis (SCID) for DSM-IV in a community-based US sample of 99 young adults from low-to-moderate income families. For the BPD trait analyses a second, independent group was used consisting of 136 Hungarian patients with bipolar or major depressive disorder filling out self-report SCID-II Screen questionnaire. In the genetic association analyses the previously indicated polymorphisms of the catechol-O-methyl-transferase (COMT Val158Met) and dopamine transporter (DAT1 40 bp VNTR) were studied. In addition, candidate polymorphisms of the DRD2 and DRD4 dopamine receptor genes were selected from the impulsive behavior literature.ResultsThe DRD2 TaqI B1-allele and A1-allele were associated with borderline traits in the young adult sample (p = 0.001, and p = 0.005, respectively). Also, the DRD4 -616 CC genotype appeared as a risk factor (p = 0.02). With severity of abuse accounted for in the model, genetic effects of the DRD2 and DRD4 polymorphisms were still significant (DRD2 TaqIB: p = 0.001, DRD2 TaqIA: p = 0.008, DRD4 -616 C/G: p = 0.002). Only the DRD4 promoter finding was replicated in the independent sample of psychiatric inpatients (p = 0.007). No association was found with the COMT and DAT1 polymorphisms.ConclusionsOur results of the two independent samples suggest a possible involvement of the DRD4 -616 C/G promoter variant in the development of BPD traits. In addition, an association of the DRD2 genetic polymorphisms with impulsive self-damaging behaviors was also demonstrated.
