Identifying Bridge Symptoms Between Borderline Personality Disorder and Posttraumatic Stress Disorder: A Network Analysis From a National Cohort.

Objective: Borderline personality disorder (BPD) and posttraumatic stress disorder (PTSD) share common risk factors, including exposure to traumatic events. We aim to estimate networks of DSM-IV BPD and PTSD to describe the interactions between the symptoms of these 2 disorders and identify bridging symptoms between the 2 diagnoses that may play critical roles in their co-occurrence. Methods: We performed a network analysis of data from the second wave of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC 2004-2005), a nationally representative sample of the US adult population. We calculated network stability using a bootstrap method and centrality measures for each symptom across 3 different network estimations. Results: The networks were very stable. The symptom "chronic feelings of emptiness" was the most central in the BPD network. The symptoms "feeling of intense fear or horror" and "recurrent and intrusive memories of the traumatic event" were the most central in the PTSD network. The symptoms "self aggression," "severe dissociation," "chronic feelings of emptiness," and "feelings of detachment" had significantly higher bridge expected influence than most other symptoms in the network in both the full sample and the subsample of participants who responded to all PTSD and BPD symptoms. Conclusion: Self-aggression, chronic feelings of emptiness, dissociation symptoms, and feelings of detachment represent bridge symptoms between BPD and PTSD. These symptoms could potentially trigger and perpetuate the manifestations of one disorder in the presence of the other. Targeting these symptoms might allow better prevention and management of both disorders.

Comorbidity of borderline personality disorder and posttraumatic stress disorder in the U.S. population.

While placed on different axes of the DSM classification system, borderline personality disorder (BPD) and posttraumatic stress disorder (PTSD) have important relationships with trauma, and overlap between these disorders has long been recognized. The current study is the first to examine comorbidity of PTSD and BPD in a large nationally representative sample using a reliable and valid method of assessing Axis I and II mental disorders. Data came from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) Wave II (N = 34,653; response rate 70.2%). Multiple regression models were used to examine differences in psychopathology, traumatic events and health-related quality of life across individuals with PTSD alone (n = 1820), BPD alone (n = 1290) and those with comorbid PTSD-BPD (n = 643). The lifetime prevalence of PTSD and BPD were 6.6% and 5.9%, respectively. Of individuals with BPD, 30.2% were also diagnosed with PTSD, whereas 24.2% of individuals with PTSD were also diagnosed with BPD. Individuals with comorbid PTSD-BPD had a poorer quality of life, more comorbidity with other Axis I conditions, increased odds of a lifetime suicide attempt, and a higher prevalence of repeated childhood traumatic events than individuals with either condition alone. These results show that PTSD and BPD have a high degree of lifetime co-occurrence but are not entirely overlapping. Their concurrence is associated with poorer functioning compared to either diagnosis alone, emphasizing the clinical utility of diagnosing both conditions. Future research should explore the determinants of having either or both diagnoses with an aim toward improved identification, prevention, and intervention.

Affect intensity and lability: the role of posttraumatic stress disorder symptoms in borderline personality disorder.

Emotion dysregulation is likely a core psychological process underlying the heterogeneity of presentations in borderline personality disorder (BPD) and is associated with BPD symptom severity. Emotion dysregulation has also been independently associated with posttraumatic stress disorder (PTSD), a disorder that has been found to co-occur with BPD in 30.2% of cases in a nationally representative sample. However, relatively little is known about the specific relationships between emotion dysregulation and PTSD among those diagnosed with BPD. The purpose of this study was to evaluate relationships between PTSD symptom severity and negative affect intensity and affective lability among individuals with BPD. Participants were 67 individuals diagnosed with BPD (79% women; M(age) = 38, SD = 10), who reported one or more DSM-IV PTSD Criterion A events. Hierarchical multiple regression analyses indicated that when examined concurrently with BPD symptom severity, PTSD symptom severity, but not BPD symptom severity, was related to negative affect intensity and affective lability. Re-experiencing symptoms uniquely predicted affective lability, and hyperarousal symptoms uniquely predicted negative affect intensity, lending additional support to emerging literature linking re-experiencing and hyperarousal symptoms with emotion dysregulation. PTSD symptom severity among individuals with a BPD diagnosis is related to elevations in emotion dysregulation. It is important to evaluate whether early treatment of PTSD symptoms provided concurrently with BPD treatment leads to enhanced improvements in emotion regulation among individuals with co-occurring PTSD and BPD.
