Gender differences in a clinical sample of patients with borderline personality disorder
ABSTRACT The aim of the study was to investigate gender differences and similarities in patients with borderline personality disorder (BPD) with respect to Axis I comorbidity, Axis II comorbidity, general psychopathology (Symptom Checklist 90-Revised), and dimensional personality traits (NEO-Personality-Inventory Revised [NEO-PI-R] and the Dimensional Assessment of Personality Profile Basic questionnaire [DAPP-BQ]). Fifty-seven men and 114 women with BPD were included in the study. Regarding Axis I and II disorders in an exploratory analysis, men with BPD more often fulfilled the diagnostic criteria for binge eating disorder, antisocial personality disorder, narcissistic personality disorder, and conduct disorder in childhood, whereas women had higher frequencies of bulimia nervosa, posttraumatic stress disorder, and panic disorder with agoraphobia. After correcting for multiple tests, only the gender differences in narcissistic and antisocial personality disorder remained significant. In the SCL-90-R profile, no significant gender differences could be identified. In the exploratory analysis of the dimensional personality traits, women showed higher rates on the NEO-PI-R main factors (Neuroticism and Agreeableness) compared to men. In the DAPP-BQ profile, men reached higher sores on the main factor, Dissocial Behavior. When correcting for multiple tests, gender differences still existed for Neuroticism and Dissocial Behavior. Our results argue for gender differences in Axis I and II comorbidity and dimensional personality traits in BPD. However, in general, more similarities than differences were shown in this study.

ABSTRACT: Anxiety disorders are highly prevalent among individuals with borderline personality disorder, with comorbidity rates of up to 90%. Anxiety disorders have been found to reduce the likelihood of achieving remission from borderline personality disorder over time and to increase the risk of suicide and self-injury in this population. Evidence-based treatments for borderline personality disorder have not sufficiently focused on targeting anxiety disorders, and their effects on these disorders are either limited or unknown. Conversely, evidence-based treatments for anxiety disorders typically exclude suicidal, self-injuring, and seriously comorbid patients, thereby limiting their generalizability to individuals with borderline personality disorder. To address these limitations, recent research has begun to emerge focused on developing and evaluating treatments for individuals with co-occurring borderline personality disorder and anxiety disorders, specifically posttraumatic stress disorder (PTSD), with promising initial results. However, there is a need for additional research in this area, particularly studies evaluating the treatment of anxiety disorders among high-risk and complex borderline personality disorder patients.05/2013; 5:15.

ABSTRACT: Due to the higher diagnostic prevalence of borderline personality disorder (BPD) in females, there exists a dearth of literature on the manifestations of BPD in men and minimal information on male developmental trajectories to the disorder. To identify precursors of BPD in males, surveys were administered to parents about their BPD male offspring and non-BPD male siblings. Questions covered aspects of probands' lives from infancy to late adolescence. BPD offspring were identified through self-reported clinical diagnoses and standardized diagnostic criteria embedded within the survey. A total of 263 male offspring (97 meeting strict criteria for BPD and 166 non-BPD siblings) were studied. The authors found that parents describe the early emergence of a constellation of symptoms in their BPD sons that include separation anxiety starting in infancy, body image concerns in childhood, and impulsivity, emptiness, and odd thinking in adolescence. This trajectory differs from the developmental course found in females diagnosed with BPD.Journal of personality disorders 06/2013; DOI:10.1521/pedi_2013_27_111 · 3.08 Impact Factor

ABSTRACT: The heritability of borderline personality (BP) features has been established in multiple twin and family studies. Using data from the borderline subscale of the Personality Assessment Inventory Borderline Features Scale (PAI-BOR) collected in two Dutch cohorts (N=7125), the Netherlands Twin Register and The Netherlands Study of Depression and Anxiety, we show that heritability of the PAI-BOR total score using genome-wide single-nucleotide polymorphism (SNPs) is estimated at 23%, and that the genetic variance is substantially higher in affect instability items compared with the other three subscales of the PAI-BOR (42.7% vs non-significant estimates for self-harm, negative relations and identity problems). We present results from a first genome-wide association study of BP features, which shows a promising signal on chromosome 5 corresponding to SERINC5, a protein involved in myelination. Reduced myelination has been suggested as possibly having a role in the development of psychiatric disorders characterized by lack of social interaction. The signal was confirmed in a third independent Dutch cohort drawn from the Erasmus Rucphen Family study (N=1301). Our analyses were complemented by investigating the heterogeneity that was implied by the differences in genetic variance components in the four subscales of the PAI-BOR. These analyses show that the association of SNPs tagging SERINC5 differs substantially across the 24 items of the PAI-BOR. Further, using reverse regression we showed that the effects were present only in subjects with higher scores on the PAI-BOR. Taken together, these results suggest that future genome-wide analyses can benefit substantially by taking into account the phenotypic and genetic heterogeneity of BP features.Molecular Psychiatry advance online publication, 27 August 2013; doi:10.1038/mp.2013.109.Molecular Psychiatry 08/2013; 19(8).
