•We examined the independent contribution of emotion dysregulation (ED) dimensions on PD traits.•Emotional nonacceptance was transversally related to various PD traits.•Unique profiles of ED ...differentiated cluster A, B, and C PD traits.•Impulsivity explained incremental variance in schizotypal, borderline, and antisocial PD traits.•Histrionic, narcissistic, and obsessive-compulsive PD traits were related to lower ED and impulsivity.
The present study was designed to test an emotion regulation framework to understand individual differences in personality disorder (PD) traits in a non-clinical sample. Specifically, we tested whether: selected dimensions of emotion dysregulation were differentially related to PD traits; and whether emotion dysregulation and impulsivity had independent associations with PD traits. A community sample of 399 individuals (mean age = 37.91; 56.6% males) completed self-report measures of PDs, emotion dysregulation and impulsivity. Emotion dysregulation facets and impulsivity had uniform bivariate associations with PD traits, but also evidenced unique associations in multiple regression analyses. Nonacceptance of emotional responses was the emotion dysregulation dimension underlying a wide array of PD. A limited repertoire of effective emotion regulation strategies was characteristic of cluster C PD, whereas emotional unawareness distinctly predicted schizoid PD. Antisocial PD traits were uniquely related to difficulties controlling impulsive behavior when upset. Finally, histrionic, narcissistic, and obsessive-compulsive PD were related to better self-reported emotion regulation. Impulsivity further explained a significant amount of variance in schizotypal, antisocial, borderline (positively), and obsessive-compulsive PD traits (negatively). If replicated in clinical samples, our findings will support the usefulness of targeting both emotional dysregulation and impulsivity in PDs psychotherapy.

OBJECTIVE: The purpose of this study was to compare psychosocial functioning in patients with schizotypal, borderline, avoidant, or obsessive-compulsive personality disorder and patients with major ...depressive disorder and no personality disorder. METHOD: Patients (N=668) were recruited by the four clinical sites of the Collaborative Longitudinal Personality Disorders Study. The carefully diagnosed study groups were compared on an array of domains of psychosocial functioning, as measured by the Longitudinal Interval Follow-Up Evaluation-Baseline Version and the Social Adjustment Scale. RESULTS: Patients with schizotypal personality disorder and borderline personality disorder were found to have significantly more impairment at work, in social relationships, and at leisure than patients with obsessive-compulsive personality disorder or major depressive disorder; patients with avoidant personality disorder were intermediate. These differences were found across assessment modalities and remained significant after covarying for demographic differences and comorbid axis I psychopathology. CONCLUSIONS: Personality disorders are a significant source of psychiatric morbidity, accounting for more impairment in functioning than major depressive disorder alone.
A robust literature has emerged on the Dark Triad (DT) of personality—Machiavellianism (MACH), psychopathy, and narcissism. Questions remain as to whether MACH and psychopathy are distinguishable and ...whether MACH's empirical and theoretical networks are consistent. In Study 1 (N = 393; MTurk research participants), factor analyses were used to compare two‐factor (MACH and psychopathy combined + narcissism) and three‐factor models, with both fitting the data equally well. In Studies 1 and 2 (N = 341; undergraduate research participants), DT scores were examined in relation to a variety of external criteria, including self‐ and informant ratings of personality, adverse developmental experiences, and psychopathological symptoms/behaviors. In both studies, MACH and psychopathy manifested nearly identical empirical profiles and both were significantly related to disinhibitory traits thought to be antithetical to MACH. In Study 3 (N = 36; expert raters), expert ratings of the Five‐Factor Model traits prototypical of MACH were collected and compared with empirically derived profiles. Measures of MACH yielded profiles that were inconsistent with the prototypical expert‐rated profile due to their positive relations with a broad spectrum of impulsivity‐related traits. Ultimately, measures of psychopathy and MACH appear to be measuring the same construct, and MACH assessments fail to capture the construct as articulated in theoretical descriptions.

Purpose of Review
Impulsivity is a multifaceted construct and an important personality trait in various mental health conditions. Among personality disorders (PDs), especially cluster B PDs are ...affected. The aims of this review are to summarize the relevant findings of the past 3 years concerning impulsivity in cluster B PDs and to identify those subcomponents of self-reported impulsivity and experimentally measured impulse control that are most affected in these disorders.
Recent Findings
All studies referred to antisocial (ASPD) or borderline PD (BPD), and none were found for narcissistic or histrionic PD. In ASPD as well as BPD, self-report scales primarily revealed heightened impulsivity compared to healthy controls. In experimental tasks, ASPD patients showed impairments in response inhibition, while fewer deficits were found in delay discounting. BPD patients showed specific impairments in delay discounting and proactive interference, while response inhibition was less affected. However, after inducing high levels of stress, deficits in response inhibition could also be observed in BPD patients. Furthermore, negative affect led to altered brain activation patterns in BPD patients during impulse control tasks, but no behavioral impairments were found.
Summary
As proposed by the DSM-5 alternative model for personality disorders, heightened impulsivity is a core personality trait in BPD and ASPD, which is in line with current research findings. However, different components of experimentally measured impulse control are affected in BPD and ASPD, and impulsivity occurring in negative emotional states or increased distress seems to be specific for BPD. Future research could be focused on measures that assess impulsive behaviors on a momentary basis as this is a promising approach especially for further ecological validation and transfer into clinical practice.

Summary Personality disorders are common and ubiquitous in all medical settings, so every medical practitioner will encounter them frequently. People with personality disorder have problems in ...interpersonal relationships but often attribute them wrongly to others. No clear threshold exists between types and degrees of personality dysfunction and its pathology is best classified by a single dimension, ranging from normal personality at one extreme through to severe personality disorder at the other. The description of personality disorders has been complicated over the years by undue adherence to overlapping and unvalidated categories that represent specific characteristics rather than the core components of personality disorder. Many people with personality disorder remain undetected in clinical practice and might be given treatments that are ineffective or harmful as a result. Comorbidity with other mental disorders is common, and the presence of personality disorder often has a negative effect on course and treatment outcome. Personality disorder is also associated with premature mortality and suicide, and needs to be identified more often in clinical practice than it is at present.

The Diagnostic and Statistical Manual of Mental Disorders (DSM 5) classification of antisocial personality disorder (ASPD) describes individuals who engage in repetitive irresponsible, delinquent, ...and criminal behavior. The diagnosis is highly controversial, with many researchers and clinicians arguing that the category is too heterogeneous, overinclusive, and demonstrates considerable overlap with other disorders. This review focuses on recent studies that have improved our understanding of the characteristics of individuals who fit the ASPD definition by exploring how subtypes differ and how comorbid conditions influence the presentation of ASPD. In addition, we discuss research on the etiology of ASPD that has identified genetic and environmental factors that may contribute to the development and persistence of antisocial behavior, and brain imaging research that has improved our understanding of the relationships between ASPD and other psychopathology. Finally, we discuss promising preliminary research on treatment for this disorder.

Purpose of the Review
We aim to identify the most recent evidence of randomised controlled trials evaluating continued drug treatments in people with a diagnosis of BPD, review the most recent ...findings, highlight trends in terms of currently ongoing studies and comment on the overall body of evidence.
Recent Findings
We identified seven new RCTs, plus newly available data for an older RCT. Only three of these RCTs have been published in full text, while we found study data posted at trial registry platforms for the others.
Summary
The new findings do not support fluoxetine as a treatment option for suicide and self-harm prevention. A large effectiveness study did not detect beneficial effects of lamotrigine in routine care. The prevalent use of medications in BPD is still not reflected or supported by the current evidence. More research is needed regarding the most commonly used substances and substance classes, i.e. SSRIs, and quetiapine, but also with respect to people presenting with distinct comorbid conditions.

Guideline recommendations for the pharmacologic treatment of personality disorder lack consensus, particularly for emotionally unstable personality disorder (EUPD), and there is limited information ...on current prescribing practice in the United Kingdom.
To characterize the nature and quality of current prescribing practice for personality disorder across the United Kingdom, as part of a quality improvement program.
A cross-sectional survey of self-selected psychiatric services providing care for adults with personality disorder (ICD-10 criteria) was conducted. Data were collected during May 2012.
Of 2,600 patients with a diagnosis of personality disorder, more than two-thirds (68%) had a diagnosis of EUPD. Almost all (92%) patients in the EUPD subgroup were prescribed psychotropic medication, most commonly an antidepressant or antipsychotic, principally for symptoms and behaviors that characterize EUPD, particularly affective dysregulation. Prescribing patterns were similar between those who had a diagnosed comorbid mental illness and those who had EUPD alone, but the latter group was less likely to have had their medication reviewed over the previous year, particularly with respect to tolerability (53% vs 43%).
The use of psychotropic medication in EUPD in the United Kingdom is largely outside the licensed indications. Whether the treatment target is identified as intrinsic symptoms of EUPD or comorbid mental illness may depend on the diagnostic threshold of individual clinicians. Compared with prescribing for EUPD where there is judged to be a comorbid mental illness, the use of off-label medication for EUPD alone is less systematically reviewed and monitored, so opportunities for learning may be lost. Treatment may be continued long term by default.
The authors examined the stability of schizotypal (STPD), borderline (BPD), avoidant (AVPD) and obsessive-compulsive (OCPD) personality disorders (PDs) over 2 years of prospective multiwave ...follow-up. Six hundred thirty-three participants recruited at 4 collaborating sites who met criteria for 1 or more of the 4 PDs or for major depressive disorder (MDD) without PD were assessed with semistructured interviews at baseline, 6, 12, and 24 months. Lifetable survival analyses revealed that the PD groups had slower time to remission than the MDD group. Categorically, PD remission rates range from 50% (AVPD) to 61% (STPD) for dropping below diagnostic threshold on a blind 24-month reassessment but range from 23% (STPD) to 38% (OCPD) for a more stringent definition of improvement. Dimensionally, these findings suggest that PDs may be characterized by maladaptive trait constellations that are stable in their structure (individual differences) but can change in severity or expression over time.
