Concept: Personality disorders
Psychopathy is a personality disorder associated with a profound lack of empathy. Neuroscientists have associated empathy and its interindividual variation with how strongly participants activate brain regions involved in their own actions, emotions and sensations while viewing those of others. Here we compared brain activity of 18 psychopathic offenders with 26 control subjects while viewing video clips of emotional hand interactions and while experiencing similar interactions. Brain regions involved in experiencing these interactions were not spontaneously activated as strongly in the patient group while viewing the video clips. However, this group difference was markedly reduced when we specifically instructed participants to feel with the actors in the videos. Our results suggest that psychopathy is not a simple incapacity for vicarious activations but rather reduced spontaneous vicarious activations co-existing with relatively normal deliberate counterparts.

Objectives: There are ongoing uncertainties in the relationship between obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder (OCPD). This study aimed to test the proposition that OCPD may be a marker of severity of OCD by comparing groups of OCD individuals with and without OCPD on a number of variables. Method: A total of 148 adults with a principal diagnosis of OCD were administered the Mini International Neuropsychiatric Interview, Yale-Brown Obsessive-Compulsive Scale, Sheehan Disability Scale, Vancouver Obsessional Compulsive Inventory and Symptom Checklist 90-Revised. Participants with a DSM-IV diagnosis of OCPD were compared with those without OCPD. Results: Some 70 (47.3%) participants were diagnosed with OCPD. The groups of participants with and without OCPD did not differ significantly with respect to any of the demographic variables, clinician-rated severity of OCD, levels of disability and mean age of onset of OCD. All self-rated OCD symptom dimensions except for contamination and checking were significantly more prominent in participants with OCPD, as were all self-rated dimensions of psychopathology. Participants with OCPD had significantly more frequent hoarding compulsions and obsessions involving a need to collect and keep objects. Of Axis I disorders, only panic disorder was significantly more frequent in participants with OCPD than in those without OCPD. Conclusions: A high frequency of OCPD among individuals with OCD suggests a strong, although not necessarily a unique, relationship between the two conditions. This finding may also be a consequence of the blurring of the boundary between OCD and OCPD by postulating that hoarding and hoarding-like behaviours characterise both disorders. Results of this study do not support the notion that OCD with OCPD is a marker of clinician-rated severity of OCD. However, individuals with OCPD had more prominent OCD symptoms, they were more distressed and exhibited various other psychopathological phenomena more intensely, which is likely to complicate their treatment.
OBJECTIVE The authors assessed the defensive functioning of 290 patients with borderline personality disorder and compared it with that of 72 patients with other forms of axis II psychopathology over 16 years of prospective follow-up. They also assessed the relationship between time-varying defenses and recovery from borderline personality disorder. METHOD The Defense Style Questionnaire, a self-report measure with demonstrated criterion validity and internal consistency, was initially administered at study entry. It was readministered at eight contiguous 2-year follow-up periods. RESULTS Borderline patients had significantly lower scores than axis II comparison subjects on one mature defense mechanism (suppression) and significantly higher scores on seven of the other 18 defenses studied: one neurotic-level defense (undoing), four immature defenses (acting out, emotional hypochondriasis, passive aggression, and projection), and two image-distorting/borderline defenses (projective identification and splitting). Over the follow-up period, borderline patients showed significant improvement on 13 of the 19 defenses studied, with significantly higher scores over time on one mature defense (anticipation) and significantly lower scores on two neurotic defenses (isolation and undoing), all immature defenses, and all image-distorting/borderline defenses except primitive idealization. In addition, four time-varying defense mechanisms were found to predict time to recovery: humor, acting out, emotional hypochondriasis, and projection. CONCLUSIONS Taken together, these results suggest that the longitudinal defensive functioning of borderline patients is distinct and improves substantially over time. They also suggest that immature defenses are the best predictor of time to recovery.
The link between early traumatic experiences of abuse/neglect and criminal behaviour has been widely demonstrated. Less is known, however, about the relationship between these experiences and the development of psychopathic personality.

Intermittent Explosive Disorder (IED), as described in DSM-5, is the categorical expression of pathological impulsive aggression. Previous work has identified neurobiological correlates of the disorder in patterns of frontal-limbic brain activity and dysregulation of serotonergic neurotransmission. Given the importance of short and long range white matter connections of the brain in social and emotional behavior, studies of white matter connectivity in impulsive aggression are warranted. Diffusion tensor imaging (DTI) studies in the related conditions of antisocial and borderline personality disorder have produced preliminary evidence of disturbed white matter connectivity in these disorders, but to date there have been no DTI studies in IED. 132 male and female adults between the ages of 19 and 55 underwent Turboprop-DTI on a 3 Tesla MRI scanner. 42 subjects had IED, 40 were normal controls, and 50 were clinical psychiatric controls with psychiatric disorders without IED. All subjects were free of alcohol, psychotropic medications, or drugs of abuse. The diffusion tensor was calculated in each voxel and maps of fractional anisotropy (FA) were generated. Tract-based spatial statistics (TBSS) were used to compare FA along the white matter skeleton between the three subject groups. IED was associated with lower FA in two clusters located in the superior longitudinal fasciculus (SLF) when compared to the psychiatric and healthy controls. Impulsive aggression and borderline personality disorder, but not psychopathy or antisocial personality disorder, was associated with lower FA in the two clusters within the SLF.In conclusion, IED was associated with lower white matter integrity in long range connections between the frontal and temporo-parietal regions.Neuropsychopharmacology accepted article preview online, 20 May 2016. doi:10.1038/npp.2016.74.
Psychopathy is a condition that has long captured the public imagination. Newspaper column inches are devoted to murderers with psychopathic features and movies such as No Country for Old Men and We Need to Talk About Kevin focus on characters who are exceptionally cold and callous. Psychopathy is in fact a personality disorder characterised by lack of empathy and guilt, shallow affect, manipulation of other people and severe, premeditated and violent antisocial behaviour. Individuals with psychopathy generate substantial societal costs both as a direct financial consequence of their offending behaviour and lack of normal participation in working life, but also in terms of the emotional and psychological costs to their victims.
Psychopathy is a personality disorder characterised by atypical moral behaviour likely rooted in atypical affective/motivational processing, as opposed to an inability to judge the wrongness of an action. Guilt is a moral emotion believed to play a crucial role in adherence to moral and social norms, but the mechanisms by which guilt (or lack thereof) may influence behaviour in individuals with high levels of psychopathic traits are unclear. We measured neural responses during the anticipation of guilt about committing potential everyday moral transgressions, and tested the extent to which these varied with psychopathic traits. We found a significant interaction between the degree to which anticipated guilt was modulated in the anterior insula and interpersonal psychopathic traits: anterior insula modulation of anticipated guilt was weaker in individuals with higher levels of these traits. Data from a second sample confirmed that this pattern of findings was specific to the modulation of anticipated guilt and not related to the perceived wrongness of the transgression. These results suggest a central role for the anterior insula in coding the anticipation of guilt regarding potential moral transgressions and advance our understanding of the neurocognitive mechanisms that may underlie propensity to antisocial behaviour.
Theory and research suggest that narcissism plays an important role in perpetration of sexual aggression. As narcissism is a multidimensional construct, our objective was to clarify the relation between perpetration and three aspects of narcissism. College men (N = 234) completed the Narcissistic Personality Inventory (NPI), Narcissistic Personality Disorder (NPD) subscale of the Structured Clinical Interview for DSM Disorders-II (SCID-N) Personality Questionnaire, and Hypersensitive Narcissism Scale (HSNS). Perpetrators had higher scores on NPD traits, which were also associated with frequent perpetration. HSNS scores were only associated with perpetration via alcohol and/or drugs. Only the maladaptive facets of NPI narcissism correlated with perpetration. Narcissism seems to have been understudied in nonincarcerated perpetrators.
The criteria for personality disorders in Section II of DSM-5 have not changed from those in DSM-IV. Therefore, the diagnosis of Section II narcissistic personality disorder (NPD) will perpetuate all of the well-enumerated shortcomings associated with the diagnosis since DSM-III. In this article, we will briefly review problems associated with Section II NPD and then discuss the evolution of a new model of personality disorder and the place in the model of pathological narcissism and NPD. The new model was intended to be the official approach to the diagnosis of personality pathology in DSM-5, but was ultimately placed as an alternative in Section III for further study. The new model is a categorical-dimensional hybrid based on the assessment of core elements of personality functioning and of pathological personality traits. The specific criteria for NPD were intended to rectify some of the shortcomings of the DSM-IV representation by acknowledging both grandiose and vulnerable aspects, overt and covert presentations, and the dimensionality of narcissism. In addition, criteria were assigned and diagnostic thresholds set based on empirical data. The Section III representation of narcissistic phenomena using dimensions of self and interpersonal functioning and relevant traits offers a significant improvement over Section II NPD.

OBJECTIVE The authors compared the effectiveness of 50 sessions of schema therapy with clarification-oriented psychotherapy and with treatment as usual among patients with cluster C, paranoid, histrionic, or narcissistic personality disorder. METHOD A multicenter randomized controlled trial, with a single-blind parallel design, was conducted between 2006 and 2011 in 12 Dutch mental health institutes. A total of 323 patients with personality disorders were randomly assigned (schema therapy, N=147; treatment as usual, N=135; clarification-oriented psychotherapy, N=41). There were two cohorts of schema therapy therapists, with the first trained primarily with lectures and the second primarily with exercises. The primary outcome was recovery from personality disorder 3 years after treatment started (assessed by blinded interviewers). Secondary outcomes were dropout rates and measures of personality disorder traits, depressive and anxiety disorders, general psychological complaints, general and social functioning, self-ideal discrepancy, and quality of life. RESULTS A significantly greater proportion of patients recovered in schema therapy compared with treatment as usual and clarification-oriented psychotherapy. Second-cohort schema therapists had better results than first-cohort therapists. Clarification-oriented psychotherapy and treatment as usual did not differ. Findings did not vary with specific personality disorder diagnosis. Dropout was lower in the schema therapy and clarification-oriented psychotherapy conditions. All treatments showed improvements on secondary outcomes. Schema therapy patients had less depressive disorder and higher general and social functioning at follow-up. While interview-based measures demonstrated significant differences between treatments, differences were not found with self-report measures. CONCLUSIONS Schema therapy was superior to treatment as usual on recovery, other interview-based outcomes, and dropout. Exercise-based schema therapy training was superior to lecture-based training.
