Review
A systematic review on the relationship between antisocial, borderline and narcissistic personality disorder diagnostic traits and risk of violence to others in a clinical and forensic sample.
Risk assessments identify the presence of a Personality Disorder diagnosis as relevant to future violence. At present, risk assessments focus on the presence of the disorder rather than identifying key traits related to risk. Systematic searches of three databases were conducted from January 2000 until August 2014. Of 92,143, 15 studies met the inclusion criteria. A lack of empirical research was found focusing on individual traits; instead most considered PD diagnosis as a sole entity. A preliminary model has been developed detailing the link between potential interactions of diagnostic traits and risk of violence. Recommendations for future research are made.

Review
BACKGROUND
Children and adolescents with callous unemotional (CU) traits are at risk of severe and persistent antisocial behavior. It is commonly assumed that these children are difficult to treat but it has been proposed that they may benefit from being involved in interventions that go beyond typical parent training programs. This systematic review sought to answer two previously unanswered questions: do interventions involving young people reduce levels of CU traits? Do CU traits predict the effectiveness of interventions for antisocial behavior involving young people?
METHOD
Studies were included that adopted an randomized controlled trial, controlled or open trial design and that had examined whether treatment was related to reductions in CU traits or whether CU traits predicted or moderated treatment effectiveness.
RESULTS
Treatments used a range of approaches, including behavioral therapy, emotion recognition training, and multimodal interventions. 4/7 studies reported reductions in CU traits following treatment. There was a mixed pattern of findings in 15 studies that examined whether CU traits predicted treatment outcomes following interventions for antisocial behavior. In 7/15 studies, CU traits were associated with worse outcomes, although three of these studies did not provide data on baseline antisocial behavior, making it difficult to evaluate whether children with high CU traits had shown improvements relative to their own behavioral baseline, despite having the worst behavioral outcomes overall. CU traits did not predict outcomes in 7/15 studies. Finally, a single study reported that CU traits predicted an overall increased response to treatment.
CONCLUSIONS
Overall, the evidence supports the idea that children with CU traits do show reductions in both their CU traits and their antisocial behavior, but typically begin treatment with poorer premorbid functioning and can still end with higher levels of antisocial behavior. However, there is considerable scope to build on the current evidence base.

Review
OBJECTIVE
While evidence regarding associations between weight stigma and biopsychosocial outcomes is accumulating, outcomes are considered in isolation. Thus, little is known about their complex relationships. This article extends existing work by systematically reviewing the biopsychosocial consequences of stigma in adults with overweight/obesity.
METHODS
Articles were identified through Medline, CINAHL, PsycINFO, Embase, Web of Science, and Cochrane databases. Independent extraction of articles was conducted using predefined data fields, including data on biopsychosocial correlates in each study.
RESULTS
Twenty-three studies published from 2001 and addressing correlates of stigma in adults with overweight/obesity (body mass index ≥25 kg m(-2); 18-65 years) were identified. Numerous biopsychosocial correlates of weight stigma were studied, particularly in treatment-seeking individuals. Available research shows that weight stigma is consistently associated with medication non-adherence, mental health, anxiety, perceived stress, antisocial behavior, substance use, coping strategies, and social support. Biopsychosocial correlates were not considered in combination in research. Psychological correlates were well documented in comparison to biological and social correlates for each weight stigma type. There were some indications that associations are stronger once stigma is internalized.
CONCLUSIONS
While there is evidence for biopsychosocial correlates of weight stigma, these are not considered in combination in research; thus their inter-relationships are unknown. Conclusions from the review are limited by this and the small number of studies, types of designs, and variables considered.

Meta-Analysis Review
The use of anabolic-androgenic steroids (AASs) by professional and recreational athletes is increasing worldwide. The underlying motivations are mainly performance enhancement and body image improvement. AAS abuse and dependence, which are specifically classified and coded by the DSM-5, are not uncommon. AAS-using athletes are frequently present with psychiatric symptoms and disorders, mainly somatoform and eating, but also mood, and schizophrenia-related disorders. Some psychiatric disorders are typical of athletes, like muscle dysmorphia. This raises the issue of whether AAS use causes these disorders in athletes, by determining neuroadaptive changes in the reward neural circuit or by exacerbating stress vulnerability, or rather these are athletes with premorbid abnormal personalities or a history of psychiatric disorders who are attracted to AAS use, prompted by the desire to improve their appearance and control their weights. This may predispose to eating disorders, but AASs also show mood destabilizing effects, with longterm use inducing depression and short-term hypomania; withdrawal/discontinuation may be accompanied by depression. The effects of AASs on anxiety behavior are unclear and studies are inconsistent. AASs are also linked to psychotic behavior. The psychological characteristics that could prompt athletes to use AASs have not been elucidated.

Review
OBJECTIVE
To identify, by means of a systematic review, the frequency with which comorbid personality disorders (PDs) have been assessed in studies of euthymic bipolar patients.
METHODS
PubMed, ciELO and PsychINFO databases were searched for eligible articles published between 1997 and 2013. After screening 1,249 empirical papers, two independent reviewers identified three articles evaluating the frequency of PDs in patients with bipolar disorders assessed in a state of euthymia.
RESULTS
The total sample comprised 376 euthymic bipolar patients, of whom 155 (41.2%) had at least one comorbid PD. Among them, we found 87 (23.1%) in cluster B, 55 (14.6%) in cluster C, and 25 (6.6%) in cluster A. The frequencies of PD subtypes were: borderline, 38 (10.1%); histrionic, 29 (7.7%); obsessive-compulsive, 28 (7.4%); dependent, 19 (5%); narcissistic, 17 (4.5%); schizoid, schizotypal, and avoidant, 11 patients each (2.95%); paranoid, five (1.3%); and antisocial, three (0.79%).
CONCLUSION
The frequency of comorbid PD was high across the spectrum of euthymic bipolar patients. In this population, the most common PDs were those in cluster B, and the most frequent PD subtype was borderline, followed by histrionic and obsessive-compulsive.

Meta-Analysis Review
Previous research on the association between socioeconomic status (SES) and child and adolescent antisocial behaviour has produced mixed findings showing variation in the strength of association. This systematic review and meta-analysis aimed to summarise evidence on the relationship between socioeconomic status and broadly conceptualised antisocial behaviour, investigating variation across a range of antisocial subtypes and other potential moderators, including age, sex and informant. We identified 133 studies containing data suitable for effect size calculation, and 139 independent effect sizes were analysed (total N=339868). The global meta-analysis showed that lower family socioeconomic status was associated with higher levels of antisocial behaviour. Moderation analyses revealed this relationship was stronger where callous-unemotional traits were the outcome, and where antisocial behaviour was reported by parents or teachers rather than self-reported. The relationship between family SES and antisocial behaviour, however, was independent of higher-level constructs such as national income inequality. These results indicate that SES can be considered a robust correlate of broadly conceptualised antisocial behaviour but the strength of this relationship may depend on the antisocial subtype under investigation and the design of the study.

Review
BACKGROUND
With the increased knowledge of biological risk factors, interest in including this information in forensic assessments is growing. Currently, forensic assessments are predominantly focused on psychosocial factors. A better understanding of the neurobiology of violent criminal behaviour and biological risk factors could improve forensic assessments.
OBJECTIVE
To provide an overview of the current evidence about biological risk factors that predispose people to antisocial and violent behaviour, and determine its usefulness in forensic assessment.
METHODS
A systematic literature search was conducted using articles from PsycINFO, Embase and Pubmed published between 2000 and 2013.
RESULTS
This review shows that much research on the relationship between genetic predisposition and neurobiological alterations with aggression is performed on psychiatric patients or normal populations. However, the number of studies comparing offenders is limited. There is still a great need to understand how genetic and neurobiological alterations and/or deficits are related to violent behaviour, specifically criminality. Most studies focus on only one of the genetic or neurobiological fields related to antisocial and/or violent behaviour. To reliably correlate the findings of these fields, a standardization of methodology is urgently needed.
CONCLUSION
Findings from the current review suggest that violent aggression, like all forms of human behaviour, both develops under specific genetic and environmental conditions, and requires interplay between these conditions. Violence should be considered as the end product of a chain of life events, during which risks accumulate and potentially reinforce each other, displaying or triggering a specific situation. This systematic review did not find evidence of predispositions or neurobiological alterations that solely explain antisocial or violent behaviour. With better designed studies, more correlation between diverse fields, and more standardisation, it might be possible to elucidate underlying mechanisms. Thus, we advocate maintaining the current case-by-case differentiated approach to evidence-based forensic assessment.
