Criteria For Antisocial Personality Disorder Research Articles

Update on Antisocial Personality Disorder.

Antisocial personality disorder (ASPD) is a characterized by lifelong or recurrent behavioral problems that begin in childhood or early adolescence. This communication provides an overview on ASPD including findings from recent reviews and new research. With regard to DSM-5's Section III Alternative Model of Personality Disorder criteria for ASPD, advocates point to the broader symptom coverage and harmonization with ICD-11; yet critics point to the lack of evidence for improved outcomes. A new report shows that antisocial individuals age faster than non-antisocial peers. ASPD has high heritability and newer molecular studies have found intriguing linkages to genes associated with crucial brain regions. A mentalization-based therapy model has been developed and early work shows promise. ASPD is common, widespread, and disruptive to individuals, families, and society. Chronic and lifelong, ASPD typically lessens in severity with advancing age. Assessment rests on the individual's history because there are no diagnostic tests. ASPD likely results from an interplay ofgenetic and environmental factors. Brain imaging studies have linked cortical dysfunction to antisocial behavior in crucial brain regions. Medication is sometimes targeted at the individual's aggression and irritability, but a more rational approach is to target co-occurring disorders. Cognitive-behavioral therapy and mentalization-based therapy models have been developed and are being studied.

Development and Validation of the Online Antisocial Personality Scale (OAPS) Using the DSM-5 Criteria for Antisocial Personality Disorder (APD)

Recent studies have consistently demonstrated that antisocial behaviors occur in online environments. Although online antisocial behavior has a long history, it appears to have become more widespread in recent years due to the widespread use of online social networks. Although there are established criteria and instruments assessing antisocial behavior there are few examining such behavior online. Therefore, the present study aimed to develop the Online Antisocial Personality Scale (OAPS). The OAPS was developed using the diagnostic criteria for antisocial personality disorder in DSM-5. The OAPS assesses antisocial behavior in online environments. The present study comprised 447 adolescents (219 girls and 228 boys) from four different samples. The measures used included the Online Antisocial Personality Scale (OAPS), E-Bullyıng Scale (E-BS), and Personality Belief Questionnaire-Short Form (PBQ-STF). The structural validity of OAPS was investigated with Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and criterion validity. When validity and reliability analysis of the OAPS are considered as a whole, it is concluded that the OAPS is a valid and reliable scale that assesses online antisocial personality among adolescents.

Psychiatrists as forensic authorities: evaluation of dangerous habitual offenders in West Germany during the 1960s - the Helmut Hoinka case.

Preventive detention for highly dangerous habitual offenders has been in force in Germany for 90 years. The necessity of this measure is hotly debated from a legal perspective. However, the assignment of preventive detention is largely determined by the opinion of medical experts. This article discusses the role of medical experts and the issues they face in evaluating the dangerousness of habitual offenders using the case of the marriage swindler Helmut Hoinka, prosecuted several times in the Federal Republic of Germany in the 1960s. Helmut Hoinka's case was chosen for analysis because of the rare opportunity to access detailed materials that allowed us to follow in detail the reasoning of the medical experts who evaluated Hoinka: medical reports stored in the Gerd Huber Archive at the University of Ulm, and Hoinka's court case from the State Archive of North Rhine-Westphalia. To examine these sources, we implemented the historical-critical method. The medical experts who evaluated Hoinka were aware of the defendant's criminal record prior to the evaluation, which was a source of bias. In addition, the criteria for classifying the offender as a dangerous habitual offender were open to a wide range of interpretations. Hoinka's high level of intelligence was negatively emphasized. Some test results were considered unreliable because it was assumed that Hoinka had manipulated his answers. Personal value judgments were allowed in assessing Hoinka's personality. Hoinka's criminal behavior was considered a medical symptom of psychopathy because it violated general moral and social norms. The medical reports of both experts showed that the psychiatrists believed in the genetic nature of psychopathy and criminal behavior. Their criminological prognosis was fully supported by the court in imposing the sentence. Challenges to Hoinka's criminological prognosis were the experts' personal biases, their belief in the theory of genetic predisposition to crime, the lack of clear criteria for antisocial personality disorder, and the absence of forensic recommendations for "psychopathic" criminals. The experts' opinion on Hoinka's criminal predisposition was crucial to the imposition of the sentence.

Antisocial personality traits relationship with behaviours and beliefs on COVID-19 containment measures: Investigation in a large Brazilian sample.

In the COVID-19 context, traits associated with antisociality can decrease concern and awareness about the potential harmfulness of the virus. This study investigated associations of pathological traits of antisocial personality disorder (ASPD) with behaviours and beliefs linked to COVID-19 containment measures. The sample consisted of 2230 Brazilian adults who answered ASPD-related facets of the Personality Inventory for DSM-5 and a questionnaire regarding adherence to COVID-19 containment measures. We applied the DSM-5 ASPD criteria to divide the sample into antisocial and non-antisocial groups. Our findings suggest that individuals meeting the criteria for ASPD tend to exhibit reduced compliance with pandemic control measures and lower adherence to hygiene practices. Moreover, sex, income, and age should be considered potential covariates in research investigating the relationship between antisocial traits and adherence to COVID-19 preventive measures. Altogether, our findings highlight ASPD traits' role in the predisposition to lack of prosocial behaviours of adherence to COVID-19 containment measures.

Genome-wide association study of antisocial personality disorder diagnostic criteria provides evidence for shared risk factors across disorders.

While progress has been made in determining the genetic basis of antisocial behaviour, little progress has been made for antisocial personality disorder (ASPD), a condition that often co-occurs with other psychiatric conditions including substance use disorders, attention deficit hyperactivity disorder (ADHD), and anxiety disorders. This study aims to improve the understanding of the genetic risk for ASPD and its relationship with other disorders and traits. We conducted a genome-wide association study (GWAS) of the number of ASPD diagnostic criteria data from 3217 alcohol-dependent participants recruited in the UK (UCL, N = 644) and the USA (Yale-Penn, N = 2573). We identified rs9806493, a chromosome 15 variant, that showed a genome-wide significant association ( Z -score = -5.501, P = 3.77 × 10 -8 ) with ASPD criteria. rs9806493 is an eQTL for SLCO3A1 (Solute Carrier Organic Anion Transporter Family Member 3A1), a ubiquitously expressed gene with strong expression in brain regions that include the anterior cingulate and frontal cortices. Polygenic risk score analysis identified positive correlations between ASPD and smoking, ADHD, depression traits, and posttraumatic stress disorder. Negative correlations were observed between ASPD PRS and alcohol intake frequency, reproductive traits, and level of educational attainment. This study provides evidence for an association between ASPD risk and SLCO3A1 and provides insight into the genetic architecture and pleiotropic associations of ASPD.

Cascades From Early Adolescent Impulsivity to Late Adolescent Antisocial Personality Disorder and Alcohol Use Disorder

PurposeThe behavioral disinhibition model (BDM) posits that a liability toward impulsivity evident by early adolescence underlies the coemergence of antisocial behavior and alcohol use (i.e., problem behaviors) in early-adolescence to mid-adolescence, but that the subsequent development of these problem behaviors (rather than impulsivity itself) predicts the emergence of antisocial personality disorder (APD) and alcohol use disorder (AUD) in late adolescence. The present study was designed to test these predictions of the BDM from early to late adolescence. MethodsWe used five-year longitudinal self-report data from the Philadelphia Trajectory Study that was collected from 2006–2012. Mediational analyses were performed using the Random Intercept Cross-lagged Panel Model, which enables the detection of within-person predictions of changes in problem behaviors during adolescence. The sample was ethnically and socioeconomically diverse, including 364 urban US community youth (at baseline: Mage = 13.51(.95); 49.1% female). ResultsConsistent with the BDM, mediational analyses revealed that changes in early adolescent impulsivity predicted late adolescent APD and AUD criteria, mediated by changes in mid-adolescent alcohol use and conduct problems. DiscussionInterventions targeting impulsivity in early adolescence could potentially halt the cascading chain of events leading to both late adolescent APD and AUD by decelerating growth in antisocial behavior and alcohol use during early-adolescence to mid-adolescence. From mid-adolescence to late-adolescence, the consequences of early impulsivity, especially involvement in antisocial behaviors, become a more relevant predictor of both APD and AUD rather than impulsivity itself.

An Interpretative Phenomenological Analysis on the Experience of Probation Officers in Managing People With Antisocial Personality Disorder.

People who are managed by the National Probation Service and convicted of high risk offences will often meet criteria for antisocial personality disorder and have complex psychosocial needs; this group of people present with high risk behavior which may professionals have been reluctant to work with in the past who are associated with higher rates of recidivism. This study investigated the experiences of probation officers in managing people who meet the criteria for Anti Social Personality Disorder. Semi structured interviews were conducted with six participants to capture their experiences of working with this population, the challenges they faced, and coping mechanisms employed, through analysis using Interpretative Phenomenological Analysis (IPA). Three superordinate themes were identified which revealed participants internal feeling, strategies employed, and external challenges. They spoke about internal negative feelings, specifically feeling controlled, having mistrust, a lack of confidence, being overwhelmed with emotion, and experiencing a fear of risk behaviors. Other themes involved external pressures as well as different coping responses. Implications are discussed to help probation officers to understand this population, for the organization to support staff to work with challenging behaviors and prevent burn out, to enable positive outcomes, and for potentially reducing reoffending.

The clinical course of antisocial behaviors in men and women of three racial groups

AimsTo describe the clinical course and symptom profile of DSM-IV Antisocial Personality Disorder (ASPD) and the syndrome of Adult Antisocial Behavior Syndrome (AABS) and determine if they differ based on sex and race. MethodsUsing questions from a validated semi-structured interview, data were gathered from 2 independent family studies in: 1) American Indians (AI), and 2) European Americans (EA), African Americans (AA) (total n = 7171) who reported antisocial symptoms. ResultsWithin these two samples 1148 (16%) individuals met ASPD criteria, 1932 (27%) met adult ASPD but not childhood conduct disorder (CD) (i.e., AABS). The clinical course of the antisocial behaviors studied did not differ based on race or sex; however, individual symptom counts, and age of onsets of those symptoms, were significantly different across the groups. Women reported fewer symptoms and at an older age (less fights, school suspensions/expulsions, arrests or jail time), than men but were more likely to run away from home. Those with ASPD vs. AABS had more symptoms overall including not experiencing remorse. AA and AI participants and those with ASPD, had more symptoms, and were more likely to be suspended/expelled from school and arrested at a younger age than EA. ConclusionIn these select samples, the order and sequence of antisocial behaviors did not differ by race, AASB vs. ASPD, or sex; however individual symptom endorsement did, with men (vs. women), those with ASPD (vs. AABS), AI and AA (vs. EA) reporting more suspensions/expulsions from school and arrests. This suggests further study of the possible role of race and sex in the consequences associated with antisocial syndromes is warranted.

Deconstructing childhood conduct and adult antisocial criteria for the diagnosis of antisocial personality disorder

Antisocial personality disorder (ASPD) is a serious psychiatric disorder that can be incapacitating and costly to individuals and society. The ASPD diagnosis has 2 main components, childhood conduct problems and adult antisocial behaviors, with specific age requirements. The nosological effects of these criteria on population subgroups defined by these aspects of the criteria have not been fully explored. Data for ASPD were analyzed for 3,498 individuals in the St Louis, Missouri, site of the Epidemiologic Catchment Area study of general population psychiatric disorders collected in the early 1980s using structured diagnostic interviews for DSM-III criteria. Effects of the criteria on population subgroups defined by various combinations of the criteria were examined. Earlier-onset conduct disorder was more severe than later-onset childhood conduct disorder, with more total childhood and adult symptoms and negative psychosocial adult outcomes (substance use disorders, criminality, and homelessness). Three subgroups with adult antisocial behaviors (differentiated by no conduct disorder, later-onset conduct disorder, and earlier-onset conduct disorder meeting ASPD criteria) were similar in numbers of adult antisocial symptoms, but the ASPD subgroup had more negative psychosocial adult outcomes. These findings provide evidence for and against reconsideration of the 15-year age-of-onset requirement for conduct symptoms in ASPD criteria.

What lies underneath: The genetics and neurobiology of psychopathy

IntroductionPsychopathy is a personality disorder characterized by lack of empathy, grandiosity, an impulsive lifestyle and antisociality. Anti-social personality disorder (ASPD) and psychopathy are distinct concepts presenting different criteria. Most people with a diagnosis of psychopathy also meet criteria for ASPD while the reverse is not true. Along the years there has been an increasing interest in investigating genetic and neurobiological factors.ObjectivesTo analyze the neurobiological factors involved in psychopathy and anti-social personality disorder according to the scientific knowledge available.MethodsReview of scientific literature via PubMed search, using the terms “anti-social personality disorder”, “biology or etiology or pathophysiology and psychopathy”.ResultsThe strongest evidence base for a genetic pathway is associated with the low-expression variant of the Monoamine Oxidase-A (MAO-A) which is linked to the X chromosome. Other genetic factors involve the 5-HTT gene, dopamine receptor genes (DRD4 and DRD2) and genetic polimorfisms at SNAP25 t-snare protein, OXT gene and the CNR1 and FAAH cannabinoid receptor gene. Structural differences in the brain have been noticed such as reduced gray matter volume in the orbitofrontal cortex, gray matter volume reductions in the mid-anterior insula and left anterior temporal cortex, subtle reductions in gray matter volume across several paralimbic and limbic areas.ConclusionsThere is considerable evidence regarding various possible underlying neurobiological processes in psychopathy although it is insufficient to suggest a single biological etiology and environmental influences cannot be excluded from a complete understanding of this disorder. The neurobiological correlates found hold promise for new research and treatment.

Age bias in the criteria for antisocial personality disorder

The prevalence of antisocial personality disorder (ASPD) decreases with age. As such, research regarding ASPD typically focuses on children and younger adults. The apparent age-specific prevalence of ASPD may be due, in part, to diagnostic criteria informed by research excluding older adults. The present study sought to better understand the manifestation of ASPD in older adults and investigate potential age bias in the diagnostic criteria. Item response theory methods were used to the diagnostic criteria for ASPD with data from the National Epidemiologic Survey on Alcohol and Related Conditions Wave III. The measurement of three ASPD criteria showed uniform differential item functioning (DIF), suggesting that older adults were less likely to endorse the item than younger adults despite having the same level of underlying personality disorder. The items with DIF are related to the following criteria for ASPD: Failure to conform to social norms with respect to lawful behaviors as indicated by repeatedly performing acts that are grounds for arrest (3 items with DIF); irritability and aggressiveness, as indicated by repeated physical fights or assaults (1 item with DIF); and consistent irresponsibility, as indicated by repeated failure to sustain consistent work behavior or honor financial obligations (1 item with DIF). Results of the present study can be used to inform the development of criteria that better capture the age-specific experience of this disorder. Improved criteria will result in increased diagnostic accuracy, systematic estimation of the prevalence, improved assessments, and more effective treatment options for this complex population.

Incremental validity of the Psychopathy Checklist-Revised above and beyond the diagnosis of antisocial personality disorder regarding recidivism in sexual offenders

PurposeThe diagnostic criteria of the Antisocial Personality Disorder (ASPD) overlaps greatly with the Lifestyle and Antisocial facets of the Hare Psychopathy Checklist-Revised (PCL-R), whereas the Interpersonal and Affective facets seem to differentiate between antisocial and psychopathic offenders. Previous studies investigated either the ASPD diagnosis or psychopathy measured with the PCL-R, but not the combination of both in sexual offenders. The present study tested three hypotheses that PCL-R scores are incrementally predictive above and beyond the ASPD diagnosis regarding general recidivism, non-sexual violent recidivism, and sexual recidivism. MethodsWe performed Cox regression modeling with two-fold cross validation, using a training sample (n = 755) and a testing sample (n = 368) of adult male sexual offenders from Austria. Average time-at-risk was 10.13 years. ResultsThe PCL-R scores predicted general and violent recidivism after the diagnosis of the ASPD was controlled for. The Lifestyle and Antisocial facets, in particular, were incremental. Sexual recidivism could not be predicted. ConclusionsThe current results support the use of the PCL-R in applied sexual offender assessment in addition to general clinical diagnostic procedures due to its incremental validity, despite a large overlap between the diagnostic criteria of ASPD and the PCL-R concept of psychopathy.

Associations of alcohol use, mental health and socioeconomic status in England: Findings from a representative population survey

BackgroundAlcohol use and mental health problems often co-occur, however, little is known about how this varies by type of mental health problem and to what extent associations are explained by socioeconomic status (SES). Our study examined the prevalence and associations of non-drinking, hazardous use, and harmful/probable dependence in individuals who do and do not meet criteria for different mental health problems and whether associations remained after adjustment for SES. MethodsA secondary analysis of an English dataset, 2014 Adult Psychiatric Morbidity Survey (N = 7,218), was conducted. The Alcohol Use Disorder Identification Test was used to categorise participants as non-drinking, low risk, hazardous use and harmful/probable dependence. Mental health problems were screened using a range of validated tools. Multinomial logistic regression analyses were used to address study aims. ResultsThe prevalence of non-drinking, hazardous and harmful/probable dependence was higher among those meeting criteria for a mental health problem. After adjustment for SES, non-drinking was most common in those meeting criteria for probable psychotic disorder (MOR = 3.42, 95 %CI = 1.74–6.70), hazardous use in those meeting criteria for anti-social personality disorder (MOR = 2.66, 95 %CI = 1.69–4.20) and harmful/probable dependence in those meeting criteria for borderline personality disorder (MOR = 9.77, 95 % CI = 4.81–19.84). ConclusionsThere were marked increases in the odds of reporting both non-drinking and harmful drinking among those meeting criteria for a mental health problem, particularly more severe problems. Our findings indicate that the relationship between alcohol and mental health is more complex and comorbid alcohol and mental health problems should be treated in parallel with access to both services.

Predicting Suicidal Behavior Without Asking About Suicidal Ideation: Machine Learning and the Role of Borderline Personality Disorder Criteria.

Identifying predictors contributing to suicide risk could help prevent suicides via targeted interventions. However, using only known risk factors may not yield accurate enough results. Furthermore, risk models typically rely on suicidal ideation, even though people often withhold this information. This study examined the contribution of various predictors to the accuracy of six machine learning models for identifying suicidal behavior in a prison population (n=353), including borderline personality disorder (BPD) and antisocial personality disorder (APD) criteria, and compared how excluding data about suicidal ideation affects accuracy. Results revealed that gradient tree boosting accurately identified individuals with suicidal behavior, even without relying on questions about suicidal ideation (AUC=0.875, F1=0.846). Furthermore, the model maintained this accuracy with only 29 predictors. Meeting five or more diagnostic criteria of BPD was an important risk factor for suicidal behavior. APD criteria, in the presence of other predictors, did not substantially improve accuracy. Additionally, it may be possible to implement a decision tree model to assess individuals at risk of suicide, without focusing upon suicidal ideation. These findings highlight that modern classification algorithms do not necessarily require information about suicidal ideation for modeling suicide and self-harm behavior.

Executive function, attention, and memory deficits in antisocial personality disorder and psychopathy

Antisocial personality disorder (ASPD) and psychopathy attempt to represent individuals demonstrating callousness and disregard for others. ASPD has been criticized for capturing a heterogeneous population whilst missing the essence of the diagnosis by neglecting interpersonal/affective deficits which measures of psychopathy include. This heterogeneity in operationalizations has led to diverse findings without clear understanding of what characterizes this broader population. This study sought to clarify the neuropsychological profiles of ASPD and psychopathy. The Cambridge Neuropsychological Test Assessment Battery was administered to 85 adult male offenders in a personality disorder secure service and to 20 healthy controls. Of patients with ASPD, 46% met criteria for psychopathy. Of those with psychopathy, 89% met criteria for ASPD. There were two sets of comparisons: ASPD versus other personality disorders versus controls and psychopathy versus other personality disorders versus controls. ASPD showed deficits across executive functions, visual short-term and working memory, and attention (compared with controls). Psychopathy showed deficits limited to attention, complex planning, inhibitory control, and response reversal. Response reversal and visual search deficits appeared specific to ASPD and psychopathy versus other personality disorders and may underpin antisocial traits. Additional deficits in inhibitory control and working memory appeared to distinguish ASPD from other personality disorders.

AN ANALYSIS ON ANTISOCIAL PERSONALITY DISORDER OF KEVIN IN “WE NEED TO TALK ABOUT KEVIN MOVIE DIRECTED” BY LYNNE RAMSAY

The aim of this analysis is to know and understand the criteria, causes, influence, characters and moral messages of Kevin in Analysis on Antisocial Personality Disorder of Kevin in “We Need to talk about Kevin Movie Directed by Lynne Ramsay”. This method uses descriptive qualitative analysis. The analytical results obtained are: (1) Criteria of antisocial personality disorder of Kevin namely among the other things deceitfulness, irritability, aggressiveness, reckless, disregard for safety of his own self or for others and lack of remorse. (2) The causes of antisocial personality disorder on Kevin is less responsive (genetic) and neglect of family on Kevin (Environment). (3) Kevin’s behaviour influencing the others is posing of a threat and (4) Moral message that people should anticipate with antisocial personality disorder is that people should not hurt the person and should communicate with him very well. As a result, Kevin has the characters of aggressiveness, easily lying and can injure others without feeling any guilt.

The antisocial personality disorder in the Brazilian movies

ABSTRACT Objective: The antisocial personality disorder (APD) is one theme of interest for psychiatry/mental health students and professionals. The access to psychopathology aspects by means of movies is able to improve the understanding about these disorders. This study aimed at evaluates the frequency of APD and of its diagnostic criteria in the Brazilian cinema for teaching purposes. Methods: The method consisted of survey sampling (for convenience, once the study is extracted from another greater project); use of a diagnostic instrument and analysis of the results. Results: 44.73% of the personalities were diagnosed with APD. All the diagnostic criteria for APD were present. The most frequent criterion was the practice of illegal acts. Impulsivity was associated with aggressiveness in 29.4% of the cases and with the use of psychoactive substances in almost 30% of the cases. 35.3% of the characters had a premature and violent death. Conclusion: The research enabled the identification of APD diagnostic criteria in the Brazilian cinema. Many scenes were able to represent the diagnosis clearly. The data proved to be sufficient in indicate the potentiality of the material as a didactic and pedagogical foundation.

Estudio psicométrico del Cuestionario de Detección del Trastorno de Conducta (CDTC)

In Mexico an elevated rate of violence exists and it has been increasing over the years. A high percentage of these violent individuals fulfill the criteria of Antisocial Personality Disorder in their adult life or Conduct Disorder (CD) in their childhood or adolescence. The behavior of these individuals is aggressive and there is a violation of the rules and the rights of others. Since CD carries serious consequences and can progress to an antisocial disorder, it is advisable to treat children and adolescents as soon as possible. Therefore, it is necessary to have an instrument for the diagnosis of CD in Mexico. In order to have a reliable tool, the DSM-IV questionnaire was analyzed for the diagnosis of the conduct disorder (Previously dissocial disorder in DSM-IV-TR) with a sample of 305 high school students, 155 female and 150 male students from the city of Morelia, Michoacan (Mexico). It was concluded that the best solution was 1 factor in terms of its internal structure and a Cronbach alpha value of .87. All 14 items were suitable, Pearson's correlations were made with other measures, obtaining positive and moderate correlations with the Plutchik Impulsivity Scale, the Beck Depression Inventory and the Knight CRAFFT scale (Assess risk of substance abuse), and there was no correlation with the State-Trait Anxiety Inventory. Results support that this instrument possesses adequate psychometric properties to be administrated on the city of Morelia, Michoacan (Mexico).

Examining the Association Between Psychiatric Disorders and Cocaine Binges: Results From the COSMO Study.

Although cocaine binges and mental health problems have both been identified as significant risk factors for different health hazards, little is known about the relationship between mental health and cocaine binging. Hence, the aim of this study is to examine the association between psychiatric disorders and cocaine binge. Participants were part of a prospective cohort study of individuals who either smoke or inject cocaine. The dependent variable, namely a cocaine binge within the past month, was defined as the repetitive use of large quantities of cocaine until the individual was unable to access more of the drug or was physically unable to keep using. Psychiatric disorders were assessed using the Composite International Diagnostic Interview and the Diagnostic Interview Schedule questionnaires. Logistic regression models were performed to examine the association between cocaine binging and psychiatric disorders, adjusting for potential confounders. Of the 492 participants, 24.4% reported at least 1 cocaine binging episode during the prior month. Among the study population, 48.0% met the criteria for antisocial personality disorder (ASPD), 45.5% for anxiety disorders, and 28.2% for mood disorders. Participants with ASPD were more likely to binge (adjusted odds ratio 1.73, 95% confidence interval 1.10-2.73), whereas those with a mood disorder were not. The association between anxiety disorders and cocaine binging was significant only in univariate analyses. ASPD increased the odds of reporting cocaine binge in our study population. These results highlight the need for a better understanding of the specific dimensions of ASPD that contribute to the increased risk of unsafe drug use behaviors.

A Psychometric Evaluation of the DSM-IV Criteria for Antisocial Personality Disorder: Dimensionality, Local Reliability, and Differential Item Functioning Across Gender.

This study aims at evaluating the psychometric properties of the antisocial personality disorder (ASPD) criteria in a large sample of patients, most of whom had one or more personality disorders (PD). PD diagnoses were assessed by experienced clinicians using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Axis II PDs. Analyses were performed within an item response theory framework. Results of the analyses indicated that ASPD is a unidimensional construct that can be measured reliably at the upper range of the latent trait scale. Differential item functioning across gender was restricted to two criteria and had little impact on the latent ASPD trait level. Patients fulfilling both the adult ASPD criteria and the conduct disorder criteria had similar latent trait distributions as patients fulfilling only the adult ASPD criteria. Overall, the ASPD items fit the purpose of a diagnostic instrument well, that is, distinguishing patients with moderate from those with high antisocial personality scores.
