DSM-IV Criteria For Personality Disorder Research Articles

Exploring the predictive validity of personality disorder criteria.

We tested the predictive validity of personality disorder (PD) indicators at different levels of aggregation, ranging from general PD severity to PD syndrome scales to individual PD criteria. We compared the predictive validity of models on these levels based on interview data on all 78 DSM-IV PD criteria, by using 19 outcome scales in three different samples (N = 651, N = 552, and N = 1,277). We hypothesized that criteria of personality pathology yield a significant increase in predictive validity compared with scales that are aggregated at the syndrome- or general severity-level. We assessed out of sample performance of predictive models in a repeated cross-validation design using regularized linear regression and regression forest algorithms. We observed no significant difference in predictive performance between models trained at the item-level and models trained on scale-level data. We further tested the predictive performance of the trained linear models across samples on outcome measures shared between samples and inspected models for criteria-level information they relied on to make predictions. Our results suggest that little predictive variance is lost when interview items assessing DSM-IV PD criteria are aggregated to dimensional PD scales.

The structure of genetic and environmental influences on normative personality, abnormal personality traits, and personality disorder symptoms.

Can the structure of genetic and environmental influences on normative personality traits (NPTs), abnormal personality traits (APTs), and DSM-IV criteria for personality disorders (PD) fit a high or low congruence model positing, respectively, close or more limited etiologic continuity? Exploratory factor analysis was applied to transformed correlation matrices from Cholesky twin decompositions obtained in OpenMx. In 2801 adult twins from the Norwegian Institute of Public Health Twin Panel, NPTs and APTs were assessed by self-report using the Big Five Inventory (BFI) and PID-5-Norwegian Brief Form (PID-5-NBF), respectively. PDs were assessed at interview using the Structured Interview for DSM-IV Personality (SIDP-IV). The best model yielded three genetic and three unique environmental factors. Genetic factors were dominated, respectively, by (i) high loadings on nearly all PDs and NPT/APT neuroticism and compulsivity, (ii) negative loadings on NPT agreeableness/conscientiousness and positive loadings on APT/PD measures of antisocial traits, and (iii) negative loadings on NPT extraversion and histrionic PD, and positive loadings on APT detachment and schizoid/avoidant PD. Unique environmental factors were dominated, by (i) high loadings on all PDs, (ii) high loadings on all APT dimensions and NPT neuroticism, and (iii) negative loadings on NPT extraversion and positive loadings on NPT detachment/avoidant PD. Two genetic and one environmental common factor were consistent with a high congruence model while one genetic and two environmental factors were more supportive of a low congruence model. The relationship between genetic and environmental influences on personality assessed by NPTs, APTs, and PDs is complex and does not fit easily into a low or high congruence model.

A Twin Study of Normative Personality and DSM-IV Personality Disorder Criterion Counts: Evidence for Separate Genetic Influences.

Both normative personality and DSM-IV personality disorders have been found to be heritable. However, there is limited knowledge about the extent to which the genetic and environmental influences underlying DSM personality disorders are shared with those of normative personality. The aims of this study were to assess the phenotypic similarity between normative and pathological personality and to investigate the extent to which genetic and environmental influences underlying individual differences in normative personality account for symptom variance across DSM-IV personality disorders. A large population-based sample of adult twins was assessed for DSM-IV personality disorder criteria with structured interviews at two waves spanning a 10-year interval. At the second assessment, participants also completed the Big Five Inventory, a self-report instrument assessing the five-factor normative personality model. The proportion of genetic and environmental liabilities unique to the individual personality disorder measures, and hence not shared with the five Big Five Inventory domains, were estimated by means of multivariate Cholesky twin decompositions. The median percentage of genetic liability to the 10 DSM-IV personality disorders assessed at wave 1 that was not shared with the Big Five domains was 64%, whereas for the six personality disorders that were assessed concurrently at wave 2, the median was 39%. Conversely, the median proportions of unique environmental liability in the personality disorders for wave 1 and wave 2 were 97% and 96%, respectively. The results indicate that a moderate-to-sizable proportion of the genetic influence underlying DSM-IV personality disorders is not shared with the domain constructs of the Big Five model of normative personality. Caution should be exercised in assuming that normative personality measures can serve as proxies for DSM personality disorders when investigating the etiology of these disorders.

The association between personality disorders with alcohol use and misuse: A population-based twin study

BackgroundA clearer understanding of the etiological overlap between DSM-IV personality disorders (PDs) and alcohol use (AU) and alcohol use disorder (AUD) is needed. To our knowledge, no study has modeled the association between all 10 DSM-IV PDs and lifetime AU and AUD. The aim of the present study is to identify which PDs are most strongly associated with the phenotypic, genetic, and environmental risks of lifetime AU and AUD, and to determine if these associations are stable across time. MethodsParticipants were Norwegian twins assessed at two waves. At Wave 1, 2801 twins were assessed for all 10 DSM-IV PD criteria, lifetime AU, and DSM-IV AUD criteria. At Wave 2, six of the 10 PDs were again assessed along with AU and AUD among 2393 twins. Univariate and multiple logistic regressions were run. Significant predictors were further analyzed using bivariate twin Cholesky decompositions. ResultsBorderline and antisocial PD criteria were the strongest predictors of AU and AUD across the two waves. Despite moderate phenotypic and genetic correlations, genetic variation in these PD criteria explained only 4% and 3% of the risks in AU, and 5% to 10% of the risks in AUD criteria, respectively. At Wave 2, these estimates increased to 8% and 23% for AU, and 17% and 33% for AUD. ConclusionsAmong a large Norwegian twin sample, borderline and antisocial PD criteria were the strongest predictors of the phenotypic and genotypic liability to AU and AUD. This effect remained consistent across time.

Democratic therapeutic community treatment for personality disorder: randomised controlled trial.

Democratic therapeutic community (DTC) treatment has been used for many years in an effort to help people with personality disorder. High-quality evidence from randomised controlled trials (RCTs) is absent. To test whether DTC treatment reduces use of in-patient services and improves the mental health of people with personality disorder. An RCT of 70 people meeting DSM-IV criteria for personality disorder (trial registration: ISRCTN57363317). The intervention was DTC and the control condition was crisis planning plus treatment as usual (TAU). The primary outcome was days of in-patient psychiatric treatment. Secondary outcomes were social function, mental health status, self-harm and aggression, attendance at emergency departments and primary care, and satisfaction with care. All outcomes were measured at 12 and 24 months after randomisation. Number of in-patient days at follow-up was low among all participants and there was no difference between groups. At 24 months, self- and other directed aggression and satisfaction with care were significantly improved in the DTC compared with the TAU group. DTC is more effective than TAU in improving outcomes in personality disorder. Further studies are required to confirm this conclusion.

Is delusional ideation a critical link in the nexus between personality disorder and violent offending?

Evidence suggests that consideration of personality disorder (PD) severity, incorporating both externalising and internalising features of PD, might help to clarify the PD – violence relationship; moreover, that separate developmental pathways might link externalising and internalising personality pathology with criminal violence. This study of 96 forensic patients with confirmed PD and a history of violent offending addressed the question of whether delusional ideation, measured by the Peters Delusions Inventory, might play a significant role in the link between severe PD and criminal violence. Severe PD, defined by summing scores across DSM-IV PD criteria, was significantly associated with delusional thinking, with violence, and with high levels of both externalising and internalising personality features. Delusional thinking was associated with violence via internalising but not externalising PD features, suggesting that the link between severe PD and violence may be partly mediated by delusional thinking.

A dimensional approach to assessing personality functioning: examining personality trait domains utilizing DSM-IV personality disorder criteria

BackgroundThis study compared a dimensional, trait domain approach to characterizing personality pathology with the traditional polythetic approach with respect to their associations with interpersonal functioning and personality traits from the five factor model. MethodsPsychiatric inpatients (N=1476) were administered the Structured Clinical Interview for DSM-IV Axis II personality disorders. Dimensional representations of trait domains were derived from reorganizing DSM-IV criteria into personality trait domains from DSM-5 Alternative Model. Dimensional scores and personality disorder (PD) total criterion scores served as independent variables in predicting interpersonal profile clusters, as well as extraversion, agreeableness conscientiousness, neuroticism and openness from the five factor model traits. ResultsTrait domain scores and PD criteria totals were significantly correlated with submissive interpersonal style yet none proved significant in regression analyses. Avoidant and borderline PD total criteria were negatively associated with a normative interpersonal style. Combined trait domain of detachment and avoidant PD total criteria predicted a hostile/withdrawn interpersonal style. The trait domain of detachment was negatively associated with five factor traits of extroversion, whereas borderline PD total criteria were negatively associated with conscientiousness. Avoidant and borderline PD total criteria were positively associated with neuroticism. ConclusionsThe cross-cutting dimensional approach provided useful information in predicting a hostile/withdrawn interpersonal style as well as extroversion. Importantly, PD criterion scores and dimensional trait scores combined to predict this interpersonal style providing support to the alternative model of personality diagnosis in DSM-5. Clinicians are encouraged to assess dimensions of personality traits as these are related to interpersonal problems frequently encountered in psychiatric settings. While potentially useful, the dimensional approach articulated here did not yield substantial prediction of behavior.

Personality disorders are the vanguard of the post-DSM-5.0 era.

The process of constructing the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013) has concluded, with the manual published in May 2013. In this article, I review the evolution of personality disorders (PDs) in DSM-5 from my perspective as a participating workgroup member, and as an observer of the DSM-5 construction process. I emphasize well-documented shortcomings of the fourth edition of the DSM (DSM-IV; American Psychiatric Association, 1994), the diversity of potential changes to PD conceptualization and diagnosis that were proposed during the construction of DSM-5, and the final outcome, which consists of reproducing DSM-IV PD criteria in Section II of DSM-5 (diagnostic criteria and codes), while also printing a complete parallel PD system in Section III (emerging measures and models), with the idea of moving elements of the Section III material to Section II as DSM evolves (e.g., in DSM-5.1). Perhaps the PD field is too fractious to arrive at a consensus approach at this juncture, but, in addition, the current situation shows how the PD field is arguably the most forward-thinking area in contemporary psychopathology. This is because many PD scholars do not accept the inadequate polythetic-categorical approach to psychopathology classification of DSM-IV (which, owing to conservative political forces, also frames Section II of DSM-5). PD research is therefore at the vanguard in conceptualizing, studying, and treating psychopathology because it is not slavishly tethered to the DSM, and its approach to defining mental disorder through political processes.

Structure of the DSM-IV Personality disorders as revealed in clinician ratings

The revisions proposed for the DSM-5 would greatly alter how personality pathology is conceptualized, assessed, and diagnosed. One aspect of the proposed changes, elimination of four current personality disorders, has raised considerable controversy. The present study attempts to inform this debate by exploring clinicians’ views of the structure of Personality Disorders using the current diagnostic system, the DSM-IV. An exploratory factor analysis was conducted on the DSM-IV Personality Disorder criteria using clinician ratings for 280 patients. The factor analysis revealed eight clear and meaningful factors. The eight factors contained all six personality disorders proposed for retention in DSM-5 but also contained clear representations of two disorders (Paranoid and Schizoid) identified for removal from the system. These conditions appear to have clinical utility and their removal may have unintended negative consequences in clinical practice. Dependent and Avoidant criteria also merged to form a new construct with interesting clinical implications. These findings provide new insights into the complex typologies clinicians employ when applying the DSM-IV system to personality disordered patients. Lastly we argue that successful refinement of clinically significant constructs, like diagnostic systems, requires a balanced appraisal of evidence for clinical utility as well as external and internal validity.

The neuroendocrinology of childhood trauma in personality disorder

Childhood trauma has been associated with elevated central corticotropin releasing hormone (CRH) drive in adults meeting general DSM-IV criteria for personality disorder. It is not clear how this may be related to pituitary or adrenal responsiveness in personality disorder. It was hypothesized that high levels of childhood trauma would be associated with blunted cortisol and adrenocorticotropin releasing hormone (ACTH) response to the combined dexamethasone(DEX)/CRH test in adults meeting general DSM-IV criteria for personality disorder. 24 healthy, medication free adults with personality disorder (N=16) and a group of healthy controls (N=8) underwent semi-structured diagnostic interviews and completed the Childhood Trauma Questionnaire (CTQ). Across two separate study sessions separated by at least a week, cerebrospinal fluid (CSF) was sampled by lumbar puncture for measurement of CRH concentration (N=17), and peripheral blood cortisol and ACTH levels were measured after challenge with DEX/CRH (N=24). As hypothesized, high CTQ score was associated with a blunted cortisol and ACTH response to DEX/CRH challenge. Indices of cortisol and ACTH response (peak level and area under the curve (AUC)) to DEX/CRH were in turn significantly negatively correlated with CSF CRH concentration. Childhood trauma in adults with personality disorder is associated with blunted cortisol and ACTH secretion following DEX/CRH challenge. These effects are independent of depression or posttraumatic stress disorder. Previous work would suggest that blunted pituitary-adrenal response is related to elevated central CRH drive. Corroborating this, CSF CRH levels were significantly and negatively correlated with peak level and AUC of both cortisol and ACTH.

P02-186 - Prevalence of violent committed acts by inpatients in forensic setting department of psychiatry -in kosova

The aimIn this study we evaluated the prevalence of committed acts in the group of male inpatients in forensic setting with major mental disorder and past history of aggressive behavior in community.MethodologyIn the study we included 80 male inpatients, 41 of them have meet DSM-IV criteria for Personality Disorder, 28 were psychotic, 11 were Drug/alcohol abusers. Past aggressive history was collected from patient interviews and reviews of clinicalforensic records and collateral source of documents.ResultsThe inpatients were adults with mean age 35,22±10,50 in Schizophrenia spectrum disorders group and the mean duration of the illness was 11,7±9,48, Personality disorders group with mean age 31,35±9,85 and mean duration of illness 10,70±8,34, Drug/alcohol abusers with mean age 19,1±8,6 and mean duration of illness 4,5±2,6.Personality disorder and Drug/alcohol abuser group of inpatients offenders were more prevalent on homicide acts 40%, and threatening 35%, while Schizophrenia spectrum disorder inpatients were more prevalent in domestic violence 49,2%, threatening acts committing with 33,3% and homicide prevalence 7,9%.ConclusionThe studies until now showed that the prevalence of Schizophrenia in the homicide offenders is around 6%. Despite this, the prevalence of Personality disorder or of Drug/alcohol abuse is higher: 10% to 38% respectively. Our results showed the same results with prevalence of Schizophrenia spectrum disorder in homicide with 7,9%, and respectively Personality disorder with homicide prevalence 40%.

The Presentation of Narcissistic Personality Disorder in an Octogenarian: Converging Evidence from Multiple Sources

Little is known about personality disorders (PDs) in later life. One reason for this dearth of knowledge is that many investigators believe that PDs soften with age. Recent anecdotal and empirical evidence, however, suggests that PDs are still very relevant in later life and may actually have unique presentations and consequences. The DSM-IV PD criteria seem to overlook these possibilities, perhaps because the personalities of older adults were not sufficiently understood when these criteria were written. But without age-appropriate criteria, clinicians and investigators who work with older adults may be unable to measure PDs adequately in their clients and research participants. A starting point for better understanding these disorders in older adults is the presentation of rich, empirical, clinical descriptions of symptoms and related behaviors using data from multiple instruments and sources. To this end, we describe in depth a case of narcissistic PD (NPD) in a woman in her mid 80s. This case study reveals that NPD is indeed relevant in the context of later life and impairs functioning in significant ways.

Prävalenz und Familiarität von Persönlichkeitsstörungen in Deutschland: Ergebnisse der Greifswalder Familienstudie

There are only few data about the prevalence and familiarity of personality disorders (PD) in population based samples in Germany. Moreover, nearly no information exists for the prevalence of PDs among young adults. Thus, in the current study we examined the prevalence, familiarity and psychopathology of PDs, whereby middle-aged adults (about 45 years old) as well as the adult children of these persons (about 20 years old) were examined. Participants were interviewed with the Structured Clinical Interview for Personality Disorders (SCID-II) which is based on the DSM-IV criteria for PDs and with the SCL-90. The sample consisted of 411 parents and their adolescent children (n=334). The prevalence for PDs was 11.2% in the parent sample and 14.7% in the adolescent sample. Cluster-B personality disorders (Cluster-B-PDs) were more often diagnosed in the adolescent sample, in particular. Moreover, we did find an elevated risk for children of parents with a PD than for children of parents without a PD to develop a PD where the former group also displayed elevated values with regard to their psychopathology. This study underlines the importance of PDs in community-based samples. The implications of our findings for treatment and classification of PDs are discussed.

Personality problems are considerably associated with somatic morbidity and health care utilisation

Purpose To explore the associations between the presence of personality problems and somatic morbidity and health care utilisation. Methods The Iowa Personality Disorder Screen was administered in order to identify persons with personality problems in a Norwegian population survey (the Oslo Health Study – HUBRO). Cases consisted of 369 individuals, 30, 40 and 45 years of age with personality problems matched on age and gender with five controls each. Data on somatic morbidity and health care utilisation were collected by questionnaires. Results The cases more frequently reported persistent muscular pain, asthma, fibromyalgia and alcohol problems than the controls. They also more often used nonprescribed analgesics and antidepressants. The cases more frequently had consulted a general practitioner (GP) in the last 12 months, less frequently got referral to somatic specialist care and were less satisfied with their last visit to a GP. Conclusion In this population based study, personality problems in young adults based on DSM-IV personality disorder criteria were associated with increased occurrence of somatic morbidity and primary health care utilisation. The relevance for GP to take personality problems into account during consultations is underlined and a method for doing so is suggested.

An item response theory analysis of DSM-IV personality disorder criteria across younger and older age groups.

Many of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV; American Psychiatric Association, 1994) personality disorder (PD) diagnostic criteria focus on a younger social and occupational context. The absence of age-appropriate criteria for older adults forces researchers and clinicians to draw conclusions based on existing criteria, which are likely inadequate. To explore which DSM-IV PD criteria contain age group measurement bias, the authors report 2 analyses of data on nearly 37,000 participants, ages 18-98 years, taken from a public data set that includes 7 of the 10 PDs (antisocial, avoidant, dependent, histrionic, obsessive-compulsive, paranoid, and schizoid). The 1st analysis revealed that older age groups tend to endorse fewer PD criteria than younger age groups. The 2nd analysis revealed that 29% of the criteria contain measurement bias. Although the latent variable structure for each PD was quite similar across younger and older age groups, some individual criteria were differentially endorsed by younger and older adults with equivalent PD pathology. The presence of measurement bias for these criteria raises questions concerning the assessment of PDs in older adults and the interpretation of existing data.

Adverse Outcomes Associated With Personality Disorder Not Otherwise Specified in a Community Sample

The authors investigated 1) whether adolescents and adults in the community diagnosed with personality disorder not otherwise specified are at elevated risk for adverse outcomes, and 2) whether this elevation in risk is comparable with that associated with the DSM-IV cluster A, B, and C personality disorders. A community-based sample of 693 mothers and their offspring were interviewed during the offspring's childhood, adolescence, and early adulthood. Offspring psychopathology, aggressive behavior, educational and interpersonal difficulties, and suicidal behavior were assessed. Individuals who met DSM-IV criteria for personality disorder not otherwise specified were significantly more likely than those without personality disorders to have concurrent axis I disorders and behavioral, educational, or interpersonal problems during adolescence and early adulthood. In addition, adolescents with personality disorder not otherwise specified were at significantly elevated risk for subsequent educational failure, numerous interpersonal difficulties, psychiatric disorders, and serious acts of physical aggression by early adulthood. Adolescents with personality disorder not otherwise specified were as likely to have these adverse outcomes as those with cluster A, B, or C personality disorders or those with axis I disorders. Adolescents and young adults in the general population diagnosed with personality disorder not otherwise specified may be as likely as those with DSM-IV cluster A, B, or C personality disorders to have axis I psychopathology and to have behavioral, educational, or interpersonal problems that are not attributable to co-occurring psychiatric disorders. Individuals with personality disorder not otherwise specified and individuals with DSM-IV cluster A, B, or C personality disorders are likely to be at substantially elevated risk for a wide range of adverse outcomes.

Association of C-reactive protein elevation with trait aggression and hostility in personality disordered subjects: A pilot study

Objective The presence of personality traits of aggression and hostility, in generally healthy human subjects, has been shown to be associated with elevations of C-reactive protein (pCRP), which, in turn, has also been shown to be associated with an increased risk of cardiac disease. In this pilot study, the author tests the hypothesis that pCRP elevations are associated with the traits of aggression and hostility in personality disordered subjects, a group at high risk for the presence of aggression and hostility. Method Participants were 99 medically healthy subjects meeting DSM-IV criteria for personality disorder for which both pCRP levels and Buss–Durkee Hostility Inventory (BDHI) Aggression and Hostility data were available. Results Subjects with pCRP levels ⩾1.0 mg/L or higher were found to have significantly higher BDHI Aggression and BDHI Hostility scores than subjects with pCRP levels <1.0 mg/L. Addition of a number of control variables reduced, but did not generally eliminate, differences in the BDHI scores. In contrast, measures of general dimensions of personality did not differ as a function of pCRP Status. Conclusions The association of elevations in pCRP level in medically healthy personality disordered subjects with higher scores of trait aggression and hostility suggests the presence of chronic inflammation in highly aggressive/hostile personality disordered subjects similar to that observed in otherwise healthy individuals at risk for coronary artery disease. Further studies are warranted to determine the clinical correlates of this finding.

Childhood Trauma and Personality Disorder: Positive Correlation With Adult CSF Corticotropin-Releasing Factor Concentrations

To test the hypothesis that early life trauma results in adult stress hormone alterations in individuals with personality disorders, the authors examined the relationship between history of childhood adversity and lumbar CSF corticotropin-releasing factor (CRF). Participants were 20 otherwise healthy men who met DSM-IV criteria for personality disorders. CSF CRF was obtained by lumbar puncture, and childhood adversity was measured by the Childhood Trauma Questionnaire. Correlations were obtained between CSF CRF and the total score on the Childhood Trauma Questionnaire as well as scores on its four subscales. CSF CRF concentrations were positively correlated with the total score on the Childhood Trauma Questionnaire. Analysis of the subscales revealed that CSF CRF was correlated with emotional neglect. Correlations between CSF CRF level and physical and emotional abuse and with physical neglect were not statistically significant. Consistent with the hypothesis that the severity of early life stress is correlated with stress hormone abnormalities in adulthood, Childhood Trauma Questionnaire total scores and emotional neglect scores were significantly correlated with CSF CRF levels in individuals with personality disorders.

Perceived dysfunction of male-typed and female-typed DSM-IV personality disorder criteria.

To determine whether female-typed personality disorders are associated with a different pattern of dysfunction than male-typed disorders, lay judges (N = 216) estimated the amount of social impairment, occupational impairment, and personal distress related to symptoms of personality disorders. Results for both the subset of six disorders originally rated by clinician judges in the research of Funtowicz and Widiger (1999) and for a larger set of nine disorders revealed a pattern originally reported by Funtowicz and Widiger where female-typed disorders were associated with relatively higher ratings of personal distress, whereas male-typed disorders were associated with relatively higher ratings of social (and sometimes occupational) impairment. Findings are discussed with respect to the emphasis of different forms of dysfunction for male- and female-typed disorders, lay versus clinician judgments, and directions for future research.

Effects of Sex and Sex Roles on the Perceived Maladaptiveness of DSM-IV Personality Disorder Symptoms

This study investigated the influence of sex on the perceived maladaptiveness of DSM-IV personality disorder criteria based on previous findings that inconsistency of symptoms with sex roles affects the perception of personality disorder symptoms. The effects of rater characteristics (i.e., sex, sex role) were also examined. A total of 161 undergraduates (65 men, 96 women) rated the diagnostic criteria according to how maladaptive they were for males (male condition), females (female condition), or without regard to sex (neutral condition that served as a baseline) using a 7-point scale. Participants' sex role was determined using the Bem Sex Role (1981a) Inventory. Dependent and depressive personality disorder criteria (trend for borderline) were rated more maladaptive for females than males, whereas obsessive-compulsive personality disorder criteria were rated more maladaptive for males than females. Participant sex and sex role had little or no significant effects on the ratings. Results are compared with those of previous research. Methodological issues and implications for the diagnosis of personality disorders are discussed.
