Interpersonal Problems Associated With Passive-Aggressive Personality Disorder.

With a controversial history, passive-aggressive personality disorder (PAPD) was eventually removed from the latest edition of the Diagnostic and Statistical Manual for Mental Disorders. Despite its demise from diagnostic nomenclature, clinicians continue to regard it as a clinically relevant construct, and some researchers argue for its resurrection. Toward this end, it is important to empirically demonstrate the relevance of the passive-aggressive personality construct, including demonstrating its association with impaired functioning. Consistent with contemporary emphasis on interpersonal functioning in personality pathology, the current study aims to explore interpersonal problems that are associated with PAPD in a large clinical sample. Before beginning treatment, 240 patients completed assessments of personality psychopathology and interpersonal functioning. Results showed that higher levels of PAPD were significantly associated with greater level of interpersonal distress, especially regarding interpersonal problems of a vindictive nature. The findings are consistent with clinical descriptions of the core conflictual relational issues of patients with PAPD and lend some support to further considering PAPD as a valid diagnostic construct.

A comparison of passive-aggressive and negativistic personality disorders.

Passive-aggressive personality disorder (PAPD) has historically played an important role in clinical theorizing and was diagnosable prior to the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994), in which the construct was relabeled negativistic (NEGPD), expanded to include negative affective symptoms, and appendicized. In this study we tested the hypothesis that the expansion of PAPD to include content related to negative moods and nonspecific personality pathology compromised its discriminant validity. In an undergraduate sample (N = 1,215), a self-report measure of PAPD was only moderately related to NEGPD and showed less diagnostic overlap with other personality disorders than NEGPD. Furthermore, a conjoint factor analysis yielded a strong first factor (moodiness) that appeared less specific to passive-aggressive behavior than 3 other factors (irresponsibility, inadequacy, and contempt). We conclude that future research on this potentially important clinical construct should focus on core passive-aggressive features and abandon the negativistic content that has been added to it in successive editions of the DSM.

The construct validity of passive-aggressive personality disorder.

Although Passive Aggressive personality disorder (PAPD) plays an important role in many theories of personality pathology, it was consigned to the appendix of the fourth edition of the DSM. The scientific basis of this decision has been questioned, but several controversies persist regarding PAPD, including its structure, content validity, overlap with other PDs, and relations to validating variables such as personality traits, childhood experiences, and clinically relevant correlates. This study examined these facets of PAPD's construct validity in a large clinical sample. Results suggest that the construct is unidimensional, internally consistent, and reasonably stable. Furthermore, PAPD appears systematically related to borderline and narcissistic personality disorders, sets of personality traits, and childhood experiences consistent with several theoretical formulations, dysfunction, substance abuse disorders, and history of hospitalizations. Overall, results support the construct validity of PAPD.

Passive-aggressive (negativistic) personality disorder: a population-based twin study.

The objective of this study was to investigate the familial aggregation of passive aggressive personality disorder (PAPD), and explore issues regarding PAPD raised by the DSM-IV Personality Disorder Work Group. Two thousand seven hundred and ninety-four Norwegian twins from the population-based Norwegian Institute of Public Health Twin Panel were interviewed with the Structured Interview for DSM-IV Personality (SIDP-IV). Because of the rarity of the twins meeting full diagnostic criteria for PAPD a dimensional representation of the disorder was used for the analyses. Overlap with other axis II disorders was assessed by polychoric correlations, while familial aggregation was explored by structural equation twin models. Overlap was highest with paranoid (r = 0.52) and borderline personality disorder (r = 0.53), and lowest with schizoid (r = 0.26). Significant familial aggregation was found for PAPD. The twin correlations and parameter estimates in the full model indicated genetic and shared environmental effects for females, and only shared environmental effects for males, but the prevalence of endorsed PAPD criteria in this community sample was too low to permit us to conclude with confidence regarding the relative influence of genetic and shared environmental factors on the familial aggregation of PAPD.

The validity of DSM-IV passive-aggressive (negativistic) personality disorder.

Passive-Aggressive (Negativistic) Personality Disorder (NEGPD), listed in Appendix B of the DSM-IV, is not an officially recognized personality disorder. Its future as a discrete disorder is uncertain (Widiger, 2003). Yet, NEGPD occupies a role in some theoretical formulations of personality pathology (Millon & Davis, 1996), and many clinicians believe that passive-aggressive traits are not adequately represented by other PDs (Westen, 1997). In this study, 1158 psychiatric outpatients were assessed for Axis I and Axis II disorders. Thirty-five (3.02%) met criteria for NEGPD. Participants with NEGPD did not differ significantly from those without NEGPD on demographic variables. The internal consistency of the DSM-IV's seven NEGPD items was 0.50. Corrected item- total correlations for the 7 criteria averaged 0.27. Participants with NEGPD had higher rates of lifetime anxiety disorders, and almost 90% had an additional PD. An exploratory factor analysis suggested a two- factor solution that accounted for 43.4% of the variance. The first factor reflected the belief that life is unfair, while the second factor seemed to reflect modes of anger expression. A confirmatory factor analysis showed that the two-factor model fit the data better than a unidimensional model. We discuss implications of these results for the future of the NEGPD diagnosis.

Accurate phenotyping: Reconciling approaches through Bayesian model averaging.

Genetic research into complex diseases is frequently hindered by a lack of clear biomarkers for phenotype ascertainment. Phenotypes for such diseases are often identified on the basis of clinically defined criteria; however such criteria may not be suitable for understanding the genetic composition of the diseases. Various statistical approaches have been proposed for phenotype definition; however our previous studies have shown that differences in phenotypes estimated using different approaches have substantial impact on subsequent analyses. Instead of obtaining results based upon a single model, we propose a new method, using Bayesian model averaging to overcome problems associated with phenotype definition. Although Bayesian model averaging has been used in other fields of research, this is the first study that uses Bayesian model averaging to reconcile phenotypes obtained using multiple models. We illustrate the new method by applying it to simulated genetic and phenotypic data for Kofendred personality disorder-an imaginary disease with several sub-types. Two separate statistical methods were used to identify clusters of individuals with distinct phenotypes: latent class analysis and grade of membership. Bayesian model averaging was then used to combine the two clusterings for the purpose of subsequent linkage analyses. We found that causative genetic loci for the disease produced higher LOD scores using model averaging than under either individual model separately. We attribute this improvement to consolidation of the cores of phenotype clusters identified using each individual method.

Is the appendix a useful appendage? An empirical examination of depressive, passive-aggressive (negativistic), sadistic, and self-defeating personality disorders.

Decisions about whether to include depressive, passive-aggressive, sadistic, and self-defeating disorders in Axis II have been made difficult by a relative dearth of data. We report the results of a study identifying potential defining features of these diagnoses and assessing their distinctiveness from other Axis II personality disorders (PDs). A national sample of experienced psychiatrists and psychologists used the SWAP-200 to describe a patient with a current axis II disorder or an appendix or deleted PD from DSM-II-R. We examined clinicians' descriptions of patients to identify their most characteristic features, and then applied an empirical clustering procedure, Q-factor analysis, to see whether versions of these disorders would emerge empirically. As currently conceptualized, only passive-aggressive PD was distinct from other PDs. When the data were subjected to Q-factor analysis, the first and largest grouping was a dysphoric (depressive) PD. A hostile-negativistic subcategory emerged that resembled passive-aggressive PD, along with a revised dependent diagnosis that included many self-defeating/masochistic features. The results suggest that a depressive or dysphoric personality may represent an internalizing spectrum of personality pathology, and that a hostile-negativistic PD may be distinct from the disorders in the text of DSM-IV. Sadistic and self-defeating PD do not appear to represent distinct disorders, although they include personality traits (sadism and revictimization) associated with distinct developmental histories.

A psychometric typology of U.K. domestic violence offenders.

A number of studies have described subtypes of domestically violent men, and the heterogeneity of domestically violent men is well established. The aim of the current study was to investigate the distribution of subtypes using psychometric measures in convicted domestically violent offenders in England. Four subtypes of offenders were identified: low pathology, borderline, narcissistic, and antisocial. These subtypes were broadly comparable with the family-only, dysphoric/borderline, and generally violent/antisocial types proposed by Holtzworth-Munroe and Stuart. The majority of the sample (60%) best fit the generally violent/antisocial profile. However, the reliance on psychometric measurement and lack of corroborative evidence from partners means that further research is necessary to test these findings.

DSM-III personality disorder diagnoses in a nonpatient sample. Demographic correlates and comorbidity.

Seven hundred ninety-seven first-degree relatives of normal controls and patients with a variety of psychiatric disorders were interviewed with the Diagnostic Interview Schedule and the Structured Interview for DSM-III Personality Disorders. Slightly more than one sixth of the sample received a personality disorder (PD) diagnosis, and of those with a PD, almost one fourth had more than one. The most prevalent diagnoses were mixed, passive-aggressive, antisocial, histrionic, and schizotypal PD. The demographic correlates and frequency of Axis I disorders in individuals with each specific PD were examined, and all but histrionic and passive-aggressive PDs had distinctive profiles.

Borderline diagnoses.

The author describes the development of the borderline concept and the apparent inaccuracy of the original hypothetical framework. The signs and symptoms used to describe a "borderline syndrome" are often shared with other psychiatric illnesses. The author recommends that clinicians consider patients with only those features as "undiagnosed" until further research determines whether a distinct syndrome exists.

Frequency of personality disorders in two age cohorts of psychiatric inpatients.

OBJECTIVE: The authors examined the frequency of DSM-III-R personality disorders in adolescent and young adult psychiatric inpatients. METHOD: Structured diagnostic interviews were reliably performed with a series of 255 consecutively admitted inpatients (138 adolescents and 117 young adults). RESULTS: Most personality disorders were diagnosed in similar frequencies in the two study groups. Passive-aggressive personality disorder was diagnosed with lower frequency and dependent personality disorder with higher frequency in the young adult than in the adolescent group. CONCLUSIONS: The isomorphism of relative frequencies among psychiatric inpatients suggests that what is seen in adolescents are valid forms of most adult personality disorders.

A psychometric study of DSM-IV passive-aggressive (negativistic) personality disorder criteria.

The passive-aggressive (negativistic) personality disorder (PAPD) is one of the most controversial personality disorders. In order to assess DSM-IV PAPD psychometric properties and comorbidity pattern in a mixed psychiatric sample, 379 consecutively admitted in- and outpatients were administered SCID-II, Version 2.0. Confirmatory factor analysis showed that DSM-IV PAPD is a unidimensional construct with adequate internal consistency (K-R 20 = .85). A strong, specific association (odds ratio = 10.38, 95% CI = 4.83-22.30) was observed between DSM-IV PAPD and narcissistic personality disorder (NPD). Confirmatory factor analysis showed that DSM-IV PAPD should be considered as a subtype of a broader narcissistic disorder.

Children's understanding of their emotionally disturbed peers. I. The concept of emotional disturbance.

Study of the interpersonal relations of emotionally disturbed children has focused largely on relationships within the family. Theories of childhood psychopathology focus almost exclusively on the parent-child triad as the etiological core of childhood emotional disturbance (Frank, 1965). Far less attention has been paid to the role of extra-familial attitudes and relationships in childhood psychopathology. In a general way, the increasing importance of the peer group during childhood has been recognized, but researchers have hardly begun to consider whether and how the manifold aspects of relationships between the emotionally disturbed and their normal peers might bear on the course of the disturbance or its refractoriness to treatment (e.g., Solomon and Wahler, 1973). Nor have they considered peer group influences on the development of the emotionally disturbed child's perception of the world and his place within it. Despite increasing recognition of the early importance of peer relations, virtually no systematic information exists on the ways in which normal children view their emotionally disturbed peers. Our purpose in this paper is to report the first of several analyses of data from an initial investigation of children's understanding of their emotionally disturbed peers. Specifically, we wish to examine whether there is evidence that normal children do, in fact, perceive as emotionally disturbed the symptomatic and distressing behavior of peers that mental health professionals would recognize as indicative of psychopathology. Further, we wish to study these issues with respect to grade and sex differences.

Passive-aggressive personality disorder: the demise of a syndrome.

This article presents an explanation and critique of the rationale for dropping passive-aggressive personality disorder (PAPD) from DSM-IV. The clinical and research literature on PAPD is reviewed along with the historical changes in definition, diagnostic criteria, and usage. PAPD can be reliably diagnosed, is fairly prevalent, and has good internal consistency. Because PAPD is no less valid than other personality disorders, and describes clinical phenomena that are unique among personality disorders, we recommend the reinstatement of PAPD in the official diagnostic nomenclature.

Empirical classification of emotional adjustment reactions.

The validity of a diagnostic classification scheme for the emotional adjustment reactions of children is tested, and empirical findings are offered in support of a descriptive approach to classification. Results validate clinical observations of four types of children commonly seen for emotional adjustment reactions. Further research is proposed to develop instruments for personality assessment that would be sensitive to these categories.

A large sample empirical typology of male spouse abusers and its relationship to dimensions of abuse.

A number of studies have described typologies of domestically violent men. Holtzworth-Munroe and Stuart (1994) recently proposed a theoretical model for predicting violence severity and generality from personality "type." The present study, using data from 833 identified abusive men, tested the model. Personality types were determined from cluster analysis of data from the Millon Clinical Multiaxial Inventory, and resulted in a three-cluster solution consistent with the Holtzworth-Munroe and Stuart model. The three main clusters included nonpathological, antisocial, and passive aggressive-dependent groups. Three other, smaller types were also identified. Multivariate and chi-square analyses comparing the main clusters on other variables generally supported the Holtzworth-Munroe and Stuart model. Nonpathological men had the lowest maximum violence and frequency. They restricted their violence primarily to intimate relationships and had the fewest police contacts. Antisocial and passive aggressive-dependent men did not differ in maximum violence, but antisocial men were the most generally violent and had the most police contacts. Passive aggressive-dependent men had the highest frequency of violence. Clinical, theoretical and methodological implications are discussed.

Diagnostic validity of the passive-aggressive personality disorder: suggestions for reform.

Numerous problems have plagued the diagnosis of the passive-aggressive (P-A) personality disorder. Based on criteria established to evaluate the functional utility of diagnostic categories, the P-A personality disorder does not appear to be an adequate psychiatric diagnosis. However, the concept of passive-aggressiveness may be retained as a useful psychiatric construct when viewed from a dimensional rather than a categorical perspective. A model is presented that describes passive-aggressiveness as consisting of five interrelated psychological factors: rigidity, resentment, resistance, reactance, and reversed reinforcement. This interactive model provides a more detailed and richer description of the P-A style than what is captured in the current diagnostic nomenclature. It is hoped that the model's characterization of P-A in concrete and testable terms will facilitate research into the utility of the passive-aggressiveness construct.

A randomized controlled trial of sequentially bilateral prefrontal cortex repetitive transcranial magnetic stimulation in the treatment of negative symptoms in schizophrenia.

BACKGROUND: Repetitive transcranial magnetic stimulation (rTMS) has been investigated for its treatment efficacy for the negative symptoms of schizophrenia. Previous studies have targeted the dorsolateral prefrontal cortex (DLPFC), which is associated with the pathophysiology of this disorder. Several rTMS parameters have been explored in the treatment of negative symptoms and include stimulating the left and bilateral DLPFC at several different frequencies and number of sessions. Results of such studies have been inconsistent, while high-frequency rTMS has shown greatest promise. OBJECTIVE/HYPOTHESIS: The objective of this study was to evaluate the efficacy of bilateral high-frequency rTMS in the treatment of negative symptoms in schizophrenia. It was hypothesized rTMS would alleviate negative symptoms in schizophrenia. METHODS: Twenty-five patients were enrolled in this double-blind placebo-controlled randomized trial. Bilateral 20 Hz rTMS was MRI-targeted to the DLPFC at 90% RMT administered daily for 4 weeks for a total of 20 treatments. Negative symptoms were assessed with the Scale for the Assessment of Negative Symptoms (SANS), the Positive and Negative symptom scale (PANSS), and controlling for depression as measured with the Calgary Depression Scale (CDS) at baseline, 1, 2, 3, 4, and 2 weeks after the treatment course. RESULTS: No significant group or time differences were found on negative symptoms or depressive symptoms after rTMS. Bilateral high-frequency rTMS did not alleviate negative symptoms in patients with schizophrenia. CONCLUSIONS: These findings indicate that such symptoms are unresponsive to rTMS treatment or that more optimized parameters are needed to achieve improved therapeutic efficacy.
