Avoidant Personality Disorder, Traits, And Type, Charles A. Sanislow, Katelin Da Cruz, May O. Gianoli, Elizabeth M. Reagan

Charles A. Sanislow, Ph.D.

In this chapter, the evolution of the avoidant personality disorder (AVPD) diagnosis, its current status, and future possibilities are reviewed. AVPD is a chronic and enduring condition involving a poor sense of self and anxiety in social situations, and it is marked by fears of rejection and a distant interpersonal stance. AVPD may be conceptualized at the severe end of a continuum of social anxiety. In the extreme, traits, mechanisms, and symptoms become integral to chronic dysfunction in personality and interpersonal style. While AVPD is a valid diagnostic construct, the optimal organization of AVPD criteria for the diagnosis, and the …

Long Term Predictive Validity Of Diagnostic Models For Personality Disorder: Integrating Trait And Disorder Concepts, Leslie C. Morey, Christopher J. Hopwood, John C. Markowitz, John G. Gunderson, Carlos M. Grilo, Thomas H. Mcglashan, M. Tracie Shea, Shirley Yen, Charles A. Sanislow, Andrew E. Skodol

Charles A. Sanislow, Ph.D.

Background. Several conceptual models have been considered for the assessment of personality pathology in DSM-5. This study sought to extend our previous findings to compare the long-term predictive validity of three such models: the Five-Factor Model (FFM), the Schedule for Nonadaptive and Adaptive Personality (SNAP), and DSM-IV personality disorders (PDs).

Method. An inception cohort from the Collaborative Longitudinal Personality Disorder Study (CLPS) was followed for 10 years. Baseline data were used to predict long-term outcomes, including functioning, Axis I psychopathology, and medication use.

Results. Each model was significantly valid, predicting a host of important clinical outcomes. Lower-order elements of the …

Long-Term Outcomes In Borderline Psychopathology: Old Assumptions, Current Findings, And New Directions, Charles A. Sanislow, Katherine L. Marcus, Elizabeth M. Reagan

Charles A. Sanislow, Ph.D.

Borderline personality disorder (BPD) and historical variants of the diagnosis were long held to represent an intractable syndrome of psychopathology consisting of interpersonal, intrapsychic, and affective disturbances. For years, patients labeled “borderline” were regarded pejoratively due at least in part to the lack of effective treatments. Prospective data from recent naturalistic follow-along studies along with the development of treatments with empirically demonstrated efficacy have changed how BPD is viewed. It is now less common to hide the diagnosis from the patient, and BPD has become a useful label to guide the treatment process and help the patient make sense of …

Comparing The Temporal Stability Of Self-Report And Interview Assessed Personality Disorder, Douglas B. Samuel, Christopher J. Hopwood, Emily B. Ansell, Leslie C. Morey, Charles A. Sanislow, John C. Markowitz, Shirley Yen, M. Tracie Shea, Andrew E. Skodol, Carlos M. Grilo

Charles A. Sanislow, Ph.D.

Findings from several large-scale, longitudinal studies over the last decade have challenged the long-held assumption that personality disorders (PDs) are stable and enduring. However, the findings, including those from the Collaborative Longitudinal Personality Disorders Study (CLPS; Gunderson et al., 2000), rely primarily on results from semistructured interviews. As a result, less is known about the stability of PD scores from self-report questionnaires, which differ from interviews in important ways (e.g., source of the ratings, item development, and instrument length) that might increase temporal stability. The current study directly compared the stability of the Diagnostic and Statistical Manual of Mental Disorders …

Personality Assessment In Dsm--5: Empirical Support For Rating Severity, Style, And Traits, Christopher J. Hopwood, Johanna C. Malone, Emily B. Ansell, Charles A. Sanislow, Carlos M. Grilo, Thomas H. Mcglashan, Anthony Pinto, John C. Markowitz, M. Tracie Shea, Andrew E. Skodol, John G. Gunderson, Mary C. Zanarini, Leslie C. Morey

Charles A. Sanislow, Ph.D.

Despite a general consensus that dimensional models are superior to the categorical representations of personality disorders in DSM-IV, proposals for how to depict personality pathology dimensions vary substantially. One important question involves how to separate clinical severity from the style of expression through which personality pathology manifests. This study empirically distinguished stylistic elements of personality pathology symptoms from the overall severity of personality disorder in a large, longitudinally assessed clinical sample (N = 605). Data suggest that generalized severity is the most important single predictor of current and prospective dysfunction, but that stylistic elements also indicate specific areas of difficulty. …

Developing Constructs For Psychopathology Research: Research Domain Criteria, Charles A. Sanislow, Daniel S. Pine, Kevin J. Quinn, Michael J. Kozak, Marjorie A. Garvey, Robert K. Heinssen, Philip Sung-En Wang, Bruce N. Cuthbert

Charles A. Sanislow, Ph.D.

There exists a divide between findings from integrative neuroscience and clinical research focused on mechanisms of psychopathology. Specifically, a clear correspondence does not emerge between clusters of complex clinical symptoms and dysregulated neurobiological systems, with many apparent redundancies. For instance, many mental disorders involve multiple disruptions in putative mechanistic factors (e.g., excessive fear, deficient impulse control), and different disrupted mechanisms appear to play major roles in many disorders. The Research Domain Criteria (RDoC) framework is a heuristic to facilitate the incorporation of behavioral neuroscience in the study of psychopathology. Such integration might be achieved by shifting the central research focus …

Personality Traits As Prospective Predictors Of Suicide Attempts, Shirley Yen, M. Tracie Shea, Charles A. Sanislow, Andrew E. Skodol, Carlos M. Grilo, Maria O. Edelen, Robert L. Stout, Leslie C. Morey, Mary C. Zanarini, John C. Markowitz, Thomas H. Mcglashan, Maria T. Daversa, John G. Gunderson

Charles A. Sanislow, Ph.D.

OBJECTIVE: To examine higher order personality factors of negative affectivity (NA) and disinhibition (DIS), as well as lower order facets of impulsivity, as prospective predictors of suicide attempts in a predominantly personality disordered sample.

METHOD: Data were analyzed from 701 participants of the Collaborative Longitudinal Personality Disorders Study with available follow-up data for up to 7 years. Cox proportional hazards regression analyses was used to examine NA and DIS, and facets of impulsivity (e.g. urgency, lack of perseverance, lack of premeditation and sensation seeking), as prospective predictors of suicide attempts.

RESULTS: NA, DIS and all facets of impulsivity except for …

Differential Impairment As An Indicator Of Sex Bias In Dsm-Iv Criteria For Four Personality Disorders., Christina D. Boggs, Leslie C. Morey, Andrew E. Skodol, M. Tracie Shea, Charles A. Sanislow, Carlos M. Grilo, Thomas H. Mcglashan, Mary C. Zanarini, John G. Gunderson

Charles A. Sanislow, Ph.D.

This reprinted article originally appeared in Psychological Assessment, 2005, Vol. 17, (No. 4), 492–496. (The following abstract of the original article appeared in record 2005-16347-014.) The aim of the present study was to investigate the possibility of sex bias in the diagnostic criteria for borderline, schizotypal, avoidant, and obsessive–compulsive personality disorders. A clinical sample of 668 individuals was evaluated for personality disorder criteria using a semistructured interview, and areas of functional impairment were assessed with both self-report and semistructured interview. The authors used a regression model of bias to identify bias as differences in slopes or intercepts between men and …

Ten-Year Stability And Latent Structure Of The Dsm-Iv Schizotypal, Borderline, Avoidant, And Obsessive-Compulsive Personality Disorders, Charles A. Sanislow, Todd D. Little, Carlos M. Grilo, Maria Daversa, John C. Markowitz, Anthony Pinto, M. Tracie Shea, Shirley Yen, Andrew E. Skodol, Leslie C. Morey, John G. Gunderson, Mary C. Zanarini, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

Evaluation of the validity of personality disorder (PD) diagnostic constructs is important for the impending revision of the Diagnostic and Statistical Manual of Mental Disorders. Prior factor analytic studies have tested these constructs in cross-sectional studies, and models have been replicated longitudinally, but no study has tested a constrained longitudinal model. The authors examined 4 PDs in the Collaborative Longitudinal Personality Disorders study (schizotypal, borderline, avoidant, and obsessive-compulsive) over 7 time points (baseline, 6 months, 1 year, 2 years, 4 years, 6 years, and 10 years). Data for 2-, 4-, 6- and 10-year assessments were obtained in semistructured interviews by …

The Construct Validity Of Rule-Breaking And Aggression In An Adult Clinical Sample, Christopher J. Hopwood, S. Alexandra Burt, John C. Markowitz, Shirley Yen, M. Tracie Shea, Charles A. Sanislow, Carlos M. Grilo, Emily B. Ansell, Thomas H. Mcglashan, John G. Gunderson, Mary C. Zanarini, Andrew E. Skodol, Leslie C. Morey

Charles A. Sanislow, Ph.D.

Previous research has demonstrated that aggression (AGG) and non-aggressive rule-breaking (RB) represent elements of antisocial behavior with different etiological mechanisms and associations to personality and psychopathology. However, these constructs have not been investigated in an adult clinical sample. In the current study, interview and self-report derived AGG and RB were associated with personality traits and disorders as well as functioning across several domains, family history, concurrent psychopathology, and prospective behaviors. Both AGG and RB were similarly related to disagreeableness. RB was uniquely related to low conscientiousness, cluster B personality disorders, functioning, problems in childhood, suicide risk, arrests, and substance use …

Can Clinicians Recognize Dsm-Iv Personality Disorders From Five-Factor Model Descriptions Of Patient Cases?, Benjamin M. Rottman, Woo-Kyoung Ahn, Charles A. Sanislow, Nancy S. Kim

Charles A. Sanislow, Ph.D.

Objective: This article examined, using theories from cognitive science, the clinical utility of the Five-Factor Model (FFM) of Personality, an assessment and classification system under consideration for integration into the forthcoming fifth edition of the Diagnostic and Statistical Manual (DSM) of Mental Disorders. Specifically, the authors sought to test whether FFM descriptors are specific enough to allow practicing clinicians to capture core features of personality disorders.

Method: In two studies, a large nationwide sample of clinical psychologists, psychiatrists, and clinical social workers (N = 187 and N = 191) were presented case profiles based on symptom formats from either the …

Improvement In Borderline Personality Disorder In Relationship To Age, M. Tracie Shea, Maria O. Edelen, Shirley Yen, John G. Gunderson, Andrew E. Skodol, Charles A. Sanislow, Carlos M. Grilo, Emily B. Ansell, Maria T. Daversa, Mary C. Zanarini, Thomas H. Mcglashan, Leslie C. Morey

Charles A. Sanislow, Ph.D.

Objective: It is commonly believed that some features of borderline personality disorder (BPD) improve as individuals reach their late 30s and 40s. This study examined age-related change in borderline criteria and functional impairment, testing the hypothesis that older age would be associated with relatively more improvement than younger age.

Method: A total of 216 male and female participants with BPD were followed prospectively with yearly assessments over 6 years.

Results: Participants showed similar rates of improvement in borderline features regardless of age. A significant age by study year interaction showed functioning in older subjects to reverse direction and begin to …

New Onsets Of Substance Use Disorders In Borderline Personality Disorder Over 7 Years Of Follow-Ups: Findings From The Collaborative Longitudinal Personality Disorders Study, Marc Walter, John G. Gunderson, Mary C. Zanarini, Charles A. Sanislow, Carlos M. Grilo, Thomas H. Mcglashan, Leslie C. Morey, Shirley Yen, Robert L. Stout, Andrew E. Skodol

Charles A. Sanislow, Ph.D.

Aims: The purpose of this study was to examine whether patients with borderline personality disorder (BPD) have a higher rate of new onsets of substance use disorders (SUD) than do patients with other personality disorders (OPD).

Design: This study uses data from the Collaborative Longitudinal Personality Disorder Study (CLPS), a prospective naturalistic study with reliable repeated measures over 7 years of follow-up.

Setting: Multiple clinical sites in four northeastern US cities.

Participants: A total of 175 patients with BPD and 396 patients with OPD (mean age 32.5 years) were assessed at baseline and at 6, 12, 24, 36, 48, 60, …

Personality Traits And Mental Health Treatment Utilization, Christopher J. Hopwood, Brian D. Quigley, Carlos M. Grilo, Charles A. Sanislow, Thomas H. Mcglashan, Shirley Yen, M. Tracie Shea, Mary C. Zanarini, John G. Gunderson, Andrew E. Skodol, John C. Markowitz, Leslie C. Morey

Charles A. Sanislow, Ph.D.

Recent theory and research suggest a relation between five-factor model personality traits and mental health treatment utilization, even after controlling for psychiatric disorders and global functioning. The current report further tests this hypothesis in a large clinical sample, using a wider array of treatment modalities than has been previously studied. Overall, results were limited and inconsistent. Although neuroticism was related to utilization across treatment modalities, many of these relationships resulted from its association with psychiatric diagnoses. Other traits showed limited and inconsistent relations to the use of psychosocial and psychiatric treatments.

A Comparison Of Interview And Self-Report Methods For The Assessment Of Borderline Personality Disorder Criteria, Christopher J. Hopwood, Leslie C. Morey, Maria Orlando Edelen, M. Tracie Shea, Carlos M. Grilo, Charles A. Sanislow, Thomas H. Mcglashan, Maria T. Daversa, John G. Gunderson, Mary C. Zanarini, John C. Markowitz, Andrew E. Skodol

Charles A. Sanislow, Ph.D.

Interview methods are widely regarded as the standard for the diagnosis of borderline personality disorder (BPD), whereas self-report methods are considered a time-efficient alternative. However, the relative validity of these methods has not been sufficiently tested. The current study used data from the Collaborative Longitudinal Personality disorder Study to compare diagnostic base rates and the relative validity of interview and self-report methods for assessing functional outcome in BPD. Although self-report yielded higher base rates of criteria endorsement, results did not support the common assumption that diagnostic interviews are more valid than self-reports, but instead indicated the combined use of these …

Ethnicity And Mental Health Treatment Utilization By Patients With Personality Disorders, Donna S. Bender, Andrew E. Skodol, Ingrid R. Dyck, John C. Markowitz, M. Tracie Shea, Shirley Yen, Charles A. Sanislow, Anthony Pinto, Mary C. Zanarini, Thomas H. Mcglashan, John G. Gunderson, Maria T. Daversa, Carlos M. Grilo

Charles A. Sanislow, Ph.D.

The authors examined the relationship between ethnicity and treatment utilization by individuals with personality disorders (PDs). Lifetime and prospectively determined rates and amounts of mental health treatments received were compared in over 500 White, African American, and Hispanic participants with PDs in a naturalistic longitudinal study. Minority, especially Hispanic, participants were significantly less likely than White participants to receive a range of outpatient and inpatient psychosocial treatments and psychotropic medications. This pattern was especially pronounced for minority participants with more severe PDs. A positive support alliance factor significantly predicted the amount of individual psychotherapy used by African American and Hispanic …

Comparison Of Alternative Models For Personality Disorders, Leslie C. Morey, Christopher J. Hopwood, John G. Gunderson, Andrew E. Skodol, M. Tracie Shea, Shirley Yen, Robert L. Stout, Mary C. Zanarini, Carlos M. Grilo, Charles A. Sanislow, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

BACKGROUND: The categorical classification system for personality disorder (PD) has been frequently criticized and several alternative dimensional models have been proposed.

METHOD: Antecedent, concurrent and predictive markers of construct validity were examined for three models of PDs: the Five-Factor Model (FFM), the Schedule for Nonadaptive and Adaptive Personality (SNAP) model and the DSM-IV in the Collaborative Study of Personality Disorders (CLPS) sample.

RESULTS: All models showed substantial validity across a variety of marker variables over time. Dimensional models (including dimensionalized DSM-IV) consistently outperformed the conventional categorical diagnosis in predicting external variables, such as subsequent suicidal gestures and hospitalizations. FFM facets …

Positive Childhood Experiences: Resilience And Recovery From Personality Disorder In Early Adulthood, Andrew E. Skodol, Donna S. Bender, Maria E. Pagano, M. Tracie Shea, Shirley Yen, Charles A. Sanislow, Carlos M. Grilo, Maria T. Daversa, Robert L. Stout, Mary C. Zanarini, Thomas H. Mcglashan, John G. Gunderson

Charles A. Sanislow, Ph.D.

OBJECTIVE: Recent follow-along studies of personality disorders have shown significant improvement in psychopathology over time. The purpose of this study was to prospectively investigate the association between positive childhood experiences related to resiliency and remission from personality disorder.

METHOD: Five hundred twenty patients with DSM-IV-based semistructured interview diagnoses of schizotypal, borderline, avoidant, or obsessive-compulsive personality disorders were evaluated 6 times over 4 years between September 1996 and June 2002. Positive childhood experiences, including achievements, positive interpersonal relationships with others, and caretaker competencies, were measured using the Childhood Experiences Questionnaire-Revised. The effects of positive childhood experiences on clinically significant remission from …

Longitudinal Diagnostic Efficiency Of Dsm-Iv Criteria For Borderline Personality Disorder: A 2-Year Prospective Study, Carlos M. Grilo, Charles A. Sanislow, Andrew E. Skodol, John G. Gunderson, Robert L. Stout, Donna S. Bender, Shirley Yen, M. Tracie Shea, Leslie C. Morey, Mary C. Zanarini, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

OBJECTIVE: To examine the longitudinal diagnostic efficiency of the DSM-IV criteria for borderline personality disorder (BPD). METHODS: At baseline, we used semistructured diagnostic interviews to determine criteria and diagnoses; blinded assessments were performed 24 months later with 550 participants. Diagnostic efficiency indices (specifically, conditional probabilities, total predictive power, and kappa) were calculated for each criterion determined at baseline, with the independent BPD diagnosis at follow-up used as the standard. RESULTS: Longitudinal diagnostic efficiencies for the BPD criteria varied, with the criteria of suicidality or self-injury and unstable relationships demonstrating the most predictive utility. CONCLUSIONS: BPD criteria differ in their predictive …

Natural Course Of Bulimia Nervosa And Of Eating Disorder Not Otherwise Specified: 5-Year Prospective Study Of Remissions, Relapses, And The Effects Of Personality Disorder Psychopathology, Carlos M. Grilo, Maria E. Pagano, Andrew E. Skodol, Charles A. Sanislow, Thomas H. Mcglashan, John G. Gunderson, Robert L. Stout

Charles A. Sanislow, Ph.D.

OBJECTIVE: To examine prospectively the natural course of bulimia nervosa and eating disorder not otherwise specified (EDNOS) and to test for the effects of personality disorder psychopathology on remission and relapse.

METHOD: Subjects were 92 female patients with current bulimia nervosa (N = 23) or EDNOS (N = 69) at baseline enrollment in the Collaborative Longitudinal Personality Disorders Study. Axis I psychiatric disorders (including eating disorders) were assessed with the Structured Clinical Interview for DSM-IV Axis I Disorders-Patient Version, and personality disorders were assessed with the Diagnostic Interview for DSM-IV Personality Disorders (DIPD-IV). The course of eating disorders was assessed …

Personality Traits Predict Current And Future Functioning Comparably For Individuals With Major Depressive And Personality Disorders, Christopher J. Hopwood, Leslie C. Morey, M. Tracie Shea, Thomas H. Mcglashan, Charles A. Sanislow, Carlos M. Grilo, John G. Gunderson, Mary C. Zanarini, Andrew E. Skodol

Charles A. Sanislow, Ph.D.

Axes I and II were separated in DSM-III to encourage the consideration of the influence of both personality and psychopathology on patient behavior, on the assumption that an understanding of personality would increment syndromal diagnosis in treatment decisions. However, in practice the distinction between Axis I and Axis II is less clear. The current report investigates one aspect on which Axis I and Axis II might be expected to differ, that being the the significance of normative personality traits as an influence on functional status. In this study, the contribution of normative personality traits to functioning is presented for 2 …

Longitudinal Effects Of Personality Disorders On Psychosocial Functioning Of Patients With Major Depressive Disorder, John C. Markowitz, Andrew E. Skodol, Eva Petkova, Jianfeng Cheng, Charles A. Sanislow, Carlos M. Grilo, John G. Gunderson, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

OBJECTIVE: No previous research has focused on psychosocial functioning in understanding how personality disorders compound the impairment caused by major depressive disorder over time. This report describes the effects of persistent and remitting comorbid personality disorders on the depressive status and functioning of patients with major depressive disorder over the course of 2 years.

METHOD: Longitudinal data on functioning from the first 2 years of the Collaborative Longitudinal Personality Disorders Study were evaluated for 3 groups of subjects with major depressive disorder: subjects with major depressive disorder alone (N = 103), those with persistent comorbid personality disorders (N = 164), …

Descriptive And Longitudinal Observations On The Relationship Of Borderline Personality Disorder And Bipolar Disorder, John G. Gunderson, Igor Weinberg, Maria T. Daversa, Karsten D. Kueppenbender, Mary C. Zanarini, M. Tracie Shea, Andrew E. Skodol, Charles A. Sanislow, Shirley Yen, Leslie C. Morey, Carlos M. Grilo, Thomas H. Mcglashan, Robert L. Stout, Ingrid R. Dyck

Charles A. Sanislow, Ph.D.

OBJECTIVE: The purpose of this study was to test whether borderline personality disorder is a variant of bipolar disorder by examining the rates of co-occurrence in both disorders, the effects of co-occurrence on a longitudinal course, and whether the presence of either disorder confers the risk for new onsets of the other.

METHOD: A prospective repeated-measures design with reliable independent diagnostic measures and 4 years of follow-up was used to assess 196 patients with borderline personality disorder and 433 patients with other personality disorders.

RESULTS: Patients with borderline personality disorder had a significantly higher co-occurrence of bipolar disorder (19.4%) than …

Prospective Assessment Of Treatment Use By Patients With Personality Disorders, Donna S. Bender, Andrew E. Skodol, Maria E. Pagano, Ingrid R. Dyck, Carlos M. Grilo, M. Tracie Shea, Charles A. Sanislow, Mary C. Zanarini, Shirley Yen, Thomas H. Mcglashan, John G. Gunderson

Charles A. Sanislow, Ph.D.

OBJECTIVE: This study examined the utilization of mental health treatments over a three-year period among patients with schizotypal, borderline, avoidant, or obsessive-compulsive personality disorders compared with patients with major depressive disorder and no personality disorder.

METHODS: A prospective, longitudinal study design was used to measure treatment use for 633 individuals aged 18 to 45 years during a three-year period.

RESULTS: Patients with borderline personality disorder were significantly more likely than those with major depressive disorder to use most types of treatment. Furthermore, all patients continued using high-intensity, low-duration treatments throughout the study period, whereas individual psychotherapy attendance declined significantly after …

Differential Impairment As An Indicator Of Sex Bias In Dsm-Iv Criteria For Four Personality Disorders, Christina D. Boggs, Leslie C. Morey, Andrew E. Skodol, M. Tracie Shea, Charles A. Sanislow, Carlos M. Grilo, Thomas H. Mcglashan, Mary C. Zanarini, John G. Gunderson

Charles A. Sanislow, Ph.D.

The aim of the present study was to investigate the possibility of sex bias in the diagnostic criteria for borderline, schizotypal, avoidant, and obsessive-compulsive personality disorders. A clinical sample of 668 individuals was evaluated for personality disorder criteria using a semistructured interview, and areas of functional impairment were assessed with both self-report and semistructured interview. The authors used a regression model of bias to identify bias as differences in slopes or intercepts between men and women in the relationship between each diagnostic criterion and level of impairment. The results suggest that most of the diagnostic criteria examined do not seem …

The Collaborative Longitudinal Personality Disorders Study (Clps): Overview And Implications, Andrew E. Skodol, John G. Gunderson, M. Tracie Shea, Thomas H. Mcglashan, Leslie C. Morey, Charles A. Sanislow, Donna S. Bender, Carlos M. Grilo, Mary C. Zanarini, Shirley Yen, Maria E. Pagano, Robert L. Stout

Charles A. Sanislow, Ph.D.

The Collaborative Longitudinal Personality Disorders Study (CLPS; Gunderson et al., 2000) was developed to fill gaps in our understanding of the nature, course, and impact of personality disorders (PDs). Here, we review published findings to date, discuss their implications for current conceptualizations of PDs, and raise questions that warrant future consideration. We have found that PDs are more stable than major depressive disorder, but that meaningful improvements are possible and not uncommon. We have confirmed also that PDs constitute a significant public health problem, with respect to associated functional impairment, extensive treatment utilization, negative prognostic impact on major depressive disorder, …

Dimensional Representations Of Dsm-Iv Personality Disorders: Relationships To Functional Impairment, Andrew E. Skodol, John M. Oldham, Donna S. Bender, Ingrid R. Dyck, Robert L. Stout, Leslie C. Morey, M. Tracie Shea, Mary C. Zanarini, Charles A. Sanislow, Carlos M. Grilo, Thomas H. Mcglashan, John G. Gunderson

Charles A. Sanislow, Ph.D.

OBJECTIVE: This study compared three-dimensional representations of DSM-IV personality disorders and standard categories with respect to their associations with psychosocial functioning.

METHOD: Six hundred sixty-eight patients with semistructured interview diagnoses of schizotypal, borderline, avoidant, or obsessive-compulsive personality disorders or with major depressive disorder and no personality disorder completed questionnaires assessing three-factor and five-factor dimensional models of personality. Personality disorder categories, dimensional representations of the categories based on criteria counts, and three- and five-factor personality dimensions were compared on their relationships to impairment in seven domains of functioning, as measured by the Longitudinal Interval Follow-up Evaluation-Baseline Version.

RESULTS: Both the categorical …

Longitudinal Comparison Of Depressive Personality Disorder And Dysthymic Disorder, John C. Markowitz, Andrew E. Skodol, Eva Petkova, Hui Xie, Jianfeng Cheng, David J. Hellerstein, John G. Gunderson, Charles A. Sanislow, Carlos M. Grilo, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

BACKGROUND: Few studies have compared the related diagnostic constructs of depressive personality disorder (DPD) and dysthymic disorder (DD). The authors attempted to replicate findings of Klein and Shih in longitudinally followed patients with personality disorder or major depressive disorder (MDD) in the Collaborative Longitudinal Personality Disorders Study.

METHODS: Subjects (N = 665) were evaluated at baseline and over 2 years (n = 546) by reliably trained clinical interviewers using semistructured interviews and self-report personality questionnaires.

RESULTS: Only 44 subjects (24.6% of 179 DPD and 49.4% of 89 early-onset dysthymic subjects) met criteria for both disorders at baseline. Depressive personality disorder …

Two-Year Prevalence And Stability Of Individual Dsm-Iv Criteria For Schizotypal, Borderline, Avoidant, And Obsessive-Compulsive Personality Disorders: Toward A Hybrid Model Of Axis Ii Disorders, Thomas H. Mcglashan, Carlos M. Grilo, Charles A. Sanislow, Elizabeth Ralevski, Leslie C. Morey, John G. Gunderson, Andrew E. Skodol, M. Tracie Shea, Mary C. Zanarini, Donna S. Bender, Robert L. Stout, Shirley Yen, Maria E. Pagano

Charles A. Sanislow, Ph.D.

OBJECTIVE: This study tracked the individual criteria of four DSM-IV personality disorders-borderline, schizotypal, avoidant, and obsessive-compulsive personality disorders-and how they change over 2 years.

METHOD: This clinical sample of patients with personality disorders was derived from the Collaborative Longitudinal Personality Disorders Study and included all participants with borderline, schizotypal, avoidant, or obsessive-compulsive personality disorder for whom complete 24-month blind follow-up assessments were obtained (N=474). The authors identified and rank-ordered criteria for each of the four personality disorders by their variation in prevalence and changeability (remission) over time.

RESULTS: The most prevalent and least changeable criteria over 2 years were paranoid …

Stability Of Functional Impairment In Patients With Schizotypal, Borderline, Avoidant, Or Obsessive Compulsive Personality Disorder Over Two Years, Andrew E. Skodol, Maria E. Pagano, Donna S. Bender, M. Tracie Shea, John G. Gunderson, Shirley Yen, Robert L. Stout, Leslie C. Morey, Charles A. Sanislow, Carlos M. Grilo, Mary C. Zanarini, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

BACKGROUND: A defining feature of personality disorder (PD) is an enduring pattern of inner experience and behavior that is stable over time. Follow-up and follow-along studies have shown considerable diagnostic instability of PDs, however, even over short intervals. What, then, about personality disorder is stable? The purpose of this study was to determine the stability of impairment in psychosocial functioning in patients with four different PDs, in contrast to patients with major depressive disorder (MDD) and no PD, prospectively over a 2-year period.

METHOD: Six hundred treatment-seeking or treated patients were recruited primarily from clinical services in four metropolitan areas …
