Avoidant Personality Disorder And Social Phobia: Distinct Enough To Be Separate Disorders?, Elizabeth Ralevski, Charles A. Sanislow, Carlos M. Grilo, Andrew E. Skodol, John G. Gunderson, M. Tracie Shea, Shirley Yen, Donna S. Bender, Mary C. Zanarini, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

Objective: Existing evidence from anxiety disorder research indicates that social phobics (SP) with avoidant personality disorder (AVPD) experience more anxiety and show more impairment than patients with SP alone. The purpose of this study was to examine whether in patients diagnosed with AVPD, the co-occurrence of SP adds to its severity. We hypothesized that the addition of SP will not add to the severity of AVPD alone.

Method: Two groups of patients (AVPD = 224; AVPD/SP = 101) were compared at baseline and 2 years later on multiple demographic and clinical variables.

Results: Patients with AVPD and an additional diagnosis …

Validity Of Das Perfectionism And Need For Approval In Relation To The Five-Factor Model Of Personality, David M. Dunkley, Charles A. Sanislow, Carlos M. Grilo, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

This study examined the validity of the perfectionism and need for approval scales of the Dysfunctional Attitude Scale (DAS; Weissman & Beck, 1978) by locating these measures within a comprehensive framework of personality, provided by the revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992), in a clinical sample (N ¼ 132). The results indicated that: (1) DAS perfectionism reflects the self-critical aspects of the broader perfectionism construct rather than the active achievement striving aspects; (2) DAS need for approval generally lacks an association with positive interpersonal traits and shares much in common with DAS perfectionism; and (3) with shared …

Associations In The Course Of Personality Disorders And Axis I Disorders Over Time, M. Tracie Shea, Robert L. Stout, Shirley Yen, Maria E. Pagano, Andrew E. Skodol, Leslie C. Morey, John G. Gunderson, Thomas H. Mcglashan, Carlos M. Grilo, Charles A. Sanislow, Donna S. Bender, Mary C. Zanarini

Charles A. Sanislow, Ph.D.

In this study, the authors examined time-varying associations between schizotypal (STPD), borderline (BPD), avoidant (AVPD), or obsessive-compulsive (OCPD) personality disorders and co-occurring Axis I disorders in 544 adult participants from the Collaborative Longitudinal Personality Disorders Study. The authors tested predictions of specific longitudinal associations derived from a model of crosscutting psychobiological dimensions (L. J. Siever & K. L. Davis, 1991) with participants with the relevant Axis I disorders. The authors assessed participants at baseline and at 6-, 12-, and 24-month follow-up evaluations. BPD showed significant longitudinal associations with major depressive disorder and posttraumatic stress disorder. AVPD was significantly associated with …

Temporal Coherence Of Criteria For Four Personality Disorders, Leslie C. Morey, Andrew E. Skodol, Carlos M. Grilo, Charles A. Sanislow, Mary C. Zanarini, M. Tracie Shea, John G. Gunderson, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

This study sought to investigate the coherence of changes observed in diagnostic criteria for borderline, schizotypal, obsessive-compulsive, and avoidant personality disorders. Five hundred, forty-nine patients were independently evaluated 2 years apart, and correlations of observed changes in each diagnostic criterion with changes in other criteria were examined to determine if there was within-syndrome consistency in these changes. The observed changes in criteria were consistent within syndrome (median alpha = 0.72 across 4 disorders), and reasonably specific to that syndrome relative to the other disorders. The results support the validity of these criterion sets as representing coherent syndromes.

Major Depressive Disorder And Borderline Personality Disorder Revisited: Longitudinal Interactions, John G. Gunderson, Leslie C. Morey, Robert L. Stout, Andrew E. Skodol, M. Tracie Shea, Thomas H. Mcglashan, Mary C. Zanarini, Carlos M. Grilo, Charles A. Sanislow, Shirley Yen, Maria T. Daversa, Donna S. Bender

Charles A. Sanislow, Ph.D.

BACKGROUND: This report investigates the longitudinal association of changes in major depressive disorder (MDD) and borderline personality disorder.

METHOD: A DSM-IV-diagnosed sample of 161 patients with borderline personality disorder who have been followed with repeated measures at 6, 12, 24, and 36 months are investigated to see whether those with co-occurring MDD differ at baseline and in their course. Proportional hazard regression and cross-lagged panel analyses are used to demonstrate whether changes in the course of either disorder have predictable effects on the course of the other.

RESULTS: The rate of remissions of borderline personality disorder was not affected by …

The Longitudinal Relationship Of Personality Traits And Disorders, Megan B. Warner, Leslie C. Morey, John F. Finch, John G. Gunderson, Andrew E. Skodol, Charles A. Sanislow, M. Tracie Shea, Thomas H. Mcglashan, Carlos M. Grilo

Charles A. Sanislow, Ph.D.

Personality disorders are presumed to be stable because of underlying stable and maladaptive personality traits, but while previous research has demonstrated a link between personality traits and personality disorders cross-sectionally, personality disorders and personality traits have not been linked longitudinally. This study explores the extent to which relevant personality traits are stable in individuals diagnosed with 4 personality disorders (schizotypal, borderline, avoidant, and obsessive-compulsive personality disorders) and examines the assumption that these personality disorders are stable by virtue of stable personality traits. This assumption was tested via the estimation of a series of latent longitudinal models that evaluated whether changes …

The Representation Of Four Personality Disorders By The Schedule For Nonadaptive And Adaptive Personality Dimensional Model Of Personality, Leslie C. Morey, Megan B. Warner, M. Tracie Shea, John G. Gunderson, Charles A. Sanislow, Carlos M. Grilo, Andrew E. Skodol, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

This study examined the relationships of the Schedule for Nonadaptive and Adaptive Personality (SNAP) model of personality to 4 targeted personality disorders (PDs) in a large multisite sample of patients. Data were examined from 529 patients, who were assigned 1 of 5 primary diagnoses: borderline, schizotypal, avoidant, and obsessive–compulsive PDs and major depression without PD. Patients were administered the SNAP questionnaire and results were compared among diagnostic groups and between patient groups and nonclinical norms. Results indicated that the dimensions of the model appear to have considerable promise in differentiating normal from abnormal personality, particularly in the propensity of individuals …

Gender Differences In Borderline Personality Disorder: Findings From The Collaborative Longitudinal Personality Disorders Study, Dawn M. Johnson, M. Tracie Shea, Shirley Yen, Cynthia L. Battle, Caron Zlotnick, Charles A. Sanislow, Carlos M. Grilo, Andrew E. Skodol, Donna S. Bender, Thomas H. Mcglashan, John G. Gunderson, Mary C. Zanarini

Charles A. Sanislow, Ph.D.

A majority of the literature on borderline personality disorder (BPD) focuses on its occurrence in women or does not specifically assess for gender differences in clinical presentations. Some studies report that men with BPD may be more likely to be diagnosed with substance use disorders, as well as paranoid, passive-aggressive, narcissistic, sadistic, and antisocial personality disorders (PDs). Additionally, women with BPD appear to be more likely to report histories of adult physical and sexual abuse and to meet diagnostic criteria for post-traumatic stress disorder (PTSD) and eating disorders. The purpose of the present study was to further examine gender differences …

Plausibility And Possible Determinants Of Sudden 'Remissions' In Borderline Patients, John G. Gunderson, Donna S. Bender, Charles A. Sanislow, Shirley Yen, Jennifer Bame Rettew, Regina Dolan-Sewell, Ingrid R. Dyck, Leslie C. Morey, Thomas H. Mcglashan, M. Tracie Shea, Andrew E. Skodol

Charles A. Sanislow, Ph.D.

THIS STUDY documents dramatic improvements in patients with borderline personality disorder (BPD) and explores their possible determinants. From a sample of the 160 carefully diagnosed borderline patients on whom prospective follow-along data was collected, a subsample of 18 was identified whose DSM-IV criteria count fell to two or fewer during the course of the first 6 months of the study and retained that improvement for the next 6 months. Follow-along data including month-by-month ratings of BPD criteria; week-by-week ratings of Axis I disorders, medication changes, and life events were then used to establish concensus ratings on four hypothesized causes: Axis …

Substance Or Style? An Investigation Of The Neo-Pi-R Validity Scales, Leslie C. Morey, Brian D. Quigley, Charles A. Sanislow, Andrew E. Skodol, Thomas H. Mcglashan, M. Tracie Shea, Robert L. Stout, Mary C. Zanarini, John G. Gunderson

Charles A. Sanislow, Ph.D.

The Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992b) has been criticized for the absence of validity scales designed to detect response distortion. Recently, validity scales were developed from the items of the NEO-PI-R (Schinka, Kinder, & Kremer, 1997) and several studies have used a variety of methods to test their use. However, it is controversial whether these scales are measuring something that is substantive (such as psychopathology or its absence) or stylistic (which might be effortful distortion or less conscious processes such as lack of insight). In this study, we used a multimethod-multitrait approach to examine the validity …

Confirmatory Factor Analysis Of The Dsm-Iv Criteria For Borderline Personality Disorder: Findings From The Collaborative Longitudinal Personality Disorders Study, Charles A. Sanislow, Carlos M. Grilo, Leslie C. Morey, Donna S. Bender, Andrew E. Skodol, John G. Gunderson, M. Tracie Shea, Robert L. Stout, Mary C. Zanarini, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

Objective: This study tested the factor structure of the DSM-IV criteria for borderline personality disorder by using confirmatory methods for the analysis of covariance structures in a large group from a multisite study.

Method: A total of 668 primarily treatment-seeking subjects were reliably assessed for personality disorders by using the Diagnostic Interview for DSM-IV Personality Disorders. Associations among criteria for borderline personality disorder were examined. A confirmatory factor analysis was performed to test diagnosis as a unitary construct and to test an earlier-reported three-factor model comprising disturbed relatedness, behavioral dysregulation, and affective dysregulation. The three-factor model was subsequently tested by …

Confirmatory Factor Analysis Of Dsm-Iv Schizotypal, Borderline, Avoidant, And Obsessive-Compulsive Personality Disorders: Findings From The Collaborative Longitudinal Study Of Personality Disorders, Charles A. Sanislow, Leslie C. Morey, Carlos M. Grilo, John G. Gunderson, M. Tracie Shea, Andrew E. Skodol, Robert L. Stout, Mary C. Zanarini, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

Objective: To test the diagnostic constructs implied by DSM-IV Axis-II personality disorders by examining relationships between different combinations of DSM-IV criteria.

Method: Confirmatory factor analysis was used to test the borderline, schizotypal, avoidant and obsessive-compulsive personality disorder constructs in a large treatment-seeking sample (N=668) from a multisite study. A model based on the three DSM-IV Axis II clusters was also tested. Both models were tested against a unitary ‘generic’ model constructed from four criteria sets combined.

Results: Goodness-of-fit for both the three-cluster and four disorder models was significantly better than the unidimensional model, and the four-disorder model was significantly better …

Internal Consistency And Intercriterion Overlap Within And Between Dsm-Iv Axis Ii Personality Disorders: Findings From The Collaborative Longitudinal Study Of Personality Disorders, Carlos M. Grilo, Thomas H. Mcglashan, Leslie C. Morey, John G. Gunderson, Andrew E. Skodol, M. Tracie Shea, Charles A. Sanislow, Mary C. Zanarini, Donna S. Bender, John M. Oldham, Ingrid Dyck, Robert L. Stout

Charles A. Sanislow, Ph.D.

Objective: To evaluate performance characteristics of DSM-IV Personality Disorders (PDs) criteria.

Method: Six hundred and sixty-eight adults recruited for the Collaborative Longitudinal Personality Disorders Study (CLPS) were assessed with diagnostic interviews.

Results: Within-category inter-relatedness was evaluated by Cronbach’s alpha and median intercriterion correlations (MIC). Cronbach’s alpha ranged from 0.47 to 0.87 (median=0.71); seven of the 10 PDs had alphas greater than 0.70. Between-category criterion overlap was evaluated by ‘inter-category’ intercriterion correlations between all PD pairs (ICMIC). ICMIC values (median=0.08) were lower than MIC values (median=0.23). Diagnostic efficiency statistics (sensitivity, specificity, positive predictive power and negative predictive power were calculated for …

Schizotypal Personality Questionnaire-Brief: Factor Structure And Convergent Validity In Inpatient Adolescents, Seth R. Axelrod, Carlos M. Grilo, Charles A. Sanislow, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

We examined the internal consistency, factor structure, and validity of the Schizotypal Personality Questionnaire-Brief (SPQ-B). Two hundred thirty-seven psychiatrically hospitalized adolescents were administered the SPQ-B and a battery of well-established self-report instruments. The SPQ-B demonstrated adequate internal consistency. Exploratory factor analysis provided mixed support for the SPQ-B 3-factor structure of interpersonal deficits, cognitive-perceptual deficits, and disorganization. The Interpersonal and Cognitive-Perceptual subscales demonstrated convergent and discriminant relationships with other measures of interpersonal impairment and cognitive abnormalities. We concluded that the SPQ-B is a promising measure for evaluating schizotypal personality disorder features, specifically interpersonal and cognitiveperceptual deficits, with adolescent psychiatric inpatients.

Factor Analysis Of The Dsm-Iii-R Borderline Personality Disorder Criteria In Psychiatric Inpatients, Charles A. Sanislow, Carlos M. Grilo, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

Objective: The goal of this study was to examine the factor structure of the DSM-III-R criteria for borderline personality disorder in young adult psychiatric inpatients.

Method: The authors assessed 141 acutely ill inpatients with the Personality Disorder Examination, a semistructured diagnostic interview for DSM-III-R personality disorders. They used correlational analyses to examine the associations among the different criteria for borderline personality disorder and performed an exploratory factor analysis.

Results: Cronbach’s coefficient alpha for the borderline personality disorder criteria was 0.69. A principal components factor analysis with a varimax rotation accounted for 57.2% of the variance and revealed three homogeneous factors. …

Norm-Of-Reaction: Definition And Misinterpretation Of Animal Research, Steve A. Platt, Charles A. Sanislow

Charles A. Sanislow, Ph.D.

The development of a phenotype is due to an interaction of the genotype with the environment. Two terms have been used to describe the outcome of this interaction, the norm-of-reaction and the reaction range. The first represents the theoretically limitless distribution of the phenotypes that may be expressed by a given genotype. The reaction range implies an upper and lower limit for phenotype expression possible from a given genotype. A critical distinction between the reaction range and the norm-of-reaction is that the norm-of-reaction is a statement of the conceivable interactions found but does not imply any predictability other than that …

A Comparison Of Self-Esteem And Health Locus Of Control In Adolescents With Insulin Dependent Diabetes Mellitus, Janice Mace

Loma Linda University Electronic Theses, Dissertations & Projects

This study was a descriptive survey establishing a baseline level of self-esteem and health locus of control in insulin dependent diabetes mellitus (IDDM) adolescents. The purpose of the research was to study and describe health behaviors of IDDM adolescents in regards to self-concept and health locus of control. These behaviors are believed to have life-long ramifications on the IDDM adolescent's health status.

The sample consisted of 91 IDDM adolescents, 34 male and 57 female, in a nonrandom convenience cluster attending a 10-day summer camp.

Null hypothesis one was: Insulin dependent diabetes mellitus would make no difference at the .05 level …
