Investigating The Quality Of Life For Children With Autism Spectrum Disorder Scale Using Rasch Methodology, Laura C. Chezan, Jin Liu, Ruiqin Gao, Erik Drasgow

Communication Disorders & Special Education Faculty Publications

Our purpose in this study was to provide additional psychometric evidence of the Quality of Life for Children with Autism Spectrum Disorder (QOLASD-C) scale. We used Rasch modeling to investigate the QOLASD-C functioning, the characteristics of the items comprising the scale, and the item functioning across subgroups of children with ASD based on gender and race/ethnicity. Results showed that QOLASD-C was unidimensional, met the local independence assumption, and measured quality of life (QOL). The items showed excellent fit to the model and good discriminating ability between low and high QOL. Most items showed a moderate difficulty level. No differential item …

The Program To Reduce Implicit Bias In Carroll Hospital Center Using The Implicit Association Test, Katherine E. Traynor

Capstone Showcase

Natural brain processes make all individuals susceptible to unconscious bias; however, stressful, fearful, or anger-evoking situations as well as the negative influence of media and social surroundings increase the risk of holding obstructive bias, and there is a greater risk of being negatively impacted by this phenomenon when belonging to a minority population (Rose & Flores, 2020). As a result, high rates of infant mortality (10.2 deaths per 1,000 live births for the Non-Hispanic Black population compared to 4.1 in the White population) and cardiovascular related diseases (190.0 cases per 1,000 in the Non-Hispanic Black population compared to 161.3 in …

Surgical Perioperative Leadership: The Association Between Leadership Style And Team Job Satisfaction, Corey Louise Jamison

Walden Dissertations and Doctoral Studies

Abstract

The perioperative operating room (OR) is a highly complex, fast-paced environment where countless transactions must be executed with efficiency, speed, and accuracy, and where mistakes of any kind could lead to adverse patient outcome, injury, or death. The surgeon, as leader of the procedure and the OR team, sets the overall climate of the OR and determines how willing (or unwilling) team members are to speak up about potential errors or unsafe patient conditions. This exploration of the relationship between perioperative surgeon leadership style and OR team member job satisfaction fills a gap unaddressed in the literature using items …

Examining Fear Of Recurrence In Cancer Survivors, Christina L. Dixon

Walden Dissertations and Doctoral Studies

Improvements in the medical field have given many cancer patients and survivors better odds of long-term survival. As more patients become survivors, the demand for psychological treatment becomes greater. The most prevalent concern of survivors is getting help with a psychosocial condition known as fear of recurrence (FOR). Prior to this study, few researchers had explored how having a more aggressive cancer influences the development of FOR. The purpose of this quantitative study was to determine whether cancer stage and type (a measurement of severity) are predictive of FOR development in the high-risk cancer groups lung and bronchus and female …

Child Sexual Abuse And Prenatal Care: Understanding Screening, Modifications, And Proper Care, Wendy Abbott-Egnor

Walden Dissertations and Doctoral Studies

Research has shown that 1 in 9 women in prenatal care have a history of childhood sexual abuse. Pregnant women with a history of childhood sexual abuse are at increased risk of depression, somatization, preterm contractions, posttraumatic stress symptomology, and re-traumatization. The purpose of this study was to bridge the gap in literature between research and practice. Data was collected from practitioners regarding the care and treatment of pregnant women with a childhood sexual abuse history. It was hypothesized that screening practices and modification to care and treatment based on practitioner knowledge of prior sex abuse history will vary by …

Examining The Durability Of Peers For Adolescents With Asd: Maintenance Of Neurological And Behavioral Effects, Bridget Kathleen Dolan

Dissertations (1934 -)

To date, there are no known published studies that have assessed the maintenance of treatment effects in the context of neurological changes and their relationship to behavioral outcomes following a social skills intervention for adolescents with Autism Spectrum Disorder (ASD). The few studies that have incorporated long-term assessment into their design have focused exclusively on sustained behavioral responses to treatment. Individuals with ASD across the lifespan exhibit aberrant neural activity, which is thought to underlie social skill deficits noted in persons on the spectrum. Thus, this study sought to examine the impact of a social skills intervention, the Program for …

Antenatal Stressful Life Events And Postpartum Depression In The United States: The Role Of Women’S Socioeconomic Status At The State Level, Soumyadeep Mukherjee

FIU Electronic Theses and Dissertations

The purpose of this dissertation was to examine patterns of antenatal stressful life events (SLEs) experienced by women in the United States (U.S.) and their association with postpartum depression (PPD). It further explored the role of women's state-level socio-economic status (SES) on PPD; the racial/ethnic dispartites in SLE-PPD relationship; and the role of provider communication on perinatal depression.

Data from 2009–11 Pregnancy Risk Assessment Monitoring System (PRAMS) and SES indicators published by the Institute of Women’s Policy Research (IWPR) were used. Latent class analysis (LCA) was performed to identify unobserved class membership based on antenatal SLEs. Multilevel generalized linear mixed …

Socioeconomic-Status And Mental Health In A Personality Disorder Sample: The Importance Of Neighborhood Factors, Zach Walsh, M. Tracie Shea, Shirley Yen, Emily B. Ansell, Carlos M. Grilo, Thomas H. Mcglashan, Robert L. Stout, Donna S. Bender, Andrew E. Skodol, Charles A. Sanislow, Leslie C. Morey, John G. Gunderson

Charles A. Sanislow, Ph.D.

This cross-sectional study examined the associations between neighborhood-level socioeconomic-status (NSES), and psychosocial functioning and personality pathology among 335 adults drawn from the Collaborative Longitudinal Personality Disorders Study. Participants belonged to four personality disorder (PD) diagnostic groups: Avoidant, Borderline, Schizotypal, and Obsessive Compulsive. Global functioning, social adjustment, and PD symptoms were assessed following a minimum two-year period of residential stability. Residence in higher-risk neighborhoods was associated with more PD symptoms and lower levels of functioning and social adjustment. These relationships were consistent after controlling for individual-level socioeconomic-status and ethnicity; however, the positive association between neighborhood-level socio-economic risk and PD symptoms was …

Individuals With Single Versus Multiple Suicide Attempts Over 10 Years Of Prospective Follow-Up, Christina L. Boisseaua, Shirley Yen, John C. Markowitz, Carlos M. Grilo, Charles A. Sanislow, M. Tracie Shea, Mary C. Zanarini, Andrew E. Skodol, John G. Gunderson, Leslie C. Morey, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

Background: The study attempted to identify characteristics that differentiate multiple suicide attempters from single attempters in individuals with personality disorders (PDs) and/or major depression.

Method: Participants were 431 participants enrolled in the Collaborative Longitudinal Study of Personality Disorders from July 1996 to June 2008. Suicide attempts were assessed with the Longitudinal Interval Follow-up Evaluation at 6 and 12months, then yearly through 10years. Logistic regression was used to compare single attempters to multiple attempters on Axis I and II psychiatric disorders and personality trait variables.

Results: Twenty-one percent of participants attempted suicide during the 10years of observation, with 39 (9.0%) reporting …

Prospective Investigation Of A Ptsd Personality Typology Among Individuals With Personality Disorders, Meghan E. Mcdevitt-Murphy, M. Tracie Shea, Shirley Yen, Carlos M. Grilo, Charles A. Sanislow, John C. Markowitz, Andrew E. Skodol

Charles A. Sanislow, Ph.D.

This study investigated the replicability of a previously proposed personality typology of posttraumatic stress disorder (PTSD, and explored stability of cluster membership over a 6-month period. Participants with current PTSD (n = 156) were drawn from the Collaborative Longitudinal Personality Disorders Study (CLPS). The CLPS project tracked a large sample of individuals who met criteria for 1 of 4 target diagnoses (borderline, schizotypal, avoidant, and obsessive-compulsive) and a contrast group of individuals who met criteria for depression but no personality disorder. A cluster analysis using scales from the Schedule of Nonadaptive and Adaptive Personality yielded 3 clusters: “internalizing,” “externalizing,” and …

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 …

Interpersonal Pathoplasticity In The Course Of Major Depression, Nicole M. Cain, Emily B. Ansell, Aidan G. C. Wright, Christopher J. Hopwood, Katherine M. Thomas, Anthony Pinto, John C. Markowitz, Charles A. Sanislow, Mary C. Zanarini, M. Tracie Shea, Leslie C. Morey, Thomas H. Mcglashan, Andrew E. Skodol, Carlos M. Grilo

Charles A. Sanislow, Ph.D.

Objective: The identification of reliable predictors of course in major depressive disorder (MDD) has been difficult. Evidence suggests that the co-occurrence of personality pathology is associated with longer time to MDD remission. Interpersonal pathoplasticity, the mutually influencing nonetiological relationship between psychopathology and interpersonal traits, offers an avenue for examining specific personality vulnerabilities that may be associated with depressive course. Method: This study examined 312 participants with and without a cooccurring personality disorder diagnosis who met criteria for a current MDD episode at baseline and who were followed for 10 years in the Collaborative Longitudinal Personality Disorders Study. Results: Latent profile …

Pathological Personality Traits Among Patients With Absent, Current, And Remitted Substance Use Disorders, Christopher J. Hopwood, Leslie C. Morey, Andrew E. Skodol, Charles A. Sanislow, Carlos M. Grilo, Emily B. Ansell, Thomas H. Mcglashan, John C. Markowitz, Anthony Pinto, Shirley Yen, M. Tracie Shea, John G. Gunderson, Mary C. Zanarini, Robert L. Stout

Charles A. Sanislow, Ph.D.

Personality traits may provide underlying risk factors for and/or sequelae to substance use disorders (SUDs). In this study Schedule for Nonadaptive and Adaptive Personality (SNAP) traits were compared in a clinical sample (N=704, age 18–45) with current, past, or no historical alcohol or non-alcohol substance use disorders (AUD and NASUD) as assessed by DSM-IV semi-structured interview. Results corroborated previous research in showing associations of negative temperament and disinhibition to SUD, highlighting the importance of these traits for indicating substance use proclivity or the chronic effects of substance use. Certain traits (manipulativeness, self-harm, disinhibition, and impulsivity for AUD, and disinhibition and …

Ten-Year Course Of Borderline Personality Disorder: Psychopathology And Function From The Collaborative Longitudinal Personality Study, John G. Gunderson, Robert L. Stout, Thomas H. Mcglashan, M. Tracie Shea, Leslie C. Morey, Carlos M. Grilo, Mary C. Zanarini, Shirley Yen, John C. Markowitz, Charles A. Sanislow, Emily B. Ansell, Anthony Pinto, Andrew E. Skodol

Charles A. Sanislow, Ph.D.

Context: Borderline personality disorder (BPD) is traditionally considered chronic and intractable.

Objective: To compare the course of BPD’s psychopathology and social function with that of other personality disorders and with major depressive disorder (MDD) over 10 years. Design: A collaborative study of treatment-seeking, 18- to 45-year-old patients followed up with standardized, reliable, and repeated measures of diagnostic remission and relapse and of both global social functioning and subtypes of social functioning.

Setting: Nineteen clinical settings (hospital and outpatient) in 4 northeastern US cities.

Participants: Three study groups, including 175 patients with BPD, 312 with cluster C personality disorders, and 95 …

The Association Of Personality Disorders With The Prospective 7-Year Course Of Anxiety Disorders, Emily B. Ansell, Anthony Pinto, Maria O. Edelen, John C. Markowitz, Charles A. Sanislow, Shirley Yen, Mary C. Zanarini, Andrew E. Skodol, M. Tracie Shea, Leslie C. Morey, John G. Gunderson, Thomas H. Mcglashan, Carlos M. Grilo

Charles A. Sanislow, Ph.D.

Background. This study prospectively examined the natural clinical course of six anxiety disorders over 7 years of follow-up in individuals with personality disorders (PDs) and/or major depressive disorder. Rates of remission, relapse, new episode onset and chronicity of anxiety disorders were examined for specific associations with PDs.

Method. Participants were 499 patients with anxiety disorders in the Collaborative Longitudinal Personality Disorders Study, who were assessed with structured interviews for psychiatric disorders at yearly intervals throughout 7 years of follow-up. These data were used to determine probabilities of changes in disorder status for social phobia (SP), generalized anxiety disorder (GAD), obsessive-compulsive …

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 …

Psychometric Characteristics And Clinical Correlates Of Neo-Pi-R Fearless Dominance And Impulsive Antisociality In The Collaborative Longitudinal Personality Disorders Study, Edward A. Witt, Christopher J. Hopwood, Leslie C. Morey, John C. Markowitz, Thomas H. Mcglashan, Carlos M. Grilo, Charles A. Sanislow, M. Tracie Shea, Andrew E. Skodol, John G. Gunderson, M. Brent Donnellan

Charles A. Sanislow, Ph.D.

This study evaluates the validity of derived measures of the psychopathic personality traits of Fearless Dominance and Impulsive Antisociality from the NEO Personality Inventory-Revised (NEO-PI-R; Costa & McCrae, 1992) using data from the Collaborative Longitudinal Personality Disorders Study (baseline N = 733). These 3 issues were examined: (a) the stability of the measures over a 10-year interval, (b) their criterion-related validity, and (c) their incremental validity relative to an alternative NEO-PI-R profile-rating approach for assessing psychopathy. NEO-PI-R Fearless Dominance and Impulsive Antisociality scales were relatively stable across 10 years and demonstrated differential associations with measures of personality pathology and psychopathology …

Trajectories Of Ptsd And Substance Use Disorders In A Longitudinal Study Of Personality Disorders, Meghan E. Mcdevitt-Murphy, Gilbert R. Parra, M. Tracie Shea, Shirley Yen, Carlos M. Grilo, Charles A. Sanislow, Thomas H. Mcglashan, John G. Gunderson, Andrew E. Skodol, John C. Markowitz

Charles A. Sanislow, Ph.D.

The Stability Of Personality Traits In Individuals With Borderline Personality Disorder, Christopher J. Hopwood, Daniel A. Newman, M. Brent Donnellan, John C. Markowitz, Carlos M. Grilo, Charles A. Sanislow, Emily B. Ansell, M. Tracie Shea, Andrew E. Skodol, Thomas H. Mcglashan, John G. Gunderson, Mary C. Zanarini, Leslie C. Morey

Charles A. Sanislow, Ph.D.

Although stability and pervasive inflexibility are general criteria for Diagnostic and Statistical Manual of Mental Disorders, 4th edition (American Psychiatric Association, 1994) personality disorders (PDs), borderline PD (BPD) is characterized by instability in several domains, including interpersonal behavior, affect, and identity. The authors hypothesized that such inconsistencies notable in BPD may relate to instability at the level of the basic personality traits that are associated with this disorder. Five types of personality trait stability across 4 assessments over 6 years were compared for BPD patients (N = 130 at first interval) and patients with other PDs (N = 302). Structural …

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 …

Self-Criticism Versus Neuroticism In Predicting Depression And Psychosocial Impairment For 4 Years In A Clinical Sample, David M. Dunkley, Charles A. Sanislow, Carlos M. Grilo, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

The present study extended previous findings demonstrating self-criticism, assessed by the Dysfunctional Attitude Scale (DAS) (Weissman AN, Beck AT. Development and validation of the Dysfunctional Attitude Scale: a preliminary investigation. Paper presented at the 86th Annual Convention of the American Psychological Association, Toronto, Ontario, Canada, 1978), as a potentially important prospective predictor of depressive symptoms and psychosocial functional impairment over time. Using data from a prospective, 4-year study of a clinical sample, DAS self-criticism and neuroticism were associated with self-report depressive symptoms, interviewer-rated major depression, and global domains of psychosocial functional impairment 4 years later. Hierarchical multiple regression results indicated …

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 …

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, …

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 …

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 …

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 …

Using The Outcome Questionnaire 45.2 In Obesity Treatment, Adam L. Arechiga

Loma Linda University Electronic Theses, Dissertations & Projects

Purpose: The purpose of this study was to determine if the Outcome Questionnaire 45.2 (OQ-45) can be used in the treatment of obesity to predict participant dropout and initial treatment success, in terms of weight loss (Lambert et. al, 2002a). The OQ-45 has been used with success to predict dropout from psychotherapy in clinical populations. It was hypothesized that higher pretreatment OQ-45 scores would be associated with less program completion and less weight loss by the end of treatment.

Method: The study employed a non-experimental time series design. Seventy-eight participants were recruited from the three local obesity treatment programs, which …

Perfectionism And Depressive Symptoms 3 Years Later: Negative Social Interactions, Avoidant Coping, And Perceived Social Support As Mediators., David M. Dunkley, Charles A. Sanislow, Carlos M. Grilo, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

Although research has demonstrated perfectionism to have a negative impact on the treatment of depression, little research has examined the mechanisms or processes through which perfectionism predicts subsequent depressive symptoms in clinical populations over time. Using data from a prospective, 3-year study of a clinical sample (N = 96), hierarchical regression analyses indicated that perfectionism, assessed by the Dysfunctional Attitude Scale (Weissman AN, Beck AT. Development and validation of the Dysfunctional Attitude Scale: a preliminary investigation. Paper presented at the 86th annual convention of the American Psychological Association, Toronto, Ontario, Canada; 1978), is distinguished from major depression and neuroticism for …
