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 …

Preliminary Evidence For Medication Effects On Functional Abnormalities In The Amygdala And Anterior Cingulate In Bipolar Disorder, Hilary P. Blumberg, Nelson H. Donegan, Charles A.

RATIONALE: Abnormal amygdala and frontocortical responses to emotional stimuli are implicated in bipolar disorder (BD) and have been proposed as potential treatment targets.

OBJECTIVES: The aim of this study was to investigate amygdala and frontocortical responses to emotional face stimuli in BD and the influences of mood-stabilizing medications on these responses.

METHODS: Functional magnetic resonance imaging was performed while 17 BD participants (5 unmedicated) and 17 healthy comparison (HC) participants viewed faces with happy, sad, fearful, or neutral expressions.

RESULTS: The group by stimulus-condition interaction was significant (p<0.01) for amygdala activation, with the greatest effects in the happy face condition. Relative to HC, amygdala increases were greater in unmedicated BD, but lower in medicated BD. Rostral anterior cingulate (rAC) activation was decreased in unmedicated BD compared to HC; however, BD participants taking medication demonstrated rAC activation similar to HC participants.

CONCLUSIONS: Although the sample sizes were small, these preliminary results suggest that …

When Red Lights Look Yellow, Joanne M. Wood, David A. Atchison, Alex Chaparro

Publications

Purpose. Red signals are typically used to signify danger. This study was conducted to investigate a situation identified by train drivers in which red signals appear yellow when viewed at long distances (∼900 m) through progressive-addition lenses.

Methods. A laboratory study was conducted to investigate the effects of defocus, target size, ambient illumination, and surround characteristics on the extent of the color misperception of train signals by nine visually normal participants. The data from the laboratory study were validated in a field study by measuring the amounts of defocus and the distances at which the misperception of the color of …

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 …

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 …

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 …

The Application Of The Transtheoretical Model Of Change To Self-Care Behaviors In Type 2 Diabetics, Heather N. Mercer

Loma Linda University Electronic Theses, Dissertations & Projects

Background. The Transtheoretical Model of Change (TTM) has been investigated as a model of health behavior change; however, it has only begun to gain recognition in the diabetic population, and has not yet been investigated as it relates to the full-spectrum of diabetes self-care behaviors.

Purpose. The purpose of this study was to compare the pattern of stages of change across four self-care behaviors between intervention and control groups, and examine psychosocial and health outcome variables.

Method. In a cross-sectional design, a sample of 132 adult subjects with type 2 diabetes completed surveys. The survey assessed stages of change among …

Psychological Stress And High Sensitivity C-Reactive Protein Levels In Overweight And Obese Men, Olivia L. Moses

Loma Linda University Electronic Theses, Dissertations & Projects

Background and Purpose. High sensitivity C-reactive protein (hs-CRP), a measure of inflammatory response, is now considered an independent marker for coronary heart disease. Psychological stress also affects the immune system and influences the inflammatory response. Ladwig, et al (2003) found a significant positive association between hs-CRP levels and depression (F=4.9, p^.008) in 726 obese males, even after adjusting for smoking, high blood pressure and age. This study investigated if there was a similar association between increased hs-CRP levels and psychological stress in overweight and obese males.

Method. Sixty-one overweight (n=28) or obese (n= 33) males, ages 20-35, were recmited …

Religious Problem Solving And Coping With End Stage Renal Disease, Eva Bella Martinez

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined the impact of end-stage renal disease life-related couple/family stressors and strains on marital satisfaction, parental satisfaction, life satisfaction, and depression on end-stage renal disease patients and their spouses, as well as quality of life for patients. Also, it examined the moderating effects of three styles of religious problem-solving on the relationship between the ESRD couple/family stressors and strains and the outcome variables. Data included a sample of two hundred subjects and their spouses. Subjects were recruited from seven dialysis centers in southern California. Both patients and spouses were given survey questionnaires (i.e. Personal History Inventory, Religious Problem-Solving …

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 …

Two-Year Prospective Naturalistic Study Of Remission From Major Depressive Disorder As A Function Of Personality Disorder Comorbidity, Carlos M. Grilo, Charles A. Sanislow, M. Tracie Shea, Andrew E. Skodol, Robert L. Stout, John G. Gunderson, Shirley Yen, Donna S. Bender, Maria E. Pagano, Mary C. Zanarini, Leslie C. Morey, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

In this study, the authors examined prospectively the 24-month natural course of remission from major depressive disorder (MDD) as a function of personality disorder (PD) comorbidity. In 302 participants (196 women, 106 men), psychiatric and PDs were assessed at baseline with diagnostic interviews, and the course of MDD was assessed with the Longitudinal Interval Follow-Up Evaluation at 6-, 12-, and 24-month follow-ups. Survival analyses revealed an overall 24-month remission rate of 73.5% for MDD that differed little by gender. Participants with MDD who had certain forms of coexisting PD psychopathology (schizotypal, borderline, or avoidant) as their primary PD diagnoses had …

Recent Life Events Preceding Suicide Attempts In A Personality Disorder Sample: Findings From The Collaborative Longitudinal Personality Disorders Study, Shirley Yen, Maria E. Pagano, M. Tracie Shea, Carlos M. Grilo, John G. Gunderson, Andrew E. Skodol, Thomas H. Mcglashan, Charles A. Sanislow, Donna S. Bender, Mary C. Zanarini

Charles A. Sanislow, Ph.D.

Few studies have examined the relationship between life events, suicide attempts, and personality disorders (PDs), in spite of the strong associations between PDs and suicidal behavior, and the poor coping strategies often exhibited by these individuals. The authors examined whether participants with PDs who attempted suicide during the first 3 years of a prospective, longitudinal study were more likely to experience specific life events in the month during and preceding the suicide attempt. Of 489 participants with PDs, 61 attempted suicide during the 3-year, follow-up interval. Results indicated that negative life events, particularly those pertaining to love-marriage or crime-legal matters, …

Deference, Denial, And Exclusion: Men Talk About Contraception And Unintended Pregnancy, Scott D. Johnson, Lindy B. Williams

Rhetoric and Communication Studies Faculty Publications

Individual in-depth interviews were conducted with 20 men, ages 21-48, who have fathered at least one unintended pregnancy. The goal of the interviews was to explore the experiences of these men with unintended pregnancy, their communication with partners and others, contraceptive beliefs and practices, their relationships with their partners, and the outcomes and consequences of the unintended pregnancies. This essay describes results derived from their comments regarding their contraceptive practices and the pregnancy-outcome decisions, with thematic analysis used to identify prominent themes from participant comments. Two strong themes, "deference" and "denial," and one lesser theme, "exclusion," emerged from participant responses. …

Weight Loss Practices In Amateur Wrestlers And Its Relationship To Disordered Eating, Lyndsey M. Manderfield

Graduate Research Papers

The premise behind many athletic programs is to encourage wellness, a state of well being in both physical and emotional aspects.

Men, Muscles, And Body Image: Comparisons Of Competitive Bodybuilders, Weight Trainers, And Athletically Active Controls, T. C. Pickett, R. J. Lewis, T. F. Cash, H. G. Pope

Psychology Faculty Publications

Objectives: To investigate body image and psychosocial adjustment among competitive bodybuilders, non-competitive weight trainers, and athletically active men.

Methods: Participants were 40 men in each of the three groups who were assessed on body composition and multiple facets of body image evaluation, investment and anxiety, eating attitudes, and social self esteem.

Results: Relative to the other two groups, competitive bodybuilders had greater body mass due to fat-free body mass. Although groups did not differ in their situational body image discomfort, competitive bodybuilders and weight trainers had a more positive global appearance evaluation and were more psychologically invested in their physical …

Early Oral-Motor Interventions For Pediatric Feeding Problems: What, When And How, C. J. Manno, C. Fox, P. S. Eicher, Mary Louise Kerwin

Faculty Scholarship for the College of Science & Mathematics

Children with developmental delays often have feeding difficulties resulting from oral-motor problems. Based on both clinical experience and a review of published studies, oral-motor interventions have been shown to be effective in improving the oral function of preterm infants and children with neuromotor disorders, such as cerebral palsy. However, oral-motor problems may be under identified in other populations of children with developmental difficulties. The purpose of this paper is to provide a conceptual framework for understanding oral-motor skill development and problems that can occur in any infant and young child and to review oral-motor treatment techniques and their empirical support.
