Sleep Quality and Eating Disorder-Related Psychopathologies in Patients with Night Eating Syndrome and Binge Eating Disorders. J Clin Med 2021; 10:jcm10194613. [PMID: 34640635 PMCID: PMC8509793 DOI: 10.3390/jcm10194613] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2021] [Revised: 10/01/2021] [Accepted: 10/05/2021] [Indexed: 12/02/2022] Open
Abstract
Night eating syndrome (NES) is an eating disorder (ED) characterized by nocturnal ingestion (NI), evening hyperphagia, morning anorexia, as well as mood and sleep disturbances. This study compared subjective and objective sleep quality and ED-related psychopathologies in patients seeking treatment for ED. Method: The sample was composed of 170 women, aged 18–68, who were referred for an ED assessment from 2011 to 2020. The participants were divided into three subgroups: NES-NI only (n = 30), NES+ binge eating (BE) (including binge eating disorders or bulimia nervosa (n = 52), and BE-only (n = 88). The measures consisted of a psychiatric evaluation, objective sleep monitoring measured by an actigraph for 1 week, a subjective sleep self-report, and ED-related psychopathology questionnaires. Results: Objective sleep monitoring revealed significant group differences, with higher sleep efficiency in participants with BE-only and longer sleep durations for the NES-NI only group. Subjectively, the BE-only group described a significantly lower sleep quality than either the NES-NI only or the NES+BE groups. ED-related psychopathology was lower in the NES-NI-only group. A stepwise linear regression revealed that general psychopathology (the brief symptom inventory total score) was a significant predictor of subjective sleep quality. Conclusion: NES-NI-only was correlated with less psychopathology, but with more subjective and objective sleep disturbances. These results lend weight to the supposition that NES lies on a continuum of ED psychopathologies, and that NES-NI-only appears to be a separate entity from NES+BE and BE-only in terms of its psychopathology.

Yang J, Han KS. A rational emotive behavior therapy-based intervention for binge eating behavior management among female students: a quasi-experimental study. J Eat Disord 2020; 8:65. [PMID: 33292605 PMCID: PMC7709400 DOI: 10.1186/s40337-020-00347-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Accepted: 10/28/2020] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Binge eating behavior is highly likely to progress to an eating disorder, with female students particularly at risk. OBJECTIVE This study aimed to verify the effect of a binge eating behavior management program, based on rational emotive behavior therapy (REBT), on binge eating behavior and related cognitive and emotional factors among female college students. METHOD The study, conducted from November 1 to December 2, 2016, involved a pretest-posttest design and nonequivalent control group. The sample included 24 and 22 first- to third-year students, from a college in South Korea, in the experimental and control groups, respectively. Data were collected using self-esteem, covert narcissism, perfectionism, body dissatisfaction, anxiety, depression, and binge eating scales and analyzed via frequency analysis, χ2 tests, t tests, and analysis of covariance. RESULTS The results indicated that the REBT-based binge eating behavior management program exerted positive effects on participants' self-esteem, reducing covert narcissism, body dissatisfaction, anxiety, depression, and binge eating. However, there was no significant difference in perfectionism, although the experimental group's mean score decreased from pretest to posttest. CONCLUSIONS Based on the results, the program was considered to be effective, and is expected to be useful in preventing the development of eating disorders among female college students by treating binge eating behavior and related cognitive and emotional factors. This intervention could ultimately contribute to the improvement of female college students' health and quality of life.

Abstract
This study compared women with binge eating disorders or bulimia nervosa with and without night eating syndrome regarding childhood maltreatment and psychopathology relative to healthy controls. The 426 participants (aged 18-60) were divided into two groups: eating disorders (n = 158) and healthy controls (n = 268). Eating disorders was divided into bulimia nervosa, binge eating disorder, and night eating syndrome with binge eating. Participants completed questionnaires: childhood trauma, eating disorders, self-esteem, and psychopathology. No significant differences were found for most variables in the eating disorders subgroups except physical neglect, which was more prevalent in night eating syndrome with binge eating. All variables differed significantly between eating disorders and healthy controls. Significant correlations emerged between childhood maltreatment, psychopathology, emotional abuse, and self-esteem in eating disorders. Regression showed that emotional abuse significantly predicted self-esteem in eating disorders, and group significantly moderated the effect of emotional abuse on psychopathology. Results emphasize that in this specific sample and variables, night eating syndrome with binge eating may be a variant of binge eating disorder or bulimia nervosa and not a separate diagnostic entity. The results highlight the importance of early assessment of childhood maltreatment, particularly emotional abuse, in patients with night eating syndrome.

Eating disorder recovery is associated with absence of major depressive disorder and substance use disorders at 22-year longitudinal follow-up. Compr Psychiatry 2019; 90:49-51. [PMID: 30685636 PMCID: PMC6420843 DOI: 10.1016/j.comppsych.2019.01.002] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2018] [Revised: 12/20/2018] [Accepted: 01/09/2019] [Indexed: 12/04/2022] Open
Abstract
BACKGROUND Psychiatric comorbidity is common in eating disorders (EDs) and associated with poor outcomes, including increased risk for relapse and premature death. Yet little is known about comorbidity following ED recovery. METHODS We examined two common comorbidities, major depressive disorder (MDD) and substance use disorder (SUD), in adult women with intake diagnoses of anorexia nervosa and bulimia nervosa who participated in a 22-year longitudinal study. One hundred and seventy-six of 228 surviving participants (77.2%) were interviewed 22 years after study entry using the Eating Disorders Longitudinal Interval Follow-up Evaluation to assess ED recovery status. Sixty-four percent (n = 113) were recovered from their ED. The Structured Clinical Interview for DSM-IV was used to assess MDD and SUD at 22 years. RESULTS At 22-year follow-up, 28% (n = 49) met criteria for MDD, and 6% (n = 11) met criteria for SUD. Those who recovered from their ED were 2.17 times more likely not to have MDD at 22-year follow-up (95% CI [1.10, 4.26], p = .023) and 5.33 times more likely not to have a SUD at 22-year follow-up than those who had not recovered from their ED (95% CI [1.36, 20.90], p = .008). CONCLUSION Compared to those who had not fully recovered from their ED, those who had recovered were twice as likely not to be diagnosed with MDD in the past year and five times as likely not to be diagnosed with SUDs in the past year. These findings provide evidence that long-term recovery from EDs is associated with recovery from or absence of these common major comorbidities. Because comorbidity in EDs can predict poor outcomes, including greater risk for relapse and premature death, our findings of reduced risk for psychiatric comorbidity following recovery at long-term follow-up is cause for optimism.

Increased Functional Connectivity Between Ventral Attention and Default Mode Networks in Adolescents With Bulimia Nervosa. J Am Acad Child Adolesc Psychiatry 2019; 58:232-241. [PMID: 30738550 PMCID: PMC6462410 DOI: 10.1016/j.jaac.2018.09.433] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2018] [Revised: 09/19/2018] [Accepted: 10/22/2018] [Indexed: 11/20/2022]
Abstract
OBJECTIVE Bulimia nervosa (BN) is characterized by excessive attention to self and specifically to body shape and weight, but the ventral attention (VAN) and default mode (DMN) networks that support attentional and self-referential processes are understudied in BN. This study assessed whether altered functional connectivity within and between these networks contributes to such excessive concerns in adolescents with BN early the course of the disorder. METHOD Resting-state functional magnetic resonance images were acquired from 33 adolescents with BN and 37 healthy control adolescents (12-21 years) group matched by age and body mass index. Region-of-interest analyses were performed to examine group differences in functional connectivity within and between the VAN and DMN. In addition associations of VAN-DMN connectivity with BN symptoms, body shape/weight concerns, and sustained attention were explored using the Continuous Performance Test (CPT). RESULTS Compared with control adolescents, those with BN showed significantly increased positive connectivity between the right ventral supramarginal gyrus and all DMN regions and between the right ventrolateral prefrontal cortex and the left lateral parietal cortex. Within-network connectivity did not differ between groups. VAN-DMN connectivity was associated with BN severity and body shape/weight concerns in the BN group. No significant group-by-CPT interactions on VAN-DMN connectivity were detected. CONCLUSION Increased positive VAN-DMN connectivity in adolescents with BN could reflect abnormal engagement of VAN-mediated attentional processes at rest, perhaps related to their excessive attention to self-referential thoughts about body shape/weight. Future studies should further investigate these circuits as targets for the development of early interventions aimed at decreasing excessive body shape/weight concerns.

Abstract
In our review, we focus on self-related constructs in the context of eating disorders with four aims. First, we examine a variety of self-related constructs that have been theoretically and empirically linked to the development and course of eating disorders. In addition to the more well-researched constructs of self-esteem and self-efficacy, we also report on findings related to selflessness, contingent self-worth, self-objectification, ego-syntonicity, self-concept clarity, self-compassion, social comparison, self-oriented perfectionism/self-criticism, and narcissism. Second, we discuss self-related constructs that may be especially relevant to comorbidities common among those with eating disorders. Third, we review intervention and prevention programs where self-related constructs play a prominent role. Lastly, we share future research directions regarding self-related constructs and eating disorders that we believe will advance a deeper understanding of the role of the self in the eating disorders.

Abstract
UNLABELLED Body image disturbances are a prominent feature of eating disorders (EDs). Our aim was to test and evaluate a computerized assessment of body image (CABI), to compare the body image disturbances in different ED types, and to assess the factors affecting body image. The body image of 22 individuals undergoing inpatient treatment with restricting anorexia nervosa (AN-R), 22 with binge/purge AN (AN-B/P), 20 with bulimia nervosa (BN), and 41 healthy controls was assessed using the Contour Drawing Rating Scale (CDRS), the CABI, which simulated the participants' self-image in different levels of weight changes, and the Eating Disorder Inventory-2-Body Dissatisfaction (EDI-2-BD) scale. Severity of depression and anxiety was also assessed. Significant differences were found among the three scales assessing body image, although most of their dimensions differentiated between patients with EDs and controls. Our findings support the use of the CABI in the comparison of body image disturbances in patients with EDs vs. CONTROLS Moreover, the use of different assessment tools allows for a better understanding of the differences in body image disturbances in different ED types.

Negative affective experiences in relation to stages of eating disorder recovery. Eat Behav 2014; 15:24-30.

Abstract
The purpose of this study was to examine a collection of negative affect symptoms in relation to stages of eating disorder recovery. Depressive symptoms, anxiety symptoms, loneliness, and perceived stress are known to be present in individuals with eating disorders; however, less is known about the presence of such constructs throughout the recovery process. Does this negative affect fog continue to linger in individuals who have recovered from an eating disorder? Female participants seen at some point for an eating disorder at a primary care clinic were categorized into one of three groups using a stringent definition of eating disorder recovery based on physical, behavioral, and psychological criteria: active eating disorder (n=53), partially recovered (n=15; psychological criteria not met), and fully recovered (n=20; all recovery criteria met). Additionally, data were obtained from 67 female controls who had no history of an eating disorder. Self-report data indicated that controls and women fully recovered from an eating disorder scored significantly lower than partially recovered and active eating disorder groups in perceived stress, depression, and anxiety. Controls and the fully recovered group were statistically indistinguishable from each other in these domains, as were the partially recovered and active eating disorder groups, suggesting an interesting divide depending on whether psychological criteria (e.g., normative levels of weight/shape concern) were met. In contrast, controls and fully recovered and partially recovered groups all reported feeling significantly less lonely relative to those with an active eating disorder suggesting that improved perceptions of interpersonal functioning and social support may act as a stepping stone toward more comprehensive eating disorder recovery. Future research may want to longitudinally determine if an increase in actual or perceived social support facilitates the movement toward full recovery and whether this, in turn, has salutatory effects on depression, anxiety, and perceived stress.

Abstract
SummaryObjective - The question of how many psychopathologic factors are involved in Anorexia Nervosa (AN) and Bulimia Nervosa (BN) has no definite answer. The combination of psychopathology and personality research may shed a light upon the determinants of eating pathology. Methods - The study consists inthe administration of the Temperament and Character Inventory (TCI) and the Eating Disorder Inventory 2 (EDI-2) to 95 outpatient anorectic women (50 restrictive and 45 binge-purging) and to 92 bulimic outpatientwomen (78 with and 14 without purging behaviours). The respective scores of each DCA subgroup are compared. Results - Restricter anorectics are characterised by lower novelty seeking on respect to all the other groups and by a higher self-directedness on respect to bingeing-purging anorectics and purging bulimics. Alsopsychopathologic differences between restricter anorectics and the other groups are extensive. Bingeing-purging anorexia shares many traits with bulimia. Conclusions - In their complex, data suggest and in-deep study aimed to a possible re-classification of EDs which would take impulsiveness in greater consideration. The differences in temperament and character traits may partially be responsible of the repression or discontrol of impulsive eating behaviours in different ED subtypes.Declaration of InterestAuthors received grants and research support from Regione Piemonte (Project no. 19701/27001).

Abstract
The authors applied person-environment transaction theory to test the acquired preparedness model of eating disorder risk. The model holds that (a) middle-school girls high in the trait of ineffectiveness are differentially prepared to acquire high-risk expectancies for reinforcement from dieting or thinness; (b) those expectancies predict subsequent binge eating and purging; and (c) the influence of the disposition of ineffectiveness on binge eating and purging is mediated by dieting or thinness expectancies. In a three-wave longitudinal study of 394 middle-school girls, the authors found support for the model. Seventh-grade girls' scores on ineffectiveness predicted their subsequent endorsement of high-risk dieting or thinness expectancies, which in turn predicted subsequent increases in binge eating and purging. Statistical tests of mediation supported the hypothesis that the prospective relation between ineffectiveness and binge eating was mediated by dieting or thinness expectancies, as was the prospective relation between ineffectiveness and purging. This application of a basic science theory to eating disorder risk appears fruitful, and the findings suggest the importance of early interventions that address both disposition and learning.

Abstract
OBJECTIVE To ascertain whether women with eating disorders have a higher frequency of separation anxiety symptoms in childhood, and a higher prevalence of insecure styles of adult attachment, compared with healthy women. METHODS The Separation Anxiety Symptom Inventory (SASI) and the Attachment Style Questionnaire (ASQ) were administered to 78 women with eating disorders and 64 healthy women. RESULTS Compared with control women, women with eating disorders reported more severe symptoms of separation anxiety during childhood, and scored higher on the ASQ scales, reflecting insecure styles of adult attachment. Early separation anxiety and insecure attachment were not correlated with age of onset or illness duration. The diagnostic subgroup was not associated with a specific style of insecure attachment: compared with control women, both anorexic and bulimic women scored higher on the ASQ scales reflecting anxious attachment, but not on the scales reflecting avoidant attachment. CONCLUSIONS The results confirm the link between eating disorders and insecure attachment that has been found in previous studies, and extend it to childhood symptoms of separation anxiety.

Abstract
OBJECTIVE This study examined perfectionism in relation to recovery from eating disorders by comparing different conceptualizations of perfectionism across healthy controls and fully recovered, partially recovered, and active eating disorder cases, where full recovery was defined using physical, behavioral, and psychological indices. METHOD Participants were primarily young adult females; 53 active eating disorder cases, 15 partially recovered cases, 20 fully recovered cases, and 67 healthy controls. Participants completed questionnaires assessing trait perfectionism, perfectionistic self-presentation style, and frequency of perfectionism cognitions, as well as a diagnostic interview to determine lifetime and current eating disorder diagnoses. RESULTS A robust pattern emerged whereby the fully recovered individuals and healthy controls had similar levels of perfectionism that were significantly lower than the perfectionism levels of the partially recovered and active individuals with eating disorder, who were comparable to each other. DISCUSSION These findings have implications for more clearly defining eating disorder recovery and for the role perfectionism may play in achieving full recovery.

Abstract
The assessment of personality and temperament in the context of eating disorders (EDs) poses unique challenges because of the physiological symptoms and sequelae of these illnesses. Four models of the relationship between personality and EDs are presented, along with a discussion of the different methodological designs which can evaluate these models. Current data support the likelihood that neuroticism and perfectionism are risk factors for EDs. Perfectionism and the related obsessive-compulsive personality disorder may also share a common cause with anorexia nervosa. High harm avoidance and low self-directedness also characterize all EDs, though more data are needed to confirm their role as risk factors; importantly however, this combination of traits may diminish one's ability to cope with stressful life events. At the other end of the spectrum, considering impulsivity multidimensionally may be important to understanding the role of this personality trait in EDs, though existing data do not yet allow for conclusions regarding its role as a risk factor versus a consequence of the ED. All of the identified traits that may be risk factors are also exacerbated as a consequence of having, or having had, an ED. Finally, the role of personality disorders in influencing the course and outcome of EDs is still unclear. A fruitful avenue for future research in this area is to utilize personality and temperament to classify individuals in a way that allows for the best chance of identifying genetic loci that confer increased risk for EDs.

Abstract
OBJECTIVE The purpose of this investigation was to examine differences in personality dimensions among individuals with bulimia nervosa, binge eating disorder, non-binge eating obesity, and a normal-weight comparison group as well as to determine the extent to which these differences were independent of self-reported depressive symptoms. METHOD Personality dimensions were assessed using the Multidimensional Personality Questionnaire in 36 patients with bulimia nervosa, 54 patients with binge eating disorder, 30 obese individuals who did not binge eat, and 77 normal-weight comparison participants. RESULTS Participants with bulimia nervosa reported higher scores on measures of stress reaction and negative emotionality compared to the other 3 groups and lower well-being scores compared to the normal-weight comparison and the obese samples. Patients with binge eating disorder scored lower on well-being and higher on harm avoidance than the normal-weight comparison group. In addition, the bulimia nervosa and binge eating disorder groups scored lower than the normal-weight group on positive emotionality. When personality dimensions were reanalyzed using depression as a covariate, only stress reaction remained higher in the bulimia nervosa group compared to the other 3 groups and harm avoidance remained higher in the binge eating disorder than the normal-weight comparison group. CONCLUSIONS The higher levels of stress reaction in the bulimia nervosa sample and harm avoidance in the binge eating disorder sample after controlling for depression indicate that these personality dimensions are potentially important in the etiology, maintenance, and treatment of these eating disorders. Although the extent to which observed group differences in well-being, positive emotionality, and negative emotionality reflect personality traits, mood disorders, or both, is unclear, these features clearly warrant further examination in understanding and treating bulimia nervosa and binge eating disorder.

Abstract
OBJECTIVE: The main aims of this article are twofold. First, to assess perfectionism dimensions in obsessive-compulsive disorder and eating disorders in comparison with psychiatric control (depression/anxiety) and non-clinical control groups. Second, to examine if perfectionism is specifically related to these different clinical conditions. METHOD: Thirty-nine outpatients with obsessive-compulsive disorder, 24 outpatients with eating disorders, 65 outpatients with a diagnosis of depression and/or anxiety, and 70 non-clinical participants completed the Portuguese version of the Multidimensional Perfectionism Scale. RESULTS: Compared to non-clinical subjects, individuals of all clinical samples had significantly higher scores on Multidimensional Perfectionism Scale total score, Self-Oriented and Socially-Prescribed Perfectionism. There were no significantly differences in Self-Oriented Perfectionism and Multidimensional Perfectionism Scale total score in all the three clinical samples. Subjects from the eating disorders sample had significantly higher scores of Socially-Prescribed Perfectionism in comparison to obsessive-compulsive disorder and psychiatric control samples. CONCLUSION: Perfectionism showed to be related with this broad range of psychopathologies. However, the differences between eating disorders versus obsessive-compulsive disorder and psychiatric control on Socially-Prescribed Perfectionism warrant further investigation in order to clarify the specificity of this perfectionism dimension in eating disorders.

Abstract
OBJECTIVE To identify factors influencing the course of anorexia nervosa (AN) over time. METHOD Former female patients with AN (36 remitted and 24 nonremitted) and 31 healthy females responded to standardized interviews and self-rating questionnaires. Remitted patients maintained normal eating, normal weight, and regular menses for the past 12 months. Patients not fulfilling these criteria were considered nonremitted. RESULTS Using logistic regression, we identified that number of hospitalizations, duration of ambulatory treatment, past vegetarianism, past anxiety, and childhood sexual abuse differentiated remitted from nonremitted patients, predicting nonremission. A similar analysis identified that elevated follow-up vegetarianism and eating-related concerns and lower body mass index (BMI) differentiated remitted from nonremitted patients, contributing to nonremission. Univariate analyses identified that remitted patients had elevated anxiety and eating-related obsessionality compared with the controls, suggesting these variables to potentially predispose to AN. DISCUSSION Elevated anxiety and eating-related obsessionality may increase the risk for the development of AN and for nonremission.

Clin Psychol Rev 2008; 28:1413-25.

Abstract
Recent advances in personality theory indicate that there are distinct constructs that dispose individuals to rash action and risky behavior, as opposed to one broad trait of impulsivity. Two are emotion based, two represent deficits in conscientiousness, and one is sensation seeking. Previous studies of impulsivity and its relationship to bulimia nervosa have yielded mixed findings. The authors applied this advance in personality theory to the study of bulimia nervosa (BN) to test the hypothesis that the emotion-based disposition of negative urgency (the tendency to act rashly when distressed) relates most strongly to BN symptoms. A meta-analysis of 50 articles indicated the following. Negative urgency had by far the largest effect size (weighted r=.38), followed by sensation seeking (weighted r=.16); lack of planning (weighted r=.16) and lack of persistence (weighted r=.08). Methodological moderators of the effect of distinct traits on BN symptoms were the use of scales that precisely measured one construct as opposed to general impulsivity scales that measured several constructs, clinical vs. non-clinical samples, and whether or not the personality scale was translated from its original language or not. Negative urgency appears especially important for BN; more broadly, researchers should consider the role of emotion-based dispositions to rash acts in their risk theories.

Abstract
The literature examining the relation between perfectionism and eating disorders was reviewed and content and methodological comparisons were made with the perfectionism literature in anxiety disorders and depressive disorders. A PsychInfo search using the key words "perfectionism/perfect/perfectionistic," "anorexia," "bulimia," and "eating disorders" was performed and the generated list of papers was supplemented based on a review of reference lists in the papers. A total of 55 papers published between 1990 and 2005 were identified that assessed perfectionism among individuals with diagnosed eating disorders. The key research questions were distilled from these publications and empirical findings were summarized for each question, followed by a comparison with perfectionism papers in the anxiety and depressive disorder literatures. Also, key research design methodological parameters were identified and comparisons made across the three literatures: eating disorders, anxiety disorders, depressive disorders. The current review concludes with conceptual and methodological recommendations for researchers interested in perfectionism and eating disorders.

Abstract
Bulimia nervosa is a disorder of complex etiology that tends to occur in young women. These individuals binge eat and purge by vomiting or other means, and often have depression, anxiety, substance abuse and extremes of impulse control. It is thought that binge eating and purging behaviors are, at least in part, a means of coping with dysphoric mood states and interpersonal stress. Bulimic symptoms are not likely to abate without development of new coping skills and behaviors. In the past 25 years, considerable progress has been made in developing specific psychotherapies and medication for the treatment of bulimia nervosa. Despite this progress, many individuals have partial responses to therapy and may remain chronically ill. This complex illness often requires a multidisciplinary team of professionals for effective management and, despite significant advances in treatment, bulimia nervosa continues to present major challenges for providers of care.

Abstract
OBJECTIVES The main objective was to explore which are the dimensions of perfectionism that are linked to disordered eating behaviour (EB) in a large non-clinical sample of both genders. METHOD One thousand one hundred and sixty-three undergraduate students of the University of Coimbra completed the Portuguese versions of the multidimensional perfectionism scale (MPS) and the eating attitudes test (EAT-40). RESULTS In both genders, the MPS total score was associated with the EAT total score and all EAT dimensions (except for socially prescribed perfectionism in females). Self-oriented perfectionism (SOP) and socially prescribed perfectionism (SPP) were associated with EAT total score, diet concerns (DC) and bulimic behaviour (BB) in females while in males the social prescribed perfectionism (SPP) was the useful predictor of EAT total score, BB and social pressure to eat (SPE). CONCLUSION These results confirm that in general high levels of perfectionism are associated with abnormal EB. This was the case for both genders for SPP but for SOP for females only. The association for other oriented perfectionism (OOP) was greater for males than for females.

Abstract
OBJECTIVE There is a paucity of research examining eating disorder symptoms among middle-aged women. METHOD This prospective study assessed the stability of bulimic symptoms and 5 associated variables (perfectionism, depressive symptoms, self-esteem, anxiety symptoms, and perceived weight status) in a sample of 150 middle-aged women (mean age = 45.19 years) over a 2.5-year time period. In addition, interrelations among bulimic, anxiety, and depressive symptoms were assessed. RESULTS Results suggested that all 6 bulimia-related variables remained significantly stable over 2.5 years. In addition, notable relations between Time 1 and Time 2 variables emerged (e.g., anxious symptoms at Time 1 predicted bulimic symptoms at Time 2). CONCLUSION Thus, the results indicate that bulimic symptoms exist in middle-aged women, and that they remain relatively stable over a 2.5-year time period. Clinical implications for middle-aged women with eating disorder symptoms are discussed.

Abstract
Methodological approaches utilized to evaluate models of the relationship between personality and eating disorders, as well as empirical support for each model, are reviewed. Limited prospective research suggests that negative emotionality, perfectionism, drive for thinness, poor interoceptive awareness, ineffectiveness, and obsessive-compulsive personality traits are likely predisposing factors. Limited family study research suggests that obsessive-compulsive personality disorder (OCPD) and anorexia nervosa share a common familial liability. Potential pathoplastic personality factors include Cluster B personality disorders and OCPD, which predict a poorer course and/or outcome, and histrionic personality traits and self-directedness, which predict a more favorable course and/or outcome. Future research should focus upon sophisticated prospective and family study research in order to best evaluate competing models of the eating disorder-personality relationship.

Abstract
OBJECTIVE We compared individuals recovered from anorexia (AN) and bulimia nervosa (BN) to determine characteristics that are shared by or distinguish eating disorder (ED) subtypes. METHOD Sixty women recovered for > or = 1 year from AN or BN were compared with 47 control women (CW). Assessments included the Yale-Brown-Cornell Eating Disorder Scale, the Spielberger State-Trait Anxiety Inventory, the Beck Depression Inventory, the Yale-Brown Obsessive Compulsive Scale, the Temperament and Character Inventory, and Structured Clinical Interviews for DSM-IV. RESULTS Individuals recovered from an ED had similar scores for mood and personality variables that were significantly higher than the scores for CW. Few recovered subjects had Cluster B personality disorder. Most individuals recovered within 6 years of their ED onset. A latent profile analysis identified an "inhibited" and "disinhibited" cluster based on personality traits. CONCLUSION A wide range of symptoms persist after recovery and do not differ between subtypes of ED. These findings may aid in identifying traits that create vulnerabilities for developing an ED.

Abstract
A specific model for eating disorder symptoms involving perfectionistic self-presentation and two different moderators (i.e., body image evaluation and body image investment) was tested. Participants completed measures of perfectionistic self-presentation, body image dysfunction, and eating disorder symptoms. Findings indicated that all three dimensions of perfectionistic self-presentation were associated with eating disorder symptoms. Results also showed that perfectionistic self-presentation predicted eating disorder symptoms in women who were dissatisfied with their bodies, but that it did not predict eating problems in women who liked their bodies and felt there was little or no discrepancy between their actual and ideal appearances. Body image investment did not moderate the relationship between perfectionistic self-presentation and eating disorder symptoms, suggesting that ego-involvement alone is insufficient to promote eating disturbance in the context of perfectionism. The importance of self-presentation components of perfectionism and specific body image difficulties in predicting eating disorder symptoms are discussed.

Abstract
Anorexia nervosa (AN) and bulimia nervosa (BN) are disorders of eating and weight-related behavior that together afflict some 1-3% of women in the United States. One of the remarkable features about each of the eating disorders is how persistent the disordered eating behavior becomes once it has begun. Substantial psychological, social, and physiological disturbances are associated with eating disorders, and it has been very difficult to disentangle those factors that may result from the disturbed behavior from the factors that may have predisposed individuals to, or precipitated the development of, the disorder. This article will briefly review the definitions, phenomenology, and identified risk factors for development of each of the major eating disorders. Pathophysiology will be discussed, with a particular focus on candidate factors that might sustain disordered eating behavior, as informed by clinical and basic science research. Future research directions will be suggested.

Abstract
OBJECTIVES To determine the effects of sex, perfectionism, level of athletic participation (varsity vs. recreational), and type of sport (swimming, running, or soccer) on disordered eating. METHOD Male and female swimmers, runners, and soccer players at Stanford University were recruited at both the recreational and varsity level. Athletes were given the Multidimensional Perfectionism Scale (MPS), the Eating Attitudes Test-26 (EAT-26), the Eating Disorders Examination Questionnaire (EDE-Q), and a survey on demographics and level of athletic competition. Of 257 athletes identified, 250 (97.3%) returned the questionnaires. RESULTS A Multivariate Analysis of Variance (MANOVA) was used to assess the variables' effects on disordered eating attitudes. Significant main effects were found for Sex (F5,199=25.7, p<0.001), Level (F5,199=2.5, p<0.05), and Perfectionism (F10,400=3.0, p<0.001). Only two of the ten interaction terms were significant: Sex by Level of athletic participation (F5,199=3.2, p<0.01) and Sex by Perfectionism (F10,400=2.1, p<0.05). Females displayed higher disordered eating than males. Disordered eating attitudes increased with perfectionism and were greater for recreational athletes than varsity, but this trend was significant for females only. Type of sport showed no significant effects. When examining physiological data a higher percentage of varsity females had irregular periods (42.9%) or amenorrhea (14.3%) than recreational females (13.4% and 2.9%, respectively). DISCUSSION Males showed little variability in their data due to low disordered eating scores overall, thus demonstrated few significant results. The greatest risk factor for disordered eating attitudes for females was perfectionism, which crossed all athletic divisions. Although recreational athletes seemed more at risk psychologically, the varsity athletes had more physiological risk.

Abstract
OBJECTIVE Twin and family studies suggest that genetic variants contribute to the pathogenesis of bulimia nervosa (BN) and anorexia nervosa (AN). The Price Foundation has supported an international, multisite study of families with these disorders to identify these genetic variations. The current study presents the clinical characteristics of this sample as well as a description of the study methodology. METHOD All probands met modified criteria for BN or bulimia nervosa with a history of AN (BAN) as defined in the 4th ed. of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994). All affected relatives met DSM-IV criteria for BN, AN, BAN, or eating disorders not otherwise specified (EDNOS). Probands and affected relatives were assessed diagnostically using both trained-rater and self-report assessments. DNA samples were collected from probands, affected relatives, and available biologic parents. RESULTS Assessments were obtained from 163 BN probands and 165 BAN probands. Overall, there were 365 relative pairs available for linkage analysis. Of the affected relatives of BN probands, 62 were diagnosed as BN (34.8%), 49 as BAN (27.5%), 35 as AN (19.7%), and 32 as EDNOS (18.0%). For the relatives of BAN probands, 42 were diagnosed as BN (22.5%), 67 as BAN (35.8%), 48 as AN (25.7%), and 30 as EDNOS (16.0%). DISCUSSION This study represents the largest genetic study of eating disorders to date. Clinical data indicate that although there are a large number of individuals with BN disorders, a range of eating pathology is represented in the sample, allowing for the examination of several different phenotypes in molecular genetic analyses.
