Almaghrbi H, Bawadi H. Genetic polymorphisms and their association with neurobiological and psychological factors in anorexia nervosa: a systematic review. Front Psychol 2024; 15:1386233. [PMID: 38979077 PMCID: PMC11229080 DOI: 10.3389/fpsyg.2024.1386233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2024] [Accepted: 04/29/2024] [Indexed: 07/10/2024] Open
Abstract
Background and aims Anorexia nervosa (AN) is a complex neuropsychiatric disorder. This systematic review synthesizes evidence from diverse studies to assess and investigate the association between gene polymorphisms and psychological and neurobiological factors in patients with AN. Methods A systematic search across PubMed, PsycINFO, Scopus, and Web of Science databases, along with manual searching, was conducted. The review protocol was approved by PROSPERO (CRD42023452548). Out of 1,250 articles, 11 met the inclusion criteria. The quality of eligible articles was assessed using the Newcastle-Ottawa Scale (NOS) tool. The systematic review followed the PRISMA guidelines. Results The serotoninergic system, particularly the 5-HTTLPR polymorphism, is consistently linked to altered connectivity in the ventral attention network, impaired inhibitory control, and increased susceptibility to AN. The 5-HTTLPR polymorphism affects reward processing, motivation, reasoning, working memory, inhibition, and outcome prediction in patients with AN. The dopaminergic system, involving genes like COMT, DRD2, DRD3, and DAT1, regulates reward, motivation, and decision-making. Genetic variations in these dopaminergic genes are associated with psychological manifestations and clinical severity in patients with AN. Across populations, the Val66Met polymorphism in the BDNF gene influences personality traits, eating behaviors, and emotional responses. Genes like OXTR, TFAP2B, and KCTD15 are linked to social cognition, emotional processing, body image concerns, and personality dimensions in patients with AN. Conclusion There was an association linking multiple genes to the susceptibly and/or severity of AN. This genetic factor contributes to the complexity of AN and leads to higher diversity of its clinical presentation. Therefore, conducting more extensive research to elucidate the underlying mechanisms of anorexia nervosa pathology is imperative for advancing our understanding and potentially developing targeted therapeutic interventions for the disorder.Systematic review registration: [https://clinicaltrials.gov/], identifier [CRD42023452548].

Similarities and differences between eating disorders and obsessive-compulsive disorder in childhood and adolescence: a systematic review. Front Psychiatry 2024; 15:1407872. [PMID: 38895032 PMCID: PMC11183500 DOI: 10.3389/fpsyt.2024.1407872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Accepted: 05/21/2024] [Indexed: 06/21/2024] Open
Abstract
Background The developmental age, comprising childhood and adolescence, constitutes an extremely important phase of neurodevelopment during which various psychiatric disorders can emerge. Obsessive-Compulsive Disorder (OCD) and Eating Disorders (ED) often manifest during this critical developmental period sharing similarities but also differences in psychopathology, neurobiology, and etiopathogenesis. The aim of this study is to focus on clinical, genetic and neurobiological similarities and differences in OCD and ED. Methods This study is based on a PubMed/MEDLINE and Cochrane Central Register for Controlled Trial (CENTRAL). The research adhered to the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Results The aforementioned search yielded an initial collection of 335 articles, published from 1968 to September 2023. Through the application of inclusion and exclusion criteria, a total of 324 articles were excluded, culminating in a final selection of 10 articles. Conclusions Our findings showed both differences and similarities between OCD and ED. Obsessive-compulsive (OC) symptoms are more prevalent in ED characterized by a binge/purge profile than in those with a restrictive profile during developmental age. OC symptomatology appears to be a common dimension in both OCD and ED. When presents, OC symptomatology, exhibits transversal characteristic alterations in the anterior cingulate cortex and poorer cognitive flexibility. These correlations could be highlighted by genetic overlaps between disorders. A comprehensive definition, integrating psychopathological and neurobiological aspects could significantly aid treatment selection and thereby influence the prognosis of these patients.

Abstract
Orthorexia nervosa (ON) refers to a pathological obsession with healthy eating characterized by a restrictive diet, ritualized eating patterns, and strict avoidance of foods believed to be unhealthy or unclean. On the other hand, healthy orthorexia (HO) is defined as an interest in healthy eating and a tendency to eat healthy foods. This study aimed to investigate the relationships between the ON, HO, maternal rejection, perfectionism, self-critical rumination, and body attitude in the women sample. 445 female students from diverse universities in Turkey was attended to our study. Participants completed questionnaires regarding ON and HO, body attitude, maternal rejection, perfectionism, and self-critical rumination. The results showed that negative body attitudes could not predict both HO (B=-.008, SE=.039, p=.791) and ON (B=.008, SE=.032, p=.835). However, perfectionism and self-critical rumination had mediator roles in the relationship between ON and HO with maternal rejection, despite this relationship was positive for ON (B = .014, Boot SE = .007, 95% Boot CI [.003, .029]), but negative for HO (B = -.023, Boot SE = .010, 95% Boot CI [-.042, -.008]). Not a negative body attitude, but maternal rejection, perfectionism, and self-critical rumination played roles in developing orthorexic tendencies.

Self-hate, dissociation, and suicidal behavior in bulimia nervosa. J Affect Disord 2023; 335:44-48. [PMID: 37178824 DOI: 10.1016/j.jad.2023.05.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 03/27/2023] [Accepted: 05/06/2023] [Indexed: 05/15/2023]
Abstract
BACKGROUND Individuals with eating disorders (EDs) often struggle with markedly low self- esteem and are at risk for suicidal behavior. Dissociation and perceived burdensomeness are often cited as facilitators of suicidal outcomes. Specifically, perceived burdensomeness is comprised of self-hate and liability on others, although it remains unclear which variables most heavily influence suicidal behavior in EDs. METHODS In a sample of 204 women with bulimia nervosa, the present study examined the potential impact of self-hate and dissociation on suicidal behavior. We hypothesized that suicidal behavior would be equally, and potentially more strongly, related to self-hate than dissociation. Regression analyses investigated the unique effects of these variables on suicidal behavior. RESULTS Consistent with our hypothesis, a significant relationship emerged between self-hate and suicidal behavior (B = 0.262, SE = 0.081, p < .001, CIs = 0.035-0.110, R-squared =0.07) but not between dissociation and suicidal behavior (B = 0.010, SE = 0.007, p = .165, CIs = -0.389-2.26, R-squared =0.010). Additionally, when controlling for one another, both self-hate (B = 0.889, SE = 0.246, p < .001, CIs = 0.403-1.37) and capability for suicide (B = 0.233, SE = 0.080, p = .004, CIs = 0.076-0.391) were uniquely and independently associated with suicidal behavior. LIMITATIONS Future work should include longitudinal analyses to understand temporal relationships among study variables. CONCLUSIONS In sum, when considering suicidal outcomes, these findings support a view that highlights personal loathing rooted in self-hate rather than de-personalizing aspects of dissociation. Accordingly, self-hate may emerge as a particularly valuable target for treatment and suicide prevention in EDs.

The indirect role of orthorexia nervosa and eating attitudes in the association between perfectionism and muscle dysmorphic disorder in Lebanese male University students - results of a pilot study. BMC Psychiatry 2023; 23:55. [PMID: 36670380 PMCID: PMC9854036 DOI: 10.1186/s12888-023-04549-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Accepted: 01/16/2023] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND The literature highly concentrates on disorders related to body image among women but only minimally when it comes to the male population; hence, in order to provide general practitioners, and primary care physicians in general, and psychiatrists in particular, with additional information concerning muscle dysmorphia among male university students in Lebanon, this study seemed essential, and was therefore conducted to (1) identify the prevalence of MDD, and (2) evaluate the indirect effect of eating attitudes in general and orthorexia nervosa in particular, in the association between perfectionism and muscle dysmorphic disorder (MDD) among a sample of male university students. METHODS In this cross-sectional study conducted between September 2021 and May 2022, 396 male university students from multiple universities in Lebanon filled the online Arabic questionnaire. RESULTS The results showed that 26 (6.6%) of the participants had MDD. Orthorexia nervosa and eating attitudes mediated the association between perfectionism and MDD; higher perfectionism was significantly associated with higher ON and more inappropriate eating; higher ON and more inappropriate eating were significantly associated with higher MDD, whereas perfectionism had a significant total direct effect on MDD. The high prevalence of MDD among male university students in Lebanon implies further investigation on the national level in the country. CONCLUSION Awareness campaigns among the university students could be adopted at the national level to increase the level of knowledge on the concepts of obsessive self-destructive perfectionism, orthorexia nervosa and muscle dysmorphia.

Abstract
UNLABELLED Eating disorders (ED) are severe mental disorders that may result in significant functional impairment and disability. Neuropsychological studies have consistently found impaired executive function (EF) among ED patients. EF is particularly involved in fundamental skills of daily living and in behavioral and emotional regulation. In this study, impairment of executive functioning is investigated in patients with eating disorders and the associations with clinical features and clinical subtypes are analyzed. METHOD 75 female patients (m = 22.01 years, sd = 9.15) with eating disorder (43 restrictive anorexia, 30 binge-eating anorexia and 13 bulimia nervosa) and 37 healthy controls (m = 18.54 years, sd = 4.21) were included in the study. An extensive assessment of executive function domains (verbal fluency, set shifting, attention span, selective attention, working memory, inhibitory control and processing speed) was carried out in both groups. Clinical scales for food intake restriction, binge-eating/purging, depression, anxiety and impulsivity were also administered and correlated with scores on executive function tests. RESULTS Patients with an ED had significantly lower scores than healthy controls in performance of several executive function tests, particularly in set shifting, interference control and processing speed (p < .01, in all three domains). Executive function impairment was related to anxious, depressive and eating disorder symptoms (p < .05), regardless of clinical subtype. CONCLUSIONS Executive function impairment in eating disorders is associated with greater ED symptomatic severity and might involve a negative treatment outcome. Therefore, cognitive remediation techniques should probably be considered in a number of severe patients with ED.

Interactional Effects of Multidimensional Perfectionism and Cognitive Emotion Regulation Strategies on Eating Disorder Symptoms in Female College Students. Brain Sci 2021; 11:brainsci11111374.

Abstract
Given the inconclusive findings regarding the relation between perfectionism and eating disorder symptoms, it is important that we determine whether this relation is modulated by emotion dysregulation, which is a prominent risk factor for eating disorders. We sought to identify specific cognitive emotion regulatory strategies—rumination, self-blame, and catastrophizing—that interact with multidimensional perfectionism to shape eating disorder symptoms (i.e., shape, weight, eating concerns, and dietary restraint). Using latent moderated structural equation modeling, we analyzed data from 167 healthy young female adults. We found that only rumination significantly moderated the relation between socially prescribed perfectionism and eating disorder symptoms. However, this was not observed for self-oriented perfectionism or other regulatory strategies. These findings held true when a host of covariates were controlled for. Our findings underscore the crucial role of rumination, a modifiable emotion regulatory strategy, in augmenting the relation between socially prescribed perfectionism and eating disorder symptoms in young women.

Abstract
Eating disorders (ED) are considered as heterogeneous disorders with a complex multifactor etiology that involves biological and environmental interaction. Objective: The aim was to identify specific ED bio-psychological-familial correlates at illness onset. Methods: A case-control (1:1) design was applied, which studied 50 adolescents diagnosed with ED at onset (12-17 years old) and their families, paired by age and parents' socio-educational level with three control samples (40 with an affective disorder, 40 with asthma, and 50 with no pathology) and their respective families. Biological, psychological, and familial correlates were assessed using interviews, standardized questionnaires, and a blood test. Results: After performing conditional logistic regression models for each type of variable, those correlates that showed to be specific for ED were included in a global exploratory model (R 2 = 0.44). The specific correlates identified associated to the onset of an ED were triiodothyronine (T3) as the main specific biological correlate; patients' drive for thinness, perfectionism and anxiety as the main psychological correlates; and fathers' emotional over-involvement and depression, and mothers' anxiety as the main familial correlates. Conclusion: To our knowledge, this is the first study to use three specific control groups assessed through standardized interviews, and to collect a wide variety of data at the illness onset. This study design has allowed to explore which correlates, among those measured, were specific to EDs; finding that perfectionism and family emotional over-involvement, as well as the T3 hormone were relevant to discern ED cases at the illness onset from other adolescents with or without a concurrent pathology.

Abstract
The clinical significance of two major aspects of perfectionism, perfectionistic strivings (PS) and perfectionistic concerns (PC), in eating disorders (EDs) symptoms was well-established among adults. However, no systematic review has assessed evidence examining associations between both unidimensional and multidimensional perfectionism and EDs in early and middle adolescence. For this aim, three online databases (PsycINFO, Medline and PsycArticle) were searched for articles published until January 2019, and observational studies were considered. Study quality was systematically appraised, and results were summarized using a narrative synthesis approach. Fifty-one cross-sectional and 28 longitudinal studies were included. Most studies supported the relationship between perfectionism and EDs, with the majority adopting a unidimensional approach for assessing perfectionism. Among studies that employed multidimensional measures of perfectionism, the majority (n = 11) of evidence supported the relationship between eating symptoms and PC, while fewer (n = 5) studies provided significant unique associations with PS. These findings are consistent with the body of research suggesting the strength of the relationship between PC and EDs was greater than between PS and EDs. It was recommended that preventive interventions should be primarily focused on reducing self-critical perfectionism, since it resulted to be the most relevant perfectionistic dimension in the development of eating symptoms in adolescents.

Abstract
OBJECTIVE This study examined the associations between parent-oriented dimensions of perfectionism (parental expectations [PE] and parental criticism [PC]) and eating disorder (ED) symptomatology across racial/ethnic groups. It was hypothesized that parent-oriented perfectionism would be positively associated with ED symptomatology for White and Asian American women. METHOD Undergraduate women (N = 1,173) completed questionnaires assessing perfectionism, EDs, and demographics. One-way analyses of variance tested differences in PE and PC across racial/ethnic groups; post-hoc Tukey tests probed significant differences. Multiple linear regressions assessed associations between parent-oriented perfectionism and ED symptomatology. Hurdle models tested the association between PE and PC and the frequency and odds of endorsing ED symptomatology. RESULTS There were significant group differences in PE and PC. PE was positively linked with various ED symptoms in Latina, Asian American, and multiracial women, and was negatively related to purging in multiracial women. PC was positively associated with body dissatisfaction in White, Black, and multiracial women, but displayed differential associations with ED symptomatology in all racial/ethnic groups. DISCUSSION Levels of parent-oriented dimensions of perfectionism, and their relations to ED symptomatology, might vary across racial/ethnic groups. PE, in particular, is both more elevated, and more strongly linked to eating pathology in Asian American women, whereas PC appears to be especially relevant to ED symptoms in Black women. Findings underscore the importance of considering the role of culture in ED symptomatology. Clinicians and researchers might consider incorporating assessments of parent-oriented perfectionism into their practice.

Abstract
This research investigated associations between socially prescribed and self-orientated perfectionism, and the social functioning of 510 preteens (Mage = 11.2). The study focused on predictions from the Perfectionism Social Disconnection Model (PSDM) by determining whether rejection sensitivity and social isolation, in that sequence, mediated the associations between both perfectionism types and mental health outcomes. Employing both survey and experimental methods, findings indicated that both types of perfectionism in preadolescence were associated with increased interpersonal difficulty, rejection sensitivity and feelings of social isolation, as well as higher levels of eating disorder symptoms, depression, and anxiety. Results from serial mediation analyses found general support for the theoretical predictions of the PSDM for socially prescribed perfectionism, and extending upon previous research, for self-orientated perfectionism. The age of the sample suggests that both forms of perfectionism may be important targets in programs to prevent the development of mental health problems.

Abstract
The current study tested the hypothesis that perfectionism is a risk factor for the development of body dysmorphic disorder (BDD), as proposed by prevailing cognitive behavioural models. School students aged 14-16 years completed questionnaires 6 months apart (Time 1: N = 302; Time 2: N = 68) assessing perfectionism, BDD symptoms, and anxiety and depression. Robust regression models tested concurrent and prospective associations between perfectionism and BDD symptoms, with and without adjustment for coexisting anxiety and depression. Total perfectionism was positively associated with concurrent BDD symptoms, even when controlling for coexisting anxiety and depression. Moreover, total perfectionism predicted changes in BDD symptoms between Time 1 and Time 2. Examination of perfectionism subscales indicated that only self-oriented perfectionism, not socially-prescribed perfectionism, predicted BDD symptoms concurrently and prospectively while controlling for coexisting psychopathology. This study provides preliminary evidence for self-oriented perfectionism being a risk factor for the development of BDD in youth. If replicated, these findings could highlight the potential value of targeting self-oriented perfectionism in prevention and early intervention programs for BDD.

Abstract
OBJECTIVE Despite the multitude of research surrounding anorexia nervosa (AN) and perfectionism, there is yet to be a thorough investigation comparing perfectionism in those diagnosed with AN and other eating disorders, and other psychiatric diagnoses. The current meta-analysis aimed to explore these comparisons. METHOD Following the Preferred Reporting Items or Systematic Reviews Meta Analyses (PRISMA) guidelines, we identified empirical studies that compared maladaptive and/or adaptive perfectionism scores in those diagnosed with AN and either a non-clinical comparison group, people diagnosed with a non-AN ED, or people diagnosed with another psychological disorder (i.e., other DSM diagnoses). In total, we identified 23 studies, comprising 3,561 participants who were all female. Comparison groups extracted from the studies were a non-clinical group, bulimia nervosa (BN) diagnosis group, and another psychological diagnostic group. RESULTS When AN maladaptive perfectionism levels were compared against the comparison groups, the results showed that those diagnosed with AN were more perfectionistic compared to the non-clinical group (g = 1.00), and the other psychiatric diagnosis group (g = 0.41). People diagnosed with AN also had higher levels of adaptive perfectionism levels compared to the non-clinical group (g = 1.24). Comparisons between those diagnosed with AN and BN were statistically non-significant for maladaptive perfectionism. DISCUSSION Although publication bias potentially affected the psychological diagnosis group comparisons, findings suggest that maladaptive perfectionism is a factor associated with both AN and BN.

Abstract
The 2 × 2 model of dispositional perfectionism has been very well received by researchers of the topic, leading to the creation of new studies that have analyzed the way in which the four proposed subtypes are distinctly associated with measures of adaptation and maladjustment. The goal of this study was to determine the possible existence of four profiles of child perfectionism that are congruent with the subtypes proposed by the 2 × 2 model, and whether these subtypes are associated with school anxiety, in accordance with the hypotheses established by the model. The sample was composed of 2157 students from Spanish Primary Education aged between 8 and 11 years (M = 9.60, SD = 1.24). The Child and Adolescent Perfectionism Scale was used to assess Socially Prescribed Perfectionism and Self-Oriented Perfectionism, and the School Anxiety Inventory for Primary Education was used to measure school anxiety. The results of cluster analysis identified four differential groups of perfectionists similar to the subtypes defined by the 2 × 2 model: Non-Perfectionism, Pure Personal Standards Perfectionism (Pure PSP), Pure Evaluative Concerns Perfectionism (Pure ECP), and Mixed Perfectionism. The four groups presented a differentiable pattern of association with school anxiety, with the exception of Pure PSP and Pure ECP, which showed no significant differences. Participants classified as Non-perfectionists presented the most adaptive outcomes, whereas subjects included in the Mixed Perfectionism group scored significantly higher on school anxiety than the three remaining groups. To conclude, the results partially supported the hypotheses of the 2 × 2 model, questioning the consideration of Self-Oriented Perfectionism as a positive manifestation of perfectionism and showing that it is the combination of high scores in both perfectionist dimensions, Self-Oriented Perfectionism and Socially Prescribed Perfectionism that implies higher levels of school anxiety. These findings should be taken into account when generalizing the 2 × 2 model to child population.

Abstract
This study examined the mediating role of self-oriented and socially prescribed perfectionism in the relationship between sociocultural influences (i.e., media, peer, and teasing) and symptoms of muscle dysmorphia (MD) and eating disorders (ED). A nonclinical sample of males (N = 158, Mage = 26.94, SD = 5.50) completed measures of perfectionism, MD, body dissatisfaction, drive for thinness, and bulimia. Susceptibility to appearance-based messages from the media, their peers, and family was also measured. Analyses confirmed the partial mediating role of self-oriented perfectionism only for drive for thinness. In contrast, socially prescribed perfectionism was found to be a partial mediator between all three sociocultural variables and measures of both MD and ED; except for those between peer influence and body dissatisfaction, and teasing and bulimia symptomatology. These two relationships were fully mediated by socially prescribed perfectionism. Results suggest that vulnerability to MD and ED depend on pre-existing perfectionistic attitudes, particularly that of socially prescribed perfectionism.

Abstract
This pilot study examined the effects of perfectionism on blood pressure (BP) in response to repeated exposure to mental arithmetic stressors. College students (N = 30) in a laboratory setting were administered a series of challenging mathematical tasks. BP was measured at baseline and after each task. Multilevel modelling analyses revealed that BP tended to decline over the course of the mathematical tasks. However, higher levels of performance standards predicted relatively stable levels of systolic BP, whereas moderate and lower levels of standards predicted declines in systolic BP. Higher levels of self-critical perfectionism predicted generally sustained levels of diastolic BP, with moderate and low self-criticism predicting declines in diastolic BP during the repeated stressors. These preliminary results suggest that students with higher levels of perfectionism may be at risk for physiological problems associated with stress reactivity, perhaps especially so in situations in which they experience persistent stress. Although results were qualified by a relatively small sample size, effects were statistically significant and supported the importance of examining the short-term and long-term implications of the effects of perfectionism on cardiovascular function and the different implications of elevations in systolic and diastolic BP.

Abstract
OBJECTIVE Eating disorders are an increasingly prevalent health problem among adolescent girls. It is well known that biological, psychosocial, and family-related factors interact in the development of this group of disorders. However, the mechanisms underlying the interaction between these variables are still poorly understood, especially in Portuguese adolescents. The aim of this study was to investigate the relationship between eating behaviors, body dissatisfaction, self-esteem, and perfectionism in a sample of Portuguese girls. METHOD A community sample of 575 Portuguese girls attending secondary school, answered self-report questionnaires including data on weight, height, and the Portuguese versions of the Contour Figures Rating Scale, the Child and Adolescent Perfectionism Scale, the Children Eating Attitudes Test, and the Rosenberg Self-Esteem Scale. SPSS version 20.0 for Windows was used for statistical analyses. RESULTS High scores in the Children Eating Attitudes Test were associated with significantly higher levels of body dissatisfaction (r = 0.339), socially prescribed perfectionism (r = 0.175), self-oriented perfectionism (r = 0.211), and low self-esteem (r = -0.292) (all p < 0.001). Self-oriented perfectionism partially mediated the relation between body dissatisfaction and disordered eating behaviors. CONCLUSION In this sample, dysfunctional eating behaviors appeared to correlate strongly with body dissatisfaction, low self-esteem, and perfectionism in girls. These themes should be addressed among female adolescents in the community.

Abstract
This study explored the moderating effect of body dissatisfaction (BD) on the relationship between perfectionism and weight restricting and control behaviours (WRCBs). A sample of 167 female undergraduates completed self-report measures of perfectionism, BD and WRCBs. BD was not found to moderate the relationship between either perfectionism and dieting, or perfectionism and exercise. Instead, BD uniquely predicted both dieting and exercise, as did the perfectionism dimensions of self-oriented perfectionism, concern over mistakes, parental standards, and organisation. BD moderated the relationship between perfectionism and purging for analyses involving self-oriented perfectionism, concern over mistakes, and doubts about actions, such that there was a significant positive association between perfectionism and purging when BD was high but not low. Perfectionism and BD are important in different ways to WRCBs. The importance of measuring multiple dimensions of perfectionism and differentiating between the various types of WRCBs is highlighted.

Abstract
OBJECTIVE Perfectionism has long been known to correlate with eating disturbance (ED). One mechanism through which this personality tendency may lead to ED is through increasing one's daily perfectionistic thoughts. This study examined the mediating role of perfectionistic thinking in the personality perfectionism-ED relationship among both male and female college students, and included measures assessing both typically-male and typically-female ED symptoms. METHOD A majority-White sample of 140 males and 329 females completed online versions of the Multidimensional Perfectionism Scale (Hewitt & Flett, 1991), Perfectionism Cognitions Inventory (Flett, Hewitt, Blankstein, & Gray, 1998), Drive for Muscularity Scale (McCreary, Sasse, Saucier, & Dorsch, 2004), items from the Eating Disorder Examination Questionnaire (Fairburn, 2008), and other measures. Regression tests examined the hypothesized role of perfectionistic cognitions as a mediator, including participant age, BMI, and positive and negative affect as covariates. RESULTS Among women, relationships between both self-oriented (Sobel's statistic=-4.63, p<.001) and socially prescribed perfectionism (Sobel's statistic=-5.77, p<.001) and dieting behavior were fully mediated by increased perfectionistic thinking. Among men, however, the relationship between only self-oriented perfectionism and bulimic (but not dieting) behavior, was fully mediated by increased perfectionistic thinking (Sobel's statistic=-2.53, p=.01). CONCLUSIONS Perfectionistic cognitions play an important linking role between personality perfectionism and ED, and can illuminate important differences by gender in eating disturbance. Such findings can improve validity of ED assessment in both genders, and provide a clear pathway to interventions to decrease ED in both genders.

Abstract
Depression is a common psychological problem and females have been found to be at greater risk for this disorder than males. Although numerous studies have found that physical exercise is negatively associated with risk of depression, some studies suggest that negative exercise attitudes may increase the risk of depression. The present study used the survey method to examine the relationship between depressive symptoms, exercise performance dissatisfaction, body dissatisfaction, and physical exercise among a sample of 895 undergraduate university students. Females reported higher depression and exercise performance dissatisfaction scores than males; however, there were no gender differences in body dissatisfaction. Exercise performance dissatisfaction was positively associated with depression among both males and females. Physical exercise was negatively associated with depression among males, but not among females. The possibility of screening participants enrolled in exercise programs for performance dissatisfaction is discussed as negative exercise attitudes may diminish the positive impact of exercise on depressed mood.

Abstract
Self-evaluation closely dependent upon body shape and weight is one of the defining criteria for bulimia nervosa (BN). We studied 53 adult women, 17 with BN, 18 with a recent history of anorexia nervosa (AN), and 18 healthy comparison women, using three different fMRI tasks that required thinking about self-knowledge and social interactions: the Social Identity task, the Physical Identity task, and the Social Attribution task. Previously, we identified regions of interest (ROI) in the same tasks using whole-brain voxel-wise comparisons of the healthy comparison women and women with a recent history of AN. Here, we report on the neural activations in those ROIs in subjects with BN. In the Social Attribution task, we examined activity in the right temporoparietal junction (RTPJ), an area frequently associated with mentalization. In the Social Identity task, we examined activity in the precuneus (PreC) and dorsal anterior cingulate (dACC). In the Physical Identity task, we examined activity in a ventral region of the dACC. Interestingly, in all tested regions, the average activation in subjects with bulimia was more than the average activation levels seen in the subjects with a history of anorexia but less than that seen in healthy subjects. In three regions, the RTPJ, the PreC, and the dACC, group responses in the subjects with bulimia were significantly different from healthy subjects but not subjects with anorexia. The neural activations of people with BN performing fMRI tasks engaging social processing are more similar to people with AN than healthy people. This suggests biological measures of social processes may be helpful in characterizing individuals with eating disorders.

Abstract
Clinically significant trait perfectionism is often characteristic of individuals exhibiting symptoms of eating disorders. The present study reports on a measure developed to assess the use of food rules and evaluates the hypothesis that adherence to food rules may be one mechanism through which trait perfectionism exacerbates risk for developing eating disorder symptoms. Forty-eight female college students completed a battery of questionnaires, and multiple regression analyses were used to test a mediational model. Results indicated that adherence to food rules mediated the relationship between self-oriented perfectionism and three indices of disordered eating in this sample. This relationship was specific to self-oriented perfectionism and did not hold for other-oriented or socially prescribed perfectionism. These findings may have implications for designing early interventions for disordered eating and may be useful in tailoring treatment for individuals with disordered eating who also report high levels of perfectionism.

The Eating Disorder Inventory-2 Perfectionism scale: factor structure and associations with dietary restraint and weight and shape concern in eating disorders. Eat Behav 2012; 13:49-53. [PMID: 22177396 DOI: 10.1016/j.eatbeh.2011.09.007] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2011] [Revised: 09/10/2011] [Accepted: 09/29/2011] [Indexed: 11/22/2022]
Abstract
The Eating Disorder Inventory-2 Perfectionism subscale (EDI-P) was originally construed as a unidimensional measure of perfectionism. However, research in non-clinical samples suggests that the EDI-P measures two dimensions of perfectionism: self-oriented and socially prescribed perfectionism. This study aimed to investigate the factor structure of the EDI-P in a transdiagnostic sample of females seeking treatment for an eating disorder, and to determine the unique association between EDI-P dimensions, weight and shape concern, and dietary restraint in anorexia nervosa (AN), bulimia nervosa (BN), and eating disorder not otherwise specified. Two hundred and ninety nine females seeking treatment for an eating disorder at an outpatient eating disorder service completed the Eating Disorder Examination and the EDI-P. Confirmatory factor analysis supported a two-factor model of the EDI-P comprising self-oriented and socially prescribed perfectionism. Self-oriented perfectionism, but not socially prescribed perfectionism, accounted for unique variance in weight and shape concern and dietary restraint in both AN and BN. Results highlight the potential importance of self-oriented perfectionism in eating disorders and support the argument that self-imposed standards are central to perfectionism in eating disorders.

Abstract
OBJECTIVE Recent research has identified specific cognitive deficits in patients with anorexia nervosa (AN), including impairment in executive functioning and attention. Another such cognitive process, implicit category learning has been less studied in AN. This study examined whether implicit category learning is impaired in AN. METHOD Twenty-one women diagnosed with AN and 19 control women (CW) were administered an implicit category learning task in which they were asked to categorize simple perceptual stimuli (Gabor patches) into one of two categories. Category membership was based on a linear integration (i.e., an implicit task) of two stimulus dimensions (orientation and spatial frequency of the stimulus). RESULTS AN individuals were less accurate on implicit category learning relative to age-matched CW. Model-based analyses indicated that, even when AN individuals used the appropriate (i.e., implicit) strategy they were still impaired relative to CW who also used the same strategy. In addition, task performance in AN patients was worse the higher they were in self-reported novelty seeking and the lower they were in sensitivity to punishment. CONCLUSIONS These results indicate that AN patients have implicit category learning deficits, and given this type of learning is thought to be mediated by striatal dopamine pathways, AN patients may have deficits in these neural systems. The finding of significant correlations with novelty seeking and sensitivity to punishment suggests that feedback sensitivity is related to implicit learning in AN.

Abstract
This study examined the role of perfectionism (self-oriented and socially prescribed), shape and weight overvaluation, dichotomous thinking, and conditional goal setting in eating disorder psychopathology. Perfectionism and shape and weight overvaluation have had longstanding implication in the development and maintenance of eating disorders. A leading evidence-based theory of eating disorders (Fairburn, Cooper & Shafran, 2003) outlines perfectionism as a maintaining mechanism of eating disorder psychopathology and as a proximal risk factor for the development of shape and weight overvaluation. These constructs have been linked to other cognitive processes relevant to eating disorders, specifically, dichotomous thinking and conditional goal setting. Women with DSM-IV eating disorders (N=238) were compared to women in the general community (N=248) and, as hypothesised, scores on measures of these constructs were pronounced in the clinical sample. Hierarchical regression analyses predicting eating disorder psychopathology showed that for both groups, dichotomous thinking and conditional goal setting significantly improved model fit beyond perfectionism and shape and weight overvaluation alone. Self-oriented perfectionism, but not socially prescribed perfectionism, was relevant to eating disorder psychopathology. We discuss the implications for current treatment protocols and early intervention.

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 To compare general and eating disorder-specific psychopathology in patients with acute anorexia nervosa (acAN), weight-recovered patients (recAN) and healthy control women (HCW). METHODS One hundred anorexia nervosa patients (66 acAN and 34 recAN) and 88 HCW were included in our study. Psychopathology was assessed by self-report questionnaires [Symptom Check List 90 Revised (SCL-90-R), Eating Disorder Inventory-2 (EDI- 2)] as well as by interview [Structured Interview of Anorexia Nervosa and Bulimic Syndromes (SIAB-EX)] and compared using multivariate analysis of variance. Plasma leptin levels were determined using enzyme linked immunosorbent assay. RESULTS Mean comparisons indicated highly significant differences between acAN and recAN subjects on all psychopatholgy variables, except for perfectionism. RecAN subjects did not differ from HCW. Partial weight recovery was associated with decreasing levels of psychopathology. Correlational analyses suggested strong negative associations between leptin levels and psychopathology. CONCLUSION Prolonged malnutrition, as indicated by suppressed plasma leptin levels, is strongly related to eating disorder-specific as well as general psychopathological symptoms. Weight recovery is associated with the absence of psychopathology. These data emphasize the interaction between somatic and psychological variables.

Abstract
Eating disorders are believed to range across a spectrum of varying degrees of obsessive-compulsive and impulsive behavior. Sixty anorexic (mean age = 19.8; sd = 5.9) and 109 bulimic (mean age = 26.9; sd = 11.3) female patients completed self-report questionnaires assessing obsessive-compulsiveness, impulsivity, depression and anxiety, as well as two eating disorder scales. Results yielded significantly higher levels of impulsivity and negative body image in the bulimic compared to the anorexic group. Regression analysis predicting impulsivity showed that bulimia and negative body image were the main contributors. Regression analysis for predicting obsessive-compulsive behavior suggested that depression and anxiety obscure the link between anorexia and obsessive-compulsive behavior, and a high BMI intensifies the association between anxiety and obsessive-compulsive behavior. The high rates of both impulsivity and obsessive-compulsiveness found in both groups, and their association with the severity of the eating disorder, may suggest that impulsivity and obsessive-compulsiveness are not mutually exclusive and can both be found among anorexic and bulimic patients.

Abstract
This study examined potential differences and similarities between attitudes about body shape and eating behaviors in Japan versus America. Discrepancies between various body ideals (e.g., own versus ideal; Japanese versus American) and perceived weight status were examined in a sample of adult Japanese women. Forty-five adult Japanese women rated various body ideals using the Stunkard Body Shape Questionnaire. They also answered questions about their perceived body weight and completed the Eating Disorders Inventory (EDI-2). Participants rated the ideal body shape for Japanese women to be significantly thinner than for American women. Body image discrepancy predicted drive for thinness and bulimic symptoms as measured by the EDI-2. Furthermore, there was an interaction between perfectionism and perceived overweight status, such that among participants high on perceived weight status, perfectionism predicted greater bulimic symptomology. The relative importance of the internalization of the Western beauty ideal to the rise of eating disorders in Japan is discussed. Similarities between the findings of this study and studies conducted on American samples are highlighted, and areas for future research are proposed.
