Obsessive compulsive symptoms at initial presentation of adolescent eating disorders

Perfectionism and eating disorders in children and adolescents: A systematic review and meta-analysis

There is a consistent link between perfectionism and eating disorders, however no meta-analysis to date has synthesized this literature in children and adolescents. We hypothesized that there would be significant, small pooled correlations between perfectionism dimensions and eating disorder symptoms in children and adolescents. Published, peer-reviewed articles with standardised measures of perfectionism and eating disorder symptoms were included. Articles were excluded if the age range was over 18 years. Overall, 39 studies were included (N = 13,954 participants, M age = 13.7 years). Total perfectionism (r = 0.25), perfectionistic strivings (r = 0.21), and perfectionistic concerns (r = 0.31) had significant positive associations with eating disorder symptoms. Most studies were rated as fair or good quality. Limitations included high heterogeneity, insufficient studies to investigate age as a moderator, the inclusion of only English articles, and predominately cross-sectional studies which precluded causal inference. Higher perfectionism was associated with greater eating disorder symptoms in children and adolescents. Future research should focus on longitudinal studies of eating disorder symptoms in children and adolescents.

The relationship between perfectionism and eating-related symptoms in adolescents: A systematic review

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.

Eating Disorders: An Evolutionary Psychoneuroimmunological Approach

Eating disorders are evolutionarily novel conditions. They lead to some of the highest mortality rates of all psychiatric disorders. Several evolutionary hypotheses have been proposed for eating disorders, but only the intrasexual competition hypothesis is extensively supported by evidence. We present the mismatch hypothesis as a necessary extension to the current theoretical framework of eating disorders. This hypothesis explains the evolutionarily novel adaptive metaproblem that has arisen when mating motives conflict with the large-scale and easy availability of hyper-rewarding but obesogenic foods. This situation is exacerbated particularly in those contemporary environments that are characterized by sedentary lifestyles, ever-present junk foods, caloric surplus and the ubiquity of social comparisons that take place via social media. Our psychoneuroimmunological model connects ultimate-level causation with proximate mechanisms by showing how the adaptive metaproblem between mating motives and food rewards leads to chronic stress and, further, to disordered eating. Chronic stress causes neuroinflammation, which increases susceptibility to OCD-like behaviors that typically co-occur with eating disorders. Chronic stress upregulates the serotonergic system and causes dysphoric mood in anorexia nervosa patients. Dieting, however, reduces serotonin levels and dysphoric mood, leading to a vicious serotonergic-homeostatic stress/starvation cycle whereby cortisol and neuroinflammation increase through stringent dieting. Our psychoneuroimmunological model indicates that between-individual and within-individual variation in eating disorders partially arises from (co)variation in gut microbiota and stress responsivity, which influence neuroinflammation and the serotonergic system. We review the advances that have been made in recent years in understanding how to best treat eating disorders, outlining directions for future clinical research. Current evidence indicates that eating disorder treatments should aim to reduce the chronic stress, neuroinflammation, stress responsivity and gut dysbiosis that fuel the disorders. Connecting ultimate causes with proximate mechanisms and treating biopsychosocial causes rather than manifest symptoms is expected to bring more effective and sophisticated long-term interventions for the millions of people who suffer from eating disorders.

Adolescent perfectionism: Structural features of the Frost Multidimensional Perfectionism Scale and correlates with attachment and psychopathology

OBJECTIVES

Perfectionism is recognized as a significant risk factor for psychopathology. Emerging research links attachment to perfectionism in adult and college-age samples. The Frost Multidimensional Perfectionism Scale (FMPS) has been used in adults and adolescents with a variety of factor structures found. This study sought to establish the factor structure in a general adolescent sample prior to testing for associations between perfectionism, attachment, and psychopathology in the same sample.

DESIGN

A cross-sectional survey design was used. Confirmatory factor analysis, and correlational and regression analyses were employed.

METHODS

A total of 290 adolescents, aged 12-18 years, were recruited from a state secondary school. All completed the FMPS along with brief measures of attachment and psychopathology.

RESULT

Exploratory and confirmatory factor analyses failed to replicate previously published models, and a new six-item, 1-factor model representing perfectionism was found instead. This new variable was then used to establish a role for perfectionism and attachment anxiety in predicting internalizing problems. Perfectionism also correlated with conduct problems and hyperactivity.

CONCLUSION

This study established a novel factor structure for the FMPS, allowing proof of principle of the role of perfectionism in a relationship with attachment and psychopathology, which after replication, may inform new interventions for perfectionism. Caution is noted about the use of extant perfectionism measures that are not properly developmentally informed and which do not capture the dynamic nature of adolescence and adolescent perfectionism.

PRACTITIONER POINTS

Perfectionism is a feature of adolescent psychopathology, including internalizing and externalizing problems. Perfectionism is associated with attachment anxiety and together contributes to internalizing problems. Current conceptualizations of perfectionism may not capture the specific developmental and dynamic aspects of adolescence and should not be regarded as a stable personality trait.

Eating disorders

Twenty years have passed from the International Classification of Diseases, Tenth Revision (ICD-10) to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and, in the meanwhile, a lot of research data about eating disorders has been published. This article reviews the main modifications to the classification of eating disorders reported in the "Feeding and Eating Disorders" chapter of the DSM-5, and compares them with the ICD-10 diagnostic guidelines. Particularly, we will show that DSM-5 criteria widened the diagnoses of anorexia and bulimia nervosa to less severe forms (so decreasing the frequency of Eating Disorders, Not Otherwise Specified (EDNOS) diagnoses), introduced the new category of Binge Eating Disorder, and incorporated several feeding disorders that were first diagnosed in infancy, childhood, or adolescence. On the whole, the DSM-5 revision should allow the clinician to make more reliable and timely diagnoses for eating disorders.

Diet and Doubt: A Clinical Case Study of Inference-Based Therapy for Bulimia Nervosa

There is a recognized overlap between eating disorders (EDs) and obsessive-compulsive disorder (OCD) in terms of diagnosis, phenomenology, epidemiology, and psychological characteristics related to the disorder. In light of these similarities, a cognitive inference-based therapy (IBT) program, shown to be effective in treating OCD, was adapted for EDs. This case study describes the application of IBT treatment for a 35-year-old woman diagnosed with bulimia nervosa who also demonstrated overvalued ideation related to her body weight and shape. Over a 20-week period, the client's ED pathology significantly decreased. Notably, the frequency of binge episodes was reduced by 90% from pre- to posttreatment and by 100% at 6-month follow-up. Significant reductions were also observed in dietary restriction and overvalued ideation. This case study has important implications for the treatment of individuals with both an ED and strong overvalued ideas.

Depressive mood, eating disorder symptoms, and perfectionism in female college students: a mediation analysis

Although perfectionism has long been established as an important risk factor for depressive mood and eating disorders, the mechanisms through which this temperamental predisposition mediates the relationship between depressive mood and eating disorder symptoms are still relatively unclear. In this study we hypothesized that both perfectionism dimensions, self-oriented perfectionism and socially prescribed perfectionism, would mediate the relationship between current symptoms of depression and eating disorders in a non-clinical sample of Spanish undergraduate females. Two hundred sixteen female undergraduate students of the University Complutense of Madrid (Spain) completed the Spanish versions of the Eating Attitudes Test (EAT-40), the Multidimensional Perfectionism Scale (MPS), OBQ-44, and BDI-II and BAI. Results demonstrated the importance of socially prescribed perfectionism in mediation of the relationship between depressive mood and symptoms of eating disorders. Socially prescribed perfectionism mediates the relationship between depressive mood and eating disorder symptoms for female college students.

Cognitive flexibility in verbal and nonverbal domains and decision making in anorexia nervosa patients: a pilot study

BACKGROUND

This paper aimed to investigate cognitive rigidity and decision making impairments in patients diagnosed with Anorexia Nervosa Restrictive type (AN-R), assessing also verbal components.

METHODS

Thirty patients with AN-R were compared with thirty age-matched healthy controls (HC). All participants completed a comprehensive neuropsychological battery comprised of the Trail Making Test, Wisconsin Card Sorting Test, Hayling Sentence Completion Task, and the Iowa Gambling Task. The Beck Depression Inventory was administered to evaluate depressive symptomatology. The influence of both illness duration and neuropsychological variables was considered. Body Mass Index (BMI), years of education, and depression severity were considered as covariates in statistical analyses.

RESULTS

The AN-R group showed poorer performance on all neuropsychological tests. There was a positive correlation between illness duration and the Hayling Sentence Completion Task Net score, and number of completion answers in part B. There was a partial effect of years of education and BMI on neuropsychological test performance. Response inhibition processes and verbal fluency impairment were not associated with BMI and years of education, but were associated with depression severity.

CONCLUSIONS

These data provide evidence that patients with AN-R have cognitive rigidity in both verbal and non-verbal domains. The role of the impairment on verbal domains should be considered in treatment. Further research is warranted to better understand the relationship between illness state and cognitive rigidity and impaired decision-making.

Compulsive exercise and eating disorders

The aim of this review was to develop an empirically supported cognitive behavioural model of compulsive exercise within the context of the eating disorders. A systematic review of the correlates and predictors of compulsive exercise among eating disordered patients identified four key correlates. These were subsequently validated by a second review, incorporating both the clinical and non-clinical as well as the exercise science literatures. A proposed model is presented which is both evidence-based and testable.

Application of the Transdiagnostic Cognitive-Behavioral Model of Eating Disorders to the Athletic Population

The purpose of this study was twofold: to explore the utility of components related to the transdiagnostic cognitive-behavioral model of eating disorders within an athletic population and to investigate the extent to which the model can be applied across gender, sport type, and performance standard to explain eating psychopathology. Five hundred and eighty-eight (N = 588) male and female British athletes completed a battery of self-report instruments related to eating psychopathology, interpersonal diffculties, perfectionism, self-esteem, and mood. Structural equation modeling revealed that eating psychopathology may arise from an interaction of interpersonal diffculties, low self-esteem, high levels of self-critical perfectionism, and depressive symptoms. Analysis further highlighted that the manner in which eating psychopathology may arise is invariant across athletes’ sport type and performance standard, but not across gender. The current findings suggest that the tested components of the transdiagnostic cognitive-behavioral model are pertinent and useful in explaining eating psychopathology among athletes.

Psychologic correlates of eating attitudes in Turkish female college students

OBJECTIVE

The purpose of this study is to determine the frequency and correlates of disordered eating attitudes in a university-sample Turkish female population and to evaluate the contribution of maternal psychopathologic symptoms and family functioning.

METHOD

Female students (n = 267; mean age, 21.21 +/- 1.88 years) completed the Eating Attitude Test, Beck Depression Inventory, 20-item Toronto Alexithymia Scale, Symptom Check List 90-R, and Family Assessment Device. Mothers (n = 96; mean age = 46.41 +/- 5.31 years) completed the Beck Depression Inventory, 20-item Toronto Alexithymia Scale, and Symptom Check List 90-R.

RESULTS

Twelve percent of the female college students had abnormal eating attitudes. Disordered eating attitudes were positively correlated with depression, obsessive-compulsive symptoms, and phobic anxiety. Eating attitude of the student sample was positively correlated with the mothers' obsessive-compulsive symptoms, phobic anxiety, and general psychopathology and "affective involvement" in family functioning.

CONCLUSIONS

It is necessary to pay attention to the levels of depression, alexithymia, anxiety, and obsession-compulsions, as well as family functioning and maternal psychopathology.

The combined presence of obsessive compulsive behaviors in males and females with eating disorders account for longer lengths of stay and more severe eating disorder symptoms

The goal of this study was to analyze the impact of obsessive compulsive behaviors (OCB) in eating disorder males and females admitted for residential treatment in terms of length of stay and severity of symptoms. Patients (N=384) were separated into four groups based on gender and the score obtained for the Maudsley Obsessive-Compulsive Inventory at admission. The instrument used to assess severity of eating disorder symptoms was the Eating Disorder Inventory (EDI-2) at admission and discharge. The results showed that the presence of comorbid OCB in eating disordered males and females account for longer length of stay (LOS) and an increased severity of eating disorder symptoms. Clinically, these findings point to the need for development of more targeted residential programs that are equipped for and adept at treating the comorbid eating disorder/OCB patient population.

Perfectionism and eating disorders: Current status and future directions

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.

Cognitive flexibility in anorexia nervosa and bulimia nervosa

The aim of this study was to determine if there are differences in cognitive flexibility in anorexia nervosa and bulimia nervosa. Fifty-three patients with an eating disorder (34 with anorexia nervosa and 19 with bulimia nervosa) and 35 healthy controls participated in the study. A battery of neuropsychological tests for cognitive flexibility was used, including Trail Making B, the Brixton Test, Verbal Fluency, the Haptic Illusion Test, a cognitive shifting task (CatBat) and a picture set test. Using exploratory factor analysis, four factors were obtained: 1: Simple Alternation; 2: Mental Flexibility; 3: Perseveration; and 4: Perceptual Shift. Patients with anorexia nervosa had abnormal scores on Factors 1 and 4. Patients with bulimia nervosa showed a different pattern, with significant impairments in Factors 2 and 4. These findings suggest that differential neuropsychological disturbance in the domain of mental flexibility/rigidity may underlie the spectrum of eating disorders.

Obsessive-compulsive disorder in childhood and adolescence

Obsessive-compulsive disorder (OCD) is a common psychiatric condition during childhood and adolescence, which continues to be underestimated and undertreated. For these reasons, it constitutes a primary cause of major disabilities in those ages and, sometimes, of permanent impairments later on. In these last few years, childhood and adolescence OCD has attracted an increasing focus which has promoted a deeper awareness of this illness, a better recognition with earlier interventions, as well as the set-up of more tailored and specific strategies, including psychotropic drugs. The aim of this paper is to present a critical review of paediatric OCD, with a special attention towards the most compelling reports available up to now and towards the most interesting areas for future research.
