Anxiety as a Mediator Between Perfectionism and Eating Disorders

intervenção cognitivo-comportamental em grupo com indivíduos com obesidade

A obesidade tem causas multifatoriais e a Terapia Cognitivo-Comportamental apresenta resultados positivos sobre os aspetos cognitivos, emocionais e comportamentais relativos à perda de peso. Este estudo apresenta uma avaliação preliminar do Programa Cognitivo Comportamental de Educação Alimentar em Grupo (PROMETA). Foi realizado um estudo quantitativo, pré-experimental com avaliação pré e pós-teste. Sessenta e sete participantes adultos com sobrepeso ou obesidade realizaram as 12 sessões da intervenção em grupos. Foram utilizados os inventários Beck de depressão, de ansiedade, e de desesperança, a escala de compulsão alimentar periódica, e a escala de figuras de silhuetas. Os resultados indicaram que o PROMETA contribuiu para redução de sintomas de depressão, ansiedade, desesperança, e compulsão alimentar. Portanto, o programa apresenta resultados satisfatórios para esta amostra.

Different clusters of perfectionism in inpatients with anorexia nervosa and healthy controls

Perfectionism is a risk and maintaining factor for anorexia nervosa (AN) but studies on its classification are lacking. This study aimed to classify patients with AN and healthy controls (HCs) according to their perfectionism; to evaluate the association between perfectionism clusters and severity of general and eating psychopathology for both groups; to investigate the relationship between baseline perfectionism and hospitalization outcome for patients. A sample of 207 inpatients with AN and 292 HCs completed: Eating Disorders Inventory-2, Frost Multidimensional Perfectionism Scale, Beck Depression Inventory, and State- Trait Anxiety Inventory. Cluster analyses were run to classify participants according to their perfectionism scores. Three clusters (i.e., high, medium, low perfectionism) emerged for both patients with AN and HCs. The high perfectionism cluster was over-represented among patients. Both groups reported significant differences across clusters in eating-related difficulties. In AN, anxiety and depression severity varied across clusters according to perfectionism, but patients' baseline perfectionism was unrelated to hospitalization outcome. Inpatients with AN and HCs could be grouped in clusters of high, medium, and low perfectionism which also mirrored their eating psychopathology severity. Finally, hospitalization outcome was unrelated to inpatients' baseline perfectionism.

Mediating Mechanisms of Perfectionism: Clinical Comorbidity of OCD and ED

Obsessive-compulsive disorder (OCD) and eating disorders (ED) share common causal factors and often represent similar entities. Studies on obsessive-compulsive disorders and eating disorders reveal a significant correlation between maladaptive perfectionism. The objective of this study is to evaluate the predictive variables of perfectionism in patients diagnosed with Anorexia Nervosa (AN), Bulimia Nervosa (BN) and OCD using a structural equation model (SEM). The sample consisted of 187 participants (60.9% women, 39.1% men) with a mean age of 26.68 (SD = 10.97). The findings reveal that the model is the same in all the disorders evaluated, achieving an adequate fit: χ2 = 7.95 (p = 0.000), RMSEA = 0.087 (95% confidence interval: 0.00 to 0.02), CFI = 0.991, TLI = 0.951 and with an overall predictive capacity of around 30% (CD = 0.318). It is recommended that future studies address the subtypes of disorders evaluated using longitudinal designs.

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.

Are Adherence to the Mediterranean Diet, Emotional Eating, Alcohol Intake, and Anxiety Related in University Students in Spain?

Research has suggested that university students are at risk from certain unhealthy habits, such as poor diet or alcohol abuse. At the same time, anxiety levels appear to be higher among university students, which may lead to high levels of emotional eating. The aim of this study was to analyze the degree of adherence to the Mediterranean diet (AMD), emotional eating, alcohol intake, and anxiety among Spanish university students, and the interrelationship of these variables. A total of 252 university students filled out the Mediterranean Diet Quality Index (KIDMED) questionnaire for Mediterranean diet adherence, an Alcohol Use Disorders Identification Test, a State-Trait Anxiety Inventory and the Emotional Eater Questionnaire. We analyzed descriptive data, a t-test and analysis of variance (ANOVA) for differences, a Pearson correlation, and multiple regression tests. Results showed low levels of AMD among university students (15.5%) and considerable levels of emotional eating (29%) and anxiety (23.6%). However, levels of alcohol dependence were low (2.4%). State-anxiety was a predictor of the emotional eater score and its subscales, and sex also was predictive of subscale guilt and the total score. However, AMD was predicted only by trait-anxiety. These models accounted for between 1.9% and 19%. The results suggest the need for the implementation of educational programs to promote healthy habits among university students at risk.

Assessment of Family Functioning and Eating Disorders - The Mediating Role of Self-Esteem

The aim of the study was to measure whether people at increased risk for eating disorders (EDs) and people without an increased risk of EDs differ from each other in the assessment of family functioning (FF) and self-esteem (SE) dimensions. Moreover, the correlations between FF, EDs, and SE were verified, looking for the mediating role of SE in the context of the FF and EDs. The research was conducted on the group of 160 people aged from 18 to 47 years, including 74 people at increased risk for EDs. We used: The Family APGAR (Adaptability, Partnership, Growth, Affection, and Resolve); The SCOFF Questionnaire; The Multidimensional Self-Esteem Inventory, MSEI. Analyses indicate that the compared groups differ significantly in terms of EDs, assessment of FF, and all components of SE, in such a way that people without an increased risk of EDs are characterized by a more positive assessment of FF and higher SE in all its dimensions. All SE dimensions, except defensive high SE, are mediators in the relationship of FF with EDs. In therapeutic interactions, it is worth focusing on the SE dimensions, as they are one of the mediation elements in the relationship between the assessment of FF and EDs.

An examination of direct, indirect and reciprocal relationships between perfectionism, eating disorder symptoms, anxiety, and depression in children and adolescents with eating disorders

OBJECTIVE

Perfectionism is a transdiagnostic factor across eating disorders, anxiety, and depression. Previous research has shown anxiety mediates the relationship between perfectionism and eating disorders in adults. The aim of this study was to investigate the relationships between anxiety/depression, perfectionism and eating disorder symptoms in children and adolescents with eating disorders.

METHOD

Structural equation modeling was used to investigate three models in a clinical sample of children and adolescents (N = 231, M age = 14.5, 100% female): (1) anxiety and depression as mediators of the relationship between perfectionism and eating disorder symptoms, (2) eating disorder symptoms as a mediator of the relationship between perfectionism and anxiety and/or depression, and (3) perfectionism as a mediator of the relationship between anxiety/depression and eating disorders.

RESULTS

Results indicated that both models 1 and 2 fit the data well, while model 3 provided a poor fit. These findings suggest that in clinical populations of children and adolescents, anxiety and depression mediate the relationship between perfectionism and eating disorder symptoms, and there is also a reciprocal relationship whereby eating disorders mediate the association between perfectionism, and anxiety and/or depression.

DISCUSSION

The results highlight the importance of further research to determine whether targeting perfectionism is helpful in the treatment of eating disorders and comorbid anxiety and depression in young people. It would be useful for clinicians to consider assessing for and treating perfectionism directly when it is elevated in children and adolescents with eating disorders.

Meal and snack-time eating disorder cognitions predict eating disorder behaviors and vice versa in a treatment seeking sample: A mobile technology based ecological momentary assessment study

Individuals with eating disorders experience high anxiety when eating, which may contribute to the high relapse rates seen in the eating disorders. However, it is unknown if specific cognitions associated with such anxiety (e.g., fears of gaining weight) may lead to engagement in eating disorder behaviors (e.g., weighing oneself). Participants (N = 66) recently treated at a residential eating disorder facility and diagnosed with an eating disorder (primarily anorexia nervosa; n = 40; 60.6%) utilized a mobile application to answer questions about mealtime cognitions, anxiety, and eating disorder behaviors four times a day for one week. Hierarchical linear models using cross-lag analyses identified that there were quasi-causal (and sometimes reciprocal) within-person relationships between specific eating disorder cognitions and subsequent eating disorder behaviors. These cognitions predicted higher anxiety during the next meal and eating disorder pathology at one-month follow-up. Interventions personalized to target these specific cognitions in real time might reduce eating disorder relapse.

Emotional reactivity and blood pressure elevations: anxiety as a mediator

There is a strong link between emotional reactivity and hypertension, yet little research to date has examined mediators of this relationship. Ourstudy  investigated the mediating roleof anxiety on the relationship between emotional reactivity and blood pressure elevations. Participants were226 hypertensive patients (93 men and 133 women, Mean age = 53.09, SD = 13.88 years), purposivelydrawn from the General Outpatient Department in University of Calabar Teaching Hospital, Calabar, , Nigeria. .  Measures for data collection were Emotional Reactivity Scale, State Trait Anxiety Inventory, and the Mercury Sphygmomanometer. Hayes PROCESS macro for SPSS which uses a regression-based, path-analytical framework, was employed in analysing the data. Results showed that emotional reactivity was positively associated with blood pressure elevations. Anxiety was positively associated with blood pressure elevations. Anxiety also fully mediated the relationship between emotional reactivity and blood pressure elevations, even after adjusting for the control variables (e.g., age, family history of hypertension, and educational status). The finding suggests that being less emotionally reactive is associated with a decrease in disabling influences of anxiety, thereby contributing to lower levels of mean arterial blood pressure. The findings may be helpful  in improving prevention, control and management of hypertension in healthcare.

The relationship of anthropometric measurements with psychological criteria in female athletes

Sports and exercise settings as well as other socio-cultural environments emphasize a thin and physically fit female body. However, there is a clear need for a better understanding of the physical and psychological correlates of social physique anxiety and body image dissatisfaction in female athletes. This study aimed to examine the association of the social physique anxiety, body image satisfaction, and personality with the anthropometric measurements in female college athletes according to their sport type using the Co-Plot technique. The sample included 63 female athletes ranging in age from 18 to 26. Results of the Co-Plot analysis revealed a significant association among social physique anxiety, personality and anthropometric measurements. This means that certain physical measurements may lead to greater social physique anxiety and body image dissatisfaction in female athletes. It was found that females having higher levels of social physique anxiety and thus, lower levels of body image satisfaction may be less emotionally stable and more negatively perfectionist. In conclusion, the results of the present study provided evidence to the claim that both physical self-perception and anthropometric measurements may be closely associated with psychological criteria in female athletes.

Commentary on Empirical Examinations of the Association between Anxiety and Eating Disorders

A substantial body of research supports comorbidity between eating and anxiety disorders, and articles in this special section explore the nature of this association using severity different research designs. This commentary reviews findings from these articles included, focusing on inferences that may be drawn from each design. Collectively, articles support the need for future studies to examine whether eating and anxiety disorders share underlying mechanisms. If identified, such mechanisms could create opportunities for transdiagnostic interventions that ameliorate suffering from both eating and anxiety disorders.
