The role of stress in the association between low self-esteem, perfectionism, and worry, and eating disorders

Metacognitive interpersonal therapy-eating disorders versus cognitive behavioral therapy for eating disorders for non-underweight adults with eating disorders: study protocol for a pilot pre-registered randomized controlled trial

Eating disorders (ED) are serious disorders characterized by an alteration of eating habits and excessive concern about weight and body shapes (Fairburn, 2002), accompanied by significant impairment inequality of life, high mortality rates and serious organic consequences (Jenkins et al., 2011; Treasure et al., 2015; 2020). Although evidence-based psychological therapies for nonunderweight ED presentations such as cognitive behavioral therapy for eating disorders (CBT-ED) are widely available, there is substantial scope for improvements, particularly in terms of efficacy and adherence. One option is to develop interventions to address elements of pathology not fully addressed by existing empirical supported treatments, such as incorporating techniques aimed at addressing interpersonal problems and personality disorder features into existing treatment delivery. We adapted Metacognitive Interpersonal Therapy, a psychological intervention supported by evidence for treating personality disorders and integrated it with existing CBT techniques for eating disorders (MIT-ED). MIT-ED targets aspects of ED that are not included in the transdiagnostic CBT-E model such as poor metacognition, or maladaptive interpersonal schemas. This is a pre-registered (Protocol number: 0000781) pilot randomized clinical trial aimed at assessing acceptability and feasibility of MIT-ED and establishing preliminary evidence of effectiveness for future larger studies. Twenty patients (10 in each arm) will be randomized to 20 sessions of individual psychotherapy, either MIT-ED or CBTE. Repeated follow-ups will be collected up to 24 months. Participants are recruited at a private outpatient clinic for ED treatment. Acceptability will be assessed via session attendance, completion rates and preliminary outcomes. The primary outcome is ED pathology assessed with the Eating Disorder Examination Questionnaire-6. Other ED outcomes assessed will be eating disorder attitudes, clinical impairment and binge eating pathology. Secondary treatment outcomes are anxiety, depression, and global symptomatology. We will also assess emotional awareness, emotion regulation and therapeutic alliance. Based on previous studies of MIT for personality disorders we hypothesize that MIT-ED will be acceptable to patients, evidenced by high treatment adherence and retention. We hypothesize that MIT-ED will be associated with reductions in eating disorder pathology, at least equivalent to CBT-E. Results will be used to inform the study design, sampling, likely effect sizes and choice of outcome measures for future larger trials of MIT-ED in ED samples.

Dancing in a culture of disordered eating: A feminist poststructural analysis of body and body image among young girls in the world of dance

Eating disorders among adolescent girls are a public health concern. Adolescent girls that participate in aesthetic sport, such as dance, are of particular concern as they experience the highest rates of clinical eating disorders. The purpose of this study is to explore the experiences of young girls in the world of competitive dance and examine how these experiences shape their relationship with the body; feminist poststructural discourse analysis was employed to critically explore this relationship. Interviews were conducted across Canada with twelve young girls in competitive dance (14–18 years of age) to better understand how the dominant discourses in the world of competitive dance constitute the beliefs, values and practices about body and body image. Environment, parents, coaches, and peers emerged as the largest influencers in shaping the young dancers’ relationship with their body. These influencers were found to generate and perpetuate body image discourses that reinforce the ideal dancer’s body and negative body image.

The role of positive self-compassion, distress tolerance, and social problem-solving in the relationship between perfectionism and disordered eating among racially and ethnically diverse college students

Eating disorders (EDs) are associated with high levels of distress, functional impairment, and morbidity. Perfectionism has been consistently identified as an important factor in the etiology and maintenance of disordered eating, and as a promising target for treatment efforts. To address the detrimental effects of perfectionism on disordered eating, further research is needed to better understand what mechanisms may influence the relationship between these variables. In the present research, we examined three constructs related to self-regulation as potential mediators of the relationship between perfectionism and disordered eating: positive self-compassion, distress tolerance, and social problem-solving. We collected data from a sample of racially and ethnically diverse undergraduate students (N = 280) using an online questionnaire battery. Using structural equation modeling (SEM), we developed measurement and structural models to meet criteria for good fit and tested the hypothesized relationships. Distress tolerance emerged as a robust, statistically significant mediator of the relationship between perfectionism and disordered eating. Social problem-solving and self-compassion did not mediate this relationship. Distress tolerance may counterbalance the cognitive load associated with perfectionism; freeing up mental resources to focus on resisting urges for immediate relief through engagement in maladaptive disordered eating.

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.

How deep is your thought? The relations between intolerance of uncertainty, worry and weight and shape concerns in adolescent girls with anorexia nervosa

BACKGROUND

Inherent to anorexia nervosa are repetitive thoughts about weight and shape. Growing research suggests the relevance of intolerance of uncertainty and worry in maintaining these types of repetitive thoughts. The relation between these cognitive processes and weight and shape concerns in adolescent girls with anorexia nervosa is understudied. This study investigated associations between prospective (desire for predictability) and inhibitory (uncertainty paralysis) intolerance of uncertainty, and weight and shape concerns and the mediating role of worry in these associations.

METHODS

In a cross-sectional study, 93 adolescent girls with anorexia nervosa completed questionnaires measuring the variables of interest. A mediation model with worry as a mediator between inhibitory and prospective intolerance of uncertainty and weight and shape concerns was tested.

RESULTS

A total and direct effect of inhibitory intolerance of uncertainty on weight and shape concerns was found. Worry did not mediate this relation.

CONCLUSIONS

These results confirm the importance of inhibitory intolerance of uncertainty in adolescent girls with anorexia nervosa, more specifically to weight and shape concerns. This group may benefit from intervention strategies targeting intolerance of uncertainty. General worry seems less relevant to weight and shape concerns in adolescent girls with anorexia nervosa. Adolescent girls with anorexia nervosa often experience repetitive thoughts about weight and shape. Growing research suggests the relevance of intolerance of uncertainty and worry in maintaining these types of repetitive thoughts. Intolerance of uncertainty is defined as the incapacity to tolerate uncertainty and is often divided into two components; prospective intolerance of uncertainty (desire for predictability) and inhibitory intolerance of uncertainty (uncertainty paralysis). The relation between intolerance of uncertainty, worry and weight and shape concerns in adolescent girls with anorexia nervosa is understudied. This study aims to investigate study relations between prospective and inhibitory intolerance of uncertainty, worry, and weight and shape concerns. A total of 93 adolescent girls with anorexia nervosa completed three questionnaires, measuring prospective and inhibitory intolerance of uncertainty worry, and weight and shape concerns, respectively. The results of this study confirmed the importance of inhibitory intolerance of uncertainty in adolescent girls with anorexia nervosa, more specifically to weight and shape concerns. This group may benefit from intervention strategies targeting intolerance of uncertainty. General worry seems less relevant to weight and shape concerns in adolescent girls.

What role can accredited exercise physiologists play in the treatment of eating disorders? A descriptive study

Including exercise alongside other therapeutic approaches may help to address dysfunctional exercise use and improve eating disorder treatment outcomes. However, traditional treatment teams often lack the expertise needed to safely prescribe exercise. The aims of this study were to explore the perceptions and experiences of Accredited Exercise Physiologists (AEPs) relating to working with clients diagnosed with eating disorders to identify the role they play in the treatment of eating disorders and identify future training needs. Individual semi-structured telephone interviews were conducted with 12 (n = 9 females) AEPs working in the eating disorders field. Thematic analysis was conducted to extract major themes from the interview transcripts. Five major themes were identified: (1) The role of AEPs in the treatment of individuals with eating disorders is comprehensive; (2) Treatment is more effective when all components are addressed; (3) The absence of therapeutic exercise within standard treatment protocols reflects limitations of traditional scope of practice and knowledge about the role of AEPs; (4) Methods of acquiring further knowledge are insufficient for those in current practice; and (5) Accredited comprehensive training is currently unavailable but needed. This qualitative study showed that AEPs believe they can play a major role in the treatment of eating disorders and that treatment outcomes for individuals are likely to be greatly enhanced when dysfunctional exercise is addressed. Multidisciplinary training is needed.

COVID-19 and eating disorder and mental health concerns in patients with eating disorders

BACKGROUND

The Coronavirus (COVID-19) pandemic dramatically transformed daily life for adolescents and young adults, altering social and physical environments. Previous research has shown such shifts in daily life to be especially challenging for people living with eating disorders (ED). However, the extent of this environmental change on ED symptoms and mental health (MH) has been relatively unexplored in patients with EDs. This study examines how young people with EDs feel the COVID-19 pandemic has affected their living environments as well as their ED and MH symptoms and motivation for ED recovery.

METHODS

Participants were enrollees in the Registry of Eating Disorders and their Co-morbidities OVER time in Youth (RECOVERY) who responded to an additional survey (n = 89) in July 2020 to assess their perceptions of the impact of the COVID-19 pandemic. Participants reported on concerns of their ED worsening due to increased time living in a "triggering environment" due to the pandemic as well as perceived COVID-related changes in intrusive ED thoughts, depression, anxiety, isolation, and motivation to recover. Logistic regression models, adjusted for age and ED diagnosis, examined the association of triggering environment with ED and MH symptoms.

RESULTS

The majority of respondents reported concern for worsening of their ED due to a "triggering environment" (63%). Most reported an increase in ED thoughts (74%), feelings of anxiety (77%), depression (73%), and isolation (80%) they perceived to be related to the pandemic. Nearly one-third reported decrease in motivation to recover (29%) they perceived to be related to the pandemic. After adjusting for age and ED diagnosis, participants who reported concern for worsening of their ED due to a triggering environment had nearly 18 times the odds of decreased motivation to recover (OR 18.1; 95% CI 3.37-97.4, p = 0.003) and nearly 24 times the odds of increased ED thoughts (OR 23.8; 95% CI 4.31-131.6, p < 0.001) compared to those who did not report concern for worsening of their ED due to a triggering environment.

CONCLUSIONS

Our findings demonstrate the perceived negative impact the COVID-19 pandemic has had on the self-reported ED and MH symptoms in patients with EDs, particularly in those who report concern for a negative environmental change. These results underscore the need for heightened monitoring of patients with EDs during the pandemic.

Perfectionism and Eating Behavior in the COVID-19 Pandemic

The novel coronavirus disease 2019 (COVID-19) represents a massive global health crisis leading to different reactions in people. Those reactions may be adaptive or not depending on situational or psychological processes. Disordered eating attitudes and behaviors are likely to be exacerbated by the pandemic through multiple pathways as suggested by Rodgers et al. (2020). Among the psychological variables that may have increased dysfunctional eating attitudes and behaviors as a consequence of the social distancing and isolation, we looked at perfectionism. Perfectionism is a well-recognized risk and maintaining factor of eating-related symptoms and interact with stress increasing the probability of dysfunctional reactions (e.g., Wang and Li, 2017). The present study investigated the relationship between multidimensional perfectionism and eating behaviors by considering the mediating role of psychological distress. Data were collected from two countries (Italy and Spain) by means of an online survey. The samples included 465 (63.4% female) participants from Italy and 352 (68.5% female) from Spain. Participants completed the short form of the Hewitt and Flett Multidimensional Perfectionism Scale (Lombardo et al., 2021) to assess self-oriented, other-oriented and socially prescribed perfectionism, as well as the short form of Three Factors Eating Questionnaire (Karlsson et al., 2000) and the Italian version of Depression Anxiety and Stress Scale-21 (Bottesi et al., 2015), respectively used to assess restrictive, emotional and uncontrolled eating on one hand, and depression, anxiety and stress on the other. Multigroup analysis was performed to test the hypothesized model. Results showed that other-oriented and socially prescribed perfectionism were indirectly related to most of the dysfunctional eating aspects through the mediation of psychological distress, and the pattern obtained was consistent in both countries. These findings evidence that the psychological distress potentially related to the COVID-19 disease mediates the negative impact of interpersonal perfectionism and the tendency to eat in response to negative emotions.

Exploring the relationship between health concerns and high-risk behaviours in Medical Sciences' students

Aim

The need to cope with life concerns may drive an individual to resort to high‐risk behaviours. This study aimed to determine the relationship between health concerns and high‐risk behaviours.

Design

A cross‐sectional study.

Methods

We sampled 926 Medical Sciences' students from the North of Iran from September–December 2017 using the stratified sampling method.

Results

The most and less common high‐risk behaviour was physical inactivity (97.5%) and high‐risk sexual behaviour (15.7%), respectively. In multivariate logistic regression analysis, participants' concerns about human sexuality (AOR: 1.39; CI: 1.22, 1.57), injury prevention and control (AOR: 1.12; CI: 1.01, 1.20), nutrition (AOR: 1.13; CI: 1.02, 1.26) and emotional health (AOR: 1.08; CI: 1.02, 1.15) increased the odds of risky behaviours. Among Medical Sciences' students, health concerns are linked with risky behaviours. The result of this study can be used to develop relevant interventions targeting mental health to reduce risky behaviour among youth.

Psychological characteristics and eating attitudes in adolescents with drunkorexia behavior: an exploratory study

PURPOSE

Drunkorexia represents an emerging phenomenon that is still understudied especially among adolescents. The present study aimed to investigate the relation between drunkorexia and psychological characteristics relevant and commonly associated with existing forms of eating disorders.

METHODS

The sample was composed of 849 adolescents (513 boys, 334 girls, 2 unknown; range 14-22) who completed a survey composed of Compensatory Eating and Behaviors in Response to Alcohol Consumption Scale and Psychological scales of the Eating Disorders Inventory-3.

RESULTS

Our findings highlighted that drunkorexia was associated with low self-esteem, personal alienation, interoceptive deficits, emotional dysregulation, and asceticism. Hierarchical multiple regression analysis indicated that difficulties with emotion regulation and ascetic tendencies were significant predictors of drunkorexia among adolescents.

CONCLUSIONS

Our findings suggest the importance for programs preventing drunkorexia to be focused on training adolescents in using more adaptive strategies to manage emotions and accepting both emotional and physical signals without feeling guilty or threatened.

LEVEL OF EVIDENCE

Level V, descriptive study.

Stress as an immunomodulator: liver X receptors maybe the answer

Stress is a reflex response, both psychological and physiological, of the body to a difficult situation that requires adaptation. Stress is at the intersection of the objective event and the subjective event. The physiological mechanisms involved in chronic stress are numerous and can contribute to a wide variety of disorders, in all systems including the immune system. Stress modifies the Th1/Th2 balance via the HPA axis and a set of immune mediators. This will make the body more vulnerable to external infections in a scientific way while others claim the opposite, stress could be considered immune stimulatory. The development of synthetic LXR ligands such as T0901317 and GW3965 as well as an understanding of the direct involvement of these receptors in the regulation of proopiomelanocortin (POMC) gene expression and indirectly by producing a variety of cytokines in a stressor response, will open in the near future new therapeutic methods against the undesirable effects of stress on the behavior of the immune system.

Adolescent patients with eating disorders and their parents: a study of self-image and outcome at an intensive outpatient program

PURPOSE

The main aim of this clinical study was to explore how adolescent patients with eating disorders and their parents report their perceived self-image, using Structural Analysis of Social Behavior (SASB), before and after treatment at an intensive outpatient program. Another aim was to relate the self-image of the young patients to the outcome measures body mass index (BMI) and Children's Global Assessment Scale (C-GAS) score.

METHODS

A total of 93 individuals (32 adolescents, 34 mothers, and 27 fathers) completed the SASB self-report questionnaire before and after family-based treatment combined with an individual approach at a child and youth psychiatry day care unit. The patients were also assessed using the C-GAS, and their BMI was calculated.

RESULTS

The self-image (SASB) of the adolescent patients was negative before treatment and changed to positive after treatment, especially regarding the clusters self-love (higher) and self-blame (lower). A positive correlation between change in self-love and in C-GAS score was found, which rose significantly. Increased self-love was an important factor, explaining a variance of 26 %. BMI also increased significantly, but without any correlation to change in SASB. The patients' fathers exhibited low on the cluster self-protection. Mothers' profiles were in line with a non-clinical group.

CONCLUSIONS

Results indicate that the self-image of adolescent patients change from negative to positive alongside with a mainly positive outcome of the ED after treatment. Low self-protection according to SASB among fathers suggests the need for greater focus on their involvement.

Explaining the pathway from familial and peer social support to disordered eating: Is body dissatisfaction the link for male and female adolescents?

OBJECTIVE

This study examined if familial and peer social support longitudinally predicted disordered eating for late adolescents in the transitional first year of college, and if body dissatisfaction mediated this relation. Gender differences between support types and disordered eating, and body dissatisfaction as a mediator, were also examined.

PARTICIPANTS/METHODS

651 late adolescent males and females (Mage=18.47) completed measures of social support at the end of the first semester of college and of disordered eating and body image approximately five months later, at the end of the first year.

RESULTS

Lower levels of familial social support prospectively predicted greater disordered eating, but not greater body dissatisfaction, and lower levels of peer social support prospectively predicted greater body dissatisfaction but not greater disordered eating, above and beyond the other type of social support type, prior levels of body dissatisfaction, disordered eating, and BMI. Body dissatisfaction did not mediate the relation between familial social support and disordered eating; however, it did significantly mediate the non-significant relation between peer social support and disordered eating, which was further moderated by gender.

CONCLUSION

These findings suggest that parental social support remains a significant predictor of disordered eating for late adolescents even after they transition to college, and has a stronger relation to disordered eating than peer support. In contrast, peer social support seems to be especially linked to feelings of body dissatisfaction and may be an avenue for intervention of this type of negative self-perception that is a risk factor for later disordered eating.

Eating Disorders and Associated Health Risks Among University Students

OBJECTIVE

To determine the prevalence of eating disorders among university students and its relationship to behavioral characteristics and substance use.

DESIGN

Cross-sectional study collected socioeconomic characteristics and behavioral risk.

SETTING

University of Upper Normandy, France.

PARTICIPANTS

University student volunteers.

PHENOMENON OF INTEREST

The Sick, Control, One stone, Fat, Food (SCOFF) screening test was used to identify subjects with eating disorders by a confidential questionnaire self-administered either online or on paper.

ANALYSIS

Multivariate logistic regression models with P < .05 considered significant.

RESULTS

A total of 3,457 students were included with a male-to-female ratio of 0.57. The prevalence of positive SCOFF screening was 20.5% among students. A positive relation between the positive SCOFF was observed with female gender (adjusted odds ratio [AOR], 2.98; 95% confidence interval [CI], 2.28-3.89; P < .001), stress (AOR, 1.10; 95% CI, 1.09-1.12; P < .001), depression (AOR, 8.62; 95% CI, 3.37-22.10; P < .001) alcohol abuse problems (AOR, 1.52; 95% CI, 1.20-1.95; P = .006), and risk of cyber-addiction (AOR, 5.09; 95% CI, 2.69-9.62; P < .001).

CONCLUSIONS AND IMPLICATIONS

Eating disorders are highly prevalent among university students in France and associated with other behavior risks, stress, and depression. It might prove necessary in the future to screen students with the SCOFF questionnaire upon entry to the university to inform student about the risk of eating disorders and advise them to consult with their general practitioner.

Stressful task increases drive for thinness and bulimia: a laboratory study

The scientific literature has suggested that stress undergirds the development of eating disorders (ED). Therefore, this study explored whether laboratory induced stress increases self-reported drive for thinness and bulimic symptoms measured via self-report. The relationship between control, perfectionism, stress, and cognition related to ED was examined using correlational methodology. Eighty-six participants completed an experimental task using a personal computer (PC). All individuals completed a battery of tests before and after the stressful task. Analyses showed a significant statistical increase in average scores on the drive for thinness and bulimia measured before and after a stressful task, and path analysis revealed two different cognitive models for the mechanism leading to drive for thinness and bulimia. These findings suggest that stress is an important factor in the development of the drive for thinness and bulimia.

Out of my real body: cognitive neuroscience meets eating disorders

Clinical psychology is starting to explain eating disorders (ED) as the outcome of the interaction among cognitive, socio-emotional and interpersonal elements. In particular two influential models—the revised cognitive-interpersonal maintenance model and the transdiagnostic cognitive behavioral theory—identified possible key predisposing and maintaining factors. These models, even if very influential and able to provide clear suggestions for therapy, still are not able to provide answers to several critical questions: why do not all the individuals with obsessive compulsive features, anxious avoidance or with a dysfunctional scheme for self-evaluation develop an ED? What is the role of the body experience in the etiology of these disorders? In this paper we suggest that the path to a meaningful answer requires the integration of these models with the recent outcomes of cognitive neuroscience. First, our bodily representations are not just a way to map an external space but the main tool we use to generate meaning, organize our experience, and shape our social identity. In particular, we will argue that our bodily experience evolves over time by integrating six different representations of the body characterized by specific pathologies—body schema (phantom limb), spatial body (unilateral hemi-neglect), active body (alien hand syndrome), personal body (autoscopic phenomena), objectified body (xenomelia) and body image (body dysmorphia). Second, these representations include either schematic (allocentric) or perceptual (egocentric) contents that interact within the working memory of the individual through the alignment between the retrieved contents from long-term memory and the ongoing egocentric contents from perception. In this view EDs may be the outcome of an impairment in the ability of updating a negative body representation stored in autobiographical memory (allocentric) with real-time sensorimotor and proprioceptive data (egocentric).

Emotional dysregulation and anxiety control in the psychopathological mechanism underlying drive for thinness

Emotional dysregulation is a process which consists in mitigating, intensifying, or maintaining a given emotion and is the trigger for some psychological disorders. Research has shown that an anxiety control plays an important role in emotional expression and regulation and, in addition, for anorexia nervosa (AN) and, more in general, in drive for thinness. Scientific literature suggests that in AN there is a core of emotional dysregulation and anxiety control. The aim of this study is to explore the roles of emotional dysregulation and anxiety control as independent or third variables in a mediational regression model related to drive for thinness. One hundred fifty-four clinical individuals with anorexia participated in the study and all completed a set of self-report questionnaires: eating disorders inventory version 3 (EDI-3), DERS, and the anxiety control questionnaire. The data confirmed a mediational model in which the relation between emotional dysregulation and drive for thinness is mediated by anxiety control. The current study partially supports a clinical model in which emotional dysregulation is a distal factor in eating disorders while the mediator variable anxiety control is a proximal factor in the psychopathological process underlying it.

Negative affective experiences in relation to stages of eating disorder recovery

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.

Prevalence and association of perceived stress, substance use and behavioral addictions: a cross-sectional study among university students in France, 2009-2011

BACKGROUND

University students face multiple stressors such as academic overload, constant pressure to succeed, competition with peers as well as concerns about the future. Stress should not be considered on its own, but should be associated with potential risk behaviors leading to onset of substance use and related problems heightened during the university period. The aim of this study was to determine the prevalence of main substance use and behavioral addictions among students in higher education in France and to examine the relationship with perceived stress.

METHODS

A self-administered questionnaire was filled out by university student volunteers from Upper Normandy (France) either by anonymous online questionnaire or by paper questionnaire. Data collected included socio-economic characteristics, Perceived Stress Scale (PSS), substance use (tobacco, alcohol, and cannabis) and hazardous behaviors: alcohol abuse problems, smoking, consumption of cannabis, eating disorders, and cyber addiction.

RESULTS

A total of 1876 students were included. Mean PSS score was 15.9 (standard deviation = 7.2). Highly stressed students (4th quartile) were compared with lesser stressed students (1st quartile). A positive relation was observed between female gender, regular smokers, alcohol abuse problems, risk of cyberaddiction and especially eating disorders (AOR = 5.45, 95% CI = 3.42-8.69), and increasing PSS score. PSS score however, was not significantly related to the curriculum, regular alcohol use, drunkenness or binge drinking even after additional controlling for use of other substances. We found a significant negative association between stress and practice of sport: students with the most physical activity were less likely to report perceived stress (4th quartile: AOR = 0.57, 95% CI = 0.39-0.80).

CONCLUSIONS

This cross-sectional study among university students in France revealed that perceived stress was associated not only with known risks such as alcohol misuse, but also with new risks such as eating disorders and cyber addiction. These results could help to develop preventive interventions focussing on these risk behaviors and subsequently improving stress coping capacity in this high-risk population.

Relationship of a desire of thinness and eating behavior among Japanese underweight female students

OBJECTIVE

We conducted a questionnaire survey among Japanese female students to explore the influence of a desire for thinness and dietary behaviors on the development of eating disorders.

METHODS

Self-reported measures of socio-demographic characteristics, body weight perception, height and weight, and dietary and exercise behavior were completed by 631 female university students at 6 universities in Kyoto, Japan.

RESULTS

Many students had a desire for thinness (underweight students, 51.7 %; normal-weight students, 88.8 %), whereas ideal weight and body mass index were lower in the students with a desire for thinness than the students without a desire for thinness, and were also lower in the underweight students than the normal-weight students. The eating attitude test (EAT-26) scores of underweight students with a desire for thinness were higher than those of the normal-weight students with a desire for thinness. As a result of a logistic regression analysis, underweight, desire for thinness, and experience with weight control were positively associated with eating problems. Further, the association of eating problems increased along with the increase in the number of factors (underweight, desire for thinness, and experience with weight control).

CONCLUSIONS

These results indicate that underweight females have strong associations with eating problems.

Self-esteem and social anxiety in an adolescent female eating disorder population: age and diagnostic effects

This study explored symptoms of social anxiety and multidimensional self-esteem in a clinical, adolescent female eating disorder population. Using self-report measures, data from 344 females revealed significant negative relationships between dimensions of self-esteem and social anxiety. A diagnostic difference emerged, with the restricting subgroup reporting significantly higher perceived physical appearance and global self-worth than those with binge/purge symptoms or bulimia nervosa. No significant age differences or age by diagnosis interaction effects emerged. These findings suggest that in clinical samples of adolescent eating disorders, self-esteem and social anxiety share a significant inverse relationship and seem to remain fairly constant across adolescence.

Understanding catastrophic worry in eating disorders: process and content characteristics

BACKGROUND AND OBJECTIVES

The majority of people with eating disorders (ED) experience high levels of comorbid anxiety and depression, yet the maintenance processes of these in ED remain largely unknown. Worry, a defining cognitive feature and important maintenance factor of anxiety, has not been well-studied amongst people with ED. This is the first study to explore both the process and content characteristics of catastrophic worry in ED.

METHODS

Twenty-nine patients with anorexia nervosa (AN), 15 patients with bulimia nervosa (BN) and 37 healthy controls (HC) completed measures assessing anxiety, depression, worry and eating disorder pathology. Catastrophic worry was assessed using the Catastrophizing Interview and catastrophic worry content was explored using qualitative Thematic Analysis.

RESULTS

Compared to HCs, ED groups had higher levels of anxiety, depression and worry and they generated a greater number of catastrophic worry steps. Worry was further found associated with depressive symptomatology in those with ED. Worry content for the ED groups included ED themes, but also themes reflecting broader inter and intrapersonal concerns.

LIMITATIONS

The degree to which worry is driven by depressive versus anxious symptomatology remains unclear. The current study does not include an anxious or depressed control group, and results should be considered in the light of relatively small samples sizes.

CONCLUSION

Findings indicate that interventions that target worry processes may be a useful adjunct to treatment for those ED patients with clinical worry levels.

The effects of avoidance coping and coping self-efficacy on eating disorder attitudes and behaviors: a stress-diathesis model

The present study employed a series of stress-diathesis models to examine whether avoidance coping and poor coping self-efficacy contribute to disordered eating attitudes and behaviors in a sample of college students. The sample included one hundred fifteen undergraduate students (28.7% male; 71.3% female). Participants completed self-report measures to assess daily stressors, coping style, coping self-efficacy, and eating disorder attitudes and behaviors. As predicted, among students with an avoidance coping style, those who reported more daily stressors exhibited higher eating disorder attitudes and behaviors than those with less daily hassles. Contrary to study hypothesis, number of daily hassles did not moderate the association between coping self-efficacy and eating disorder attitudes and behaviors. However, there was a significant main effect for coping self-efficacy, suggesting that students who lack confidence in their coping abilities are more likely to have problematic eating attitudes and behaviors, regardless of their level of daily stress. Clinically, results suggest that students who enter college with an avoidance coping style and poor coping self-efficacy may be at risk for disordered eating, particularly with the onset of associated stress. Teaching students active problem-focused coping skills to deal with daily hassles associated with college life, and providing opportunities for repeated practice to bolster self-efficacy, may help prevent and/or reduce disordered eating attitudes and behaviors.

Academic examination stress increases disordered eating symptomatology in female university students

BACKGROUND

It is well documented that stress and anxiety can affect eating behaviour and food intake in humans. The purpose of the current study was to explore the possible effect of academic examination stress on disordered eating attitudes, emotional eating, restraint eating, body image, anxiety levels and self-esteem in a group of female university students. The interrelationships of the above parameters were also examined.

METHODS

Sixty Greek female university students, 18-25 years old, have been recruited and completed, on two separate occasions: a) during an examination stress period, and b) during a control period, the following questionnaires: the Eating Attitudes Test (EAT-26), the Dutch Eating Behavior Questionnaire (DEBQ), the State-Trait Anxiety Inventory (STAI), the Rosenberg Self- Esteem Scale, the Body Image Pictorial Instrument Scale (COLLINS) and a specially designed General Background Questionnaire.

RESULTS

Subjects reported significantly higher levels of disordered eating attitudes (EAT-26, p=0.01), higher levels of anxiety (p=0.000) and lower levels of self-esteem (p=0.016) during the examination stress period compared to the control period. Disordered eating attitudes (EAT-26) were significantly positively correlated with emotional eating (p=0.04) and restrained eating (p=0.010) and negatively correlated with levels of self-esteem (p=0.05) and perceived desired body image (p=0.008) during the exam stress period. Finally, EAT-26 was significantly positively correlated with levels of anxiety in both study periods.

CONCLUSION

Academic examination stress seems to increase disordered eating symptomatology in female university students and is associated with lower levels of self-esteem, an important finding which warrants further investigation.

Illness perception in bulimia nervosa

The study was designed to extend our understanding of illness perceptions in patients with bulimia nervosa (BN). Seventy-eight participants with BN or BN-type Eating Disorder Not Otherwise Specified (EDNOS-BN) completed the Revised Illness Perception Questionnaire (IPQ-R) ( Moss-Morris et al., 2002 ). Clinical variables were also assessed. Participants experienced their ED as chronic, with serious consequences and high associated levels of anxiety and depression. The disorder was attributed primarily to psychological causes. The results indicate the perceived severity of BN, and high level of associated distress. These findings highlight the potential for targeting illness perceptions in treatment.

Correlates of disordered eating attitudes among male and female young talented dancers: findings from the UK centres for advanced training

Correlates of disordered eating attitudes were examined with a mixed-sex sample of 347 young talented dancers aged 10-18 years from all UK Centres for Advanced Training. Equal proportions of females (7.3%) and males (7.6%) were symptomatic for disordered eating but correlates differed: for females, self-evaluative perfectionism, waking up > twice/night and hours of non-dance physical activity were predictive while for males, only the combination of self-evaluative and conscientious perfectionism was significant. Differences between menstrual status groups were evident, with young dancers (pre-menarcheal/within first year of menarche) reporting the least disordered eating attitudes and those with dysfunctional menses reporting the most.

How to deal with sociocultural pressures in daily life: reflections of adolescent girls suffering from eating disorders

Adolescent girls with eating disorders experience unattainable and contradictory expectations in daily life, which create stress and negatively affect their self-evaluation. Disordered eating may function as a way of seeking control and consistency. In order to make progress in the understanding of eating disorders, the aim of this study was to describe how adolescent girls with eating disorders reflect upon ways of dealing with sociocultural pressures in daily life. Eighteen interviews with girls aged 15-19 years were analyzed using a phenomenographic approach. The results were summarized into three conceptions: "Striving to be oneself " (conception A) was described as the most desirable, but also the hardest. "Adapting to various situations" (conception B) was used without much reflection, as long as it worked, but when this way of dealing with everyday expectations was unsuccessful it was evaluated negatively. "Presenting oneself in a positive light" (conception C) was described negatively even when it was successful. Within these conceptions, the participants described various strategies that could be used more or less effectively depending on the circumstances. A common theme was their difficulties in finding a balance between trying harder to live up to perceived expectations from others on one hand, and trying to accept the situation as it was, without trying to change themselves or the situation, on the other hand. The participants believed that their eating disorder was partly a result of being unable to deal with sociocultural pressures in an effective way, and they experienced a conflict between societal values of being assertive and values of being interpersonally oriented. Implications for treatment are discussed.

The key to unlocking the virtual body: virtual reality in the treatment of obesity and eating disorders

Obesity and eating disorders are usually considered unrelated problems with different causes. However, various studies identify unhealthful weight-control behaviors (fasting, vomiting, or laxative abuse), induced by a negative experience of the body, as the common antecedents of both obesity and eating disorders. But how might negative body image--common to most adolescents, not only to medical patients--be behind the development of obesity and eating disorders? In this paper, I review the "allocentric lock theory" of negative body image as the possible antecedent of both obesity and eating disorders. Evidence from psychology and neuroscience indicates that our bodily experience involves the integration of different sensory inputs within two different reference frames: egocentric (first-person experience) and allocentric (third-person experience). Even though functional relations between these two frames are usually limited, they influence each other during the interaction between long- and short-term memory processes in spatial cognition. If this process is impaired either through exogenous (e.g., stress) or endogenous causes, the egocentric sensory inputs are unable to update the contents of the stored allocentric representation of the body. In other words, these patients are locked in an allocentric (observer view) negative image of their body, which their sensory inputs are no longer able to update even after a demanding diet and a significant weight loss. This article discusses the possible role of virtual reality in addressing this problem within an integrated treatment approach based on the allocentric lock theory.

A Reliability Generalization Study of the Frost Multidimensional Perfectionism Scale (F–MPS)

Perfectionism has been identified as a common concern among clients who seek counseling services. For more than 20 years, the Frost Multidimensional Perfectionism Scale (F–MPS) has been used extensively to measure the construct of individuals' perfectionism. The current study used reliability generalization to identify the average score reliability as well as variables explaining the variability of score reliability. Typical reliability across subscale scores ranged from .71 to .86 with the Doubt about Action subscale showing the least variability and the Organization subscale showing the most. In addition, sex, language, and standard deviation of the scale had statistically significant relations to reliability estimates.

Psychosocial characteristics in relation to disordered eating attitudes in greek adolescents

The study explores possible links between eating attitudes in Greek adolescents and certain psychosocial characteristics such as self-esteem, empathy and anxiety. A total of 202 students (109 boys and 93 girls), 15-18 years old, have been recruited. The following questionnaires were used: the Eating Attitudes Test (EAT-26), the State-Trait Anxiety Inventory, the Self-Perception Profile for Adolescents, the Multidimensional Body-Self-Questionnaire-Overweight Preoccupation and the Index of Empathy of Children and Adolescents. The EAT-26 revealed that 18.3% of the total sample of students (12.8% of boys and 24.7% of girls) reported having disordered eating attitudes. Adolescents with disordered eating attitudes had significantly higher levels of anxiety and scored less in self-reported physical appearance and romantic appeal. Empathy and global self-esteem did not differ significantly between the two groups. Adolescents with disordered eating attitudes have certain psychosocial characteristics which differentiate them from the students with healthier eating attitudes.

Binge-like eating in mice

OBJECTIVE

Given the lack of reliable murine model of binge-like eating, we tried to induce this pathological behavior in mice.

METHOD

We used an experimental protocol mimicking the etiological factors involved in the development of binge eating in humans, that is, food restriction, refeeding (R-R) in presence of high palatable food, and stress (S).

RESULTS

Mice subjected to at least three cycles of R-R plus S (forced swimming stress), showed a binge-like behavior evident as early as 4 h, persisting 24 h after stress application and not associated to depressive-like behavior. However, after the third R-R/S cycle, food intakes of mice returned to normal levels.

DISCUSSION

(i) at least three cycles of R-R plus S are required to promote abnormal eating in mice, (ii) this is not associated to depressive-like behaviors, and (iii) the enhanced pathological behavior showed a transient nature not persisting after the third R-R/S cycle.

Disordered eating attitudes in relation to body image and emotional intelligence in young women

BACKGROUND

A number of different psychological factors have been implicated in the multifactorial aetiology of disordered eating (DE) attitudes and behaviours; however, the possible role of emotional intelligence in DE symptomatology has not been thoroughly investigated in the past. The present study aimed to explore the possible differences in emotional intelligence, body image and anxiety levels in young females with DE attitudes and healthy controls.

METHODS

A total of 92 Greek female university students, 18-30 years old, were recruited. Subjects completed the following questionnaires: the Eating Attitudes Test (EAT-26), the Multidimensional Body-Self Questionnaire (MBRSQ), the State-Trait Anxiety Inventory (STAI) and the BarOn Emotional Intelligence Questionnaire (BarOn EQ-I).

RESULTS

The EAT-26 revealed that 23% of the subjects presented DE attitudes. Women in the DE attitudes group had lower levels of Emotional Intelligence (EI) in comparison to the control group, particularly in factors such as emotional self-awareness (P < 0.05), empathy (P < 0.05), interpersonal relationships (P < 0.001), stress management (P < 0.05) and happiness (P < 0.05). The MBRSQ has revealed significant differences between the two groups in terms of overweight preoccupation (P < 0.001) and illness orientation (P < 0.01). The DE attitudes group had higher anxiety scores (STAI), although the differences were not significant. Finally, anxiety levels (STAI) were significantly correlated with levels of EI (BarOn EQ-I) (P < 0.001).

CONCLUSIONS

The young women enrolled in the present study with DE attitudes, a potential precursor to eating disorders, appear to have significant differences in many psychometrical parameters of emotional intelligence, such as emotional self-awareness and interpersonal relationships, which is an important finding in terms of the prevention and management of DE, and warrants further investigation.

Disordered eating and weight changes after deployment: longitudinal assessment of a large US military cohort

The effect of military deployments to combat environments on disordered eating and weight changes is unknown. Using longitudinal data from Millennium Cohort Study participants who completed baseline (2001-2003) and follow-up (2004-2006) questionnaires (n=48,378), the authors investigated new-onset disordered eating and weight changes in a large military cohort. Multivariable logistic regression was used to compare these outcomes among those who deployed and reported combat exposures, those who deployed but did not report combat exposures, and those who did not deploy in support of the wars in Iraq and Afghanistan. Deployment was not significantly associated with new-onset disordered eating in women or men, after adjustment for baseline demographic, military, and behavioral characteristics. However, in subgroup comparison analyses of deployers, deployed women reporting combat exposures were 1.78 times more likely to report new-onset disordered eating (95% confidence interval: 1.02, 3.11) and 2.35 times more likely to lose 10% or more of their body weight compared with women who deployed but did not report combat exposures (95% confidence interval: 1.17, 4.70). Despite no significant overall association between deployment and disordered eating and weight changes, deployed women reporting combat exposures represent a subgroup at higher risk for developing eating problems and weight loss.

Low perception of control as a cognitive factor of eating disorders. Its independent effects on measures of eating disorders and its interactive effects with perfectionism and self-esteem

OBJECTIVE

There is a large body of research about perfectionism and low self-esteem in eating disorders (ED). However, little is known about the influence in ED of a distorted cognition in the domain of control: the perception of low control. The present study examined the main and interactive effects of concern over mistakes (an important dimension of perfectionism), self-esteem, and perception of control on drive for thinness, bulimia, and body dissatisfaction.

METHOD

Forty individuals with ED and 55 controls completed the Multidimensional Perfectionism Scale, the Anxiety Control Questionnaire, the Rosenberg self-esteem scale, and the three symptomatic scales of the Eating Disorder Inventory, which are drive for thinness, bulimia and body dissatisfaction. Multiple linear regression was used to test the hypothesis that perception of low control has a significant effect on the symptomatic scales of the EDI.

RESULTS

The ED group had significantly lower perception of control and self-esteem and higher concern over mistakes, drive for thinness, bulimia, and body dissatisfaction than the control group. Analysis of interactive effects suggested that a combination of a low perception of control and a low self-esteem seems to moderate the effects of concern over mistakes on drive for thinness, bulimia, and body dissatisfaction.

DISCUSSION

ED are associated with a tendency to worry about mistakes, a low sense of self-esteem, and a low perception of control over internal feelings and external events. Perception of control and self-esteem seems to moderate the predictive power of concern mistakes on symptoms of ED. The results suggest that a low perception of control is an important cognitive factor in ED.

The influence of stress on the relationship between cognitive variables and measures of eating disorders (in healthy female university students): a quasi-experimental study

OBJECTIVE

Perfectionism, poor self-esteem and stress have all been described as important risk factors for eating disorders. The purpose of this study was to assess whether a stressful situation is significantly correlated to and associated with significantly higher levels of perfectionism, stress, quantifiable measures of eating disorders, and with significantly lower levels of self-esteem in a non-clinical sample.

METHOD

Thirty-five female university students completed the Multidimensional Perfectionism Scale, the Rosenberg Self-Esteem Scale, the Perceived Stress Scale, and the Eating Disorder Inventory two times; once on an average university day and once on the day of an exam. Descriptive statistics and t-tests were calculated to verify whether a stressful situation was associated with a significant difference in levels of perfectionism, self-esteem, stress, and measures of eating disorders. Bivariate correlations were calculated for both the stress and non-stress situation, to observe how the dimensions of perfectionism, self-esteem, and stress were associated with measures of eating disorders.

RESULTS

During the stress situation, the study participants had, on average, significantly higher levels of concern over mistakes, body dissatisfaction, drive for thinness, and perceived stress. Bivariate correlations revealed that during the stress situation perceived stress, cognitive variables and measures of eating disorders showed significant correlations with each other that were absent in the non stress situation.

DISCUSSION

The results of the present study suggest that the dimensions of pathological perfectionism, low self-esteem, and perceived stress are related to an increase in dieting thoughts and dissatisfaction with body aspect in non-clinical women during a performance that could potentially challenge the perception of their self-esteem. The stressful situation can be interpreted as an experience of invalidation, which could explain the connection between cognitive constructs and behaviours related to eating disorders.

Lifetime family violence exposure is associated with current symptoms of eating disorders among both young men and women

This study examines (a) whether different forms of lifetime family violence exposure are associated with current eating disorder symptoms among young adults, (b) whether current symptoms of depression and anxiety both mediate these links, and (c) whether findings differ by gender. Participants were 319 university students aged 18-20 years (56% male). Independent of gender, both direct victimization by family violence and witnessing family violence were associated with eating disorder symptoms. Symptoms of depression and anxiety partially mediated these associations, and results did not vary by gender. Findings suggest that depression and anxiety may play a role in the development and maintenance of eating disorder symptoms subsequent to repeated incidents of family violence exposure.
