Assessing disordered eating behaviours and attitudes: Factor structure and measurement invariance of the Arabic version of the eating attitudes test (EAT-26) in Saudi Arabia

BACKGROUND

The factorial structure of the Eating Attitudes Test (EAT-26) has been found to be inconsistent across studies and samples. This study aimed to resolve inconsistencies in the factorial structure of the Arabic version of the EAT-26 by identifying the best-fitting model and test its measurement invariance across sexes and BMI categories in a large non-clinical Saudi sample.

METHODS

1,734 Saudi adults (Mage 26.88 and SD 9.13), predominantly female, completed an online survey. Several existing models were tested (e.g., original 26-item three-factor model, second order 26-item three-factor model, 20-item four-factor model, and 16-item four-factor model) using confirmatory factor analysis (CFA). Fit indices including the CFI, SRMR, and RMSEA were used to identify the best-fitting model for Arabic version of the EAT-26. Multi-group confirmatory factor analysis (MGCFA) was used to test measurement invariance.

RESULTS

The original three-factor model and two other common models demonstrated poor fit (e.g., CFI = 0.727; SRMR = 0.0911; RMSEA = 0.085 [90% CI 0.082-0.087] for the original three-factor model). Instead, a 16-item, four-factor structure [(Self-Perceptions of Body Weight), (Dieting), (Awareness of Food Contents), and (Food Preoccupation)] showed acceptable fit ([CFI = 0.904; SRMR = 0.0554; RMSEA = 0.073 [90% CI 0.068- 0.077]). Internal consistency was good (α and ω = 0.88), and measurement invariance was supported across sex (male and female) and BMI categories (underweight, normal weight, overweight, and obese).

CONCLUSIONS

These findings underscore the need for culturally relevant validation of the EAT-26 among Arabic-speaking populations, as the revised factorial structure diverged from previously established models. Future research should further examine this revised 16-item, four-factor structure in clinical settings.

A Reliability Generalization Meta-Analysis of the Eating Attitudes Test 26 (EAT-26) Scale

The Eating Attitudes Test 26 (EAT-26) scale is a well-established tool for assessing the risk of eating disorders. A reliability generalization meta-analysis was conducted to estimate the average reliability of the EAT-26 scale scores and how reliability estimates vary according to the composition and variability of samples, to identify study characteristics that can explain its variability, and to estimate the reliability induction rate. A literature search produced 14 articles involving 15 studies that met the inclusion criteria. For the total scores of the EAT-26 scale, pooled Cronbach's alpha was 0.85, with 95% confidence intervals of 0.81 and 0.88, a standard error (SE) of 0.02, and a standard score of (Z = 43.99). Moderator analysis showed that the language, age, or sex of the participants did not affect the overall results. By assessing the reliability of research findings, researchers can examine the consistency of results across studies, which can help identify sources of variability in the results.

Dysfunctional eating attitudes and behaviors among French elite athletes: the impact of psychological characteristics and the sporting calendar

Background

Research on sport psychology suggests that athletes are at risk of developing dysfunctional eating attitudes and behaviors (DEAB), however the origins of these behaviors remain largely unexplored. The present study aims to identify factors (i.e., personality traits, anxiety levels, eating attitudes and behaviors, the internalization of sport thinness norms, and resilience) associated with the development of DEAB among female endurance athletes, in training and competition.

Method

A longitudinal follow-up study was conducted among 14 elite female athletes who were tested daily, weekly, and quarterly over 12 months in 2022, for a total of 545 measures. Participants completed questionnaires assessing personality traits, anxiety levels, eating attitudes and behaviors, the internalization of sport thinness norms, and resilience. Descriptive statistics were calculated for all study data, and odds ratios were conducted to compare the variance of psychological factors and sporting factors depending on the level of DEAB and the sport period. Significance was set at p < 0.05.

Results

Overall, 28% of our sample of athletes were identified with DEAB. Among those with DEAB, scores for agreeableness, anxiety, and competitive anxiety were significantly higher, while scores for resilience were significantly lower than those without DEAB. During the competitive season, scores for self-regulatory eating attitudes and the internalization of thinness norms were significantly higher than during the training period.

Conclusion

Our results suggest a greater probability of DEAB among athletes who exhibit the trait of agreeableness, experience anxiety during competition, and lack resilience. The competitive season was also identified as a period conducive for developing DEAB compared with the training period. Based on these results our study suggests preventive measures that can be implemented with athletes displaying these traits, with a particular emphasis during the competitive phase.

Development of a visual-perceptual method to assess body image: A cross-cultural validation in Canadian and Spanish women

The objectives of this study were (a) to explore the preliminary cross-cultural validity of a visual-perceptual method to assess body image; (b) to examine potential differences and similarities in body image phenomena between women from two Western countries (i.e., Canada and Spain). 201 self-identified women participated in this cross-sectional study. Ideal, normal, and self-perceived body sizes were assessed using a visual-perceptual method, whereas body dissatisfaction was measured using both a visual-perceptual method and a questionnaire. Visual-perceptual body dissatisfaction was significantly correlated with questionnaire body dissatisfaction, suggesting a preliminary convergent validity between the two assessment methods. Women in both countries were dissatisfied with their bodies. Compared to their self-perceived body, all women chose a significantly thinner visual representation of their "normal" and ideal body. These results may suggest a shift towards the "thin" body as not only ideal, but also normative. This study provides the first evidence for the cross-cultural validity of a visual-perceptual body image assessment tool. The results of the current study confirm the presence of "normative discontent", and suggest more cross-country similarities than differences among women from these two Western societies.

Personal risk factors and types of sport associated with drive for thinness and drive for muscularity in NextGen athletes

Introduction

Professional and student-athletes are at risk of developing symptoms of eating disorders (ED), including drive for thinness and muscularity due to personal risk factors (e.g., low self-esteem) and sport-specific characteristics (e.g., sport requirements). However, limited studies have focused on ED symptoms among NextGen athletes (identified in Canada as élite or relève) who compete at the provincial, national, and international levels but are not yet part of national teams. As such, they have access to fewer financial resources and support from their sport federations, which can create additional stress for these athletes. The present study aimed to identify personal risk factors and types of sports associated with (a) drive for thinness and (b) drive for muscularity in NextGen athletes.

Methods

These athletes (n = 254) aged between 14 and 25 years old completed an online questionnaire. Perfectionism, self-esteem in sport, drive for thinness, and drive for muscularity were, respectively, assessed by the Multidimensional Inventory of Perfectionism in Sport, the Sport State Self-Esteem Scale, the Eating Attitude Test-26, and the Drive for Muscularity Scale. Other personal risk factor (e.g., athletic status) were measured using in-house questions. Each personal risk factor was included in two multiple linear regressions, respectively, to determine which factors were most associated with drive for thinness and drive for muscularity.

Results

Analyses revealed that perfectionist aspirations during training were linked to a stronger desire for thinness. In addition, not being in school or not having a job were also linked to a stronger desire for thinness. Several variables were found to be associated with a greater desire for muscularity: being a male athlete, playing team sport, weight category sport or endurance sport (as opposed to esthetic sport), having elite status, being less satisfied with one's current sporting performance and having higher perfectionist aspirations during training.

Discussion

This study offers initial insights into the factors influencing EDs among NextGen athletes, which provides a foundation for deeper exploration and the creation or modification of targeted interventions. These findings can guide sport organizations in creating guidelines and programs to better support the next generation of national athletes (e.g., create programs to help athletes maintain investments outside).

The progression and mechanisms of mental illness symptoms in university student-athletes during the COVID-19 pandemic

A few studies have examined mental illness symptoms in university student-athletes during the COVID-19 pandemic, but the limited use of longitudinal design limits the understanding of the progression of these symptoms and the mechanisms by which they developed. The present research aims to describe the trajectory of variation of mental illness symptoms (anxiety, depression, alcohol consumption disorders, and eating disorders) throughout the pandemic, to test causality between perceived stress and symptoms, and to identify individual characteristics (sociodemographic, perceived stress, and social support) influencing the trajectories of mental illness symptoms. On three occasions during the pandemic, 211 university student-athletes were surveyed. Latent growth models and random intercept crossed-lagged panel models were performed. Results indicate that anxiety and depressive symptoms significantly decreased throughout the COVID-19 pandemic while alcohol consumption disorder symptoms significantly increased and eating disorder symptoms did not change significantly. Second, perceived stress was a significant cause of anxiety and depressive symptoms during this pandemic. Conversely, eating disorder symptoms significantly predicted perceived stress. Finally, average perceived stress and average social support availability throughout the COVID-19 pandemic, and identifying as a visible minority, significantly predicted the trajectory of depressive symptoms, allowing for the identification of a sub-population at higher risk. Based on these findings, teaching stress management strategies should be an essential component of programs to prevent mental illness symptoms in university student-athletes. Reducing environmental stressors and their consequences among this population should also be prioritised.

Body image as a mediator in the relationship between psychotic experiences and later disordered eating: A 12-month longitudinal study in high school adolescents

BACKGROUND

The relationship between psychosis and disordered eating remains a challenging area of research to which little interest was paid. Using longitudinal data, we aimed to explore the hypothesis that the pathways from psychotic experiences (PEs) to disordered eating (DE) and body-mass index (BMI) are mediated by body-image disturbances.

METHODS

A prospective longitudinal study was performed. High-school students (N = 510, 61.2% females, mean age of 16.05 ± 1.01 years) were asked to complete three scheduled assessments (Baseline, 6 months, and 12 months).

RESULTS

Two body image components, that is, Overweight Preoccupation and Body Area Satisfaction, mediated the prospective association between baseline PEs and DE 12 months later. Direct effects were significant. After accounting for indirect effects through more severe body image concerns at 6 months, higher baseline PEs were significantly associated with greater DE at 12 months. Baseline PEs and 6-month body image explained a significant proportion of variance in 12-month DE. However, we did not find evidence of a direct prospective association between PEs and BMI.

CONCLUSION

This study is the first to assess the mediating role of body image between PEs and DE. Findings offer promising new avenues for early intervention to help mitigate the effects of PEs on DE in adolescents.

Relation between orthorexia nervosa and healthy orthorexia: A latent profile analysis

Orthorexic eating behaviors can be conceptualized as a bidimensional construct encompassing an orthorexia nervosa dimension (ON) and a healthy orthorexia dimension (HO). Although variable-centered studies showed that ON and HO are distinguishable orthorexic eating behaviors, the evidence of whether they can co-occur or be distinct in subgroups of individuals is still limited. The present study aimed to address previous person-centered studies' limitations by examining profiles of ON and HO among a convenience sample of 251 French-speaking Canadian adults (85.7% women; Mage = 33.56). Profile membership was examined as function of participants characteristics such as age, gender, body mass index, frequency of physical activity and sports and vegetarianism. The relation between profile membership, intuitive eating and disordered eating attitudes and behaviors was also assessed. Latent profile analysis (LPA) were used to estimate profiles of ON and HO. Results from LPA did not provide support for the distinguishability of ON and HO. Indeed, they revealed the presence of two profiles showing co-occurring levels of ON and HO that only differed quantitatively: low (68.9% of the sample; low levels of ON and HO) or moderate orthorexic eating behaviors (31.1%; moderate levels of ON and HO). Participants who declared being vegetarian and being more frequently involved in physical activities and sports were more likely to belong to the moderate orthorexic eating behaviors' profile. Finally, participants from the moderate orthorexic eating behaviors' profile showed higher levels of disordered eating attitudes and behaviors, whereas those from the low orthorexic eating behaviors' profile showed higher levels of intuitive eating. Findings from the present study question the distinguishability of ON and HO dimensions. They also suggest that, similarly to ON, HO is also related to higher eating and lifestyle preoccupations.

Muscle dysmorphia from an addictive perspective: Validation of the Addiction to Body Image Inventory (ABII)

OBJECTIVES

Muscle dysmorphia (MD) is a disorder affecting mainly men and is characterized by significant dissatisfaction with muscles. The idea that MD could represent an addiction has been theoretically discussed, but no empirical data are available. Based on Foster et al. (2015) framework, the Addiction to Body Image Inventory (ABII) was developed. This study aims to validate the ABII and to evaluate its capacity to capture MD severity.

METHODS

A first community sample of 466 participants was recruited and completed the ABII and questionnaires on MD and body esteem. A second sample of 47 men at risk of MD was recruited mostly in gyms and completed the ABII and questionnaires on MD, eating and psychological symptoms.

RESULTS

With the community sample, the results showed that the ABII had a valid factorial structure, good internal consistency, and good convergent validity. With the sample of men at risk of MD, the results showed that the ABII had good convergent validity with MD and eating symptoms but not with psychological symptoms. The results of a regression model showed that the ABII explained 12% of the MD variance.

CONCLUSIONS

This study brings the first measure of addiction to body image and suggests that MD must be understood as a complex phenomenon including eating symptoms and addictive tendencies.

Development and validation of the Symptomatic Transdiagnostic Test (S2T)

INTRODUCTION

The categorical approach in psychiatry has received many criticisms. Modern research tends to develop a transdiagnostic approach. However, transdiagnostic works lack an overall understanding and focus mainly on anxiety and depression. The aim of the present study was to develop an easy to use tool to evaluate multiple dimensions opening the way for further research in the transdiagnostic approach. This will allow researchers to quickly assess the efficacy of psychotherapeutic interventions on multiple psychopathological dimensions.

METHOD

First, we identified the main symptoms of psychopathology in a sample of mental healthcare workers. Second, we developed the Symptomatic Transdiagnostic Test (S2T) to assess the main symptoms of psychopathology. Third, we evaluated its psychometric properties (exploratory and confirmatory factor analysis, internal consistency) in three non-clinical samples and one clinical sample.

RESULTS

The 66-item S2T included eleven factors referring to: i) negative thoughts and mood; ii) psycho-traumatic and maladaptive symptoms; iii) addiction symptoms; iv) disturbed eating behavior; v) disturbed perception and behavior; vi) panic and agoraphobia; vii) emotional lability; viii) dejection; ix) neurodevelopmental manifestations; x) anxiety and xi) psychic hyperactivity. We found a high internal consistency for the general scale (α=0.96) and the subscales. We found a good concurrent validity. As expected, we found higher levels of symptoms within the clinical population as compared to the non-clinical samples, except for addiction symptoms and disrupted eating behavior. We found negative associations between the symptomatic dimensions and psychological skills.

CONCLUSION

The S2T is a relevant tool for clinicians and researchers to assess the psychopathological profile. The main psychopathological symptoms are negatively related to the psychological skills.

Relationship between Fear of COVID-19, Intolerance of Uncertainty, and Coping Strategies on University Students' Mental Health

BACKGROUND

the mental health of students was particularly affected by the COVID-19 pandemic. The present study therefore examined the relationships between anxiety and depressive symptoms, eating-related problems, coping, fear of COVID-19, and intolerance of uncertainty.

METHODS

2139 French students of 54 universities were recruited in the different regions of France during a French lockdown (between 21 April and 3 May 2021). Six variables were measured: fear of COVID-19, intolerance of uncertainty, coping, anxiety and depressive symptoms, and eating-related problems. To explore the directions of the relationships between our variables of interest, we calculated a directed acyclic graph.

RESULTS

our data highlighted the central roles of intolerance of uncertainty in students' anxiety and depressive symptoms, and the direct role of prospective intolerance of uncertainty on eating-related problems.

CONCLUSIONS

these findings indicate that intolerance of uncertainty should be targeted by interventions designed to help students with high levels of anxiety, depressive symptoms, and/or eating-related problems.

Body image concerns across different sports and sporting levels: A systematic review and meta-analysis

Mixed findings exist regarding whether athletes have different levels of body image concerns to non-athletes. Such body image concerns have not been reviewed recently, meaning that new findings need to be incorporated into our understanding of the adult sporting population. This systematic review and meta-analysis aimed first to characterise body image in adult athletes versus non-athletes, and second to explore whether specific sub-groups of athletes report different body image concerns. Impact of gender and competition level were considered. A systematic search identified 21 relevant papers, mostly rated moderate quality. Following a narrative review, a meta-analysis was conducted to quantify the outcomes. While the narrative synthesis indicated possible differences between types of sport, the meta-analysis demonstrated that athletes in general reported lower body image concerns than non-athletes. In general, athletes had a better body image than non-athletes, with no reliable differences between different type of sport. A combination of prevention and intervention strategies might assist athletes in focusing on the benefits to their body image without encouraging restriction/compensation or overeating. Future research should define comparison groups clearly, along with attending to training background/intensity, external pressures, gender and gender identity.

Association between family functioning and psychotic transition in ultra-high risk adolescents and young adults

Background

Psychotic transition (PT) is a crucial stage in schizophrenia. The Comprehensive Assessment of At-Risk Mental States (CAARMS) scale can be used to identify individuals at ultra-high risk (UHR) for psychosis and to evaluate their risk of PT. Many environmental and genetic factors have been identified as contributing to the development and decompensation of schizophrenia. This study aimed to determine if the quality of family functioning is associated with PT risk in UHR individuals aged between 11 and 25 years after 1 year of follow-up.

Methods

From January to November 2017, 45 patients aged 12 to 25 consulting for psychiatric reasons were included. Twenty-six were classified as UHR of PT at the CAARMS. Family functioning was assessed by the Family Assessment Device-Global Functioning (FAD-GF). Thirty-seven of these patients (30% men, mean age 16 ± 2.5) were reassessed at 8-14 months of recruitment. Survival analysis was used to examine the impact of family functioning on PT risk.

Results

A total of 40% of UHR patients were classified as psychotic at reassessment. Survival analysis showed that better family functioning is a significant protective factor for PT in this population.

Discussion

This result suggests that the global family functioning has an impact at 1 year on the risk of PT in the population of adolescents and young adults who consult the hospital for psychiatric reasons. A family intervention may be effective in reducing PT risk in this population and should be considered as a potential therapeutic option.

Food avoidance in anorexia nervosa: associated and predicting factors

PURPOSE

Qualitative food avoidance is a significant issue in patients with anorexia nervosa (AN) and restoring diet diversity is an important part of the treatment process. We aimed to identify clinical factors which drive food avoidance and predict its maintenance in patients with AN.

METHODS

In this multicentre longitudinal study, 130 female outpatients with AN were assessed before and after 4 months of care in clinical centres specialized in AN. We assessed levels of avoidance of 16 food items, as well as body mass index (BMI), eating disorder severity, symptoms of depression and anxiety, emotional state, daily-life functioning, and body image perception.

RESULTS

We found that qualitative food avoidance was associated with the clinical severity of AN, anxiety and mood dimensions, and BMI- and body image-related factors. A younger age at onset predicted the maintenance of food avoidance after 4 months of treatment. Additional exploratory analyses suggested that anxiety and negative affect caused food avoidance more than the opposite.

CONCLUSION

Qualitative food avoidance can be an indicator of illness severity. During treatment, focusing on reducing anxiety and negative affect may be a way to indirectly reduce food avoidance and restore diet diversity.

Development of the Transdiagnostic Skills Scale (T2S)

INTRODUCTION

Psychotherapy has proved its efficacy for treating a wide range of psychological disorders. Most types of psychotherapy have been developed to treat specific disorders and validated through controlled-randomized trials. In recent years, researchers have developed a new way to conceptualize patients' difficulties, focusing on processes instead of diagnoses. However, there is no simple scale that evaluates transdiagnostic processes, and the development of such a tool is thus the aim of this study.

METHOD

We identified 12 processes that can be targeted in cognitive behavior therapy and created the Transdiagnostic Skills Scale (T2S) to evaluate them. We measured its internal consistency, factor structure and convergent validity in clinical and non-clinical samples.

RESULTS

We found a 6-factor structure composed of emotion regulation, behavioral activation/planning, emotional identification, assertiveness, problem solving and emotional confrontation. The T2S has high internal consistency (Cronbach's alpha = 0.95). We found negative associations between skills and symptoms of anxiety, depression and eating disorders. We found no association between these processes and symptoms of either alcohol or cannabis use disorder.

CONCLUSIONS

The T2S is a useful and valid tool to identify the skills that clinicians should work on with their patients. It offers a complementary way to understand patients' difficulties when categorical assessment is complicated.

Psychometric properties of the Teruel Orthorexia Scale (TOS) among a French-Canadian adult sample

BACKGROUND

Psychometric properties of the Teruel Orthorexia Scale (TOS) have been examined in several languages (Arabic, English, Portuguese, Spanish, and Turkish), but not in French.

PURPOSE

The objective was to examine the psychometric properties of the TOS among a French-Canadian adult sample.

METHODS

Participants were 296 French-speaking Canadian adults (M = 34.2 years, SD = 11.9, 85.1% women). They completed the TOS alongside with several other measures (e.g., alcoholic consumption, cigarette smoking, disturbed eating attitudes and behaviors, frequency of physical activities, intuitive eating, vegetarian diet, and negative affect).

RESULTS

The results supported the a priori two-factor representation (orthorexia nervosa and healthy orthorexia) of the French version of the TOS and provided further support for the superiority of an exploratory structural equation modeling approach, relative to a confirmatory factor analytic approach. Furthermore, the results supported no differential item functioning as a function of respondents' characteristics (age, body mass index, diagnosis of eating disorders, frequency of physical activities, gender, and vegetarian diet). Latent mean differences were found in healthy orthorexia and orthorexia nervosa factors as a function of respondents' characteristics. Finally, significant correlations were found between TOS factors and convergent measures (alcohol consumption, cigarette smoking, disturbed eating attitudes and behaviors, intuitive eating, and negative affect).

CONCLUSION

The present study confirmed that the French version of the TOS has satisfactory psychometric properties (i.e., factor validity and reliability, no differential item functioning, and convergent validity).

Symptoms of mental illness among university student-athletes during the second wave of the COVID-19 pandemic lockdown in Canada

The COVID-19 pandemic lockdown disrupted the university sports season and had negative consequences on the academic and personal life of university student-athletes, resulting in several psychological challenges. The goal of this study is to document the symptoms of mental illness among university student-athletes during the second wave of the COVID-19 pandemic lockdown in Canada. It aims to (a) assess the prevalence of mental illness symptoms (anxiety, depression, disordered eating, and dangerous drinking) among university student-athletes and (b) identify which sociodemographic and sports characteristics, pandemic impacts, and levels of perceived stress most influence these symptoms. A total of 424 university student-athletes completed an online survey, which included questions on mental illness and the impact of the pandemic lockdown. The results revealed a notable prevalence of the symptoms of mental illness; depressive symptoms are reported by 37.9% of the participants, anxiety symptoms by 24.9%, dangerous drinking symptoms by 10.1%, and disordered eating by 8.6%. In addition, being female [OR = 0.56, 95% CI (0.33, 0.95)] or a member of a visible minority group [OR = 2.63, 95% CI (1.02, 6.78)] are significantly associated with the presence of depressive symptoms. Low academic motivation has a significant negative influence on the presence of depressive [OR = 3.37, 95% CI (1.82, 6.25)] and anxiety symptoms [OR = 2.75, 95% CI (1.35, 5.62)]. However, the presence of perceived stress was strongly associated with depressive [OR = 7.07, 95% CI (3.26, 15.35)], anxiety [OR = 6.51, 95% CI (3.30, 12.84)], and dangerous drinking symptoms [OR = 5.74, 95% CI (2.51, 13.14)]. This study advocates for specific mental illness prevention and treatment resources tailored to the unique needs of university student-athletes. Accordingly, partnerships and practical interventions to support university student-athletes' mental health are presented.

The Self-Regulation of Eating Attitudes in Sport Scale: Defining an Optimal Regulation Zone

This study examines the hypothesis of a Zone of Optimal Regulation of Eating Attitudes in Sport (ZOREAS). The ZOREAS refers to a band, or zone within which athletes are most likely to optimize eating attitude regulation which should be associated with a low level of disordered eating. Scores outside this zone indicate a risk factor for eating disorders. One hundred and eleven volunteer athletes were recruited. Two variables were assessed: self-regulation of eating in sport, and eating attitudes and behaviors, measured with the French Self-Regulatory Eating Attitude in Sports Scale (SREASS), and the French version of the Eating Attitudes Test (EAT), respectively. Correlational analyses and an ANOVA were run. As expected, we observed a negative relationship between scores for the self-regulation of eating, and disordered eating attitudes in the sports context. To better-determine the ZOREAS, we ran a one-way ANOVA, which was significant for disordered eating attitudes. The plot of the interaction confirmed three trends: a high level of disordered eating attitudes (EAT scores over 20) is associated with a high level of self-regulation of eating attitudes (SREASS scores over 24); a medium level of disordered eating attitudes is associated with a low level of self-regulation of eating attitudes (SREASS scores under 19); a low level of disordered eating attitudes is associated with a medium level of self-regulation of eating attitudes (SREASS scores between 19 and 24). Thus, the ZOREAS was determined to be SREASS scores within the range 19–24. The ZOREAS may be useful to sports psychology practitioners who work with athletes.

Promoting Physical Activity Among University Students During the COVID-19 Pandemic: Protocol for a Randomized Controlled Trial

Background

Since the beginning of the COVID-19 pandemic, sanitary context and e-learning have greatly modified student lifestyles and led to deteriorations in their mental health. An increase in anxiety and depressive symptoms and sedentary behaviors, reduction in physical activity, and a stronger tendency to move toward unhealthy diet have been demonstrated. This finding highlights the need for innovative interventions to promote healthy lifestyle among students.

Objective

This research protocol aims to evaluate the effects of an intervention program on the lifestyle and psychological state of students.

Methods

Students from University of Nîmes were recruited and randomly assigned to 1 of 2 following conditions: an intervention group and a control group. Participants in the intervention group were engaged in an 8-week physical activity program. Prior to the start of the program, design-based innovative workshops were conducted with participants to ensure that the program was co-constructed by the users and met their specific needs. Students in the control group did not receive any intervention. For each group, measures of physical activity, sedentary time, anthropometric data, sleep, physical condition, and psychological variables (eg, anxiety, depression, motivation, body appreciation, perceived control, well-being) were conducted at baseline and 9 weeks later.

Results

A total of 110 participants were initially included. Reporting of the results is projected for the spring of 2022.

Conclusions

It is anticipated that this innovative intervention co-constructed by pairs will promote a healthier lifestyle and psychological health in students. There is every reason to believe that a mobilized co-construction approach is a promising strategy to limit unhealthy habits and promote physical activity while increasing motivation. The development and evaluation of interventions to address the specific needs of university students is essential and could be transferred to other vulnerable populations such as people with chronic diseases or older people.

Translation and validation of the Child Three-Factor Eating Questionnaire (CTFEQr17) in French-speaking Canadian children and adolescents

OBJECTIVE

To translate and validate the Child Three-Factor Eating Questionnaire (CTFEQr17), assessing cognitive restraint (CR), uncontrolled eating (UE) and emotional eating (EE), among French-speaking Canadian young individuals.

DESIGN

Phase 1 comprised a translation and the evaluation of the comprehension of the questionnaire. Phase 2 comprised a confirmatory factor analysis (CFA), the evaluation of internal consistency (Cronbach's α), test-retest reliability (intra-class correlation coefficients (ICC)) and construct validity, including correlations among the CTFEQr17 and Eating Attitudes Test (EAT-26), anthropometrics, dietary intake and diet quality.

SETTING

Primary and secondary schools, Québec City, Canada.

PARTICIPANTS

Phases 1 and 2 included 20 (40 % boys, mean age 11·5 (sd 2·4) years) and 145 (48 % boys, mean age 11·0 (sd 1·9) years) participants, respectively.

RESULTS

Phase 1 resulted in the questionnaire to be used in Phase 2. In Phase 2, the CFA revealed that the seventeen item, three-factor model (CTFEQr17) provided an excellent fit. Internal consistency was good (Cronbach's α: 0·81-0·90). Test-retest reliability was moderate to good (ICC = 0·59, (95 % CI 0·48, 0·70), ICC = 0·78, (95 % CI 0·70, 0·84), ICC = 0·50, (95 % CI 0·38, 0·62) for CR, UE and EE, respectively). CR correlated with EAT-26 score (r = 0·43, P < 0·0001). UE and EE correlated negatively with BMI Z-scores (r = -0;·26, P = 0·003; r = -0;·19, P = 0·03, respectively). CR correlated with the proportion of energy intake from protein and diet quality (r = 0·18, P = 0·04; r = 0·20, P = 0·02, respectively).

CONCLUSION

The CTFEQr17 is suitable to use among French-speaking Canadian young individuals.

Eating Behaviors Among Male Bodybuilders and Runners: Application of the Trans-Contextual Model of Motivation

This article focuses on two popular sports that can put male athletes at risk of developing an eating disorder: bodybuilding and running. Bodybuilders concentrate on gaining muscle mass and runners on leaning body mass. Based on the trans-contextual model of motivation, this study aimed to better understand the psychological mechanisms underlying eating disorders in these athletes. In all, 272 male bodybuilders and 217 male runners completed measures of sport motivation, theory of planned behavior variables (i.e., attitude, subjective norm, perceived behavioral control, and intention to gain muscle mass/lean body mass), and eating disorders (dieting, control, and bulimia behaviors). The results revealed satisfactory fit indices for both samples. Autonomous and controlled motivations for sport were positively directly and indirectly related to eating disorders in these athletes. This motivational mechanism needs more in-depth investigation, and motivational profiles might help distinguish athletes with and without eating disorders.

Personality profiles in young adults with orthorexic eating behaviors

PURPOSE

Orthorexia nervosa (ON), defined as an excessive preoccupation with healthy eating, has gained more interest in the literature over these past few years. However, little is known about its risk and protective factors, in particular with regards to personality.

METHODS

A total of 3235 college students (10.32% men, 89.67% women) with a mean age of 21.13 (SD = 2.23) answered self-administered questionnaires assessing ON, psychopathological symptoms, and personality disorders including schizotypal, borderline, paranoid, obsessive-compulsive, and narcissistic personality. A subsample of 106 participants (91.51% women, mean age = 20.91, SD = 2.31) was selected based on the DOS cutoff score, and was then considered as the "orthorexic subsample".

RESULTS

Hierarchical cluster analysis was performed in the orthorexic subsample and led to the identification of four groups: 1-a cluster with a low level of traits (L); 2-a cluster with moderate traits and low narcissistic traits (MD); 3-a cluster with a low level of traits and moderate narcissistic traits (MN); 4-a cluster with high paranoid and narcissistic traits (PN) and a moderate level of schizotypal and borderline traits. Levels of anxiety, obsessional-compulsive, and depressive symptoms were higher in the PN and MD clusters than in the L and MN clusters. Social phobia was higher and self-esteem lower in the MD cluster and hypochondriasis was higher in the PN and MN clusters.

CONCLUSIONS

This study suggests that ON can be associated with different personality profiles, some of them displaying significant psychopathological levels. It also emphasizes the importance of taking into account personality disorder traits of young adults with orthorexic eating behaviors.

Psychometric evaluation of the French version of the Düsseldorfer Orthorexia Skala (DOS) and prevalence of orthorexia nervosa among university students

PURPOSE

This study aimed at obtaining a French version of the DOS (F-DOS) and evaluating its psychometric properties in a sample of university students, then assessing the prevalence of orthorexic eating behavior among the participants.

METHODS

The F-DOS was obtained using back translation, and then administered to 3235 university students (10.32% men, 89.67% women) with a mean age of 21.13 (SD = 2.23). The Eating Habits Questionnaire and Eating Attitudes Test were used to assess convergent and divergent validities, respectively. Confirmatory factor analysis was performed to explore the factor structure.

RESULTS

Ordinal ⍵ of F-DOS was 0.87, indicating very good internal consistency. F-DOS and EHQ total scores were strongly correlated (r_s = 0.74, p < 0.001), indicating very good construct validity. Factor analysis revealed a well-fitted one-factor model. Regarding Orthorexia Nervosa (ON) prevalence, according to DOS cut-off score, 3.28% of participants could be considered having ON, while an additional 11.31% could be at risk of developing ON.

CONCLUSIONS

The F-DOS appears to be a valid and reliable instrument to assess orthorexic eating behavior. ON prevalence in college students appeared similar to Germany and lower than in the US.

Is the Severity of the Clinical Expression of Anorexia Nervosa Influenced by an Anxiety, Depressive, or Obsessive-Compulsive Comorbidity Over a Lifetime?

Purpose: The relationship between anxiety or depressive comorbidities, their chronology of onset, and the severity of anorexia nervosa (AN) is not well-studied. We hypothesize that the existence of a comorbidity, particularly before the onset of AN, is associated with greater severity of AN. Methods: One hundred seventy-seven subjects were assessed. The prevalence of major depressive disorder (MDD), obsessive-compulsive disorder (OCD), generalized anxiety disorder (GAD), and social phobia (SP) as well as their chronology of onset were studied. The assessment criteria of AN severity were the overall clinical condition, body mass index (BMI) on admission, lowest BMI, intensity of the eating symptoms, age at the onset of AN, illness duration, number of hospitalizations, and quality of life. Results: Patients with AN had the greatest clinical severity when they had a comorbid disorder over their lifetime, such as MDD, GAD, or SP. These comorbidities along with OCD were associated with a higher level of eating symptoms and a more altered quality of life. A profile of maximum severity was associated with a higher prevalence of MDD and GAD. Concerning the chronology of onset, the age at the start of AN was later in cases of MDD or GAD prior to AN. Conclusion: There seems to be an association between severity of AN and both MDD and GAD. The chronology of onset of the comorbidity did not seem to be associated with the severity.

Estimated Prevalence and Care Pathway of Feeding and Eating Disorders in a French Pediatric Population

Feeding and Eating Disorders (FED) are mostly described in infants and adolescents but are less well-known in children. Information on the prevalence of FED in the general pediatric population is still limited. The aim of this study was to estimate the prevalence and the care pathway of FED in a population aged 0-18 years old, using the Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 classification. Two physicians interviewed 401 families using a questionnaire including demographics, BMI, dietary behavior data, and age-appropriate screening tools. Qualitative and quantitative variables were compared using the Chi² test and Student's t-test, respectively. After a headcount adjustment based on the French population by age group, the estimated prevalence rate was 3% [95%CI (1.7-5.1)] for Avoidant and Restrictive Food Intake Disorder (ARFID), and 9.7% [95%CI (7.2-13.0)] for Unspecified FED (UFED), which included other restrictive and compulsive FED. The median age for ARFID was 4.8 years (0.8-9 years), and 7.5 years (0.6-17 years) for UFED. The interviews did not identify cases of anorexia, bulimia, binge eating disorder, other specified FED, pica or rumination. Only 15.2% of children with an FED were receiving medical care. The development of validated pediatric screening tools, as well as the training of health professionals in children FED is necessary.

Evaluation of cognitive impairment in a French sample of patients with restrictive anorexia nervosa: two distinct profiles emerged with differences in impaired functions and psychopathological symptoms

PURPOSE

The cognitive profiles of patients suffering from anorexia nervosa (AN) are currently explored as potential facilitating and/or maintenance factors. Specific data in restrictive AN (AN-R) remain contradictory. This study focused on women with AN-R to evaluate their cognitive functions to develop a more specific cognitive remediation program.

METHODS

Female patients older than 15 years who were suffering from AN-R were recruited in a specialized unit for eating disorder management. Female healthy control (HC) participants were recruited who were matched with AN patients on age. All participants completed a cognitive evaluation (premorbid intelligence quotient (IQ), planning, information processing speed, cognitive flexibility) and a clinical evaluation (impulsivity, anxiety, depression).

RESULTS

A total of 122 participants were included. Patients suffering from AN-R had significant impairment in information processing speed and planning. Patients exhibited significantly better cognitive flexibility than did the HC group when adjustments were made for other cognitive functions and impulsivity. Two distinct subgroups of patients were identified. The first subgroup had more marked cognitive impairment and fewer psychopathological symptoms than did the second subgroup of patients and the HC group.

CONCLUSION

Our results highlight cognitive impairment in patients with AN who had normal premorbid IQ. Two distinct profiles emerge. In clinical practice, these results open up perspectives for the development of more specific cognitive remediation programs (one specific program for cold cognitions and another specific program targeting emotions and hot cognitions). These results warrant confirmation by larger studies with a more specific evaluation of the impact of emotional status. Trial registration NTC02381639, Date of registration. March 6, 2015.

Increased cognitive flexibility mediates the improvement of eating disorders symptoms, depressive symptoms and level of daily life functioning in patients with anorexia nervosa treated in specialised centres

OBJECTIVE

Poor cognitive flexibility has been highlighted in patients with anorexia nervosa (AN), contributing to the development and maintenance of symptoms. The aim of the present study is to investigate how enhanced cognitive flexibility is involved in treatment outcomes in patients with AN.

METHOD

One hundred thirty female out-patients treated for AN have been assessed at baseline and after 4 months of treatment. Path analyses were used to investigate the mediating role of cognitive flexibility, measured through the Brixton test, on a wide range of outcomes: body mass index, eating disorder symptoms, daily life functioning, anxiety, depression, emotions, self-rated silhouette.

RESULTS

Cognitive flexibility was improved during treatment, and enhanced cognitive flexibility explains a significant part of level of the improvement in daily life functioning (26%), reduction of eating disorder symptoms (18%) and reduction of depressive symptoms (17%). Others outcomes were also improved, but these improvements were not mediated by cognitive flexibility.

CONCLUSIONS

Results suggest that enhancing cognitive flexibility could help reduce rigid cognitive and behavioural patterns involved in AN, thus improving everyday functioning and clinical severity. Further studies combining different types of cognitive flexibility evaluation as well as neuroimaging may be necessary to better establish which of its aspects are involved in patients' improvement.

Nutritional status and anxious and depressive symptoms in anorexia nervosa: a prospective study

The interweaving of malnutrition and symptoms of anxiety and depression in anorexia Nervosa (AN) is mentioned without any consensus regarding the course of anxious-depressive symptoms in relation to nutritional status in the course of treatment of patients with AN. The objectives of the current study in a large sample of AN inpatients were to assess the relationships between anxiety and depression symptoms and nutritional status both over the course of inpatient treatment and at discharge. 222 consecutive inpatients with AN (DSM-IV TR) were assessed (entrance and discharge) for duration of illness, psychiatric treatments, sociodemographic data and with psychometric scales for different psychopathological symptoms [depressive (BDI), anxiety and depressive (HAD scale), obsessive-compulsive (MOCI) and social phobia (LSAS fear score)]. Nutritional status was assessed with Body Mass Index (BMI) and body composition by bioelectrical impedance. The Fat free mass index [FFMI = FFM (kg)/height (m²)] was considered for the analysis. Two models were developed where the dependent variables were each psychopathological score at discharge (BDI, HAD anxiety, MOCI, and LSAS fear) in the cross-sectional model, and their variation in the longitudinal model (where a positive score reflected symptom decrease at discharge). A fixed set of predictors, defined on presumed clinical and statistical relevance (FFMI in the cross-sectional model and Variation of FFMI in the longitudinal model), were considered in each model, without any model selection procedure. This is the first study to confirm a positive relationship between the course of eating disorder symptoms and that of anxious-depressive symptoms during inpatient treatment of AN even after adjustment on a vast array of possibly confounding factors.

Vegetarian and omnivorous diets: A cross-sectional study of motivation, eating disorders, and body shape perception

Vegetarianism, which is increasingly widespread in Western societies, is underpinned by various motivations (ethical, environmental, health concerns …) and the question of its association with eating disorders continues to divide the literature. This cross-sectional study aimed to explore and compare eating motives/attitudes and bodily preoccupations of vegetarian and omnivorous participants from the general population. Forty-nine vegetarians and 52 omnivores, aged between 18 and 70 years, completed a battery of questionnaires including sociodemographic characteristics, Body Mass Indexes (BMI - current, ideal, lifetime lowest, and lifetime highest), the Food Choice Questionnaire (FCQ), the Eating Attitudes Test-26 (EAT-26), and the Body Shape Questionnaire (BSQ). Compared to omnivores, vegetarians reported lower current (p = .017), ideal (p = .009), and lifetime lowest (p = .005) BMIs, more motivations related to health (p = .001) and natural content (p < .0001), but less weight control motivations (p = .015). While no differences were observed in EAT-26 scores, vegetarians had lower BSQ total scores (p = .043), and lower scores on the Body Dissatisfaction related to Lower body parts (p = .025) and Unsuited Cognitions and Behaviors (p = .015) subscales compared to omnivores. Separate gender comparisons revealed that these differences existed only among women. Hierarchical regressions revealed that the natural content motivation was the strongest positive statistical predictor of the vegetarian group (Expβ = 1.18, p = .002), while the weight control motivation was a negative statistical predictor (Expβ = .710, p = .023). Results demonstrated that vegetarians expressed motivation for a healthy and natural diet, and were less concerned about controlling their weight than the omnivores. Vegetarian women had lower BMIs but expressed fewer psychological concerns associated with eating disorders than omnivorous women. Vegetarian diets appeared to be associated with health benefits and less body and weight concerns, particularly among women in the general population.

Body image and disordered eating in older women: A Tripartite Sociocultural model

Evidence suggests that body image concerns and disordered eating exist in women even at older ages. Few studies have examined the factors that are related with body image and eating concerns in this age group. In particular, the roles of sociocultural influences and thin-ideal internalization remain unclear. In the present study, we tested a modified tripartite sociocultural model of body image and disordered eating behaviors in a sample of 222 women aged 60 to 75 years, using structural equation modeling. After adjustment, a model similar to that observed in young women was a good fit to the data. Perceived pressure from the media revealed a direct relationship with body image concerns, as well as an indirect relationship mediated by thin-ideal internalization. Peer pressure was directly associated with body image concerns, and thin-ideal internalization was associated with dieting. In older women, pressure to conform to appearance ideals, in particular from the media, may impact the internalization of appearance ideals and body image concerns that might, in turn, increase disordered eating. The usefulness of sociocultural models for framing body image and eating concerns in older women implies that similar prevention interventions to those used in younger women could be adapted to fill a gap in available resources for this group.

Coping Strategies and Factors Related to Problematic Substance Use and Behavioral Addictions Among Adolescents and Young Adults with Cancer

Purpose: This study aimed to explore and identify the factors associated with problematic substance use (alcohol, tobacco, and cannabis) and behavioral addictions (internet and eating disorders) over time in adolescents and young adults (AYAs) treated for cancer. Methods: AYAs newly diagnosed with cancer, 15-25 years of age, completed a questionnaire during their hospitalization (T1), assessing their consumption of alcohol, tobacco, and cannabis (The Alcohol Use Disorders Identification Test; The Smoking Behavior Questionnaire; and The Cannabis Abuse Screening Test), their internet use (The Internet Addiction Test), their body preoccupations (The Eating Attitudes Test), as well as their coping strategies (Brief COPE) and emotional adjustment (The Hospital Anxiety and Depression Scale). Questionnaires were completed again 6 months later (T2). Results: Seventy-three AYAs were included at T1 and 21 AYAs at T2. Nearly one out of two (46.58%) AYAs had a problematic substance use or behavioral addiction after cancer diagnosis (T1). Problematic use of internet was frequently reported (23.29%), as well as harmful alcohol consumption or addiction (16.44%) and cannabis dependence (12.33%). The main factor related to problematic substance use was being older, while the main factor related to behavioral addiction was having a higher anxiety score. Substance use as a coping strategy was used more frequently by AYAs with problematic substance use and emotional support as a coping strategy was used more frequently by AYAs with a behavioral addiction. Conclusions: High rates of problematic substance use and behavioral addiction were reported in our sample. AYAs surveyed had high problematic use of cannabis and high internet use. Attention to substance use and addictive behaviors is recommended to ensure optimal care.

Psychometric Properties of the Body Checking Questionnaire (BCQ) and of the Body Checking Cognitions Scale (BCCS): A Bifactor-Exploratory Structural Equation Modeling Approach

This research sought to assess the psychometric properties of the French versions of the Body Checking Questionnaire and the Body Checking Cognitions Scale among community samples. A total sample of 922 adolescents and adults was involved in a series of two studies. The results from the first study supported factor validity and reliability of responses obtained on these two measures, and showed that both measures were best represented by a bifactor-exploratory structural equation modeling representation of the data. The results from the second study replicated these conclusions, while also supporting the measurement invariance of the bifactor-exploratory structural equation modeling solution and the equivalence of the correlations among the two measures (i.e., convergent validity) across samples. This second study also supported the criterion-related validity of ratings on both measures with measures of global self-esteem, physical appearance, social physique anxiety, fear of negative appearance evaluation, and disturbed eating attitudes and behaviors. Finally, the results of this last study also supported the measurement invariance and lack of differential item functioning of both measures in relation to sex, age, diagnosis of eating disorders, and body mass index.

Psychological Meanings of Eating Disorders and Their Association With Symptoms, Motivation Toward Treatment, and Clinical Evolution Among Outpatients

Unlike patients suffering from egodystonic disorders, people with eating disorders sometimes attribute positive meanings to their symptoms, and this attribution process contributes to the maintenance of the disorder. This study aims at exploring psychological meanings of eating disorders and their associations with symptoms, motivation toward treatment, and clinical evolution. Eighty-one adults with an eating disorder (anorexia nervosa, n = 46 and bulimia nervosa, n = 35) treated in a day-hospital program were asked, each week over an 8-week period, to identify the psychological meanings they ascribed to their eating disorder. Avoidance was the most frequently identified meaning, followed by mental strength, security, death, confidence, identity, care, and communication. Avoidance was more frequently mentioned by participants with bulimia than in cases of anorexia. Security and mental strength were associated with less motivation toward treatment. Death was associated with more depressive and anxious symptoms. An exploratory factor analysis showed that these meanings formed three main dimensions: Avoidance, Intrapsychic, and Relational. Findings suggest that psychological meanings associated with eating disorders can be assessed and used as a clinical tool to increase treatment acceptability and effectiveness.

Psychometric properties of the Weight Self-Stigma Questionnaire (WSSQ) among a sample of overweight/obese French-speaking adolescents

PURPOSE

The Weight Self-Stigma Questionnaire (WSSQ) was recently developed to assess the internalization of weight stigma among English-speaking overweight and obese adults. The objective of the present study was to develop and examine the psychometric properties of a French version of the WSSQ, as well as its applicability to adolescents.

METHODS

The sample comprised 156 overweight and obese adolescents (81 boys, 75 girls, M_age = 16.31). The factor validity and the convergent validity of the French version of the WSSQ were examined using a confirmatory factor analysis and a structural equation model, respectively.

RESULTS

The a priori two-factor structure of the WSSQ and the composite reliability of its subscales (self-devaluation and fear of enacted stigma) were supported. Convergent validity analyses revealed that both WSSQ subscales were significantly and (a) negatively correlated with measures of self-esteem and physical appearance, and (b) positively correlated with measures of anxiety, depression, fear of negative appearance evaluation, and eating-related pathology (fear of getting fat, eating-related control, food preoccupation, vomiting-purging behaviors, and eating-related guilt subscales). However, no significant relation was found between the WSSQ subscales and body mass index.

CONCLUSION

These results suggest that the French version of the WSSQ has acceptable psychometric properties and can be used to assess weight self-stigma among overweight and obese adolescents.

Effects of induced rumination on body dissatisfaction: Is there any difference between men and women?

BACKGROUND AND OBJECTIVES

Rumination is a factor in the development and maintenance of body dissatisfaction. However, no study has yet investigated the impact of the type of rumination on body image. The first aim of this study was to examine whether the induction of analytic-abstract vs. concrete-experiential rumination affects body dissatisfaction following an induction of negative body image. The second objective was to examine gender differences in these effects.

METHODS

Following induction of negative body image, 102 university undergraduates were randomly assigned to one of three experimental conditions-distraction, concrete rumination or abstract rumination.

RESULTS

As expected, there were significant main effects of gender and condition, and a significant interaction between gender and condition on change in body dissatisfaction. In women abstract rumination predicted the highest increase in body dissatisfaction, whereas concrete rumination predicted the highest increase in body dissatisfaction in men.

LIMITATIONS

Given that our sample consisted of undergraduate students, our findings cannot be generalized to clinical sample suffering from eating disorder.

CONCLUSIONS

The different types of rumination seem to impact differentially body dissatisfaction in men and women.

Assessing the factor structure and measurement invariance of the eating attitude test (EAT-26) across language and BMI in young Arab women

BACKGROUND

The objective of the study was to determine the factorial structure and test the measurement invariance of the EAT-26 in a large probability sample of young female university students in Qatar (n = 2692), a Muslim country in the Middle East.

METHODS

The maximum number of factors was derived based on results from initial exploratory factor analysis (EFA) in the first-half of the randomly split sample (Sample 1). A subsequent EFA and Exploratory Structural Equation Models (ESEM) were conducted to identify the number of valid factors. A five-factor model with 19 items was identified as the optimal factor structure. This structure was further replicated using ESEM in the second-half of the sample (Sample 2). Multi-group Confirmatory Factor Analyses (CFAs) were conducted at this stage and their fit was evaluated with and without further sub-grouping by language (Arabic and English) and BMI (underweight, normal weight, and overweight/obese). Finally, measurement invariance tests were conducted in the entire sample assessing equivalence across language and BMI within the final five-factor model.

RESULTS

The five-factor structure of the new EAT-19 [fear of getting fat (FGF), eating-related control (ERC), food preoccupation (FP), vomiting-purging behavior (VPB), and social pressure to gain weight (SP)] provided the best fit: CFI = 0.976, TLI = 0.952, RMSEA = 0.045 (90%CI 0.039-0.051), SRMR = 0.018, CD =1.000. CFAs supported metric invariance for language and for BMI. Language and BMI-based population heterogeneity comparisons provided modest and small-to-moderate evidence for differential factor means, respectively.

CONCLUSION

Although the five-factor model of the EAT-19 demonstrated good item characteristics and reliability in this young female population, the lack of scalar invariance across language and BMI-categories pose measurement challenges for use of this scale for screening purposes. Future studies should develop culture- and BMI-specific cut-offs when using the EAT as a screening instrument for disordered eating in non-clinical populations.

Personality profiles in young adults with disordered eating behavior

Personality traits are closely related to eating disorders (ED) and might be involved in their development and maintenance. Nevertheless little is known regarding the association between personality traits and disordered eating in subclinical populations. College students answered questionnaires assessing disordered eating behaviors (DEB) and the following personality disorder (PD) traits: schizotypal, autistic, obsessional, borderline and cyclothymic. Participants with DEB (n=101, 87% women) displayed significantly higher scores for several variables including schizotypy, cyclothymic, borderline and obsessional traits compared to other participants (n=378). Cluster analysis in the DEB subsample led to the identification of three groups: 1) a cluster with a high level of traits (HT); 2) a cluster scoring high on schizotypal, borderline and cyclothymic traits (SBC); 3) a cluster with a low level of traits (LT). Symptoms of depression, suicidal ideations, trait anger and obsessive-compulsive symptoms were higher in the HT and the SBC clusters compared to the LT cluster. Given that two thirds of participants suffering from DEB appeared to display a morbid personality profile, it appears of prime importance to take into account PD traits of individuals with DEB.

[External and internal validity of a multidimensional Locus of control scale of eating attitudes for athletes (LOCSCAS)]

In the field of health psychology, the control has consistently been considered as a protective factor. This protective role has been also highlighted in eating attitudes' domain. However, current studies use the one-dimensional scale of Rotter or the multidimensional health locus of control scale, and no specific eating attitudes' scale in the sport context exists. Moreover, the social influence in previous scales is limited. According to recent works, the purpose of this study was to test the internal and external validity of a multidimensional locus of control scale of eating attitudes for athletes. One hundred and seventy-nine participants were solicited. A confirmatory factorial analysis was conducted in order to test the internal validity of the scale. The scale external validity was tested in relation to eating attitudes. The internal validity of the scale was verified as well as the external validity, which confirmed the importance of taking into consideration social influences. Indeed, the 2 subscales "Trainers, friends" and "Parents, family" are related respectively positively and negatively in eating disorders.

Development and validity of a very short form of the Eating Disorder Inventory

INTRODUCTION

The main objective of the present series of studies was to develop and validate a 16-item very short form of the Eating Disorder Inventory (EDI-VS) for use as a short assessment tool in large-scale comprehensive or longitudinal studies, as well as in-depth idiographic studies.

METHOD

The EDI-VS was developed, and validated, through a series of five studies based on independent community samples including a total of 1372 French adolescents.

RESULTS

The results supported the reliability, content validity, factor validity, convergent validity, and criterion-related validity of the EDI-VS.

CONCLUSIONS

The EDI-VS comprises 16 items assessing the eight original dimensions of the conceptual model for the EDI. Recommendations for future practice and research on the EDI-VS are outlined.

A prospective study of effects of prenatal maternal stress on later eating-disorder manifestations in affected offspring: preliminary indications based on the Project Ice Storm cohort

BACKGROUND

Research associates maternal stress exposures (especially when occurring late in gestation) with heightened risk of subsequent emotional and behavioral problems in affected offspring. However, as yet, no study has examined the association between prenatal maternal stress (PNMS) and affected children's risk of anorexia- or bulimia-type eating disturbances.

OBJECTIVE

To study the influences of PNMS on later disordered eating in exposed offspring.

METHOD

We used the Eating Attitudes Test (EAT)-26 to measure eating attitudes and behaviors in 54 thirteen-year olds whose mothers had been exposed, while pregnant with these children, to the 1998 Quebec Ice Storm-a natural disaster regarded as a model of exposure to severe environmental stress. Mothers' stress was measured shortly after exposure to the storm using established indices of objective and subjective stress.

RESULTS

Hierarchical multiple linear regression analyses indicated that once variance owing to children's body mass index and sex was accounted for, stress exposures during the third trimester of pregnancy predicted elevated EAT-26 scores in affected children-perhaps even more so when levels of objective stress were high.

DISCUSSION

Third trimester exposure to PNMS, especially when objectively severe, seems to be associated with increased eating-disorder-linked manifestations in affected early adolescents.

Symptoms of depression and anxiety in anorexia nervosa: links with plasma tryptophan and serotonin metabolism

Depressive, anxiety and obsessive symptoms frequently co-occur with anorexia nervosa (AN). The relationship between these clinical manifestations and the biological changes caused by starvation is not well understood. It has been hypothesised that reduced availability of tryptophan (TRP) could reduce serotonin activity and thus trigger these comorbid symptoms. The aim of this study, during re-feeding in individuals with AN, was to analyse covariations across measures of nutritional status, depressive and anxiety symptoms, and peripheral serotonin markers. Depressive and anxiety symptoms, nutritional status and serotonin markers--whole blood serotonin content, plasma TRP and the ratio between TRP and large neutral amino acids--were assessed for 42 AN participants at admission to inpatient treatment and after re-feeding. Biological measures were compared to those obtained in 42 non-eating disordered subjects. For those with AN, psychological, nutritional and biological parameters improved significantly during hospitalisation. Levels of serotonin markers were significantly lower in the AN group compared to the control group, at admission and at discharge. Increase in the TRP/LNAA ratio was correlated with a decrease in depressive symptoms. In addition, there was a positive correlation between serotonin levels and symptoms of both anxiety and depression at discharge. We speculate that enhanced TRP availability during re-feeding, as a result of the increase in the TRP/LNAA ratio, could restore serotonin neurotransmission and lead to a decrease in depressive symptoms. The association between serotonin and anxiety and depressive symptoms would be consistent with numerous observations indicating abnormal functioning of the serotoninergic system in AN.

The Eating Attitudes Test-26 revisited using exploratory structural equation modeling

Most previous studies have failed to replicate the original factor structure of the 26-item version of the Eating Attitudes Test (EAT-26) among community samples of adolescents. The main objective of the present series of four studies (n = 2178) was to revisit the factor structure of this instrument among mixed gender community samples of adolescents using both exploratory structural equation modeling (ESEM) and confirmatory factor analysis (CFA). First, results from the ESEM analyses provided satisfactory goodness-of-fit statistics and reliability coefficients for a six-factor model of the EAT with 18 items (EAT-18) closely corresponding to the original seven-factor structure proposed for the 40-item version of the EAT. Second, these analyses were satisfactorily replicated among a new sample of community adolescents using CFA. The results confirmed the factor loading and intercept invariance of this model across gender and age groups (i.e., early and late adolescence), as well as the complete invariance of the EAT-18 measurement model between ethnicities (i.e., European versus African origins) and across weight categories (i.e., underweight, normal weight and overweight). Finally, the last study provided support for convergent validity of the EAT-18 with the Eating Disorder Inventory and with instruments measuring global self-esteem, physical appearance, social physique anxiety and fear of negative appearance evaluation.

Internet addiction symptoms, disordered eating, and body image avoidance

Internet addiction is an increasing concern among young adults. Self-presentational theory posits that the Internet offers a context in which individuals are able to control their image. Little is known about body image and eating concerns among pathological Internet users. The aim of this study was to explore the association between Internet addiction symptoms, body image esteem, body image avoidance, and disordered eating. A sample of 392 French young adults (68 percent women) completed an online questionnaire assessing time spent online, Internet addiction symptoms, disordered eating, and body image avoidance. Fourteen men (11 percent) and 26 women (9.7 percent) reported Internet addiction. Body image avoidance was associated with Internet addiction symptoms among both genders. Controlling for body-mass index, Internet addiction symptoms, and body image avoidance were both significant predictors of disordered eating among women. These findings support the self-presentational theory of Internet addiction and suggest that body image avoidance is an important factor.
