Screening disordered eating in a representative sample of the German population: Usefulness and psychometric properties of the German SCOFF questionnaire

Understanding the impact of COVID-19 on comorbid depression, anxiety and eating disorders in adolescent psychiatric inpatients: a network analysis

BACKGROUND

Many studies have aimed to understand the impact of the COVID-19 pandemic on mental health. However, less research has focused on the changes in symptom clusters of comorbid disorders. To understand the impact of the COVID-19 pandemic it is necessary to evaluate the relationships between symptoms of comorbid disorders. This was the first study to compare comorbidity networks of depression, anxiety and eating disorder (ED) symptoms to investigate the overall connectivity of symptoms before and during the onset of the pandemic.

METHODS

Self-report questionnaire data from 1361 adolescent psychiatric inpatients (Mage = 15.32, SD = 1.47) were used for this study. A network analysis was conducted including 52 questionnaire items of depression, anxiety and eating disorder to identify and compare core symptoms and bridge symptoms in a pre and a peri pandemic sample.

RESULTS

A significantly higher network density and overall connectivity were found in the peri pandemic sample. Links between feelings of failure in the depression cluster and worry what other people think in the anxiety cluster as well as between difficulties getting rid of bad/ silly thoughts in the anxiety cluster and suicidal thoughts in the depression cluster emerged as the strongest pathways in both networks. Body image disturbance emerged as the strongest bridge symptom for eating disorders in both networks. There were no significant differences in the most prominent core and bridge symptoms between the networks, indicating a high stability of core symptoms and pathways across circumstances.

CONCLUSIONS

Our findings suggest a multidimensional relationship between symptoms of depression, anxiety, and eating disorders. The persistence of symptom pathways after the onset of the pandemic implies that these pathways may be responsible for the occurrence of comorbidity and should be primary targets of psychotherapy for affected patients. Addressing core and bridge symptoms in the therapy of comorbid disorders should be a priority and may be more effective than conventional treatment strategies.

Psychometric properties of a German translation of the Functionality Appreciation Scale (FAS) among adults in Germany

The Functionality Appreciation Scale (FAS; Alleva et al., 2017) is a widely used instrument to measure appreciation for what the body is able to do. However, it has yet to be translated and validated for use in German-speaking populations. The aim of the present work therefore was to validate a German translation of the FAS following the EFA-to-CFA approach. Results of this validation in a representative sample with N = 2570 participants (1300 women, 1270 men) and a community sample with N = 466 participants (371 women, 95 men) indicate good psychometric properties and support the factorial validity, measurement invariance across women and men, construct validity (through associations with body appreciation, body dissatisfaction, self-esteem, mindfulness, intuitive eating, restrained eating, drive for thinness, and risk for disordered eating), incremental validity, internal consistency and preliminarily support the 2-4 week test-retest reliability of the German FAS. A qualitative analysis of participant feedback on understanding and subjective response difficulty provided additional support for the validity of the German translation of the FAS. Overall, the FAS is a suitable instrument for measuring functionality appreciation in adults from Germany.

Smartphone screen time reduction improves mental health: a randomized controlled trial

BACKGROUND

Smartphone screen time has risen sharply in recent years. Even though an association between smartphone use and mental health is well documented, it is still unclear whether this is simply a correlation or causality. The aim of this study is to investigate the effects of smartphone screen time reduction on mental health indicators.

METHODS

This non-blinded, parallel randomized controlled trial (RCT) was performed to investigate the impact of a 3-week screen time reduction to ≤ 2 h/d in healthy students on stress (PSQ), well-being (WHO-5), depressive symptoms (PHQ-9), and sleep quality (ISI) at baseline (t0), post-intervention (t1), and at follow-up (t2 = 6 weeks after t1). For the intention to treat analysis, repeated measures ANOVAs and post-hoc tests (for time as well as group differences) were performed and effect sizes were presented as partial eta squared (η2 = time × group) and group-mean differences.

RESULTS

In total, 111 out of 125 healthy students (70 females; mean age = 22.68 ± 2.6 years; mean screen time = 276 ± 115.1 min/day) were randomly assigned to intervention-(n = 58; 3 weeks of screen time reduction to ≤ 2 h/day) or control group (n = 53). Although no differences were observed at baseline (t0), significant post-intervention (t1) effects of small to medium size were observed on well-being (η2 = .053), depressive symptoms (η2 = .109), sleep quality (η2 = .048), and stress (η2 = .085). Significant group differences (p ≤ .05) were found post-intervention (t1) for depressive symptoms (Mean Difference (MD) = 2.11, Standard Error (SE) = 0.63, 95% Confidence Interval (CI) [0.87, 3.36]), sleep quality (MD = 2.59, SE = 0.97, 95% CI [0.66, 4.51]), well-being (MD = -1.54, SE = 0.68, 95% CI [.-2.89, -0.18]), and stress (MD = 6.91, SE = 3.48, 95% CI [0.01, 13.81]). Screen time increased rapidly after the intervention and at follow-up the values were once again approaching the initial level.

CONCLUSIONS

The study highlights mental health improvements through smartphone screen time reduction. Three weeks of screen time reduction showed small to medium effect sizes on depressive symptoms, stress, sleep quality, and well-being. The results suggest a causal relationship, rather than a merely correlative one, between daily smartphone screen time and mental health.

TRIAL REGISTRATION

The study was preregistered on Open Science Framework (trial registration number: A9K76) on November 8, 2023.

Measuring disordered eating in adolescent boys: a systematic literature review

PURPOSE

The aim of this study was to map which instruments are currently being used to measure disordered eating in adolescent boys as part of a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis.

METHOD

Utilizing the PRISMA review protocol, 174 journal articles were reviewed.

RESULTS

Sixty-seven articles used versions of the Eating Attitudes Test to measure adolescent boys' disordered eating, 32 used versions of the Eating Disorder Examination-Questionnaire, 30 used versions of the Eating Disorder Inventory, 25 used SCOFF, and 10 used the Drive for Muscularity Scale. A plethora of other instruments for measuring disordered eating were utilized as well.

CONCLUSION

Studying adolescent boys' disordered eating by using instruments primarily developed and validated for girls may provide unreliable estimates of the numbers of boys who suffer from disordered eating, which would preclude early intervention. One strength of the reviewed studies was that several used multiple measurements to validate their results. One of the weaknesses was the lack of distinguishing genders among certain groups, such as athletes or patients. Among the opportunities identified was the possibility of expanding on research on the association between puberty and disordered eating, with sports and parents potentially acting as buffers against the onset of disordered eating. A clear threat to research on disordered eating among adolescent boys was the (in)accuracy of the measurements.

Validation of the SCOFF as a Simple Screening Tool for Eating Disorders in an Inpatient Sample Before and During COVID-19

OBJECTIVE

Eating disorders (EDs) represent a significant public health concern, with a high prevalence among adolescent girls. The COVID-19 pandemic has led to a marked increase in EDs, underlining the need for a brief screening tool in clinical settings. The present study compared ICD-10-based ED-diagnoses with SCOFF-identified at-risk female patients in a clinical setting and assessed the tool's reliability.

METHOD

Routine data (n = 955 participants) from a child and adolescent psychiatric hospital were evaluated regarding the incidence of ED-diagnoses before (n = 312) and during the pandemic (n = 643) and compared with SCOFF results. The SCOFF's sensitivity and specificity were examined.

RESULTS

ED-diagnoses significantly increased, almost doubling from before to during the pandemic. The number of at-risk patients identified by the SCOFF likewise differed between the two time points. The SCOFF showed high sensitivity at cut-offs of 2 (pre-pandemic) and 3 (peri-pandemic) but low specificity. Internal consistency was poor.

DISCUSSION

The findings align with previous research indicating an elevated rate of admission to clinical care for ED-diagnoses during the pandemic, a trend also reflected in the SCOFF results. However, the SCOFF's low specificity and poor internal consistency raise concerns about its applicability among adolescent psychiatric inpatients.

Eating disorders and health literacy in Germany: results from two representative samples of adolescents and adults

Introduction

Eating disorders are associated with substantial burden for the affected individuals including negative health outcomes and increased mortality. So far, prevention programs for eating disorders have yielded mixed results concerning their efficacy. Therefore, more targeted prevention programs need to be developed. Health literacy has been identified as a potential influencing factor of eating disorders. This study aimed at exploring the relationship between likely cases of eating disorders and health literacy, alongside additional sociodemographic factors.

Materials and methods

Two large samples of adults (N = 3,011) and adolescents (N = 1,021) representative of the German-speaking population in Germany were recruited. Likely cases of eating disorders were identified using the SCOFF questionnaire. Health literacy was assessed with the HLS-EU-Q16 questionnaire. Sociodemographic information, including age, gender, social status and level of education, and subjective body image were obtained. χ2-tests of independence were calculated to determine the association between the investigated constructs.

Results

Suspected eating disorders were more likely in female than male adolescents but were not related to gender in adults. Rates of suspected eating disorders increased with increasing age in adolescents and decreased with increasing age in adults. While levels of education were unrelated to suspected eating disorders, low social status was associated with higher rates of suspected eating disorders in adults but not adolescents. Inadequate or problematic health literacy and negative body image were associated with higher rates of suspected eating disorders compared to adequate health literacy and more positive body image.

Discussion

Likely cases of eating disorders are related to health literacy and body image as well as sociodemographic factors. These constructs should therefore be addressed in future research to improve prevention programs.

The Sick, Control, One Stone, Fat, Food (SCOFF) is a Valid Eating Disorder Questionnaire to Use With Transgender Youth

Transgender youth experience elevated rates of eating disorders, yet few screening measures have been validated with transgender patients. The purpose of this study was to provide initial evidence for the internal consistency and convergent validity of the Sick, Control, One Stone, Fat, Food (SCOFF) in a sample of transgender youth. Two hundred eight participants completed the SCOFF as part of a routine screening protocol. Exploratory factor analysis and confirmatory factor analysis were used to establish the factor structure of the SCOFF in this sample. Relationships between the SCOFF, Adolescent Binge Eating Disorder (ADO-BED), Nine-Item Avoidant/Restrictive Intake Disorder (NIAS), Patient Health Questionnaire 9 (PHQ-9), Generalized Anxiety Disorder 7 (GAD-7), and demographic characteristics were explored. The SCOFF was significantly related to all convergent validity variables, with moderate correlations with other eating disorder scales (ADO-BED and NIAS). The SCOFF is a valid measure to screen for eating disorders among transgender youth and young adults.

The Relationship between Patient Self-Reported, Pre-Morbid Physical Activity and Clinical Outcomes of Inpatient Treatment in Youth with Anorexia Nervosa: A Pilot Study

Links between premorbid physical activity (PA) and disease onset/course in patients with anorexia nervosa (AN) remain unclear. The aim was to assess self-reported PA as a predictor of change in percent median BMI (%mBMI) and length of hospital stay (LOS). Five PA domains were assessed via semi-structured interview in adolescents with AN at hospitalization: premorbid PA in school grades 1-6 (PA1-6); PA before AN onset (PA-pre) and after AN onset (PA-post); new, pathological motivation for PA (PA-new); and high intensity PA (PA-high). Eating disorder psychopathology was measured via the Eating Disorder Examination Questionnaire (EDE-Q), and current PA (steps/day) with accelerometry. PA1-6 was also assessed in healthy controls (HCs). Using stepwise backward regression models, predictors of %mBMI change and LOS were examined. Compared with 22 HCs (age = 14.7 ± 1.3 years, %mBMI = 102.4 ± 12.1), 25 patients with AN (age = 15.1 ± 1.7 years, %mBMI = 74.8 ± 6.0) reported significantly higher PA1-6 (median, AN = 115 [interquartile range IQR = 75;200] min vs. HC = 68 [IQR = 29;105] min; p = 0.017). PA-post was 244 ± 323% higher than PA-pre. PA1-6 was directly associated with PA-pre (p = 0.001) but not with PA-post (p = 0.179) or change in PA-pre to PA-post (p = 0.735). Lower %mBMI gain was predicted by lower baseline %mBMI (p = 0.001) and more PA-high (p = 0.004; r2 = 0.604). Longer LOS was predicted by higher PA-pre (p = 0.003, r2 = 0.368). Self-reported PA may identify a subgroup of youth with AN at risk of less weight gain and prolonged LOS during inpatient treatment for AN.

Comprehensive examination of support needs and mental well-being: a mixed-method study of the Austrian general population in times of crisis

Introduction

In the recent years, the Austrian general population has faced a confluence of multiple crises. This study investigates the support wishes and mental health parameters of the Austrian general population aiming to comprehending the unmet needs and providing guidance for future psychosocial interventions and research endeavors.

Methods

1,031 participants attended the online survey and one third (n = 332) wished for further support to improve mental well-being in April 2022. A total of 280 participants accompanied their support wish with written accounts. Participants' mental health status was evaluated using the PHQ-9 (depression), GAD-7 (anxiety), ISI (insomnia), PSS-10 (perceived stress), CAGE (alcohol abuse), WHO-5 (well-being), and the SCOFF (eating disorder) questionnaires. Data analysis employed a mixed-methods approach.

Results

The preeminent support wish identified was the need for professional mental support (29.3%), followed by communication (21.6%), other professional support except mental and medical support (13.9%). In line with these findings, participants expressing a support wish experienced increased mental health distress across all assessed parameters.

Conclusion

The findings indicate the presence of a vulnerable population within the Austrian general population, which may benefit from targeted support interventions. Consequently, this study contributes to the identification of unmet support needs among the Austrian populace during times of crisis, facilitating the development and enhancement of precisely tailored intervention strategies.

The use and misuse of the SCOFF screening measure over two decades: a systematic literature review

PURPOSE

The SCOFF questionnaire was designed as a simple, memorable screening tool to raise suspicion that a person might have an eating disorder. It is over 20 years since the creation of the SCOFF, during which time it has been widely used. Considering this, we wish to review the use of the SCOFF in peer-reviewed scientific journals, and to assess whether it is being used appropriately in the manner in which it was originally devised and tested.

METHODS

The Preferred Reporting Items for a Systematic Review and Meta-analysis (PRISMA) guidelines were followed, and all search strategies and methods were determined before the onset of the study. PubMed and Wiley Online Library were searched using the terms SCOFF and eating. Two reviewers were involved in the reviewing process. Criteria for appropriate use of the SCOFF were formalised with the tool's original authors.

RESULTS

180 articles were included in the final review. 48 articles had used the SCOFF appropriately, 117 articles inappropriately and 15 articles had been mixed in the appropriateness of their use.

CONCLUSION

This systematic review highlights the inappropriate use of the SCOFF in diverse languages and settings. When used correctly the SCOFF has made a significant contribution to the understanding of eating disorders and its simplicity has been applauded and led to widespread use. However in over two-thirds of studies, the use of the SCOFF was inappropriate and the paper highlights how and in what way it was misused, Guidelines for the appropriate use of the SCOFF are stated. Future validation and avenues of research are suggested.

"Good food equals good health": a focus group study of adolescent boys' perceptions of eating and weight

BACKGROUND

Disordered eating refers to unhealthy, sometimes excessive eating including so-called compensatory behaviours such as extreme dieting or voluntary vomiting. Between 24% and 30% of adolescent boys are suggested to engage in disordered eating, making it a significant public health issue. However, current instruments for assessing disordered eating among adolescents have been primarily developed and validated for girls and women, which may make for flawed assessment of boys. The aim of this study is to shed light on adolescent boys' perceptions of eating, weight, and food intake to better understand their perspectives in service of disordered eating research.

METHODS

This exploratory study was conducted from May to November 2022 using focus groups with a total of 39 adolescent boys (aged 12-19 years) who attended 7th to 12th grade in one of four schools in Southern Sweden. In addition, participants completed a form with questions on background demographics and eating habits. The transcripts of the focus group discussions were analysed using thematic analysis.

RESULTS

The quantitative data showed that around one third of the adolescent boys were overweight or obese. They ate at least one meal per day with the family and ate healthy food about five days per week and unhealthy food about three. Analysis of the qualitative data yielded six themes: The intertwined relationship between food and one's health, "Don't worry, food makes you happy," "To be hungry or not. That is the question," Boys DO care about appearances, Dieting and weight gain, and Disordered eating is a tricky matter.

CONCLUSION

Adolescent boys appeared to have a good understanding of food and healthy eating. They also experienced body positivity and seemed to have only minor issues regarding their weight. The primarily pathological perspective used to measure disordered eating among girls seems in need of revision to adhere to boys' thoughts and ideas regarding eating and weight.

An Assessment of Austrian School Students' Mental Health and Their Wish for Support: A Mixed Methods Approach

The mental health of school students has been severely impacted by the aftermath of the COVID-19 pandemic. The present study used a mixed methods approach to assess students' mental health and examine their wishes for support to improve their psychological well-being. We further investigated gender and age group differences in the amount of clinically relevant mental health problems and the roles that mental health and gender had on desired support. Between April and May 2022, a total of 616 Austrian students aged between 14 and 20 participated in a cross-sectional online survey (77.4% female; 19.8% male; 2.8% non-binary) assessing wishes for support regarding mental well-being and mental health indicators (depression: PHQ-9; anxiety: GAD-7; insomnia: ISI; stress: PSS-10; eating disorders: SCOFF; alcohol abuse: CAGE). A wish for support was expressed by 46.6% of the students. Qualitative content analysis revealed that the two most important categories of desired support types were "professional help" and "someone to talk to". The group of students with a wish for support in general significantly more often showed clinically relevant depression, anxiety, insomnia, eating disorders, or high stress symptoms. Students that wished for professional help significantly more often exceeded the cut-off for clinically relevant depression, anxiety, and high stress. Those who wished for someone to talk to significantly more often exceeded the cut-off for clinically relevant eating disorders. The results indicate a great need for support for young people's mental health problems and that this need is even more urgent for students.

Prevalence of probable eating disorders and associated risk factors: An analysis of the Northern Ireland Youth Wellbeing Survey using the SCOFF

OBJECTIVES

Eating disorders (ED) are associated with significant morbidity and mortality rates and are most common in young people aged between 15 and 19 years. Large representative surveys on disordered eating in youth are lacking. The main aims were to estimate the prevalence of disordered eating in a representative sample of 11-19 year olds in Northern Ireland and investigate the associations between probable eating disorder and a range of risk factors.

DESIGNS AND METHODS

A large nationally representative household survey was conducted, and the bivariate and multivariate associations between demographic, familial, economic and psychological risk factors and probable eating disorder were assessed.

RESULTS

A total of 16.2% (n = 211) of the sample met the SCOFF screening criteria for disordered eating. Probable eating disorder was associated with being female (OR = 2.44), having a parent with mental health problems (OR = 1.68), suffering from certain psychological problems, such as mood or anxiety disorder (OR = 2.55), social media disorder (OR = 2.95), being the victim of physical bullying (OR = 1.71) and having smoked (OR = 2.46).

CONCLUSIONS

This study provides the first prevalence estimates of probable eating disorder among youth in Northern Ireland. Furthermore, the study identifies unique risk factors for probable eating disorder among this representative sample.

An experimental approach to training interoceptive sensitivity: study protocol for a pilot randomized controlled trial

BACKGROUND

Eating in absence of hunger is quite common and often associated with an increased energy intake co-existent with a poorer food choice. Intuitive eating (IE), i.e., eating in accordance with internal hunger and satiety cues, may protect from overeating. IE, however, requires accurate perception and processing of one's own bodily signals, also referred to as interoceptive sensitivity. Training interoceptive sensitivity might therefore be an effective method to promote IE and prevent overeating. As most studies on eating behavior are conducted in younger adults and close social relationships influence health-related behavior, this study focuses on middle-aged and older couples.

METHODS

The present pilot randomized intervention study aims at investigating the feasibility and effectiveness of a 21-day mindfulness-based training program designed to increase interoceptive sensitivity. A total of N = 60 couples participating in the NutriAct Family Study, aged 50-80 years, will be recruited. This randomized-controlled intervention study comprises three measurement points (pre-intervention, post-intervention, 4-week follow-up) and a 21-day training that consists of daily mindfulness-based guided audio exercises (e.g., body scan). A three-arm intervention study design is applied to compare two intervention groups (training together as a couple vs. training alone) with a control group (no training). Each measurement point includes the assessment of self-reported and objective indicators of interoceptive sensitivity (primary outcome), self-reported indicators of intuitive and maladaptive eating (secondary outcomes), and additional variables. A training evaluation applying focus group discussions will be conducted to assess participants' overall acceptance of the training and its feasibility.

DISCUSSION

By investigating the feasibility and effectiveness of a mindfulness-based training program to increase interoceptive sensitivity, the present study will contribute to a deeper understanding of how to promote healthy eating in older age.

Eating Concerns Associated with Nutritional Information Obtained from Social Media among Saudi Young Females: A Cross-Sectional Study

Eating disorders have been highly prevalent in young females for decades for many reasons. Social media platforms have an enormous impact on users, especially young adults, who use them every day. In Saudi Arabia, social media is popular, with an estimated 72% of users being active in 2020. Therefore, the primary aim of this study was to assess the relationship between using social media to search for nutritional information and eating concerns. A nationwide study was conducted on 1092 young Saudi females aged 18-30 years from five administrative regions in the Kingdom of Saudi Arabia. Data were collected using an online validated questionnaire, and symptoms of eating concerns were assessed using two brief instruments: SCOFF [Sick, Control, One Stone, Fat, Food] and Eating disorders Screen for Primary care [ESP]. The prevalence of eating concerns was 49.6% among Saudi females. Moderate eating concerns were more prevalent in the central region 24.8%, whereas high eating concerns were more prevalent in the southern region 27.6%. Personal accounts of dietitian/nutritionists (OR = 1.170; 95% CI 1.071-1.277; p ≤ 0.001), interaction with offered experiments about new meals/restaurants, and diets on social media that were mostly promoted by celebrities/influencers (OR = 1.554; 95% CI 1.402-1.723; p ≤ 0.000) were the most prominent risk factors associated with being more likely to suffer from eating concerns. The present study recommends opening clinics specializing in nutrition on social media platforms that target young females to provide nutritional counselling and encourage a healthy lifestyle. In addition, it is important to plan awareness campaigns intended to educate young females on how to deal with messages that circulate on social media without any evidence regarding their truthfulness.

Mastery Is Associated With Weight Status, Food Intake, Snacking, and Eating Disorder Symptoms in the NutriNet-Santé Cohort Study

Mastery is a psychological resource that is defined as the extent to which individuals perceive having control over important circumstances of their lives. Although mastery has been associated with various physical and psychological health outcomes, studies assessing its relationship with weight status and dietary behavior are lacking. The aim of this cross-sectional study was to assess the relationship between mastery and weight status, food intake, snacking, and eating disorder (ED) symptoms in the NutriNet-Santé cohort study. Mastery was measured with the Pearlin Mastery Scale (PMS) in 32,588 adults (77.45% female), the mean age was 50.04 (14.53) years. Height and weight were self-reported. Overall diet quality and food group consumption were evaluated with ≥3 self-reported 24-h dietary records (range: 3-27). Snacking was assessed with an ad-hoc question. ED symptoms were assessed with the Sick-Control-One-Fat-Food Questionnaire (SCOFF). Linear and logistic regression analyses were conducted to assess the relationship between mastery and weight status, food intake, snacking, and ED symptoms, controlling for sociodemographic and lifestyle characteristics. Females with a higher level of mastery were less likely to be underweight (OR: 0.88; 95%CI: 0.84, 0.93), overweight [OR: 0.94 (0.91, 0.97)], or obese [class I: OR: 0.86 (0.82, 0.90); class II: OR: 0.76 (0.71, 0.82); class III: OR: 0.77 (0.69, 0.86)]. Males with a higher level of mastery were less likely to be obese [class III: OR: 0.75 (0.57, 0.99)]. Mastery was associated with better diet quality overall, a higher consumption of fruit and vegetables, seafood, wholegrain foods, legumes, non-salted oleaginous fruits, and alcoholic beverages and with a lower consumption of meat and poultry, dairy products, sugary and fatty products, milk-based desserts, and sweetened beverages. Mastery was also associated with lower snacking frequency [OR: 0.89 (0.86, 0.91)] and less ED symptoms [OR: 0.73 (0.71, 0.75)]. As mastery was associated with favorable dietary behavior and weight status, targeting mastery might be a promising approach in promoting healthy behaviors.

The translation and psychometric assessment of the SCOFF eating disorder screening questionnaire: the Persian version

BACKGROUND

Eating Disorders (EDs) are defined by abnormal eating habits. The SCOFF (Sick-Control-One stone-Fat-Food) is a simple screening questionnaire for EDs. This study was conducted to translate and evaluate the psychometric properties of the SCOFF questionnaire in Iranian university students.

METHODS

A total of 310 Iranian students of the Shahid Beheshti University of Medical Sciences completed a test battery of questionnaires including the well-known screener of eating disorder symptoms, the SCOFF. All measures were presented to the participants in Persian. The 5-item SCOFF questionnaire was translated to Persian using the forward-backward method. The face, content, criterion, and construct validity of the Persian version of the SCOFF were assessed. The validity and reliability of the Persian version of the SCOFF was assessed and factor analysis was conducted.

RESULTS

All five items of the translated questionnaire were approved after face validity. Content validity ratio was 0.73 (range 0.66-0.83) and content validity index was 0.96 (range 0.91-1), so all items were approved. Exploratory factor analysis revealed a 2-factor structure, which explained 52.47% of the variance. Confirmatory factor analysis showed a very good goodness-of-fit for the 2-factor model. 2-factor and 1-factor models indicate a very good goodness-of-fit in females and adequate goodness-of-fit in males. Criterion validity showed an acceptable correlation between the SCOFF and the EDE-Q. Reliability was acceptable based on the stability [ICC = 0.905(95% CI .760-.962 p < 0.001)] and the internal consistency (KR20 = 0.4).

CONCLUSION

Appropriate psychometric properties of the 5-item Persian version of the SCOFF (both models) were confirmed, suggesting its use as a valid questionnaire in EDs screening.

The relationship between the risk of eating disorder and meal patterns in University students

PURPOSE

This study was carried out to evaluate the relation between meal patterns and the risk of eating disorders in university students.

METHODS

The study was conducted on a total of 331 volunteer students with a mean age of 22.08 ± 1.80 years, 56.5% female. Participants' sociodemographic characteristics, health information and eating habits like meal skipping and dieting were questioned. Sick, Control, One stone, Fat, Food (SCOFF) Eating Disorders Scale and Eating Disorder Examination Questionnaire (EDE-Q) were used to determine eating behavior disorders, with face to face interviews by the researches.

RESULTS

A significant correlation was found between dieting and skipping meals and the risk of eating disorders in both genders (p < 0.05). In addition, when the reasons for skipping meals were questioned, a significant relationship was detected between skipping meals and eating behaviour disorders by 3.285 times (p = 0.000). Also, every unit of increase in body mass index (BMI) values of individuals who participated to the study led to an increase in eating disorders by a factor of 1.262 (p = 0.000).

CONCLUSIONS

Our findings support concerns about the negative health effects of increasing overweight among university students in accordance with the data that the increase in BMI values led to an increase in eating disorders. Notably a significant correlation was found between dieting, skipping meals and the risk of eating disorders in both genders it is highlighting the need for monitoring and early diagnosis of eating disorders in youth with simple scales like SCOFF.

Resilience Is Associated with Less Eating Disorder Symptoms in the NutriNet-Santé Cohort Study

Resilience is a positive psychological trait associated with a lower risk of some physical and mental chronic diseases and could be an important protective factor against eating disorders (EDs). The aim of this study was to assess cross-sectional and longitudinal associations between resilience and ED in a large cohort of French adults. In 2017, a total of 25,000 adults from the NutriNet-Santé cohort completed the Brief Resilience Scale (BRS). ED symptoms were measured in 2017 and 2020, with the Sick-Control-One-Fat-Food (SCOFF) questionnaire. Cross-sectional and longitudinal associations between resilience and EDs were analyzed using logistic regression, controlling for sociodemographic and lifestyle characteristics. Cross-sectional analyses showed that more resilient participants exhibited EDs less frequently than did less resilient participants (p < 0.0001). Longitudinal analyses showed that, during the three years of follow up, higher resilience was negatively associated with incident EDs (OR: 0.67, 95%CI: 0.61–0.74), persistent EDs (0.46 (0.42–0.51)), and intermittent EDs (0.66 (0.62–0.71)), compared with no ED. More resilient participants were also less likely to have a persistent ED than to recover from EDs (0.73 (0.65–0.82)). This study showed that resilience was associated with less ED symptoms and a higher chance of recovery.

Overcoming limitations of self-report: an assessment of fear of weight gain in anorexia nervosa and healthy controls using implicit association tests

BACKGROUND

Fear of weight gain is a characteristic feature of anorexia nervosa (AN), and reducing this fear is often a main target of treatment. However, research shows that 20% of individuals with AN do not report fear of weight gain. Studies are needed that evaluate the centrality of fear of weight gain for AN with a method less susceptible to deception than self-report.

METHODS

We approximated implicit fear of weight gain by measuring implicit drive for thinness using implicit association tests (IATs). We asked 64 participants (35 AN, 29 healthy controls [HCs]) to categorize statements as pro-dieting vs. non-dieting and true vs. false in a questionnaire-based IAT, and pictures of underweight vs. normal-weight models and positive vs. negative words in a picture-based IAT using two response keys. We tested for associations between implicit drive for thinness and explicitly reported psychopathology within AN as well as group differences between AN and HC groups.

RESULTS

Correlation analyses within the AN group showed that higher implicit drive for thinness was associated with more pronounced eating disorder-specific psychopathology. Furthermore, the AN group showed a stronger implicit drive for thinness than HCs in both IATs.

CONCLUSION

The results highlight the relevance of considering fear of weight gain as a continuous construct. Our implicit assessment captures various degrees of fear of weight gain in AN, which might allow for more individually tailored interventions in the future.

Disordered eating among Arab and Jewish youth in Israel: the role of eating dinner with the family

Background

Disordered eating (DE), defined as unhealthy eating attitudes and behaviors, is considered a major public health problem among adolescents. Nevertheless, rates of DE among Arab and Jewish adolescents in Israel are still unknown. Furthermore, while previous studies have highlighted the role of frequent family meals as a protective factor against DE, studies examining home family dinners relative to other common dinner options (e.g., eating at home alone, eating out of the home, not eating dinner at all) are largely unavailable. We sought to use representative data of middle and high-school children in Israel in order to identify rates of DE among Arabs and Jews, while examining the relations of home family dinners (vs. other dinner options) with DE.

Methods

A nationally representative school-based survey of 4926 middle and high-school children (11–19 years old) was conducted during 2015–2016. Participants indicated where and with whom they had eaten dinner the day before. The 5-item SCOFF questionnaire was used (> 2 affirmative items were considered a likely case of DE). Height and weight were measured by personnel.

Results

DE was more prevalent among girls (29.7%) relative to boys (12.2%), Arabs (25.1%) relative to Jews (19.5%), and older (25.3%) relative to younger (17.6%) adolescents. Arabs were more likely to eat dinner at home with parents/family (chi² = 10.75, p = .001), or not to eat dinner at all (chi² = 63.27, p < .001), while Jews were more likely to eat dinner alone (chi² = 5.37, p = .021) or to eat dinner out of the home (chi² = 67.65, p < .001). Logistic regressions (stratified by ethnicity and adjusted for gender, age, weight) revealed that family dinners acted as a protective factor against DE, relative to eating out of the home or relative to not eating dinner at all among both ethnic groups, and relative to eating dinner alone among Arabs.

Conclusion

There are differences between Arab and Jewish adolescents in terms of rates of yesterday’s family dinners and DE. Given that eating dinner with the family was linked with lower rates of DE, possible interventions to reduce DE may include educating parents of both Arab and Jewish adolescents regarding the importance of family meals.

Eating-Disordered Behavior in Adolescents: Associations with Body Image, Body Composition and Physical Activity

Eating disorders (EDs) represent a disparate group of mental health problems that significantly impair physical health or psychosocial functioning. The aim of this study was to present some evidence about the prevalence of eating-disordered behavior (EDB) in adolescents, and explore its associations with body image (BI), body composition (BC) and physical activity (PA) in this age group. Data from 780 adolescents participating in a health behavior in school-aged children (HBSC) study conducted in Slovakia in 2018 were used (mean age 13.5 ± 1.3; 56% boys). Differences in mean values of numerical indicators were evaluated using the independent samples t-test. Differences between nominal variables were assessed by the chi-square test. Pearson correlation was used to describe the associations between all the selected variables. EDB was positively screened in 26.7% (208/780) of adolescents, with a higher prevalence in girls (128/344, 37.2%) than in boys (80/436, 18.3%). Significantly higher means of BI, body weight (BW), body mass index (BMI), body fat mass (BFM), body fat percentage (BFP), body fat mass index (BFMI), fat free mass index (FFMI), and SCOFF questionnaire score (SCOFF QS) were found in those positively screened for EDB. Pearson correlation analysis revealed positive associations between EDB and BI, BW, BMI, BFM, BFP and BFMI. The prevalence of EDB is high in Slovak adolescents. Positive associations between EDB, BI, BMI and fat-related body composition parameters support the idea of a more integrated approach in EDs and obesity prevention and treatment. At the same time, gender differences suggest the need for considering gender-specific strategies aimed at girls and boys separately.

Alcohol consumption and risk for feeding and eating disorders in adolescence: The mediating role of drinking motives

BACKGROUND

A complex and bidirectional association has been assumed between feeding and eating disorders (FEDs) and alcohol consumption. Previous research has demonstrated that alcohol use among individuals with different forms of FEDs is more frequently motivated by two subtypes of internal drinking motives: coping and enhancement motives. Namely, these individuals might use alcohol primarily to regulate internal states, such as to mitigate negative emotions or enhance positive emotions.

OBJECTIVES

The present study investigated the mediating role of internal drinking motives on the association between risk for FEDs and alcohol consumption over the effects of relevant covariates, such as depressive symptoms or body mass index (BMI).

METHODS

Hungarian data of the European School Survey Project on Alcohol and Other Drugs (ESPAD) from 2015 were used. The final sample included responses from 5457 adolescents (50% males; mean age: 16.62 years). Validated self-report psychometric instruments assessed the level of alcohol use, depressive symptoms and risk for FEDs, and drinking motives.

RESULTS

Risk for FEDs presented a significant positive relationship with internal drinking motives and alcohol use. In the mediation analysis, a significant indirect effect was identified between risk for FEDs and alcohol use via internal drinking motives among females.

CONCLUSIONS

Results demonstrated that risk for FEDs was positively associated with internal drinking motives and alcohol use. An indirect effect of risk for FEDs on alcohol consumption via internal drinking motives was discriminated over the impact of depressive symptoms. However, the latter relationship was only found among females which may highlight the gender differences in the relationship between risk for FEDs and alcohol use.

Further development of the 12-item EDE-QS: identifying a cut-off for screening purposes

BACKGROUND

The Eating Disorder Examination - Questionnaire Short (EDE-QS) was developed as a 12-item version of the Eating Disorder Examination Questionnaire (EDE-Q) with a 4-point response scale that assesses eating disorder (ED) symptoms over the preceding 7 days. It has demonstrated good psychometric properties at initial testing. The purpose of this brief report is to determine a threshold score that could be used in screening for probable ED cases in community settings.

METHODS

Data collected from Gideon et al. (2016) were re-analyzed. In their study, 559 participants (80.86% female; 9.66% self-reported ED diagnosis) completed the EDE-Q, EDE-QS, SCOFF, and Clinical Impairment Assessment (CIA). Discriminatory power was compared between ED instruments using receiver operating characteristic (ROC) curve analyses.

RESULTS

A score of 15 emerged as the threshold that ensured the best trade-off between sensitivity (.83) and specificity (.85), and good positive predictive value (.37) for the EDE-QS, with discriminatory power comparable to other ED instruments.

CONCLUSION

The EDE-QS appears to be an instrument with good discriminatory power that could be used for ED screening purposes.

Eating Disorder Screening: a Systematic Review and Meta-analysis of Diagnostic Test Characteristics of the SCOFF

BACKGROUND

Eating disorders affect upwards of 30 million people worldwide and often go undertreated and underdiagnosed. The purpose of this systematic review and meta-analysis was to evaluate the diagnostic accuracy of the Sick, Control, One, Fat and Food (SCOFF) questionnaire for DSM-5 eating disorders in the general population.

METHOD

The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) were followed. A PubMed search was conducted among peer-reviewed articles. Information regarding validation of the SCOFF was required for inclusion. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool.

RESULTS

The final analysis included 25 studies. The validity of the SCOFF was high across samples with a pooled sensitivity of 0.86 (95% CI, 0.78-0.91) and specificity of 0.83 (95% CI, 0.77-0.88). Subgroup analyses were conducted to examine the impact of methodology, study quality, and clinical characteristics on diagnostic accuracy. Studies with the highest sensitivity tended to be case-control studies of young women with anorexia nervosa (AN) and bulimia nervosa (BN). Studies which included more men, included those diagnosed with binge eating disorder, and recruited from large community samples tended to have lower sensitivity. Few studies reported on BMI and race/ethnicity; thus, subgroups for these factors could not be examined. No studies used reference standards which assessed all DSM-5 eating disorders.

CONCLUSION

This meta-analysis of 25 validation studies demonstrates that the SCOFF is a simple and useful screening tool for young women at risk for AN and BN. However, there is not enough evidence to support utilizing the SCOFF for screening for the range of DSM-5 eating disorders in primary care and community-based settings. Further examination of the validity of the SCOFF or development of a new screening tool, or multiple tools, to screen for the range of DSM-5 eating disorders heterogenous populations is warranted.

Differential Item Functioning in Brief Instruments of Disordered Eating

Abstract. Most instruments for the assessment of disordered eating were developed and validated in young female samples. However, they are often used in heterogeneous general population samples. Therefore, brief instruments of disordered eating should assess the severity of disordered eating equally well between individuals with different gender, age, body mass index (BMI), and socioeconomic status (SES). Differential item functioning (DIF) of two brief instruments of disordered eating (SCOFF, Eating Attitudes Test [EAT-8]) was modeled in a representative sample of the German population ( N = 2,527) using a multigroup item response theory (IRT) and a multiple-indicator multiple-cause (MIMIC) structural equation model (SEM) approach. No DIF by age was found in both questionnaires. Three items of the EAT-8 showed DIF across gender, indicating that females are more likely to agree than males, given the same severity of disordered eating. One item of the EAT-8 revealed slight DIF by BMI. DIF with respect to the SCOFF seemed to be negligible. Both questionnaires are equally fair across people with different age and SES. The DIF by gender that we found with respect to the EAT-8 as screening instrument may be also reflected in the use of different cutoff values for men and women. In general, both brief instruments assessing disordered eating revealed their strengths and limitations concerning test fairness for different groups.

How Perfectionism and Eating Disorder Symptoms Contribute to Searching Weight-Loss Information on the Internet?

Background and Objectives: Eating disorder (ED) symptoms are a growing problem and modern technologies introduced a new and unexplored potential risk factor for vulnerable individuals. It is fairly common for women to use the Internet in order to find information about various weight-loss methods, but it was further questioned whether perfectionism and eating disorder symptomatology could be linked to this behavior. Materials and Methods: Participants were 228 women (Mean age = 30.5; SD = 9.43) recruited via social media, who provided responses on measures of perfectionism, eating disorder symptoms, and a short check-list measuring the frequency of online searching about five topics (food, diet, exercise, body appearance, and eating disorders). Results: Hierarchical multiple regression analysis showed that the BMI and Discrepancy subscale of APS-R significantly predicted online searching, along with eating disorder symptomatology. Moreover, mediation analyses resulted in a significant indirect effect, but not a direct effect, indicating that eating disorder symptomatology fully mediated the relationship between BMI and online searching, as well as between maladaptive perfectionism and online searching. Conclusion: These findings shed light on a high BMI and maladaptive perfectionism as potential risk factors for eating disorder-related behavior on the Internet. More attention to online-seeking behavior among women symptomatic of ED is warranted, and websites containing such topics should include information about professional help for eating disorder-symptomatic individuals.

Intuitive eating mediates the relationship between self-regulation and BMI - Results from a cross-sectional study in a community sample

Self-regulation is a dispositional skill of regulating attention and emotion to attain a certain goal. Poor self-regulation is associated with a higher body mass index (BMI) and is a risk factor for the development of obesity. Intuitive eating, an adaptive eating style characterized by eating in response to internal cues of hunger and satiety, is associated with a lower BMI. Using cross-sectional data, this study examined whether intuitive eating mediates the relationship between self-regulation and BMI in a community sample of adults. Participants (N = 530) completed the Self-Regulation Scale, the Intuitive Eating Scale-2 with its facets Unconditional Permission to Eat (UPE), Eating for Physical Rather Than Emotional Reasons (EPR), Reliance on Hunger and Satiety Cues (RHSC) and Body-Food Choice Congruence (B-FCC). They also self-reported their height and weight. Using percentile bootstrap resampling procedures, the simple mediation analysis showed an indirect relationship between self-regulation and BMI through intuitive eating. The multiple mediation analysis revealed that EPR and B-FCC, but not UPE and RHSC, mediated the relationship between self-regulation and BMI. Intuitive eating seems to play an important intermediating role in the relationship between self-regulation and BMI. Regarding weight management interventions, it could be useful to promote intuitive eating, especially for individuals with low self-regulation. Prospective studies are needed to explore the causal and temporal relationships among self-regulation, intuitive eating and BMI.

Sociodemographic correlates of eating disorder subtypes among men and women in France, with a focus on age

Background

On the population level, the association of age and other sociodemographic factors with eating disorders (ED) is unclear.

Methods

We used cross-sectional data from the French general population-based NutriNet-Santé e-cohort (n=49 603 adults; 76.3% women; mean age=50.4±14.6 years). ED were evaluated in 2014 with the 5-item SCOFF screening questionnaire and the Expali algorithmic tool. Likely cases of restrictive, bulimic, hyperphagic and other ED were the dependent variables. Age, marital status, education, occupation, physical activity and smoking were the independent variables. Associations were estimated via gender-stratified multivariable polytomous logistic regression.

Results

Among women, age displayed inverse linear associations with both restrictive and bulimic ED, underscoring 18–25 years as the most vulnerable period (adjusted OR=3.37, 95% CI: 2.24 to 5.08 for restrictive ED; adjusted OR=2.98, 95% CI: 2.37 to 3.74 for bulimic ED, respectively). A similar association was observed in men regarding bulimic ED. In women, age was not associated with hyperphagic ED for which living alone, low education, low physical activity, being a homemaker/disabled/unemployed/retired, a manual worker or a former/current smoker had increased importance. In men, 18–39 years emerged as the least vulnerable period regarding hyperphagic ED (adjusted OR=0.74, 95% CI: 0.56 to 0.99). Across gender, having postsecondary education had significant inverse associations with all except restrictive ED, whereas being a student had a significant positive association with restrictive ED.

Conclusions

The findings support gender-specific associations of age with four ED subtypes and could inform future prevention initiatives targeting specific ED among specific age groups.

Disordered eating in a Swedish community sample of adolescent girls: subgroups, stability, and associations with body esteem, deliberate self-harm and other difficulties

BACKGROUND

The developmental study of subtypes of disordered eating (DE) during adolescence may be relevant to understand the development of eating disorders. The purpose of the present study was to identify subgroups with different profiles of DE in a community sample of adolescent girls aged 13-15 years, and to study the stability of these profiles and subgroups over a one-year interval in order to find patterns that may need to be addressed in further research and prevention.

METHODS

Cluster analysis according to the LICUR procedure was performed on five aspects of DE, and the structural and individual stability of these clusters was analysed. The clusters were compared with regard to BMI, body esteem, deliberate self-harm, and other kinds of psychological difficulties.

RESULTS

The analysis revealed six clusters (Multiple eating problems including purging, Multiple eating problems without purging, Social eating problems, Weight concerns, Fear of not being able to stop eating, and No eating problems) all of which had structurally stable profiles and five of which showed stability at the individual level. The more pronounced DE clusters (Multiple eating problems including/without purging) were consistently associated with higher levels of psychological difficulties and lower levels of body esteem. Furthermore, girls that reported purging reported engaging in self-harm to a larger extent.

CONCLUSIONS

Subgroups of 13-15 year old girls show stable patterns of disordered eating that are associated with higher rates of psychological impairment and lower body esteem. The subgroup of girls who engage in purging also engage in more deliberate self-harm.

Identification of eating disorder symptoms in Danish adolescents with the SCOFF questionnaire

BACKGROUND

Eating disorders often develop in adolescence and, therefore, instruments are needed that are useful to detect risk behaviour in young people. The SCOFF is a 5-item screening instrument, named SCOFF as an acronym of keywords from the questions. It has been used widely in adult samples, but studies that evaluate the scale in adolescents are missing.

AIMS

The aim of this study was to test the psychometric properties of the SCOFF in adolescents aged 11-20 years and for the first time validate the questionnaire in Danish.

METHODS

A total of 184 adolescents completed the Danish version of the SCOFF and sub-scales from the Eating Disorder Inventory (EDI-3). The sample consisted of 87 patients (mean age = 16) from a specialized eating disorder department in the Region of Southern Denmark and 97 healthy adolescents (mean age = 17) from Danish primary and high schools.

RESULTS

It was found that the reliability of the SCOFF was acceptable, and that cut-off 2 is useful to detect those with potential eating disorder pathology. Item 3 (weight loss) correlated poorly with EDI-3 sub-scales and might be reformulated by addressing the intentionality behind weight loss (due to unhappiness with body) rather than a specific amount of weight loss (1 stone), because this could have somatic reasons.

CONCLUSIONS

The SCOFF is a very easily applicable questionnaire, which may fulfil the necessary psychometric properties for detection of ED symptoms in Danish adolescents. Before general screening can be recommended, conditions regarding benefits and potential adverse effects still remain to be addressed.
