Emotion Regulation and Loss of Control Eating in Community-Based Adolescents

Prenatal loss of control eating is associated with psychiatric symptoms and distress among individuals with elevated BMI

PURPOSE

Loss of control while eating (LOC) or feeling unable to control the amount or type of food consumed during an eating episode, is the core psychopathology in binge eating disorders. Yet, the impact of LOC on other psychiatric symptoms during pregnancy is not known. This study evaluated the contribution of prenatal LOC to psychological distress and disordered eating attitudes.

METHODS

Pregnant individuals with BMI ≥ 25 (N = 312) recruited for a perinatal health promotion trial self-reported past-month LOC; eating, shape, and weight concerns; prenatal depressive symptoms, anxiety, and stress. Propensity scores were used to reduce bias associated with cross-sectional data.

RESULTS

Overall, 34.3% (n = 107) reported LOC. Individuals with prenatal LOC, relative to those without, endorsed more eating disorder symptoms (ps<.001) as well as more symptoms of depression (7.1± 0.3 vs. 5.4± 4.9) and anxiety (38.1 ± 11.7 vs. 33.4 ± 11.7) and greater perceived stress (25.0 ± 7.9 vs. 22.0± 9.9, ps<.001). LOC frequency was associated with significantly more prenatal psychological distress, beyond the effect of other factors that increase the likelihood of LOC. (ps<.005).

CONCLUSIONS

Among individuals with elevated BMI, prenatal LOC is common and relates to eating disorder and other psychiatric symptoms. Prenatal LOC may represent a behavioral mechanism for improved psychological health.

Interventions for improving psychological symptoms in binge eating disorder (BED) and loss of control (LOC) eating in childhood and adolescence: a systematic scoping review

BACKGROUND

Despite reports of high incidence and prevalence, relatively few studies have investigated outcomes for children and adolescents with binge eating disorder (BED) and loss of control (LOC) eating. This study aimed to scope the available literature systematically.

METHODS

A systematic scoping review methodology was implemented. Five databases (Medline, PsycInfo, Embase, CENTRAL and Scopus) were searched on the 23rd of August 2024 for relevant peer-reviewed journal articles and dissertations. No beginning time point was specified, and the end time point was chosen as the 23rd of August 2024. Restrictions were placed on age (under 20), diagnosis (BED, LOC eating) and study design (quantitative).

RESULTS

Ten quantitative studies were identified: eight randomised controlled trials and two case series. Outcome data for 2400 young people were synthesised. Most studies (70%) had a sample size of fewer than 100 participants. Treatment modalities were heterogeneous and included psychological therapies such as cognitive behavioural therapy (CBT), dialectical behavioural therapy (DBT), interpersonal therapy (IPT) and group schema therapy. One study examined the role of medication. The results suggested that six different treatment modalities (CBT (group and individual), IPT, DBT, family-based IPT (FB-IPT), and medication) were associated with a reduction in the number of binge eating episodes and LOC eating. In terms of other psychological aspects such as depression, anxiety and self-esteem, the data were sparse, and it was difficult to draw meaningful conclusions.

CONCLUSIONS

The findings highlight a paucity of evidence-based interventions in this area for young people with BED and LOC eating. This is an emerging and important field in child and adolescent eating disorders as it is now ten years since BED was introduced into the DSM-V with prevalence estimates higher than other eating disorders in this population. As the onset of binge eating often occurs in late childhood or adolescence there is a role for early intervention. Further research into the efficacy of different therapeutic options for this age group is needed. In this review, the authors searched for studies where treatment for binge eating disorder (BED) or loss of control eating (LOC) in young people (under 20 years old) had been trialled. They wanted to see which treatments could improve the mental health of young people with these conditions. To ensure that as many studies as possible were included, five different databases were searched. Ten studies were found and the majority of these were small studies with less than 100 participants. Nine of the studies investigated the role of talking therapies, for example, cognitive behavioural therapy and one study examined how medication helped. The talking therapies used in each of the nine studies were varied. The authors found that, on the whole, talking therapy and medication helped with the number of binge eating episodes and LOC eating but it was less easy to understand if they helped with depression and anxiety which are both commonly associated with BED and LOC eating. The results of this review show that more research is needed into this area as few studies were found and BED and LOC eating are becoming more frequently diagnosed in young people.

Emotion regulation difficulties and disordered eating in adolescents and young adults: a meta-analysis

Eating disorders and difficulties in regulating emotions are frequent among adolescents and serve as risk factors for several health issues. Nonetheless, the relationship remains ambiguous; investigating this connection will not only elucidate the associations between the two illnesses. Nevertheless, it will offer theoretical backing for interventions targeting the pertinent illnesses. This study seeks to examine the relationship between emotion management and disordered eating while assessing the moderating influences of Body Mass Index (BMI) and gender to enhance future interventions for eating disorders. We conducted a search in April 2024 and updated it in November of the same year, encompassing literature published from 2010 to November 2024 across five English and Chinese databases. A random effects model was conducted to analyze research outcomes. This meta-analysis encompassed 23 research, demonstrating a medium positive connection between difficulties in regulating emotions and disordered eating (r = 0.418). Subgroup analyses revealed medium positive relationships between difficulties in emotion regulation and disordered eating (r = 0.428), loss-of-control eating disorders (r = 0.410), and emotional eating (r = 0.370). The meta-regression analysis revealed that gender significantly moderates this association, but BMI does not. The present study indicated that adolescents or young adults with difficulties in emotional regulation are susceptible to displaying symptoms of eating disorders in both sexes; however, in females, emotional regulation issues are more likely to be associated with eating disorders. Future longitudinal or experimental researches are needed to reveal the causal relationship between the two variables and the similarities and variations between genders during adolescence and early adulthood.

Emotion regulation as a transdiagnostic construct across the spectrum of disordered eating in adolescents: A systematic review

OBJECTIVE

This systematic review aimed to understand the role of emotion regulation (ER) across the spectrum of disordered eating behaviors and attitudes in adolescents.

METHOD

A literature search was conducted using the PubMed, Scopus, and Web of Science databases, and 8381 articles were extracted. After removing duplicates and screening, data from 50 articles involving 31,591 participants from 18 countries were included.

RESULTS

Consistent associations between difficulties in ER/maladaptive ER and overeating (but not restrictive) behaviors/attitudes were found among adolescents without an eating disorder diagnosis. In contrast, in adolescents with eating disorders, ER difficulties were associated with restrictive-, compensatory- and overeating-type eating disorders. More difficulties in ER were found among adolescents with eating disorder diagnoses (i.e., anorexia nervosa, bulimia nervosa, or binge eating disorder) than among their healthy/normal-weight peers. Nonetheless, difficulties in ER abilities and in the implementation of ER strategies were greater in adolescents with anorexia nervosa or bulimia nervosa than in adolescents with binge eating disorder. Finally, concerning the role of adaptive ER, although fewer adaptive ER strategies were consistently found in adolescents with a diagnosis of anorexia nervosa than in healthy controls, the results in community samples were less consistent.

DISCUSSION

Overall, ER was associated with disordered eating behaviors/attitudes and eating disorder diagnoses, supporting the transdiagnostic role of ER in the spectrum of eating psychopathology. Fewer consistent findings were found across the weight spectrum, specifically at the higher end (overweight/obesity). These results highlighted the role of different ER abilities and strategies and the relevance of maladaptive (vs. adaptive) ER in understanding disordered eating. The findings also set the context for developing specific ER-based interventions across the spectrum of disordered eating behaviors and attitudes.

Factors associated with prospective changes in weight control intentions among adolescents

INTRODUCTION

The present study examined predictors of negative changes in weight control intentions from before to during the COVID-19 pandemic among adolescents.

METHODS

Participants were Canadian secondary school students enrolled in the COMPASS study and had completed self-report surveys before (T1; 2018/2019 and/or 2019/2020 school year) and during (T2; 2020/2021 and/or 2021/2022) the COVID-19 pandemic (N = 11,869, Mage ± SD = 13.79 years old ± 1.15, 52.89% girls, 45.30% boys, 1.81% gender diverse). Demographic, interpersonal, behavioral, and psychological predictors of weight control intention change from T1 (stay the same weight, not doing anything about weight) to T2 (lose weight, gain weight) were tested using multilevel logistic regressions.

RESULTS

Over one-third (37.0%) of adolescents who reported wanting to stay the same weight at T1 changed their intention to lose or gain weight at T2, as did 28.5% of adolescents who reported not wanting to do anything about their weight at T1. Changing weight control intention from "not doing anything about weight" at T1 to weight gain/loss at T2 was associated with resistance training, emotion dysregulation, bullying, social media use, and gender. Changing weight control intention from "stay the same weight" at T1 to weight gain/loss at T2 was associated with gender, perceived financial comfort, social media use, and flourishing.

CONCLUSIONS

Results highlight the prevalence of maladaptive weight control intention changes among adolescents, and elucidate related behavioral, interpersonal, demographic, and psychological factors. Findings can inform targeted intervention and prevention strategies to disrupt maladaptive changes in weight control intentions among high-risk subgroups.

Tension and disordered eating behaviors in the daily lives of adolescents and young adults from the general population: Associations and moderating role of trait emotion regulation

Experiences of tension and difficulties in emotion regulation have been linked to eating pathology in clinical samples and are targeted in respective treatment approaches. The present study aimed to investigate the impact of tension on engagement in disordered eating behaviors (DEBs) and potential moderating effects of trait emotion regulation in young people from the general population. A subsample of 971 adolescents and young adults from an epidemiological cohort study reported on levels of tension and four different DEBs (skipping eating, restrained eating, eating large amounts of food, loss-of-control-eating) via ecological momentary assessment (EMA), as well as on trait emotion regulation via questionnaire. In multilevel models, momentary tension did not predict levels of subsequent DEBs. However, higher average levels of tension across the EMA period predicted higher levels of all DEBs. No interactions with emotion regulation emerged. Individuals experiencing overall higher levels of tension appear to be more prone to engaging in DEBs.

Children with lower ratings of executive functions have a greater response to the portion size effect

Deficits in executive functions (EFs), a set of cognitive processes related to self-regulation, are associated with the development of obesity. Prior studies from our group showed that lower food-cue related activation in brain regions implicated in self-regulation was related to a larger portion size effect. We tested the hypothesis that lower EFs in children would be positively related to the portion size effect. Healthy weight children aged 7-8 y (n = 88), who varied by maternal obesity status, participated in a prospective study. At baseline, the parent primarily in charge of feeding completed the Behavior Rating Inventory of Executive Function (BRIEF2) to assess child EFs, including Behavioral (BRI), Emotional (ERI), and Cognitive (CRI) indices. At 4 baseline sessions, children consumed meals in which the portion sizes of foods (pasta, chicken nuggets, broccoli, and grapes) varied by visit (total meal weight of 769, 1011, 1256, or 1492g). Intake increased with increasing portions in a linear trajectory (p < 0.001). EFs moderated the portion size effect such that lower BRI (p = 0.003) and ERI (p = 0.006) were associated with steeper increases in intake as portions increased. As amount of food increased, children in the lowest functioning tertiles for BRI and ERI increased intake by 35% and 36%, respectively, compared to children in the higher tertiles. Increases in intake among children with lower EFs were for higher- but not lower-energy-dense foods. Thus, in healthy weight children who varied by obesity risk, lower parentally reported EFs were associated with a larger portion size effect, and these results were independent of child and parent weight status. Therefore, EFs may be target behaviors that could be strengthened to help children moderate excess intake in response to large portions of energy-dense foods.

Autonomic indices and loss-of-control eating in adolescents: an ecological momentary assessment study

BACKGROUND

Loss-of-control (LOC) eating commonly develops during adolescence, and it predicts full-syndrome eating disorders and excess weight gain. Although negative emotions and emotion dysregulation are hypothesized to precede and predict LOC eating, they are rarely examined outside the self-report domain. Autonomic indices, including heart rate (HR) and heart rate variability (HRV), may provide information about stress and capacity for emotion regulation in response to stress.

METHODS

We studied whether autonomic indices predict LOC eating in real-time in adolescents with LOC eating and body mass index (BMI) ⩾70th percentile. Twenty-four adolescents aged 12-18 (67% female; BMI percentile mean ± standard deviation = 92.6 ± 9.4) who reported at least twice-monthly LOC episodes wore biosensors to monitor HR, HRV, and physical activity for 1 week. They reported their degree of LOC after all eating episodes on a visual analog scale (0-100) using a smartphone.

RESULTS

Adjusting for physical activity and time of day, higher HR and lower HRV predicted higher self-reported LOC after eating. Parsing between- and within-subjects effects, there was a significant, positive, within-subjects association between pre-meal HR and post-meal LOC rating. However, there was no significant within-subjects effect for HRV, nor were there between-subjects effects for either electrophysiologic variable.

CONCLUSIONS

Findings suggest that autonomic indices may either be a marker of risk for subsequent LOC eating or contribute to LOC eating. Linking physiological markers with behavior in the natural environment can improve knowledge of illness mechanisms and provide new avenues for intervention.

Binge-Eating Precursors in Children and Adolescents: Neurodevelopment, and the Potential Contribution of Ultra-Processed Foods

Binge-eating disorder (BED) is a highly prevalent disorder. Subthreshold BED conditions (sBED) are even more frequent in youth, but their significance regarding BED etiology and long-term prognosis is unclear. A better understanding of brain findings associated with BED and sBED, in the context of critical periods for neurodevelopment, is relevant to answer such questions. The present narrative review starts from the knowledge of the development of emotional self-regulation in youth, and the brain circuits supporting emotion-regulation and eating behaviour. Next, neuroimaging studies with sBED and BED samples will be reviewed, and their brain-circuitry overlap will be examined. Deficits in inhibition control systems are observed to precede, and hyperactivity of reward regions to characterize, sBED, with overlapping findings in BED. The imbalance between reward/inhibition systems, and the implication of interoception/homeostatic processing brain systems should be further examined. Recent knowledge of the potential impact that the high consumption of ultra-processed foods in paediatric samples may have on these sBED/BED-associated brain systems is then discussed. There is a need to identify, early on, those sBED individuals at risk of developing BED at neurodevelopmental stages when there is a great possibility of prevention. However, more neuroimaging studies with sBED/BED pediatric samples are needed.

Emotion regulation difficulties are associated with loss-of-control eating dependent on degree of narcissistic traits in college students

Loss-of-control eating (LOCE) is highly prevalent in college students and may be driven by enduring personality traits. Narcissism is often conceptualized with two broad domains: grandiose and vulnerable. The association between narcissism and LOCE has not been directly assessed, nor the potential influence of emotion regulation deficits, which are differentially associated with grandiosity and vulnerability. This study hypothesized an association between vulnerable narcissism and LOCE in college students by way of emotion regulation difficulties, extending prior findings. Participants (n = 704) completed a survey on pathological eating and body image disturbance, emotion regulation difficulties, and narcissistic traits. Results supported a full mediation effect, such that vulnerable narcissism was positively associated with LOCE by way of emotion regulation difficulties. Present findings suggest the mechanism primarily predictive of LOCE is emotion regulation difficulties, and predisposition to deficits in emotion regulation associated with vulnerable narcissism may increase the odds of LOCE. Additionally, it was noted that grandiose narcissism evinced a fully mediated inverse association with LOCE. Clinical implications and directions for future research are discussed.

Experiences of loss of control eating in women after bariatric surgery: A qualitative study

OBJECTIVE

Loss of control (LOC) eating following bariatric surgery remains insufficiently understood, reflected in a lack of clear conceptualization, valid measurements, and effective treatments. This study explored patients' perspectives on LOC eating post-bariatric surgery, focusing on the relevance of the Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) indicators of impaired control, and patients' experiences before (precipitating factors), during (eating patterns, perpetuating factors), and after the episodes (strategies used to stop eating).

METHODS

This was a qualitative study using descriptive phenomenology. Participants were adults who have undergone gastric bypass or sleeve gastrectomy and self-reported recent LOC eating. Data were collected by semi-structured interviews and analyzed using a combined inductive and deductive approach.

RESULTS

Participants were all women (N = 15; age: 34.5 ± 9.2 years). Results suggested that (1) except for feeling disgusted, guilty, or depressed after eating, other DSM-5 indicators did not seem to be highly relevant to this bariatric cohort; (2) LOC eating could occur across contexts, with food access, boredom, and food craving being consistent triggers; (3) the food amount consumed during a LOC episode was not necessarily considered excessive; (4) "mindlessness" and "satisfying hedonic, physiological, and mental needs" were the main perpetuating factors of LOC eating; and (5) self-talk and distracting attention were the most adopted strategies to stop eating.

DISCUSSION

Study findings have implications concerning the conceptualization, measurement, and intervention of LOC eating among bariatric patients. For example, results suggested the need for more data to determine the appropriate indicators of LOC eating and the inclusion of boredom as an intervention target in bariatric patients.

PUBLIC SIGNIFICANCE

Loss of control (LOC) eating is characterized by a sense of being unable to stop while eating. LOC eating is prevalent in patients who have undergone weight loss surgery and is associated with worse surgical outcomes. This qualitative study that explored post-bariatric surgery patients' experiences of LOC eating will inform efforts to better assess and intervene in this disordered eating behavior, thus ultimately optimizing patients' health following weight loss surgery.

A predictor of emotional eating in adolescents: Social anxiety

This descriptive, cross-sectional study was conducted to determine the effect of social anxiety on emotional eating in adolescents. The sample consisted of 1027 adolescents between aged 14-18 studying in the 9-12th grades of the high schools in the Central Anatolia Region in the 2018-2019 academic year. Ethics Committee and institutional permission was obtained in this study, data were collected by a questionnaire, the Social Anxiety Scale for Children-Revised (SASC-R), and The Emotional Eating Scale Adapted for Use in Children and Adolescents (EES-C). Data were analyzed using descriptive statistics, Mann-Whitney U test, Kruskal-Wallis test and simple linear regression analysis. Adolescents had a mean SASC-R and EES-C score of 43.49 ± 16.56 and 61.93 ± 18.68, respectively. It was found that there was a relationship between EES-C mean scores and SASC-R mean scores, and they explained 35.0 % of the scores they got from the EES-C scale (p < 0.05). In conclusion, adolescents had moderate emotional eating and social anxiety. The higher the social anxiety, the higher the emotional eating. School personnel, parents and healthcare professionals need education about social anxiety and eating disorders in adolescents in order to detect symptoms early and intervene to better support adolescents struggling with social anxiety.

Subclinical binge eating symptoms in early adolescence and its preceding and concurrent factors: a population-based study

OBJECTIVE

Binge eating, loss of control eating and overeating often develop during late childhood or early adolescence. Understanding the presentation of binge eating as early as symptoms manifest and its preceding and concurrent factors is essential to hamper the development of eating disorders. This study examined the prevalence, concurrent and preceding factors (e.g. compensatory behaviors, emotional and behavioral problems) of subclinical binge eating symptoms in early adolescence.

METHODS

Data from the population-based Generation R Study were used (n = 3595). At 10 years and 14 years, preceding and concurrent factors including eating behaviors, body dissatisfaction, emotional and behavioral problems and body composition were assessed. At 14 years, 3595 adolescents self-reported on binge eating symptoms in the past 3 months and were categorized into four groups: no symptoms (n = 3143, 87.4%), overeating only (n = 121, 3.4%), loss of control (LOC) eating only (n = 252, 7.0%) or binge eating (i.e. both, n = 79, 2.2%).

RESULTS

In total, 452 (12.6%) young adolescents reported subclinical binge eating symptoms. Those who reported LOC eating and binge eating showed most compensatory behaviors (e.g. hide or throw away food, skipping meals). Concurrent emotional and behavioral problems, body dissatisfaction, more emotional-, restrained- and uncontrolled eating, and a higher BMI were associated with subclinical binge eating symptoms. Preceding self-reported emotional and behavioral problems, body dissatisfaction, more restrained eating and higher BMI (both fat mass and fat-free mass) at 10 years were associated with LOC eating and binge eating, but not with overeating.

DISCUSSION

Among young adolescents, subclinical binge eating symptoms were common. Considering the high prevalence of LOC eating, and the overlapping preceding and concurrent factors of LOC eating and binge eating compared to overeating, LOC eating seems to be a key symptom of binge eating in early adolescence.

Exploring Correlates of Loss of Control Eating in a Nonclinical Sample

OBJECTIVE

Loss of control (LOC) eating has been directly related to the core aspects of the psychopathology of eating disorders and to different dimensions of emotion and behavior regulation and self-criticism. This study investigates a model representing the interplay between these dimensions to understand LOC eating among a nonclinical sample.

METHODS

A total of 341 participants, recruited in a college campus (mean age 23.21, SD = 6.02), completed a set of self-report measures assessing LOC eating, weight suppression, psychopathology of eating disorders, depression, negative urgency, emotion regulation difficulties, and self-criticism. Path analysis modeling tested a hypothesized model with 3 paths for LOC eating as follows: (1) psychopathology of eating disorders; (2) emotion and behavior regulation; and (3) interplay between these paths.

RESULTS

We found goodness-of-fit indexes to our data: χ2 = 17.11, df = 10, Comparative Fit Index (CFI) = 0.99, Tucker-Lewis index (TLI) = 0.98, Root Mean Square Error Approximation (RMSEA) = 0.045, Standardized Root Mean Square Residual (SRMR) = 0.041, suggesting that: (1) participants with higher weight suppression showed higher degrees of the psychopathology of eating disorders, which was linked to higher levels of LOC eating; (2) self-criticism was a mediator between emotion regulation and depression/negative urgency; (3) self-criticism was a mediator between emotion regulation and disorder eating, which was significantly associated with LOC eating via increased negative urgency.

CONCLUSION

Our model shows that LOC eating occurs for individuals with the psychopathology of higher eating disorders who experience depressive symptoms and act rashly under distress for their inability to cope adequately with negative feelings of self-devaluation. These findings point to the importance of negative self-evaluations and feelings of inadequacy or worthlessness to understand LOC eating among college students.

Correlates of interpersonal emotion regulation problems in Loss of Control eating (LOC) in youth: study protocol of the combined online and App based questionnaire, laboratory and randomized controlled online intervention i-BEAT trial

BACKGROUND

Binge Eating Disorder (BED) represents a common eating disorder associated with marked health impairments. A subclinical variant, loss of control eating (LOC) is prevalent in youth. LOC is associated with similar mental distress as full-blown BED, increases the risk to develop a BED and promotes continuous weight gain. The etiology of LOC is not yet fully understood and specialized treatment for youth is scarce.

METHODS

The i-BEAT study includes a cross-sectional and longitudinal online questionnaire study (N = 600), an App based daily-life approach and a laboratory virtual reality study in N = 60 youths (14-24 years) with and without LOC as well as a controlled randomized online treatment trial to investigate the feasibility, acceptance and efficacy of a CBT and an interpersonal emotion regulation module for youth (N = 120). The primary outcomes include self-reported as well as measured (heart rate variability, gaze behavior, reaction times in stop signal task) associations between emotion regulation problems (such as dealing with RS), psychological impairment and binge eating in a healthy control group and youth with LOC. Secondary outcomes encompass general eating disorder pathology, social anxiety, body mass index, hyperscanning behavior and therapists' rating of patients' condition pre and post treatment. Epigenetic correlates of RS are assessed in healthy controls and youth with LOC and explored before and after treatment.

DISCUSSION

The expected findings will specify the role of interpersonal emotion regulation problems such as coping with the experience of social exclusion and rejection sensitivity (RS) in LOC and clarify, whether including a training to cope with RS adds to the efficacy of a cognitive behavioral treatment (CBT).

Emotion dysregulation and pediatric obesity: investigating the role of Internet addiction and eating behaviors on this relationship in an adolescent sample

OBJECTIVE

The first aim was to investigate whether there was a mediator role of Internet addiction or uncontrolled/emotional eating on the association between emotion dysregulation and body mass index-standard deviation score (BMI-SDS). The second aim was to detect which of these variables (emotion dysregulation, Internet addiction, and uncontrolled/emotional eating) significantly affect the presence of obesity (OB).

METHODS

A total of 123 adolescents (OB (n = 65, 57% of girls, mean age = 15 ± 1.9, BMI percentile between 95 and 99) and healthy control (HC) (n = 58; 53% of girls, mean age = 15.5 ± 1.8, BMI percentile between 1 and 84) aged between 11 and 18 were recruited. Difficulties in Emotion Regulation Scale (DERS) and Internet Addiction Test (IAT) were completed by adolescents. Uncontrolled and emotional eating behaviors were measured by Three Factors Eating Questionnaire (TFE-Q)'s sub-domains.

RESULTS

There was no significant direct effect of DERS on BMI-SDS, whereas the indirect effect of DERS on BMI-SDS which was mediated by both IAT and TFE-Q was statistically significant. In logistic regression analysis, an increase by 1 point in DERS total score escalated the odds of being OB by 2%. Moreover, a 22-fold increased risk of OB has been detected in moderate/severe Internet addiction compared to no addiction.

CONCLUSION

This cross-sectional study showed that the association between emotion dysregulation and BMI-SDS was totally mediated by internet addiction and uncontrolled/emotional eating. In addition, emotion dysregulation and Internet addiction were significant determinants of OB. A prospective study is needed to detect the causal relationship between these variables.

Work Environment, Mental Health, and Eating Behavior in Mexican Nurses

Nursing staff in public hospitals face highly demanding working conditions, which are related to mental health and eating problems. The current study aimed to identify the most frequent work characteristics associated with mental health problems and eating behavior in nursing staff. A cross-sectional study was performed on a random sample of 190 nurses at a specialized hospital in Mexico City. Work characteristics, mental health problems (stress, depression, and anxiety), emotional eating, and loss-of-control eating were measured using standardized scales. Associations among relevant work variables and mental health and eating behavior were assessed using logistic regression models adjusted for sociodemographic characteristics. High prevalence of stress (28%), depression (35%), anxiety (33%), emotional eating (27%), and loss-of-control eating (38%) were found. These mental health problems have been associated with variables related to work overload, little appreciation of work, and exposure to the suffering and death of patients.

Psychometric Properties of the Spanish Version of the Cognitive Emotional Regulation Difficulties Questionnaire (CERQ) in Higher Education Students in Times of Covid-19

The Cognitive Emotion Regulation Questionnaire (CERQ) is an instrument developed to assess the cognitive strategies of emotional regulation used by people after experiencing a negative event. The present study aimed to validate the Spanish version of the CERQ in students of the University of Granada (Spain) during the Covid-19 homebound. An online scale was developed and applied based on the Spanish version of the CERQ-S36, consisting of 36 items structured around nine cognitive strategies. Using a mixed sampling, the scale was applied to 450 students from different degree programmes. Regarding the psychometric results of the scale, firstly, in relation to reliability as internal consistency, we found that the scale applied to University students in a Covid-19 setting is highly stable. Secondly, in reference to concurrent criterion validity, we can conclude that the items individually measure the same as the total scale (taken as internal criterion), and thirdly and finally, in relation to construct validation, the two factor analyses implemented, one exploratory and the other confirmatory in nature, conform a factor structure of latent dimensions identical to the original one. In conclusion, the results obtained as a whole suggest that the CERQ-S36 scale could be useful for assessing cognitive coping in University populations in times of crisis. In situations such as the current global emergency due to the presence of Covid-19, the scale is useful for understanding emotional regulation strategies. More studies should be carried out with this scale to find out how emotions influence and what consequences they have on the health and psychological functioning of University students in times of social crisis.

Social-emotional functioning in young people with symptoms of eating disorders: A gender inclusive analogue study

INTRODUCTION

Contemporary models of eating disorders (EDs) suggest that EDs are maintained by social-emotional difficulties. However, supporting evidence is derived largely from female, clinic-based samples. This study, which refrained from gender specific inclusion criteria, aimed to improve understanding of social-emotional functioning in a large community-based analogue sample of young adults aged 16-26.

METHODS

Five hundred and forty-four participants (85.1% female; mean age 21, SD = 4.3) completed the Eating Attitudes Test, Clinical Outcomes in Routine Evaluation, Difficulties in Emotion Regulation Scale, Social Phobia Inventory, Revised Social Anhedonia Scale, Toronto Alexithymia Scale, and the Reading the Mind in the Eyes Task.

RESULTS

One hundred and sixty-four participants scored over the EAT-26 clinical cutoff, and a two-way multivariate analysis of covariance found a medium-sized, statistically significant main effect of group on social-emotional functioning (F(5, 530) = 6.204, p ≤ .001, Wilks' Λ = 0.945, d = 0.48.), suggesting that individuals with significant ED symptoms found it more challenging to notice, label, and regulate emotions in themselves and recognize emotions in others. Gender did not significantly impact social-emotional functioning (F(10, 1,060) = 0.556, p = .850, Wilks' Λ = 0.990), and there was no significant group by gender interaction (F(10, 1,060) = 0.688, p = .737, Wilks' Λ = 0.987).

CONCLUSION

These data suggest that the social-emotional difficulties, particularly with emotion recognition and regulation, present in clinical samples are also evident in young people of all genders with significant disordered eating. Future work could aim to recruit an even more gender-diverse community sample to further elucidate social-emotional functioning in individuals in the community with significant disordered eating.

Emotional Regulation and Overeating Behaviors in Children and Adolescents: A Systematic Review

The worldwide prevalence of obesity has dramatically increased, mostly in children and adolescents. The Emotional Eating theoretical model has proposed that the failure in emotional regulation could represent a risk factor for establishing maladaptive overeating behavior that represents an inadequate response to negative emotions and allows increasing body-weight. This systematic review investigates the relationship between overeating and both emotional regulation and emotional intelligence in childhood and adolescence, considering both cross-sectional and longitudinal studies. Moreover, another goal of the review is evaluating whether emotional regulation and emotional intelligence can cause overeating behaviors. The systematic search was conducted according to the PRISMA-statement in the databases Medline, PsychArtcles, PsychInfo, PubMed, Scopus, and Web of Sciences, and allows 484 records to be extracted. Twenty-six studies were selected according to inclusion (e.g., studies focused on children and adolescents without clinical conditions; groups of participants overweight or with obesity) and exclusion (e.g., studies that adopted qualitative assessment or cognitive-affective tasks to measure emotional variables; reviews, commentary, or brief reports) criteria detailed in the methods. Cross-sectional studies showed a negative association between emotional regulation and overeating behavior that was confirmed by longitudinal studies. These findings highlighted the role of maladaptive emotion regulation on overeating and being overweight. The relationship between these constructs in children and adolescents was consistent. The results indicated the complexity of this association, which would be influenced by many physiological, psychological, and social factors. These findings underline the need for further studies focused on emotion regulation in the development of overeating. They should analyze the mediation role of other variables (e.g., attachment style, peer pressure) and identify interventions to prevent and reduce worldwide overweight prevalence.

Personality correlates of eating pathology severity and subtypes in The National Comorbidity Survey Adolescent Supplement

OBJECTIVE

We examined how personality traits are associated with eating pathology (EP) across a range of severities and symptom subtypes.

METHOD

The National Comorbidity Survey Adolescent Supplement (N = 10,148) was used to compare personality across severities (i.e., clinical Eating Disorders [EDs], subclinical disordered eating, preclinical weight concerns, or no weight/EP [no W/EP]), subclinical subtypes (i.e., Binge Eating Only, Binge-Purge, Binge-Restrict, Restrict-Purge, or no W/EP), and clinical subtypes (i.e., Anorexia Nervosa [AN]), Bulimia Nervosa [BN], Binge Eating Disorder [BED], internalizing disorders, or no ED or internalizing disorder) of EP.

RESULTS

More severe EP was associated with more extreme personality trait endorsements. Impulsivity-related traits did not consistently distinguish binge eating/purging from restricting subtypes, although behavioral disinhibition differentiated adolescents with BN or BED from AN.

CONCLUSION

Personality traits related to affectivity and impulsivity were more consistently associated with severity rather than subtype of EP.

Examining simultaneous associations of four emotion regulation strategies with abnormal eating behaviors/attitudes in early adolescents

Previous research has suggested that emotion regulation strategies (ERSs) are associated with abnormal eating behaviors and attitudes (AEBs). Available data have demonstrated that frequent rumination, a major maladaptive ERS, is associated with elevated AEBs, whereas adaptive ERSs, such as problem-solving and cognitive reappraisal, showed negative associations with AEBs. Most previous studies examined the association of a single ERS with AEBs. Therefore, any significant associations between an individual ERS and AEB reported in previous research might stem from spurious correlations. The current cross-sectional study sought to examine simultaneous associations of four ERSs (rumination, problem-solving, distraction, and cognitive reappraisal) with two categories of ED symptoms (i.e., drive for thinness and bulimic symptoms) in early adolescents in Japan (ages 10-15, N = 5301). Participants self-reported their use of the different ERSs and the ED symptoms. We found certain ERSs were uniquely associated with levels of drive for thinness and bulimic symptoms even after controlling for body mass index, depression, and socioeconomic status. Particularly, frequent rumination in both boys and girls was associated with a severe drive for thinness and bulimic symptoms. Regarding adaptive strategies, frequent uses of problem-solving was associated with decreased bulimic symptoms only in girls, with the effect size being small. In addition, contrary to our expectation, greater use of distraction was associated with elevated AEBs, except the association with drive for thinness in boys. Although this study extended findings of previous research, prospective studies are required to clarify the causal relationship between ERSs and eating pathology.

Examining heart rate variability as an indicator of top-down inhibitory control over emotions and eating behaviors among individuals with and without binge eating

OBJECTIVE

Guilt increases prior to objective binge-eating episodes (OBE) and decreases following OBE, suggesting that OBE may function to regulate negative affective states. Rapid eating, a common feature of OBE, may be an observable indication of difficulty regulating eating. Heart rate variability (HRV), a measure of parasympathetic activity, is an indicator of top-down inhibitory control and indicates emotion regulation attempts. We aimed to test the effect of guilt on consumption rate and change in HRV among individuals with (+) and without (-) OBE.

METHOD

Participants (N = 86) underwent a mood induction (randomized to either a neutral mood or a guilt condition) and were then provided with 32 ounces (0.95 L) of Boost® meal replacement shake (960 kcal) and instructed to consume until they felt satisfied. Guilt was measured at baseline, prior to consumption, and following consumption. HRV was measured throughout.

RESULTS

Participants in the guilt condition reported higher guilt prior to consumption than individuals in the neutral mood condition, primarily driven by individuals with low HRV. Guilt decreased following consumption among individuals with low HRV in the guilt condition. The OBE+ individuals did not consume more or at an overall faster rate than OBE- individuals. Guilt prior to consumption did not lead to faster initial rates among OBE+ individuals; although, OBE+ individuals who experienced an increase in HRV from prior to during consumption demonstrated faster initial rates and greater changes in rate over time.

DISCUSSION

When experiencing negative emotions, individuals with OBE may experience increases in parasympathetic functioning while eating, reinforcing OBE as a facilitator of emotion regulation.

New Insights Into Causal Pathways Between the Pediatric Age-Related Physical Activity Decline and Loss of Control Eating: A Narrative Review and Proposed Conceptual Model

Research consistently suggests that loss of control (LOC) eating in children and adolescents is a key factor contributing to pediatric obesity and eating disorders. However, causes of pediatric LOC eating are yet unclear, and there is a lack of longitudinal research investigating the developmental processes contributing to LOC eating and related outcomes in youth. Physical activity is an understudied behavior that declines during middle childhood to adolescence and may exert an influence in the development of LOC eating via its impact on executive functioning. While physical activity levels and executive functioning have been linked to regulation of eating, no research has examined the mechanistic processes by which these domains may together impact LOC eating during childhood and adolescence. In the current narrative review, a model is proposed that suggests how physical activity and executive functioning influence LOC eating and related outcomes during childhood and adolescence. This model has the potential to influence future theoretical models of pediatric LOC eating and guide future prevention and intervention efforts.

A systematic and methodological review of attentional biases in eating disorders: Food, body, and perfectionism

OBJECTIVE

The current systematic and methodological review aimed to critically review existing literature utilizing implicit processing, or automatic approach- and/or avoidance-related attentional biases between eating disorder (ED) and nonclinical samples, which (a) highlights how psychophysiological methods advance knowledge of ED implicit bias; (b) explains how findings fit into transdiagnostic versus disorder-specific ED frameworks; and (c) suggests how research can address perfectionism-related ED biases.

METHOD

Three databases were systematically searched to identify studies: PubMed, Scopus, and PsychInfo electronic databases. Peer-reviewed studies of 18- to 39-year-olds with both clinical ED and healthy samples assessing visual attentional biases using pictorial and/or linguistic stimuli related to food, body, and/or perfectionism were included.

RESULTS

Forty-six studies were included. While behavioral results were often similar across ED diagnoses, studies incorporating psychophysiological measures often revealed disease-specific attentional biases. Specifically, women with bulimia nervosa (BN) tend to approach food and other body types, whereas women with anorexia nervosa (AN) tend to avoid food as well as overweight bodies.

CONCLUSIONS

Further integration of psychophysiological and behavioral methods may identify subtle processing variations in ED, which may guide prevention strategies and interventions, and provide important clinical implications. Few implicit bias studies include male participants, investigate binge-eating disorder, or evaluate perfectionism-relevant stimuli, despite the fact that perfectionism is implicated in models of ED.

Executive Function and Dysregulated Eating Behaviors in Pediatric Obesity

Objective

To examine the association between caregiver proxy report of executive function (EF) and dysregulated eating behavior in children with obesity.

Methods

Participants were 195 youth with obesity aged 8-17 years, and their legal guardians. Youth height, weight, demographics, depressive symptoms, eating behaviors, and EF were assessed cross-sectionally during a medical visit. Analyses of covariance, adjusted for child age, gender, race/ethnicity, standardized BMI, depressive symptoms, and family income were used to examine differences in youth EF across caregiver and youth self-report of eating behaviors.

Results

Youth EF differed significantly by caregiver report of eating behavior but not youth self-report. Post hoc analyses showed that youth with overeating or binge eating had poorer EF than youth without these eating behaviors.

Conclusions

Executive dysfunction, as reported by caregivers, in youth with obesity may be associated with dysregulated eating behaviors predictive of poor long-term psychosocial and weight outcomes. Further consideration of EF-specific targets for assessment and intervention in youth with obesity may be warranted.

Polygenic risk for schizophrenia, disordered eating behaviours and body mass index in adolescents

BACKGROUND

Recent studies suggest psychotic and eating disorders can be comorbid and could have shared genetic liability. However, this comorbidity has been overlooked in the epidemiological literature.AimsTo test whether polygenic risk scores (PRS) for schizophrenia are associated with disordered eating behaviours and body mass index (BMI) in the general population.

METHOD

Using data from the Avon Longitudinal Study of Parents and Children and random-effects logistic and linear regression models, we investigated the association between PRS for schizophrenia and self-reported disordered eating behaviours (binge eating, purging, fasting and excessive exercise) and BMI at 14, 16 and 18 years.

RESULTS

Of the 6920 children with available genetic data, 4473 (64.6%) and 5069 (73.3%) had at least one disordered eating and one BMI outcome measurement, respectively. An s.d. increase in PRS was associated with greater odds of having binge eating behaviours (odds ratio, 1.36; 95% CI 1.16-1.60) and lower BMI (coefficient, -0.03; 95% CI, -0.06 to -0.01).

CONCLUSIONS

Our findings suggest the presence of shared genetic risk between schizophrenia and binge eating behaviours. Intermediate phenotypes such as impaired social cognition and irritability, previously shown to be positively correlated in this sample with schizophrenia PRS, could represent risk factors for both phenotypes. Shared genetic liability between binge eating and schizophrenia could also explain higher rates of metabolic syndrome in individuals with schizophrenia, as binge eating could be a mediator of this association in drug-naïve individuals. The finding of an association between greater PRS and lower BMI, although consistent with existing epidemiological and genetic literature, requires further investigation.Declaration of interestNone.

Are the Motives for Food Choices Different in Orthorexia Nervosa and Healthy Orthorexia?

Recent research points to the bidimensional nature of orthorexia, with one dimension related to interest in healthy eating (healthy orthorexia) and another dimension related to a pathological preoccupation with eating healthily (orthorexia nervosa). Research was needed to provide further support for this differentiation. We examined the food-choice motives related to both aspects of orthorexia. Participants were 460 students from a Spanish university who completed the Teruel Orthorexia Scale and the Food Choice Questionnaire. By means of structural equation modeling, we analyzed the relationship between orthorexia, food-choice motives, gender, body mass index, and age. The motives predicting food choices in orthorexia nervosa and healthy orthorexia were quite different. In the case of orthorexia nervosa, the main motive was weight control, with sensorial appeal and affect regulation also showing significant associations. For healthy orthorexia, the main motive was health content, with sensorial appeal and price also showing significant associations. This supports the hypothesis that orthorexia nervosa is associated with maladaptive eating behavior motived more by weight control than by health concerns.

Reciprocal Prospective Relationships Between Loneliness and Weight Status in Late Childhood and Early Adolescence

Adolescents who do not conform to weight ideals are vulnerable to disapproval and victimization from peers in school. But, missing from the literature is a prospective examination of weight status and feelings of loneliness that might come from those experiences. Using data from the Québec Longitudinal Study of Child Development, we filled that gap by examining the prospective associations between loneliness and weight status when the sample was aged 10-13 years. At ages 10, 12, and 13 years, 1042 youth (572 females; 92% from French speaking homes) reported on their loneliness and were weighed and measured. Family income sufficiency was included in our analyses given its relationship with weight status, but also its possible link with loneliness during early adolescence. The findings showed that (1) weight status and loneliness were not associated concurrently; (2) weight status predicted increases in loneliness from ages 12 to 13 years; and (3) loneliness predicted increases in weight from ages 12 to 13 years among female adolescents, but weight loss among male adolescents. The fact that loneliness was involved in weight gain for females suggests that interventions focused on reducing loneliness and increasing connection with peers during early adolescence could help in reducing obesity.

Examining Two Prevailing Models of Loss of Control Eating Among Community-Based Girls

OBJECTIVE

Cognitive-behavioral and interpersonal models of loss of control (LOC) eating have been underexplored in adolescents.

METHODS

By using data from community-based adolescent girls assessed annually over 4 years, the cognitive-behavioral (n = 416) and interpersonal (n = 418) models were examined by using a regression-based bootstrapping approach.

RESULTS

Body dissatisfaction at 14 years prospectively predicted LOC eating at 18 years, both directly (direct effect = -0.039; SE = 0.017; P = 0.02) and indirectly via dieting (indirect effect = -0.010; 95% CI: -0.022 to -0.003). Interpersonal functioning at 14 years was negatively associated with negative emotionality at 17 years, which, in turn, was prospectively associated with LOC eating at 18 years (indirect effect = 0.001; 95% CI: -0.001 to -0.0003); however, the direct association between age 14 interpersonal functioning and age 18 LOC eating was not significant (direct effect = -0.001; SE = 0.001; P = 0.47).

CONCLUSIONS

These findings support the cognitive-behavioral model, and partially support the interpersonal model, with the latter findings implying that over time, negative emotionality may promote LOC eating independent of the effects of prior social functioning. Prevention and early intervention efforts for LOC eating may benefit from integrating these theoretical frameworks.

Emotion regulation strategies moderate the relationship of fatigue with depersonalization and derealization symptoms

BACKGROUND

The aim of the present study was to investigate the relationships of common emotion regulation strategies (suppression and reappraisal) to self-reported fatigue and depersonalization/derealization symptoms. Specifically, we tested the moderating effect of suppression and reappraisal on the link of fatigue with depersonalization and derealization symptoms. Opposite effects were expected for both emotion regulation strategies assuming that cognitive reappraisal has an adaptive buffering effect, while suppression intensifies the association of fatigue and depersonalization/derealization experiences.

METHODS

In a representative study (N = 2524) we assessed emotion regulation strategies, fatigue, depersonalization/derealization, distress, and demographic variables via questionnaires. 55.5% of the participants were female, mean age was 49.4 (SD = 18.2) years with age groups represented in comparable proportions.

RESULTS

In line with the assumptions, moderated regression analyses revealed an interaction effect of emotion regulation strategies and fatigue. Simple slope analyses indicated a buffering effect of cognitive reappraisal on the positive relation of fatigue with depersonalization and derealization symptoms. In contrast, suppression fosters the positive correlation of fatigue and depersonalization and derealization experiences.

LIMITATIONS

Our study is limited to these two habitual emotion regulation strategies employing a cross sectional design.

CONCLUSION

Our findings provide comprehensive empirical data investigating depersonalization/derealization symptoms from the perspective of emotion regulation research. Cognitive reappraisal might help people suffering from fatigue to prevent depersonalization and derealization tendencies.

Risk profiles of personality traits for suicidality among mood disorder patients and community controls

OBJECTIVE

To examine the associations between personality traits and suicidal ideation (SI) and attempt (SA) in mood disorder patients and community controls.

METHOD

We recruited 365 bipolar, 296 major depressive disorder patients, and 315 community controls to assess their lifetime suicidality. Participants filled out self-reported personality questionnaires to collect data of personality traits, including novelty seeking (NS), harm avoidance (HA), extraversion (E), and neuroticism (N). We used logistic regression models adjusted for diagnoses to analyze combinational effects of personality traits on the risk of suicide. Additionally, radar charts display personality profiles for suicidal behaviours by groups.

RESULTS

All personality traits were associated with the risk of suicidality with various effect size, except for E that showed protective effect. High N or HA had prominent and independent risk effects on SI and SA. Combinations of high N and low E, or high HA and NS were the risk personality profiles for suicidality. Higher N scores further distinguished SA from SI in mood disorder patients.

CONCLUSION

Introvert personality traits showed independent risk effects on suicidality regardless of diagnosis status. Among high-risk individuals with suicidal thoughts, higher neuroticism tendency is further associated with increased risk of suicide attempt.

Avoidant coping moderates the relationship between stress and depressive emotional eating in adolescents

BACKGROUND

Studies with adults support an association between emotional eating and avoidant and emotion-focused coping styles. While an avoidant coping style has been identified as a risk-factor for eating disorders in adolescents, no studies to date have specifically examined the relationship between coping styles and emotional eating in this population. The purpose of the present study was to assess whether coping styles moderate the relationship between perceived stress and emotional eating in adolescents.

METHOD

Two hundred and seventy-seven middle school students (mean age = 13.26 years; SD = 0.49) completed the Emotional Eating Scale for Children and Adolescents, the Perceived Stress Scale, the Children's Coping Strategies Checklist, and a brief demographic survey. Four separate multiple linear regression analyses were conducted to determine the interactive effects of perceived stress and coping styles on emotional eating.

RESULTS

The interaction between perceived stress and an avoidant coping style accounted for a significant amount of variance in the Emotional Eating Depression subscale score (EES-C-DEP); at higher levels of perceived stress, an avoidant coping style increased an adolescent's propensity for depressive emotional eating.

CONCLUSIONS

The present findings provide preliminary support for targeting an avoidant coping style in preventative interventions, particularly for youth that have the propensity to overeat in response to feelings of depression.

Development and preliminary effectiveness of an innovative treatment for binge eating in racially diverse adolescent girls

INTRODUCTION

Binge and loss of control (LOC) eating are significant concerns among many adolescents and are associated with poor physical, social, and psychological functioning. Black girls appear to be particularly vulnerable to binge and LOC eating. Yet, empirically validated, culturally sensitive treatments for these disordered eating behaviors are not well established. This investigation examined satisfaction, feasibility, and preliminary outcomes of a binge eating intervention for ethnically diverse adolescent girls.

METHODS

Participants were 45 girls (age 13-17years; 44.4% white, 42.2% black) randomized into a dialectical behavior therapy (DBT)-based intervention (Linking Individuals Being Emotionally Real, LIBER8) or a weight management group (2BFit). Following each meeting, participants completed satisfaction measures, and therapists assessed intervention feasibility. Participants also completed assessments of eating behavior and related psychological constructs at baseline, immediately following the intervention, and at 3-month follow-up.

RESULTS

Descriptive statistics indicated that LIBER8 was feasible, and participants were highly satisfied with this intervention. Significant reductions in eating disorder cognitions, dietary restraint, and eating in response to negative affect were observed for participants in both groups, with no differences between LIBER8 and 2BFit.

DISCUSSION

The acceptability and feasibility of LIBER8 and associated reductions in emotional eating show promise in ameliorating binge eating and provide insight into multiple options for treating this challenging eating concern.
