The behavioral and affective profile of inpatient adolescent girls with restrictive anorexia nervosaAbstractBackgroundA better understanding of the individual difficulties reported by adolescents presenting with anorexia nervosa seems like an interesting avenue to refine our understanding of their psychological functioning. ObjectiveThis study aimed to: (1) describe the behavioral and affective profile of difficulties of inpatient adolescent girls presenting a restricting type of anorexia (ANR); and (2) investigate the presence of a relationship between behavioral and affective problems and severity of the disorder. MethodsThe sample consisted of 52 inpatient adolescent girls presenting an ANR. The youth self report assessed the behavioral and emotional profile of difficulties of participants while the Eating Disorder Risk Composite of the Eating Disorder Inventory measured the symptomatology of the disorder. A ratio between body mass index at admission and at the end of the treatment served as an indicator of weight gain. ResultsThe sample presented an internalized profile of problems. Individual differences were found and three profiles of difficulties were present in the sample: normative, pure internalizing and mixed (clinical on the internalizing and externalizing clusters). ConclusionThis study provides information on the heterogeneity of this specific population otherwise quite similar and demonstrates how severity of the disorder can be associated with a wide range of other behavioral and affective difficulties.

Selflessness as a predictor of remission from an eating disorder: 1–4 year outcomes from an adolescent day-care unitAbstractObjectiveTo assess the potential role of selflessness in predicting remission from an eating disorder (ED) following discharge from an adolescent day-care unit. MethodParticipants were 95 female patients (aged 13–19 years) with an ED diagnosis across the spectrum admitted to an adolescent day-care unit for EDs between 2008 and 2012. Forty-one of these participants completed the follow-up assessment, between 12 and 46 months following discharge. No significant differences were found in Time 1 variables between patients who participated in Time 2 and those who did not. At both time points, ED and psychiatric comorbidity diagnoses were made using standard structured interviews. Patients were also administered the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), The Eating Attitude Test (EAT-26), The Eating Disorder Inventory (EDI-2) and the Selflessness Scale (SS)*. ResultsOnly baseline Selflessness Scale was significant in predicting the continuous variable of ED symptomatology level in follow-up. When dividing EDI total score into its subscales at baseline, one of those, maturity fears, was found, together with the SS, significant in the prediction. In predicting remission (this time as a dichotomized variable) in follow-up, only the SS, maturity fears, EDI total, and EAT-26, at baseline, predicted remission at follow-up, but the strength of selflessness was the greatest. ConclusionsPsychological features are not the main target of the important search for predictors of remission from ED. The findings of the present study add the psychological feature of selflessness to this search. Psychotherapy can be enriched by identifying psychological features such as selflessness as one of its foci. The present findings might also renew interest in maturity fears as an additional focus in psychotherapy. Level of evidenceLevel III, cohort study. |
The association between Food and Alcohol Disturbance (FAD), race, and ethnic identity belongingAbstractPurposeA growing body of literature has established that food and alcohol disturbance (FAD: decreasing one's caloric intake in preparation for alcohol consumption) is a specific health risk that endangers health and wellbeing. Recent research on trends in FAD has revealed ethno-racial disparities. A sociological analysis is helpful to center race and examine the role of ethnic identity in reproducing health disparities. The current study is guided by theories of socialization into ideal body types by race. MethodsStudy uses data from a cross-sectional survey conducted among college students. The sample includes White and Black American college students, ages 18–25, and uses ordinal logistic regression to test for the impact of race and ethnic identity on engagement in FAD using the Compensatory Eating and Behaviors in Response to Alcohol Consumption Scale (CEBRACS). ResultsFAD prevalence was lower among Black Americans than among White Americans in the sample. Results from ordered logistic regression models indicate that stronger ethnic ties reduce likelihood of FAD among Black Americans but have the opposite effect among White Americans. This modification effect provides evidence that ethnic identity belonging protects against FAD for Black Americans but acts as a risk factor for FAD among White Americans. ConclusionsFindings shed light on the documented racial disparities in FAD and weight control behavior more broadly. Ethnic identity modifies the relationship between race and FAD in our sample.

Characteristics of patients in an eating disorder sample who dropped out: 2-year follow-upAbstractObjectiveThis manuscript explores the characteristics of individuals diagnosed with an eating disorder who dropped out of treatment, compared with those who completed it. MethodThe participants were 196 patients diagnosed with eating disorders (according to DSM-IV-TR criteria) who consecutively began treatment for the first time in an eating disorders unit. They were assessed at baseline with a set of questionnaires evaluating eating habits, temperament, and general psychopathology. During the follow-up period, patients who dropped out were re-assessed via a telephone interview. ResultsIn the course of a 2-year follow-up, a total of 80 (40.8%) patients were labeled as dropouts, and 116 (59.2%) remaining subjects were considered completers. High TCI scores in the character dimensions of Disorderliness (NS4) (p < .01) and total Novelty Seeking (NST), along with low scores in Dependency (RD4), were significantly associated with dropout in the course of 2 years. Once the results were submitted to logistic regression analysis, dropout only remained associated with high scores in Disorderliness (NS4) and, inversely, with an initial Anorexia Nervosa (AN) diagnosis (p < .05). Reasons for dropout stated by the patients included logistic difficulties, subjective improvement of their condition, and lack of motivation. DiscussionClinicians should handle the first therapeutic intervention with particular care in order to enhance their understanding of clients and their ability to rapidly identify those who are at risk of dropping out of treatment.

Food craving predicts the consumption of highly palatable food but not bland foodAbstractThe impact of obesity on physical and psychological health is well recognized in the literature with, among others, evidence of alterations in cognition. Indeed, obese populations are characterized by lower executive functions as well as an enhanced food craving. However, the relationship between executive functions and food craving remains unexplored. Moreover, these two variables have also been shown to predict food intake, but studies in the context of obesity are lacking. Thus, this study had two objectives: (1) determining if executive functions and food craving are linked, and (2) examining the predictors of highly palatable food intake and bland food intake. First, it was hypothesized that executive functions would be negatively associated with food craving. Second, it was expected that food craving would predict positively highly palatable food intake but not bland food intake. Third, it was predicted that executive functions would predict negatively highly palatable food intake and positively bland food intake. 48 participants (34 females) with BMIs ranging from 17.9 to 46.4 took part in two experimental sessions. First, executive functions were assessed using the delayed discounting task (impulsivity towards food and money) and the color–word interference test (CWIT; inhibition/flexibility). Second, a cue-induced food craving protocol, with images as well as real food, was administered followed by an ad libitum food intake protocol including both highly palatable and bland food. The inhibition/flexibility condition of the CWIT was significantly and negatively correlated with food craving following induction. Highly palatable food intake was significantly predicted by food craving following induction, but bland food intake was not. This study reveals an association between lower inhibition/flexibility and susceptibility to food craving induction that is of great importance in obesogenic environments. Moreover, this study confirmed the link between food craving and food intake, and showed for the first time a specific contribution of food craving to highly palatable food intake but not to bland food intake, highlighting its potential influence in obesity. This work leads to future research questions regarding the possible benefits of cognitive remediation interventions, as well as interventions aiming at reducing food craving, in weight loss programs.

Gender differences in relations between alcohol-related compensatory behavior and eating pathologyAbstractPurposeConcerns about caloric intake associated with alcohol use (e.g., fear of weight gain) are positively associated with compensatory eating behaviors (e.g., caloric restriction, self-induced vomiting), a phenomenon that has been identified across gender. Specific motivations for compensatory behaviors differ; some relate to eating disorder (ED) pathology (e.g., shape and weight concerns), and others to alcohol (e.g., enhancing effects). Research examining motivations for alcohol-related compensatory behaviors in men is limited to date. The current study sought to assess how specific types of alcohol-related compensatory behaviors and their association with ED pathology present differently by gender. MethodsUndergraduates (N = 530, 48% female) completed the Compensatory Eating Behaviors in Response to Alcohol Consumption Scale (CEBRACS), Eating Disorders Diagnostic Scale (EDDS), and reported height, weight, and frequency and quantity of alcohol consumption. Data were examined using linear regression, and relations between CEBRACS behaviors and eating pathology were compared across gender. ResultsFactors that were positively associated with EDDS scores for both men and women included alcohol-related dietary restraint, and exercise. For women, but not men, alcohol-related bulimic behavior also contributed to elevations in EDDS scores. ConclusionsFindings indicate that specific types of alcohol-related compensatory eating behaviors (i.e., dietary restraint and exercise) are positively related to ED pathology for both male and female participants. In contrast, bulimic behaviors' association with ED pathology is gender specific. Understanding gender differences in alcohol-related compensatory behaviors and ED risk may inform gender-specific intervention targets. Level of evidenceCross-sectional descriptive study, Level V. |
Testing virtual reality-based cue-exposure software: Which cue-elicited responses best discriminate between patients with eating disorders and healthy controls?AbstractPurposeVirtual reality (VR) technologies have been proposed as a new tool able to improve on in vivo exposure in patients with eating disorders. This study assessed the validity of a VR-based software for cue exposure therapy (CET) in people with bulimia nervosa (BN) and binge eating disorder (BED). MethodsFifty eight outpatients (33 BN and 25 BED) and 135 healthy participants were exposed to 10 craved virtual foods and a neutral cue in four experimental virtual environments (kitchen, dining room, bedroom, and cafeteria). After exposure to each VR scenario, food craving and anxiety were assessed. The frequency/severity of episodes of uncontrollable overeating was also assessed and body mass index was measured prior to the exposure. ResultsIn both groups, craving and anxiety responses when exposed to the food-related virtual environments were significantly higher than in the neutral-cue virtual environment. However, craving and anxiety levels were higher in the clinical group. Furthermore, cue-elicited anxiety was better at discriminating between clinical and healthy groups than cue-elicited craving. ConclusionsThis study provides evidence of the ability of food-related VR environments to provoke food craving and anxiety responses in BN and BED patients and highlights the need to consider both responses during treatment. The results support the use of VR-CET in the treatment of eating disorder patients characterized by binge-eating and people with high bulimic symptoms. |
Eating disorder symptoms and the 2 × 2 model of perfectionism: mixed perfectionism is the most maladaptive combinationAbstractPurposeThe 2 × 2 model of perfectionism (Gaudreau and Thompson in Personal Individ Diff 48:532–537, 2010) represents an important addition to the perfectionism literature, but so far has not been studied in relation with disordered eating. MethodUsing the 2 × 2 model as analytic framework, this study examined responses from a convenience sample of 716 participants aged 19–68 years (71% female) investigating how self-oriented perfectionism (SOP) and socially prescribed perfectionism (SPP) predicted individual differences in eating disorder symptoms, additionally controlling for body mass index, gender, and age. ResultsResults showed a significant SOP × SPP interaction indicating that the combination of high SOP and high SPP—called "mixed perfectionism"—was associated with the highest levels of eating disorder symptoms. ConclusionsThe findings demonstrate the utility of the 2 × 2 model of perfectionism as an analytic framework for examining perfectionism and disordered eating. Moreover, they suggest that mixed perfectionism is the most maladaptive form of perfectionism when it comes to disordered eating, such that having high levels of SPP combined with high levels of SOP represents the most maladaptive combination of perfectionism in terms of risk of eating disorder.

Baseline motives for eating palatable food: racial differences and preliminary utility in predicting weight lossAbstractPurposeBehavioral predictors of weight-loss program (WLP) outcomes are needed and important because they can be modified. Eating calorie-dense palatable foods (PFs) outside of hunger contributes to obesity. This study assessed if habitual motives to consume PFs could predict weight-loss outcomes. MethodsN = 171 Black and N = 141 White adults in a reduced-calorie program completed the Palatable Eating Motives Scale (PEMS). Body weight and body mass index (BMI) lost after 3 and 6 months were analyzed controlling for initial BMI and demographics. Greater PEMS motive scores meant more frequent habitual intake of PFs for that motive. ResultsWhites vs. Blacks had higher scores on most of the PEMS motives: Social, Coping, and Reward Enhancement. In Whites at 3 months, greater Reward Enhancement scores and initial BMI predicted more BMI loss (p < 0.05). At 6 months, greater Reward Enhancement and lower Conformity scores predicted more weight (p < 0.05) and BMI loss (Conformity: p < 0.05; Reward Enhancement: p = 0.05). PEMS motives did not predict outcomes for Blacks. ConclusionThe results provide preliminary evidence for the PEMS to predict WLP outcomes. White patients who eat PFs primarily for their rewarding properties and less to conform should fare better in Lifestyle programs while group or family-based interventions may be more efficacious when conformity is the main motive. Lower motive scores among Blacks suggest that eating PFs outside of hunger may go unrecognized or underreported and warrants further investigation. The findings highlight the motive-based heterogeneity of obesity and how it may be used to predict outcomes and customize interventions to improve WLP outcomes.
