Obligatory exercise and coping in treatment-seeking women with poor body image.

PURPOSE: Obligatory exercise is characterized by continued exercise despite negative consequences, and intense negative affect when unable to exercise. Research suggests psychosocial differences between individuals that exercise in an obligatory manner and those that do not. It also has been speculated that obligatory exercise may serve coping and affect regulation functions, yet these factors have not been routinely examined in community women with poor body image. The purpose of the current study was to investigate psychosocial differences between obligatory and non-obligatory exercisers, and to examine the use of obligatory exercise as an avoidant coping strategy in a sample of women with poor body image. METHODS: Women (n = 70) seeking treatment for body dissatisfaction were divided into obligatory and non-obligatory exercise groups based on their scores on the Obligatory Exercise Questionnaire. Participants then completed an assessment battery about eating pathology, body image, reasons for exercise, coping strategies, and negative affect. RESULTS: Independent t test analyses indicated that obligatory exercisers had significantly greater eating disorder symptomatology, avoidant coping, and appearance- and mood-related reasons for exercise than non-obligatory exercisers. Multiple regression analyses revealed that eating disorder symptomatology and avoidant coping were significant predictors of obligatory exercise. CONCLUSIONS: There are distinct psychosocial differences between women with poor body image who exercise in an obligatory fashion and those who do not. The current study suggests that obligatory exercise may serve as an avoidant coping strategy for women with poor body image. Enhancing healthy coping strategies may be an important addition to body image improvement programs. LEVEL OF EVIDENCE: V, cross-sectional descriptive study.

Characterizing severe and enduring anorexia nervosa: An empirical approach.

Targeted approaches for the treatment of severe and enduring anorexia nervosa (SE-AN) have been recommended, but there is no consensus definition of SE-AN to inform research and clinical practice. This study aimed to take initial steps toward developing an empirically based definition of SE-AN by characterizing associations among putative indicators of severity and chronicity in eating disorders. Patients with AN (N = 355) completed interviews and questionnaires at treatment admission and discharge; height and weight were assessed to calculate body mass index (BMI). Structural equation mixture modeling was used to test whether associations among potential indicators of SE-AN (illness duration, treatment history, BMI, binge eating, purging, quality-of-life) formed distinct subgroups, a single group with one or more dimensions, or a combination of subgroups and dimensions. A three-factor (dimensional), two-profile (categorical) mixture model provided the best fit to the data. Factor 1 included eating disorder behaviors; Factor 2 comprised quality-of-life domains; Factor 3 was characterized by illness duration, number of hospitalizations, and admission BMI. Profiles differed on eating disorder behaviors and quality-of-life, but not on indicators of chronicity or BMI. Factor scores, but not profile membership, predicted outcome at discharge from treatment. Data suggest that patients with AN can be classified on the basis of eating disorder behaviors and quality-of-life, but there was no evidence for a chronic subgroup of AN. Rather, indices of chronicity varied dimensionally within each class. Given that current definitions of SE-AN rely on illness duration, these findings have implications for research and clinical practice.

Physical activity and post-treatment weight trajectory in anorexia nervosa.

OBJECTIVE: This study compared an objective measurement of physical activity (PA) in individuals with anorexia nervosa (AN) at low-weight, weight-restored, and post-treatment time points, and also compared PA in AN with that of healthy controls (HC). METHOD: Sixty-one female inpatients with AN wore a novel accelerometer (the IDEEA) which measured PA at three time points: a) low-weight, b) weight-restored, and c) one month post-hospital discharge. Twenty-four HCs wore the IDEEA at one time point. RESULTS: Inpatients with AN became more physically active than they were at low-weight at weight restoration and following treatment discharge. Post-treatment patients with AN were more physically active than HCs during the day and less active at night, which was primarily accounted for by amount of time spent on feet, including standing and walking. Greater time spent on feet during the weight-restoration time point of inpatient treatment was associated with more rapid decrease in BMI over the 12 months following treatment discharge. Fidgeting did not differ between patients and controls, did not change with weight restoration, and did not predict post-treatment weight change. DISCUSSION: Use of a novel accelerometer demonstrated greater PA in AN than in HC. PA following weight restoration in AN, particularly time spent in standing postures, may contribute to weight loss in the year following hospitalization. © 2015 Wiley Periodicals, Inc.

The reinforcing effect of exercise in anorexia nervosa: Clinical correlates and relationship to outcome.

The purpose of the current study was to examine the relative reinforcing effect of exercise compared to a non-monetary alternative reinforcer (leisure activity), and to money, before and after weight restoration in an inpatient population with anorexia nervosa (AN). Sixty-two inpatients with AN completed a progressive ratio (PR) task to earn exercise, leisure activities, or cash at low weight and after weight restoration. Measures of pathology and motivation to exercise were completed and post-treatment discharge weights were collected. Patients worked harder for exercise at low weight than after weight restoration (df = 46, t = 5.50, p < .001). PR task performance was weakly associated with a measure of commitment to exercise (low weight: r = 0.31, weight restored: r = 0.36, p < .05), but not with other clinical measures or follow-up weights. Contrary to prior suggestions, measurement of the reinforcing value of exercise among individuals with AN via a PR task does not appear valuable in assessing clinical severity or outcome. Other, simpler, self-report measures of commitment to exercise may have greater value in assessing these outcomes.

A Behaviorally-Anchored Rating System to Monitor Treatment Integrity for Community Clinicians Using the Adolescent Community Reinforcement Approach.

This study evaluated a process for training raters to reliably rate clinicians delivering the Adolescent Community Reinforcement Approach (A-CRA) in a national dissemination project. The unique A-CRA coding system uses specific behavioral anchors throughout its 73 procedure components. Five randomly-selected raters each rated "passing" and "not passing" examples of the 19 A-CRA procedures. Ninety-four percent of the final ICCs were at least 'good' (≥.60) and 66.7% were 'excellent' (≥.75), and 95% of the ratings exceeded the 60% or better agreement threshold between raters and the gold standard. Raters can be trained to provide reliable A-CRA feedback for large-scale dissemination projects.

Eating pathology, emotion regulation, and emotional overeating in obese adults with Binge Eating Disorder.

OBJECTIVE: The purpose of the current study was to examine the relationship among emotional regulation, emotional overeating, and general eating pathology in a treatment seeking sample of adults with Binge Eating Disorder (BED). METHOD: The sample was composed of 326 adults (248 women, 78 men) who were obese and met DSM-IV-TR criteria for BED. Prior to treatment, participants completed the Difficulties in Emotion Regulation Scale (DERS), Emotional Overeating Questionnaire (EOQ), Beck Depression Inventory (BDI), and Eating Disorder Examination-Questionnaire (EDE-Q) as part of a larger assessment battery. RESULTS: A series of hierarchical regression analyses indicated that difficulties with emotion regulation accounted for unique variance in both emotional overeating and general eating pathology above and beyond sex and negative affect. DISCUSSION: Emotion regulation may play a significant role in the maintenance of emotional overeating and eating pathology in obese adults with BED.

Measurement invariance of the Eating Attitudes Test-26 in Caucasian and Hispanic women.

To determine whether the EAT-26 functions similarly in Caucasian and Hispanic samples, the current study investigated the factor structure of the Eating Attitudes Test (EAT-26) in 235 undergraduate Caucasian (53.6%) and Hispanic (46.4%) women, and tested for measurement invariance across the two samples. A Confirmatory Factor Analysis (CFA) of the original 3-factor structure of the EAT resulted in a poor fit in both the Caucasian and Hispanic samples. We then performed a CFA using a previously discovered 4-factor, 16-item structure. This abbreviated measure was a good fit in both the Caucasian and Hispanic samples, and the model was invariant across all dimensions tested. The 16-item EAT is a better-fitting measure in Caucasian and Hispanic women than the commonly used EAT-26. This replicates an earlier finding and generalizes those conclusions to a Hispanic sample.
