Are Mixed-Sex and Single-Sex Groups Equally Effective Across Males and Females? A Quasi-Experimental Investigation of a Cognitive Dissonance-Based Eating Disorder Prevention Program in Mixed-Sex High School Populations

The Body Project is a cognitive dissonance-based eating disorder (ED) preventive intervention program with ample empirical support among adolescent and undergraduate female samples. Recently, community stakeholders and data suggest that preventive efforts must also target body satisfaction and increasing ED symptomatology seen in males. The current study examined the efficacy of a male-only (MO), a mixed-sex (MS), and a traditional female-only (FO) Body Project program compared to a minimal attention control (AC) in a community sample. Participants included adolescents male and female students (N = 182) aged 13-19 years across three high school sites. Participants completed self-report measures assessing body satisfaction, thin-ideal internalization, ED symptom count, psychosocial impairment secondary to weight and shape concerns, and acceptability of the Body Project 4 High Schools program at baseline and post-intervention. Hierarchical linear regressions and generalized linear models were used to estimate main effects of condition and examine whether sex moderated condition effects on outcome variables. In single-sex groups, girls showed greater improvement in body satisfaction compared to AC, while boys did not show significant differences from AC. For boys and girls, MS was associated with improved body satisfaction compared to AC, while its impact on other risk factors was largely non-significant. Effect sizes are presented as a measure of clinical significance. These results contribute to existing Body Project data and provide preliminary empirical support of the applicability of the well-established dissonance-based preventive intervention to adolescent boys

The Role of Craving in Emotional and Uncontrolled Eating

This study presents a novel application of the cognitive processing model of alcohol craving (CPMA) from the addictions field to the role of food craving in the well-established restrained eating–overeating relationship associated with binge eating disorder (BED). A community sample (N = 1058, ages 18-66) completed an online survey assessing four core domains: restrained eating, trait food craving, uncontrolled eating, and emotional eating. In accordance with the CPMA, food craving emerged as a significant indirect effect of the association between restrained eating and both uncontrolled and emotional eating. Gender did not significantly moderate any direct or indirect associations, suggesting that gender may not change the pattern of association between restrained eating and different facets of overeating. Results suggest that treatments targeting binge eating behaviors may benefit from 1) explicitly addressing the activation of food craving rather than concentrating on reducing restrained eating and 2) recognizing that food craving may be an important gender-neutral target with the potential to reduce binge and overeating behaviors. Future research should extend these preliminary findings by examining the application of the CPMA to eating behaviors while jointly investigating antecedents and contextual factors

Tailoring a Dissonance-Based Body Image Intervention for Adult Women in a Proof of Concept Trial: The Women\u27s Body Initiative

Although historically conceptualized as problems of youth, recent research indicates that women of all ages experience body dissatisfaction and eating disorder (ED) pathology. Despite this, existing body image interventions predominantly target youth. The Body Project (BP) has extensive support for reducing ED risk factors in younger women and girls. The current proof-of-concept study investigated the feasibility, acceptability, and estimates of intervention effect sizes of a modified BP for adult women, the Women’s Body Initiative (WBI). Conducted in the Southwestern United States, adult women (N = 13) aged 29–70 (M = 49.1) participated in 4, 1-h weekly sessions, completing measures at baseline, post-intervention, and 3-month follow-up. Participants rated the program as highly feasible and acceptable. Within-subjects effects sizes were medium to large for primary outcomes (body dissatisfaction, ED pathology) and secondary outcomes (psychosocial impairment, negative affect, quality of life, nutritious food consumption, and sleep) through 3-months. Results suggest preliminary feasibility and acceptability of WBI for adult women, and support proceeding with a larger trial to investigate intervention efficacy

Eating Disorder Symptomatology Among Adolescents Presenting for Bariatric Surgery Candidacy: Examining Differences by Sex and Racial Minority Status.

BACKGROUND: Research on adolescent bariatric surgery candidates is limited by insufficient inclusion of ethnic minorities and males, and lack of consideration of the full spectrum of disordered eating behaviors (i.e., restriction, compensatory behaviors [e.g., purging], overeating/binge eating behaviors). OBJECTIVES: The current study investigated differences in the full range of disordered eating behaviors across sex and ethnicity among adolescents seeking bariatric surgery. SETTING: Teaching hospital, United States. METHODS: Data were collected using retrospective chart review of 79 adolescent bariatric surgery candidates (59% female, 46.8% Hispanic, M RESULTS: Approximately 33% of study participants met self-reported criteria for an eating disorder, with 35% endorsing binge eating behaviors and 50% endorsing compensatory behaviors. Few differences in behavior frequencies were observed across sex or racial/ethnic status. CONCLUSIONS: Findings underscore the importance of assessing the full spectrum of disordered eating behaviors among adolescent bariatric surgery candidates
