Abstract Objectives For a subset of dieters, the pursuit of thinness may be harmful. In contrast, eating competence is associated with positive physical and mental health outcomes. This pilot intervention study evaluated changes in eating competence and disordered eating symptoms among previous dieters who participated in the How to Eat program using two delivery modes at a major midwestern university. Methods Participants were adult employees of the university who self-identified as previous dieters and voluntarily enrolled in How to Eat in either individual sessions or group classes (self-selected) over a nine-year period as part of employee health promotion offerings. How to Eat, offered weekly over 10 sessions, is grounded in the validated Eating Competence model, and measured by the ecSI 2.0™, which defines eating competence as comprised of 4 domains: 1) eating attitudes; 2) food acceptance; 3) food management/contextual skills; and 4) internal regulation of eating. A total score on the ecSI 2.0™ of at least 32 (of 48 total) indicates eating competence. Symptoms of eating disorders were evaluated with the Eating Attitudes Test-26 (EAT-26). Two-factor ANOVA was used for analyses. Results A total of 160 employees participated in How to Eat. Those participating in individual sessions were significantly younger (M = 38.3 years) and attended a greater number of sessions (M = 9.3) than those participating in group classes (M = 48.1 years and M = 5.9 sessions). Adjusting for age and number of sessions, there was a significant interaction between intervention and session type for ecSI 2.0™ total scores [F(1, 149) = 21.424, P < 0.001, ƞ2 = 0.126], all four subscale domain scores, and EAT-26 total scores [F(1, 149) = 14.035, P < 0.001, ƞ2 = 0.086]. Improvements in scores were significantly greater for participants in the individual sessions than the group classes. Body weight was not significantly influenced by the intervention. Conclusions How to Eat is associated with improvements in measures of eating competence and symptoms of disordered eating among previous dieters, and these improvements are greater for those participating in individual sessions versus group classes in a university employee wellness setting. Further research is needed to evaluate the efficacy and additional health-related outcomes of the How to Eat method among diverse populations and other settings. Funding Sources None.
