Obsessive attitudes toward diet and exercise could be associated with binging on food and then engaging in vigorous exercise as a strategy to rid the body of calories. KEY WORDS: Eating attitudes, model testing, external validity, exercise and health.Īlthough exercise is associated with numerous health related benefits such as weight management, recent research suggests that it also can be linked with dysfunctional attitudes and behaviors (Szabo, 2000). Collectively, findings suggest that a 21-item four-factor model shows promising validity coefficients among exercise participants, and that future research is needed to investigate eating attitudes among samples of exercisers. Further, dieting was inversely related with self-determination toward exercising. Correlation results indicated that depressed mood scores positively correlated with bulimia and dieting scores. Stage two explored relationships between EAT scores, mood, self-esteem, and motivational indices toward exercise in terms of self-determination, enjoyment and competence.
CFA results for the four-factor model showed acceptable fit indices (RCFI = 0.98, RMSEA = 0.06). CFA results indicated that the single-factor model (RCFI = 0.76, RMSEA = 0.10) and three-factor model (RCFI = 0.82, RMSEA = 0.08) showed poor fit. After these 5-items were discarded, the three models were re-analyzed. Results indicated five-items showed poor factor loadings. There was marginal fit for the 4-factor model (RCFI = 0.91, RMSEA = 0.06). CFA of the single-factor model (RCFI = 0.66, RMSEA = 0.10), the three-factor-model (RCFI = 0.74 RMSEA = 0.09) showed poor model fit. Confirmatory factor analysis (CFA) was used to test the single-factor, a three-factor model, and a four-factor model, which distinguished bulimia from food pre-occupation. In stage one, 598 regular exercisers completed the EAT. The second purpose was to investigate relationships between eating attitudes scores and selected psychological constructs. The primary purpose of the study was to examine the factorial validity of the EAT among a sample of exercisers.
The original factor analysis showed three interrelated factors: Dieting behavior (13-items), oral control (7-items), and bulimia nervosa-food preoccupation (6-items). The Eating Attitude Test (EAT) is a 26-item measure that yields a single index of disordered eating attitudes. To date, no published research has looked at the factorial validity of an existing eating attitude inventory for use with exercisers.
Theory testing and construct measurement are inextricably linked.
