Disentangling relations between the desirability of the thin-ideal, body checking, and worry on college women's weight-loss dieting: A self-regulation perspective

The study used self-regulation theory to elucidate the relationships between the desirability of the thin-ideal goal, dispositional worry, body checking and weight-loss dieting (WLD) in college women. We hypothesized that body checking would mediate the relationship between the desirability of the thin-ideal goal and WLD: the desire to be thin would be associated with more WLD through more frequent body checking. We also hypothesized that dispositional worry would moderate this mediation pathway, such that the mediation pathway would be stronger for those higher in worry. Finally, all effects were expected to occur when controlling for self-reported body size. A paper and pencil survey was conducted on a convenience sample of 237 college women who completed measures of: thin-ideal desirability, dispositional worry, body checking, WLD, as well as providing height and weight. A bootstrap analysis using PROCESS (Hayes, 2013) supported the hypothesized moderated mediation model. Findings add to current knowledge by elucidating the nature and function of body checking, and by so doing may provide insight into the prevention and treatment of disordered eating.
