Purpose: This study investigated whether college-aged women could be trained to estimate the caloric content of unhealthy foods more accurately via exposure to caloric-content education, trial-by-trial feedback, and their combination.

Student Bodies includes an online, guided discussion group; however, the clinical utility of this component is unclear. This study investigated whether the guided discussion group improves program efficacy in reducing weight/shape concerns in women at high risk for an eating disorder.

We investigated eating- and weight-related correlates of self-evaluation influences (SEIs) and examined the extent to which such SEIs can be both over- and undervalued and the extent to which measurement strategy affects SEIs. A female undergraduate sample (n = 549) completed 3 measures of SEI importance and questionnaires assessing disordered eating (DE), body mass index (BMI), and depression. SEI measures included Likert scale, rank ordering, and pairwise forced choice; a subset (n = 62) also completed the Shape- and Weight-Based Self-Esteem Scale (SAWBS).
