Etiological models of eating disorders (EDs) describe body dissatisfaction (BD) as one of the major influences fostering dysfunctional body-related behavior and disordered eating behavior. BD is influenced by repeated exposure to thin ideals that evoke high self-ideal discrepancy and result in body-related cognitive distortions such as thought-shape fusion body (TSF-B). The aim of the study was to investigate the covariation of daily media exposure and the experience of TSF-B in a naturalistic setting. It was further analyzed whether TSF-B is associated with self-ideal discrepancy, dysfunctional body-related behavior and disordered eating behavior. Moreover, person-related predictors of TSF-B were explored. Altogether 51 healthy female students (mean age 21.06 years, SD=1.76) participated in an ecological momentary assessment study with 4 daily surveys during 10 consecutive days. Exposure with thin ideals in contrast to exposure to unspecific media contents went along with the experience of TSF-B. TSF-B was associated with higher self-ideal discrepancy, dysfunctional body-related behavior as well as more pronounced disordered eating behavior, suggesting that TSF-B is a common phenomenon in young healthy females' everyday life. A main effect of trait measures (e.g. preexisting BD) on TSF-B was observable, but no moderating effect. Thus, a specific vulnerability has not been detected.
