We examined whether thinspo and fitspo exposure predicted women's body dissatisfaction (BD), happiness, and disordered eating (DE) urges (binge-eating/purging, restrictive eating, and exercise) in daily life. A further aim was to assess whether these effects were stronger for thinspo versus fitspo exposure and whether upward appearance comparisons mediated the effect of thinspo-fitspo exposure on BD, happiness, and DE urges. Participants (N = 380 women) completed baseline measures and a 7-day ecological momentary assessment (EMA) investigating state-based experiences of thinspo-fitspo exposure, appearance comparisons, BD, happiness, and DE urges. Multilevel analyses revealed that thinspo-fitspo exposure was associated with greater BD and DE urges (but unrelated to happiness) at the same EMA time point. However, there was no association between thinspo-fitspo exposure and BD, happiness, and DE urges at the next EMA time-point. Thinspo relative to fitspo exposure was associated with greater BD (but unrelated to happiness and DE urges) at the same EMA time-point. The proposed mediation models were not supported in time-lagged analyses; such that upward appearance comparisons did not mediate the effects of thinspo-fitspo exposure on BD, happiness, and DE urges. Current findings provide novel micro-longitudinal data on the potentially direct detrimental effects of thinspo-fitspo exposure on women's daily lives.
