Using an online program 136 women were randomly assigned to view different simulated Instagram posts (16 total for each group) featuring women's bodies and specific messages about the bodies. Participants viewed various combinations of large bodies/thin bodies and positive/negative messages. ANCOVAS and T tests were performed, and it was found that the large positive group increased in mood as compared with the large negative and thin negative groups. Findings inform that the interventions were not successful in altering body image, and only message valence had an effect on participant mood. Implications, limitations and future directions are explored.
