In the conducted study, the aim was to examine the effect of disclaimers about the digital alteration of photos on negative mood and body dissatisfaction among young women. A theoretical review mainly found that disclaimers are not effective in mitigating the negative effects of exposure to idealized images of women. However, more recent research indicates that disclaimers do not have the same effects on all women, and individual differences are increasingly being included in studies. Therefore, this study also examined the moderating effects of the tendency for social comparison on social media and the tendency to manipulate photos. The research was conducted in the laboratory of the Faculty of Humanities and Social Sciences in Rijeka on a sample of 105 young women , with an average age of 22.08 years (SD = 2.53). The participants were randomly assigned to three conditions: viewing idealized images of women without a disclaimer, with a disclaimer, and viewing nature photos as a control condition. Participants in all three conditions assessed their current negative mood and body dissatisfaction before and after exposure to the experimental stimuli, while participants exposed to idealized images of women additionally assessed their tendency for social comparison and photo manipulation. The results indicate that participants in the condition without a disclaimer experienced an increase in body dissatisfaction, while there were no significant changes in the other two conditions. A significant predictor and moderator effect of the tendency to manipulate photos was also found. Specifically, participants who were more prone to photo manipulation experienced significantly lower levels of negative mood when exposed to photos with a disclaimer about digital alteration compared to participants prone to manipulation in the condition without a disclaimer. The obtained results suggest that disclaimers about digital alteration can be useful in reducing the negative effects of idealized images of women on negative mood and body dissatisfaction, considering individual differences among women.
