This document summarizes a research study that investigated how receiving positive or negative comments about one's appearance prior to taking a selfie affects self-esteem. 300 participants were randomly assigned to receive no comment, a positive comment, or a negative comment from the experimenter before taking a selfie. Self-esteem was measured before and after via a questionnaire. Results showed those who received a negative comment displayed the largest decrease in self-esteem, followed by no comment, while the positive comment group increased in self-esteem. This supported the hypothesis that negative external perceptions lower self-esteem the most when taking and posting selfies.
