This study aims to determine the effect of body shaming on self-confidence in female students of the Guidance and Counseling Study Program. Body shaming is the behavior of making negative comments related to a person's physical condition that can affect psychological conditions, including self-confidence. Self-confidence is one of the important aspects in student's psychological development because it affects the individual's ability to assess and accept themselves positively. This study uses a quantitative approach with a type of causal associative research. The sample in this study amounted to 81 female students who were selected using the purposive sampling technique. Data was collected using a psychological scale in the form of a questionnaire. The data obtained was then analyzed using a simple linear regression technique. The results of the analysis showed a regression equation Y = 48.060 + (−0.110) X with a significance value of 0.000 < 0.05. These results show that body shaming has a negative and significant effect on self-confidence. A determination coefficient value (R Square) of 0.541 indicates that body shaming contributes 54.1% to self-confidence, while the remaining 45.9% is influenced by other factors outside of this study. Based on the results of the study, it was found that body shaming has an effect on students' self-confidence. The higher the body shaming experience that students receive, the lower the level of confidencethey have.
