Body Dissatisfaction occurs a lot in women during emerging adulthood, this happens because at this phase women are required to be successful in their careers and in relationships with the opposite sex. The high demands from the social and family environment as well as exposure to mass media make women in this phase compare themselves with others. This study aims to determine the relationship between social comparison and body dissatisfaction in early adult women. A total of 350 women in early adulthood who were taken using the convenience sampling technique participated in this study. Research data was taken using The Iowa-Netherlands Comparison Orientation Measure (INCOM) which has been adapted by the researcher through standardized adaptation procedures and the Body Dissatisfaction scale which was compiled by the researcher himself based on Rosen & Reiter (1995). Spearman's Rho correlation technique is used to analyze research data. The results show that there is a very significant relationship between social comparison and body dissatisfaction. The results of this study can be used as a reference for the importance of increasing Social Comparison in emerging adulthood women to reduce body dissatisfaction.
