Body image is a significant issue faced by many female university students, largely due to the influence of beauty standards portrayed on social media. Body image can be positive or negative and is closely linked to an individual's ability to accept themselves. This study aimed to determine the influence of self-acceptance on body image among female students at the Faculty of Psychology, Universitas Muhammadiyah Jember. A quantitative approach with a correlational design was employed. The sample consisted of 158 female students from the Faculty of Psychology, Universitas Muhammadiyah Jember (Class of 2020–2025), selected using random sampling. Data were collected using the Self-Acceptance Scale (18 items; α = 0.659) and the Body Image Scale (19 items; α = 0.671) and subsequently analyzed using simple linear regression with Jamovi software (version 2.7.38). The results indicate a positive and significant influence of self-acceptance on body image (R = 0.657; p < 0.05). The self-acceptance variable contributed 43.1% to the variation in body image among the female students, while the remaining 56.9% was explained by factors outside the scope of this study. The regression coefficient was 0.860, indicating that for every unit increase in self-acceptance, body image increased by 0.860 units. Thus, the research hypothesis stating that self-acceptance influences body image among female students at the Faculty of Psychology, Universitas Muhammadiyah Jember, is accepted.
