Pengaruh Peer Appearance Culture Terhadap Body Image Dissatisfaction Pada Remaja di SMKN 1 Wonorejo

Abstract

Body image dissatisfaction has become one of the most common psychological issues experienced by adolescents, particularly due to the increasing emphasis on physical appearance within peer groups. This study aimed to determine the effect of peer appearance culture on body image dissatisfaction among adolescents at SMKN 1 Wonorejo. This research employed a quantitative approach with a correlational design. The population consisted of 1,060 students from grades X and XI, while 290 respondents were selected using proportionate stratified random sampling. Data were collected using the Peer Appearance Culture Scale and the Body Image Dissatisfaction Scale, both of which had met validity and reliability requirements. Data analysis was conducted using simple linear regression. The findings revealed that peer appearance culture had a positive and significant effect on body image dissatisfaction (p = 0.000 < 0.05). The coefficient of determination (R²) was 0.891, indicating that 89.1% of the variance in body image dissatisfaction could be explained by peer appearance culture, while the remaining 10.9% was influenced by other factors outside this study. The regression equation obtained was Y = 35.554 + 0.441X, indicating that every one-unit increase in peer appearance culture was followed by a 0.441-unit increase in body image dissatisfaction. These findings suggest that peer appearance culture plays an important role in shaping adolescents' perceptions of their bodies. Therefore, schools and families should foster a supportive social environment that promotes positive body image and reduces appearance-based pressure among adolescents.
