Background : Body perception disorders, such as Body Dysmorphic Disorder (BDD), are psychological conditions often rooted in negative body image and commonly emerge during adolescence. Left untreated, BDD can lead to serious consequences, including social withdrawal, self- harm, and even suicide. Understanding the link between body image and BDD is crucial for developing effective preventive interventions. Objective : This study aims to determine the relationship between body image and body dysmorphic disorder in adolescents at SMK Negeri 2 Godean . Methods : The design was a quantitative correlational with a cross-sectional. The sample was 75 grade eleven students from three majors selected through proportionate stratified random sampling. Inclusion criteria aged 15-18 years and still actively enroled, and exclusion criteria had medically diagnosed mental disorders, routine medication, and physical disabilities that made it difficult to assess body image. Data were collected using valid and reliable body image and body dysmorphic disorder questionnaires. Chi-Square test was used for data analysis. Result : Most respondents had a positive body image as many as 52 respondents(69.3%) and negative as many as 23 respondents(30.7%). For body dysmorphic disorder, 32 respondents (42.7%) were in the moderate category, 27 respondents (36%) in the severe category, and 16 respondents (21.3%) in the mild category. Chi-Square test results showed a p value =0.333 (p> 0.05), which means there is no significant relationship between body image and BDD in students of SMK 2 Godean. Conclusion : There is no statistically significant relationship between body image and body dysmorphic disorder, with a negative relationship direction. The limitation of this study was that there are lack control over two factors, self-efficacy or self-confidence and the social support system originating from teachers, family, and peers. Therefore, future studies are expected to control other variables that may influence body dysmorphic disorder, including self-efficacy, social support, and the influence of social media on adolescents’ perceptions.
