This study delves into the global impact of body dysmorphia, concentrating on problems with visual processing in those who have body dysmorphic disorder (BDD). Using self-report questionnaires, clinical diagnosis, and cognitive bias tests on a diverse sample of 446 individuals, the study investigates how BDD impacts visual processing. The findings are expected to demonstrate the greater challenges with visual processing that individuals with BDD have when compared to those without the disease, and they also demonstrate the substantial influence that a BDD diagnosis has. Additionally, a strong primary influence of cognitive biases is demonstrated, indicating that negative attentional biases amplify issues with visual processing. It is noteworthy that there does not appear to be a significant interaction between cognitive biases and BDD diagnosis, suggesting that their combined effects on visual processing are additive rather than synergistic.
