Abstract
3D body scanning technology is becoming increasingly popular in the apparel and health industries due to its accessibility, affordability, and precision. 3D images offer biometrically accurate images for estimating body shape and size, which may align mental constructs of the body with an objective body assessment, which would be helpful in illustrating the effects of treatments or interventions for lifestyle‐related diseases and body image disorders by demonstrating physical changes to the body. This five‐phase one‐group exploratory study examined affective responses to obtaining a full‐body 3D scan. In a sample of 45, we used summative content analysis and inductive content analysis to examine two open‐ended questions about the body scan experience, body visualization, and affect. The study found that participants generally reacted positively to the scanning experience, but some reported negative affective responses, such as self‐consciousness. Some participants experienced stress and decreased body satisfaction due to the detailed and realistic nature of the scans highlighting perceived imperfections. The study found few gender differences in responses, with men showing slightly more positive reactions. This aligns with patterns of body surveillance and psychological distress being more pervasive in women. Both men and women are affected by cultural pressures related to body image, leading to self‐objectification and psychological distress, which highlights the need for ethical use of the technology to minimize potential harm.
