Reasoned action theory is adapted to study the influence of body satisfaction and subjective norm (the role of others) on behavioral intention and behavior to change the body. Data are collected from 301 female undergraduate students. Causal model analyses are conducted by a maximum‐likelihood estimation procedure using LISREL 8.72. Overall, fit of the model is highly adequate. Participants who have high body satisfaction scores are less likely to want to change their bodies. Participants who think that significant others (parents, siblings, and friends) want them to change their bodies and who are inclined to comply with those significant others are more likely to want to change their bodies. Participants with greater intention to change their bodies are more likely to try to change them. The results support reasoned action theory.
