The purpose of this study was to predict the factors which are related to the intention and behaviour for breast self-examination (BSE) of middle aged women using the theory of planned behavior (TPB). A survey using a structured questionnaire was conducted wih 217 middle aged women. BSE behaviour was assessed at 1-month follow-up. The overall fit of the structural model to the date was acceptable(${\chi}^2$=1246.6(p<.001), ${\chi}^2$/df=2.72, CFI=.831, TLI=.817, RMSEA=.089). The BSE behavior rate within one month was 56.2%. The TPB explained 43.9% of the variance in BSE intentions and 10.9% of the variance in BSE behavior. The subjective norm(${\beta}$=.364, p<.001) and the perceived behavioral control(${\beta}$=.553, p<.001) both positively influenced the behavioral intention, and the behavioral intention(${\beta}$=.768, p<.01) positively influenced the behavior. This study shows the model's applicability in explaining BSE behavior of middle aged women, and suggests that health intervention programs should focus on strengthening the intention for the promotion of BSE behavior.
