Objectives: To identify factors associated with cancer screening intention using the Theory of Planned Behavior (TPB).
Methods: Among 55,920 eligible persons for National Cancer Screening Program (NCSP) in J city, 1,100 individuals were
contacted. Of these, 797 were interviewed using a structured questionnaire. Thirty-six responses were excluded due to
incomplete data. The remaining 761 completed questionnaires were analyzed to find factors associated with cancer screening
intention.
cancer screening intention in multiple linear regression analysis. External factors such as socio-demographic status, health and
health behavior variables explained 8.9% of screening intention. Among them, household monthly income, past cancer
screening experience, exercise and daily eating habit were significantly associated with screening intention.
Conclusions: Cancer screening intention may be influenced by focusing attitude, subjective norm in TPB model and other
external factors. However, further studies are warranted to identify factors influencing cancer screening intention and behavior.
