Fecal Occult Blood Testing (FOBT) can reduce the incidence and the mortality of colorectal cancer. However, the use of Fecal Occult Blood Testing still remained low. To exam and understand the behavioral intention and its relevant factors of Fecal Occult Blood Testing can effectively improve the control of colorectal cancer.
Objective: This study aimed at investigating the behavioral intention of 50-74 year-old community residents to participate in Fecal Occult Blood Testing, and using the Theory of Planned Behavior (TPB) to explore relevant factors that affect their intentions.
Methods: Residents of the Chienci District in Kaohsiung City were recruited in this cross-sectional study. A structured questionnaire survey was implemented and data were collected from November 1, 2011 to February 28, 2012. 270 questionnaires were distributed and 262 returned of which 256 questionnaires were valid. A total valid response rate was 94.8%. Data was recorded and analyzed by the SPSS statistical software.
Results: 65.2% of subjects participated in this study did use the Fecal Occult Blood Testing. 80.5% of residents had intentions to do Testing in the next six months, and 83.6% had behavioral intentions in the next two years. Attitude and behavior attitude had a significant positive correlation (r = 0.838, p <0.001). Women, residents with higher education, higher household income, having heard of fecal occult blood testing, with regular physical examinations and regularly using Fecal Occult Blood Testing had higher behavioral intentions. Under the control of social demographic variables, results found that subjective norm is the most important predictor variable (β = 0.549, p <0.001), followed by perceived behavioral control (β = 0.262, p <0.001), and behavioral attitude (β = 0.187, p <0.001) in the predicting model, three variables of the theory of planned behavior can explain 65.6% of variances of the intention of participating in Fecal Occult Blood Testing.
Conclusions and Recommendations: Intentions of community residents to participate in Fecal Occult Blood Testing are influenced by behavioral attitude, perceived behavioral control and subjective norm, of which subjective norm has the greatest influence on intentions. Screening is an effective preventive method to promote health. A preventive program by health professionals or staffs of cancer associations, and encouragements of the family can help the community residents to comply with the behavior of Fecal Occult Blood Testing.
