title: Factors associated with adherence to fecal occult blood testing for colorectal cancer screening among adults in the Republic of Korea.
abstract: OBJECTIVE
  Repeated participation in fecal occult blood testing (FOBT) is one of the major factors affecting the long-term success of population-based colorectal cancer screening programs. The aim of this study is to explore strong factors linked to repeated participation in FOBT in the prior decade (2002-2011) among adults using the Health Belief Model (HBM) after controlling for other covariates.
  
  
  METHODS
  Data were obtained from South Korean adults, aged 50 years and over, who visited a national health screening center within a magnet hospital (N = 237). A pilot test was conducted to investigate the internal consistency of the HBM instruments and the clarity of survey questions. Sample characteristics and rates of adherence to FOBT screening were examined using means and frequencies. Important factors associated with adherence to FOBT were examined using multivariate logistic regression analysis.
  
  
  RESULTS
  About 44% of the respondents were adherent to FOBT screening over the prior decade. Four out of the six HBM-driven factors (perceived susceptibility, severity, and barriers, and health motivation) were statistically significant. Those with greater levels of susceptibility and health motivation and lower levels of severity and barriers were more likely to adhere to FOBT.
  
  
  CONCLUSIONS
  Health professionals should focus more on the four modifiable HBM-related factors to encourage adults to adhere to FOBT. Intervention programs, which lower perceived severity and barriers and increase susceptibility and health motivation, should be developed and implemented.
