Home-administered fecal occult blood test for colorectal cancer screening among worksites in Taiwan

Background. This study assessed the perceived acceptance, difficulty level, and screening efficacy of home-administered fecal occult blood test (FOBT) among a Chinese population. Methods. Participants (age 40 and above) were recruited at various worksites in Taiwan during the summer of 2002. A single group pretest and posttest design was used. Results. The 1-month follow up rate was 81% (304/375). Screening result return rate (76%) and FOBT completion rate (74%) using the home-administered kit (HAK) were both high. Intention towards FOBT in the coming year significantly increased after the intervention (P < 0.001). At pretest, participants demonstrated higher perceived acceptance and screening completion efficacy of FOBT using home-administered kit (HAK) than the traditional method (P < 0.001). At posttest, the perceived difficulty of FOBT using HAK was significantly lower than the traditional stool-collecting method (P < 0.001). While the acceptance of HAK remained high both before and after the intervention, the acceptance and screening efficacy towards traditional FOBT decreased significantly (P < 0.001). Conclusions. This study showed the great potential of using home-administered FOBT to promote colorectal cancer (CRC) screening among a Chinese population. Future intervention using innovative screening strategies will need to consider the participantʹs stage of adoption and cultural beliefs related to screening and preventive behaviors.
