title: Participation in a sigmoidoscopic colorectal cancer screening program: a pilot study.
abstract: At present, very little is known about the determinants of endoscopic screening participation. This study presents an analysis of the psychosocial associations of participation and nonparticipation in a sigmoidoscopic colorectal cancer screening program. The present pilot study was executed among members of a Dutch target group, ages 50-60 years, who visited an internal medicine outpatient clinic. Individuals who were asked to participate in the program (n = 200) received general information with regard to the screening procedure. The participation rate was 45%. Persons who participated in the screening program as well as those who wanted to participate in the study but did not want to participate in the screening program were asked to fill out a questionnaire. Self-efficacy, i.e., the individual's perception of the difficulty of participating in the screening program, appeared to be the most important association of participation. Furthermore, response efficacy, i.e., the individual's beliefs about the outcome of participation, and social support proved to be concepts that were associated with participation.
