Zusammenfassung: | Objective: To determine the effect of certain personal and health behaviour characteristics on participation in a community‐based colorectal neoplasia (CRN) screening program using virtual colonoscopy.
Methods: The study population comprised randomly selected subjects from the State electoral roll; screening by virtual colonoscopy was offered through letter of invitation. For non‐responders, a further invitation was sent a month later. Non‐response after a further month led to subjects being considered non‐participants. Non‐participants were contacted by letter to complete a structured questionnaire; participants completed a similar questionnaire immediately after their screening virtual colonoscopy.
Results: Discussing the invitation to screening with someone else increased the likelihood of participation by 63% (prevalence ratio 1.63, 95% CI 1.38–1.93); knowing someone with cancer increased the likelihood of participation by 23% (PR 1.23, 95% CI 1.07–1.42). Among participants who discussed screening with another individual, the spouse was the most common (71%). Subjects who were single were less likely to participate (PR 0.79, 95% CI 0.67–0.94). The strongest reported influence for participation was information provided in the letter of invitation (29.8%). The most common reasons for non‐participation were lack of time and perceived good health.
Conclusions and Implications: This study suggests that a simple strategy to facilitate participation is to encourage subjects to discuss screening with others; further, to recognise that this may be most difficult for those who are single. Information provided to subjects prior to screening positively contributes to participation. |
