Abstract

Background: Cancer fear has been associated with higher and lower screening uptake across different studies, possibly because different aspects of cancer fear have different effects on intentions versus behavior. The present study examined associations of three aspects of cancer fear with intention and uptake of endoscopic screening for colorectal cancer.

Methods: A subsample of UK Flexible Sigmoidoscopy (FS) Trial participants received a baseline questionnaire that included three cancer fear items from a standard measure asking if: (i) cancer was feared more than other diseases, (ii) cancer worry was experienced frequently, and (iii) thoughts about cancer caused discomfort. Screening intention was assessed by asking participants whether, if invited, they would accept an invitation for FS screening. Positive responders were randomized to be invited or not in a 1:2 ratio. The behavioral outcome was clinic-recorded uptake. Control variables were age, gender, ethnicity, education, and marital status.

Results: The questionnaire return rate was 60% (7,971/13,351). The majority (82%) intended to attend screening; 1,920 were randomized to receive an invitation, and 71% attended. Fearing cancer more than other diseases (OR = 2.32, P < 0.01) and worrying a lot about cancer (OR = 2.34, P < 0.01) increased intentions to attend screening, but not uptake. Finding thoughts about cancer uncomfortable did not influence intention, but predicted lower uptake (OR = 0.72, P < 0.01).

Conclusions: Different aspects of cancer fear have different effects on the decision and action processes leading to screening participation.

Impact: Knowledge of the different behavioral effects of cancer fear may aid the design of effective public health messages.
