“…Following a previous study [ 27 ], attitudes towards CRC screening (screening interest, screening effectiveness, and trust in the result of screening) was measured by three close-ended questions for each of the three CRC screening tests as stated in the pamphlet [ 22 ]: FOBT, flexible sigmoidoscopy, and colonoscopy. The three close-ended questions are: Screening interest: “If you were offered a CRC screening test, would you take up the offer?” measured by a four-point Likert scale ranging from ‘Definitely Not’ to ‘Definitely Yes’; Screening effectiveness: “The bowel screening is effective in detecting bowel cancer” measured by a five-point Likert scale ranging from ‘Strongly Disagree’ to ‘Strongly Agree’; and Trust in the results of screening: “If you completed a screening test, would you trust the results of the test?” measured by a four-point Likert scale ranging from ‘Not At All’ to ‘Very Much’.…”

Colorectal cancer (CRC) screening is a cost-effective prevention and control strategy. However, the promotion of CRC screening for older adults may be difficult because reading CRC prevention information may evoke embarrassment, fear, and anxiety towards the screening procedure and cancer diagnosis. This study aims to (1) examine the effects of three promotional materials for CRC screening on the attitudes toward CRC screening tests (screening interest, screening effectiveness, and trust in the screening results) and cancer fear, and (2) to explore the interaction effect of cancer fear with screening effectiveness and trust in the screening results on screening interest of the three screening tests (fecal occult blood test (FOBT), flexible sigmoidoscopy, and colonoscopy) among Chinese older adults. A total of 114 community-dwelling older adults were asked to look at the corresponding promotional materials (pamphlet, cartoon, and video) of one of the three study groups. The pamphlet and video represent convention strategies and the cartoon represents an innovative strategy. No significant difference was observed in the screening interest and cancer fear across groups. FOBT was the most preferred screening modality. The video group has a large proportion agreed screening effectiveness of flexible sigmoidoscopy than pamphlet and cartoon groups and trusted in the screening results for FOBT and flexible sigmoidoscopy than the pamphlet group. Logistic regression results showed that the effect of trust in the screening results on screening interest for colonoscopy was greater among participants with higher cancer fear than those with lower cancer fear level. In conclusion, the three promotional groups had produced similar results in their attitudes toward CRC screening and cancer fear. The use of cartoons may be a comparable approach with conventional methods in the promotion of CRC screening. Additional components that can arouse fear and boost response efficacy simultaneously might also be useful for the effective promotion of colonoscopy among Chinese older adults.

“…92,[117][118][119][120][121] Specifically, in a bowel cancer screening context, it has been shown to increase the prevalence of negative attitudes about bowel cancer screening. 122 At the same time, it is important that information is not so oversimplified that it is no longer accurate or fails to enable people to make an informed decision about screening. 123 Concerns that simplifying health information might disadvantage certain groups are alleviated by the finding that low literacy messages can improve knowledge even among more educated samples.…”

Objective: To reduce socioeconomic inequalities in uptake of the NHS BCSP ’ s guaiac faecal occult blood test (gFOBt) without compromising uptake in any socioeconomic group. Design: Workstream 1 explored psychosocial determinants of non-uptake of gFOBt in focus groups and interviews. Workstream 2 developed and tested four theoretically based interventions: (1) ‘ gist ’ information, (2) a ‘ narrative ’ leaflet, (3) ‘ general practice endorsement ’ (GPE) and (4) an ‘ enhanced reminder ’ (ER). Workstream 3 comprised four national cluster randomised controlled trials (RCTs) of the cost-effectiveness of each intervention. Methods: Interventions were co-designed with user panels, user tested using interviews and focus groups, and piloted with postal questionnaires. RCTs compared ‘ usual care ’ (existing NHS BCSP invitations) with usual care plus each intervention. The four trials tested: (1) ‘ gist ’ leaflet ( n = 163,525), (2) ‘ narrative ’ leaflet ( n = 150,417), (3) GPE on the invitation letter ( n = 265,434) and (4) ER ( n = 168,480). Randomisation was based on day of mailing of the screening invitation. The Index of Multiple Deprivation (IMD) score associated with each individual ’ s home address was used as the marker of socioeconomic circumstances (SECs). Change in the socioeconomic gradient in uptake (interaction between treatment group and IMD quintile) was the primary outcome. Screening uptake was defined as the return of a gFOBt kit within 18 weeks of the invitation that led to a ‘ definitive ’ test result of either ‘ normal ’ (i.e. no further investigation required) or ‘ abnormal ’ (i.e. requiring referral for further testing). Difference in overall uptake was the secondary outcome. Results: The gist and narrative trials showed no effect on the SECs gradient or overall uptake (57.6% and 56.7%, respectively, compared with 57.3% and 58.5%, respectively, for usual care; all p -values > 0.05). GPE showed no effect on the gradient ( p = 0.5) but increased overall uptake [58.2% vs. 57.5% in usual care, odds ratio (OR) = 1.07, 95% confidence interval (CI) 1.04 to 1.10; p < 0.0001]. ER showed a significant interaction with SECs ( p = 0.005), with a stronger effect in the most deprived IMD quintile (14.1% vs. 13.3% in usual care, OR = 1.11, 95% CI 1.04 to 1.20; p = 0.003) than the least deprived (34.7% vs. 34.9% in usual care OR = 1.00, 95% CI 0.94 to 1.06; p = 0.98), and higher overall uptake (25.8% vs. 25.1% in usual care, OR = 1.07, 95% CI 1.03 to 1.11; p = 0.001). All interventions were inexpensive to provide. Limitations: In line with NHS policy, the gist and narrative leaflets supplemented rather than replaced existing NHS BCSP information. This may have undermined their effect. Conclusions: Enhanced reminder reduced the gradient and modestly increased overall uptake, whereas GPE increased overall uptake but did not reduce the gradient. Therefore, given their effectiveness and very low cost, the findings suggest that implementation of both by the NHS BCSP would be beneficial. The gist and narrative results hig...
