No Time for Waste! Co‐Producing Practice Guidelines and Research Recommendations to Promote Earlier Diagnosis of Colorectal Cancer in Community Pharmacies
INTRODUCTION: In the United Kingdom, community pharmacists (CPs) are increasingly being used to provide supplemental care for patients with specific conditions while the NHS is under pressure from declining GP numbers alongside a rising demand for services. CPs are ideally placed to contribute to early diagnosis of colorectal cancer (CRC) through extended services, especially amongst deprived areas where access is higher across all deprivation de…
Effectiveness of behavior change techniques to address barriers to follow-up colonoscopy
BACKGROUND: Nonattendance at colonoscopy is associated with reduced colorectal cancer (CRC) survival. PURPOSE: The aim of this research was to quantify barriers to colonoscopy and test the effectiveness of behavior change techniques (BCTs) to address them. METHODS: Two studies were conducted. In the first study, participants were asked to imagine their next CRC screening result was abnormal, and were presented with the standard abnormal result le…
Impact of screening participation on modelled mortality benefits of a multi-cancer early detection test by socioeconomic group in England
BACKGROUND: Cancer burden is higher and cancer screening participation is lower among individuals living in more socioeconomically deprived areas of England, contributing to worse health outcomes and shorter life expectancy. Owing to higher multi-cancer early detection (MCED) test sensitivity for poor-prognosis cancers and greater cancer burden in groups experiencing greater deprivation, MCED screening programmes may have greater relative benefit…
Offering disinclined people the choice between different screening appointments
OBJECTIVES: An invitation to cancer screening with a single (fixed) appointment time has been shown to be a more effective way at increasing uptake compared with an invitation with an open (unscheduled) appointment. The present study tested whether offering more than one fixed appointment could further enhance this effect or be detrimental to people's intention. DESIGN: Experimental online hypothetical vignette survey. METHODS: 1,908 respondents …
Ethnic inequalities in older adults bowel cancer awareness
Awareness of bowel cancer symptoms, risk factors and screening varies by ethnicity. Interventions should be targeted towards specific groups for whom awareness of screening and risk factors is low
Testing Enhanced Active Choice to Optimize Acceptance and Participation in a Population-Based Colorectal Cancer Screening Program in Malta
Opt-out strategies have been shown to improve participation in cancer screening; however, there are ethical concerns regarding the presumed consent. In this study, we tested an alternative opt-in strategy, called: "enhanced active choice," in which the response options summarize the consequences of the decision. The study was conducted as part of the Maltese colorectal cancer screening program, which offers men and women, aged 60-64, a "one-off" …
Testing verbal quantifiers for social norms messages in cancer screening
Verbal quantifiers can be used to improve the perception of low uptake figures and avoid a demotivating effect
Barriers to bowel scope (flexible sigmoidoscopy) screening
Interventions to improve BSS uptake should be more nuanced and use targeted strategies to address the specific needs of each group
A lack of information engagement among colorectal cancer screening non-attenders
Although 'The Facts' booklet is intended to support informed choices about CRC screening, the majority of unscreened individuals report that they have read none of it. The degree to which public engagement with the decision-making process about cancer screening is socially unequal must be better understood so that comprehensive and equitable public communication strategies can be developed
Aging and Functional Health Literacy
The associations between objective numeracy and colorectal cancer screening knowledge, attitudes and defensive processing in a deprived community sample
We examined associations between numeracy and sociocognitive factors associated with colorectal cancer screening uptake ( n = 964). Nearly half (45.7%) of the respondents incorrectly answered a numeracy question (low numeracy). Low numeracy respondents were less knowledgeable about colorectal cancer ( p < .001), less positive towards screening (emotional, p < .001 and practical, p = .001) and less likely to intend to participate in screening ( p …
How do people interpret information about colorectal cancer screening
BACKGROUND: The English NHS Bowel Cancer Screening Programme biennially invites individuals aged 60-74 to participate in screening. The booklet, 'Bowel Cancer Screening: The Facts' accompanies this invitation. Its primary aim is to inform potential participants about the aims, advantages and disadvantages of colorectal cancer screening. OBJECTIVE: To provide detailed commentary on how individuals process the information contained within 'The Fact…
Supplementing factual information with patient narratives in the cancer screening context
OBJECTIVE: To explore people's responses to narrative information in the context of colorectal cancer screening. DESIGN: Nineteen in-depth interviews were conducted with men and women (aged 45-59). Participants were given two types of colorectal screening information to read: factual and narrative. Participants gave their views on both types of information. Data were analysed using Framework Analysis. RESULTS: The most frequent responses to the n…
Understanding low colorectal cancer screening uptake in South Asian faith communities in England – a qualitative study
Efforts to increase accessibility to colorectal cancer screening in South Asian communities should use local language broadcasts on ethnic media and face-to-face approaches within community and faith settings to increase awareness of colorectal cancer and screening, and address challenges posed by written materials

Internet use, social engagement and health literacy decline during ageing in a longitudinal cohort of older English adults
BACKGROUND: Health literacy skills tend to decline during ageing, which is often attributed to age-related cognitive decline. Whether health literacy skills may be influenced by technological and social factors during ageing is unknown. METHODS: We investigated whether internet use and social engagement protect against health literacy decline during ageing, independent of cognitive decline. We used prospective data from 4368 men and women aged ≥5…
Decomposing socio-economic inequality in colorectal cancer screening uptake in England
Responses to procedural information about colorectal cancer screening using faecal occult blood testing
Background Colorectal cancer (CRC) screening participation is low despite its effectiveness in reducing CRC mortality. Identifying benefits and barriers requires consideration of specific characteristics of screening modalities. Aims and Research Questions To monitor the impact of providing information about CRC screening via faecal occult blood testing (FOBt) on intentions to participate. To investigate moderation by individual differences in co…
Choosing between CT colonography and colonoscopy in the diagnostic context
Objective To explore information needs and preferences on diagnostic bowel tests and elicit preferences for CT colonography (CTC) vs. colonoscopy (CC). Background CTC is a new technology for large‐bowel imaging that has been widely assumed to be more acceptable than CC because it is non‐invasive. Design Semi‐structured focus groups discussing information choices and procedure preferences. Setting and participants Non‐patient sample of 26 asymptom…
Functional health literacy and health-promoting behaviour in a national sample of British adults
OBJECTIVES: To measure the prevalence of limited functional health literacy in the UK, and examine associations with health behaviours and self-rated health. DESIGN: Psychometric testing using a British version of the Test of Functional Health Literacy in Adults (TOFHLA) in a population sample of adults. SETTING: UK-wide interview survey (excluding Northern Ireland and the Scottish Isles). PARTICIPANTS: 759 adults (439 women, 320 men) aged 18-90 …
