Financial Incentives to Increase Colorectal Cancer Screening Uptake and Decrease Disparities

IMPORTANCEColorectal cancer screening rates are suboptimal, particularly among sociodemographically disadvantaged groups.OBJECTIVETo examine whether guaranteed money or probabilistic lottery financial incentives conditional on completion of colorectal cancer screening increase screening uptake, particularly among groups with lower screening rates.DESIGN, SETTING, AND PARTICIPANTSThis parallel, 3-arm randomized clinical trial was conducted from March 13, 2017, through April 12, 2018, at 21 medical centers in an integrated health care system in western Washington. A total of 838 age-eligible patients overdue for colorectal cancer screening who completed a questionnaire that confirmed eligibility and included sociodemographic and psychosocial questions were enrolled.INTERVENTIONSInterventions were (1) mail only (n = 284; up to 3 mailings that included information on the importance of colorectal cancer screening and screening test choices, a fecal immunochemical test [FIT], and a reminder letter if necessary), (2) mail and monetary (n = 270; mailings plus guaranteed $10 on screening completion), or (3) mail and lottery (n = 284; mailings plus a 1 in 10 chance of receiving $50 on screening completion).MAIN OUTCOMES AND MEASURESThe primary outcome was completion of any colorectal cancer screening within 6 months of randomization. Secondary outcomes were FIT or colonoscopy completion within 6 months of randomization. Intervention effects were compared across sociodemographic subgroups and self-reported psychosocial measures.RESULTSA total of 838 participants (mean [SD] age, 59.7 [7.2] years; 546 [65.2%] female; 433 [52.2%] white race and 101 [12.1%] Hispanic ethnicity) were included in the study. Completion of any colorectal screening was not significantly higher for the mail and monetary group (207 of 270 [76.7%]) or the mail and lottery group (212 of 284 [74.6%]) than for the mail only group (203 of 284 [71.5%]) (P = .11). For FIT completion, interventions had a statistically significant effect (P = .04), with a net increase of 7.7% (95% CI, 0.3%–15.1%) in the mail and monetary group and 7.1% (95% CI, −0.2% to 14.3%) in the mail and lottery group compared with the mail only group. For patients with Medicaid insurance, the net increase compared with mail only in FIT completion for the mail and monetary or the mail and lottery group was 37.7% (95% CI, 11.0%–64.3%) (34.2% for the mail and monetary group and 40.4% for the mail and lottery group) compared with a net increase of only 5.6% (95% CI, −0.9% to 12.2%) among those not Medicaid insured (test for interaction P = .03).CONCLUSIONS AND RELEVANCEFinancial incentives increased FIT uptake but not overall colorectal cancer screening. Financial incentives may decrease screening disparities among some sociodemographically disadvantaged groups.TRIAL REGISTRATIONClinicalTrials.gov identifier:

Study protocol for developing #CuttingCRC: a barbershop-based trial on masculinity barriers to care and colorectal cancer screening uptake among African-American men using an exploratory sequential mixed-methods design

IntroductionColorectal cancer (CRC) is preventable, as screening leads to the identification and removal of precancerous polyps. African-American men consistently have the highest CRC mortality rates, and their CRC-screening uptake remains...

Colorectal Cancer Screening in People With and Without HIV in an Integrated Health Care Setting.

As people with HIV (PWH) live longer, age-appropriate colorectal cancer (CRC) screening is increasingly important. Limited data exist on CRC screening and outcomes comparing PWH and persons without HIV. Large integrated health care system. This study included PWH and demographically matched persons without HIV who were aged 50-75 years during 2005-2016 and had no previous CRC screening. We evaluated time to first CRC screening (fecal test, sigmoidoscopy, or colonoscopy). We also assessed detection of adenoma and CRC with sigmoidoscopy or colonoscopy by HIV status, accounting for CRC risk factors including sex, age, race/ethnicity, number of outpatient visits, smoking, body mass index, type-2 diabetes, and inflammatory bowel disease. Among PWH, we evaluated whether CD4 count (<200/200-499/≥500 cells/µL) was associated with adenoma and CRC. Among 3177 PWH and 29,219 persons without HIV, PWH were more likely to be screened (85.6% vs. 79.1% within 5 years, P < 0.001). Among those with sigmoidoscopy or colonoscopy, adenoma was detected in 161 (19.6%) PWH and 1498 (22.6%) persons without HIV, and CRC was detected in 4 (0.5%) PWH and 69 (1.0%) persons without HIV. In adjusted analyses, we found no difference in prevalence of either adenoma or CRC by HIV status (adjusted prevalence ratio = 0.97, 95% confidence interval: 0.83 to 1.12). Lower CD4 count did not increase likelihood of adenoma or CRC. Within an integrated health care system with an organized CRC screening program, we found no disparities in CRC screening uptake or outcomes among people with and without HIV, and CD4 count did not influence CRC risk among PWH.

The influence of environmental and health indicators on premature mortality: An empirical analysis of the City of Toronto's 140 neighborhoods.

The objective of this paper was to assess the link between premature mortality and a combination of neighbourhood contextual (environmental and health) and compositional (socioeconomic and demographic) characteristics. We statistically and spatially examined six environmental variables (ultrafine particles, carcinogenic and non-carcinogenic pollutants, pollution released to air, tree cover, and walkability index), six health service indicators (number health providers, breast, colorectal and cervical cancer screening uptake rates, student nutrition program uptake rates, and healthy food index), and eight socioeconomic indicators (total income, Gini coefficient, two age categories - below and above 40 years, proportion of females to males, visible minorities, Indigenous peoples, education, less than grade 9) among 140 neighbourhoods of the City of Toronto in Ontario (Canada). We applied principal component analysis to identify patterns and to reduce the number of explanatory variables into combined component axes that represent unique variation in these confounded and overlapping factors. We then applied regression analysis to model the relationship between the indices of enviro-health and socioeconomics and their potential relationship with premature mortality. Residual spatial analysis was used to investigate any remaining spatial structure (such as neighbourhoods with higher residual premature mortality rates). Neighbourhood Equity Index was correlated with our enviro-health and socioeconomic indices. Premature mortality within neighbourhoods was predicted by poor cancer screenings, pollution, lack of tree canopy, increased uptake of student nutrition programs and high walkability index. A negative association between premature mortality and pollution was associated low walkability index and presence of visible minorities within neighbourhoods. There was some unexplained residual spatial variation in our model of premature mortality - especially along the shores of Lake Ontario and in neighbourhoods with major highways or road corridors: premature mortality in Toronto neighbourhoods was higher than expected along highway-corridor neighbourhoods and shorelines. Our analysis revealed a significant relationship between neighbourhood contextual features - both environmental and health - and premature mortality, suggesting that these contextual components of neighbourhoods can predict rates of urban premature mortality in Toronto.

Using a continuum of hybrid effectiveness-implementation studies to put research-tested colorectal screening interventions into practice

BackgroundFew previous studies have applied the hybrid effectiveness-implementation design framework to illustrate the way in which an intervention was progressively implemented and evaluated across multiple studies in diverse settings.MethodsWe describe the design components and methodologies of three studies that sought to improve rates of colorectal cancer (CRC) screening using mailed outreach, and apply domains put forth by Curran et al.: research aims, research questions, comparison conditions, sample, evaluation methods, measures, and potential challenges.The Hybrid 1 study (emphasis on effectiveness) was a patient-level randomized trial of a mailed fecal test and stepped phone-outreach intervention program delivered in an integrated healthcare system (21 clinics, 4673 patients). The primary outcome was effectiveness (CRC screening uptake). Implementation outcomes included cost-effectiveness and acceptability.The Hybrid 2 study (shared emphasis on effectiveness and implementation) was a pragmatic cluster-randomized trial of mailed fecal immunochemical test (FIT) outreach implemented at safety net clinics (26 clinics, 41,000 patients). The intervention used electronic health record tools (adapted from Hybrid 1) and clinic personnel to deliver the intervention. Outcomes included effectiveness (FIT completion) and implementation (FIT kits delivered, clinic barriers and facilitators, cost-effectiveness).Hybrid 3 study (emphasis on implementation) is a demonstration project being conducted by two Medicaid/Medicare insurance plans (2 states, 12,000 patients) comparing two strategies for implementing mailed FIT programs that addressed Hybrid 2 implementation barriers. Outcomes include implementation (activities delivered, barriers) and effectiveness (FIT completion).ResultsThe effectiveness-implementation typology successfully identified a number of distinguishing features between the three studies. Two additional features, program design and program delivery, varied across our studies, and we propose adding them to the current typology. Program design and program delivery reflect the process by which and by whom a program is designed and delivered (e.g., research staff vs. clinic/health plan staff).ConclusionsWe describe three studies that demonstrate the hybrid effectiveness to implementation continuum and make recommendations for expanding the hybrid typology to include new descriptive features. Additional comparisons of Hybrid 1, 2, and 3 studies may help confirm whether our hybrid typology refinements are generalizable markers of the pipeline from research to practice.

A family-based multimedia intervention to enhance the uptake of colorectal cancer screening among older South Asian adults in Hong Kong: a study protocol for a cluster randomized controlled trial

BackgroundColorectal cancer (CRC) screening, such as fecal occult blood test (FOBT), is an effective way to prevent CRC, one of the most common cancers worldwide. However, studies found that South Asian ethnic minorities tend not to utilize CRC screening, whose importance on CRC prevention shall be educated among those from ethnic minorities, especially older adults. The purpose of this study is to develop and implement a family-based, multimedia intervention to augment the knowledge of CRC prevention among older South Asian adults in Hong Kong and enhance their motivation for undergoing FOBT. The acceptability and effectiveness of the intervention will be assessed using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework.MethodsA cluster randomized controlled trial will be carried out. Three hundred and twenty South Asian dyads, comprising an older adult aged between 50 and 75 and a younger family member aged between 18 and 49, will be recruited in ten districts in Hong Kong through community organizations that provide support services for South Asians in local communities. Dyads will be randomly allocated to either the intervention or wait-list control group. Intervention dyads will receive intervention, whose contents are based on the health belief model, via multiple forms of media including PowerPoint presentation, video clip and health information booklet. Control dyads will receive intervention after post-intervention data are collected. For dyads in both groups, an appointment with a family doctor will be arranged for those willing to undergo FOBT. Outcomes will be assessed at baseline and post-intervention. Data will be analysed using the Generalised Linear Models Procedure in an intention-to-treat manner.DiscussionFindings of this study will provide evidence of the benefits of utilizing multimedia and family-based approaches in intervention development to enhance the effectiveness of health promotion interventions for ethnic minorities. Further, the findings would provide reference to the potential incorporation of the intervention in the existing support services for South Asian ethnic minorities in local communities.Trial registrationThis trial is registered at the ISRCTN Registry (ISRCTN72829325) on 19th July 2018.

Cancer worry frequency vs. intensity and self-reported colorectal cancer screening uptake: A population-based study.

ObjectivesMany studies of cancer worry use items measuring frequency or intensity. Little is known about how each of these relate to cancer screening uptake. This study compared the association between worry frequency vs. intensity and colorectal cancer screening intention/uptake.MethodsAcross four surveys (2014–2016), we collected data from 2878 screening-eligible men and women (aged 60–70) in England. Measures included single-items assessing cancer worry frequency and intensity, and a derived combination of both. We also assessed self-reported past faecal occult blood testing uptake (ever vs. never), intention to participate when next invited (yes vs. no), and demographics. Using logistic regression, we compared a model containing sociodemographic characteristics (Model 1), with four models adding cancer worry frequency (Model 2), intensity (Model 3), both (Model 4), or the combined measure (Model 5).ResultsA model with cancer worry intensity and demographics (Model 3) explained significantly more variance in uptake and intention (R2 = 0.068 and 0.062, respectively) than demographics alone (Model 1: R2 = 0.058 and 0.042; p < 0.001), or a model with demographics and cancer worry frequency (Model 2: R2 = 0.059 and 0.052; p < 0.001). The model was also equally as effective as models including both the frequency and intensity items (Model 4: R2 = 0.070 n.s. and 0.062 n.s.), or using the derived combination of both (Model 5: R2 = 0.063 n.s. and 0.053 n.s.).ConclusionA single item measure of cancer worry intensity appeared to be most parsimonious for explaining variance in colorectal cancer screening intention and uptake.

Knowledge, attitudes, and worries among different health literacy groups before receiving first invitation to colorectal cancer screening: Cross-sectional study.

BackgroundColorectal cancer screening uptake is associated with knowledge, attitudes and worries about screening. People with higher levels of health literacy usually have higher screening-related knowledge, but its association with attitudes and worries is sparsely described.The aim of this study was to describe knowledge, attitudes, and worries about colorectal cancer screening among unscreened citizens, and to estimate the association between these and health literacy.MethodsIn a cross-sectional study 10,030 53–74 year-old Central Denmark Region citizens received a questionnaire assessing knowledge, attitudes, worry and health literacy. Socioeconomic and –demographic data were linked from Statistics Denmark after data collection.ResultsIn total, 7142 (71.2%) questionnaires were completed. A good general level of knowledge was observed (4.91 and 5.13 out of 7 for men and women, respectively). Citizens tended to be positive towards screening (21.4 and 21.3 on a 4–28 range scale for men and women respectively), and showed low levels of worries (8.8 and 9.09 on a 3–15 range scale for men and women respectively). Knowledge decreased and worries increased with lower levels of health literacy. Further, attitudes tended to be more positive with higher levels of health literacy.ConclusionsIn general, citizens tend to have good knowledge, positive attitudes and few worries about colorectal cancer screening. People with lower health literacy could benefit from targeted interventions that address knowledge and worries about screening to support informed decision making.

A culturally and linguistically salient pilot intervention to promote colorectal cancer screening among Latinos receiving care in a Federally Qualified Health Center.

Despite established benefits, colorectal cancer (CRC) screening is underutilized among Latinos/Hispanics. We conducted a pilot 2-arm randomized controlled trial evaluating efficacy of two intervention conditions on CRC screening uptake among Latinos receiving care in community clinics. Participants (N = 76) were aged 50-75, most were foreign-born, preferred to receive their health information in Spanish, and not up-to-date with CRC screening. Participants were randomized to either a culturally linguistically targeted Spanish-language fotonovela booklet and DVD intervention plus fecal immunochemical test [FIT] (the LCARES, Latinos Colorectal Cancer Awareness, Research, Education and Screening intervention group); or a non-targeted intervention that included a standard Spanish-language booklet plus FIT (comparison group). Measures assessed socio-demographic variables, health literacy, CRC screening behavior, awareness and beliefs. Overall, FIT uptake was 87%, exceeding the National Colorectal Cancer Roundtable's goal of 80% by 2018. The LCARES intervention group had higher FIT uptake than did the comparison group (90% versus 83%), albeit not statistically significant (P = 0.379). The LCARES intervention group was associated with greater increases in CRC awareness (P = 0.046) and susceptibility (P = 0.013). In contrast, cancer worry increased more in the comparison group (P = 0.045). Providing educational materials and a FIT kit to Spanish-language preferring Latinos receiving care in community clinics is a promising strategy to bolster CRC screening uptake to meet national targets.

Mailed Outreach Is Superior to Usual Care Alone for Colorectal Cancer Screening in the USA: A Systematic Review and Meta-analysis.

Mailed outreach promoting colorectal cancer (CRC) screening with a stool blood test kit may increase participation, but magnitude and consistency of benefit of this intervention strategy is uncertain. Our aim was toconduct a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing mailed outreach offering stool tests to usual care, clinic-based screening offers on CRC screening uptake in the USA. We performed a systematic literature search of five databases for RCTs of mailed outreach from January 1980 through June 2017. Primary outcome was screening completion, summarized using random-effects meta-analysis as pooled differences in proportion completing the screening and relative risk of achieving screening compared to control. Subgroup analyses by test type offered-fecal immunochemical test (FIT) or guaiac fecal occult blood test (gFOBT), the presence of telephone reminders, and the presence of predominant underserved/minority population within study were performed. Quality of evidence was evaluated using the GRADE framework. Seven RCTs which enrolled 12,501 subjects were included (n = 5703 assigned mailed outreach and n = 6798 usual care). Mailed outreach resulted in a 28% absolute (95% CI 25-30%; I2 = 47%) and a 2.8-fold relative (RR 2.65, 95% CI 2.03-3.45; I2 = 92%) increase in screening completion compared to usual care, with a number needed to invite estimated to be 3.6. Similar outcomes were observed across subgroups. Overall body of evidence was at moderate quality. Mailed outreach offering a gFOBT or FIT is associated with a large and consistent increase in CRC screening completion and should be considered for more widespread implementation for improving screening rates nationwide.

Does the Flemish colorectal cancer screening programme reach equity in FIT uptake?

To investigate colorectal cancer (CRC) screening rates by the faecal immunochemical test (FIT) according to sociodemographic characteristics and nationality. Men and women, aged 56-74, invited to participate in the Flemish CRC screening programme in 2013 and 2014 were included in this study. We analysed the association between CRC screening uptake and sex, age, (first and current) nationality and several proxies for socio-economic status (SES). The statistical analysis was based on descriptive analyses and logistic regression models. A total of 1 184 426 persons were included in our analysis. The overall screening uptake was 52.3%, uptake varied by sex, age, nationality and SES. Lower participation rates were associated with the youngest and oldest age categories (56-60 and 70-74) and being male. All nationalities other than Belgian or Dutch were significantly less screened. Lower uptake of screening was also associated with several proxy's for low SES, such as having an allowance for being disabled, not being able to work, being an extended minor and having a social allowance/minimum wage. The descriptive analysis showed a 27% difference in CRC screening uptake between the (early) retired and the people entitled to a minimum wage. There is a significant difference between screening uptake and demographic and socio-economic variables in the first 2 years of the population-based screening programme in Flanders. Based on the study results, implementing strategies to improve participation in those subgroups is needed.

Viewpoints of the target population regarding barriers and facilitators of colorectal cancer screening in the Czech Republic.

BACKGROUNDPublic awareness of colorectal cancer (CRC) and uptake of CRC screening remain challenges. The viewpoints of the target population (asymptomatic individuals older than 50) regarding CRC screening information sources and the reasons for and against participation in CRC screening are not well known in the Czech Republic. This study aimed to acquire independent opinions from the target population independently on the health system.AIMTo investigate the viewpoints of the target population regarding the source of information for and barriers and facilitators of CRC screening.METHODSA survey among relatives (aged 50 and older) of university students was conducted. Participants answered a questionnaire about sources of awareness regarding CRC screening, reasons for and against participation, and suggestions for improvements in CRC screening. The effect of certain variables on participation in CRC screening was analyzed.RESULTSOf 498 participants, 478 (96%) respondents had some information about CRC screening and 375 (75.3%) had participated in a CRC screening test. General practitioners (GPs) (n = 319, 64.1%) and traditional media (n = 166, 33.3%) were the most common information sources regarding CRC screening. A lack of interest or time and a fear of colonoscopy or positive results were reported as reasons for non-participation. Individuals aged > 60 years [adjusted odds ratio (aOR) = 2.30, 95% confidence interval (CI) (1.42-3.71), P = 0.001], females (aOR = 1.95, 95%CI (1.26-3.01) P = 0.003), and relatives of CRC patients (aOR = 4.17, 95%CI (1.82-9.58) P = 0.001) were more likely to participate in screening. Information regarding screening provided by physicians - GPs: (aOR = 8.11, 95%CI (4.90-13.41), P < 0.001) and other specialists (aOR = 4.19, 95%CI (1.87-9.38), P = 0.001) increased participation in screening. Respondents suggested that providing better explanations regarding screening procedures and equipment for stool capturing could improve CRC screening uptake.CONCLUSIONGPs and other specialists play crucial roles in the successful uptake of CRC screening. Reduction of the fear of colonoscopy and simple equipment for stool sampling might assist in improving the uptake of CRC screening.

Disparities in colorectal cancer screening in New York City: An analysis of the 2014 NYC Community Health Survey.

Background & AimsDisparities in colorectal cancer (CRC) screening uptake by race/ethnicity, socioeconomic status, and geography are well documented. We sought to further characterize the relationship between sociodemographic factors and up‐to‐date colonoscopy use in a diverse urban center using the 2014 New York City Community Health Survey (NYCCHS).MethodsWe examined overall colonoscopy uptake by race/ethnicity—with a particular interest in Asian and Hispanic subgroups—and used weighting to represent the entire 2014 NYC adult population. We also evaluated the association between 10 sociodemographic variables (age, sex, race/ethnicity, birthplace, home language, time living in the US, education, employment, income, and borough of residence) and colonoscopy use using univariable and multivariable logistic regression models.ResultsUp‐to‐date colonoscopy uptake was 69% overall with reported differences by racial/ethnic group, ranging from 44%‐45% for Mexicans and Asian Indians to 75% for Dominicans. In the multivariable regression model, colonoscopy use was associated with age greater than 65 years, Chinese language spoken at home, and not being in the labor force. Lower colonoscopy use was associated with living in the US for less than 5 years, Asian Indian language spoken at home, lower income, and residing outside of Manhattan.ConclusionsAmong New Yorkers older than age 50, up‐to‐date colonoscopy use varied significantly by race/ethnicity, especially in Asian and Hispanic subgroups. Recent immigrants, low‐income groups, and those living outside of Manhattan were significantly less likely to receive CRC screening. Targeted interventions to promote CRC screening in these underserved groups may improve overall screening uptake.

Performance of a MethyLight assay for methylated SFRP2 DNA detection in colorectal cancer tissue and serum.

Colorectal cancer is one of the five most common cancers in China, and its incidence is steadily increasing. An accurate and non-invasive screening method is needed to increase the population uptake of colorectal cancer screening. Secreted frizzled-related protein 2 ( SFRP2) has been found to be hypermethylated in most colorectal cancer patients, and it may fulfill the role of a non-invasive biomarker for colorectal cancer screening. Methylation status of SFRP2 was examined in 17 cancer tissues and paired adjacent paracancer tissues by a new SFRP2 MethyLight assay, which was also used to test the serum of 62 patients with colorectal cancer and 55 normal individuals. The limit of detection of the SFRP2 MethyLight assay was about 200 pg per reaction. The SFRP2 methylation level was higher in 94.1% colorectal cancer tissues than in paired adjacent paracancer tissues ( P<0.001). The sensitivity and specificity of SFRP2 for detecting colorectal cancer in serum were 69.4% (95% confidence interval (CI) 56.2, 80.1%) and 87.3% (95% CI 74.9, 94.3%), respectively. SFRP2 methylation in serum has the potential to be a non-invasive biomarker for colorectal cancer screening.

Impact on immigrant screening adherence with introduction of a population-based colon screening program in Ontario, Canada.

IntroductionThe literature suggests that differential colorectal cancer (CRC) screening adherence exists between Canada’s immigrant and nonimmigrant populations. This study explores the impact of Ontario’s population screening program, ColonCancerCheck, on CRC screening uptake in immigrant and nonimmigrant population groups.MethodsData from 2005, 2007‐2008, and 2011‐2012 was obtained from the Canadian Community Health Survey, to represent the intervention periods (the time periods before, during, and after implementation of the ColonCancerCheck intervention). Multivariable logistic regression was used to examine the effect of immigration status on the risk of nonadherence to guideline‐recommended CRC screening, and an interaction analysis was performed to determine whether the screening differential between immigrant and nonimmigrant populations changed upon introduction of the ColonCancerCheck program.ResultsRecent and long‐term immigrants were both at increased risk of CRC screening nonadherence compared to the Canadian‐born population (OR 3.73 (CI 2.25‐6.18) and OR 1.24 (CI 1.13‐1.36), respectively). While not statistically significant, there was an attenuation of the risk of nonadherence to screening for recent immigrants compared with Canadian‐born individuals after the implementation of the ColonCancerCheck program.ConclusionsThis study provides evidence of a screening differential between immigrants and nonimmigrants, and suggests that the implementation of the ColonCancerCheck screening program in Ontario may have increased colon screening uptake amongst recent immigrants. Further studies are needed to address the factors leading to inequities in immigrant CRC screening adherence.

Improving Adherence to Colorectal Cancer Screening: A Randomized Intervention to Compare Screener vs. Survivor Narratives

Interventions are needed to increase colorectal cancer screening (CRCS) uptake. Narratives may have advantages over didactic information. We tested different narratives for increasing CRCS intentions and behaviors, and examined their mechanisms of influence. We randomized 477 unscreened adults 50–75 years old to one of three groups: CRCS information only (1) or CRCS information plus a photo and text narrative of a CRC survivor (2) or CRC screener who did not have cancer (3). Photos were tailored on participants’ sex, age group, and race/ethnicity. Participants completed online surveys before and after intervention exposure, and 1-, 6-, and 12-months follow-up. Thirty percent of participants completed CRCS. Narrative conditions (vs. information only) were negatively associated with intention, but also positively influenced intentions through greater emotional engagement. Survivor (vs. screener) narratives were positively associated with CRCS, and had mixed effects on intention – positively through emotional engagement and negatively through self-referencing engagement to self-efficacy. Survivor narratives elicited more negative affect, which had positive and negative influences on intention. Continued research using path models to understand the mechanisms of narrative effects will inform theory development and message design. Additional measurement evaluation is needed to adequately capture and then compare the effects of different components of narrative engagement.

Associations between cervical, breast and colorectal cancer screening uptake, chronic diseases and health-related behaviours: Data from the Italian PASSI nationwide surveillance

Screening programmes have been proposed as a privileged setting for health promotion interventions. We aim to assess the associations between behavioural risk factors, chronic conditions and diseases and cervical, breast and colorectal cancer screening uptake. Secondly, we aim to assess whether these associations are due to underlying differences in socioeconomic characteristics.In Italy, a random sample was interviewed by the PASSI surveillance (106,000 interviews) in 2014–2016. Screening uptake adjusted for age and gender alone and for age, gender and socioeconomic characteristics (educational attainment and self-reported economic difficulties) were estimated using multivariate Poisson regression models.Screening uptake was 79%, 73% and 45% for cervical (age 25–64), breast (women aged 50–69) and colorectal cancer (both sexes age 50–69), respectively. People with low consumption of vegetables and fruits and those with insufficient physical activity had lower uptake than people with healthy behaviours (20–22% and 8–15% lower, respectively), as did those obese and diabetic compared to healthier people (7–10% and 5–8% lower, respectively). Those with high-risk drinking behaviour, self-reported driving after drinking alcohol, and former smokers had higher screening uptake (3–7%, 3–6%, and 7–14% higher, respectively). Differences in uptake decreased after adjusting for socioeconomic characteristics, but trends were unvaried.In conclusion, screening uptake is negatively associated with unfavourable behaviours and health conditions that are also risk factors for breast and colorectal cancer incidence. Socioeconomic characteristics do not fully explain these differences. Health promotion interventions targeting diet and physical activity nested in screening programmes might miss part of the at-risk population.
