Examining the role of perceived susceptibility on colorectal cancer screening intention and behavior

Exploring factors influencing outpatient radiology attendance based on Health Belief Model (HBM): A qualitative study

INTRODUCTION

Non-attendance for radiology outpatient appointments is a global issue and is associated with adverse clinical outcomes and operational inefficiencies. This paper aims to understand the underlying factors influencing outpatient radiology attendances based on the Health Belief Model (HBM).

METHODS

Purposive sampling was used to recruit patients (n=30) for in-depth semi-structured telephone interviews. Inclusion criteria comprised participants who were above 21 years old and fluent in English, while participants reliant on third-party assistance (e.g., nursing homes and prison services), to attend the appointment were excluded. The interviews were recorded and transcribed verbatim. The COREQ (Consolidated Criteria for Reporting Qualitative Research) was utilised to guide the reporting of this study. The data analysis involved a hybrid thematic analysis approach using NVivo.

RESULTS

Six key themes associated with appointment adherence in radiology were identified. These themes included: 1) prioritising health and acceptance of current medical conditions; 2) the impact of perceived severity on non-attendance; 3) perceived benefits of attending appointments; 4) perceived barriers to attendance; 5) influential prompts; and 6) confidence in attendance.

CONCLUSION

This is the first study of its kind to utilise the HBM to examine factors influencing attendance adherence among radiology outpatients in Singapore. Costs, prompts, and the perceived severity of the condition play pivotal roles in shaping the health-seeking behaviours of these outpatients while professionalism of healthcare staff and barriers to attendance present opportunities for providers to address patients' lack of interest towards their appointments.

IMPLICATIONS FOR PRACTICE

Findings of this study will contribute to the development of personalised, targeted interventions for improving patient engagement and attendance in radiology settings.

Psychosocial Risk Profiles and Colorectal Cancer Screening: A Latent Profile Analysis in a Colorectal Cancer Screening Intervention Setting

Health behavior theories have identified predictors of colorectal cancer screening. This study aimed to determine the psychosocial profiles of a predominantly Hispanic population of primarily Mexican origin receiving a colorectal cancer screening intervention and whether a specific combination of psychosocial profiles modified the effect of colorectal cancer screening intervention on colorectal cancer screening uptake.A total of 467 participants aged 50 to 75 years due for colorectal cancer screening received an educational intervention. Latent profile analysis (LPA) was performed on baseline psychosocial constructs to identify the homogenous clustering of individuals with similar psychosocial constructs. In addition, colorectal cancer screening rates and changes in psychosocial scores between the latent groups were compared.Three psychosocial profiles, including a low benefit and high susceptibility group (LBHS), a high benefit and low susceptibility group (HBLS), and a high barrier and high susceptibility group (HBHS), were identified in this study. The HBLS group had the lowest susceptibility, with no improvement in benefits and barriers. This group had the lowest screening rate (80.85%) compared with 88.8% in LBHS and 86.3% in HBHS following the intervention. Finally, the intervention effect size on psychosocial score changes was smaller in HBLS than in other groups.This subgroup analysis suggests that colorectal cancer educational interventions should be tailored to improve the benefits and barriers among individuals with high susceptibility scores.

PREVENTION RELEVANCE

This LPA analysis provides some direction for tailoring colorectal cancer educational interventions to improve the benefits and barriers among individuals with high susceptibility scores in hard-to-screen populations such as our border population.

Examining the continuum of resistance model in two population-based screening studies in Sweden

In studies recruited on a voluntary basis, lack of representativity may impair the ability to generalize findings to the target population. Previous studies, primarily based on surveys, have suggested that generalizability may be improved by exploiting data on individuals who agreed to participate only after receiving one or several reminders, as such individuals may be more similar to non-participants than what early participants are. Assessing this idea in the context of screenings, we compared sociodemographic characteristics and health across early, late, and non-participants in two large population-based screening studies in Sweden: STROKESTOP II (screening for atrial fibrillation; 6,867 participants) and SCREESCO (screening for colorectal cancer; 39,363 participants). We also explored the opportunities to reproduce the distributions of characteristics in the full invited populations, either by assuming that the non-participants were similar to the late participants, or by applying a linear extrapolation model based on both early and late participants. Findings showed that early and late participants exhibited similar characteristics along most dimensions, including civil status, education, income, and health examination results. Both these types of participants in turn differed from the non-participants, with fewer married, lower educational attainments, and lower incomes. Compared to early participants, late participants were more likely to be born outside of Sweden and to have comorbidities, with non-participants similar or even more so. The two empirical models improved representativity in some cases, but not always. Overall, we found mixed support that data on late participation may be useful for improving representativeness of screening studies.

[Severity, susceptibility and social norms perceived as antecedents of the intention to be vaccinated against COVID-19]

OBJECTIVE

To evaluate the effect of perceived risk and social norms on COVID-19 and on the intention to be vaccinated if a vaccine were available to prevent infection.

METHODS

A quantitative, explanatory and cross-sectional research was developed. The data was collected through a structured questionnaire applied electronically to inhabitants over 18 years of age in the state of Puebla in Mexico. An analysis with structural equations was used to identify the effects among the constructs studied.

RESULTS

The results showed that both the perceived severity and susceptibility of contracting COVID-19 had a positive effect on the perceived social norms about the virus. Also, while the perceived severity had a positive effect on the intention to vaccinate, the perceived susceptibility was not significant on the intention to vaccinate against COVID-19.

CONCLUSION

Intention to be vaccinated against COVID-19 is affected by the severity and perceived social norms of contracting the infection. However, the perceived susceptibility to the virus does not have an effect on the intention to be vaccinated.

The Influence of Message Framing on Elderly Tourists' Purchase Intentions of Health Services: A Case Study of Guangxi Bama

Traveling has become an increasingly important lifestyle for the elderly to realize active aging. The elderly are more inclined to pay attention to wellbeing-related products whilst on vacations, representing a market opportunity for providers of tourism health services. This study conducted an experiment to explore how message framing affects intentions to purchase health services in elderly tourists over the age of 59 years. A total of 216 elderly tourists from Bama, a famous wellness tourism destination in China, were recruited as participants for a single-factor (message framing: positive versus negative) experiment. Our results indicate the following: (1) message framing has a significant impact on elderly tourists' intentions to purchase health services. Compared with messages that are negatively framed, positive messages are more persuasive. (2) Perceived benefits mediate the above relationship. (3) Perceived susceptibility moderates the impact of message framing around perceived benefits, as well as the indirect effect of perceived benefits on purchase intention. Theoretically, this paper clarifies the mechanism and conditions of message framing in relation to its effects on consumer intentions, enriching knowledge about the intersection between tourism and health consumption. This paper also provides guidance for providers of health tourism who are seeking to capture the market of elderly tourists.

The Significant Predictors for Breast, Cervical, Colorectal, or Oral Cancer Screening Intention and Behavior in Taiwan

BACKGROUND

Cancer screening can improve outcomes in patients with cancer. Accordingly, under the direction of the National Health Insurance program, the Taiwan government conducts screenings for breast cancer, cervical cancer, oral cancer, and colorectal cancer.

OBJECTIVE

The aim of this study was to identify the primary predictors of cancer screening intention and behavior at 1 and 6 months after patients are provided information and an invitation by telephone to attend cancer screenings.

METHODS

In this prospective longitudinal study, 339 participants meeting the screening criteria were recruited. At baseline, telephone interviews were used to collect information on demographic characteristics, exercise and smoking habits, family cancer history, screening beliefs, and screening intention. Screening behavior was followed up at 1 and 6 months after the telephone interviews.

RESULTS

At baseline, 87.02% of the participants intended to undergo screening, and 31.86% and 63.42% had undergone screening after 1 and 6 months, respectively. The predictors of screening intention were awareness of the screening policy, willingness to learn about screening, and believing in the health benefits of screening. The predictor of screening behavior after 1 month was screening intention at baseline, and the predictors of behavior after 6 months were screening intention, marital status, and belief that cancer is a hereditary disease.

CONCLUSION

Adults with screening intention tended to undergo cancer screenings.

IMPLICATIONS FOR PRACTICE

The use of strategies based on screening intention, beliefs, and information can be used to improve participation in cancer screening in Taiwan.

COVID-19 complications and entrepreneurial intention among the entrepreneurs of Pakistan: evidence from the second wave of the pandemic

Purpose

At present, nearly the whole globe is facing a severe threat of COVID-19. This study aims to examine the COVID-19 complications and entrepreneurial intention among the entrepreneurs of Pakistan.

Design/methodology/approach

The study used a deductive approach. An online survey is conducted to collect cross-sectional data from entrepreneurs of Pakistan. Convenience sampling is applied to target the respondents. In total, 278 usable answers proceed for final analysis. The structural equation model (SEM) is used to infer the results.

Findings

The findings of the study highlight a significant negative effect of fear of COVID-19 (FO19), perceived susceptibility (PSU) and perceived severity (PSE) on entrepreneurial intention (EI) among the entrepreneurs.

Practical implications

The study would provide the guidelines for policymakers and planners to combat the barriers of fear, PSU and PSE during a pandemic. The findings of the second wave of COVID-19 may provide a warning to the government to take preventive measures to face the severe effect of the pandemic. Finally, the outcomes of the study may enrich the depth of COVID-19 literature globally.

Originality/value

This study is the first study highlighting factors such as fear, PSU and PSE toward EI in COVID-19 second wave.

Intention for Screening Colonoscopy among Previous Non-Participants: Results of a Representative Cross-Sectional Study in Germany

Early detection of colorectal cancer has the potential to reduce mortality at population level. Colonoscopy is the preferred modality for colon cancer screening and prevention, but attendance rates are low. To exploit colonoscopy's preventive potential, it is necessary to identify the factors influencing uptake, especially among previous non-participants. This analysis of cross-sectional data involved 936 non-participants in screening colonoscopy aged 55 years or older in Germany. Differences between non-participants with and without future participation intentions were investigated in terms of socio-demographic factors, health status, attitudes and beliefs, and medical counselling. Logistic regression models were fitted to estimate associations between intention to participate and selected factors. Intention to participate was lower among women than among men. For both genders, intention to participate was positively associated with younger age. For women, higher socioeconomic status and counselling were positively associated with intention to participate. Men showed a positive association with favouring joint decision-making. The results draw attention to starting points for improving acceptance of and participation in screening colonoscopy. This includes good medical counselling and successful physician-patient communication, for which the information and communication skills of both medical professions and the general public should be strengthened. Gender differences should be considered.

A Model-Based Meta-Analysis of Willingness to Participate in Cancer Screening

Although early screening tests are beneficial for the detection and treatment of cancers, many people have failed to participate in screening tests. The present study aims to explore the theoretical underpinning of low participation in screening programs using the method of meta-analytic structural equation modeling. It was found that the health belief model is the most adopted theoretical framework. Moreover, the intended uptake of screening was positively predicted only by cues to action, health literacy, and perceived susceptibility. As a result, a health intention model, including the three significant variables, is proposed. The practical implications of the findings are that health communication campaigns should focus on enlightening and engaging the public through all necessary means to raise awareness and transfer knowledge in relation to screening procedures as well as cancers per se.

Perceived susceptibility to developing cancer and screening for colorectal and prostate cancer: A longitudinal analysis of Alberta's Tomorrow Project

INTRODUCTION

To assess the association between perceived susceptibility of developing cancer and being screened via sigmoidoscopy/colonoscopy and prostate-specific antigen, respectively.

METHODS

Participants aged 35-69, who resided in Alberta, Canada, were enrolled into the study between 2000 and 2008. We used general linear mixed models, adjusted for age, marital status, work status, education, family history and place of residence, to explore the association.

RESULTS

Perceived susceptibility of developing cancer was associated with both screening tests at baseline and a maximum of 14-year follow-up: (i) colorectal cancer screening - adjusted odds ratios were 1.97 (95% CI = 1.52-2.55) per one-unit increase in participants' personal belief in susceptibility to cancer, and 1.03 (95% CI = 1.00-1.04) per one-percent increase in participants' estimate of their own chance of developing cancer; (ii) prostate cancer screening - adjusted odds ratios were 1.36 times greater (95% CI = 1.07-1.72), and 1.02 times higher (95% CI = 1.01-1.03), for each respective perceived susceptibility measure.

CONCLUSION

Health promotion can focus on targeting and heightening personal perceived susceptibility of developing cancer in jurisdictions with low screening rates for colorectal or prostate cancer.

Financial Incentives to Increase Colorectal Cancer Screening Uptake and Decrease Disparities: A Randomized Clinical Trial

Importance

Colorectal cancer screening rates are suboptimal, particularly among sociodemographically disadvantaged groups.

Objective

To 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 Participants

This 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.

Interventions

Interventions 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 Measures

The 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.

Results

A 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 Relevance

Financial incentives increased FIT uptake but not overall colorectal cancer screening. Financial incentives may decrease screening disparities among some sociodemographically disadvantaged groups.

A Predictive Model of Perceived Susceptibility during the Year before Coronary Artery Bypass Grafting

Background: Based on the protective health model, one of the most important components of etiological factors leading to protective health behaviors is perceived risk or perceived susceptibility. Accordingly, the present study was conducted to assess the uncontrolled and controlled effects of some factors in predicting perceived susceptibility among coronary artery bypass graft (CABG) patients.

Methods: The data for the present cross-sectional study were gathered via assessment of 1052 CABG patients who referred to an outpatient cardiac rehabilitation clinic in a hospital in Iran between 2010 and 2014. The patients completed a checklist containing demographics, risk factors, and a single closed-ended question regarding perceived susceptibility at the beginning of their rehabilitation program. Binary logistic regression analysis was applied to identify the demographic and clinical correlations related to perceived susceptibility.

Results: Totally, 776 (73.8%) of the 1052 participants were male. The mean age of the patients was 58.0 ± 9.1 years. The results revealed that only 13.7% of the patients had perceived susceptibility; in addition, higher age (p value = 0.003) and family history of cardiac diseases (p value = 0.001) were able to significantly predict perceived susceptibility. When the demographic variables were controlled, once again age and family history of cardiac diseases were able to significantly increase perceived susceptibility by approximately 1.04 and 29.6 times, respectively.

Conclusion: Our results revealed that higher age and family history of cardiac diseases were able to significantly predict perceived susceptibility among our CABG patients.

Predictors of colorectal cancer screening intention among Iranian adults: an application of the preventive health model

OBJECTIVE

Colorectal cancer (CRC) is the third most common cancer among adults in Iran. CRC screening is an effective way in reducing mortality rate from this cancer. However, the screening rate of CRC is very low among Iranian adults. This study investigated predictors of Iranian average-risk adults ' intention to take up CRC screening with fecal occult blood test using a mediator model.

METHODS

Participants of this cross-sectional study comprised of 477 average-risk adults who were selected using a national sampling frame in Hamadan city, west of Iran. Data was collected through the questionnaire based on the preventive health model constructs. Structural Equation Modeling (SEM) was employed to test the relationship using Smart PLS 2.0 software.

RESULTS

All measures were robust in terms of the reliability and validity. Benefit (b = 0.12, p < 0.01), self- efficacy (b = 0.36, p < 0.01), social support (b = 0.10, p < 0.05) and barriers (b = -0.14, p < 0.01) predicted the intention to be screened for CRC. Self- efficacy partly mediated the effects of social support and perceived barriers on intention. The study model explained approximately 24% of the variance in CRC screening intention with fecal occult blood test.

CONCLUSION

Our findings indicated that the preventive health model constructs such as self -efficacy, social support and barriers are useful in understanding CRC screening intentions and can help health planners to develop effective interventions to encourage Iranian adults to undergo CRC screening.

Routine colonoscopy, diabetic eye care, mammogram and pap smear screening in vascular surgery patients

Objective An increasing emphasis on preventive medicine has been supported by the recent reforms in United States health care system. Majority of the patients seen in vascular surgery clinics are elderly with more extensive medical comorbidities compared to the general population. Thus, these patients would be expected at higher risk for common malignant pathologies such as colon, breast and cervical cancer, and nonmalignant diseases such as diabetic retinopathy. This study looked at the screening compliance of vascular patients compared to data provided by Centers for Disease Control on the national and state levels. Methods The office records of 851 consecutive patients seen in Brooklyn and Staten Island vascular clinics were examined. We queried patients regarding their last colonoscopy, diabetic eye exams, recent mammograms, and Pap smears. Our patient screening compliance was compared between the two clinics as well as to the national and New York state data provided by Centers for Disease Control. Compliance with regard to patient's age was also examined. Results Patients referred to the Staten Island office have a better colonoscopy compliance compared to the Brooklyn office ( P = .0001) and the national Centers for Disease Control average ( P = .026). Compliance for mammography and cervical cancer screening was higher in Staten Island office compared to the Brooklyn office ( P = .0001, P < .0001), respectively. Compliance was lower for Pap smear ( P = .0273) in Brooklyn when compared to the national average. Compliance for colonoscopy increased with age for both clinics ( P = .001, P < .001), while Pap smear decreased ( P < .001, P = .004). Conclusion Patients in vascular clinics in an urban setting had better adherence to screening protocol than the national and state average, with the exception of female patients for colonoscopy in our Brooklyn vascular office. There exists variability in both patient populations based on sub-specific locality and demographics including socioeconomic status. Overall, however patients in Staten Island had better compliance and adherence to the screening protocol than Brooklyn vascular clinic.

Evaluation of the effect of an audit and feedback reporting tool on screening participation: The Primary Care Screening Activity Report (PCSAR)

Participation in cancer screening is critical to its effectiveness in reducing the burden of cancer. The Primary Care Screening Activity Report (PCSAR), an electronic report, was developed as an innovative audit and feedback tool to increase screening participation in Ontario's cancer screening programs. This study aims to assess its impact on patient screening participation. This study used a retrospective cohort design to evaluate the effectiveness of the 2014 PCSAR on screening participation in Ontario's three screening programs (breast, cervix and colorectal). The 3 cohorts comprised all participants eligible for each of the programs enrolled with a primary care physician in Ontario. Two exposures were evaluated for each cohort: enrollment with a physician who was registered to receive the PCSAR and enrollment with a registered physician who also logged into the PCSAR. Logistic regression modelling was used to assess the magnitude of the effect of PCSAR on participation, adjusting for participant and physician characteristics. Across all three screening programs, 63% of eligible physicians registered to receive the PCSAR and 38% of those registered logged-in to view it. Patients of physicians who registered were significantly more likely to participate in screening, with odds ratios ranging from 1.06 [1.04;1.09] to 1.15 [1.12;1.19]. The adjusted odds ratios associated with PCSAR log-in were 1.07 [1.03;1.12] to 1.18 [1.14;1.22] across all screening programs. Implementation of the PCSAR was associated with a small increase in screening participation. The PCSAR appears to be modestly effective in assisting primary care physicians in optimizing cancer screening participation among their patients.

Deliberative and intuitive risk perceptions as predictors of colorectal cancer screening over time

Cancer risk perceptions may involve intuitions-including both affect as well as gut-level thoughts about risk-and deliberative risk magnitudes. Yet, little research has examined the potentially diverse relations between risk perceptions and behavior across time. A highly diverse primary care sample (N = 544, aged ≥50) was utilized to compare how deliberative and intuitive perceptions of risk relate to chart-confirmed colorectal cancer screening at cross-sectional and prospective time points. At baseline, deliberative and intuitive risk perceptions were negatively associated with chart-confirmed colorectal cancer screening adherence in bivariable but not multivariable analyses. Among those who were non-adherent with colorectal cancer screening at baseline, deliberative and intuitive risk perceptions were positively associated with prospective uptake of chart-confirmed colorectal cancer screening adherence at 12-months in bivariable analyses; only deliberative risk perceptions remained significant in the multivariable model. This study indicates that diverse risk perceptions are differentially important for screening at different time points.

Changing organizational culture: using the CEO cancer gold standard policy initiatives to promote health and wellness at a school of public health

Background

Worksite wellness initiatives for health promotion and health education have demonstrated effectiveness in improving employee health and wellness. We examined the effects of a multifaceted health promotion campaign on organizational capacity to meet requirements to become CEO Cancer Gold Standard Accredited.

Methods

We conducted an online survey to assess perceived organizational values and support for the five CEO Cancer Gold Standard Pillars for cancer prevention: tobacco cessation; physical activity; nutrition; cancer screening and early detection; and accessing information on cancer clinical trials. Baseline and follow-up surveys were sent 6-months apart to faculty, staff, and students at a school of public health to test the impact of a multifaceted health promotion campaign on perceived organizational change. Descriptive analyses were used to characterize percent improvement. Multivariate logistic regression analyses were used to control for participants’ university status.

Results

The current organizational culture highly supported tobacco cessation at both time points. Significant improvements (p < .05) from baseline to follow-up were observed for questions measuring organizational values for ‘prevention, screening, and early detection of cancer’ and ‘accessing cancer treatment and clinical trials’.

Conclusions

Health promotion and education efforts using multiple approaches were effective to improve perceived organizational values and support for cancer prevention and early detection, and increase access to information about cancer clinical trials. Future studies are needed to examine broader impacts of implementing worksite health promotion initiatives.

Does colorectal cancer risk perception predict screening behavior? A systematic review and meta-analysis

Although health behavior theories postulate that risk perception should motivate colorectal cancer (CRC) screening, this relationship is unclear. This meta-analysis aims to examine the relationship between CRC risk perception and screening behavior, while considering potential moderators and study quality. A search of six databases yielded 58 studies (63 effect sizes) that quantitatively assessed the relationship between CRC risk perception and screening behavior. Most included effect sizes (75 %) reported a positive association between CRC risk perception and screening behavior. A random effects meta-analysis yielded an overall effect size of z = 0.13 (95 % CI 0.10-0.16), which was heterogeneous (I (2) = 99 %, τ(2) = 0.01). Effect sizes from high-quality studies were significantly lower than those from lower quality studies (z = 0.02 vs. 0.16). We found a small, positive relationship between CRC risk perception and reported screening behavior, with important identified heterogeneity across moderators. Future studies should focus on high quality study design.

Impact of a Multifaceted Intervention on Promoting Adherence to Screening Colonoscopy Among Persons in HIV Primary Care: A Pilot Study

HIV-positive patients have lower colon cancer screening rates and are at increased risk for colon adenocarcinoma. We tested a transdisciplinary prevention model to increase provider and patient adherence to screening colonoscopy. Of 1,339 HIV-positive patients with scheduled clinic appointments during the period September to November 2009, we identified 400 records of eligible patients ≥50 years and retrospectively reviewed for screening colonoscopy referral; if never referred, flagged for referral at next visit. Providers referred 43.5% (174/400) patients and 36.2% (63/174) kept appointment. Within 6 months before the study, 337 patients attended clinic and providers referred 18%. Note that 211/226 patients with flagged records attended clinic at least once during the study 6-month period and providers referred (43.6%). The referral rate for flagged records was significantly different from that for the prior 6 months (p < 0.0001). A randomized trial compared the efficacy of patient decision support versus usual care on screening adherence. Among patients randomized to intervention 17 (51.5%) compared to usual care only 16 (48.5%), intervention group showed significant adherence of 70.6% (12/17) versus 29.4% (5/16), (p = 0.024). In addition, intervention patients had good bowel preparation of 76.9% (10/13) versus usual care 23.1% (3/13), (p = 0.05). This transdisciplinary intervention model significantly increased provider and patient screening colonoscopy behavior.

Longitudinal predictors of colorectal cancer screening among participants in a randomized controlled trial

OBJECTIVE

Few studies use longitudinal data to identify predictors of colorectal cancer screening (CRCS). We examined predictors of (1) initial CRCS during the first year of a randomized trial, and (2) repeat CRCS during the second year of the trial among those that completed FOBT in Year 1.

METHODS

The sample comprised 1247 participants of the Systems of Support to Increase Colorectal Cancer Screening (SOS) Trial (Group Health Cooperative, August 2008 to November 2011). Potential predictors of CRCS were identified with logistic regression and included sociodemographics, health history, and validated scales of psychosocial constructs.

RESULTS

Prior CRCS (OR 2.64, 95% CI 1.99-3.52) and intervention group (Automated: OR 2.06 95% CI 1.43-2.95; Assisted: OR 4.03, 95% CI 2.69-6.03; Navigated: OR 5.64, 95% CI 3.74-8.49) were predictors of CRCS completion at Year 1. For repeat CRCS at Year 2, prior CRCS at baseline (OR 1.97, 95% CI 1.25-3.11), intervention group (Automated: OR 9.27, 95% CI 4.56-18.82; Assisted: OR 11.17, 95% CI 5.44-22.94; Navigated: OR 13.10, 95% CI 6.33-27.08), and self-efficacy (OR 1.32, 95% CI 1.00-1.73) were significant predictors.

CONCLUSION

Self-efficacy and prior CRCS are important predictors of future screening behavior. CRCS completion increased when access barriers were removed through interventions.

Exploring the validity of the continuum of resistance model for discriminating early from late and non-uptake of colorectal cancer screening: implications for the design of invitation and reminder letters

BACKGROUND

The continuum of resistance model contends that respondents lie at one end of a continuum and non-respondents at the other with respect to factors demonstrated to impact on screening participation.

PURPOSE

The aim of this study was to explore the validity of this model for the prediction of participation in colorectal cancer screening.

METHOD

People aged 50 to 74 years were asked to complete a survey (n = 1,250). Eligible respondents (n = 376, 30 %) were invited to complete a faecal occult blood test (FOBT). The cutoff period for the determination of participation rates was 12 weeks, with a reminder sent at 6 weeks.

RESULTS

FOBTs were returned by n = 196 people (132 within 6 weeks, 64 following a reminder). Participation was generally influenced by the same variables in both the first 6 weeks and the second 6 weeks, consistent with the continuum of resistance model. These variables were having known someone with bowel cancer and the social cognitive factor, perceptions of barriers to screening. There is a suggestion, however, that other factors may be differentially associated with early, late and non-participants.

CONCLUSION

Participation in screening appears somewhat consistent with the continuum of resistance model in that early and late participants respond to some of the same factors. This suggests that the same messages are relevant to early, late and non-screeners, but further consideration of what other factors may be influencing discrete stages of readiness to participate is necessary.

Exploration of risk taking behaviors and perceived susceptibility of colorectal cancer among Malaysian adults: a community based cross-sectional study

BACKGROUND

Perceived susceptibility to an illness has been shown to affect Health-risk behavior. The objective of the present study was to determine the risk taking behaviors and the demographic predictors of perceived susceptibility to colorectal cancer in a population-based sample.

METHODS

A cross-sectional study was carried out among 305 Malaysian adults in six major districts, selected from urban, semi-urban, and rural settings in one state in Malaysia. A self-administered questionnaire was used in this study. It was comprised of socio-demographics, risk-taking behaviors, and validated domains of the Health Belief Model (HBM).

RESULTS

The mean (± SD) age of the respondents was 34.5 (± 9.6) and the majority (59.0%) of them were 30 years or older. Almost 20.7% of the respondents felt they were susceptible to colorectal cancer. Self-reported perceived susceptibility mirrored unsatisfactory screening behaviors owing to the lack of doctors' recommendation, ignorance of screening modalities, procrastination, and the perception that screening was unnecessary. Factors significantly associated with perceived susceptibility to colorectal cancer were gender (OR = 1.8, 95% CI 1.0-3.3), age (OR = 2. 2, 95% CI 1.2-4.0), ethnicity (OR = 0. 3, 95% CI 0.2-0.6), family history of colorectal cancer (OR = 3. 2, 95% CI 1.4-7.4) and alcohol intake (OR = 3.9, 95% CI 2.1-7.5).

CONCLUSION

The present study revealed that screening behavior among respondents was unsatisfactory. Hence, awareness of the importance of screening to prevent colorectal cancers is imperative.

Perceived risk for breast cancer and its relationship to mammography in Blacks, Hispanics, and Whites

A challenge for health behavior science is to develop theory and best practices that take cultural diversity into account. Using data from Black, Hispanic, and White respondents to the 2003 Health Information National Trends Survey, we examined racial/ethnic differences in: (1) breast cancer risk perceptions/worry; (2) the associations between perceived risk/worry and ever having received a mammogram; and (3) perceived risk/worry and having had at least 2 mammograms over a 4-year period (consecutive mammography). Compared to White race/ethnicity, Black race/ethnicity was associated with lower perceived absolute risk and comparative risk for developing cancer. For the sample as a whole, higher perceived risk (both absolute risk and comparative risk) and worry predicted greater odds of mammography use; however, this was not true for Hispanics. In stratified analyses, perceived risk and worry were not associated with mammography use for either Hispanics or Blacks whereas they were for Whites; however, this interaction effect was significant only for Hispanics vs. Whites. Results support the need for formative research to identify determinants of health behavior prior to cancer prevention message planning for diverse audiences in order to accommodate racial/ethnic differences not only in the level of perceived risk, but also the association between risk perception to behavior change in that community.

Gender differences in predictors of colorectal cancer screening uptake: a national cross sectional study based on the health belief model

BACKGROUND

Colorectal Cancer (CRC) is rapidly rising in Asia, but screening uptake remains poor. Although studies have reported gender differences in screening rates, there have been few studies assessing gender specific perceptions and barriers towards CRC screening, based on behavioral frameworks. We applied the Health Belief Model to identify gender-specific predictors of CRC screening in an Asian population.

METHODS

A nationwide representative household survey was conducted on 2000 subjects aged 50 years and above in Singapore from 2007 to 2008. Screening behaviour, knowledge and beliefs on CRC screening were assessed by face-to-face structured interviews. The response rate was 88.2%.

RESULTS

26.7 percent had undergone current CRC screening with no gender difference in rates. Almost all agreed that CRC would lead to suffering (89.8%), death (84.6%) and would pose significant treatment cost and expense (83.1%). The majority (88.5%) agreed that screening aids early detection and cure but only 35.4% felt susceptible to CRC. Nearly three-quarters (74.3%) of the respondents recalled reading or hearing information on CRC in the print or broadcast media. However, only 22.6% were advised by their physicians to undergo screening. Significantly more women than men had feared a positive diagnosis, held embarrassment, pain and risk concerns about colonoscopy and had friends and family members who encouraged screening. On multivariate analysis, screening uptake showed a positive association with worry about contracting CRC and a physician's recommendation and a negative association with perceived pain about colonoscopy for both genders. For women only, screening was positively associated with having attended a public talk on CRC and having a family member with CRC, and was negatively associated with Malay race and perceived danger of colonoscopy.

CONCLUSIONS

CRC screening remains poor despite high levels of awareness of its benefits in this Asian population. Race, worry about contracting cancer, psychological barriers, and cues from the doctor and a public talk on CRC were associated with screening with gender specific differences. Strategies to increase CRC screening uptake should consider gender specific approaches to address psychological barriers and increase disease susceptibility through public health education and active promotion by physicians.

Adherence to cancer screening guidelines and predictors of improvement among participants in the Kansas State Employee Wellness Program

Introduction

Employee wellness programs (EWPs) have been used to implement worksite-based cancer prevention and control interventions. However, little is known about whether these programs result in improved adherence to cancer screening guidelines or how participants’ characteristics affect subsequent screening. This study was conducted to describe cancer screening behaviors among participants in a state EWP and identify factors associated with screening adherence among those who were initially nonadherent.

Methods

We identified employees and their dependents who completed health risk assessments (HRAs) as part of the Kansas state EWP in both 2008 and 2009. We examined baseline rates of adherence to cancer screening guidelines in 2008 and factors associated with adherence in 2009 among participants who were initially nonadherent.

Results

Of 53,095 eligible participants, 13,222 (25%) participated in the EWP in 2008 and 6,205 (12%) participated in both years. Among the multiyear participants, adherence was high at baseline to screening for breast (92.5%), cervical (91.8%), and colorectal cancer (72.7%). Of participants who were initially nonadherent in 2008, 52.4%, 41.3%, and 33.5%, respectively, became adherent in the following year to breast, cervical, and colorectal cancer screening. Suburban/urban residence and more frequent doctor visits predicted adherence to breast and colorectal cancer screening guidelines.

Conclusion

The effectiveness of EWPs for increasing cancer screening is limited by low HRA participation rates, high rates of adherence to screening at baseline, and failure of nonadherent participants to get screening. Improving overall adherence to cancer screening guidelines among employees will require efforts to increase HRA participation, stronger interventions for nonadherent participants, and better access to screening for rural employees.

Gender differences in attitudes impeding colorectal cancer screening

Background

Colorectal cancer screening (CRCS) is the only type of cancer screening where both genders reduce risks by similar proportions with identical procedures. It is an important context for examining gender differences in disease-prevention, as CRCS significantly reduces mortality via early detection and prevention. In efforts to increase screening adherence, there is increasing acknowledgment that obstructive attitudes prevent CRCS uptake. Precise identification of the gender differences in obstructive attitudes is necessary to improve uptake promotion. This study randomly sampled unscreened, screening - eligible individuals in Ontario, employing semi-structured interviews to elicit key differences in attitudinal obstructions towards colorectal cancer screening with the aim of deriving informative differences useful in planning promotions of screening uptake.

Methods

N = 81 participants (49 females, 32 males), 50 years and above, with no prior CRCS, were contacted via random-digit telephone dialing, and consented via phone-mail contact. Altogether, N = 4,459 calls were made to yield N = 85 participants (1.9% response rate) of which N = 4 participants did not complete interviews. All subjects were eligible for free-of-charge CRCS in Ontario, and each was classified, via standard interview by CRCS screening decision-stage. Telephone-based, semi-structured interviews (SSIs) were employed to investigate gender differences in CRCS attitudes, using questions focused on 5 attitudinal domains: 1) Screening experience at the time of interview; 2) Barriers to adherence; 3) Predictors of Adherence; 4) Pain-anxiety experiences related to CRCS; 5) Gender-specific experiences re: CRCS, addressing all three modalities accessible through Ontario’s program: a) fecal occult blood testing; b) flexible sigmoidoscopy; c) colonoscopy.

Results

Interview transcript analyses indicated divergent themes related to CRCS for each gender: 1) bodily intrusion, 2) perforation anxiety, and 3) embarrassment for females and; 1) avoidant procrastination with underlying fatalism, 2) unnecessary health care and 3) uncomfortable vulnerability for males. Respondents adopted similar attitudes towards fecal occult blood testing, flexible sigmoidoscopy and colonoscopy, and were comparable in decision stage across tests. Gender differences were neither closely tied to screening stage nor modality. Women had more consistent physician relationships, were more screening-knowledgeable and better able to articulate views on screening. Men reported less consistent physician relationships, were less knowledgeable and kept decision-making processes vague and emotionally distanced (i.e. at ‘arm’s length’).

Conclusions

Marked differences were observed in obstructive CRCS attitudes per gender. Females articulated reservations about CRCS-associated distress and males suppressed negative views while ambiguously procrastinating about the task of completing screening. Future interventions could seek to reduce CRCS-related stress (females) and address the need to overcome procrastination (males).

Decision Support and the Effectiveness of Web-based Delivery and Information Tailoring for Bowel Cancer Screening: An Exploratory Study

Background

Colorectal cancer (CRC) is the third most commonly diagnosed cancer in males and the second in females throughout the developed world. Population screening using fecal occult blood tests (FOBTs) facilitates early detection and greater chance of survival, but participation rates are low. We developed a Web-based decision tool to provide information tailored to an individual’s decision stage for CRC screening and attitude toward screening utilizing the Preventive Health Model (PHM) and Precaution Adoption Process Model (PAPM) as theoretical frameworks for screening behavior. We describe the practical steps employed in the tool’s design and the subsequent conduct of an exploratory study.

Objective

To design a decision tool for CRC screening and conduct an exploratory study among average-risk men and women to (1) test the impact of message type (tailored vs non-tailored) and message delivery modality (Web-based vs paper-based) on attitudes toward screening and screening uptake, and (2) investigate the acceptability of the decision tool and relevance of materials.

Methods

Participants (n = 100), recruited from a population sample of men and women aged 50-76 residing in urban Adelaide, Australia, were randomly assigned to a control group or one of 4 interventions: (1) Web-based and tailored information, (2) paper-based and tailored information, (3) Web-based and non-tailored (generic) information, or (4) paper-based and non-tailored information. Participation was augmented by snowball recruitment (n = 19). Questionnaires based on PHM variables were administered pre- and post-intervention. Participants were given the opportunity to request an FOBT. Following the intervention, participants discussed the acceptability of the tool.

Results

Full data were available for 87.4% (104/119) of participants. Post-intervention, perceived susceptibility scores for individuals receiving tailored information increased from mean 10.6 (SD 2.1) to mean 11.8 (SD 2.2). Scores on self-efficacy increased in the tailored group from mean 11.7 (SD 2.0) to mean 12.6 (SD 1.8). There were significant time x modality x message effects for social influence and salience and coherence, reflecting an increase in these scores for tailored Web-based participants only; social influence scores increased from mean 11.7 (SD 2.6) to mean 14.9 (SD 2.3), and salience and coherence scores increased from mean 16.0 (SD 2.2) to mean 17.7 (SD 2.1). There was no greater influence of modality or message type on movement toward a decision to screen or screening uptake, indicating that neither tailored messages nor a Web modality had superior effect. Overall, participants regarded tailored messages positively, but thought that the Web tool lacked “media richness.”

Conclusions

This exploratory study confirms that tailoring on PHM predictors of CRC screening has the potential to positively address attitudes toward screening. However, tailoring on these variables did not result in significantly increased screening uptake. Future research should consider other possible psychosocial influences. Mode of delivery did not affect outcomes, but as a delivery medium, the Web has economic and logistical advantages over paper.

Using the interdependence model to understand spousal influence on colorectal cancer screening intentions: a structural equation model

BACKGROUND

Although it is widely thought that the marital relationship plays a role in individuals' decisions to have colorectal cancer screening, few studies have evaluated partner influences.

PURPOSE

We evaluated the role of marital relationship factors such as a relational perspective on the frequency of spouse discussions about screening and screening intentions. Individual-level factors were also evaluated.

METHODS

One hundred sixty-eight couples with both members non-adherent with screening completed measures of perceived risk, screening benefits and barriers, marital quality, relational perspective, discussion frequency, and screening intentions.

RESULTS

Couples' attitudes about screening were interdependent and one partner's attitudes and behavior were associated with the other partner's intention. There was also evidence of joint effects in that intentions were associated with both one's partner's attitudes and one's own attitudes.

CONCLUSIONS

Colorectal screening intentions are associated with both partners' attitudes as well as whether or not couples have discussed screening with one another.

Colorectal cancer screening knowledge, attitudes and behavioural intention among Indigenous Western Australians

Background

Indigenous Australians are significantly less likely to participate in colorectal cancer (CRC) screening compared to non-Indigenous people. This study aimed to identify important factors influencing the decision to undertake screening using Faecal Occult Blood Testing (FOBT) among Indigenous Australians. Very little evidence exists to guide interventions and programmatic approaches for facilitating screening uptake in this population in order to reduce the disparity in colorectal cancer outcomes.

Methods

Interviewer-administered surveys were carried out with a convenience sample (n = 93) of Indigenous Western Australians between November 2009-March 2010 to assess knowledge, awareness, attitudes and behavioural intent in regard to CRC and CRC screening.

Results

Awareness and knowledge of CRC and screening were low, although both were significantly associated with exposure to media advertising (p = 0.008; p < 0.0001). Nearly two-thirds (63%; 58/92) of respondents reported intending to participate in screening, while a greater proportion (84%; 77/92) said they would participate on a doctor’s recommendation. Multivariate analysis with logistic regression demonstrated that independent predictors of screening intention were, greater perceived self-efficacy (OR = 19.8, 95% CI = 5.5-71.8), a history of cancer screening participation (OR = 6.8, 95% CI = 2.0-23.3) and being aged 45 years or more (OR = 4.5, 95% CI = 1.2-16.5). A higher CRC knowledge score (medium vs. low: OR = 9.9, 95% CI = 2.4-41.3; high vs. low: 13.6, 95% CI = 3.4-54.0) and being married or in a de-facto relationship (OR = 6.9, 95% CI = 2.1-22.5) were also identified as predictors of intention to screen with FOBT.

Conclusions

Improving CRC related knowledge and confidence to carry out the FOBT self-screening test through education and greater promotion of screening has the potential to enhance Indigenous participation in CRC screening. These findings should guide the development of interventions to encourage screening uptake and reduce bowel cancer related deaths among Indigenous Australians.

Cultural, economic, and psychological predictors of colonoscopy in a national sample

BACKGROUND

Although colorectal cancer (CRC) is the second leading cause of cancer death among adults in the US and colonoscopy is efficacious in reducing morbidity and mortality from CRC, screening rates are sub-optimal. Understanding the socioeconomic, cultural, and health care context within which decisions about colonoscopy are made allows physicians to address patients' most salient beliefs and values and other constraints when making screening recommendations.

OBJECTIVE

To evaluate the direct and interactive effects of socioeconomics, health care variables, psychological characteristics, and cultural values on colonoscopy use.

DESIGN, SETTING, PARTICIPANTS

National survey completed between January-August 2009 in a random sample of African American, white, and Hispanic adults ages 50-75 without cancer (n = 582).

MAIN MEASURE

Self-reported colonoscopy use.

KEY RESULTS

Only 59% of respondents reported having a colonoscopy. The likelihood of colonoscopy increased with having health insurance (OR = 2.82, 95% CI = 1.24, 6.43, p = 0.004), and increasing age (OR = 1.40, 95% CI = 1.11, 1.77, p = 0.001). In addition, respondents with greater self-efficacy were more likely to have a colonoscopy (OR = 2.41, 95% CI = 1.35, 4.29, p = 0.003).

CONCLUSIONS

Programs that help patients to overcome access and psychological barriers to screening are needed.

Understanding narrative effects: the impact of breast cancer survivor stories on message processing, attitudes, and beliefs among African American women

OBJECTIVE

Examine the longitudinal effects of personal narratives about mammography and breast cancer compared with a traditional informational approach.

METHODS

African American women (n = 489) ages 40 and older were recruited from low-income neighborhoods in St. Louis, Missouri, and randomized to watch a narrative video comprised of stories from African American breast cancer survivors or a content-equivalent informational video. Effects were measured immediately postexposure (T2) and at 3- (T3) and 6-month (T4) follow-up. T2 measures of initial reaction included positive and negative affect, trust, identification, and engagement. T3 message-processing variables included arguing against the messages (counterarguing) and talking to family members about the information (cognitive rehearsal). T4 behavioral correlates included perceived breast cancer risk, cancer fear, cancer fatalism, perceived barriers to mammography, and recall of core messages. Structural equation modeling examined interrelations among constructs.

RESULTS

Women who watched the narrative video (n = 244) compared to the informational video (n = 245) experienced more positive and negative affect, identified more with the message source, and were more engaged with the video. Narratives, negative affect, identification, and engagement influenced counterarguing, which, in turn, influenced perceived barriers and cancer fatalism. More engaged women talked with family members more, which increased message recall. Narratives also increased risk perceptions and fear via increased negative affect.

CONCLUSIONS

Narratives produced stronger cognitive and affective responses immediately, which, in turn, influenced message processing and behavioral correlates. Narratives reduced counterarguing and increased cognitive rehearsal, which may increase acceptance and motivation to act on health information in populations most adversely affected by cancer disparities.
