Project description:BackgroundCancer screening programmes in England are publicly-funded. Professionals' beliefs in the public health benefits of screening can conflict with individuals' entitlements to exercise informed judgement over whether or not to participate. The recognition of the importance of individual autonomy in decision making requires greater understanding of the knowledge, attitudes and beliefs upon which people's screening choices are founded. Until recently, the technology available required that cancer screening be confined to women. This study aimed to discover whether male and female perceptions of cancer and of screening differed.MethodsData on the public's cancer beliefs were collected by means of a postal survey (anonymous questionnaire). Two general practices based in Nottingham and in Mansfield, in east-central England, sent questionnaires to registered patients aged 30 to 70 years. 1,808 completed questionnaires were returned for analysis, 56.5 per cent from women.ResultsWomen were less likely to underestimate overall cancer incidence, although each sex was more likely to cite a sex-specific cancer as being amongst the most common cancer site. In terms of risk factors, men were most uncertain about the role of stress and sexually-transmitted diseases, whereas women were more likely to rate excessive alcohol and family history as major risk factors. The majority of respondents believed the public health care system should provide cancer screening, but significantly more women than men reported having benefiting from the nationally-provided screening services. Those who were older, in better health or had longer periods of formal education were less worried about cancer than those who had illness experiences, lower incomes, or who were smokers. Actual or potential participation in bowel screening was higher amongst those who believed bowel cancer to be common and amongst men, despite women having more substantial worries about cancer than men.ConclusionOur results suggest that men's and women's differential knowledge of cancer correlates with women's closer involvement with screening. Even so, men were neither less positive about screening nor less likely to express a willingness to participate in relevant screening in the future. It is important to understand gender-related differences in knowledge and perceptions of cancer, if health promotion resources are to be allocated efficiently.

Project description:BackgroundColorectal cancer is a leading cause of cancer mortality, yet effective screening tests are often underused. Electronic patient messages and personalized risk assessments delivered via an electronic personal health record could increase screening rates.MethodsWe conducted a randomized controlled trial in 14 ambulatory health centers involving 1103 patients ranging in age from 50 to 75 years with an active electronic personal health record who were overdue for colorectal cancer screening. Patients were randomly assigned to receive a single electronic message highlighting overdue screening status with a link to a Web-based tool to assess their personal risk of colorectal cancer. The outcomes included colorectal cancer screening rates at 1 and 4 months.ResultsScreening rates were higher at 1 month for patients who received electronic messages than for those who did not (8.3% vs 0.2%, P < .001), but this difference was no longer significant at 4 months (15.8% vs 13.1%, P = .18). Of 552 patients randomized to receive the intervention, 296 (54%) viewed the message, and 47 (9%) used the Web-based risk assessment tool. Among 296 intervention patients who viewed the electronic message, risk tool users were more likely than nonusers to request screening examinations (17% vs 4%, P = .04) and to be screened (30% vs 15%, P = .06). One-fifth of patients (19%) using the risk assessment tool were estimated to have an above-average risk for colorectal cancer.ConclusionElectronic messages to patients produce an initial increase in colorectal cancer screening rates, but this effect is not sustained over time.Trial registrationclinicaltrials.gov Identifier: NCT01032746.

Project description:INTRODUCTION:Appreciating the accuracy and value of cancer screening is essential to informed decision making about screening. This study's objectives were to (1) examine people's beliefs about the accuracy and value of cancer screening, and (2) determine whether sociodemographics, cancer beliefs, and shared decision making are associated with these beliefs. METHODS:Data from the National Cancer Institute's Health Information National Trends Survey (cycle 4, August-November 2014) were used. Respondents were non-institutionalized adults (aged ?18 years, n=3,677). Weighted generalized linear modeling was used to examine bivariate and multivariate associations between key covariates and beliefs about cancer screening (assessed by four-item scale and independently). Secondary analyses examined whether these beliefs were associated with self-reported cancer screening. Data were analyzed between 2016 and 2017. RESULTS:Only 5.6% (n=189) of respondents answered all four cancer screening items correctly. Men, racial/ethnic minorities, and those with lower education and higher cancer fatalism were less likely to have accurate beliefs about cancer screening. However, those who reported shared decision making for colorectal cancer screening were more likely to know that "when a test finds something abnormal, more tests are needed to know if it is cancer" and "when a test finds something abnormal, it is [not] very likely to be cancer" (adjusted risk ratio=1.13, p<0.01, adjusted risk ratio=1.25, p<0.01). Beliefs were not associated with likelihood of past mammography or Pap testing. CONCLUSIONS:Educators, researchers, and clinicians should consider opportunities (e.g., through shared decision making) to improve the accuracy of individuals' beliefs about cancer screening.

Project description:BackgroundLung cancer (LC) is the leading cause of cancer-related death for veterans cared for by the US Veterans Health Administration. The LC burden among veterans is almost double that of the general population. Before implementation of an LC screening program, we set out to assess the role of beliefs and attitudes toward LC screening among veterans.MethodsVeterans presenting to the Ralph H. Johnson VA Medical Center were invited to complete a self-administered survey. The survey comprised questions about demographics, smoking status, health status, and knowledge about LC and willingness to be screened. Responses from veteran ever and never smokers were compared.ResultsA total of 209 veterans completed the survey. Smokers were significantly (P < .05) more likely than never smokers to be less educated, have a lower income, and report poorer health. Smokers were more likely than never smokers to have two or more comorbidities, which trended toward significance (P = .062). Smokers were more likely to have been told by a physician that they were at high risk for LC and to believe that they were at risk. Nearly all veterans surveyed (92.8%) would have a CT scan for LC screening, and 92.4% would have surgery for a screen-detected LC.ConclusionsVeterans are overwhelmingly willing to undergo screening for LC, and it seems that participation will not be a barrier to implementation of an LC screening program. The mortality benefit of LC screening, however, may not be generalizable to the veteran population because of a higher number of comorbid conditions.

Project description:BackgroundLung cancer screening, despite its proven mortality benefit, remains vastly underutilized. Previous studies examined knowledge, attitudes, and beliefs to better understand the reasons underlying the low screening rates. These investigations may have limited generalizability because of traditional participant recruitment strategies and examining only subpopulations eligible for screening. The current study used crowdsourcing to recruit a broader population to assess these factors in a potentially more general population.MethodsA 31-item survey was developed to assess knowledge, attitudes, and beliefs regarding screening among individuals considered high risk for lung cancer by the United States Preventive Services Task Force. Amazon's crowdsourcing platform (Mechanical Turk) was used to recruit subjects.ResultsAmong the 240 respondents who qualified for the study, 106 (44%) reported knowledge of a screening test for lung cancer. However, only 36 (35%) correctly identified low-dose CT scanning as the appropriate test. A total of 222 respondents (93%) reported believing that early detection of lung cancer has the potential to save lives, and 165 (69%) were willing to undergo lung cancer screening if it was recommended by their physician. Multivariable regression analysis found that knowledge of lung cancer screening, smoking status, chronic pulmonary disease, and belief in the efficacy of early detection of lung cancer were associated with willingness to screen.ConclusionsAlthough a minority of individuals at high risk for lung cancer are aware of screening, the majority believe that early detection saves lives and would pursue screening if recommended by their primary care physician. Health systems may increase screening rates by improving patient and physician awareness of lung cancer screening.

Project description:The Breast Cancer Screening Beliefs Questionnaire (BCSBQ) has been designed as a culturally appropriate instrument for assessing women's beliefs, knowledge and attitudes to breast cancer and breast cancer screening practices. While it has proved to be a reliable instrument when applied to women of Chinese, Arabic and Korean origin living in Australia, its psychometric properties among women from African backgrounds have not been tested. The aim of this study is to examine the psychometric properties of the BCSBQ among African Australian women.The BCSBQ was administered to 284 African Australian women who were recruited from a number of African community organizations and churches. Factor analysis was conducted to study the factor structure. Construct validity was examined using Cuzick's non-parametric test while Cronbach alpha was used to assess internal consistency reliability.Exploratory factor analysis results demonstrated that the African-Australian BCSBQ can be conceptualized as a 4-factor model. The third factor, viz. "barriers to mammography", was split into two separate factors namely, "psychological" and "practical" barriers. The results indicated that the African-Australian BCSBQ had both satisfactory validity and internal consistency. The Cronbach's alpha of the three subscales ranged between 0.84-0.92. The frequency of breast cancer screening practices (breast awareness, clinical breast-examination and mammography) were significantly associated with attitudes towards general health check-ups and perceived barriers to mammographic screening.Our study provided evidence to support the psychometric properties of the BCSBQ.in African Australian women. The study moreover demonstrated that the use of the instrument can help health professionals to understand the beliefs, knowledge and attitudes to breast cancer among African Australian women and also the factors that impact on their breast cancer screening practices.

Project description:Using an online survey experiment with a national sample, this study examined how changing the type and valence of efficacy information in news stories discussing global climate change may impact intended political participation through the mediators of perceived internal, external, and response efficacy. Overall, the results revealed that after a single exposure to a news story, stories including positive internal efficacy content increased perceived internal efficacy, while stories including negative external efficacy content lowered perceived external efficacy. There were limited impacts of other types of efficacy content on perceived efficacy. Perceived internal, external, and response efficacy all offered unique, positive associations with intentions to engage in climate change-related political participation. The results suggest that news stories including positive internal efficacy information in particular have the potential to increase public engagement around climate change. The implications for science communication are discussed.

Project description:The US Preventive Services Task Force recommends that smokers aged 55-80 should be screened annually with low-dose computed tomography (LDCT). This study identified demographics, smoking history, health risk perceptions, knowledge, and attitudes factors of older smokers (≥55 years) related to LDCT agreement. Using binary logistic regression, a predictive model of factors to explain LDCT agreement was produced. This is a cross-sectional, national, online survey of 338 older smokers (≥55 years) with a ≥30 pack-year smoking history. Over 82% of the sample believed that a person who continues to smoke after the age of 40 has at least a 25% chance of developing lung cancer and 77.3% would "agree to a LDCT today". Using chi-square analyses, six variables that were significant at the 0.10 level were selected for inclusion in model development. Four of the independent variables made a unique statistically significant contribution to the model: perceives accuracy of the LDCT as an important factor in the decision to have a LDCT scan; believes that early detection of LC will result in a good prognosis; believes that they are at high risk for lung cancer; and is not afraid of CT scans. Of note, only 10.9% believed that a negative CT scan result would mean that they could continue to smoke. Older smokers are aware of the risks of smoking, are interested in smoking cessation, and most are interested in and positive about LDCT. Cognitive aspects of participation in screening are key to increasing the uptake of lung cancer screening among high-risk smokers.

Project description:BackgroundStudies have shown that presenting correct information about group norms to correct misperceptions of norms can influence health behaviours. In two online studies we investigated how different ways of communicating the current uptake of 43% of the English Bowel Scope Screening (BSS) programme affects intention among disinclined men and women.MethodsIn the first study, 202 participants were asked to interpret eight quantifiers for 43% uptake ('few', 'many', 'a considerable number', 'a large number', 'a great number', 'a lot', 'numerous' and 'nearly half') and to indicate how misleading they perceived each of them to be. In the second study, with 1245 participants, we compared the motivational impact of two quantifiers ('a large number' and 'nearly half' which were associated with the highest perceived uptake (48.9%) and considered least misleading in study 1 respectively) with a control message that did not contain any information on uptake, and a message which communicated actual uptake as a proportion (43%).ResultsWhile we found that both verbal quantifiers increased screening intentions compared with the control group (from 7.8 to 12.5%, aOR 1.72; 95%CI 1.00-2.96 in the case of 'a large number' and 14.3%, aOR 2.02; 95%CI 1.20-3.38 for 'nearly half'), simply communicating that 43% do the test, however, had no impact on intentions (9.9% vs. 7.8% aOR 1.25; 95%CI 0.73-2.16).ConclusionVerbal quantifiers can be used to improve the perception of low uptake figures and avoid a demotivating effect.

Project description:ObjectiveTobacco butts are the most littered item worldwide and pose a critical environmental and public health hazard. Given the positive impact of required graphic warnings on smoking, we sought to assess the impact of a policy requiring cigarette pack anti-littering messages on smokers' littering intentions.MethodsWe randomly assigned US adult smokers (n = 719) to receive labels on the side of their cigarette packs for three weeks: anti-littering messages or messages about chemicals in cigarette smoke.ResultsAnti-littering messages elicited higher intentions to refrain from littering in the next month compared to chemical messages (p < .05). Anti-littering messages also led to increased knowledge about cigarette butts being the most common form of litter, the number of conversations about littering, and thinking about the proper disposal of cigarettes (all p < .05). Finally, smoking from packs labeled with anti-littering messages led to fewer weeks littering from car windows compared to packs labeled with chemical messages (p < .05), but did not affect completely refraining from littering cigarette butts. Mediators of the messages' impact on littering intentions were thinking about proper cigarette butt disposal and perceived message effectiveness (both p < .05).ConclusionsPolicies requiring anti-littering messages on cigarette packs would raise awareness about the problem of cigarette butt litter and bolster intentions to not litter.
