Examining intuitive risk perceptions for cancer in diverse populations

Reasons people avoid colorectal cancer information: a mixed-methods study

OBJECTIVE

With screening, colorectal cancer can be detected when treatable, or even prevented. However, approximately one in five people tend to avoid colorectal cancer information, and avoidance is associated with being less likely to have been screened for the disease. Crucial to developing strategies to reduce information avoidance, we sought a comprehensive understanding of reasons people avoid colorectal cancer information.

METHODS AND MEASURES

In a mixed methods study, we surveyed 200 participants who varied with respect to avoidance and interviewed 15 people who tended to avoid colorectal cancer information (all aged 40-75) about reasons for avoiding.

RESULTS

In both survey and interviews, primary reasons for information avoidance were: (1) shielding from anxiety and other aversive emotion, (2) perceived information sufficiency and (3) feelings of information overload. Trait anxiety, fear of diagnosis, anticipating negative interactions with healthcare, and negative associations with screening procedures exacerbated avoidance. Participants justified information non-relevance by attributing risk to other people's characteristics such as family history, gastrointestinal symptoms, being male, or living an unhealthy lifestyle.

CONCLUSION

Novel findings include the triggering influence of trait anxiety and financial constraints on information avoidance. Also, information overload and incorrect understanding of risk factors may exacerbate perceptions of information sufficiency and avoidance.

Effect of Superstitious Beliefs and Risk Intuitions on Genetic Test Decisions

INTRODUCTION

Moving beyond numeric representations of risk perceptions, we examine cognitive causation, or superstitious thinking, and negative affect in risk as predictors of MC1R (i.e., moderate v. high risk) skin cancer genetic testing and responses to this testing.

METHODS

Participants (N = 496) completed baseline assessments using validated measures of cognitive causation (beliefs that thinking about cancer risk increases cancer likelihood) and negative affect in risk (negative feelings generated during risk perception) and subsequently received a test offer. Participants could access a website to learn about and request genetic testing. Those who tested (n = 167) completed assessments of cognitive and affective reactions 2 wk after testing, including the Impact of Events-Revised Intrusive thoughts subscale.

RESULTS

Those with higher negative affect in risk were less likely to return a saliva sample for testing (odds ratio = 0.98, 95% confidence interval = 0.96-0.99). Those with higher cognitive causation reported more fear (b = 0.28-0.31; P's < 0.05). Higher negative affect in risk was associated with more emotion-laden test responses, particularly in those receiving higher-risk as compared with average-risk results.

CONCLUSION

Negative affect in risk did not hamper test information seeking, although it did inhibit the uptake of genetic testing. Those with higher cognitive causation showed more fear regarding their test result, as indicated by higher distress in those who received average-risk results and lower believability in those who received higher-risk results.

Latinx Immigrant Mothers' Perceived Self-Efficacy and Intentions Regarding Human Papillomavirus Vaccination of Their Daughters

OBJECTIVE

Racial and ethnic disparities persist in cervical cancer cases, 90% of which are caused by the human papillomavirus (HPV). Suboptimal vaccine uptake is problematic, particularly among Latinx women, who have the highest cervical cancer incidence compared with other racial/ethnic groups. We examined the association of self-efficacy and HPV vaccination intention among Latinx immigrant mothers of unvaccinated 9- to 12-year-old girls.

METHODS

An interview-administered survey assessed baseline sociodemographic information, knowledge and perceived risk of cervical cancer and HPV, self-efficacy, and intention to vaccinate among 313 Latinx immigrant mothers in Alabama from 2013 to 2017 before the implementation of an intervention to promote HPV vaccination.

RESULTS

Participants were, on average, 35 years old, with 9 years of education, and had lived in the United States for 12 years. Mothers who perceived their daughters were at risk of HPV infection were more likely to be vaccine intent than their hesitant counterparts (p < .001). Vaccine hesitancy was more common in those with lower education, low HPV and cervical cancer knowledge, and lower perceived self-efficacy scores (p < .001). Self-efficacy was associated with vaccine intention when controlling for other variables (p < .001). The only variable associated with self-efficacy was HPV awareness (p = .001).

CONCLUSIONS

Programs promoting HPV vaccination among Latinx immigrants should include educational components regarding risks of HPV infection and cervical cancers in addition to information regarding access to vaccination services. Knowledge of risks and access may heighten perceptions of self-efficacy and improve vaccine uptake among this population.

Health Literacy, Education, and Internal Consistency of Psychological Scales

Background:

Measurement error might lead to biased estimates, causing ineffective interventions and service delivery. Identifying measurement error of health-related instruments helps develop accurate assessment of health-related constructs.

Objective:

We compared the internal consistency of eight psychological scales used in health research in groups with adequate versus limited health literacy and in groups with higher versus lower education.

Methods:

Participants (N = 1,005) from a nationally representative internet panel completed eight self-report scales: (1) information avoidance, (2) cognitive causation, (3) unpredictability, (4) perceived severity, (5) time orientation, (6) internal health locus of control, (7) need for cognition, and (8) social desirability. The first four assess beliefs about diabetes and colon cancer. We used the Newest Vital Sign to categorize participants' health literacy (limited vs. adequate). We also categorized participants' education (high school or less vs. more than high school). We compared the Cronbach's alpha for each psychological scale between groups with different health literacy and education levels using the Feldt test.

Key Results:

Among all the 13 subscales, scale internal consistency was significantly lower among people with limited health literacy than those with adequate health literacy for five subscales: information avoidance for colon cancer (0.80 vs. 0.88), unpredictability of diabetes (0.84 vs. 0.88), perceived severity for diabetes (0.66 vs. 0.75), need for cognition (0.63 vs. 0.82), and social desirability (0.52 vs. 0.68). Internal consistency was significantly lower among people who had a high school education or less than among those with more than a high school education for four scales: perceived severity of diabetes (0.70 vs. 0.75), present orientation (0.60 vs. 0.66), need for cognition (0.73 vs. 0.80), and social desirability (0.61 vs. 0.70).

Conclusions:

Several psychological instruments demonstrated significantly lower internal consistency when used in a sample with limited health literacy or education. To advance health disparities research, we need to develop new scales with alternative conceptualizations of the constructs to produce a measure that is reliable among multiple populations. [HLRP: Health Literacy Research and Practice. 2021;5(3):e244–e255.]

Plain Language Summary:

We compared the internal consistency of several psychological scales in groups with adequate versus limited health literacy and higher versus lower education. For several scales, internal consistency was significantly lower among (1) people with limited health literacy compared those who have adequate health literacy and/or (2) people who had a high school education or less compared to those with more than a high school education.

Priority of Risk (But Not Perceived Magnitude of Risk) Predicts Improved Sun-Protection Behavior Following Genetic Counseling for Familial Melanoma

BACKGROUND

Understanding multiple components of risk perceptions is important because perceived risk predicts engagement in prevention behaviors.

PURPOSE

To examine how multiple components of risk perceptions (perceived magnitude of and worry about risk, prioritization of the management of one's risk) changed following genetic counseling with or without test reporting, and to examine which of these components prospectively predicted improvements in sun-protection behavior 1 year later.

METHODS

A prospective, nonrandomized study design was used. Participants were 114 unaffected members of melanoma-prone families who (i) underwent genetic testing for a CDKN2A/p16 mutation (n = 69) or (ii) were at comparably elevated risk based on family history and underwent genetic counseling but not testing (no-test controls, n = 45). Participants reported risk perception components and sun-protection behavior at baseline, immediately following counseling, and 1 month and 1 year after counseling.

RESULTS

Factor analysis indicated three risk components. Carriers reported increased perceived magnitude and priority of risk, but not cancer worry. No-test controls showed no changes in any risk perception. Among noncarriers, priority of risk remained high at all assessments, whereas magnitude of risk and cancer worry decreased. Of the three risk components, greater priority of risk uniquely predicted improved self-reported sun protection 1 year post-counseling.

CONCLUSIONS

Priority of risk (i) seems to be a component of risk perceptions distinguishable from magnitude of risk and cancer worry, (ii) may be an important predictor of daily prevention behavior, and (iii) remained elevated 1 year following genetic counseling only for participants who received a positive melanoma genetic test result.

Examining strategies for addressing high levels of 'I don't know' responding to risk perception questions for colorectal cancer and diabetes: an experimental investigation

OBJECTIVE

Many people say they 'don't know' their risk for common diseases (DK responders). Inadequate health literacy and higher disease information avoidance may suppress risk knowledge and thereby increase DK responding. Study goals were to examine two plausible interventions to address the health education needs of DK responders. Design: Participants were identified in a pre-screener as DK responders for either diabetes or colorectal cancer (CRC) risk perception questions (N = 1276; 35% non-white; 49% inadequate health literacy). They were randomly assigned to read either standard or low literacy risk information about diabetes or CRC, and to undergo a self-affirmation intervention or not. Main outcome measure: DK responding following reading the risk information. Results: Neither intervention reduced DK responding. Multivariable analyses showed that health literacy, information avoidance and believing the disease is unpredictable - but not risk factor knowledge and need for cognition - best predicted participants' conversion from a DK response to a non-DK scale point response. Conclusion: Results confirm that both inadequate health literacy and higher information avoidance are associated with DK responding. DK responders are also disproportionately underserved and less adherent to health behaviors. Because galvanising risk perceptions are central to public health, addressing their information needs is a priority.

Lay beliefs about risk: relation to risk behaviors and to probabilistic risk perceptions

Lay illness risk beliefs are commonly held philosophies about how risk works. These include beliefs that one's personal illness risk is unknowable and beliefs that thinking about one's risk can actually increase that risk. Beliefs about risk may impact risk behaviors and thereby subsequent health status. However, limited research examines the relation between lay risk beliefs and health behavior. This paper explores this possible relation. A nationally representative sample of adults (N = 1005) recruited from an internet panel were surveyed about lay risk beliefs and risk perceptions regarding diabetes and colorectal cancer, psychosocial factors (i.e., health literacy, need for cognition, locus of control), demographics, and current health behaviors (i.e., cigarette smoking, red meat intake, physical activity). In separate sets of regressions controlling for either demographics, psychosocial factors, or risk perceptions, lay risk beliefs remained significantly related to health behaviors. It may be important to consider how to address lay risk beliefs in intervention content and targeting in order to increase adaptive health behaviors and thereby prevent chronic disease.

Using NCI-Designated Cancer Center Catchment-Area Data to Understand an Ignored but High-Need Constituent: People Uncertain or Avoidant about Their Cancer Risk

In 2016, the NCI provided supplemental funding to 15 NCI-designated cancer centers to enhance cancer centers' capacity to collect critical catchment-area data across behavioral and psychosocial domains [March 2019 issue of Cancer Epidemiology, Biomarkers & Prevention (CEBP)-CEBP Focus]. In response, we highlight opportunities for cancer risk perception research when collecting and utilizing catchment-area data given the remarkably high proportions of individuals who report they are at average cancer risk, high levels of cancer risk information avoidance, and extremely negative ("death") associations with cancer. First, we advocate for enhanced measurement specificity regarding whether some participants may be uncertain regarding their cancer risk. Second, we advocate for examination of whether the large proportion of people who rate their risk as average have common (demographic and attitudinal) characteristics, which may dictate specific and targeted cancer prevention and control intervention. Finally, we advocate for further examination of cancer risk information avoidance and negative cancer associations to clarify subgroups that may fail to engage with risk information. Given the ubiquity of risk uncertainty, information avoidance, and negative cancer associations, further research into these prevalent beliefs will enhance our ability to bring the latest information regarding cancer prevention and control to the general population of the United States.

Low Health Literacy and Health Information Avoidance but Not Satisficing Help Explain "Don't Know" Responses to Questions Assessing Perceived Risk

BACKGROUND

People who say they don't know (DK) their disease risk are less likely to engage in protective behavior.

PURPOSE

This study examined possible mechanisms underlying not knowing one's risk for common diseases.

METHODS

Participants were a nationally representative sample of 1005 members of a standing probability-based survey panel who answered questions about their comparative and absolute perceived risk for diabetes and colon cancer, health literacy, risk factor knowledge and health information avoidance, and beliefs about illness unpredictability. Survey satisficing was a composite assessment of not following survey instructions, nondifferentiation of responses, haphazard responding, and speeding. The primary outcomes were whether a person selected DK when asked absolute and comparative risk perception questions about diabetes or colon cancer. Base structural equation modeling path models with pathways from information avoidance and health literacy/knowledge to DK responding for each DK outcome were compared to models that also included pathways from satisficing or unpredictability beliefs.

RESULTS

Base models contained significant indirect effects of health literacy (odds ratios [ORs] = 0.94 to 0.97, all P < 0.02) and avoidance (ORs = 1.05 to 1.15, all P < 0.01) on DK responding through risk factor knowledge and a direct effect of avoidance (ORs = 1.21 to 1.28, all P < 0.02). Adding the direct effect for satisficing to models resulted in poor fit (for all outcomes, residual mean square error estimates >0.17, all weighted root mean square residuals >3.2, all Comparative Fit Index <0.47, all Tucker-Lewis Index <0.49), indicating that satisficing was not associated with DK responding. Unpredictability was associated with not knowing one's diabetes risk (OR = 1.01, P < 0.01).

LIMITATIONS

The data were cross-sectional; therefore, directionality of the pathways cannot be assumed.

CONCLUSIONS

DK responders may need more health information, but it needs to be delivered differently. Interventions might include targeting messages for lower health literacy audiences and disrupting defensive avoidance of threatening health information.

Lay Awareness of the Relationship between Age and Cancer Risk

BACKGROUND

Cross-sectional studies suggest many people are unaware that cancer risk increases with age, but this misbelief has rarely been studied prospectively, nor are its moderators known.

PURPOSE

To assess whether people recognize that cancer risk increases with age and whether beliefs differ according to gender, education, smoking status, and family history of cancer.

METHODS

First, items from the cross-sectional Health Information National Trends Survey (n = 2069) were analyzed to examine the association of age and perceived cancer risk. Second, the prospective National Survey of Midlife Development in the United States (n = 3896) was used to assess whether perceived cancer risk changes over a decade. Third, beliefs about the age at which cancer occurs were analyzed using the US Awareness and Beliefs about Cancer survey (n = 1080). As a comparator, perceived risk of heart disease was also examined.

RESULTS

Cross-sectionally, older age was associated with lower perceived cancer risk but higher perceived heart disease risk. Prospectively, perceived cancer risk remained stable, whereas perceived heart attack risk increased. Seventy percent of participants reported a belief that cancer is equally likely to affect people of any age. Across three surveys, women and former smokers/smokers who recently quit tended to misunderstand the relationship between age and cancer risk and also expressed relatively higher perceived cancer risk overall.

CONCLUSIONS

Data from three national surveys indicated that people are unaware that age is a risk factor for cancer. Moreover, those who were least aware perceived the highest risk of cancer regardless of age.

Implementing an Internet-Delivered Skin Cancer Genetic Testing Intervention to Improve Sun Protection Behavior in a Diverse Population: Protocol for a Randomized Controlled Trial

Background

Limited translational genomic research currently exists to guide the availability, comprehension, and appropriate use of personalized genomics in diverse general population subgroups. Melanoma skin cancers are preventable, curable, common in the general population, and disproportionately increasing in Hispanics.

Objective

Variants in the melanocortin-1 receptor (MC1R) gene are present in approximately 50% of the population, are major factors in determining sun sensitivity, and confer a 2-to-3-fold increase in melanoma risk in the general population, even in populations with darker skin. Therefore, feedback regarding MC1R risk status may raise risk awareness and protective behavior in the general population.

Methods

We are conducting a randomized controlled trial examining Internet presentation of the risks and benefits of personalized genomic testing for MC1R gene variants that are associated with increased melanoma risk. We will enroll a total of 885 participants (462 participants are currently enrolled), who will be randomized 6:1 to personalized genomic testing for melanoma risk versus waiting list control. Control participants will be offered testing after outcome assessments. Participants will be balanced across self-reported Hispanic versus non-Hispanic ethnicity (n=750 in personalized genomic testing for melanoma risk arm; n=135 in control arm), and will be recruited from a general population cohort in Albuquerque, New Mexico, which is subject to year-round sun exposure. Baseline surveys will be completed in-person with study staff and follow-up measures will be completed via telephone.

Results

Aim 1 of the trial will examine the personal utility of personalized genomic testing for melanoma risk in terms of short-term (3-month) sun protection and skin screening behaviors, family and physician communication, and melanoma threat and control beliefs (ie, putative mediators of behavior change). We will also examine potential unintended consequences of testing among those who receive average-risk personalized genomic testing for melanoma risk findings, and examine predictors of sun protection at 3 months as the outcome. These findings will be used to develop messages for groups that receive average-risk feedback. Aim 2 will compare rates of test consideration in Hispanics versus non-Hispanics, including consideration of testing pros and cons and registration of a decision to either accept or decline testing. Aim 3 will examine personalized genomic testing for melanoma risk feedback comprehension, recall, satisfaction, and cancer-related distress in those who undergo testing, and whether these outcomes differ by ethnicity (Hispanic vs non-Hispanic), or sociocultural or demographic factors. Final outcome data collection is anticipated to be complete by October 2017, at which point data analysis will commence.

Conclusions

This study has important implications for personalized genomics in the context of melanoma risk, and may be broadly applicable as a model for delivery of personalized genomic feedback for other health conditions.

Measurement invariance of intuitive cancer risk perceptions across diverse populations: The Cognitive Causation and Negative Affect in Risk scales

Intuitive cancer risk perceptions may inform strategies to motivate cancer prevention behaviors. This study evaluated factor structure and measurement invariance of two new measures of intuitive cancer risk, the Cognitive Causation and Negative Affect in Risk scales. Single- and multiple-group confirmatory factor analysis models were fit to responses from three diverse samples. The confirmatory factor analysis models fit the data well, with all comparative fit indices (CFI) ≥ 0.94. Items flagged by chi-square difference tests as potentially non-invariant were largely invariant between samples according to practical fit indices (e.g. ΔCFI). These novel scales may be particularly relevant in diverse, underserved populations.

Cancer beliefs and patient activation in a diverse, multilingual primary care sample

OBJECTIVES

Greater patient activation, defined as having the knowledge, skills, and confidence to manage one's health, is associated with cancer control behaviors. Cancer risk beliefs may be associated with patient activation, and delineating this relationship could inform cancer control interventions across diverse patient subgroups. This study examines associations between cancer risk beliefs, language preference, and patient activation within a multilingual urban primary care setting.

DESIGN

Patients 18 years and older within a New York City public hospital serving a large proportion of non-native-born Americans were surveyed regarding their cancer risk beliefs and patient activation in Haitian Creole, Spanish, or English based on language preference during a health care visit.

RESULTS

The sample (N = 460) included 150 Haitian Creole speakers, 159 Spanish speakers, and 151 English speakers and was primarily non-White (92%). Most participants (84%) had not been born in the United States. Cancer risk beliefs differed across language preference. Beliefs that cancer could be avoided by minimizing thoughts about cancer risk were significantly higher in Haitian Creole speakers than in others; reported negative emotion when thinking about cancer risk was higher in Spanish and English than in Haitian Creole speakers. These cancer risk beliefs were positively related to patient activation, even when controlling for language preference.

CONCLUSION

Cancer risk beliefs differ across language preference and are related to patient activation, making them potentially important in cancer control. Consideration of language represents important demographic stratification for understanding the frequency and relevance of different beliefs about cancer and patient activation.

The role of conviction in personal disease risk perceptions: What can we learn from research on attitude strength?

Perceived risk for disease is included as a predictor of intentions and behavior in many health behavior theories. However, perceived risk is not always a strong predictor of intentions and behaviors. One reason may be suboptimal conceptualization and measurement of risk perceptions; in particular, research may not capture the conviction and certainty with which a risk perception is held. The rich and independent literature on attitudes might be leveraged to explore whether conviction is an important moderator of the effects of risk perceptions on intentions and behavior. Attitudes are more predictive of intentions when they are high in multiple aspects of attitude strength, including attitude certainty and being more accessible and stable over time. Working from the assumption that risk perceptions have a similar structure and function to attitudes, we consider whether factors known to strengthen the attitude-behavior correspondence might also strengthen the risk perception-behavior correspondence. Although by strict definition risk perceptions are not evaluations (a critical component of attitudes), the predictive validity of risk perceptions may be increased by attention to one's "conviction" or certainty of perceived risk. We also review recent strategies designed to improve risk perception measurement, including affective and experiential assessments of perceived risk and the importance of allowing people to indicate that they "don't know" their disease risk. The aim of this paper is to connect two disparate literatures-attitudes and persuasion in social psychology with risk perceptions in health psychology and decision science-in an attempt to stimulate more work on characteristics and proper measurement of risk perceptions.

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.

Examining Intuitive Cancer Risk Perceptions in Haitian-Creole and Spanish-Speaking Populations

BACKGROUND

There is a developing emphasis on intuition and affect in the illness risk perception process, yet there have been no available strategies to measure these constructs in non-English speakers. This study examined the comprehensibility and acceptability of translations of cancer risk beliefs in Haitian-Creole and Spanish.

METHOD

An established, iterative, team-based translation process was employed. Cognitive interviews (n = 20 in Haitian-Creole speakers; n = 23 in Spanish speakers) were conducted in an inner-city primary care clinic by trained interviewers who were native speakers of each language. Use of an established coding scheme for problematic terms and ambiguous concepts resulted in rewording and dropping items.

RESULTS

Most items (90% in the Haitian-Creole version; 87% in the Spanish version) were highly comprehensible.

DISCUSSION

This work will allow for further research examining health outcomes associated with risk perceptions across diverse, non-English language subgroups, paving the way for targeted risk communication with these populations.

Perceived cancer risk and risk attributions among African-American residents of a low-income, predominantly African-American neighborhood

OBJECTIVE

In some national surveys, African-Americans have had lower scores on perceived cancer risk items than whites. Our goals were to confirm low perceptions of cancer risk in an African-American community sample and explore participants' attributions for their perceived cancer risk.

DESIGN

Data were from three cross-sectional surveys. We report levels of perceived absolute and comparative cancer risk in a community sample of African-Americans (N = 88), and African-Americans (Ns = 655, 428) and whites (Ns = 5262, 1679) from two nationally representative Health Information National Trends Surveys (HINTS). We analyzed the content of spontaneously-provided explanations for perceived risk from the community sample.

RESULTS

Perceived absolute and comparative cancer risk were lower in the community and national samples of African-Americans than in the national sample of whites. Participants' spontaneous attributions for low or lower than average risk included not having family history or behavioral risk factors, classes of attributions noted elsewhere in the literature. However, participants also explained that they wanted to avoid wishing cancer on themselves (positive affirmations) and hoped their risk was low (wishful thinking), responses rarely reported for majority-white samples.

CONCLUSIONS

Results provide further evidence that cancer risk perceptions are lower among African-Americans than whites. Some participant explanations for low perceived risk (wishful thinking, affirmations) are inconsistent with behavioral scientists' assumptions about perceived risk questions. Results reveal a need to expand cancer risk attribution typologies to increase applicability to diverse populations, and may indicate that perceived cancer risk questions have lower validity in African-American populations.
