RESUMO

INTRODUCTION: Adherence to breast and colorectal cancer screenings reduce mortality from these cancers, yet screening rates remain suboptimal. This 2 × 2 RCT compared 3 theory-based interventions to usual care to simultaneously increase breast and colon cancer screening in women who were nonadherent to both screenings at study entry. DESIGN: RCT. SETTING/PARTICIPANTS: Women (n=692) who were nonadherent to both breast and colon cancer screenings and aged 51-75 years were recruited. Enrollment, intervention delivery, and data collection were completed between 2013 and 2017, and data analyzed in 2018. INTERVENTION: The randomized intervention included the following 4 groups: 3 intervention arms (personally tailored messages using a web-based intervention, phone delivery by a trained navigator, or both) compared with usual care. Women at an average risk for colon cancer were allowed to select either colonoscopy or stool test as their preferred colon cancer screening. Mammography was promoted for breast cancer screening. MAIN OUTCOME MEASURES: Outcome data at 6 months included self-report and medical records for screening activity. RESULTS: All intervention arms significantly increased receipt of either a mammogram or stool test compared with control (web: p<0.0249, phone: p<0.0001, web + phone: p<0.0001). When considering receipt of both mammogram and stool test, all intervention arms were significantly different from usual care (web: p<0.0249, phone: p<0.0003, web + phone: p<0.0001). In addition, women who were adherent to mammography had a 4.5 times greater odds of becoming adherent to colonoscopy. CONCLUSIONS: The tailored intervention simultaneously supporting both breast and colon cancer screenings significantly improved rates of obtaining one of the screenings and increased receipt of both tests. TRIAL REGISTRATION: This study is registered with the clinical trials identifier NCT03279198 at www.clinicaltrials.gov.

RESUMO

BACKGROUND: Colorectal cancer mortality could be decreased with risk-appropriate cancer screening. We examined the efficacy of three tailored interventions compared with usual care for increasing screening adherence. METHODS: Women (n = 1,196) ages 51 to 74, from primary care networks and nonadherent to colorectal cancer guidelines, were randomized to (1) usual care, (2) tailored Web intervention, (3) tailored phone intervention, or (4) tailored Web + phone intervention. Average-risk women could select either stool test or colonoscopy, whereas women considered at higher than average risk received an intervention that supported colonoscopy. Outcome data were collected at 6 months by self-report, followed by medical record confirmation (attrition of 23%). Stage of change for colorectal cancer screening (precontemplation or contemplation) was assessed at baseline and 6 months. RESULTS: The phone (41.7%, P < 0.0001) and combined Web + phone (35.8%, P < 0.001) interventions significantly increased colorectal cancer screening by stool test compared with usual care (11.1%), with ORs ranging from 5.4 to 6.8 in models adjusted for covariates. Colonoscopy completion did not differ between groups except that phone significantly increased colonoscopy completion compared with usual care for participants in the highest tertile of self-reported fear of cancer. CONCLUSIONS: A tailored phone with or without a Web component significantly increased colorectal cancer screening compared with usual care, primarily through stool testing, and phone significantly increased colonoscopy compared with usual care but only among those with the highest levels of baseline fear. IMPACT: This study supports tailored phone counseling with or without a Web program for increasing colorectal cancer screening in average-risk women.

RESUMO

PURPOSE: Identifying correlates of colorectal cancer screening (CRCS) is critical for cancer control and prevention. Classification tree analysis (CTA) is a potentially powerful analytic tool that can identify distinct population subgroups for which CRCS is influenced by any number of multivariable interactions. This study used CTA to identify correlates of CRCS for exclusive population subgroups. METHODS: Data were obtained from the 2007 Health Information National Trends Survey (HINTS) and analyzed in 2014. CTA was employed to determine the association between demographic (n = 11), psychosocial (n = 6), and numeracy (n = 3) variables and CRCS status of adults ≥50 years (n = 3,769). RESULTS: Overall CRCS rate was 66.9 %. Level of doctor avoidance (three categories) was the initial splitting variable, leading to a total of 21 terminal node subgroups of CRCS utilization: (1) avoid doctor, not for fear of illness/death [n = 625 (16.5 %), four subgroups]; (2) avoid doctor, fear illness/death [n = 366 (9.7 %), two subgroups]; (3) do not avoid doctor [n = 2,778 (73.7 %), 15 subgroups]. CONCLUSIONS: Doctor avoidance was an important behavioral influence on CRCS adherence. Use of CTA to identify unique characteristics within population subgroups has merit for tailoring future intervention strategies. Community-based approaches may be effective for reaching individuals who avoid routine doctor visits.

RESUMO

OBJECTIVES: To identify women with low mammography utilization. METHODS: We used Classification Tree Analysis among women aged 42-80 from the 2008 Behavioral Risk Factor Surveillance System (N = 169,427) to identify sub-groups along a continuum of screening. RESULTS: Women with neither a primary care provider nor health insurance had the lowest utilization (33.9%) and were 2.8% of the sample. Non-smoking women aged 55-80, with a primary care provider, health insurance, and income of $75,000 or more had the highest utilization (90.7%) and comprised 5% of the sample. CONCLUSION: As access to primary care providers and health insurance increases with the Affordable Care act, classification tree analyses may help to identify women of high priority for intervention.

RESUMO

BACKGROUND: The National Lung Screening Trial (NLST) research team reported reduced lung cancer mortality among current and former smokers with a minimum 30 pack-year history who were screened with spiral computed tomography scans compared with chest x-rays. The objectives of the current study were to examine, at 1-year follow-up: 1) risk perceptions of lung cancer and smoking-related diseases and behavior change determinants, 2) whether changes in risk perceptions differed by baseline screening result; and 3) whether changes in risk perceptions affected smoking behavior. METHODS: A 25-item risk perception questionnaire was administered to a subset of participants at 8 American College of Radiology Imaging Network/NLST sites before initial and 1-year follow-up screens. Items assessed risk perceptions of lung cancer and smoking-related diseases, cognitive and emotional determinants of behavior change, and knowledge of smoking risks. RESULTS: Among 430 NLST participants (mean age, 61.0 years; 55.6% men; 91.9% white), half were current smokers at baseline. Overall, risk perceptions and associated cognitive and emotional determinants of behavior change did not change significantly from prescreen trial enrollment to 1-year follow-up and did not differ significantly by screening test result. Changes in risk perceptions were not associated with changes in smoking status (9.7% of participants quit, and 6.6% relapsed) at 1-year follow-up. CONCLUSIONS: Lung screening did not change participants' risk perceptions of lung cancer or smoking-related disease. A negative screening test, which was the most common screening result, did not appear to decrease risk perceptions nor provide false reassurance to smokers.

RESUMO

Latina women are less likely to utilize cancer screening services than are non-Latina White women. The purpose of this study is to examine the relationship between preferred language (English vs. Spanish) and receipt of mammography and Pap-smear testing among US Latinas and non-Latinas. Cross-sectional analysis of the 2008 and 2010 Behavioral Risk Factor Surveillance System (BRFSS) surveys. While Latinas responding to the BRFSS in English or in Spanish had unadjusted lower odds of receiving mammography testing, in multivariable analysis Latinas responding-in-Spanish had 2.20 times the odds (OR = 2.20, 95 % CI, 1.90-2.55) of reporting mammography compared to non-Latinas. Similarly, Latinas responding-in- Spanish had lower unadjusted odds of receiving Pap-smear testing. However, Latinas responding-in-Spanish had 2.37 times the odds (OR = 2.37 CI, 2.04-2.75) of reporting having received Pap smear testing compared to non-Latinas in multivariate analysis. The results of this paper further confirm the "reversed associations" among Latinas and mammography and Pap smear testing described in previous studies and suggest that in addition to insurance status, preferred language may be a key variable contributing to the reversal phenomenon observed among Latinas.

RESUMO

BACKGROUND: We used a composite variable composed of insurance status, income, and race/ethnicity to investigate access-enhancing programs as a possible reason for "reversals of association" and large percent changes (LPC), between race/ethnicity and cancer screening, when comparing the unadjusted and adjusted ORs. METHODS: Data were from women aged 40-64 years, using the combined 2008 and 2010 Behavioral Risk Factor Surveillance System surveys. Recent mammography was within the past 2 years, and recent Pap testing was within the past 3 years. Initial analyses using all variables singly were followed by analyses that used the composite variable with the remaining covariates. RESULTS: Analyses with race/ethnicity singly indicated reversals of association for Hispanic women and higher estimated screening for black and Hispanic women than for white women. Analyses with the composite variable found no reversals of association, but there were several LPCs for Hispanic and black women, for lower income, and for uninsured women. White, uninsured, lower income women were among those with the lowest utilization. CONCLUSIONS: Results were consistent with the possibility that access-enhancing programs for lower income, uninsured and often non-white women can lead to overestimates of screening, reversals of association, and LPCs in multivariable analyses. Attention should be given to identifying LPCs to unadjusted ORs. Lower income, uninsured, white women are also a group at risk of extremely low mammography and Pap test utilization. IMPACT: Combining variables to create better-targeted population subgroups may help in the interpretation of analyses that produce reversals of association and LPCs for correlates of cancer screening utilization.

RESUMO

BACKGROUND: Response rates of national health surveys are decreasing, which potentially can bias obtained prevalence estimates. The purpose of this study is to evaluate the extent to which non-response impacts the representativeness of the 2000 Behavioral Risk Factor Surveillance System (BRFSS) sample compared to the 2000 Decennial Census. METHODS: The 2000 BRFSS had a median response rate of 48%, while the 2000 Decennial Census had a response rate of 67%. Representativeness of the BRFSS sample was evaluated on gender, race, ethnicity, age, household income and marital status. Prevalence of each factor in the BRFSS was compared to the prevalence found in the US Census on both the state and county levels. Prevalence differences between the BRFSS and Census were calculated and their association with response rates was evaluated using robust OLS regression and polytomous logistic regression. The relationship between prevalence differences and other survey design elements, such as data collection procedure and sampling fraction, was also explored. RESULTS: The BRFSS prevalence estimates diverged from the Census estimates on several sociodemographic factors even after adjustment for non-response/non-coverage. This was found on both the state and county levels; however, smaller absolute differences between the BRFSS and Census prevalence estimates were found for factors included in the non-response/non-coverage adjustment weight. Lower response rates (<40%) were associated with the under-representation of racial/ethnic minorities, women and younger individuals in the BRFSS survey. CONCLUSION: Future research should examine alternative approaches to increase response rate (eg, mixed mode) and to adjust for non-response (eg, multiple imputation).

RESUMO

OBJECTIVES: The objectives of the study were to investigate the attitudes and practices of pediatric emergency department (PED) physicians (MDs), MD extenders (MD's assistants [PAs], nurse practitioners [NPs]), and nurses (RNs) regarding their counseling of alcohol-using adolescent PED patients and to determine which, if any, PED clinician characteristics predict current counseling practice. METHODS: An Internet-based survey of PED clinicians (MDs, PAs, NPs, and RNs) from 11 academic US PEDs was conducted. Respondents were asked about their counseling training, current counseling practices, confidence in their counseling skills, importance of counseling, attitudes and beliefs about counseling, and demographic information. Univariate and multivariate analyses were performed to determine the relationship between clinician characteristics and counseling practice. RESULTS: Counseling practice was strongly associated with one's profession; PED MDs/PAs/NPs reported significantly higher rates of counseling alcohol-using adolescents than PED RNs. These 2 groups differed significantly in terms of counseling training and experience. Counseling training and experience remained significant predictors of counseling practice, even after controlling for profession and other covariates. Both groups had similar views on the importance of counseling, confidence in their ability to counsel, and counseling substance-using adolescent PED patients. CONCLUSIONS: Pediatric ED MDs/PAs/NPs differ significantly from PED RNs in their counseling training, experience, and practice. These findings have important implications for the training and support necessary to successfully implement PED counseling. Specifically, formal training in counseling during professional schooling and garnering counseling experience after completing training may be critical factors in promoting PED counseling.

RESUMO

BACKGROUND: Several studies have found that Hispanics and non-Hispanic blacks have statistically significantly higher adjusted OR for cancer screening tests compared to non-Hispanic whites, even though their crude percentages were lower than, or about equal to, those for the non-Hispanic whites. Most documentation is for mammography. This article investigates the prevalence of such unadjusted-to-adjusted "reversed associations" (RA) for Pap, colorectal, and prostate testing. We also investigate large percent changes (LPC) to the unadjusted ORs. METHODS: Data were from the 2004/2006/2008 Behavioral Risk Factor Surveillance System (BRFSS) and the 2000/2003/2005/2008 National Health Interview Survey (NHIS). Analyses used a consistent set of covariates. RESULTS: RAs were more common for non-Hispanic blacks than Hispanics, but Hispanics had a greater number of LPCs. RAs and LPCs occurred more often for Pap testing than colorectal and prostate testing. However, results from the BRFSS and NHIS were often not consistent. CONCLUSIONS: Attention should be given to the National Breast and Cervical Cancer Early Detection Program, as well as public programs addressing other cancers, as possible contributors to RAs and LPCs. Hispanics may show more RAs in analyses of future data. Discrepancies between the BRFSS and the NHIS also must be recognized and explained. IMPACT: This research highlights the need for vigilance regarding the results of analyses to identify race/ethnicity as a correlate of cancer screening. Results also direct attention to aspects of the results of multivariable analysis other than ORs and confidence intervals.

RESUMO

BACKGROUND: Process of change (POC) is a construct of the transtheoretical model that proposes to promote healthy behaviors. PURPOSE: African Americans participate in colorectal cancer (CRC) screening less often than whites, while disease onset is younger, and incidence and mortality from CRC are higher. METHODS: POC items for CRC screening were administered to 158 African Americans, the majority of whom were female (75.9%) and were not employed (85.4%). Confirmatory factor analysis was used to validate four factors reflecting the POC sub-domains. RESULTS: Support of the factor validity of the POC with internal consistency of standardized alpha for the four factors was found. A logistic regression showed predictive validity in predicting current screening stage for two of the four sub-domains. CONCLUSION: These data support the application of the POC to prediction of CRC screening intention among African Americans.

RESUMO

Women treated with chest radiation for a pediatric cancer have low mammography screening rates despite their high risk for breast cancer. This study characterized the relationship between perceptions of mammography and screening practices. A cross-sectional survey was administered to 523 women in North America who were treated with chest radiation before 21 years of age. Women with inconsistent mammography perceptions and practices were identified using the Pros and Cons of Mammography for perceptions and Transtheoretical Model stages of adoption for prior and intended screening practices. Classification and regression tree (CART) analysis was used to identify barriers to and facilitators of screening among women with positive and negative perceptions. Nearly one-third of the cohort had inconsistent perceptions and practices: 37.4% had positive perceptions and were not having mammograms; 27.6% had negative/neutral perceptions and were having mammograms. Regardless of perceptions, a recent physician's recommendation for mammography, age ≥ 40, and interest in routine health care were universally associated with mammography practices. For women with positive perceptions and a physician's recommendation, barriers to screening included high acceptance coping, low active-planning coping, and high internal health locus of control. For women with negative perceptions, acknowledging the importance of asymptomatic screening was associated with mammography.

RESUMO

OBJECTIVE: Data on repeat mammography rates are less available than for recent screening. Two large, population-based state surveys provide the opportunity to investigate repeat and recent mammography prevalence and correlates among California's diverse population. METHODS: Data were from women aged 55-79, using the 2001 and 2005 California Health Interview Surveys. The study assessed the prevalence and correlates of recent mammography (within the past two years) and repeat mammography (mammogram within the past two years and 3-11 mammograms within the past six years). RESULTS: Prevalence was 82.4% (recent) and 73.8% (repeat) in 2001, and 87.1% (recent) and 77.5% (repeat) in 2005. Correlates of lower rates were insurance status, no usual source of care, being a smoker, age 65-79, being Asian with no English proficiency, being never married, and lower absolute risk for breast cancer. Especially low ratios of repeat-to-recent mammography existed for the uninsured, and those using the emergency room or with no source of care. Unexpected findings in which unadjusted results were inconsistent with multivariable adjusted results occurred for Latinas with no English proficiency and women at 200-299% of poverty level. CONCLUSIONS: Several groups of women in California remain at-risk of lower mammography utilization. However, investigators should also be alert for instances where multivariable analyses seem particularly discrepant with crude rates.

RESUMO

The development and use of validated processes of change (POC) measures have received little attention in the literature despite their importance in the Transtheoretical Model. Using survey data (N = 2909), we examined the construct validity of a 22-item mammography POC scale by testing for factorial validity and factorial invariance across stage of change. We also used MANOVA with Tukey post-hoc tests to confirm stage differences in POC use (concurrent validity). Our results confirm the a priori correlated four-factor structure of this scale and provide some support for the measurement equivalence of this scale across stage, supporting comparisons of POC use across stage.

RESUMO

OBJECTIVE: To develop and evaluate the psychometric properties of a measure of motivation and life outlook (Getting-Out-of-Bed [GoB]). DESIGN: Secondary analysis of baseline and 6-month data from a longitudinal follow-up study of older breast cancer survivors. PARTICIPANTS: Women (N = 660) diagnosed with primary breast cancer stage I-IIIA disease, age >or=65 years, and permission to contact from an attending physician in four geographic regions in the United States (city-based Los Angeles, California; statewide in Minnesota, North Carolina, and Rhode Island). MEASUREMENT: Data were collected over 6-months of follow-up from consenting patients' medical records and telephone interviews with patients. Data collected included the 4-item GoB, health-related quality of life (HRQoL), breast cancer, sociodemographic, and health-related characteristics. RESULTS: Factor analysis produced, as hypothesized, one principal component with eigen values of 2.74(baseline) and 2.91(6-months) which explained 68.6%(baseline) and 72.7%(6-months) of total variance. In further psychometric analyses, GoB exhibited good construct validity (divergent: low nonstatistically significant correlations with unrelated constructs; convergent: moderate statistically significant correlations with related constructs; discriminant: distinguished high HRQoL groups with a high level of significance), excellent internal reliability (Cronbach's alpha 0.84(baseline), 0.87(6-months)), and produced stable measurements over 6-months. Women with GoB scores >or=50 at baseline were more likely at 6-months to have good HRQoL, good self-perceived health, and report regular exercise, indicating good predictive ability. CONCLUSION: GoB demonstrated overall good psychometric properties in this sample of older breast cancer survivors, suggestive of a promising tool for assessing motivation and life outlook in older adults. Nevertheless, because it was developed and initially evaluated in a select sample, using measures with similar but not exact content overlap further evaluation is needed before it can be recommended for widespread use.

RESUMO

The behavioral theory constructs most often used to study mammography utilization-perceived benefit, perceived susceptibility, self-efficacy, intention, and subjective norms-have neither been developed nor sufficiently tested among diverse racial/ethnic subgroups. The authors explored these constructs and their underlying assumptions relating to the social context of Filipina and Latina women. The mixed-methods study included testing construct measures in the multilingual surveys of a concurrent intervention study of 1,463 women from five ethnic groups. An intensive inductive investigation then targeted Latina and Filipina women to elucidate connections between social context and individual screening behavior. In-depth interviews were conducted with 11 key informant scholars, 13 community gatekeepers, and 29 lay women, and a supplemental study videotaped and interviewed 9 mother-daughter dyads. Three social context domains emerged: relational culture, social capital, and transculturation and transmigration. The meaning and appropriateness of the five behavioral constructs were analyzed in relation to these domains. In contradistinction to tenets of behavioral theory, the authors found that social context can influence behavior directly, circumventing or attenuating the influence of individual beliefs; contextual influences, synthesized from multiple perspectives, can operate at an unconscious level not accessible to the individual; and contextual influences are dynamic, contingent on distal and proximal forces coming together in a given moment and are thus not consistent with an exclusive focus at the individual level. This article describes the study methods, summarizes main findings, and preview the detailed results presented in the other articles in this issue.

RESUMO

Intention, self-efficacy, perceived susceptibility, perceived benefits, and subjective norms are key constructs of health behavior theories; their predictive validity for cancer screening has not been ascertained in multiethnic populations. Participants were 1,463 African American, Chinese, Filipina, Latina, and White women aged 40 to 74 interviewed by telephone in their preferred languages. The relationship between baseline constructs and mammography 2 years later was assessed using multivariable logistic regression. Intention predicted mammography overall and among Whites (odds ratio [OR] = 5.0, 95% confidence interval [CI] = 2.4, 10), with racial/ethnic differences in association (p = .020). Self-efficacy predicted mammography overall and among Whites (OR = 3.5, 95% CI = 1.1, 11), with no racial/ethnic interaction. Perceived benefits and subjective norms were associated with screening overall and in some racial/ethnic groups. These results generally support cross-cultural applicability of four of the five constructs to screening with mixed predictive value of measures across racial/ethnic groups. Additional in-depth inquiry is required to refine assessment of constructs.

RESUMO

This article describes the influences of social context on women's health behavior through illustration of the powerful influences of social capital (the benefits and challenges that accrue from participation in social networks and groups) on experiences and perceptions of self-efficacy. The authors conducted inductive interviews with Latino and Filipino academics and social service providers and with U.S.-born and immigrant Latinas and Filipinas to explore direct and indirect influences of social context on health behaviors such as mammography screening. Iterative thematic analysis identified themes (meanings of efficacy, spheres of efficacy, constraints on efficacy, sources of social capital, and differential access to and quality of social capital) that link the domain of social capital with the behavioral construct perceived self-efficacy. The authors conclude that social capital addresses aspects of social context absent in the current self-efficacy construct and that these aspects have important implications for scholars' and practitioners' understandings of health behavior and intervention development.

RESUMO

INTRODUCTION: Breast cancer control efforts could benefit from estimating mammography prevalence at the substate level because studies have primarily analyzed health survey data at the national and state levels. The purpose of this study was to evaluate the extent to which geographic disparities exist in mammography use across counties in the contiguous United States. METHODS: We estimated county-level prevalence of recent mammography (past 2 years) for women aged 40 to 79 years by using synthetic regression, a small-area estimation method. The 2000 Behavioral Risk Factor Surveillance System (BRFSS), 2000 Census, Area Resource File, and Food and Drug Administration mammography facility data were merged by BRFSS respondents' county of residence. We conducted separate analyses to produce county-level prevalence estimates for each race and age group. RESULTS: Mammography use varied geographically, and the magnitude of geographic disparities differed by race and age. Nonwhite women showed the lowest prevalence of mammography and widest range in county-level estimates. Women aged 40 to 49 had generally lower prevalence than other age groups, while women aged 65 to 79 showed the greatest variation in county-level mammography estimates. CONCLUSION: Small-area estimation using BRFSS data is advantageous for surveillance of mammography use at the county level. This method allows documentation of geographic disparities and improves our understanding of the spatial distribution of mammography prevalence. Future interventions should consider this county-level geographic variation, targeting women in the neediest counties.

RESUMO

OBJECTIVES: Unmarried women with disabilities may be a particularly vulnerable group for underutilization of repeat mammography screening. Our goal was to compare the breast cancer screening experiences of unmarried women with disabilities (WWD) versus women with no disabilities (WND), and determine whether these experiences are associated with adherence to repeat screening. METHODS: We conducted a matched cohort study of 93 WWD and 93 WND to compare mammography experiences by disability status, examine rates of repeat mammography by disability status, and identify factors that are associated with repeat mammography. RESULTS: WWD were less likely to be on-schedule than WND in univariable (54.8% vs. 71.0%; relative risk, 0.77; 95% confidence limits, 0.61, 0.97), but not multivariable, analyses. In multivariable analyses, there was a significant interaction between disability status and positive experiences as the reasons for returning to the same mammography facility. Among WND, repeat screening ranged from 59% to 86%, depending on the number of positive experiences endorsed (range, 1-5). In contrast, among WWD, screening rates were only 37% among those who did not report any positive experiences and increased to a maximum of 60% regardless of whether women endorsed one to four or all five positive experiences. Severity and type of disability were not associated with repeat screening. CONCLUSION: WWD may be less likely than WND to remain on-schedule for mammography. WWD who do not report any positive experiences as reasons for returning to a mammography facility may be at particularly high risk of underutilization of screening.
