Effectiveness of telephone counseling for mammography: results from five randomized trials.

BACKGROUND: Women over age 50 continue to be underscreened for breast cancer. The purpose of this report is to compare the effectiveness of a barrier-specific telephone counseling intervention across the five study sites of the Breast Cancer Screening Consortium (BCSC). METHODS: Each of the BCSC projects was a randomized study of the effectiveness of telephone counseling (TC) in comparison to a control condition. Eligible underusers were identified and surveyed by telephone before and after the implementation of the interventions. Data from a total of 3,461 underusers were analyzed. We tested whether significantly more women randomized to TC than to control were regular mammography users at the follow-up survey. Data were analyzed separately by site. RESULTS: Overall, TC was not significantly more effective than control in encouraging regular mammography. The pooled consortium-wide odds ratio was 1.08 (95% confidence interval: 0.91 to 1.27). CONCLUSIONS: TC has the potential to support maintenance of mammogram use. Modifications are needed to maximize this potential and additional methods should be used in conjunction with TC to reach women who are underusers of mammography.

Evaluating participants' use of a hormone replacement therapy decision-making intervention.

BACKGROUND: Associations between optimal use of a tailored decision-aid and levels of accuracy of perceived breast cancer risk, confidence in decision-making, and satisfaction with decisions about HRT were evaluated in a randomized intervention trial with a community sample of women aged 45-54. METHODS: Data are from 289 women randomized to receive a computer-tailored three-step decision-aid. RESULTS: Forty-seven percent of participants reported optimal use of the intervention materials. African American women and those with low confidence in decision-making were less likely to use the intervention optimally than white women and those with higher confidence (P<0.05). Optimal use of the decision-aid was associated with increased accuracy of perceived risk and confidence to make a decision. DISCUSSION: When used optimally, self-directed decision-aids can improve women's ability to make decisions about HRT. Additional refinement of these aids is needed. For some subgroups of women, adjuncts such as telephone counseling also might be considered.

The effect of a stage-matched and tailored intervention on repeat mammography(1).

BACKGROUND: Our objective was to determine whether a tailored, stage-matched educational intervention, guided by the transtheoretical model (TTM), would increase rates of repeat-screening mammography. DESIGN SETTING/PARTICIPANTS: A total of 1324 women (N=1026 after attrition) aged 50 to 74 years were recruited from a staff-model health maintenance organization. Some of the women were not due for mammograms at the time of recruitment. INTERVENTION: Women were randomly assigned to one of three intervention conditions: Group 1, no educational materials (usual care); Group 2, standard materials; and Group 3, stage-matched/tailored materials. Women in Groups 2 and 3 received a mailed education packet after both a baseline and a follow-up telephone interview. All women in Group 2 received the same materials regardless of differences in baseline mammography-related attitudes and behaviors. Each woman in Group 3 received materials based on her stage of adoption for mammography and TTM constructs. MAIN OUTCOME: Using clinical records, repeat screening was defined as receipt of a second mammogram within 14 months after obtaining an initial postbaseline mammogram. RESULTS: Women in Group 3 were more likely to obtain repeat-screening mammograms than women in Group 1 (44.2% vs 35.8%; adjusted rate ratio = 1.29, 95% confidence interval [CI]=1.11-1.46; adjusted rate difference = 0.06, 95% CI=-0.01-0.13). The screening percentage in Group 2 was intermediate (39.3%), and did not differ from either Group 3 or Group 1. CONCLUSIONS: The effect of the stage-matched/tailored intervention was sustained for repeat screening, although no educational materials were delivered to coincide with the timing for a second mammogram. However, the stage-matched/tailored intervention was not sufficient to have a substantial impact on screening beyond the effect of standard educational materials. Future interventions may need to administer "booster" sessions to increase repeat screenings.

Effects of a mammography decision-making intervention at 12 and 24 months.

BACKGROUND: Most women are not getting regular mammograms, and there is confusion about several mammography-related issues, including the age at which women should begin screening. Numerous groups have called for informed decision making about mammography, but few programs have resulted. Our research is intended to fill this gap. METHODS: We conducted a randomized controlled trial, which ran from 1997 to 2000. Women aged 40 to 44 and 50 to 54, who were enrolled in Blue Cross Blue Shield of North Carolina, were randomly assigned to one of three groups: usual care (UC), tailored print (TP) materials, or TP plus tailored telephone counseling (TP+TC). We assessed the impact of tailored interventions on knowledge about breast cancer and mammography, accuracy of breast cancer risk perceptions, and use of mammography at two time points after intervention-12 and 24 months. RESULTS: At 12 and 24 months, women who received TP+TC had significantly greater knowledge and more accurate breast cancer risk perceptions. Compared to UC, they were 40% more likely to have had mammograms (odds ratio=0.9-2.1). The effect was primarily for women in their 50s. TP had significant effects for knowledge and accuracy, but women who received TP were less likely to have had mammography. CONCLUSIONS: Decision-making interventions, comprised of two tailored print interventions (booklet and newsletter), delivered a year apart, with or without two tailored telephone calls, significantly increased knowledge and accuracy of perceived breast cancer risk at 12 and 24 months post-intervention. The effect on mammography use was significant in bivariate relationships but had a much more modest impact in multivariate analyses.

Pre-counseling education materials for BRCA testing: does tailoring make a difference?

Although tailored print materials (TPMs) have been assessed for a variety of behavioral targets, their effectiveness as decision aids for genetic testing had not been evaluated at the time this study began. We compared TPMs and non-tailored print material (NPMs) that included similar content about genetic testing for breast and ovarian cancer susceptibility. TPMs were prepared especially for an individual based on information from and about her. We mailed baseline surveys to 461 women referred by physicians or identified through a tumor registry. All had personal and family histories of breast and/or ovarian cancer and, on the basis of these histories, an estimated > or =10% probability of carrying a mutation in the breast/ovarian cancer genes BRCA1 or BRCA2. The 325 (70%) who responded were randomly assigned to receive TPM or NPM. Followup surveys, mailed 2 weeks following receipt of print materials, were returned by 262 women (81% of baseline responders). Participants were predominately white (94%) and well-educated (50% college graduates). The mean age was 49 years. At follow-up, TPM recipients exhibited significantly greater improvement in percent of correct responses for the 13-item true/false measure of knowledge (24% increase for TPM vs. 16% for NPM; p < 0.0001) and significantly less over-estimation of risk of being a mutation carrier (40% TPM group overestimated vs. 70% NPM; p < 0.0001). Anxiety did not differ significantly between groups. Reactions to materials differed on two items: "seemed to be prepared just for me" (76% TPM vs. 52% NPM; p < 0.001) and "told me what I wanted to know about BRCA1 and 2 testing" (98% TPM vs. 91% NPM; p < 0.05). TPMs showed an advantage in increasing knowledge and enhancing accuracy of perceived risk. Both are critical components of informed decision making.

The effectiveness of interventions to promote mammography among women with historically lower rates of screening.

This study examines mammography-enhancing intervention studies that focus on women in groups with historically lower rates of mammography use than the general population. These groups consist of women who are disproportionately older, poorer, of racial-ethnic minorities, have lower levels of formal education, and live in rural areas. We refer to them as diverse populations. The purpose of this report is to determine which types of mammography-enhancing interventions are most effective for these diverse populations. For this report, United States and international studies with concurrent controls that reported actual receipt of mammograms (usually based on self-report) as an outcome were eligible for inclusion. Intervention effects were measured by differences in intervention and control group screening rates postintervention and were weighted to reflect the certainty of each study's contribution. These effects differed significantly (Q = 218, 34 df), and the variation between studies was best explained by indicators of the use of access-enhancing approaches. Combined intervention effects were estimated for different categories of intervention types using random effects models for subgroups of studies. The strongest combination of approaches used access-enhancing and individual-directed strategies and resulted in an estimated 27% increase in mammography use (95% confidence interval, 9.9-43.9, nine studies). Additionally impressive was the access-enhancing and system-directed combination (20% increase and 95% confidence interval, 8.2-30.6, five studies). Access-enhancing strategies are an important complement to individual- and system-directed interventions for women with historically lower rates of screening.

Incorporating genetic susceptibility feedback into a smoking cessation program for African-American smokers with low income.

PURPOSE: Markers of genetic susceptibility to tobacco-related cancers could personalize harms of smoking and motivate cessation. Our objective was to assess whether a multicomponent intervention that included feedback about genetic susceptibility to lung cancer increased risk perceptions and rates of smoking cessation compared with a standard cessation intervention. EXPERIMENTAL DESIGN: Our design was a two-arm trial with eligible smokers randomized in a 1:2 ratio to Enhanced Usual Care or Biomarker Feedback (BF). Surveys were conducted at baseline, 6, and 12 months later. The setting was an inner city community health clinic. African-American patients who were current smokers (n = 557) were identified by chart abstraction and provider referral. All smokers received a self-help manual and, if appropriate, nicotine patches. Smokers in the BF arm also were offered a blood test for genotyping the GST(3) gene (GSTM1), sent a test result booklet, and called up to four times by a health educator. Prevalent abstinence was assessed by self-report of having smoked no cigarettes in the prior 7 days at the 6- and 12-month follow-ups and sustained abstinence, i.e., not smoking at either follow-up or in-between. RESULTS: Smoking cessation was greater for the BF arm than the Enhanced Usual Care arm (19% versus 10%, respectively; P < 0.006) at 6 months but not at 12 months. CONCLUSIONS: Smokers agreed to genetic feedback as part of a multicomponent cessation program. Although the program increased short-term cessation rates compared with standard intervention, genetic feedback of susceptibility may not benefit smokers with high baseline risk perceptions.

Factors associated with patient-recalled smoking cessation advice in a low-income clinic.

It is recommended that providers advise cessation to their patients who smoke. However, patients' reports of cessation advice indicate disparities based on patients' race, gender, age, and smoking level. Providers' reports do not corroborate these disparities. We investigated whether smokers who receive their care in a community health center recalled their providers advising them to quit smoking when their providers documented such advice. We examined 219 patient-provider dyads to assess factors associated with lack of agreement between providers' documentation and patient recall. Patients were asked to recall any provider advice to quit smoking in the post 2 years. After every visit, providers completed a form to record the content of the visit. Most of the patients were African American, married, and uninsured. Sixty-eight percent of the dyads agreed in their documentation/recall. Patient race was the only factor associated with lack of agreement; African-American patients were more likely than white patients to provide discrepant reports. Although this study can not disentangle the racial difference in patient-provider recall/documentation, results may indicate an important area in which health disparities exist. Future studies should address the dynamics of patient-provider communication about smoking cessation, especially in populations that include ethnically diverse patients.

Trust and sources of health information: the impact of the Internet and its implications for health care providers: findings from the first Health Information National Trends Survey.

BACKGROUND: The context in which patients consume health information has changed dramatically with diffusion of the Internet, advances in telemedicine, and changes in media health coverage. The objective of this study was to provide nationally representative estimates for health-related uses of the Internet, level of trust in health information sources, and preferences for cancer information sources. METHODS: Data from the Health Information National Trends Survey were used. A total of 6369 persons 18 years or older were studied. The main outcome measures were online health activities, levels of trust, and source preference. RESULTS: Analyses indicated that 63.0% (95% confidence interval [CI], 61.7%-64.3%) of the US adult population in 2003 reported ever going online, with 63.7% (95% CI, 61.7%-65.8%) of the online population having looked for health information for themselves or others at least once in the previous 12 months. Despite newly available communication channels, physicians remained the most highly trusted information source to patients, with 62.4% (95% CI, 60.8%-64.0%) of adults expressing a lot of trust in their physicians. When asked where they preferred going for specific health information, 49.5% (95% CI, 48.1%-50.8%) reported wanting to go to their physicians first. When asked where they actually went, 48.6% (95% CI, 46.1%-51.0%) reported going online first, with only 10.9% (95% CI, 9.5%-12.3%) going to their physicians first. CONCLUSION: The Health Information National Trends Survey data portray a tectonic shift in the ways in which patients consume health and medical information, with more patients looking for information online before talking with their physicians.

Attitudes, knowledge, risk perceptions and decision-making among women with breast and/or ovarian cancer considering testing for BRCA1 and BRCA2 and their spouses.

A limited number of studies have examined the involvement of spouses in the decision-making process for genetic testing as well as impact of the actual testing. This report presents data from 40 women with a personal history of breast and/or ovarian cancer who were considering genetic testing for BRCA1 and BRCA2 and their spouses. We examined knowledge and attitudes regarding genetic testing for breast cancer susceptibility, perceptions of the likelihood that their wives (the women) had a BRCA1 or BRCA2 mutation, pros and cons of genetic testing, spouses' satisfaction with their involvement in the decision-making process and additional resources they would find helpful. Knowledge about cancer genetics and genetic testing for BRCA1 and BCA2 was limited among both women and their spouses. Up to one-third of spouses indicated that they would like to avail themselves of additional sources of information about BRCA1 and BRCA2 testing. Most spouses indicated that they thought their wives had a mutation in BRCA1 or BRCA2 and that their wives' breast cancers would recur. Pros of genetic testing were emphasized more than cons among both parties. Overall, spouses were satisfied with their role in the decision-making process. Future interventions to improve the decision-making process regarding genetic testing for breast cancer susceptibility should be undertaken.

Coping styles and personality domains related to menopausal stress.

PURPOSE: Examine the role of coping styles and personality domains in relationship to stress associated with menopause. DATA/INFORMATION: Data are from 170 women ages 45 to 54 who completed a mailed questionnaire and a telephone interview that assessed women's stress associated with menopause, coping style, personality, menopausal symptoms, depressive symptoms, and use of hormone replacement therapy. RESULTS: Rating menopause as stressful was associated with higher levels of neuroticism, seeking social support, and avoidance, and lower levels of agreeableness in unadjusted analyses. In a multivariate model, menopausal symptoms, seeking social support, and neuroticism accounted for 21% of the variance in rating menopause as stressful. CONCLUSIONS: Health care providers treating women going through menopause should be aware that the stress response to the menopause transition is multifactorial and is associated with women's individual personalities and coping styles.

The Health Information National Trends Survey (HINTS): development, design, and dissemination.

Little is known about access, sources, and trust of cancer-related information, or factors that facilitate or hinder communication on a population-wide basis. Through a careful developmental process involving extensive input from many individuals and organizations, the National Cancer Institute (NCI) developed the Health Information National Trends Survey (HINTS) to help fill this gap. This nationally representative telephone survey of 6,369 persons aged > or = 18 years among the general population was first conducted in 2002-2003, and will be repeated biennially depending on availability of funding. The purpose of creating a population survey to be repeated on a cyclical basis is to track trends in the public's rapidly changing use of new communication technologies while charting progress in meeting health communication goals in terms of the public's knowledge, attitudes, and behaviors. The HINTS survey instrument was built upon extant models of health communication and behavior change, taking into account the rapidly changing communication environment. Questions in the survey were drawn from an overall theoretical framework that juxtaposed the"push" aspects of traditional broadcast media against the"pull" aspects of new media. HINTS data will be made widely available for researchers and practitioners; it will help further research in health communication and health promotion and provide useful information for programs, policies, and practices in a variety of settings.

Provider characteristics and mammography recommendation among women in their 40s and 50s.

OBJECTIVES: Healthcare provider recommendation for mammography is one of the strongest predictors of women's mammography use, but few studies have examined the association of provider characteristics with mammography recommendations. We examined the relationship of provider gender, age, medical specialty, and duration of relationship with the patient to report mammography recommendation. METHODS: Participants were women ages 40-45 and 50-55 who were part of a larger intervention study of decision making about mammography. We examined the relationship of provider characteristics to patient-reported mammography recommendations at baseline and at 24-month follow-up. RESULTS: At baseline, 74% of women in their 40s and 79% of women in their 50s reported provider mammography recommendations within the prior 2 years. Proportions were similar at the 24-month follow-up. In multivariate logistic regression models including both patient and provider characteristics, women in their 40s who had female providers were more likely to report mammography recommendations than those with male providers at baseline (OR=1.83, p=0.01) and follow-up (OR=1.74, p=0.03). Among women in their 50s, participants whose regular providers were primary care physicians were more likely to report recommendations at baseline than those whose regular providers were obstetrician/gynecologists (OR=1.68, p=0.03). CONCLUSIONS: About one fourth of women in this study reported not having been advised by a healthcare provider to have a mammogram. All women in the study had health insurance. Among women in their 40s, for whom mammography guidelines were controversial at the time of data collection, provider gender was an important predictor of patient-reported mammography recommendation.

Patterns of change in hostility from college to midlife in the UNC Alumni Heart Study predict high-risk status.

OBJECTIVE: To examine hostility measured in college and patterns of change in hostility from college to midlife as predictors of high health-related risk later in midlife. METHODS: Logistic regression models were used to test hostility/risk associations. RESULTS: College hostility predicted being a current smoker, consuming more than two drinks of alcohol, low social support, achieving less than expected in career and in relationships, risk for depression, and appraisal of life changing for the worse in terms of family events at midlife. Change in hostility did not predict smoking and drinking; however, it did significantly predict social isolation, lower income (only for women), obesity, avoidance of exercise, high-fat diet, and negative changes in economic life, work life, and physical health events-all risk indicators measured during the next decade. Appraisals of social support, lowered expectations, risk for depression, and reports of family life changing for the worse were predicted at both time periods. When change in hostility was modeled with college hostility, all risk indicators were significantly predicted by college hostility. CONCLUSIONS: High hostility in college and change in hostility from college to midlife predicts a full range of health risk indicators. When compared with the average population decline in hostility, gains in hostility at midlife are related to increased risk while declines in hostility are related to reduced risk. Higher midlife hostility is associated with increased odds of being in the higher risk group. Future research should focus on developing interventions to reduce hostility.
