Factors associated with repeat mammography screening.

BACKGROUND: Even organizations with differing mammography recommendations agree that regular repeat screening is required for mortality reduction. However, most studies have focused on one-time screening rather than repeat adherence. We compare trends in beliefs and health-related behaviors among women screened and adherent to the National Cancer Institute's screening mammography recommendations (on schedule), those screened at least once and nonadherent (off schedule), and those never screened. METHODS: Our data are from a baseline telephone interview conducted among 1,287 female members of Blue Cross Blue Shield of North Carolina who were aged either 40 to 44 years or 50 to 54 years. RESULTS: The 3 groups differed significantly on beliefs and health-related behaviors, with the off-schedule group almost consistently falling between the on-schedule and never screened groups. Off-schedule women were more likely than on-schedule women, but less likely than those never screened, to not have a clinical breast examination within 12 months, to be ambivalent about screening mammography, to be confused about screening guidelines, and to not be advised by a physician to get a mammogram in the past 2 years. Off-schedule women perceived their breast cancer risk as lower and were less likely to be up to date with other cancer screening tests. CONCLUSIONS: Our findings suggest that women who are off schedule are in need of mammography-promoting interventions, including recommendations from and discussion with their health care providers. Because they are more positive and knowledgeable about mammography than women who have never been screened, they may benefit from brief interventions from health care providers that highlight the importance of repeat screening.

How effective is tailored print communication?

This article reviews the "first generation" of tailored print communications studies in the published literature, describing the purpose, theoretical framework, sample, research design, message type and source, outcomes measured, and findings of each. Eight studies compared tailored versus similar nontailored print; one compared tailored print versus an alternate intervention, and three included tailored print as one of several intervention components. Although studies varied by behavioral topic, type of tailoring, and measurement of behavioral outcomes, several themes persist. Compared to their nontailored counterparts, tailored print communications have been consistently better remembered, read, and perceived as relevant and/or credible. There is also evidence that tailored print communications are more effective for influencing health behaviors. Six of the eight tailored/nontailored comparisons found more behavior change among tailored than nontailored recipients. Tailored print communications have also demonstrated effectiveness as an adjunct to other intervention components such as self-help smoking cessation manuals. However, studies comparing tailored print communications with tailoring via other media such as telephone counseling have shown mixed results. Additional research is needed to assess whether the behavioral topic itself may make a difference in whether tailoring is appropriate and effective.

Using the telephone to improve health behavior and health service delivery.

The technology for using the telephone to deliver interventions to improve health behavior and health care has expanded dramatically and exciting innovations continue to emerge. These developments enable the telephone to be used to deliver individualized services to a broad cross section of target groups, while minimizing logistic and system barriers, and cost. However, as telephone-delivered interventions have proliferated, a number of questions remain concerning the elements that are essential to their effectiveness. We provide a broad overview of telephone interventions, published in the past 10 years to identify gaps in knowledge about these services, and make recommendations for future program development and evaluation.

The impact of tailored interventions on a community health center population.

We conducted a 4-year randomized study in a community health center that serves primarily low income Blacks in Durham, North Carolina. Patients (1318 at baseline) were assigned randomly to one of three study groups: provider prompting intervention alone, provider prompting and tailored print materials or the previous group and tailored telephone counseling. The purpose of the study was to determine whether increasingly intensive, tailored print and telephone interventions also were increasingly effective in promoting adherence to mammograms, Pap tests and overall cancer screening compliance. Thus, the combination of tailored print interventions (print and telephone) should have been more effective than the provider prompting intervention alone, or the print intervention and prompting combination. This is one of the few studies to examine a measure of overall cancer screening compliance and to assess the benefit of combinations of tailored interventions in promoting adherence to cancer screening. Patients gave extremely high ratings to the interventions. At the bivariate level, we found a significant effect of the most intensive group (provider prompting intervention, tailored print communications and tailored telephone counseling) on Pap test compliance (P = 0.05) and borderline significance at the multivariate level (P = 0.06) as well on overall screening compliance (P = 0.06). There was not a significant effect on mammography, probably because a majority of the patients were receiving regular mammograms. We also found some important subgroup differences. For example, a larger proportion of women reported Pap tests in the tailored print and counseling group when they believed the materials were 'meant for me.' These results show that a combination of tailored interventions may have potential for reaching the women who have too often been labeled the 'hard to reach.'

Using tailored interventions to enhance smoking cessation among African-Americans at a community health center.

This prospective randomized study examined the impact of three tailored intervention approaches to increase quitting rates among African-American smokers who were clients of a community health center that serves primarily low-income and indigent persons. Smokers were randomized to one of three groups: (1) health care provider prompting intervention alone, (2) health care provider prompting intervention with tailored print communications, and (3) health care provider prompting intervention with tailored print communications and tailored telephone counseling. Among the 160 smokers who completed the study, 35 (21.8%) had quit smoking at follow-up. Smokers who received the provider prompting intervention with tailored print materials were more likely to report having quit than smokers who received the provider intervention alone (32.7% vs. 13.2%, p < 0.05). Smokers who received all three intervention components were not more likely to report having quit at follow-up than those who only received the provider intervention (19.2% vs. 13.2%). Smokers who at baseline were less educated, smoked less than half a pack of cigarettes per day, had a stronger desire to quit, felt more efficacious, and had thought about quitting were more likely to report having quit at follow-up. These results provide support for continued refinement of tailored communications to aid smoking cessation among African-American smokers.

Confusion about mammography: prevalence and consequences.

Over the last decade, there has been significant controversy about the schedule on which women, particularly women in their 40s, should have mammograms. The purpose of the analysis reported here was to assess whether women in their 40s and 50s were confused as a result of the controversy following the January 1997 National Institutes of Health Consensus Development Conference on Breast Cancer Screening For Women Ages 40-49. We also examined if confusion was related to being off schedule for mammography. The study sample included 1287 women recruited from a random sample of 2165 Blue Cross/Blue Shield of North Carolina members. The data described in this analysis were derived from a baseline telephone interview conducted as part of a larger intervention trial. Study measures included a variety of sociodemographic, medical, belief, and behavioral variables. Overall, 28% of women were confused, and 35% were off schedule. Although a higher proportion of women in their 40s than 50s were confused, more women in their 50s were off schedule. Confusion was a significant predictor for the outcome being off schedule. Predictors of confusion included several belief variables, risk perceptions, age (40s), whether the woman had a regular physician, and whether she had enough information about mammography. Healthcare providers should ask some simple questions to determine if women are confused and then seek to meet their information needs.

Is there a use for tailored print communications in cancer risk communication?

The manner of presentation of cancer risk information is critical to its understanding and acceptance by the individual recipient. Optimal communication of cancer risk information must effectively translate the technical meaning and subtleties of risk and its associated factors to a conceptual level understandable by the recipient. Tailored print communications (TPCs) may be an appropriate medium for cancer risk communication (CRC). TPCs are more refined than targeted communication materials. They are print materials created especially for an individual on the basis of knowledge about that person. The goal is to provide individually relevant and appropriate information. This review examines the nature of TPCs, assesses the use and potential of TPCs for the purpose of CRC, and highlights new directions in CRC. Articles dealing with TPCs were located by searching the MEDLINE(R) and PsychInfo(R) databases and seeking in-press articles. TPCs were identified for several areas of CRC, including dietary change, smoking cessation, mammography use, hormone replacement therapy, health risk appraisal, and genetic susceptibility to cancer. Although TPCs have been used in a number of different behavioral areas, they have not yet achieved their potential for CRC. The use of TPCs in the communication of cancer risk shows great promise, however, particularly as knowledge evolves regarding both the nature of risk and the most effective tailoring of health communication messages.

Attitudes, knowledge, and risk perceptions of women with breast and/or ovarian cancer considering testing for BRCA1 and BRCA2.

PURPOSE: This study examined baseline knowledge, beliefs, and risk perceptions among a group of 200 women with breast and/or ovarian cancer who participated in a trial designed to improve decision making about genetic testing for BRCA1 and BRCA2. PATIENTS AND METHODS: Women were identified by self-referral, physician referral, and tumor registry extraction and invited to participate in a randomized trial in which testing for BRCA1 and BRCA2 was offered free of charge. Subjects completed baseline questionnaires and interviews that assessed knowledge, attitudes, and perceptions of risk of having an alteration in BRCA1 or BRCA2. RESULTS: Sixty percent of women overestimated their chances of having a BRCA1 or BRCA2 mutation compared with estimates from a BRCA1/BRCA2 risk model. Women who have at least three relatives with breast or ovarian cancer were one third (95% confidence interval, 0.2 to 0.6) as likely to overestimate their risk of having a BRCA1 or BRCA2 mutation compared with women who have two or fewer affected relatives. Knowledge was limited about BRCA1 and BRCA2 mutations and cancer risk associated with gene mutations. Eighty-four percent of the women indicated a probable or definite interest in testing. CONCLUSION: A high proportion of the high-risk women in this study had knowledge deficits about BRCA1 and BRCA2 and overestimated their risk of having a mutation. Although some degree of caution should be used in generalizing the results of this study to practice settings, the data provide insight into the challenges clinicians will face in communicating with patients about cancer genetics.

A randomized trial of breast cancer risk counseling: the impact on self-reported mammography use.

OBJECTIVES: We evaluated the impact of individualized breast cancer risk counseling on mammography use among women at risk for breast cancer. METHODS: Participants (n = 508) were randomized to the breast cancer risk counseling intervention or a general health education control intervention, and 85% completed follow-up. RESULTS: In multivariate modeling, a significant group-by-education interaction demonstrated that among less-educated participants, breast cancer risk counseling led to reduced mammography use. There was no intervention effect among the more-educated participants. CONCLUSIONS: These results suggest that standard breast cancer risk counseling could have an adverse impact on the health behaviors of less-educated women.

Dissemination of an evidence-based intervention manual to improve managed care mammography rates.

After collaborating with the Centers for Disease Control and Prevention to develop an evidence-based mammography intervention manual, the dissemination of the manual in a managed care setting was assessed. Using qualitative methods (in-depth interviews), factors were examined that motivated use of the manual by the quality improvement units of eight Prudential HealthCare health plans. Seven of the plans implemented more intensive interventions after having received the manual than in the previous year. Factors that facilitated use of the manual and implementation of recommendations included: internal motivation, support of senior level management, adequate resources (time, personnel, and funds) to support interventions, and the organization and content of the manual itself.

Strategies to encourage mammography use among women in senior citizens' housing facilities.

BACKGROUND: This randomized trial evaluated the impact of mammography-enhancing interventions implemented in 40 senior citizens' housing facilities in Pennsylvania and North Carolina. METHODS: After stratification of the facilities according to the socioeconomic status and racial backgrounds of their residents, they were randomly assigned to one of four groups to receive the following: 1) standard care--a Medicare mammography benefit flier; 2) education--the flier and a community education program; 3) access--the flier, mammography appointments, and transportation; 4) combined--all interventions. Telephone surveys, conducted prior to any intervention, identified mammography-eligible women, who were re-surveyed six months later to ascertain mammography use. RESULTS: Logistic regression analyses identified mammography intention, age, and the interaction between ever having had mammography and being in the combined intervention group to be significant predictors of mammography use at six months. However, no significant main effect was found for any of the interventions. CONCLUSIONS: These results suggest that the combination of community-directed mammography education and access to mammography appointments encourages mammography use primarily by women who are already predisposed to having mammography. However, individually targeted and tailored interventions may be needed to encourage mammography use among women who have never had mammography and/or express no intention of having it done.

Predictors of mammography use among women veterans.

We examined mammography use patterns of women veterans and explored Veterans Administration (VA) health care use and military experience as predictors of mammography use by this population. We conducted a national telephone survey of women veterans. A sample of 397 women veterans was selected from all military discharges from 1971 through 1994. A 3 x 2 stratification scheme was used: three age groups (35-49, 50-64, > or = 65 years old) and two VA user groups indicating whether (VA user) or not (VA nonuser) they received any health care from a VA Medical Center in the last 5 years. The response rate was 75% (297 of 397). Analyses included bivariate techniques and weighted logistic regression. We found that women veterans told to have a mammogram by a health care professional were more than five times more likely to have ever had a mammogram (OR 5.41, CI 4.63-6.32) and nearly twice as likely to have had a mammogram within the past 2 years (OR 1.81, CI 1.57-2.09) as those who were not told to do so, controlling for age, race, VA user status, and length of military service. Regular VA users were more likely to have had a mammogram ever and within the past 2 years, controlling for other factors. Mammography use was not necessarily at a VA medical center. Interventions that promote better provider-patient communication and target older women veterans may have the most potential benefit. Whether VA health care is filling an important gap in access to mammography for older women veterans is an important policy question and warrants further research.

Overestimation of hereditary breast cancer risk.

OBJECTIVE: To find out how women with breast or ovarian cancer rate their chances of carrying hereditary factors for these cancers and to determine the extent to which they overestimate their risk. SUMMARY BACKGROUND DATA: BRCA1 and BRCA2 are genes that cause breast and ovarian cancer when they are inherited in families. Testing for disease-associated mutations in these genes is now available commercially. Previous studies have shown that women overestimate their chances of carrying mutations. However, women's perceptions of risk have not been compared to objective estimates or to actual BRCA1 and BRCA2 testing results. METHODS: This study examines estimates of carrying BRCA1 and BRCA2 mutations among women participating in a randomized trial comparing alternative precounseling educational materials. Estimates were provided by participants in a baseline mailed survey. Estimates given by participants were compared to those given by an expert panel and by a statistical model. Testing was offered free of charge and was done in an academic laboratory using standard techniques. Baseline estimates of participating women were compared to the estimates of the expert panel, to the carrier probability provided by the statistical model, and to actual testing results. RESULTS: Women who have a personal history of breast or ovarian cancer significantly overestimate their risk of carrying hereditary factors for breast and ovarian cancer. Self-estimates exceeded the estimates of experts and a statistical model. One hundred women completed testing, and 21 mutations in BRCA1 or BRCA2 were found. Many test-negative women also overestimated their hereditary risk. Some women with a high carrier probability were negative for BRCA1 and BRCA2 mutations. CONCLUSIONS: Overestimation of hereditary factors is common among affected women with a family history of cancer. Pretest education and counseling should reduce these high-risk perceptions. Better estimates of carrier probability will direct more intensive clinical services and research.

Informed consent for BRCA1 and BRCA2 testing.

While the cloning of BRCA1 and BRCA2 in 1994 and 1995 engendered great enthusiasm from cancer patients, their families and physicians, concerns about potential problems faced by those undergoing genetic testing were also evident. Although much can be learned from previous research on informed consent for testing and research for predictive genetic testing in diseases other than cancer, there are some specific issues related to cancer that make the questions more pressing, more difficult, and of larger social concern. Organizations such as the National Advisory Council for Human Genome Research, the American Society for Human Genetics, the American Society of Clinical Oncology and the Task Force for Genetic Testing have presented recommendations about informed consent for cancer susceptibility testing. However, many unanswered questions remain concerning the informed consent process. This review provides background on informed consent, summarizes studies that have been conducted in the area of genetic testing, with a focus on testing for BRCA1 and BRCA2, and details recommendations for achieving informed consent for genetic testing for cancer susceptibility and research on cancer genetics.

Awareness of cancer-related programs and services among rural African Americans.

African Americans are at increased risk for cancer and represent an important target population for programs such as Healthy People 2000, the Cancer Information Service (CIS), and the 5 a Day for Better Health Initiative. Yet, awareness of such programs among rural blacks is unknown. This study assessed awareness of these programs and determined related knowledge and beliefs among rural African Americans. It was undertaken as part of the baseline survey for the Black Churches United for Better Health project, a National Cancer Institute-funded initiative. A minority of respondents (n = 3737) demonstrated name recognition of Healthy People 2000 (23.4%), the CIS (42.4%), and the 5 a Day Program (40.7%). Far fewer (7.4%) were able to correctly identify the recommended daily number of servings of fruits and vegetables. Reported family history of cancer was associated with a greater tendency believe that eating more fruits and vegetables can prevent disease. These findings underscore the need for efforts to reach the rural black community with culturally sensitive and stage appropriate cancer prevention messages. Knowledge of family history of cancer may play an important role in targeting subgroups and delivering effective cancer prevention messages.
