Exploring genetic counseling communication patterns: the role of teaching and counseling approaches.

The educational and counseling models are often touted as the two primary professional approaches to genetic counseling practice. Yet, research has not been conducted to examine how these approaches are used in practice. In the present study, we conducted quantitative communication analyses of BRCA1 genetic counseling sessions. We measured communication variables that represent content (e.g., a biomedical focus) and process (e.g., passive listening) to explore whether genetic counselor approaches are consistent with prevailing professional models. The Roter Interaction Analysis System (RIAS) was used to code 167 pre-test genetic counseling sessions of members of a large kindred with an identified BRCA1 mutation. Three experienced genetic counselors conducted the sessions. Creating composite categories from the RIAS codes, we found the sessions to be largely educational in nature with the counselors and clients devoting the majority of their dialogue to providing biomedical information (62 and 40%, respectively). We used cluster analytic techniques, entering the composite communication variables and identified four patterns of session communication: Client-focused psychosocial, biomedical question and answer, counselor-driven psychosocial, and client-focused biomedical. Moreover, we found that the counselors had unique styles in which they combined the use of education and counseling approaches. We discuss the importance of understanding the variation in counselor communication to advance the field and expand prevailing assumptions.

How well do people recall risk factor test results? Accuracy and bias among cholesterol screening participants.

The authors conducted a community-based cholesterol screening study to examine accuracy of recall for self-relevant health information in long-term autobiographical memory. Adult community residents (N = 496) were recruited to participate in a laboratory-based cholesterol screening and were also provided cholesterol counseling in accordance with national guidelines. Participants were subsequently interviewed 1, 3, or 6 months later to assess their memory for their test results. Participants recalled their exact cholesterol levels inaccurately (38.0% correct) but their cardiovascular risk category comparatively well (88.7% correct). Recall errors showed a systematic bias: Individuals who received the most undesirable test results were most likely to remember their cholesterol scores and cardiovascular risk categories as lower (i.e., healthier) than those actually received. Recall bias was unrelated to age, education, knowledge, self-rated health status, and self-reported efforts to reduce cholesterol. The findings provide evidence that recall of self-relevant health information is susceptible to self-enhancement bias.

Preventing 3 million premature deaths and helping 5 million smokers quit: a national action plan for tobacco cessation.

In August 2002, the Subcommittee on Cessation of the Interagency Committee on Smoking and Health (ICSH) was charged with developing recommendations to substantially increase rates of tobacco cessation in the United States. The subcommittee's report, A National Action Plan for Tobacco Cessation, outlines 10 recommendations for reducing premature morbidity and mortality by helping millions of Americans stop using tobacco. The plan includes both evidence-based, population-wide strategies designed to promote cessation (e.g., a national quitline network) and a Smokers' Health Fund to finance the programs (through a 2 US dollar per pack excise tax increase). The subcommittee report was presented to the ICSH (February 11, 2003), which unanimously endorsed sending it to Secretary Thompson for his consideration. In this article, we summarize the national action plan.

Fertility intentions following testing for a BRCA1 gene mutation.

OBJECTIVE: To test whether fertility intentions differed among persons who tested positive, tested negative, or did not know their genetic status for a mutation of the BRCA1 gene. METHOD: Participants were members of a large Utah-based kindred with an identified mutation at the BRCA1 locus. Participants received genetic counseling prior to testing and were interviewed at baseline before testing and at three points after receiving test results from a genetic counselor. The sample included men and women who completed all interviews, were between ages 18 and 45, and were fertile, resulting in a sample of 101 respondents. The primary dependent variable measured whether a subject indicated that they were moderately or very sure at all three post-testing interviews that they intended to have additional children. Effects of BRCA1 mutation status on fertility intentions were estimated using multivariate logistic regressions where we controlled for gender, age, marital status, and baseline fertility intentions. RESULTS: Female carriers were less likely to want additional children in relation to female noncarriers (odds ratio 0.12, 95% confidence interval 0.01-1.23; P = 0.074). No differences were found among men. There was a significant difference in the effect of mutation status on fertility intentions between males and females (Gender x Carrier status interaction; P = 0.009). Persons who did not know their mutation status were less likely to want more children than noncarriers (odds ratio 0.09, 95% confidence interval 0.01-0.75; P = 0.027). CONCLUSION: Predictive genetic testing for late-onset cancer susceptibility affects family planning decision-making. Persons contemplating predictive testing should be informed about possible effects such testing may have on their plans for future fertility.

Genetic testing for a BRCA1 mutation: prophylactic surgery and screening behavior in women 2 years post testing.

Mutations in the BRCA1 gene are associated with an increased risk of breast and ovarian cancer in carrier women. An understanding of behavioral responses to BRCA1 mutation testing by mutation carriers and non-carriers is important to guide the clinical application of this new technology. This study examined the utilization of genetic testing for a BRCA1 mutation in high-risk individuals and the response of tested women with respect to interventions for early cancer detection and prevention. This study assessed the utilization of genetic testing for both men and women in a large kindred and the behavioral responses by women with respect to use of health care interventions during the 2 years following testing. Participants were offered BRCA1 mutation testing. Surveillance behaviors related to breast and ovarian cancer were assessed by computer-assisted telephone interviews at baseline (prior to genetic counseling and testing), 1-2 weeks, 4-6 months, 1 and 2 years after the provision of test results. Mutation carriers, non-carriers, and individuals of unknown mutation status were compared to determine the impact of test results. Utilization of genetic testing for both men and women are reported and, for women, mammography, breast self-exam, clinical breast exam, mastectomy, oophorectomy, transvaginal ultrasound, and CA125 screening were assessed. Of those fully informed of the opportunity for testing, 55% of the women and 52% of the men pursued genetic testing. With respect to mammography for women 40 years and older, 82% of mutation carriers obtained a mammogram in each year following testing compared to 72% of non-carrier women the first year and 67% the second year. This mammography utilization represents a significant increase over baseline for both mutation carriers and non-carriers. Younger carrier women also significantly increased their mammography utilization from baseline. Overall, 29% of the carrier women did not obtain a single mammogram by 2 years post-testing. At 2 years, 83% of the carrier women and 74% of the non-carriers reported adherence to recommendations for breast self-exam and over 80% of carrier women had obtained a clinical breast examination each year following testing. None of the carrier women had obtained a prophylactic mastectomy by 2 years after testing, although 11% were considering this procedure. Of carrier women 25 years of age and older who had at least one intact ovary at the time of testing, 46% of carriers had obtained an oophorectomy 2 years after testing, including 78% of women 40 years of age and older. The majority of carrier women (73%) had discussed their genetic test results with a medical doctor or health care provider. Our results indicate utilization of genetic testing by a majority of high-risk individuals who received information about testing. Both carriers and non-carriers increased their utilization of mammography and breast self-exam following testing. Oophorectomy was obtained by a large proportion of carrier women in contrast to mastectomy which was not utilized within the first 2 years following testing.

Awareness of genetic testing for increased cancer risk in the year 2000 National Health Interview Survey.

OBJECTIVES: This study explores factors associated with differential awareness of genetic tests for increased cancer risk in the US. METHODS: 27,405 respondents from the 2000 National Health Interview Survey, ages 25+, were asked if they had heard of these tests. RESULTS: 44.4% said 'yes', including 49.9% of whites, 32.9% of African-Americans, 32.3% of American Indians/Alaskan Natives, 28.0% of Asian/Pacific Islanders, and 20.6% of Hispanics. In multivariate analysis, test awareness was significantly associated with higher education, white race, age <60 years, female gender, private health insurance, personal or parent's history of certain cancers, physical activity, and vitamin/supplement use, among other factors. CONCLUSIONS: The survey showed which population subgroups may lack access to cancer genetics information and may therefore benefit from targeted strategies to ensure risk-appropriate utilization of genetic counseling and testing.

Cancer-related health disparities in women.

OBJECTIVES: This article synthesizes information about cancer in 9 populations of minority women: Mexican American, Puerto Rican, Cuban American, African American, Asian American, Native Hawaiian, American Samoan, American Indian, and Alaska Native. METHODS: Cancer registry data, social indicators, government sources, and published articles were searched for information on the background and cancer experience of these 9 racial/ethnic groups. RESULTS: Approximately 35 million women in these racial/ethnic groups live in the United States, and their numbers are increasing rapidly. Since 1992, incidence rates for major cancer sites have slowed or decreased among these groups, but declines in mortality have not occurred or have been smaller than for Whites. Gaps in early detection have narrowed, but minority women still lag behind Whites. Smoking and obesity remain common in these populations. CONCLUSIONS: More culturally appropriate interventions and research are needed, and these efforts must involve the community and raise the quality of health services.

Physician use of genetic testing for cancer susceptibility: results of a national survey.

Genetic testing for inherited germ-line mutations associated with cancer susceptibility is an emerging technology in medical practice. Limited information is currently available about physician use of cancer susceptibility tests (CSTs). In 1999-2000, a nationally representative survey was conducted to estimate prevalence of CST use by United States physicians and assess demographic, training, practice setting, and practice patterns associated with use. A stratified random sample of clinicians in eight specialties was selected from a file of all licensed physicians. In total, 1251 physicians, including 820 in primary care and 431 in tertiary care, responded to a 15-min questionnaire by mail, telephone, fax, or Internet (response rate = 71.0%). In the previous 12 months, 31.2% [95% confidence interval (CI), 28.5-33.9] overall, including 30.6% (95% CI, 27.5-33.7) in primary care and 33.4% (95% CI, 27.9-38.9) in tertiary care, had ordered CSTs or referred patients elsewhere for risk assessment or testing. More physicians referred patients elsewhere [26.7% (95% CI, 24.2-29.2)] than directly ordered tests [7.9% (95% CI, 6.3-9.5)]. Factors associated with ordering or referring included practice location in the Northeast [odds ratio (OR), 2.30; 95% CI, 1.46-3.63%], feeling qualified to recommend CSTs (OR, 1.96; 95% CI = 1.41-2.72), receiving CST advertising materials (OR, 1.97; 95% CI, 1.40-2.78%), and most notably, having patients who asked whether they can or should get tested (OR, 5.52; 95% CI, 3.97-7.67%). Lower CST use was associated with not knowing if there were local testing and counseling facilities (OR, 0.39; 95% CI, 0.23-0.66%). These findings underscore the importance of establishing effective clinical approaches to test use and promoting physician education to facilitate communication with patients about cancer genetics.

Genetic testing: psychological aspects and implications.

As the number of genes associated with inherited disease continues to grow, researchers and practitioners in behavioral medicine will encounter complex psychological issues faced by individuals at risk for these diseases. A review of the literature concerning prenatal, carrier, and predictive genetic testing suggests that the severity of psychological risks posed by research-based genetic testing is not great. However, subgroups of individuals with particular psychological traits may be more vulnerable to adverse effects. Available data do not provide evidence that genetic testing promotes changes in health-related behaviors. Thus, although there may be less of a role for mental health professionals in the psychological counseling of genetic testing participants, there is a need for research and practice to facilitate health protective behaviors in response to genetic risk information.

Screening behaviors among African American women at high risk for breast cancer: do beliefs about god matter?

PURPOSE/OBJECTIVES: To examine the relationship between beliefs about God as a controlling force in health and adherence to breast cancer screening among high-risk African American women. DESIGN: Cross-sectional cohort. SETTING: In-person interviews in rural, southeastern Louisiana and telephone interviews conducted at the University of Utah. SAMPLE: 52 females who were members of a large kindred with a BRCA1 mutation; no subjects had breast cancer. METHODS: Survey through in-person or telephone interviews. MAIN RESEARCH VARIABLES: Belief in God as a controlling agent over health measured by the God Locus of Health Control (GLHC) scale; screening behaviors measured by self-report. Adherence was based on consensus-approved recommendations for BRCA1 carriers or women at risk of being carriers. FINDINGS: Bivariate analysis indicated that presence of a primary care provider and low GLHC scores were associated with seeking clinical breast examination (CBE) and mammography. With the variable "presence of a primary care provider" excluded, GLHC scores were inversely associated with seeking CBE and mammography. CONCLUSIONS: African American women at increased risk for breast cancer and with high GLHC scores may have a decreased inclination to adhere to CBE and mammography recommendations. IMPLICATIONS FOR NURSING: Assessing religious and spiritual beliefs and incorporating belief systems into education and counseling sessions may improve understanding and acceptance of presented material.

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.

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.
