Attitudes about genetic testing and genetic testing intentions in African American women at increased risk for hereditary breast cancer.

PURPOSE: To evaluate attitudes about the benefits, limitations, and risks of genetic testing for BRCA1 and BRCA2 (BRCA1/2) mutations and explore testing intentions in African American women at increased risk for hereditary breast cancer. METHODS: Attitudes and intentions were evaluated by telephone in African American women (n = 74) at moderate and high risk for having a BRCA1/2 mutation. RESULTS: Attitudes about the benefits of genetic testing were endorsed at a higher rate relative to limitations and risks; however, only 30% of respondents indicated that they would definitely have testing. In regression analysis, women most likely to be considering testing were those with fatalistic beliefs about cancer and those who believed they had a BRCA1/2 mutation. Women who had two or more affected relatives were also most likely to be considering testing. Women who had a personal history of cancer and those who believed they were at high risk for developing breast cancer were most likely to report greater limitations and risks. Pros scores were higher among women older than age 50 and those who were unemployed. CONCLUSION: Although African American women at moderate and high risk for BRCA1/2 mutations report favorable attitudes about genetic testing, interest in testing may be limited. Women affected with cancer and those who believe they are at a higher risk for developing breast cancer may be most concerned about the negative consequences of testing. Increased attention may need to be given to beliefs about genetic testing and testing motivations during genetic counseling with African American women.     

Interest in genetic testing among first-degree relatives of breast cancer patients

The recent cloning of a breast-ovarian cancer susceptibility gene (BRCA1), and determination of the locus of a related gene (BRCA2), offers potential for clinical genetic testing for breast cancer susceptibility. This study examined interest in and expectations about an impending genetic test among first-degree relatives (FDRs) of breast cancer patients. One hundred five females completed two structured telephone interviews to assess demographics, breast cancer risk factors, psychological factors, and attitudes about genetic testing for breast cancer susceptibility. Overall, 91% of FDRs said that they would want to be tested, 4% said they would not, and 5% were uncertain. The most commonly cited reasons for wanting genetic testing were to learn about one's children's risk, to increase use of cancer screening tests, and to take better care of oneself. Women with less formal education were motivated by childbearing decisions and future planning to a greater degree than were women with education beyond high school. Most women anticipated a negative psychological impact of positive test results, involving increased anxiety (83%), depression (80%), and impaired quality of life (46%). In addition, 72% of women indicated that they would still worry if they tested negative. In multivariate regression analysis, level of baseline depression was the strongest predictor of an anticipated negative impact of genetic testing (Beta =.15; P,.0001). These results suggest that the demand for genetic testing for breast cancer susceptibility may be great, even among women who are not likely to have predisposing mutations. Prior to widespread availability of such testing, it will be critical to develop informed consent protocols to educate individuals about the benefits and limitations of predictive testing for this multifactorial disease. © 1995 Wiley-Liss, Inc.     

Contribution of BRCA1 and BRCA2 germ-line mutations to the incidence of breast cancer in young women: results from a prospective population-based study in France

The prevalence of BRCA1/2 germ-line mutations was assessed in a prospective population-based series of early-onset breast cancer (BC) patients in France, and the usefulness of a clinical assessment of hereditary BC risk, based on multiple criteria including pedigree structure, was evaluated. Through the Rhone region BC registry, 232 women diagnosed with BC before 46 years of age were included. They were tested for BRCA1/2 mutations an average of 10 months after diagnosis. All the women were classified according to their family history of cancer: high risk of hereditary breast cancer (HBC), low risk of HBC, isolated BC, and unknown HBC risk. Deleterious mutations were observed in 21 women (9.1%): 15 (6.5%) BRCA1 and 6 (2.6%) BRCA2. Mutations were more prevalent in women who developed BC before age 41 than in women who developed BC between ages 41 and 45 (12.8% versus 5.2%, respectively, P = 0.04). A high prevalence of BRCA1/2 mutations was found among women in the high-risk category with particular family features (i.e., small family size, predominantly male pedigree, specific cancers; 23.5%) and among women with isolated BC before age 41 and with five or fewer close adult female relatives (16.6%). According to the 10% probability level recommended by the American Society of Clinical Oncology guidelines for genetic testing of cancer, BRCA1/2 mutation screening should be considered for all women diagnosed before age 41, except for those with isolated BC in a large pedigree including multiple unaffected female relatives. The clinical assessment of HBC risk that we have developed should help in the decision to perform genetic testing.     

Medical Mistrust Influences Black Women’s Level of Engagement in BRCA1/2 Genetic Counseling and Testing

Clinical evidence supports the value of BRCA1/2 genetic counseling and testing for managing hereditary breast and ovarian cancer risk; however, BRCA1/2 genetic counseling and testing are underutilized among black women, and reasons for low use remain elusive. We examined the potential influence of sociocultural factors (medical mistrust, concerns about genetic discrimination) on genetic counseling and testing engagement in a sample of 100 black women at increased risk for carrying a BRCA1/2 mutation. Eligible participants fell into 1 of 3 groups: (1) healthy women with at least 1 first-degree relative affected by breast and/or ovarian cancer, (2) women diagnosed with breast cancer at age less than or equal to 50 years, and (3) women diagnosed with breast and/or ovarian cancer at age greater than or equal to 50 years with either 1 first-degree relative or 2 second-degree relatives with breast and/or ovarian cancer. Participants were recruited from clinical and community settings and completed a semistructured interview. Study variable relationships were examined using bivariate tests and multivariate regression analysis. As expected, genetic counseling and testing engagement among this sample was low (28%). After accounting for sociodemographic factors and self-efficacy (β = 0.37, p < .001), women with higher medical mistrust had lower genetic counseling and testing engagement (β = -0.26, p < .01). Community-level and individual interventions are needed to improve utilization of genetic counseling and testing among underserved women. Along with trust building between patients and providers, strategies should enhance women’s personal confidence. The impact of medical mistrust on the realization of the benefits of personalized medicine in minority populations should be further examined in future studies.     

Association between temporal orientation and attitudes about BRCA1/2 testing among women of African descent with family histories of breast cancer

OBJECTIVE: Previous studies have identified specific attitudes (pros and cons) about BRCA testing held by women of African descent that are associated with decisions to participate in testing. These testing attitudes may be determined, in part, by temporal orientation, or how one perceives the significance of events and the consequences of their actions in terms of past, present, and future. The current study explored the relationship between temporal orientation and pros and cons of BRCA testing among 140 women of African descent with a family history suggestive of a genetic mutation predisposing to breast cancer. METHODS: Participants completed measures of temporal orientation and genetic testing attitudes. RESULTS: Multivariate analyses indicated that future orientation was positively associated with perceived pros of testing. Additional analyses revealed significant associations between temporal orientation and specific item subsets related to the negative and positive impact of testing on family and personal control over one's health. CONCLUSION: These results support an association between temporal orientation and attitudes about BRCA testing among women of African descent with family histories of breast cancer. PRACTICE IMPLICATIONS: Findings support exploration of temporal orientation in future research on BRCA testing decisions among women of African descent and this construct's importance in developing decision aids and tailoring genetic counseling.     

Genetic testing for breast cancer susceptibility: Awareness and interest among women in the general population

Previous research has suggested that demand for genetic testing for breast cancer susceptibility may be quite high, even among those at relatively low risk of carrying a mutation. This study examined the extent to which a group of female HMO enrollees were aware of the discovery of the BRCA1 gene and, without having received detailed information about the test, whether they would be interested in being tested to find out if they have the gene. Factors associated with awareness of and interest in testing were also examined. Four hundred seventy-three women age 50 and over, almost all of whom did not have an increased risk of breast cancer based on family history, were surveyed by telephone. Fifty-one percent of respondents had heard about the discovery of a breast cancer gene. In logistic regression analysis, women who described themselves as comfortable financially, had at least some college education, and were premenopausal were more likely to have heard of the gene discovery than women who were not comfortable financially, had no more than a high school education, and were postmenopausal. Sixty-nine percent of the respondents said that they would be interested in being tested to find out if they had a breast cancer gene. Women who were younger than 60, white, believed their family would benefit if they had a mammogram, and believed that regular mammograms give them a feeling of control over their health, were more likely to be interested in testing than those who were 60 or older, African-American or other, and did not believe that their family would benefit if they had a mammogram or that mammograms give them a feeling of control over their health. These findings have implications for education and counseling. Women who express an interest in being tested must be made fully aware of the limitations and possible consequences of testing. Special efforts may be needed to make information about testing available to women who have low levels of education. Am. J. Med. Genet. 68:43–49, 1997 © 1997 Wiley-Liss, Inc.     

Attitudes and distress levels in women at risk to carry a BRCA1/BRCA2 gene mutation who decline genetic testing

Genetic testing enables women at risk for hereditary breast and/or ovarian cancer to find out whether they have inherited the gene mutation, and if so, to opt for undergoing frequent surveillance and/or prophylactic surgery. However, the option to know about one's genetic status is not always seen as a benefit by women at risk. Motives for declining genetic testing were explored in 13 women at 25% or 50% risk to be a BRCA1/BRCA2 mutation carrier, who participated in a surveillance program for breast/ovarian cancer (the non-tested group). We hypothesized that high anxiety might be an important motive to decline testing. In addition, we investigated whether the non-tested group differed from a reference group of women who did undergo the test (tested group; n = 85) with regard to biographical factors, experience with cancer in relatives, and personality traits. Most non-tested women (10/13) were satisfied with participating in the surveillance program. Four reported to feel emotionally unprepared to cope with the consequences of testing. Compared with the tested group, the non-tested women had similar mean distress levels (which were not high), but a higher education level, they were more often childless, showed more reluctance towards prophylactic surgery, were younger when first confronted with a relative affected with breast/ovarian cancer, and were longer aware of the genetic nature of the disease. This study showed that women were more likely to have thoroughly reflected on their decision not to undergo genetic testing, than to deny the whole issue due to high anxiety. Being confronted at a relatively young age with breast/ovarian cancer in a relative, and being aware of the genetic risk for a many years, may have resulted in the risk for cancer becoming an integrated part of their lives. However, generalization of these results to women who neither underwent the test nor participated in a surveillance program should be considered with caution.     

BRCA1/2 testing in hereditary breast and ovarian cancer families II: impact on relationships

Members of hereditary breast and ovarian cancer (HBOC) families often express concern during genetic counseling about the impact of BRCA1/2 testing on close relatives. Yet whether there are likely to be adverse effects of either the decision to undergo genetic testing or the results of testing on family relationships is unknown. One purpose of this study was to assess the impact on close family relationships. Within a randomized trial of breast cancer genetic counseling methods, members of 13 HBOC families were offered BRCA1/2 testing for a known family mutation. The Family Relationship Index (FRI) of the Family Environment Scale (FES) was used to measure perceived family cohesion, conflict, and expressiveness at baseline and again 6-9 months following the receipt of test results, or at the equivalent time for those who declined testing. Participants (n = 212) completed baseline and follow-up questionnaires. Comparisons were made between testers and non-testers as well as between those who tested positive and negative for the family mutation. One hundred eighty-one participants elected to undergo genetic testing (85%) and 47 (26%) were identified to have a mutation. After adjusting for baseline family relationship scores, counseling intervention, gender and marital status, non-testers reported a greater increase in expressiveness (P = 0.006) and cohesion (P = 0.04) than testers. Individuals who tested positive reported a decrease in expressiveness (P = 0.07), although as a trend. Regardless of test decision or test result, those who were randomized to a client-centered counseling intervention reported a decrease in conflict (P = 0.006). Overall, study results suggest that undergoing genetic testing and learning ones BRCA1/2 status may affect family relationships. Those individuals who declined testing reported feeling closer to family members and more encouraged to express emotions to other family members demonstrating potential benefit from the offer of testing. Since those who tested positive reported feeling less encouraged to express their emotions within the family, we recommend helping clients to identify others with whom they feel comfortable sharing their thoughts and feelings about their positive gene status and increased cancer risk.     

Early use of clinical BRCA1/2 testing: associations with race and breast cancer risk

When BRCA1/2 testing became commercially available in 1996, many U.S. experts voiced concern about the potential for indiscriminate use of testing among low-risk women. Supporting this concern, several early surveys of interest in genetic testing suggested that genetic testing for cancer susceptibility might appeal most to individuals at low risk of carrying a mutation. To identify factors associated with early use of clinical BRCA1/2 testing, a case-control study was conducted at a large academic health system in the metropolitan Philadelphia region. A total of 167 women underwent genetic counseling for clinical BRCA1/2 testing between 1996 and 1997 (cases) compared with 138 women who were seen in faculty general internal medicine practices over the same period (controls). In this study we measured the risk factors for breast cancer, the risk factors for carrying a BRCA1/2 mutation, and sociodemographic characteristics. Use of BRCA1/2 counseling between 1996 and 1997 was positively associated with family but no personal history of breast cancer (odds ratio (OR), 22.4; 95% confidence interval (CI), 9.3-54.3); family and personal history of breast cancer (OR, 150.3; 95% CI, 24.1-939.6); being Caucasian and non-Jewish (OR, 4.1; 95% CI, 1.3-13.5); being Caucasian and Jewish (OR, 8.8; 95% CI, 2.2-35.5); and being married (OR, 3.2; 95% CI, 1.6-6.3). Use of BRCA1/2 counseling was inversely associated with increasing age (OR, 0.07; 95% CI, 0.02-0.28 for >60 compared to <50). As suggested by the association with family history, use of counseling was associated with having a higher predicted risk of breast cancer and a higher predicted risk of carrying a BRCA1 mutation (P < 0.0001). Women who sought clinical BRCA1/2 testing in the year after it became commercially available were not the "worried well," but women at significantly increased risk of carrying a mutation. However, even after adjusting for breast cancer risk, there was a substantial racial disparity in use of BRCA1/2 testing. These findings suggest that ensuring equal access to testing for high-risk individuals irrespective of race may be as important for the future of predictive genetic testing as restricting the use of testing among low-risk individuals.     

Results of a randomized study of telephone versus in-person breast cancer risk counseling

OBJECTIVE: Women of all risk levels have reported high interest in obtaining genetic testing for breast cancer risk. Breast cancer risk counseling may help women to learn about their risk and appropriate options of testing. This study measured the effects of an intervention in-person and by telephone, compared to a control group. METHODS: Participants were 340 women, recruited through a network of primary care physicians. They received a baseline questionnaire in the mail, were randomized to one of the three study arms, and completed a follow-up survey 3 months later. RESULTS: Both types of counseling were very well received. The counseling decreased women's cancer worry, risk perceptions, and intentions to pursue genetic testing. There were similar effects for both in-person and telephone counseling. CONCLUSION: Genetic counseling can be used to inform women at all risk levels about their breast cancer risk. PRACTICE IMPLICATIONS: Breast cancer risk counseling can be done in-person and by telephone--thereby reaching women in remote areas.     

Perceptions of Ashkenazi Jewish breast cancer patients on genetic testing for mutations in BRCA1 and BRCA2

The perceived benefits and risks of genetic testing may vary between groups of individuals with different cultural, demographic, and family history features. This multicentre study examined the factors that influenced the decision to undergo genetic testing for BRCA1 and BRCA2 in Canadian Jewish women with breast cancer. A self-administered questionnaire was developed and distributed to 134 individuals enrolled in a research-based testing program for Ashkenazi women. The questionnaire assessed demographic, social, and family history parameters, and the influence of medical, family, social, psychological, and cultural/religious factors on decision making about genetic testing. Seventy-six percent of women completed the questionnaire. Forty-one percent of study participants had no family history of breast or ovarian cancer. The most important factors influencing the decision to undergo testing were a desire to contribute to research, potential benefit to other family members, curiosity, and the potential for relief if not found to be a carrier (endorsed by 87, 78, 70, and 60% of participants, respectively). The main perceived risks of undergoing genetic testing related to insurance discrimination, confidentiality, accuracy and interpretability of results, potential impact on marriage prospects for family members, and focus on the Jewish community (endorsed by 28, 24, 30, 17, and 14% of participants, respectively). This study provides novel information on the motivating factors for BRCA1 and BRCA2 mutation testing in Canadian women of Ashkenazi Jewish descent. The focus on altruistic factors and those related to perceived psychological benefits of testing is notable.     

Life insurance and breast cancer risk assessment: adverse selection,genetic testing decisions,and discrimination

Life insurance industry access to genetic information is controversial. Consumer groups argue that access will increase discrimination in life insurance premiums and discourage individuals from undergoing genetic testing that may provide health benefits. Conversely, life insurers argue that without access to risk information available to individuals, they face substantial financial risk from adverse selection. Given this controversy, we conducted a retrospective cohort study to evaluate the impact of breast cancer risk information on life insurance purchasing, the impact of concerns about life insurance discrimination on use of BRCA1/2 testing, and the incidence of life insurance discrimination following participation in breast cancer risk assessment and BRCA1/2 testing. Study participants were 636 women who participated in genetic counseling and/or genetic testing at a University based clinic offering breast cancer risk assessment, genetic counseling, and BRCA1/2 testing between January 1995 and May 2000. Twenty-seven women (4%) had increased and six (1%) had decreased their life insurance since participation in breast cancer risk assessment. The decision to increase life insurance coverage was associated with predicted breast cancer risk (adjusted OR 1.03 for each 1% absolute increase in risk, 95% CI 1.01-1.10) and being found to carry a mutation in BRCA1/2 (OR 5.10, 95% CI 1.90-13.66). Concern about life insurance discrimination was inversely associated with the decision to undergo BRCA1/2 testing (RR 0.67, 95% CI 0.52-0.85). No respondent reported having life insurance denied or canceled. In this cohort of women, these results indicate that information about increased breast cancer risk is associated with increase in life insurance purchasing, raising the possibility of adverse selection. Although fear of insurance discrimination is associated with the decision not to undergo BRCA1/2 testing, there was no evidence of actual insurance discrimination from BRCA1/2 testing.     

Patient satisfaction and cancer‐related distress among unselected Jewish women undergoing genetic testing for BRCA1 and BRCA2

Metcalfe KA, Poll A, Llacuachaqui M, Nanda S, Tulman A, Mian N, Sun P, Narod SA. Patient satisfaction and cancer‐related distress among unselected Jewish women undergoing genetic testing for BRCA1 and BRCA2. It is not known to what extent participation in a genetic testing program for BRCA1 and BRCA2, which does not include an extensive pre‐test counselling session, influences cancer‐related distress, cancer risk perception and patient satisfaction. Unselected Jewish women in Ontario were offered genetic testing for three common Jewish BRCA mutations. Before testing and 1‐year post‐testing, the women completed questionnaires which assessed cancer‐related distress, cancer risk perception, and satisfaction. A total of 2080 women enrolled in the study; of these, 1516 (73%) completed a 1‐year follow‐up questionnaire. In women with a BRCA mutation, the mean breast cancer risk perception increased from 41.1% to 59.6% after receiving a positive genetic test result (p = 0.002). Among non‐carriers, breast cancer risk perception decreased slightly, from 35.8% to 33.5% (p = 0.08). The mean level of cancer‐related distress increased significantly for women with a BRCA mutation, but did not change in women without a mutation; 92.8% expressed satisfaction with the testing process. The results of this study suggest that the majority of Jewish women who took part in population genetic screening for BRCA1 and BRCA2 were satisfied with the delivery of genetic testing and would recommend testing to other Jewish women. However, women with a BRCA mutation experienced increased levels of cancer‐related distress.     

Knowledge About Genetic Risk for Breast Cancer and Perceptions of Genetic Testing in a Sociodemographically Diverse Sample

Informed consent for genetic testing for breast–ovarian cancer susceptibility requires that women understand basic concepts about the inheritance of cancer susceptibility and the benefits and risks associated with genetic testing. Women awaiting routine medical services (N = 220) were surveyed about their knowledge of breast cancer and cancer genetics and their perceptions of genetic testing and personal risk. There were no racial differences in median income or mean level of education. Compared to Caucasian women, African American women knew significantly less about breast cancer and about genetic risk for breast cancer. African American women had different psychological, social, and economic concerns as evidenced by how they weighted the benefits and risks of genetic testing. This study is the first to assess several dimensions of informed consent for genetic testing among a sociodemographically diverse group. The findings should enable health professionals to target the African American and lower-income populations with the appropriate education and counseling.     

Timing of BRCA1/BRCA2 genetic testing in women with ovarian cancer

PurposeTo determine when, in reference to the course of their treatment, women with ovarian cancer are seen for genetic counseling, as well as to determine what factors influence this timing.MethodsSingle institution retrospective chart review of patients with ovarian cancer who underwent BRCA1/BRCA2 genetic testing.ResultsThirty-three percent of our sample (n = 100) were seen for genetic counseling after ovarian cancer recurrence. In four cases, genetic test results were disclosed to next of kin. Thirty percent of women seen for genetic counseling after recurrence received their initial treatment elsewhere. Women with a history of breast cancer were significantly more likely to be seen for genetic counseling at an earlier phase of their treatment than women with no history of breast cancer.ConclusionWe found that one third of patients with ovarian cancer who underwent genetic testing were seen for initial genetic counseling after disease recurrence. In some cases, genetic counseling took place during the end of life care, with genetic test results disclosed to next of kin. Given the poor prognosis of women with recurrent ovarian cancer, we advocate providing genetic counseling at the time of initial ovarian cancer treatment both in comprehensive cancer centers and in community oncology settings.     

Psychosocial factors predicting BRCA1/BRCA2 testing decisions in members of hereditary breast and ovarian cancer families

Although BRCA1/2 testing has increasingly entered clinical practice, much is to be learned about the most effective ways to provide counseling to persons potentially interested in receiving test results. The purpose of this study was to identify factors affecting genetic testing decisions in a cohort of hereditary breast and ovarian cancer (HBOC) families presented with the choice to undergo testing. Relatives in these families are known to carry BRCA1 or BRCA2 mutations. Sociodemographics, personality traits, and family functioning were self-assessed using validated psychometric instruments at baseline. Among 172 individuals who participated in pretest education and counseling, 135 (78%) chose to undergo genetic testing and 37 (22%) chose not to be tested. Individuals who chose to undergo genetic testing were more likely to be older (> or =40 years), to have lower levels of optimism, and to report higher levels of cohesiveness in their families. A better understanding of factors that influence interest in predictive testing may help to inform the counseling that occurs prior to genetic testing.     

Low rates of acceptance of BRCA1 and BRCA2 test results among African American women at increased risk for hereditary breast-ovarian cancer.

PURPOSE: This study evaluated rates of BRCA1 and BRCA2 (BRCA1/2) test result acceptance among African American women and identified determinants of test result acceptance. METHODS: Acceptance of BRCA1/2 test results was evaluated among 157 African American women at high and moderate risk for having a BRCA1/2 mutation who were offered genetic testing as part of a clinical genetic counseling research program. RESULTS: Twenty-two percent of women received BRCA1/2 test results. Test result acceptance differed between women with > or =10% prior probability of having a BRCA1/2 mutation (34%) and those who had a 5% prior probability (8%). Among women with > or =10% prior probability, test result acceptors were most likely to be married (OR = 5.29, 95% CI = 1.82, 15.38, P = 0.002) and be less certain about their risk of developing cancer (OR = 3.18, 95% CI = 1.04, 9.80, P = 0.04). CONCLUSION: These results demonstrate that acceptance of BRCA1/2 test results may be limited among African American women. Being married and having less certainty about one's cancer risk may motivate acceptance of BRCA1/2 test results among African American women. It may be important to emphasize the possibility that BRCA1/2 test results may not clarify cancer risks during pre-test counseling with African American women to ensure informed decision-making about testing.

The impact of risk information exposure on women's beliefs about direct-to-consumer genetic testing for BRCA mutations

Despite an increase in direct-to-consumer (DTC) genetic testing, little is known about how variations in website content might alter consumer behavior. We evaluated the impact of risk information provision on women's attitudes about DTC BRCA testing. We conducted a randomized experiment; women viewed a 'mock' BRCA testing website without [control group (CG)] or with information on the potential risks of DTC testing [RG; framed two ways: unattributed risk (UR) information and risk information presented by experts (ER)]. Seven hundred and sixty-seven women participated; mean age was 37 years, mean education was 15 years, and 79% of subjects were white. Women in the RG had less positive beliefs about DTC testing (mean RG = 23.8, CG = 25.2; p = 0.001), lower intentions to get tested (RG = 2.8, CG = 3.1; p = 0.03), were more likely to prefer clinic-based testing (RG = 5.1, CG = 4.8; p = 0.03) and to report that they had seen enough risk information (RG = 5.3, CG = 4.7; p < 0.001). UR and ER exposure produced similar effects. Effects did not differ for women with or without a personal/family history of breast/ovarian cancer. Exposing women to the potential risks of DTC BRCA testing altered their beliefs, preferences, and intentions. Risk messages appear to be salient to women irrespective of their chance of having a BRCA mutation.     

Tolerance for uncertainty and perceived risk among women receiving uninformative BRCA1/2 test results

Women who receive uninformative BRCA1/2 genetic test results face ongoing uncertainty about their future cancer risks. This article prospectively examined the influence of intolerance for uncertainty and perceived breast cancer risk on psychological distress following the receipt of uninformative BRCA1/2 test results. Sixty-four women who received uninformative BRCA1/2 mutation test results completed measures of Intolerance for Uncertainty, perceived breast cancer risk, and measures of cancer-related, genetic testing, and general distress. Cancer-related (DeltaR(2) = 0.18, P < or = 0.001), general (DeltaR(2) = 0.04, P < or = 0.05), and genetic testing distress (DeltaR(2) = 0.12, P < or = 0.01) were associated with intolerance for uncertainty at 1 month post-disclosure. The interaction of intolerance for uncertainty and breast cancer perceived risk predicted cancer-related (DeltaR(2) = 0.10, P < or = 0.001) and genetic testing distress (DeltaR(2) = 0.09, P < or = 0.01) at 6 months post-disclosure. Distress was highest among patients with highest perceived risk and intolerance for uncertainty, suggesting that those who have difficulty coping with their ambiguous risk are at risk for long-term distress. The clinical and research implications of these results are discussed.
