Abstract
For many individuals harboring a variant of uncertain functional significance (VUS) in a homologous recombination (HR) gene, their risk of developing breast and ovarian cancer is unknown. Integral to the process of HR are BRCA1 and regulators of the central HR protein, RAD51, including BRCA2, PALB2, RAD51C and RAD51D. Due to advancements in sequencing technology and the continued expansion of cancer screening panels, the number of VUS identified in these genes has risen significantly. Standard practices for variant classification utilize different types of predictive, population, phenotypic, allelic and functional evidence. While variant analysis is improving, there remains a struggle to keep up with demand. Understanding the effects of an HR variant can aid in preventative care and is critical for developing an effective cancer treatment plan. In this review, we discuss current perspectives in the classification of variants in the breast and ovarian cancer genes BRCA1, BRCA2, PALB2, RAD51C and RAD51D.

Abstract
Breast cancer is still a lethal disease and the leading cause of death in women, undermining patients' survival and quality of life. Modern techniques of surgery and radiotherapy allow for the obtaining of good results in terms of survival, however they cause long-term side effects that persist over time, such as lymphedema and neuropathy. Similarly, the advent of new therapies such as endocrine therapy revolutionized breast cancer outcomes, but side effects are still present even in years of follow-up after cure. Besides the side effects of medical and surgical therapy, breast cancer is a real disruption in patients' lives considering quality of life-related aspects such as the distortion of body image, the psychological consequences of the diagnosis, and the impact on family dynamics. Therefore, the doctor-patient relationship is central to providing the best support both during treatment and afterwards. The aim of this review is to summarize the consequences of medical and surgical treatment on breast cancer patients and to emphasize the importance of early prevention of side effects to improve patients' quality of life.

Abstract
ABSTRACT The field of cancer genetic testing has made great advances in correctly identifying patients at risk for hereditary cancer syndromes. These tests, used during a genetic consultation, promote earlier detection of cancer and potentially increase survival. Despite these advancements, a large number of persons at risk for BRCA1/2 mutations remain untested due to a shortage of genetic counselors and lack of clinician knowledge on how to properly screen, identify, and refer patients to genetic counseling. We suggest team-based practices that physician associates/assistants (PAs) and NPs can use in collaboration with genetic counselors. We also explore how PAs and NPs can alleviate the burden on genetic counselors by taking a comprehensive family history, providing elements of counseling, and ordering appropriate genetic tests. This approach maximizes the amount of time the patient spends receiving actual genetic counseling. By creating this collaborative relationship, PAs and NPs can help increase the number of qualifying patients who receive genetic testing and counseling for hereditary breast and ovarian cancer syndromes.

Assessment of psychosocial difficulties by genetic clinicians and distress in women at high risk of breast cancer: a prospective study. Eur J Hum Genet 2022; 30:1067-1075. [PMID: 35399119 PMCID: PMC9437045 DOI: 10.1038/s41431-022-01096-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Revised: 03/03/2022] [Accepted: 03/22/2022] [Indexed: 12/12/2022] Open
Abstract
We examined how often genetic clinicians correctly identify psychosocial difficulties in women at high breast cancer risk and explored effects of this assessment and the genetic test result on counselees’ distress. A prospective observational study of counselee–clinician dyads was performed in three French, German and Spanish genetic clinics, involving 709 counselees (participation rate, 83.4%) and 31 clinicians (participation rate, 100%). Counselee–clinician agreement in perceived psychosocial difficulties was measured after the pre-test genetic consultation. Multivariate mixed linear models accounting for clinicians were tested. Predicted distress levels were assessed after the pre- (T1) and post-test result disclosure consultations (T2). Depending on the difficulty domain, clinicians adequately assessed the presence or absence of difficulties in 51% (“familial issues”) to 59% (“emotions”) of counselees. When counselees’ and clinicians’ perceptions disagreed, difficulties were generally underestimated by clinicians. Counselees’ distress levels remained stable from T1 to T2, irrespective of clinicians’ appraisal adequacy, and the genetic test result disclosure. Psychological referral need were found in 20–42% of counselees, more frequently observed for difficulties in the “emotions” domain. Our findings suggest that the genetic test result is a suboptimal indicator for psychological referral. Instead, clinicians should focus on emotions expressed by counselees to appraise their needs for psychological support.

Abstract
Purpose of Review Individuals carrying germline mutations in BRCA1/2 have unique psychosocial and educational needs that must be met to ensure informed clinical decision-making. In this review, we highlight the strategies used in clinical practice to support patients’ needs as well as currently available pre- and post-disclosure support interventions. Recent Findings Clinical risk communication is complicated by the uncertainty associated with gene penetrance, inconclusive results, variable effectiveness of surgical and screening interventions, and inadequate awareness of clinical genetics. Interventions to support patients’ psychosocial needs, and strategies for effective and scalable clinical risk communication are in routine use and largely effective at meeting patients’ needs. Research is underway to develop newer supportive resources; however, the inadequate representation of all mutation carriers persists. Summary Effective clinical risk communication strategies, decision support aids, written educational materials, and supportive psychosocial tools can together have a large impact on meeting BRCA carriers’ supportive needs.

Abstract
BACKGROUND Emotional distress associated with genetic testing for hereditary breast and ovarian cancer syndrome (HBOC) is reported to interfere with adherence to treatment and prophylactic measures and compromise quality of life. OBJECTIVES To determine levels of anxiety, depression, and quality of life in patients tested for pathogenic BRCA1/2 mutations and identify risk factors for the development of adverse psycho-emotional effects. METHODS Cross-sectional observational trial involving 178 breast or ovarian cancer patients from a referral cancer hospital in Northeastern Brazil. Information was collected with the Hospital Anxiety and Depression Scale (HADS) and the World Health Organization (WHO) Quality of Life (QoL) questionnaire (WHOQOL-BREF). RESULTS Patients suspected of HBOC had higher levels of anxiety than depression. The presence of (probably) pathogenic BRCA1/2 mutations did not affect levels of anxiety and depression. High schooling, history of psychiatric disease, and use of psychotropic drugs were directly associated with high anxiety. High schooling was too inversely associated with QoL as such a breast tumor. Anxiety and depression were directly correlated and both reduced significantly QoL. CONCLUSION Our results highlight the importance of psychological support and screening of risk factors for anxiety and depression and low QoL in HBOC patients at the time of testing.

Abstract
OBJECTIVE Cancer genetic counseling increasingly involves discussing uncertain test results, for example because multiple genes are sequenced simultaneously. This review was performed to provide insight into how counselors' communication of uncertain test results during genetic counseling for cancer affects counselors and counselees. METHODS A systematic mixed studies review was undertaken to review research on the effects of communicating uncertain test results. Four databases were searched using a PICO search strategy. Study findings of articles meeting the inclusion criteria were synthesized narratively. RESULTS Twenty-four articles were included. Uncertain test results encompassed either an inconclusive test result or a variant of unknown significance (VUS). Counselees involved almost exclusively women at risk of hereditary breast and/or ovarian cancer. None of the articles reported effects on counselor outcomes. Counselee outcomes were categorized as cognitive, affective or behavioral. Interpretation of a VUS was overall reported as difficult, and counselees' distress and worry were repeatedly found to decrease over time after the discussion of any uncertain test result. For most other outcomes, findings were sparse and/or inconsistent. CONCLUSION Evidence on effects on counselee outcomes is scant and inconsistent. Future studies are warranted to provide insight into how counselees and counselors are affected. PRACTICE IMPLICATIONS Clinical practice could benefit from guidelines on how to address uncertain test results during pre- and posttest genetic consultations.

Abstract
Screening programmes for BRCA1/2 Jewish Founder mutations (JFM) in the Jewish community have been advocated internationally. Implementation of these programmes could decrease morbidity and mortality of BRCA1/2 JFM carriers through the uptake of cancer screening strategies and risk-reducing surgery. An online programme offered to the Sydney Jewish community that delivers pre-test information and collects consent for BRCA1/2 JFM testing via a website is currently being evaluated (JeneScreen). Forty-three participants from JeneScreen were invited to participate in a sub-study, of semi-structured pre- and post-result telephone interviews. Eleven participants consented to the sub-study. The interviews explored their experiences regarding the online model of obtaining pre-test genetic information, giving consent and receiving results. Inductive thematic analysis was carried out on the interviews. Overarching themes identified include (1) embracing online testing, (2) the online pre-test experience, (3) the result notification experience, (4) concerns associated with online testing and (5) testing as a responsibility. Overall, participants were highly satisfied with online BRCA1/2 JFM testing, an indication that the a website for pre-test information provision is an acceptable alternative to in-person genetic counselling for BRCA1/2 JFM screening and represents a feasible model for future community screening efforts.

Abstract
Personalization of care through precision medicine and, more specifically, genetic testing is altering the treatment of breast cancer. Genetic testing is used in germline and tumor testing, with each providing distinct data to guide management. Germline testing supports more accurate risk evaluation to inform screening and risk-reducing medical and surgical strategies. Tumor testing can inform cancer recurrence risk assessment and cancer treatment options. This article reviews how genetic testing informs treatment and potential risks for a patient with breast cancer and her family. Hereditary cancer genetic testing of family members should include a discussion of potential results, adverse effects, clinical management options, and insurance coverage and address concerns about privacy or discrimination. Genetic professionals are available to assist with educating, testing, and treating patients with increased cancer risk.

Abstract
OBJECTIVES AND SETTING Advances in multigene panel testing for cancer susceptibility has increased the complexity of counselling, requiring particular attention to counselees' psychosocial needs. Changes in psychosocial problems before and after genetic testing were prospectively compared between genetic test results in women tested for breast or ovarian cancer genetic susceptibility in French, German and Spanish clinics. PARTICIPANTS AND MEASURES Among 752 counselees consecutively approached, 646 (86%) were assessed after the initial genetic consultation (T1), including 510 (68%) affected with breast cancer, of which 460 (61%) were assessed again after receiving the test result (T2), using questionnaires addressing genetic-specific psychosocial problems (Psychosocial Aspects of Hereditary Cancer (PAHC)-six scales). Sociodemographic and clinical data were also collected. RESULTS Seventy-nine (17.2%), 19 (4.1%), 259 (56.3%), 44 (9.6%) and 59 (12.8%) women received a BRCA1/2, another high/moderate-risk pathogenic variant (PV), negative uninformative, true negative (TN) or variant of uncertain significance result (VUS), respectively. On multiple regression analyses, compared with women receiving another result, those with a VUS decreased more in psychosocial problems related to hereditary predisposition (eg, coping with the test result) (ß=-0.11, p<0.05) and familial/social issues (eg, risk communication) (ß=-0.13, p<0.05), almost independently from their problems before testing. Women with a PV presented no change in hereditary predisposition problems and, so as women with a TN result, a non-significant increase in familial/social issues. Other PAHC scales (ie, emotions, familial cancer, personal cancer and children-related issues) were not affected by genetic testing. CONCLUSIONS In women tested for breast or ovarian cancer genetic risk in European genetics clinics, psychosocial problems were mostly unaffected by genetic testing. Apart from women receiving a VUS result, those with another test result presented unchanged needs in counselling in particular about hereditary predisposition and familial/social issues.

Experiences and interpretations of BRCA1/2 testing among women affected by breast or ovarian cancer who received a negative result. J Community Genet 2019; 10:501-514.

Abstract
The aim of this study was to retrospectively describe the genetic testing motives and experiences of women with a previous breast and/or ovarian cancer diagnosis, who received negative BRCA1/2 results including variants of unknown significance and no pathogenic variant detected. One hundred and thirteen women (mean age 56.17 years) were recruited from a familial cancer centre in metropolitan Australia, an average 3.4 years after undergoing testing. Participants completed a self-report questionnaire focusing on the retrospective experience of and motives for undergoing BRCA1/2 testing. The study found that the primary motives for undergoing BRCA1/2 testing were (a) to know more about whether their cancer was hereditary, and (b) to have more certainty about the risk of their children developing cancer. In terms of perceptions of personal risk, 35% of women perceived that their risk of breast cancer to be the same or lower than the general population and 80% believed the negative test result to mean that a risk-conferring gene had not been detected. Yet, the average estimate of the likelihood that their cancer was hereditary was 48 out of a possible 100. Psychologically, women did not interpret the negative BRCA1/2 result as a positive outcome. Half were not relieved by the result and were as or more worried than before. Psychological morbidity was high with 17%, 100%, and 36% experiencing clinically significant depression, anxiety, and cancer-specific distress, respectively. Self-ratings of the likelihood that their cancer was hereditary were more closely associated with their personal family cancer histories than with measures of psychological distress. These results have implications for adherence to risk-reducing behaviours and quality of life. Given that these women are not routinely followed up in clinical practice, these findings highlight the importance of post-test genetic counselling and longer-term follow-up for women with negative BRCA1/2 results. Additional time and emotional support from genetic counsellors may help this group of women make sense of the meaning of their test result and adjust psychologically, particularly to uncertainty around the cause of their family history.

Abstract
Background BRCA1 and BRCA2 mutations are associated with a higher risk of breast and ovarian tumors. This study evaluated the emotional states of women 1 month after having received the results of the genetic test and assessed eventual associations with the type of outcome, personal/familiar disease history and major socio-demographic variables. Methods The study, an observational retrospective one, involved 91 women, evaluated 1 month after receiving their results. Patients were administered the Hospital Anxiety and Depression Scale, the Profile of Mood States and emotional Thermometers. Results Anxiety was significantly higher than depression (p < 0.001), and 21.3% and 21.3% of the sample were, respectively, possible and probable cases for anxiety, whereas 13.5% and 10.1% were possible and probable cases for depression. Within the six mood states, Confusion-Bewilderment (M = 48.5) was the lowest, whereas Fatigue-Inertia (M = 52.3) was the highest. Differences were recorded within the ten assessed emotions too. Being a proband/nonproband and being or not a cancer patient were associated with many tested variables. Conclusion The psycho-emotional screening of women undertaking genetic counseling is relevant and should cover a large range of dimensions.

Abstract
Identifying germline BRCA pathogenic mutations in patients with ovarian or breast cancer is a crucial component in the medical management of affected patients. Furthermore, the relatives of affected patients can be offered genetic testing. Relatives who test positive for a germline BRCA pathogenic mutation can take appropriate action to prevent cancer or have cancer diagnosed as early as possible for better treatment options. The recent discovery that BRCA pathogenic mutation status can inform treatment decisions in patients with ovarian cancer has led to an increased demand for BRCA testing, with testing taking place earlier in the patient care pathway. New approaches to genetic counselling may be required to meet this greater demand for BRCA testing. This review discusses the need for best practices for genetic counselling and BRCA testing; it examines the challenges facing current practice and looks at adapted models of genetic counselling.

Effect on perceived control and psychological distress of genetic knowledge in women with breast cancer receiving a BRCA1/2 test result. Breast 2016; 31:121-127. [PMID: 27837705 DOI: 10.1016/j.breast.2016.10.024] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2016] [Revised: 10/27/2016] [Accepted: 10/28/2016] [Indexed: 01/28/2023] Open
Abstract
Information provision during BRCA1/2 genetic counseling is complex and expected to be increasingly so with gene panel testing. This prospective study evaluated whether genetic knowledge in counselees with breast cancer (BC) after a pre-test genetic counseling visit (T1) enhance their feeling of personal control while minimizing distress after the notification of BRCA1/2 result (T2). At T1, 243 (89% response rate) counselees completed questionnaires on genetic knowledge (BGKQ), perceived cancer genetic risk; of which, at T2, 180 (66%) completed the BGKQ again, scales of anxiety/depression, distress specific to genetic risk, and perceived control. Multilevel models were performed accounting for clinician, and testing an effect of knowledge on psychological outcomes according to the adequacy of counselees' perceived genetic predisposition to cancer. The mean knowledge score was moderate at T1, decreased while not significantly differing by BRCA1/2 test result at T2. Knowledge at T1 had no direct effect on psychological outcomes, but in counselees who over-estimated their cancer genetic risk, higher knowledge at T1 predicted higher specific distress at T2. In BC affected counselees who over-estimate their cancer genetic risk, higher BRCA1/2 pre-test genetic knowledge seem to lead to increased specific distress. Identifying these BC affected counselees who over-estimate their genetic cancer risk and helping them to interpret their genetic knowledge instead of providing them with exhaustive genetic information could minimize their distress after test result receipt.

PLoS One 2016; 11:e0158531. [PMID: 27428375 PMCID: PMC4948873 DOI: 10.1371/journal.pone.0158531] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2015] [Accepted: 06/17/2016] [Indexed: 11/19/2022] Open
Abstract
Background This study aims to understand the quality of life (QOL) and psychological state (PS) of Chinese breast cancer patients who received BRCA1/2 genetic testing; to examine the psychological changes between BRCA1/2 mutation carriers and non-carriers; and to further explore the psychological experience of BRCA1/2 mutation carriers. Methods This study was combined with quantitative and qualitative designs. First, we performed a quantitative investigation using FACT-B (Chinese version) and Irritability, Depression and Anxiety scale (IDA) to assess the QOL and PS in breast cancer patients who received BRCA1/2 genetic testing. Then semi-structured in-depth qualitative interviews among 13 mutation carriers were conducted in hospital. Results Results from the quantitative study showed QOL scores were relatively high and the IDA scores were relatively low among the patients, and there was no significant difference in the QOL or IDA scores between non-carriers and carriers. Based on the qualitative analysis, four main themes emerged: (1) Finding the reason for having breast cancer; (2) Negative emotions; (3) Behavioral changes; (4) Lack of information. Conclusions The present study showed that QOL and PS are good among the breast cancer patients who received genetic testing. Genetic testing itself does not cause long psychosocial effects. BRCA1/2 mutation carriers may have certain negative emotions at the first stage they knew the testing results and may initiate behavioral and lifestyle changes. The patients with a BRCA1/2 mutation desire knowledge with regard to genetic aspects in mainland China. Professional information and advice can be provided to relieve the patients’ negative emotions when they were informed of gene defect.

Abstract
BACKGROUND The emerging health care system increasingly values patient engagement and shared decision-making between patients and their providers. The practice of these values is gaining importance as the patient-centered medical home model and personalized medicine come into greater use. OPPORTUNITY FOR IMPROVEMENT Exploration of patient preferences about personal health data use for research and quality improvement is a fundamental element of the provider-patient relationship. Giving patients an explicit opportunity to discuss their options about use of their data and implementing a process that allows patients to receive desired communications about how their information is used can help build patient trust, a requirement for successful care partnerships. PRACTICE ADVANCEMENT Working to change organizational cultures that exclude patients from participation in important decisions related to personal health information use promotes a strong patient-provider relationship and, ultimately, lays the foundation for improved health care through expanded use of patient data.

Abstract
Breast cancer (BC) is the leading cancer among women worldwide and in 5-10 % of cases is of hereditary origin, mainly due to BRCA1/2 mutations. Therefore, the German Consortium for Familial Breast and Ovarian Cancer (HBOC) with its 15 specialized academic centers offers families at high risk for familial/hereditary cancer a multimodal breast cancer surveillance program (MBCS) with regular breast MRI, mammography, ultrasound, and palpation. So far, we know a lot about the psychological effects of genetic testing, but we know little about risk-correlated adherence to MBCS or prophylactic surgery over time. The aim of this study was to investigate counselees' adherence to recommendations for MBCS in order to adjust the care supply and define predictors for incompliance. All counselees, who attended HBOC consultation at the University Hospital Heidelberg between July 01, 2009 and July 01, 2011 were eligible to participate. A tripartite questionnaire containing sociodemographic information, psychological parameters, behavioral questions, and medical data collection from the German consortium were used. A high participation rate was achieved among the study population, with 72 % returning the questionnaire. This study showed a rate of 59 % of full-adherers to the MBCS. Significant predictors for partial or full adherence were having children (p = 0.0221), younger daughters (p = 0.01795), a higher awareness of the topic HBOC (p = 0.01795, p < 0.0001), a higher perceived breast cancer risk (p < 0.0001), and worries (p = 0.0008)/impairment (p = 0.0257) by it. Although the current data suggest a good adherence of MBCS, prospective studies are needed to understand counselees' needs to further improve surveillance programs and adherence to them. Adherence to the breast cancer surveillance program for women at risk for familial breast and ovarian cancer versus overscreening-a monocenter study in Germany.

Abstract
OBJECTIVES Identify and discuss the nursing implications of personalized and precision oncology care. DATA SOURCES PubMed, CINAHL. CONCLUSION The implications in personalized and precision cancer nursing care include interpretation and clinical use of novel and personalized information including genetic testing; patient advocacy and support throughout testing, anticipation of results and treatment; ongoing chronic monitoring; and support for patient decision-making. Attention must also be given to the family and ethical implications of a personalized approach to care. IMPLICATIONS FOR NURSING PRACTICE Nurses face increasing challenges and opportunities in communication, support, and advocacy for patients given the availability of advanced testing, care and treatment in personalized and precision medicine. Nursing education and continuing education, clinical decision support, and health systems changes will be necessary to provide personalized multidisciplinary care to patients, in which nurses play a key role.

Abstract
Background The current research into single nucleotide polymorphisms has extended the role of genetic testing to the identification of increased risk for common medical conditions. Advances in genetic research may soon necessitate preparation for the role of genetic testing in primary care medicine. This study attempts to determine what proportion of patients would be willing to undergo genetic testing for salt-sensitive hypertension in a primary care setting, and what factors are related to this willingness. Methods A cross-sectional study using a self-report questionnaire was conducted among outpatients in primary care clinics and hospitals in Japan. The main characteristics measured were education level, family medical history, personal medical history, concern about hypertension, salt preference, reducing salt intake, and willingness to undergo genetic testing for salt-sensitive hypertension. Results Of 1,932 potential participants, 1,457 (75%) responded to the survey. Of the respondents, 726 (50%) indicated a willingness to undergo genetic testing. Factors related to this willingness were being over 50 years old (adjusted odds ratio [ad-OR] = 1.42, 95% Confidence interval = 1.09 – 1.85), having a high level of education (ad-OR: 1.83, 1.38 – 2.42), having a family history of hypertension (ad-OR: 1.36, 1.09 – 1.71), and worrying about hypertension (ad-OR: 2.06, 1.59 – 2.68). Conclusions Half of the primary care outpatients surveyed in this study wanted to know their genetic risk for salt-sensitive hypertension. Those who were worried about hypertension or had a family history of hypertension were more likely to be interested in getting tested. These findings suggest that primary care physicians should provide patients with advice on genetic testing, as well as address their anxieties and concerns related to developing hypertension.

Abstract
BACKGROUND A few studies have explored the effects of disclosure of genetic testing results on chronic disease predisposition. However, these effects remain unclear in cases of hypertension. Reducing salt intake is an important nonpharmacological intervention for hypertension. We investigated the effects of genetic testing for salt sensitivity on salt restriction behavior using hypothetical genetic testing results. METHODS We conducted a cross-sectional study using a self-completed questionnaire. We enrolled consecutive outpatients who visited primary care clinics and small hospitals between September and December 2009 in Japan. We recorded the patients' baseline characteristics and data regarding their salt restriction behavior, defined as reducing salt intake before and after disclosure of hypothetical salt sensitivity genetic test results. Behavioral stage was assessed according to the five-stage transtheoretical model. After dividing subjects into salt restriction and no salt restriction groups, we compared their behavioral changes following positive and negative test results and analyzed the association between the respondents' characteristics and their behavioral changes. RESULTS We analyzed 1562 participants with a mean age of 58 years. In the no salt restriction group, which included patients at the precontemplation, contemplation, and preparation stages, 58.7% stated that their behavioral stage progressed after a positive test result, although 29.8% reported progression after a negative result (P < 0.001). Conversely, in the salt restriction group, which included patients at the active and maintenance stages, 9.2% stated that they would quit restricting salt intake following a negative test result, and 2.2% reported they would quit following a positive result (P < 0.001). Age < 65 years (adjusted odds ratio [OR] 1.74; 95% confidence interval [CI] 1.12-2.71), female gender (adjusted OR 1.84; CI 1.29-2.62), graduation from college or university (adjusted OR 1.66; CI 1.11-2.49), and desire for genetic testing (adjusted OR 4.53; CI 3.13-6.57) were associated with progression of behavioral stage in the no salt restriction group. Conversely, salt preference (adjusted OR 2.13; CI 1.31-3.49) was associated with quitting salt restriction in the salt restriction group. CONCLUSION Patients in the no salt restriction group show the possibility of progression from the behavioral stage to the action stage after testing positive for salt sensitivity. Conversely, patients in the salt restriction group, particularly those with a salt preference, would quit salt restriction after testing negative.

Abstract
Objetivo: Analizar la validez y la fiabilidad de la adaptación de la escala Perceived Personal Control (PPC) en el contexto español para pacientes portadoras de mutación en los genes BRCA1/2 responsables del cáncer de mama y ovario hereditario (CMOH). Método: Adaptación transcultural y validación de la escala Perceived Personal Control (PPC) desarrollada por Shiloh y colaboraradores mediante traducción, retrotraducción y validación a través de un análisis factorial exploratorio con rotación Oblimin en una muestra de 176 mujeres portadoras de genes BRCA 1/2 para CMOH. Resultados: La versión española de la PPC reduce a seis los nueve ítems de la escala original, dado que esta estructura es la que ofrece una solución factorial más satisfactoria. El análisis factorial mostró un solo factor que explica el 51,07% de la varianza, en el que todos los ítems tenían cargas factoriales por encima de 0,4. El coeficiente α de Cronbach fue de 0,84 para el conjunto de la escala, la cual permite obtener valores que oscilan entre 0 (bajo grado de percepción de control) y 2 (alto grado de percepción de control). Conclusiones: La adaptación española de la Escala de Percepción de Control (PPC6) posee propiedades psicométricas satisfactorias en la versión de 6 ítems con un solo factor, por lo que su utilización en contexto español Consejo Genético para cáncer hereditario parece adecuada.
