Abstract
INTRODUCTION Established personal and familial risk factors contribute collectively to a woman's risk of breast or ovarian cancer. Existing clinical services offer genetic testing for pathogenic variants in high-risk genes to investigate these risks but recent information on the role of common genomic variants, in the form of a Polygenic Risk Score (PRS), has provided the potential to further personalise breast and ovarian cancer risk assessment. Data from cohort studies support the potential of an integrated risk assessment to improve targeted risk management but experience of this approach in clinical practice is limited. METHODS AND ANALYSIS The polygenic risk modification trial is an Australian multicentre prospective randomised controlled trial of integrated risk assessment including personal and family risk factors with inclusion of breast and ovarian PRS vs standard care. The study will enrol women, unaffected by cancer, undergoing predictive testing at a familial cancer clinic for a pathogenic variant in a known breast cancer (BC) or ovarian cancer (OC) predisposition gene (BRCA1, BRCA2, PALB2, CHEK2, ATM, RAD51C, RAD51D). Array-based genotyping will be used to generate breast cancer (313 SNP) and ovarian cancer (36 SNP) PRS. A suite of materials has been developed for the trial including an online portal for patient consent and questionnaires, and a clinician education programme to train healthcare providers in the use of integrated risk assessment. Long-term follow-up will evaluate differences in the assessed risk and management advice, patient risk management intentions and adherence, patient-reported experience and outcomes, and the health service implications of personalised risk assessment. ETHICS AND DISSEMINATION This study has been approved by the Human Research Ethics Committee of Peter MacCallum Cancer Centre and at all participating centres. Study findings will be disseminated via peer-reviewed publications and conference presentations, and directly to participants. TRIAL REGISTRATION NUMBER ACTRN12621000009819.

[PMID: 38316954 PMCID: PMC11220043 DOI: 10.1038/s41431-024-01547-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 11/12/2023] [Accepted: 01/18/2024] [Indexed: 02/07/2024] Open
Abstract
The use of genomic data in research and genomic information in clinical care is increasing as technologies advance and sequencing costs decrease. Using Rogers' Diffusion of Innovation (DOI) theory as a framework we reviewed recent literature examining publics' current knowledge of, attitude to, and motivation towards health-related genomics in clinical and research settings. The population of interest was described as 'publics' to denote the heterogeneity of 'the public'. Eligible studies were published in English between 2016-2022. We retrieved 1657 records, with 278 full-text reviewed against the eligibility criteria and concept definitions. In total, 99 articles were included in the review and descriptive numerical summaries were collated. Knowledge literature was categorized using deductive thematic analysis. For attitude and motivation, literature was coded using an analytic framework developed by the authors. There was wide variability in concept definition and measurement across studies. Overall, there was general positivity about genomics, with high awareness but little familiarity or factual knowledge. Publics had high expectations of genomics and perceived that it could provide them with information for their future. Only a few key attitudes were found to be important as motivators or barriers for participation in genomics; these were related to personal and clinical utility of the information. Context was often missing from studies, decreasing the utility of findings for implementation or public engagement. Future research would benefit by using theory-driven approaches to assess relevant publics' knowledge and attitudes of specific contexts or applications to support genomic implementation and informed decision-making.

Abstract
Genetic counseling facilitates psychological and social adaptation in clients and families. Two psychotherapeutic approaches, narrative and family therapy foster client adaptation to adverse situations and may enhance the genetic counseling process. This scoping review aimed to describe the applications of narrative therapy and family therapy in genetic counseling, and to document the actual and perceived value of these approaches in a genetic counseling setting. Nine original research articles and six commentary articles met the study inclusion criteria. Original articles reported on positive client attitudes when these approaches were applied to hereditary cancer and Huntington disease settings. Five studies applied either approach in group sessions, where safety was key to positive outcomes, including sharing lived experiences and coping strategies. Balanced utilization of structured and open elements in group sessions maximized a sense of control, while also allowing for opportunity to self-disclose. Narrative therapy interventions were time efficient and were reported to foster connection with others and shape a new adaptive narrative centered around strengths. Family therapy approaches, based on experiential family therapy, the intersystem model, object relations family therapy, and the social ecology model, required a greater time commitment, but promoted disclosure of complex feelings and diffused tension. Family therapy genogram tools were feasible in practice, easy to implement, and effective at identifying communication barriers. Commentary articles highlighted the alignment of both approaches with genetic counseling goals and their potential value in practice. Utilization of psychotherapeutic approaches can improve counselors' ability to shape sessions, enhance insight and optimize efficacy, and flexibility in moving between models can maximize impact. This review highlights the paucity of studies investigating the efficacy of these psychotherapeutic approaches in the genetic counseling context and the need for more outcomes-based research on the utilization of narrative or family therapy in genetic counseling practice.

The value of pre-symptomatic genetic risk assessment for age-related macular degeneration: the Moran AMD Genetic Testing Assessment (MAGENTA) study-a study protocol for a randomized controlled trial. Trials 2023; 24:414. [PMID: 37337222 PMCID: PMC10278319 DOI: 10.1186/s13063-023-07436-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Accepted: 06/06/2023] [Indexed: 06/21/2023] Open
Abstract
BACKGROUND Age-related macular degeneration (AMD) is an irreversible blinding eye condition with complex genetic and environmental etiologies. Genetic testing for AMD for previously identified multiple-risk single nucleotide polymorphisms can help determine an individual's future susceptibility. However, such testing has been discouraged until evidence shows that providing such information to symptomatic or pre-symptomatic individuals will alter their disease course. Therefore, we designed this study to investigate whether knowledge of AMD risk could stimulate the adoption of a healthier lifestyle that could lower the incidence of AMD later in life. We hypothesize that pre-symptomatic individuals informed of a high genetic risk of AMD are more likely to make quantifiable, positive lifestyle changes relative to participants informed of lower genetic risk or randomized to deferred disclosure of genetic testing results. METHODS The Moran AMD Genetic Testing Assessment (MAGENTA) study is a phase 2, single-center, prospective, double-masked, randomized controlled trial conducted at the John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. Participants are randomized by a 3:1 allocation ratio to immediate and deferred disclosure groups and followed for 12 months. Skin, ocular, and serum carotenoid status, as well as nutritional and social surveys, are assessed at study visits. Skin carotenoid assessment is by resonance Raman spectroscopy and reflectance spectroscopy, ocular carotenoids are measured with Heidelberg Spectralis autofluorescence imaging and fluorescence lifetime imaging ophthalmoscopy (FLIO), and serum carotenoids are quantified using high-performance liquid chromatography. The primary outcome evaluates changes in skin carotenoid status in response to genetic risk disclosure. The secondary outcomes examine changes in ocular and serum carotenoid status in response to genetic risk disclosure. Also, we will correlate AMD genetic risk with baseline ocular and systemic carotenoid status and FLIO. DISCUSSION MAGENTA will provide much-needed evidence on whether pre-symptomatic testing for AMD risk can lead to quantifiable long-term changes in behavior and lifestyle associated with a lower incidence of AMD later in life. Findings from the MAGENTA trial will facilitate the design of a future larger, longer-term, multicenter phase 3 trial that could feature subgroup analysis, expanded measures of lifestyle modification, and potential active nutritional interventions.

Abstract
OBJECTIVE This study aimed to assess the use of a standardized prenatal genetic testing educational video and its effects on patient uptake of prenatal testing, patient knowledge, decisional conflict, and decisional regret. STUDY DESIGN This was an Institutional Review Board-approved randomized controlled trial. Patients were randomized to intervention (standardized video education) or control (no video education). The video education group viewed a 5-minute educational video on genetic testing options, and the control group did not review the video. Both groups answered validated questionnaires to assess maternal knowledge (Maternal Serum Screening Knowledge Questionnaire [MSSK]), conflict (Decisional Conflict Scale [DCS]), and regret (Decisional Regret Scale [DRS]). The primary outcome was genetic testing uptake; secondary outcomes were knowledge-based test score, and level of decisional conflict and regret. RESULTS We enrolled 210 patients between 2016 and 2020, with 208 patients randomized, 103 patients in the video education group and 105 patients in the control group. Four patients were excluded from the video education group for missing data. Video education was associated with a 39% lower chance of prenatal testing compared with patients who did not receive video education, (odds ratio 0.39, 95% confidence interval 0.16-0.92). Patients in the video education group had higher mean MSSKQ scores by 2.9 points (8.5 vs. 5.7, p < 0.001), lower Decisional Conflict Scores by 7.3 points (31.5 vs. 38.8, p < 0.001), lower Decisional Regret Scores by 5.4 points (23.8 vs. 29.2, p < 0.001). CONCLUSION We found that video education on prenatal genetic testing improved patients' knowledge, decreased testing and decisional conflict and regret regarding testing. This may indicate improved understanding of testing options and more informed decisions that align with their personal values and beliefs. This standardized video can be easily implemented in clinical practice to increase patient understanding and support decisions that align with patient's values. KEY POINTS · A standardized educational video improves patient knowledge about prenatal testing options in pregnancy.. · Video education decreases testing and decisional conflict and decisional regret in pregnancy.. · A standardized educational video may be used in the clinical setting to educate patients on testing options and help them make informed decisions about testing..

Abstract
PURPOSE Current practice recommendations support the widespread implementation of reproductive genetic carrier screening (RGCS). These consensus-based recommendations highlight a research gap, with findings from current studies being insufficient to meet the standard required for more rigorous evidence-based recommendations. This systematic review assessed methodological aspects of studies on RGCS to inform the need for a core outcome set. METHODS We conducted a systematic search to identify peer-reviewed published studies offering population-based RGCS. Study designs, outcomes, and measurement methods were extracted. A narrative synthesis was conducting using an existing outcome taxonomy and criteria used in the evaluation of genetic screening programs as frameworks. RESULTS Sixty-five publications were included. We extracted 120 outcomes representing 24 outcome domains. Heterogeneity in outcome selection, measurement methods and time points of assessment was extensive. Quality appraisal raised concerns for bias. We found that reported outcomes had limited applicability to criteria used to evaluate genetic screening programs. CONCLUSION Despite a large body of literature, diverse approaches to research have limited the conclusions that can be cumulatively drawn from this body of evidence. Consensus regarding meaningful outcomes for evaluation of RGCS would be a valuable first step in working towards evidence-based practice recommendations, supporting the development of a core outcome set.

Abstract
OBJECTIVE To investigate the effect of a genetic report format using risk communication "best-practices" on risk perceptions, in part to reduce risk overestimates. METHODS Adults (N = 470) from the Coriell Personalized Medicine Collaborative (CPMC) were randomized to a 2 × 2 experimental design to receive a hypothetical "personalized" genetic risk result for leukemia (relative risk = 1.5 or 2.5) through either the standard CPMC report (N = 232) or an enriched report informed by best practices (N = 238). A one-time, online survey assessed numeracy and risk perceptions including "feelings of risk" and a numerical estimate. RESULTS Regardless of numeracy, participants who received the enriched report had fewer overestimates of their lifetime risk estimate (LRE; odds ratio = 0.19, p < .001) and lower feelings of risk on two of three measures (p < .001). Participants with higher numeracy scores had fewer overestimates of LRE (OR = 0.66, p < .001) and lower feelings of risk on two out of three measures (p ≤ .01); the interaction between numeracy and report format was non-significant. CONCLUSION The enriched report produced more accurate LRE and lower risk perceptions regardless of numeracy level, suggesting the enriched format was helpful to individuals irrespective of numeracy ability. PRACTICE IMPLICATIONS Best practice elements in risk reports may help individuals form more accurate risk perceptions.

Abstract
Background The Arab population in Israel is a minority ethnic group with its own distinct cultural subgroups. Minority populations are known to underutilize genetic tests and counseling services, thereby undermining the effectiveness of these services among such populations. However, the general and culture-specific reasons for this underutilization are not well defined. Moreover, Arab populations and their key cultural-religious subsets (Muslims, Christians, and Druze) do not reside exclusively in Israel, but are rather found as a minority group in many European and North American countries. Therefore, focusing on the Arab population in Israel allows for the examination of attitudes regarding genetic testing and counseling among this globally important ethnic minority population. Methods We used a qualitative research method, employing individual interviews with 18 women of childbearing age from three religious subgroups (i.e., Druze, Muslim, and Christian) who reside in the Acre district, along with focus group discussions with healthcare providers (HCPs; 9 nurses and 7 genetic counselors) working in the same geographical district. Results A general lack of knowledge regarding the goals and practice of genetic counseling resulting in negative preconceptions of genetic testing was identified amongst all counselees. Counselors’ objective of respecting patient autonomy in decision-making, together with counselees’ misunderstanding of genetic risk data, caused uncertainty, frustration, and distrust. In addition, certain interesting variations were found between the different religious subgroups regarding their attitudes to genetic counseling. Conclusions The study highlights the miscommunications between HCPs, particularly counselors from the majority ethno-cultural group, and counselees from a minority ethno-cultural group. The need for nuanced understanding of the complex perspectives of minority ethno-cultural groups is also emphasized. Such an understanding may enhance the effectiveness of genetic testing and counseling among the Arab minority group while also genuinely empowering the personal autonomy of counselees from this minority group in Israel and other countries.

Abstract
Increasingly, patients without clinical indications are undergoing genomic tests. The purpose of this study was to assess their appreciation and comprehension of their test results and their clinicians' reactions. We conducted 675 surveys with participants from the Vanderbilt Electronic Medical Records and Genomics (eMERGE) cohort. We interviewed 36 participants: 19 had received positive results, and 17 were self-identified racial minorities. Eleven clinicians who had patients who had participated in eMERGE were interviewed. A further 21 of these clinicians completed surveys. Participants spontaneously admitted to understanding little or none of the information returned to them from the eMERGE study. However, they simultaneously said that they generally found testing to be "helpful," even when it did not inform their health care. Primary care physicians expressed discomfort in being asked to interpret the results for their patients and described it as an undue burden. Providing genetic testing to otherwise healthy patients raises a number of ethical issues that warrant serious consideration. Although our participants were enthusiastic about enrolling and receiving their results, they express a limited understanding of what the results mean for their health care. This fact, coupled the clinicians' concern, urges greater caution when educating and enrolling participants in clinically non-indicated testing.

Abstract
To establish the smallest change in genetic counseling outcome that is meaningful for patients, the aim of this study was to establish the Minimum Clinically Important Difference (MCID) for the Genetic Counseling Outcome Scale (GCOS-24). GCOS-24 is a patient-reported outcome measure for clinical genetics services. Secondary aims included understanding what patients deem important for reaching this score. Participants were 74 new patients recruited from the All Wales Medical Genetics Service, between April 2016 and December 2016. An anchor-based, global transition question methodology was used to identify the MCID, by asking participants how much meaningful change they experienced following their genetics appointment, and comparing this with GCOS-24 change scores. This ensured that the established score was clinically meaningful to patients. Comments from a free text response box were analyzed using qualitative thematic analysis. The mean score of the group who felt "a little better" was determined to be the MCID. The MCID was established to be a GCOS-24 score increase of 10.3 points after a clinical genetics appointment. This score was significantly different from the group "neutral" (0.64 points), using an independent samples t test. Themes identified as important for reaching the MCID included "future and family". These findings contribute to interpretability of GCOS-24 and provide some useful insights for genetic counseling service development.

Abstract
INTRODUCTION Genetic testing for hypertrophic cardiomyopathy (HCM) in the era of genomics brings unique challenges for genetic counselling. The number of genes routinely included in an HCM gene panel has increased markedly, many with minimal if any robust evidence of gene-disease association. Subsequently, there is a greater chance of uncertain genetic findings. The responsibility of communicating this information with at-risk relatives lies with the index case (proband). We have developed a communication aid to assist with the delivery of genetic results to the proband. We have previously shown the aid is feasible and acceptable and have now developed a study protocol for a randomised controlled trial of a genetic counsellor-led intervention incorporating the communication aid. METHODS AND ANALYSIS This is a prospective randomised controlled trial. We will investigate the impact of a genetic counsellor-led intervention to return proband genetic results using a custom-designed communication aid. We aim to improve knowledge and empowerment. The primary outcome of this trial is the ability and confidence of the proband to communicate genetic results to at-risk relatives. Secondary outcomes will assess genetic knowledge, satisfaction with services, outcomes from genetic counselling and psychological adaptation to genetic information. ETHICS AND DISSEMINATION This study has been approved by and is in strict accordance with the Sydney Local Health District Ethics Review Committee (X16-0030; 22/01/2016; version 1). Results from this trial will be prepared as a manuscript and submitted to peer-reviewed journals for publication as well as submission for presentation at national and international meetings. TRIAL REGISTRATION NUMBER ACTRN12617000706370.

Abstract
Psychosocial and behavioral outcomes of genetic testing in oncology are well known, however, it is unclear how these findings will generalize to more complex genomic testing. The aim of this systematic review was to assess the psychosocial and behavioral outcomes of cancer genomic testing. Studies were selected for inclusion if they were published from January 2003 to January 2017 and addressed psychological and behavioral outcomes of cancer genomic testing in adults. A review of four databases identified 9620 abstracts, with 22 publications meeting the inclusion criteria. Of the included articles, 11 studies reported on outcomes of germline testing, with three articles assessing panel testing and eight SNP testing. No studies assessed the outcomes of WGS or WES. Eleven articles assessed the outcomes of somatic testing, including testing for cancer prognosis and for personalized therapies. Studies were biased toward breast cancer and Caucasian women with high education and socioeconomic status. While studies demonstrated limited adverse psychological outcomes associated with genomic testing, a lack of consistency in psychosocial measures precluded any meta-analysis. Changes in health behavior following positive results were limited, and in some cases risk perception was not altered following genomic testing. There is limited evidence of adverse psychosocial outcomes and changes in health behavior following genomic testing to assess cancer risk. Findings from this review highlight the need for longitudinal research with superior methodological and theoretical design.

Abstract
PURPOSE Robust evidence about the value of clinical genomic interventions (CGIs), such as genetic/genomic testing or clinical genetic evaluation, is limited. We obtained stakeholders' perspectives on outcomes from CGIs to help inform their value. METHODS We used an adapted Delphi expert panel process. Two anonymous survey rounds assessed the value of 44 CGI outcomes and whether a third party should pay for them, with discussion in between rounds. RESULTS Sixty-six panelists responded to the first-round survey and 60 to the second. Policy-makers/payers gave the lowest ratings for value and researchers gave the highest. Patients/consumers had the most uncertainty about value and payment by a third party. Uncertainty about value was observed when evidence of proven health benefit was lacking, potential harms outweighed benefits for reproductive outcomes, and outcomes had only personal utility for individuals or family members. Agreement about outcomes for which a third party should not pay included prevention through surgery with unproven health benefits, establishing ancestry, parental consanguinity, and paternity. CONCLUSION Research is needed to understand factors contributing to uncertainty and stakeholder differences about the value of CGI outcomes. Reaching consensus will accelerate the creation of metrics to generate the evidence needed to inform value and guide policies that promote availability, uptake, and coverage of CGIs.

Abstract
With advances in breast cancer (BC) gene panel testing, risk counseling has become increasingly complex, potentially leading to unmet psychosocial needs. We assessed psychosocial needs and correlates in women initiating testing for high genetic BC risk in clinics in France and Germany, and compared these results with data from a literature review. Among the 442 counselees consecutively approached, 212 (83%) in France and 180 (97%) in Germany, mostly BC patients (81% and 92%, respectively), returned the ‘Psychosocial Assessment in Hereditary Cancer’ questionnaire. Based on the Breast and Ovarian Analysis of Disease Incidence and Carrier Estimation Algorithm (BOADICEA) BC risk estimation model, the mean BC lifetime risk estimates were 19% and 18% in France and Germany, respectively. In both countries, the most prevalent needs clustered around the “living with cancer” and “children-related issues” domains. In multivariate analyses, a higher number of psychosocial needs were significantly associated with younger age (b = −0.05), higher anxiety (b = 0.78), and having children (b = 1.51), but not with country, educational level, marital status, depression, or loss of a family member due to hereditary cancer. These results are in line with the literature review data. However, this review identified only seven studies that quantitatively addressed psychosocial needs in the BC genetic counseling setting. Current data lack understandings of how cancer risk counseling affects psychosocial needs, and improves patient-centered care in that setting.

Abstract
There has been very limited study of patients with chronic disease receiving potentially actionable genomic based results or the utilization of genetic counselors in the online result delivery process. We conducted a randomized controlled trial on 199 patients with chronic disease each receiving eight personalized and actionable complex disease reports online. Primary study aims were to assess the impact of in-person genomic counseling on 1) causal attribution of disease risk, 2) personal awareness of disease risk, and 3) perceived risk of developing a particular disease. Of 98 intervention arm participants (mean age = 57.8; 39% female) randomized for in-person genomic counseling, 76 (78%) were seen. In contrast, control arm participants (n = 101; mean age = 58.5; 54% female) were initially not offered genomic counseling as part of the study protocol but were able to access in-person genomic counseling, if they requested it, 3-months post viewing of at least one test report and post-completion of the study-specific follow-up survey. A total of 64 intervention arm and 59 control arm participants completed follow-up survey measures. We found that participants receiving in-person genomic counseling had enhanced objective understanding of the genetic variant risk contribution for multiple complex diseases. Genomic counseling was associated with lowered participant causal beliefs in genetic influence across all eight diseases, compared to control participants. Our findings also illustrate that for the majority of diseases under study, intervention arm participants believed they knew their genetic risk status better than control arm subjects. Disease risk was modified for the majority during genomic counseling, due to the assessment of more comprehensive family history. In conclusion, for patients receiving personalized and actionable genomic results through a web portal, genomic counseling enhanced their objective understanding of the genetic variant risk contribution to multiple common diseases. These results support the development of additional genomic counseling interventions to ensure a high level of patient comprehension and improve patient-centered health outcomes.

Abstract
BACKGROUND Procedural guidelines for disclosure of incidental genomic information are lacking. METHODS We introduce a method and evaluated the impact of returning results to population biobank participants with 16p11.2 copy number variants, which are commonly associated with neurodevelopmental disorders and BMI imbalance. Of the 7877 participants, 11 carriers were detected. Eight participants were informed of their carrier status and surveyed 11-17 months later. RESULTS All participants demonstrated preference for disclosure. Although two participants experienced worry, all five survey respondents rated receiving this information favorably. One participant reported modifications in treatment and three felt that their treatment/condition had since improved. CONCLUSION This approach can be adapted and applied for the return of incidental findings to biobank participants.

Abstract
BACKGROUND AND OBJECTIVE Having an inherited predisposition to cancer may have a psychological impact, and one goal of genetic counseling is to promote psychological adjustment to the new situation. Thus, in the genetic context, validated measures of adjustment are required. Given that self-concept is a good indicator of adjustment to the disease or to the risk for it, and a relevant variable in oncology, the goal of the study is to culturally adapt and validate the BRCA Self-Concept Scale. MATERIAL AND METHOD One hundred and sixty-five BRCA carriers' women answered to the questionnaire, previously adapted through a process of forward/back-translation, and to the Cancer Worry Scale (CWS) as a measure of convergent validity. Theoretical structure of BRCA Self-Concept Scale was assessed by expert judges, and submitted to a confirmatory factor analysis (CFA). Cronbach's α was calculated for each subscale (Stigma, Vulnerability and Control), and correlations with CWS were performed. RESULTS Expert judges' structure and CFA do not support the original structure of the questionnaire. The respecificity model (with items 10 and 13 loading on Vulnerability factor) show a better fit: comparative fit index 0.973; Tucker-Lewis index 0.968; root mean square error of approximation 0.067. The Cronbach's α is 0.83 for Stigma, 0.84 for Vulnerability, and 0.61 for Control. Evidence of convergent validity with CWS has been obtained (Spearman's rho 0.631 for Stigma, 0.683 for Vulnerability, and -0.363 for Control; P<.001). CONCLUSIONS Results support the validity of the modified Spanish BRCA Self-Concept Scale, which is a potentially useful measure for the study of psychological adjustment to high risk for hereditary breast and ovarian cancer.

Abstract
OBJECTIVE The serious mental illnesses schizophrenia, schizoaffective disorder, and bipolar disorder are complex conditions affecting 1% to 4% of the population. Individuals with serious mental illnesses express interest in genetic counseling, an intervention showing promise for increasing patient knowledge and adaptation. This trial aimed to evaluate the effects of genetic counseling for people with serious mental illnesses as compared to an educational intervention or wait list. METHOD A pilot 3-arm (each n = 40; genetic counseling, a control intervention involving an educational booklet, or wait list), parallel-group, randomized clinical trial was conducted from September 2008 through November 2011 in Vancouver, Canada. Participants with schizophrenia, bipolar disorder, or schizoaffective disorder (DSM-IV) completed outcome measures assessing knowledge, risk perception, internalized stigma, and perceived control over illness at baseline and 1-month follow-up. The Brief Symptom Inventory was administered to control for current symptoms. Analyses included linear mixed-effects models and χ(2) tests. RESULTS Knowledge increased for genetic counseling/educational booklet compared to wait list at follow-up (LRT1 = 19.33, Holm-adjusted P = .0003, R(2)LMM(m) = 0.17). Risk perception accuracy increased at follow-up for genetic counseling compared to wait list (Yates continuity corrected χ(2)1 = 9.1, Bonferroni P = .003) and educational booklet (Yates continuity corrected χ(2)1 = 8.2, Bonferroni P = .004). There were no significant differences between groups for stigma or perceived control scores. CONCLUSIONS Genetic counseling and the educational booklet improved knowledge, and genetic counseling, but not the educational booklet, improved risk perception accuracy for this population. The impact of genetic counseling on internalized stigma and perceived control is worth further investigation. Genetic counseling should be considered for patients with serious mental illnesses. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT00713804.

Abstract
Only a minority of individuals who undergo cancer genetic counseling experience heightened levels of psychological distress, but many more experience a range of cancer genetic-specific psychosocial problems. The aim of this study was to estimate the prevalence of such psychosocial problems, and to identify possible demographic and clinical variables associated significantly with them. Consenting individuals scheduled to undergo cancer genetic counseling completed the Psychosocial Aspects of Hereditary Cancer (PAHC) questionnaire, the Hospital Anxiety and Depression Scale (HADS) and the Distress Thermometer (DT) prior to or immediately following their counseling session. More than half of the 137 participants reported problems on three or more domains of the PAHC, most often in the domains 'living with cancer' (84%), 'family issues' (46%), 'hereditary predisposition' (45%), and 'child-related issues' (42%). Correlations between the PAHC, the HADS and the DT were low. Previous contact with a psychosocial worker, and having a personal history of cancer were associated significantly with HADS scores, but explained little variance (9%). No background variables were associated significantly with the DT. Previous contact with a psychosocial worker, and having children were significantly associated with several PAHC domains, again explaining only a small percentage of the variance (2-14%). The majority of counselees experience specific cancer genetic counseling-related psychosocial problems. Only a few background variables are associated significantly with distress or psychosocial problems. Thus we recommend using the PAHC or a similar problem-oriented questionnaire routinely in cancer genetic counseling to identify individuals with such problems.

Abstract
The need for evidence-based medicine, including comparative effectiveness studies and patient-centered outcomes research, has become a major healthcare focus. To date, a comprehensive list of genetic counseling outcomes, as espoused by genetic counselors, has not been established and thus, identification of outcomes unique to genetic counseling services has become a priority for the National Society of Genetic Counselors (NSGC). The purpose of this study was to take a critical first step at identifying a more comprehensive list of genetic counseling outcomes. This paper describes the results of a focus group study using the Reciprocal-Engagement Model (REM) as a framework to characterize patient-centered outcomes of genetic counseling clinical practice. Five focus groups were conducted with 27 peer nominated participants who were clinical genetic counselors, genetic counseling program directors, and/or outcomes researchers in genetic counseling. Members of each focus group were asked to identify genetic counseling outcomes for four to five of the 17 goals of the REM. A theory-driven, thematic analysis of focus group data yielded 194 genetic counseling outcomes across the 17 goals. Participants noted some concerns about how genetic counseling outcomes will be measured and evaluated given varying stakeholders and the long-term nature of genetic concerns. The present results provide a list of outcomes for use in future genetic counseling outcomes research and for empirically-supported clinical interventions.

Abstract
We describe the development and implementation of a randomized controlled trial to investigate the impact of genomic counseling on a cohort of patients with heart failure (HF) or hypertension (HTN), managed at a large academic medical center, the Ohio State University Wexner Medical Center (OSUWMC). Our study is built upon the existing Coriell Personalized Medicine Collaborative (CPMC®). OSUWMC patient participants with chronic disease (CD) receive eight actionable complex disease and one pharmacogenomic test report through the CPMC® web portal. Participants are randomized to either the in-person post-test genomic counseling—active arm, versus web-based only return of results—control arm. Study-specific surveys measure: (1) change in risk perception; (2) knowledge retention; (3) perceived personal control; (4) health behavior change; and, for the active arm (5), overall satisfaction with genomic counseling. This ongoing partnership has spurred creation of both infrastructure and procedures necessary for the implementation of genomics and genomic counseling in clinical care and clinical research. This included creation of a comprehensive informed consent document and processes for prospective return of actionable results for multiple complex diseases and pharmacogenomics (PGx) through a web portal, and integration of genomic data files and clinical decision support into an EPIC-based electronic medical record. We present this partnership, the infrastructure, genomic counseling approach, and the challenges that arose in the design and conduct of this ongoing trial to inform subsequent collaborative efforts and best genomic counseling practices.

Abstract
Genetic screening and health-care guidelines recommend that programmes should facilitate informed choice. It is therefore important that accurate measures of informed choice are available to evaluate such programmes. This review synthesises and appraises measures used to evaluate informed choice in population-based genetic screening programmes for reproductive risk. Databases were searched for studies offering genetic screening for the purpose of establishing reproductive risk to an adult population sample, in which aspects of informed choice were measured. Studies were included if, at a minimum, measures of uptake of screening and knowledge were used. Searches identified 1462 citations and 76 studies were reviewed in full text; 34 studies met the inclusion criteria. Over 20 different measures of informed choice were used. Many measures lacked adequate validity and reliability data. This systematic review will inform future evaluation of informed choice in population genetic screening programmes.

Abstract
The purpose of the study was to assess the counselee participation in the follow-up visits, compared to the first visits, for breast cancer genetic counselling and to explore associations with counselees' achievement of their preferred role in decision making, information recall, knowledge, risk perception alignment and perceived personal control. First and follow-up visits for breast cancer genetic counselling of 96 counselees of a Dutch genetics center were videotaped (2008-2010). Counselees completed questionnaires before counselling (T1), after the follow-up visit (T2) and one year after the follow-up visit (T3). Consultations were rated with the Roter Interaction Analysis System (RIAS). Counselee participation was measured as the percentage of counselee utterances, the percentage of counselee questions and the interactivity (number of turns per minute). Follow-up visits had higher levels of counselee participation than first visits as assessed by the percentage of counselee talk, the interactivity and counselee questions. More counselee talk in the follow-up visit was related to higher achievement of the preferred role (T2) and higher perceived personal control (T3). Higher interactivity in the follow-up visit was related to lower achievement of the preferred role in decision making and lower information recall (T2). There were no significant associations with the percentage of questions asked and none of the participation measures was related to knowledge, risk perception alignment and perceived personal control (T2). In line with the interviewing admonishment 'talk less and listen more', the only assessment of counselee participation associated to better outcomes is the percentage of counselee talk. High interactivity might be associated with lower recall in breast cancer genetic counselees who are generally highly educated. However, this study was limited by a small sample size and a heterogeneous group of counselees. Research is needed on the interactions causing interactivity and its relationships with involvement in decision making and recall.

Abstract
The routine use of genomic sequencing in clinical medicine has the potential to dramatically alter patient care and medical outcomes. To fully understand the psychosocial and behavioral impact of sequencing integration into clinical practice, it is imperative that we identify the factors that influence sequencing-related decision making and patient outcomes. In an effort to develop a collaborative and conceptually grounded approach to studying sequencing adoption, members of the National Human Genome Research Institute's Clinical Sequencing Exploratory Research Consortium formed the Outcomes and Measures Working Group. Here we highlight the priority areas of investigation and psychosocial and behavioral outcomes identified by the Working Group. We also review some of the anticipated challenges to measurement in social and behavioral research related to genomic sequencing; opportunities for instrument development; and the importance of qualitative, quantitative, and mixed-method approaches. This work represents the early, shared efforts of multiple research teams as we strive to understand individuals' experiences with genomic sequencing. The resulting body of knowledge will guide recommendations for the optimal use of sequencing in clinical practice.

Abstract
BACKGROUND Up to three-quarters of individuals who undergo cancer genetic counseling and testing report psychosocial problems specifically related to that setting. The objectives of this study were to develop and evaluate the screening properties of a questionnaire designed to assess specific psychosocial problems related to cancer genetic counseling. METHODS We adopted the European Organisation for Research and Treatment of Cancer Quality of Life Group guidelines to develop the Psychosocial Aspects of Hereditary Cancer (PAHC) questionnaire, a 26-item questionnaire organized into six problem domains: genetics, practical issues, family, living with cancer, emotions, and children. The Distress Thermometer and a question per domain on the perceived need for extra psychosocial services were included as well. We administered the questionnaire and the Hospital Anxiety and Depression Scale to 127 counselees at the time of genetic counseling and 3 weeks after DNA test disclosure. As a gold standard to evaluate the screening properties of the questionnaire, participants underwent a semi-structured interview with an experienced social worker who assessed the presence and severity of problems per domain. RESULTS A cutoff score representing responses of 'quite a bit' or 'very much' to one or more items within a given problem domain yielded moderate to high sensitivity across domains. A cutoff of 4 on the Distress Thermometer yielded high sensitivity. The questions regarding the perceived need for extra psychosocial services yielded high specificity and negative predictive values. CONCLUSION The Psychosocial Aspects of Hereditary Cancer questionnaire in combination with the Distress Thermometer can be used as a first-line screener for psychosocial problems within the cancer genetic counseling setting.

Abstract
BACKGROUND Myths and concerns about the extent and meaning of genetic risk in schizophrenia may contribute to significant stigma and burden for families. Genetic counseling has long been proposed to be a potentially informative and therapeutic intervention for schizophrenia. Surprisingly, however, available data are limited. We evaluated a contemporary genetic counseling protocol for use in a community mental health-care setting by non-genetics professionals. METHODS We used a pre-post study design with longitudinal follow-up to assess the impact of genetic counseling on family members of individuals with schizophrenia, where molecular testing had revealed no known clinically relevant genetic risk variant. We assessed the outcome using multiple measures, including standard items and scales used to evaluate genetic counseling for other complex diseases. RESULTS Of the 122 family members approached, 78 (63.9%) actively expressed an interest in the study. Participants (n = 52) on average overestimated the risk of familial recurrence at baseline, and demonstrated a significant improvement in this estimate postintervention (P < .0001). This change was associated with an enduring decrease in concern about recurrence (P = .0003). Significant and lasting benefits were observed in other key areas, including increased knowledge (P < .0001) and a decreased sense of stigma (P = .0047). Endorsement of the need for genetic counseling was high (96.1%). CONCLUSIONS These results provide initial evidence of the efficacy of schizophrenia genetic counseling for families, even in the absence of individually relevant genetic test results or professional genetics services. The findings support the integration of contemporary genetic counseling for families into the general management of schizophrenia in the community.

Abstract
Approximately 25% of individuals undergoing genetic counseling for cancer experiences clinically relevant levels of distress, anxiety and/or depression. However, these general psychological outcomes that are used in many studies do not provide detailed information on the specific psychosocial problems experienced by counselees. The aim of this review was to investigate the specific psychosocial issues encountered by individuals undergoing genetic counseling for cancer, and to identify overarching themes across these issues. A literature search was performed, using four electronic databases (PubMed, PsychInfo, CINAHL and Embase). Papers published between January 2000 and January 2013 were selected using combinations, and related indexing terms of the keywords: 'genetic counseling', 'psychology' and 'cancer'. In total, 25 articles met our inclusion criteria. We identified the specific issues addressed by these papers, and used meta-ethnography to identify the following six overarching themes: coping with cancer risk, practical issues, family issues, children-related issues, living with cancer, and emotions. A large overlap in the specific issues and themes was found between these studies, suggesting that research on specific psychosocial problems within genetic counseling has reached a point of saturation. As a next step, efforts should be made to detect and monitor these problems of counselees at an early stage within the genetic counseling process.

Abstract
Genetic counseling can result in better outcomes when clients understand what to expect, and at least theoretically, at some point in their lifespan, anyone could be referred for or benefit from genetic counseling. Thus, in order to identify (and ultimately address) issues around awareness of genetic counseling and perceptions of its purpose, we surveyed the Canadian general population. We acquired 1,000 telephone numbers corresponding to a demographically representative sample of Canada from Survey Sampling International, and invited individuals to participate in a telephone-based survey. We administered a purpose-designed survey (in either French or English) comprising questions regarding: demographics, whether or not the individual had heard of genetic counseling, and 15 Likert scale-rated (strongly disagree-strongly agree) items about the possible purposes of genetic counseling. Responses to these 15 items were used to generate a total "knowledge score". Of the 1,000 numbers, n = 372 could not be reached, and the survey was successfully administered to n = 188 individuals (response rate 30 %). Most respondents (n = 129, 69 %) had not heard of genetic counseling, and substantial proportions thought that genetic counseling aims to prevent genetic diseases and abnormalities, help couples have children with desirable characteristics, and help people to understand their ancestry. These data could be used to inform the strategy for development of future awareness efforts, and as a baseline from which to measure their effects.

Abstract
Down syndrome occurs in approximately 1:600 live births. Genetic counseling is indicated for these families and may be beneficial for adaptation to the challenges that accompany by this diagnosis. Although the basic counseling goals are similar, there are many models of genetic counseling practiced around the world. The aim of this article is to report the results of a pilot study that evaluated the level of satisfaction with a model of service delivery of genetic counseling practiced in Brazil, the knowledge assimilated about Down syndrome and whether this process resulted in a feeling of well-being and psychological support. Thirty mothers of under 6-month-old children with Down syndrome were interviewed after having two sessions of genetic counseling in a public healthcare service within a period of 30 days. A semi-structured questionnaire was developed by the researchers to collect identification, socioeconomic and demographic data and to assess the client's satisfaction with the model of genetic counseling. Data were collected using both open and closed questions. The reported level of satisfaction was high. The knowledge assimilated about Down syndrome after only two sessions was considered technically vague by raters in 44 % of cases. Most mothers (96.7 %) reported that genetic counseling was beneficial and provided psychological support. The model was considered satisfactory, but further research is needed to identify ways to improve knowledge retention by this population. These results highlight the utility of referring families for genetic counseling when there is a suspicion of a diagnosis of Down syndrome.

Abstract
Limited data suggest that enhanced self-knowledge from genetic information related to non-medical traits can have a positive impact on psychological well-being. Deaf individuals undertake genetic testing for deaf genes to increase self-knowledge. Because deafness is considered a non-medical trait by many individuals, we hypothesized that deaf individuals receiving a genetic explanation for why they are deaf will experience increased psychological well-being. We report results from a prospective, longitudinal study to determine the impact of genetic testing (GJB2, Cx26; GJB6, Cx30) on perceived personal control (PPC), anxiety, and depression in deaf adults (N = 209) assessed following pre-test genetic counseling as well as 1-month and 6-months following test result disclosure. Participants were classified as Cx positive (n = 82) or Cx negative/inconclusive (n = 127). There was significant evidence for Cx group differences in PPC and anxiety over time (PPC: Cx group*time interaction p = 0.0007; anxiety: Cx group*time interaction p = 0.002), where PPC scores were significantly higher, and anxiety scores were significantly lower for the Cx positive group relative to the negative/inconclusive group following test result disclosure. Compared to pre-test, PPC scores increased at 1-month (p = 0.07) and anxiety scores decreased at 6-months (p = 0.03) for the Cx positive group. In contrast, PPC scores decreased (p = 0.009, p < 0.0001) and anxiety scores increased (p = 0.09, p = 0.02) for the Cx negative/inconclusive group at 1- and 6-months post test result disclosure. Genetic testing for deaf genes affects the psychological well-being of deaf individuals. Increasing deaf adults' access to genetic testing may potentially enhance self-knowledge and increase psychological well-being for those who receive a genetic explanation, which could offer downstream health benefits.

Abstract
The Genetic and Endoscopic Surveillance Clinic is an annual outreach service offering accessible colonoscopic surveillance to known families with Lynch syndrome living in remote areas of the Western and Northern Cape Province of South Africa. Unfortunately attendance at this outreach clinic has been declining over several years and fewer than a quarter of participants, attending for surveillance, have been adherent with all their recommended screening appointments. Concerns exist for non-adherent individuals as screening can prevent colorectal cancer by removing the precancerous lesion or enabling the treatment of a malignancy at an early stage. This study explored the experience of surveillance from both the non-adherers' and adherers' perspectives and identified unique factors affecting attendance at the outreach clinic. Rates of compliance are calculated for 191 mutation-positive cases of Lynch syndrome, using strict attendance criteria, and compared to figures obtained from self-reported attendance. Non-compliance was under-reported and compliance was exaggerated when basing data on self-reported adherence to recommendations. Specific characteristics of the outreach clinic affecting compliance are identified and recommendations are made to facilitate improvements to the service. These improvements can result in increased compliance with screening regimens and ultimately reduce cancer-related mortality.

Abstract
Advances in genetic epidemiology have increased understanding of common, polygenic preventable diseases such as type 2 diabetes. As genetic risk testing based on this knowledge moves into clinical practice, we propose that genetic counselors will need to expand their roles and adapt traditional counseling techniques for this new patient set. In this paper, we present a genetic counseling intervention developed for a clinical trial [Genetic Counseling/Lifestyle Change for Diabetes Prevention, ClinicalTrials.gov identifier: NCT01034319] designed to motivate behavioral changes for diabetes prevention. Seventy-two phenotypically high-risk participants received counseling that included their diabetes genetic risk score, general education about diabetes risk factors, and encouragement to participate in a diabetes prevention program. Using two validated genetic counseling scales, participants reported favorable perceived control and satisfaction with the counseling session. Our intervention represents one model for applying traditional genetic counseling principles to risk testing for polygenetic, preventable diseases, such as type 2 diabetes.

Abstract
PURPOSE Videoconferencing is increasingly used to deliver family cancer services for hereditary breast and ovarian cancer to outreach areas. This study compared the effectiveness and acceptability of genetic counseling for hereditary breast and ovarian cancer through videoconferencing (hereafter referred to as "telegenetics"). METHODS One hundred six women seen by telegenetics and 89 women seen face-to-face completed self-administered questionnaires before, and 1 month after, genetic counseling. Telegenetics consultations involved a genetic clinician via telegenetics in addition to a local genetic counselor present with the patient. RESULTS No significant differences were found between telegenetics and face-to-face genetic counseling in terms of knowledge gained (P = 0.55), satisfaction with the genetic counseling service (P = 0.76), cancer-specific anxiety (P = 0.13), generalized anxiety (P = 0.42), depression (P = 0.96), perceived empathy of the genetic clinician (P = 0.13), and perceived empathy of the genetic counselor (P = 0.12). Telegenetics performed significantly better than face-to-face counseling in meeting patients' expectations (P = 0.009) and promoting perceived personal control (P = 0.031). CONCLUSION Telegenetics seems to be an acceptable and effective method of delivering genetic counseling services for hereditary breast and ovarian cancer to underserved areas.

Exploring the short-term impact of DNA-testing in breast cancer patients: the counselees' perception matters, but the actual BRCA1/2 result does not. PATIENT EDUCATION AND COUNSELING 2012; 86:239-251. [PMID: 21684708 DOI: 10.1016/j.pec.2011.04.017] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/02/2010] [Revised: 03/11/2011] [Accepted: 04/08/2011] [Indexed: 05/30/2023]
Abstract
OBJECTIVE Previous studies suggest that learning a DNA-test-result has no direct impact on the medical-decisions and psychological well-being of counselees. Their perception, especially their recollections and interpretations of their cancer-risks and heredity, predict and/or mediate this impact. These studies were criticized for their small range of predictors, mediators, outcomes and contextual factors. We studied the short-term impact of DNA-testing with an extended model. METHODS Three months after disclosure of BRCA1/2-test-results, we sent counselees a questionnaire about their perception, medical and psychological outcomes, and medical, familial and psychological contexts. 248 affected women participated; 30 had received pathogenic-mutations, 16 unclassified-variants and 202 uninformative-results. RESULTS The actually communicated genetic-information and the contextual variables predicted the counselees' perception, but did not directly predict any outcomes. The counselees' perception predicted and/or completely mediated the counselees' medical intentions and behavior, physical and psychological life-changes, stigma, mastery, negativity and cancer-worries. Short-term distress was related to the perception not only of their own risks, but also of their relatives' risks and heredity-likelihood. Effect sizes were medium to large. CONCLUSIONS AND IMPLICATIONS The outcomes of DNA-testing were better predicted by the counselees' perception than by the actually given genetic-information. We recommend genetic-counselors to have tailored, interactive dialogues about the counselees' perception.

Abstract
PURPOSE Little is known about the long-term impact of BRCA1/2 testing on the relationships between family members. We assessed the incidence of positive and negative family relationship effects of BRCA1/2 testing in the 3 years after result disclosure and identified predictors of these effects. METHODS A total of 485 women and 67 men who had undergone BRCA1/2 testing were asked 3 years later whether having been tested had improved and/or disrupted relationships with their relatives. The associations with sociodemographic, medical, and psychosocial characteristics were assessed. RESULTS Globally, 85.1% did not report any positive or negative effects of genetic testing on family relationships. Positive and negative effects were reported by 13.2% and 3.7% of participants, respectively. Reporting positive relationship effects was associated with older age, intolerance for uncertainty, cancer-specific distress, and more social support. Low education, positive attitude toward prophylactic mastectomy, and low social support increased the likelihood of negative effects. CONCLUSION Our findings do not support the belief that family relationships are frequently disrupted by BRCA1/2 testing. Understanding that most family relationships are unchanged long term by genetic testing may help genetic service providers encourage those considering testing to overcome hesitancy related to potential difficulties of communicating results to relatives.

Abstract
Presymptomatic testing (PST) is available for a range of late-onset disorders. Health practitioners generally follow guidelines regarding appropriate number of counseling sessions, involvement of multidisciplinary teams, topics for pretest discussion, and follow-up sessions; however, more understanding is needed about what helps consultands effectively and the impact of amount and quality of genetic counseling on the psychosocial sequelae of PST for late-onset disorders. We conducted a thematic analysis of three review articles on quality of the genetic counseling process, aiming at (1) exploring current evidence; (2) identifying quality assessment indicators; and (3) making recommendations for genetic counseling practice in late-onset disorders. We undertook a systematic search of 6 relevant databases: 38 articles were identified and 3 fitted our inclusion criteria; after quality appraisal, all were included in the review. The number of sessions, time spent, consultation environment, follow-up, and multidisciplinarity were identified as variables for quality assessment. Research on counseling in the context of genetic testing in familial cancer tends to be related to outcomes and indicators for quality assessment, while research concerning other late-onset diseases is mainly focused on the psychological impact of the test results. The quality and content of the overall process in noncancer late-onset diseases is insufficiently articulated. Despite the fact that PST for Huntington disease and other degenerative conditions has been offered for more than 20 years, good methodological approaches to assess quality of genetic counseling in that context remain elusive. This restricts improvement of the protocols for genetic services and, in general, healthcare for the at-risk population.

Abstract
OBJECTIVE To assess a genetic counseling intervention measuring the distress, cancer risk perception, anxiety, worry and level of knowledge in people with familial history of breast cancer. METHODS One group pre- and post-test design. A total of 212 individuals completed a baseline questionnaire, 88.6% completed a second questionnaire one month later and 75.4% six months later. RESULTS Counseling intervention significantly increased the knowledge level of the individuals who received genetic education and significantly decreased the cancer worry levels. Persons with low perception of their cancer risk also had low worry levels. There were no significant changes over time in cancer risk perception or in quality of life. CONCLUSION Counseling in a high risk population seems to decrease cancer worry and to increase cancer knowledge thus enabling a counselee to take well-informed decisions. Furthermore, according to our results, such interventions do not increase anxiety and do not modify the quality of life, but do not adjust their cancer risk perception. PRACTICE IMPLICATIONS Providing individuals at increased risk of breast cancer genetic services seem to enhance their understanding of breast cancer without causing adverse psychological effects or changes in their quality of life, and it could improve their preventive behaviours.
