Wells I, Zemedikun DT, Simons G, Stack RJ, Mallen CD, Raza K, Falahee M. Predictors of the likelihood that patients with rheumatoid arthritis will communicate information about rheumatoid arthritis risk to relatives: A quantitative assessment. PATIENT EDUCATION AND COUNSELING 2023; 112:107713. [PMID: 37003160 DOI: 10.1016/j.pec.2023.107713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 02/10/2023] [Accepted: 03/17/2023] [Indexed: 05/09/2023]
Abstract
First-degree relatives (FDRs) of people with rheumatoid arthritis (RA) are increasingly recruited to prediction and prevention studies. Access to FDRs is usually via their proband with RA. Quantitative data on predictors of family risk communication are lacking. RA patients completed a questionnaire assessing likelihood of communicating RA risk information to their FDRs, demographic variables, disease impact, illness perceptions, autonomy preferences, interest in FDRs taking a predictive test for RA, dispositional openness, family functioning, and attitudes towards predictive testing. Ordinal regression examined associations between patients' characteristics and their median likelihood of communicating RA risk to FDRs. Questionnaires were completed by 482 patients. The majority (75.1%) were likely/extremely likely to communicate RA risk information to FDRs, especially their children. Decision-making preferences, interest in FDRs taking a predictive test, and beliefs that risk knowledge would increase people's empowerment over their health increased patients' odds of being likely to communicate RA risk information to FDRs. Beliefs that risk information would cause stress to their relatives decreased odds that patients would be likely to communicate RA risk. These findings will inform the development of resources to support family communication about RA risk.

Patient and Relative Experiences and Decision-making About Genetic Testing and Counseling for Familial ALS and FTD: A Systematic Scoping Review. Alzheimer Dis Assoc Disord 2021; 35:374-385.

Abstract
Genetic testing and counseling is an emerging part of care for patients with amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) and their families. This scoping review aimed to map patients' and relatives' experiences of genetic testing and counseling for familial ALS and FTD and the factors influencing their decision to proceed with testing or counseling. Informed by the Joanna Briggs Institute methodology, 5 databases were systematically searched. Thirty studies from 39 references were included. A descriptive numerical summary analysis and narrative synthesis was conducted. Mostly positive diagnostic testing experiences were reported, but issues arose due to progressive disease and discordant results. Predictive testing impacted at-risk relatives, regardless of the result received, and psychosocial sequelae ranged from relief to guilt, worry or contemplating suicide. Four reproductive testing experiences were reported. Personal, familial and practical factors, and the lived experience of disease, informed decision-making. Greater uncertainty and complexity may be faced in familial ALS/FTD than in other late-onset neurodegenerative diseases due to clinical and genetic heterogeneity, and testing limitations. Genetic counseling models of care should consider this difference to ensure that individuals with, or at risk of, ALS/FTD are effectively managed. Implications for research and practice are discussed.

Abstract
Genetic diseases are a family matter, requiring adjustment and management from the family system, particularly when the diagnosis is recent. Literature has evidenced the importance of the role of older relatives in families dealing with some genetic diseases; however, knowledge is scarce regarding rare incurable genetic disorders, such as Huntington disease. Therefore, this exploratory qualitative study aims at describing how adjustment to Huntington disease occurs, from a family perspective, considering the roles performed by older generations, in the Portuguese context. It adopts the critical incidents technique, administered based on semi-structured interviews, and comprises 10 participants, aged 28 to 72 years (8 females), from seven families. Participants reported 130 critical incidents. The interviews were audiotaped, transcribed, and submitted to thematic analysis. Findings portray participants and their families as "beginners" in understanding and incorporating Huntington disease in their lives, due to recent diagnosis. In addition, data suggest that older relatives play two relevant roles in the creation of family narratives: (1) "shaping awareness about HD" (68 critical incidents) and (2) "influencing HD management" (62 critical incidents). Genetic counseling and family-centered interventions aimed at supporting families with a history of hereditary genetic diseases, should consider a narrative approach involving older relatives, since they have a great influence in sustaining family stories.

Abstract
The American Academy of Pediatrics, the American College of Medical Genetics and Genomics, and the American Academy of Neurology recommend genetic testing, as a genetic evaluation tool, for children diagnosed with autism spectrum disorders (ASD). Despite the potential benefits, the utilization of genetic testing is low. We proposed an integrated theoretical framework to examine parents' intention and associated psychosocial factors in pursuing genetic testing for their children with ASD. Recruiting primarily from the Interactive Autism Network, a nationwide sample of 411 parents of children with ASD who had never pursued genetic testing for their children completed our theory-based online survey. Data were analyzed using structural equation modeling. About half of the parents were willing to pursue genetic testing for their children with ASD. Findings of the structural equation modeling suggested a good model fit between our integrated theoretical framework and survey data. Parents' intention was significantly and positively associated with their attitudes toward genetic testing, subjective norm, and self-efficacy in having their children tested. This study serves as an initial window to understand parental intention to pursue genetic testing for their children with ASD. Our findings can help physicians and genetic counselors understand, educate, counsel, and support parents' decision-making about having their children with ASD genetically tested. Furthermore, our study can also assist physicians and genetic counselors in developing theory- and evidence-based patient education materials to enhance genetic testing knowledge among parents of children with ASD.

Abstract
Unaffected relatives of individuals with Lynch syndrome can be offered predictive genetic testing to guide surveillance recommendations. The decision-making process of those who decline testing, particularly those who do not attend a clinical genetics service, is poorly understood. We have addressed this gap by interviewing 33 individuals from Lynch syndrome mutation-carrying families, unaffected by cancer, who declined predictive genetic testing. Here, we analyse the data provided by 20 participants who unequivocally declined testing. Those who indicated they did not have enough information to make a decision or intended to undergo testing in the future were excluded. Analysis revealed that few decliners discussed their decision with general practitioners or genetic counsellors. Family members were commonly involved to varying degrees, with participants either (1) making group decisions with family members, (2) feeling persuaded by family members to either accept or decline testing, (3) discussing the test but making their own decision. A minority did not discuss testing with family members while making their decision. This research reveals the health communication activities of an understudied group, those declining predictive testing, and indicates that for many, health professionals play a minor role in the decision compared to family.

Abstract
Cascade screening is the process of contacting relatives of people who have been diagnosed with certain hereditary conditions. Its purpose is to identify, inform, and manage those who are also at risk. We conducted a scoping review to obtain a broad overview of cascade screening interventions, facilitators and barriers to their use, relevant policy considerations, and future research needs. We searched for relevant peer-reviewed literature in the period 1990-2017 and reviewed 122 studies. Finally, we described 45 statutes and regulations related to the use and release of genetic information across the fifty states. We sought standardized best practices for optimizing cascade screening across various geographic and policy contexts, but we found none. Studies in which trained providers contacted relatives directly, rather than through probands (index patients), showed greater cascade screening uptake; however, policies in some states might limit this approach. Major barriers to cascade screening delivery include suboptimal communication between the proband and family and geographic barriers to obtaining genetic services. Few US studies examined interventions for cascade screening or used rigorous study designs such as randomized controlled trials. Moving forward, there remains an urgent need to conduct rigorous intervention studies on cascade screening in diverse US populations, while accounting for state policy considerations.

Abstract
Background The search for essential tremor (ET) genes is active, and it is only a matter of time before genetic tests become available. Genetic testing preferences in families have been studied in numerous other neurological disorders but there are no published data about ET. Methods We surveyed 34 ET probands and their relatives (43 affected, 28 unaffected) enrolled in our Family Study of Essential Tremor to assess their interest in genetic testing. We examined whether clinical factors influenced their interest in testing. Clinical utility (“Your physician will be able to use the information obtained to improve your care”) and penetrance (“How likely an individual who carries an ET gene is to develop ET”) were defined for participants. Results Interest in genetic testing was high in ET families (90/105 [85.7%]). There was a significant difference between affected (including probands and affected relatives) and unaffected relatives in terms of their interest in genetic testing, with the former being more interested (70/77 [90.9%] vs. 20/28 [71.4%] p = 0.04). Participants were more likely to want testing in the scenarios with high clinical utility; disease penetrance was not a determining factor (all p < 0.05). Sixteen hypothetical factors were identified that might influence a participant’s decision to undergo genetic testing for ET. Discussion Interest in genetic testing was high in ET families. While genetic testing is not currently available for ET, the hunt for ET genes is ongoing, and this is a highly familial disorder. Understanding genetic testing preferences will greatly aid clinicians once a genetic test becomes available.

Abstract
This manuscript describes the ways in which genetic counseling has evolved since John Pearson and Sheldon Reed first promoted "a genetic education" in the 1950s as a voluntary, non-directive clinical tool for permitting individual decision making. It reviews how the emergence of Huntington's disease (HD) registries and patient support organizations, genetic testing, and the discovery of a disease-causing CAG repeat expansion changed the contours of genetic counseling for families with HD. It also reviews the guidelines, outcomes, ethical and laboratory challenges, and uptake of predictive, prenatal, and preimplantation testing, and it casts a vision for how clinicians can better make use of genetic counseling to reach a broader pool of families that may be affected by HD and to ensure that genetic counseling is associated with the best levels of care. © 2016 Wiley Periodicals, Inc.

Abstract
Little is known about the process of psychosocial adaptation to familial risk in tested and untested individuals at increased familial risk of cancer. This paper presents findings from a qualitative study of 36 women participating in the Kathleen Cuningham Consortium for Research into Familial Breast cancer (kConFab) Psychosocial study. Facilitators and challenges in psychosocial adaptation were identified through semi-structured interviews. The women, who were either tested (carriers or non-carriers of breast cancer susceptibility mutations) or untested (ineligible for testing or eligible but delayed or declined testing), described personal, support network and healthcare characteristics that impacted on the adaptation process. Challenges in one domain could be overcome by facilitators in other domains and key differences relating to whether women had undergone testing, or not, were identified. Tested and untested women with an increased familial risk of breast cancer may benefit from support tailored to their mutation testing status in order to enhance adaptation.

Abstract
Genetic testing is increasingly available in medical settings and direct-to-consumer. However, the large and growing literature on genetic testing decisions is rife with conflicting findings, inconsistent methodology, and uneven attention across test types and across predictors of genetic testing decisions. Existing reviews of the literature draw broad conclusions but sacrifice nuanced analysis that with a closer look reveals far more inconsistency than homogeny across studies. The goals of this paper are to provide a systematic review of the empirical work on predictors of genetic testing decisions, highlight areas of consistency and inconsistency, and suggest productive directions for future research. We included all studies that provided quantitative analysis of subjective (e.g., perceived risk, perceived benefits of testing) and/or objective (e.g., family history, sociodemographic variables) predictors of genetic testing interest, intentions, or uptake, which produced a sample of 115 studies. From this review, we conclude that self-reported and test-related (as opposed to disorder-related or objective) predictors are relatively consistent across studies but that theoretically-driven efforts to examine testing interest across test types are sorely needed.

Abstract
Many questions remain concerning whether, when, and how physicians order genetic tests, and what factors are involved in their decisions. We surveyed 220 internists from two academic medical centers about their utilization of genetic testing. Rates of genetic utilizations varied widely by disease. Respondents were most likely to have ordered tests for Factor V Leiden (16.8 %), followed by Breast/Ovarian Cancer (15.0 %). In the past 6 months, 65 % had counseled patients on genetic issues, 44 % had ordered genetic tests, 38.5 % had referred patients to a genetic counselor or geneticist, and 27.5 % had received ads from commercial labs for genetic testing. Only 4.5 % had tried to hide or disguise genetic information, and <2 % have had patients report genetic discrimination. Only 53.4 % knew of a geneticist/genetic counselor to whom to refer patients. Most rated their knowledge as very/somewhat poor concerning genetics (73.7 %) and guidelines for genetic testing (87.1 %). Most felt needs for more training on when to order tests (79 %), and how to counsel patients (82 %), interpret results (77.3 %), and maintain privacy (80.6 %). Physicians were more likely to have ordered a genetic test if patients inquired about genetic testing (p < .001), and if physicians had a geneticist/genetic counselor to whom to refer patients (p < .002), had referred patients to a geneticist/genetic counselor in the past 6 months, had more comfort counseling patients about testing (p < .019), counseled patients about genetics, larger practices (p < .032), fewer African-American patients (p < .027), and patients who had reported genetic discrimination (p < .044). In a multiple logistic regression, ordering a genetic test was associated with patients inquiring about testing, having referred patients to a geneticist/genetic counselor and knowing how to order tests. These data suggest that physicians recognize their knowledge deficits, and are interested in training. These findings have important implications for future medical practice, research, and education.

Abstract
The aim of this study was to describe the experiences of undergoing a presymptomatic genetic test for the hereditary and fatal Huntington’s disease, using a case study approach. The study was based on 18 interviews with a young woman and her husband from the decision to undergo the test, to receiving the results and trying to adapt to them, which were analysed using a life history approach. The findings show that the process of undergoing a presymptomatic test involves several closely connected ethical and medical questions, such as the reason for the test, the consequences of the test results and how health-care services can be developed to support people in this situation.

Abstract
Patient background, needs, and expectations (BNE) can be important predictors and modifiers of the process and outcomes of genetic counseling. We describe the assessment of BNE of 216 genetic counseling clients using the BNE Scale. Twenty-five percent sought reproductive genetic counseling (RGC), 57% sought adult-pediatric genetic counseling (APGC), and 18% sought cancer genetic counseling (CaGC). Analyses of the BNE of these patient groups identified significant differences in general unsureness/uncertainty about their condition (df = 2, F = 3.96, Significance =0.02), beliefs about treatment for the condition (d f= 2, F = 3.352, Significance = 0.04), and interest in support group involvement (df = 2, F =4.6, Significance = 0.01). Respondents who had not had genetic counseling more readily endorsed the desire to address educational issues than those who had previously had genetic counseling (Previous GC: Mean = 4.03, SD = 0.67; No Previous GC: Mean = 4.29, SD = 0.61; t-value; -2.86; P < 0.01). These results suggest that there are significant differences in the BNE of groups of patients seeking genetic counseling. These data support differential genetic counseling goal setting based on practice subspecialty, as well as sustain the requirement of broad based clinical training in genetic counseling. Further, these data provide additional evidence of the reliability and validity of the BNE Scale to characterize groups of individuals eligible for genetic counseling.

Abstract
The recent advent of commercially available genetic tests for the diagnosis of several mental illnesses has led to intense controversy amongst the psychiatric research community. In this article the authors review these developments, and contrast these with the growing evidence from genomewide association studies that highly heritable psychiatric conditions such as schizophrenia are due to the contributions and interaction of multiple allelic variants, each of small effect size. There is also evidence for the contribution of some highly penetrant rare de novo copy number variants, though the lack of disease specificity for these is of concern. This article outlines the prerequisites for predictive and diagnostic genetic tests, such as clinical validity and utility, and reviews the opportunity that genetic tests for mental illnesses present. As the scientific discourse on genetic tests for complex disorders is not limited to psychiatry, the authors outline current thoughts on the significance of genome-wide association studies across health, and the phenomenon of direct-to-consumer tests in medicine. The attitudes and understanding of patients, families, and clinicians about the future (currently hypothetical) scenario of psychiatric genetic tests are discussed, as is the potential for such testing to increase, rather than diminish stigma. Finally, recommendations on the future development and availability of genetic tests in psychiatry are provided.

Abstract
Critical questions arise about misunderstandings of genetics. We interviewed for 2 h each, 64 individuals who had or were at risk for Huntington's disease (HD), breast cancer or Alpha-1 antitrypsin deficiency. These individuals revealed various misunderstandings that can affect coping, and testing, treatment and reproductive decisions. A therapeutic misconception about testing appeared: that testing would be helpful in and of itself. Many believed they could control genetic disorders (even HD), yet these beliefs were often incorrect, and could impede coping, testing, and treatment. Misunderstandings about statistics and genetics often fueled each other, and reflected denial, and desires for hope and control. Emotional needs can thus outweigh understandings of genetics and statistics, and providers' input. Individuals often maintained non-scientific beliefs, though embarrassed by these. These data have implications for care, and public and professional education. Misunderstandings' persistence, despite realization of their inaccuracy, suggests that providers need to address not just cognitive facts, but underlying emotional issues.

Abstract
Though the US passed the Genetic Information Non-Discrimination Act, many questions remain of how individuals confronting genetic disease view and experience possible discrimination. We interviewed, for 2 hours each, 64 individuals who had, or were at risk for, Huntington's Disease, breast cancer, or Alpha-1 antitrypsin deficiency. Discrimination can be implicit, indirect and subtle, rather than explicit, direct and overt; and be hard to prove. Patients may be treated "differently" and unfairly, raising questions of how to define "discrimination", and "appropriate accommodation". Patients were often unclear and wary about legislation. Fears and experiences of discrimination can shape testing, treatment, and disclosure. Discrimination can be subjective, and take various forms. Searches for only objective evidence of it may be inherently difficult. Providers need to be aware of, and prepared to address, subtle and indirect discrimination; ambiguities, confusion and potential limitations concerning current legislation; and needs for education about these laws. Policies are needed to prevent discrimination in life, long-term care, and disability insurance, not covered by GINA.

Abstract
Many, women who have, or are at risk for, BRCA, 1/2 mutations or breast cancer decline prophylactic surgery, but questions remain as to how they make and experience these decisions. Our methods consisted of interviewing 32 women for 2 hr each; 19 were tested, 20 were symptomatic. Our results showed that these surgical options forced women to confront questions, involving stresses and uncertainties, regarding: implications of test results, prognoses with and without surgery, and effects of surgery (e.g., on self-image). Given these dilemmas, many women turned to doctors who then ranged in what and how they communicated about these issues, and how strongly they offered input. Some patients felt disappointed at provider non-directiveness, while others found providers too directive. Patients turned to family members and friends, who also ranged in how and what they communicated, and whether they agreed with the patient and/or each other. Many women turned to patient communities, but then had to decide how involved to be, and what information to provide or accept. These data suggest that providers and others may need to be more aware of the series of questions, involving stresses and uncertainties, that these women face, and the complex roles providers themselves may play. These data highlight needs for physicians to be able to address these issues flexibly, gauging patient preferences for information and paternalism (vs. autonomy). These data suggest areas for future research: for example, on how providers decide whether, what and how to communicate about these issues, and how these choices shape treatment decisions.

Abstract
Research indicates that health care professionals' attitudes may affect patients' decisions regarding prenatal Huntington Disease testing, but few studies have sampled genetic counselors. In this qualitative study, genetic counselors described their experiences counseling individuals at risk for HD regarding reproductive decision-making. Five major research questions were investigated: 1) What are genetic counselor responsibilities? 2) What issues arise for patients and counselors? 3) How do counselors reconcile prenatal testing with presymptomatic testing? 4) To what extent are counselors' initial expectations of at-risk patients' beliefs and behaviors met? and 5) What advice would counselors offer to novice practitioners about working with this patient population? Fifteen genetic counselors experienced in counseling individuals at risk for HD participated in a semi-structured phone interview that yielded several themes. For example, participants identified their primary responsibility as information provision; less prevalent were psychosocial support and facilitating decision making. The most common ethical challenge was testing prenatally for HD which also results in presymptomatic testing of minors. Participants were divided about how directive to be in response to this ethical issue and about termination of a gene positive pregnancy.

Abstract
AIMS To elucidate psychosocial and ethical issues faced by adults at risk for alpha-1 antitrypsin deficiency (AATD) that have received little attention. METHODS Eleven individuals with AATD were interviewed in detail for 2 hours each. RESULTS Several specific aspects of AATD created critical, socially dynamic issues that shaped the patients' responses. The disease being relatively newly discovered, physicians do not know much about it and thus often do not consider or recommend testing for it. Hence, patients who may benefit from diagnosis and treatment are not always diagnosed. General practitioners, when they do diagnose patients, often refer them to specialists and thus remain inexperienced in treating the disorder. As a result, many individuals, too, remain unaware of this disease in their families and thus do not consider mentioning its possibility to doctors or family members. Thus, intrafamilial disclosures by patients become critical. Patients may be shocked and upset at diagnosis, as they might possibly already have transmitted the mutation to offspring, which further impedes disclosure to family members. CONCLUSIONS These issues highlight how patients' interactions with doctors and others concerning genetics are critical, and need to be further explored and addressed. Several aspects of physician education and practice (e.g., regarding disclosures to at-risk family members) need to be improved.

Abstract
Genetic counseling has become the clinical bedrock of hereditary cancer management. Countless advances in molecular genetics contributing to the identification of cancer-causing germline mutations have increased its importance. We report a unique genetic counseling experience involving a family with hereditary chronic lymphocytic leukemia and the cancer-causing mutation in the death-associated protein kinase 1 gene (DAPK1). This hereditary disorder currently lacks any preventive or curative interventions for mutation carriers. This family has been under our investigation for a decade, during which time genealogy, cancer of all anatomic sites, medical and pathology records, and, whenever possible, slides and tissue blocks were reviewed. Family attendance at three group-oriented family information service sessions provided intensive education about this disease. Blood and skin fibroblasts were obtained for molecular genetic studies of DNA leading to the discovery of the DAPK1 mutation in the family. Their intellectual and emotional reaction to its presence or absence in them was assessed. This family serves as a model for genetic counseling in disorders for which lifesaving intervention is not yet possible.

Abstract
In this retrospective study, we examined changes in decision-making for and against the predictive genetic test for Huntington's disease including 478 persons at risk who had undergone genetic counselling in one centre in Germany between 1993 and 2004. At the outset of the counselling procedure the majority of subjects (71%) wanted to make use of the test, yet the actual demand of the predictive test result declined from 67 to 38% over the years. In addition, the time interval between counselling session and blood withdrawal was reduced, as determined by the counselees: in 2000-2004 the majority of persons at risk made the appointment for blood withdrawal after the shortest possible time span. Demographic factors of the cohort remained comparatively stable in the investigated time period. An association was evident between the ratio of test usage and the counselling person. These and other possible factors influencing the time flow of predictive DNA testing are discussed. Further studies are necessary to investigate whether changes of test demand rates are a general phenomenon.
