Evidence-Based Genetic Counseling for Psychiatric Disorders: A Road Map

Protocol for a new family history of addiction density score to aid in the treatment of alcohol and substance use disorders

Background

While molecular and non-molecular genetic testing are the gold standard for assessing a person's familial liability for substance use disorders, such testing is often inaccessible. Family history information collected at intake is an alternative, but tools to effectively utilize this information are excessively complex. The aims of the study are threefold: 1) Describe a protocol for the collection of family history in a thorough and straightforward manner. 2) Provide an algorithm to convert family history information to numerical scores. 3) Present the aggregated results from the pilot testing of the protocol.

Methods

All patients (N = 871) underwent a comprehensive assessment that included the family history protocol. Descriptive statistics, t-tests and Pearson Correlation were used to analyze the scores and determine key differences by demographic categories (sex/race/ethnicity/substance/age).

Results

The protocol asked patients four key questions about 1st and 2nd degree relatives while completing a family pedigree. Answers were transferred into an algorithm to output a score for each patient. This score took affectedness and relatedness of each family member into account. The average number of affected relatives was 5.24 (SD=3.17), and there were significant sex, race, and primary substance score differences.

Conclusions

This study provides the addiction field with a novel, freely available, and easily implementable family history protocol that has several potential clinical applications. While more research is needed, pilot results provide a valuable research tool, insight into a typical family history for those at an inpatient addiction treatment center, and steps toward closing the research-to-practice gap in this field.

Recent Advances in Schizophrenia Genomics and Emerging Clinical Implications

The conceptualization of schizophrenia has evolved from Emil Kraepelin's identification of "dementia praecox" as a distinct illness characterized by cognitive and functional deficits to the modern understanding of its complex nature. Recent research, including the "deficit syndrome," highlights enduring negative symptoms that correlate with poor functional outcomes. Genetic epidemiologic studies reveal a strong heritable basis (60%-80%) for schizophrenia, with its polygenic architecture overlapping with various mental health disorders. This complexity raises questions about targeted precision medicine. Recent advancements in biobanks and neurogenomics research are providing valuable insights that aim to improve patient outcomes through enhanced genomic understanding.

Genomics of Suicidal Behaviors: What Can We Learn from Polygenic Scores?

Substantial evidence supports the role of genetic factors in suicide behaviors (SBs). The most recent and powered genome-wide association studies identified significant loci for suicide, suicide attempts, and suicide ideation. Nonetheless, more research is needed to fully understand its impact. A novel approach considering the genetic complexity of SBs is polygenic scores that, in conjunction with individual and environmental factors, may have promising results to inform suicide risk stratification. Communicating this information to patients and the open population may have ethical implications that need to be considered to avoid iatrogenic effects.

The case for integrating genetic counselors into primary care: A paradigm shift for our profession

The integration of genetic counselors (GCs) into primary care represents an opportunity for a transformative shift in healthcare delivery, bridging the gap between the historical medical genetics delivery model and the increasing need for genetic services. This paradigm aligns the holistic ethos of primary care with the specialized expertise of genetic counseling and frontline access to preventive care, addressing critical barriers in genetic services. Current genetic service delivery models, concentrated in tertiary care settings, face limitations, including access disparities, fragmented care, and inefficiencies that disproportionately affect underserved populations. Embedding GCs within primary care leverages GCs' unique skills to enhance personalized healthcare delivery, improve risk assessment, and facilitate the implementation of precision medicine. GCs in primary care can streamline referrals, manage routine genetic concerns, and provide genetic continuity of care across the patient's lifespan. This integration ensures that genetic insights are contextualized within patients' day-to-day healthcare, fostering equitable and efficient access to genomic medicine. We explore the potential impact of primary care genetic counselors (PCGCs) on healthcare systems, emphasizing the alignment of their scope of practice with primary care principles such as accessibility, comprehensiveness, and continuity. By addressing evolving patient needs and collaborating with primary care teams, PCGCs can increase patient access, reduce system inefficiencies, alleviate pressures on specialty genetics services, and improve health equity. This paper advocates for a collaborative model where GCs are embedded within primary care, enabling proactive, prevention-focused interventions and enhancing patient outcomes. By integrating genetics into primary care settings, we reimagine genetic healthcare delivery to maximize the benefits of genomic medicine for all individuals. This paradigm shift underscores the urgency of addressing systemic barriers and advancing the role of GCs in healthcare to improve patient and clinician experiences, better population health, and achieve greater health equity.

Psychological and behavioural considerations for integrating polygenic risk scores for disease into clinical practice

A polygenic risk score (PRS) summarizes in one number an individual's estimated genetic association with a specific trait or disease based on the common DNA variants included in the score. Disease PRSs have the potential to positively affect population health by improving disease risk prediction, thereby also potentially improving disease prevention, early intervention and treatment. However, given the potential psychological, behavioural and other harms, there are also concerns about integrating PRSs into clinical tools and healthcare systems. Here we assess five arguments against implementing PRSs for physical disease in clinical practice that revolve around psychological and behavioural considerations. For each argument, we consider a counterargument, the evidence and underlying theory, any gaps in the evidence base and possible future directions and research priorities. We conclude that, although there may be other barriers to implementation, there is currently little evidence of psychological or behavioural harms from integrating PRSs into practice.

Genetic counselling for psychiatric conditions: exploring current perceptions of family physicians and psychiatrists in Portugal

Genetic counselling emerged as a specialized healthcare discipline in the 1960s, and since then, various sub-specialties have developed globally, namely and more recently, psychiatric genetic counselling. This study provides a pioneering exploration of family physicians and psychiatrists' perceptions regarding genetic counselling provision and its potentialities in the context of psychiatric illnesses in Portugal. A qualitative methodology with semi-structured interviews was used. Among the participants, five were family physicians, and six were psychiatrists. Thematic analysis revealed three themes: (1) the role of genetics in healthcare, (2) barriers to psychiatric genetic counselling implementation, and (3) perceived benefits associated with its implementation. Results show that while the importance of genetics in psychiatric disorders is acknowledged, there is low literacy about genetic counselling practice from the professional groups interviewed. Also, the availability and mainstreaming of genetic testing seem to influence how genetic counselling is perceived and utilized. There is a perceived need for training and guidelines that foster the dissemination of genetics into healthcare, specifically mental healthcare. A holistic and patient-centred approach is considered essential in managing psychiatric disorders and, by extension, in psychiatric genetic counselling, as it addresses both medical and psychosocial factors. Although psychiatrists and family physicians are keen to integrate psychiatric genetic counselling into their patients' care, it seems that certain fundamental challenges still persist in genetic healthcare provision. Future research should contribute for a more comprehensive evaluation of the readiness for psychiatric genetic counselling implementation in the country.

Psychological state at the time of psychiatric genetic counseling impacts patient empowerment: A pre-post analysis

Psychiatric genetic counseling (GC) has been associated with patient-reported increases in empowerment (perceived control, emotional regulation, and hope). We sought to evaluate the extent to which patients' psychological state at the time of GC is related to changes in empowerment. Participants with a history of major depressive disorder and/or bipolar disorder that had been refractory to treatment underwent psychiatric GC remotely from 2022 to 2023. GC was performed by four genetic counselors and included discussion of perceived causes of illness, multifactorial inheritance, and protective factors. Empowerment, depression, and anxiety were measured immediately prior to GC via online survey by the GCOS-16, PHQ-9, and GAD-7, respectively. Empowerment was re-assessed 2 weeks later. In total, 66/161 (41.0%) invited individuals completed both the baseline and follow-up surveys. Participants completing both surveys were 54.6% female, 84.8% white, and ranged in age from 22 to 78 years (mean = 54.8 years). Overall, a significant change in mean empowerment was not observed (p = 0.38); however, there were moderating effects by baseline psychological state. A multiple linear regression model incorporating PHQ-9, GAD-7 and baseline GCOS-16 score predicted change in empowerment with a large effect (F = 5.49, R2 = 0.21, p < 0.01). A higher score on the PHQ-9 was associated with decreases in empowerment from pre to post GC. Higher scores on the GAD-7 and lower baseline GCOS-16 scores were associated with increases in empowerment. Further, two-way ANOVA was conducted to assess change in empowerment between subgroups based on the level of anxiety and depression. Those with low depression and high anxiety reported significant increases in empowerment (F = 6.64, p = 0.01). These findings suggest that psychiatric GC may be especially helpful to individuals experiencing anxiety and low baseline empowerment. Alternative approaches may be needed to best meet the needs of those experiencing significant depression.

Unresolved ethical issues of genetic counseling and testing in clinical psychiatry

OBJECTIVE

This position article discusses current major ethical and social issues related to genetic counseling and testing in clinical psychiatry (PsyGCT).

METHODS

To address these complex issues in the context of clinical psychiatry relevant to PsyGCT, the interdisciplinary and pan-European expert Network EnGagE (Enhancing Psychiatric Genetic Counseling, Testing, and Training in Europe; CA17130) was established in 2018. We conducted an interdisciplinary, international workshop at which we identified gaps across European healthcare services and research in PsyGCT; the workshop output was summarized and systematized for this position article.

RESULTS

Four main unresolved ethical topics were identified as most relevant for the implementation of PsyGCT: (1) the problematic dualism between somatic and psychiatric disorders, (2) the impact of genetic testing on stigma, (3) fulfilling professional responsibilities, and (4) ethical issues in public health services. We provide basic recommendations to inform psychiatrists and other healthcare professionals involved in the clinical implementation of PsyGCT and conclude by pointing to avenues of future ethics research in PsyGCT.

CONCLUSION

This article draws attention to a set of unresolved ethical issues relevant for mental health professionals, professionals within clinical genetics, patients and their family members, and society as a whole and stresses the need for more interdisciplinary exchange to define standards in psychiatric counseling as well as in public communication. The use of PsyGCT may, in the future, expand and include genetic testing for additional psychiatric diagnoses. We advocate the development of pan-European ethical standards addressing the four identified areas of ethical-practical relevance in PsyGCT.

Psychiatric Genetics in Clinical Practice: Essential Knowledge for Mental Health Professionals

OBJECTIVE

The authors provide recommendations on incorporating recent advances in psychiatric genetics into clinical practice for mental health clinicians.

METHOD

The International Society for Psychiatric Genetics Education Committee met monthly to come to a consensus on priority topics in psychiatric genetics. Topics were then assigned to small teams of subspecialty experts to summarize the current knowledge base and create an illustrative clinical case. Topics included, familial aggregation, common and rare genetic variants, epigenetics, gene-environment interactions, pharmacogenomics, genetic counseling, and ethical and social implications. Each section was reviewed and revised by all committee members and then finalized by the Committee Chair.

RESULTS

Key findings highlight the importance of understanding the genetic architecture of psychiatric disorders, the potential applications of genetic information in risk assessment, diagnosis, treatment selection, and patient education, as well as the ethical and social considerations surrounding the use of genetic data. The committee emphasizes the need for a nuanced approach that integrates genetic factors with environmental and experiential factors in a holistic model of care.

CONCLUSION

As psychiatric genetics continues to evolve rapidly, mental health clinicians must stay informed about the latest findings and their clinical implications. Ongoing education, collaboration with genetics professionals, and effective communication strategies are crucial to harness the power of genetics while avoiding potential pitfalls such as genetic determinism and stigma. The committee recommends a balanced perspective that recognizes the complex interplay of genetic and non-genetic factors in shaping mental health outcomes.

The importance of genetic counselling for turner syndrome transition

The healthcare transition (HCT) is the process of planning, monitoring, and adjusting the clinical management from children's care to adult specialists. Although this practice is common for all children, it is especially crucial (and challenging) for those with chronic disorders and genetic conditions that also involve mental health issues, requiring a multidisciplinary approach. In this review, we aim to assess the current status of transition for girls and young women with Turner syndrome (TS) as a model as it is one of the most common sexual chromosomal aneuploidies. We first describe the syndrome highlighting some of the challenges regarding behavioural, neurodevelopmental, and mental health characteristics that must be addressed for a successful HCT. Finally, we emphasize the importance of genetic counselling within multidisciplinary groups for the successful implementation of HCT, especially for girls and women with TS, to facilitate their adaptation and adhesion to the transition process.

Application of Genetic Testing for Anorexia Nervosa: An Ethical Analysis

OBJECTIVE

Anorexia Nervosa (AN) is a severe, debilitating disorder with a high mortality rate. Research indicates that genetics plays a significant role in AN manifestation and persistence. Genetic testing has the potential to transform how AN is treated, however, in clinical practice, care must be taken to consider the ethical complexities involved. Our objective was to perform an ethical analysis of genetic testing in AN.

METHODS

We applied the principlist approach, taking into consideration the stakeholders involved and the core ethical principles of autonomy, beneficence, non-maleficence, and justice to (1) evaluate the possible ethical implications of the use of genetic testing in the treatment of patients with AN, and (2) assess whether such testing is justified and if so, under what conditions.

RESULTS

Potential benefits of genetic testing identified include reduction of misdiagnosis and identification of treatable concurrent genetic conditions. The identified potential risks of genetic testing for possible AN-associated risk variants outside of a research setting, especially without more effective treatment options, include a false sense of reassurance for those testing negative and a reduced emphasis on the importance of behavioral-based therapies that may be of benefit.

DISCUSSION

Genetic testing for complex disorders, including AN, has tremendous potential, but is still primarily research-based. Currently, for those presenting with atypical AN, and severe and enduring AN who, by definition, have not benefited from traditional treatment, genetic testing to rule out or identify other genetic conditions could be of benefit.

Advancing Mental Health Research Through Strategic Integration of Transdiagnostic Dimensions and Genomics

Genome-wide studies are yielding a growing catalog of common and rare variants that confer risk for psychopathology. However, despite representing unprecedented progress, emerging data also indicate that the full promise of psychiatric genetics-including understanding pathophysiology and improving personalized care-will not be fully realized by targeting traditional dichotomous diagnostic categories. The current article provides reflections on themes that emerged from a 2021 National Institute of Mental Health-sponsored conference convened to address strategies for the evolving field of psychiatric genetics. As anticipated by the National Institute of Mental Health's Research Domain Criteria framework, multilevel investigations of dimensional and transdiagnostic phenotypes, particularly when integrated with biobanks and big data, will be critical to advancing knowledge. The path forward will also require more diverse representation in source studies. Additionally, progress will be catalyzed by a range of converging approaches, including capitalizing on computational methods, pursuing biological insights, working within a developmental framework, and engaging health care systems and patient communities.

No prediction without prevention: A global qualitative study of attitudes toward using a prediction tool for risk of developing depression during adolescence

Given the rate of advancement in predictive psychiatry, there is a threat that it outpaces public and professional willingness for use in clinical care and public health. Prediction tools in psychiatry estimate the risk of future development of mental health conditions. Prediction tools used with young populations have the potential to reduce the worldwide burden of depression. However, little is known globally about adolescents' and other stakeholders' attitudes toward use of depression prediction tools. To address this, key informant interviews and focus group discussions were conducted in Brazil, Nepal, Nigeria and the United Kingdom with 23 adolescents, 45 parents, 47 teachers, 48 health-care practitioners and 78 other stakeholders (total sample = 241) to assess attitudes toward using a depression prediction risk calculator based on the Identifying Depression Early in Adolescence Risk Score. Three attributes were identified for an acceptable depression prediction tool: it should be understandable, confidential and actionable. Understandability includes depression literacy and differentiating between having a condition versus risk of a condition. Confidentiality concerns are disclosing risk and impeding educational and occupational opportunities. Prediction results must also be actionable through prevention services for high-risk adolescents. Six recommendations are provided to guide research on attitudes and preparedness for implementing prediction tools.

Building Confidence in Discussing Genetics With Patients With Eating Disorders and Their Families

Many individuals with eating disorders and their family members are well-informed about advances in science that could affect the treatment and outcome of these illnesses. They appropriately apply this knowledge to evaluate available treatments and advocate for the best possible evidence-based care. They ask hard questions that many clinicians are often ill-prepared to answer. Genetics has advanced our understanding of eating disorders and provides a novel lens through which to understand these pernicious illnesses. Clinicians can now update their understanding of the etiology of eating disorders and abandon outdated etiological theories, some of which have done harm to patients and their families. Without becoming expert in psychiatric genetics, psychiatrists and other mental health care professionals can develop a general overview of the science, understand what it can and cannot offer, incorporate genetic factors into their case conceptualizations, and boost their confidence in discussing these topics with patients and families.

Assessing the impact of psychiatric genetic counseling on psychiatric hospitalizations

Psychiatric genetic counseling (pGC) can improve patient empowerment and self-efficacy. We explored the relationship between pGC and psychiatric hospitalizations, for which no prior data exist. Using Population Data BC (a provincial dataset), we tested two hypotheses: (1) among patients (>18 years) with psychiatric conditions who received pGC between May 2010 and Dec 2016 (N = 387), compared with the year pre-pGC, in the year post-pGC there would be fewer (a) individuals hospitalized and (b) total hospital admissions; and (2) using a matched cohort design, compared with controls (N = 363, matched 1:4 for sex, diagnosis, time since diagnosis, region, and age, and assigned a pseudo pGC index date), the pGC cohort (N = 91) would have (a) more individuals whose number of hospitalizations decreased and (b) fewer hospitalizations post-pGC/pseudo-index. We also explored total days in hospital. Within the pGC cohort, there were fewer hospitalizations post-pGC than pre- pGC (p = 0.011, OR = 1.69), and total days in hospital decreased (1085 to 669). However, when compared to matched controls, the post-pGC/pseudo index change in hospitalizations among pGC cases was not statistically significant, even after controlling for the higher number of hospitalizations prior. pGC may lead to fewer psychiatric hospitalizations and cost savings; further studies exploring this are warranted.

Consumer attitudes and preferences toward psychiatric genetic counselling and educational resources: A scoping review

INTRODUCTION

The etiology of psychiatric disorders is multifactorial including genomic and environmental risk factors. Psychiatric genetic counseling is an emerging field that may promote processes of adaptation to, and the management of, psychiatric disorders. Many countries lack dedicated services leading to a gap in care. This scoping review will inform the development of psychiatric genetics-based educational resources.

OBJECTIVES

To explore individuals with a psychiatric disorder and their relatives' attitudes and beliefs toward psychiatric genetics, genetic counseling, and genetics-based education. To evaluate how best to convey education to consumers.

METHOD

Database literature searches occurred on May 2nd, 2023, using PubMed, Medline, and PsycINFO. Reviews, letters to the editor, case reports, and publications before 2003 were excluded.

RESULTS

Twenty-four papers met the inclusion criteria. Results suggest individuals with a psychiatric disorder and their relatives tended to overestimate risk, and express concern about reproductive decision- making. Genetic counseling and educational resources were perceived to be useful and empowering.

CONCLUSION

Affected individuals and relatives are interested in gaining greater insight into their own and/or their relative's psychiatric disorder, management strategies, and understanding familial risks.

PRACTICE IMPLICATIONS

The evidence from this review may inform the development of genetics-based educational resources or guide future research.

Assessment of Brief Online Approaches for Teaching Neuroscience in Psychiatry

OBJECTIVE

The goal of this study was to assess an online collection of brief educational resources (videos, case studies, articles) for teaching a broad range of concepts relating to neuroscience in psychiatry.

METHODS

A national sample of 52 psychiatrists enrolled in the study. Forty (77%) completed an assessment before and after having access to the educational resources for 4 weeks. Pre- and post-assessments were compared using paired t-tests. Fifteen participants were randomly selected to participate in a semi-structured interview.

RESULTS

The mean knowledge score increased on a multiple-choice quiz from 46.9 to 86.4% (p < .01). Based on a 5-point Likert rating, participants reported significant gains in self-confidence in their ability to integrate a neuroscience perspective into their clinical work (p = .03) and to discuss neuroscience with their patients (p = .008). Participants rated the extent that they applied neuroscience concepts (such as neurotransmitters, genetics, epigenetics, synaptic plasticity, and neural circuitry) to their overall case formulation and treatment plan over the past typical work week and how often they discussed these elements with patients. Significant gains were noted across all elements (p ≤ .001). Overall satisfaction with the resources were high: participants agreed that the content was useful and relevant (100%) and the teaching resources were engaging (95%). On semi-structured interviews, participants appreciated the mixed teaching approaches and the brief format. Many commented on how the resources impacted their clinical practice.

CONCLUSIONS

Brief online teaching resources may be an effective approach for enhancing neuroscience education among psychiatrists and may help facilitate the integration of neuroscience into clinical practice.

A genetics-guided approach to the clinical management of schizophrenia

Schizophrenia is a highly heritable, severe mental illness characterized by hallucinations, delusions, social withdrawal, and cognitive dysfunction present in ∼1% of populations across cultures. There have been recent major advancements in our understanding of the genetic architecture of schizophrenia. Both rare, highly penetrant genetic variants as well as common, low-penetrant genetic variants can predispose individuals to schizophrenia and can impact the way people metabolize psychoactive medications used to treat schizophrenia. However, the impact of these findings on the clinical management of schizophrenia remains limited. This review highlights the few places where genetics currently informs schizophrenia management strategies, discusses major limitations, and reviews promising areas of genetics research that are most likely to impact future schizophrenia care. Specifically, I focuss on psychiatric genetic counseling, genetic testing strategies, pharmacogenetics, polygenic risk, and genetics-guided treatment. Lastly, I emphasize important ethical considerations in the clinical use of genetics for schizophrenia management, including the exacerbation of healthcare inequalities and unintended consequences of new genetic technologies.

The translation of psychiatric genetic findings to the clinic

Mental health and neurodevelopmental disorders are highly heritable and can affect morbidity and mortality. A large, growing body of evidence has implicated both common and rare variation in the risk of these disorders. Testing for rare variants, such as copy number variants, has been available in clinical practice for some time in the context of developmental disorders. However, until recently, individuals with mental health and neurodevelopmental disorders in the UK have not tended to access genetic counselling and testing. Here, we describe the development of the All Wales Psychiatric Genomics Service, a collaborative effort between psychiatric and clinical genetics services and the first of its kind in the UK. We provide an overview of the structure and function of the service, our referral criteria, a summary of the 40 referrals we have received to date and our future plans.

The effectiveness of psychiatric genetic counseling training: An analysis of 13 international workshops

Studies have consistently shown that psychiatric genetic counseling (pGC) helps people with psychiatric conditions by increasing empowerment and self-efficacy, and addressing emotions like guilt. Yet, it is not routinely provided. Genetic counselors and trainees express low confidence in their ability to provide meaningful pGC, especially in the absence of adequate training. Therefore, to address this gap a "Psychiatric Genetic Counseling for Genetic Counselors" (PG4GC) workshop was developed and delivered to 13 groups of participants (primarily qualified genetic counselors and trainees) between 2015 and 2023 (10 workshops were delivered in-person, and three virtually). Participants completed quantitative questionnaires both before and after completing the workshop to assess their comfort, knowledge, behavior, and feeling of being equipped to provide pGC. In total, 232 individuals completed the pre-workshop questionnaire and 154 completed the post-workshop questionnaire. Participants felt more comfortable, knowledgeable, and equipped to provide pGC, and reported being more likely to address psychiatric concerns after the workshop, regardless of whether they were trainees or practicing professionals and whether they completed the workshop in-person or virtually. This study suggests that the PG4GC workshop is an effective educational tool in pGC training that may aid in broader implementation of the service.

Psychiatrists' perceptions of and reactions to a simulated psychiatric genetic counseling session

Psychiatric genetic counseling (pGC) has been demonstrated to have meaningful positive outcomes for people with psychiatric conditions and their families. However, it is not widely accessed, and clinical genetics services tend to receive few referrals for these indications. Little research has evaluated psychiatrists' perceptions of and experience with interfacing with pGC. Therefore, we invited Ontario-based psychiatrists to participate in a study in which they first watched a simulated pGC session (representative of typical practice: the patient had depression with no exceptionally dense family history of psychiatric conditions, no genetic testing is provided, and no family-based risk assessment is performed), then completed zoom-based qualitative semi-structured interviews. Interviews were recorded, transcribed verbatim and checked for accuracy. Using interpretive description to analyze interviews with 12 psychiatrists (data collection was stopped at this point, as theoretical sufficiency was achieved), we generated two theoretical models: the first described the decision-making pathway psychiatrists currently follow when determining whether and how to address genetics with a patient; the second described psychiatrists' ideas for integrating pGC into care models for the future. Our data shed light on how to facilitate the delivery of pGC for people with psychiatric conditions and their families.

Beyond multiple choice: Clinical simulation as a rigorous and inclusive method for assessing genetic counseling competencies

Educational use of clinical simulation is a way for students to immerse themselves within a realistic yet safe and structured environment as they practice clinical skills. It is widely used in healthcare training and evaluation, and there are best practices for design, implementation, debriefing, and assessment. An increasing number of genetic counseling graduate programs use simulation in various ways, ranging from role-plays to working with professional simulated/standardized patient (SP) actors. At this time, there is very little consistency across programs, research on the approaches, and standards by which simulation is incorporated into training. Simulation is an understudied but promising approach for genetic counselor (GC) education and assessment. After graduation, GCs demonstrate their competence as entry-level providers through American Board of Genetic Counseling (ABGC) multiple-choice examination (MCE), along with their participatory clinical encounters from graduate training. Data from genetic counseling and other professions highlight the limitations and biases of MCEs, suggesting they not only fail to accurately capture competency, but also that they disadvantage underrepresented individuals from entering the field. In addition, MCEs are limited as a tool for assessing nuanced counseling and communication skills, as compared to more quantitative scientific knowledge. We propose that innovative, evidence-based approaches such as simulation have the potential to not only enhance learning, but also to allow GCs to better demonstrate competency during training and in relation to the board examination. Collaborative approaches, research, and funding are needed to further explore the viability of routinely incorporating simulation into GC training and assessment.

Global trends and themes in genetic counseling research

This article seeks to highlight the most recent trends and themes in genetic counseling that are of broad interest. A total of 3505 documents were published between 1952 and 2021, with a trend toward increase in paper/year. The most common documents are original articles (2515, 71.8%), followed by review articles (341, 9.7%). Journal of Genetic Counseling publishes the highest number of genetic counseling articles (587, 16.7%), followed by Clinical Genetics (103, 2.9%) and the South American Journal of Medical Genetics (95, 2.7%). Co-occurrence analysis revealed five research themes: genetic testing, cancer, genetic counselor, prenatal diagnosis, and psychiatry. The genetic counselor theme contained most of the recent keywords, including "covid-19," "underrepresented population," "service delivery models," "workforce," "disparities," "service delivery," "professional development," "cultural competence," "access," "diversity," "telemedicine," and "health literacy." Genetic counseling researchers may use these keywords to find topics pertinent to their future research and practice.

Spanish mental health residents' perspectives about residency education on the genetics of psychiatric disorders: A cross-sectional survey

Despite compelling evidence that some patients with a psychiatric diagnosis could benefit from genetic assessment, genetic testing for psychiatric patients is underutilized. Few studies have reported psychiatric genetics training for mental health specialists, and such research is especially lacking in Spain. We aimed to gather the opinions of Spanish mental health residents, including resident intern nurses (RINs), doctors (RIDs) and psychologists (RIPs). A short survey was prepared by an expert team and distributed to all mental health residency centers in Spain during the first semester of 2021. Of the 2028 residents, 18% responded. Participants were mainly females (71%), in their first year of residency (37%) and within the 27-31-year age range. While participants received little theoretical (13.4%) and practical (4.6%) training on average, RIDs had the most affirmative responses. Notably, RINs and RIDs were interested in genetics during residency (>40%) and strongly believed (85.0%) that genetics training using both theoretical and practical methodologies should be incorporated into residency training. However, RIPs were less interested (20%), and only 60% believed that genetics training should be incorporated. Spanish mental health residents, although interested in genetics in psychiatry, receive little training on this topic. They strongly believe that genetics training using theoretical and practical methodologies should be incorporated.

How do experts in psychiatric genetics view the clinical utility of polygenic risk scores for schizophrenia?

Polygenic risk scores (PRS) are promising for identifying common variant-related inheritance for psychiatric conditions but their integration into clinical practice depends on their clinical utility and psychiatrists' understanding of PRS. Our online survey explored these issues with 276 professionals working in psychiatric genetics (RR: 19%). Overall, participants demonstrated knowledge of how to interpret PRS results. Their performance on knowledge-based questions was positively correlated with participants' self-reported familiarity with PRS (r = 0.21, p = 0.0006) although differences were not statistically significant (Wald Chi-square = 3.29, df = 1, p = 0.07). However, only 48.9% of all participants answered all knowledge questions correctly. Many participants (56.5%), especially researchers (42%), indicated having at least occasional conversations about the role of genetics in psychiatric conditions with patients and/or family members. Most participants (62.7%) indicated that PRS are not yet sufficiently robust for assessment of susceptibility to schizophrenia; most significant obstacles were low predictive power and lack of population diversity in available PRS (selected, respectively, by 53.6% and 29.3% of participants). Nevertheless, 89.8% of participants were optimistic about the use of PRS in the next 10 years, suggesting a belief that current shortcomings could be addressed. Our findings inform about the perceptions of psychiatric professionals regarding PRS and the application of PRS in psychiatry.

Transdiagnostic risk of mental disorders in offspring of affected parents: a meta-analysis of family high-risk and registry studies

The offspring of parents with mental disorders are at increased risk for developing mental disorders themselves. The risk to offspring may extend transdiagnostically to disorders other than those present in the parents. The literature on this topic is vast but mixed. To inform targeted prevention and genetic counseling, we performed a comprehensive, PRISMA 2020-compliant meta-analysis. We systematically searched the literature published up to September 2022 to retrieve original family high-risk and registry studies reporting on the risk of mental disorders in offspring of parents with any type of mental disorder. We performed random-effects meta-analyses of the relative risk (risk ratio, RR) and absolute risk (lifetime, up to the age at assessment) of mental disorders, defined according to the ICD or DSM. Cumulative incidence by offspring age was determined using meta-analytic Kaplan-Meier curves. We measured heterogeneity with the I2 statistic, and risk of bias with the Quality In Prognosis Studies (QUIPS) tool. Sensitivity analyses addressed the impact of study design (family high-risk vs. registry) and specific vs. transdiagnostic risks. Transdiagnosticity was appraised with the TRANSD criteria. We identified 211 independent studies that reported data on 3,172,115 offspring of parents with psychotic, bipolar, depressive, disruptive, attention-deficit/hyperactivity, anxiety, substance use, eating, obsessive-compulsive, and borderline personality disorders, and 20,428,575 control offspring. The RR and lifetime risk of developing any mental disorder were 3.0 and 55% in offspring of parents with anxiety disorders; 2.6 and 17% in offspring of those with psychosis; 2.1 and 55% in offspring of those with bipolar disorder; 1.9 and 51% in offspring of those with depressive disorders; and 1.5 and 38% in offspring of those with substance use disorders. The offspring's RR and lifetime risk of developing the same mental disorder diagnosed in their parent were 8.4 and 32% for attention-deficit/hyperactivity disorder; 5.8 and 8% for psychosis; 5.1 and 5% for bipolar disorder; 2.8 and 9% for substance use disorders; 2.3 and 14% for depressive disorders; 2.3 and 1% for eating disorders; and 2.2 and 31% for anxiety disorders. There were 37 significant transdiagnostic associations between parental mental disorders and the RR of developing a different mental disorder in the offspring. In offspring of parents with psychosis, bipolar and depressive disorder, the risk of the same disorder onset emerged at 16, 5 and 6 years, and cumulated to 3%, 19% and 24% by age 18; and to 8%, 36% and 46% by age 28. Heterogeneity ranged from 0 to 0.98, and 96% of studies were at high risk of bias. Sensitivity analyses restricted to prospective family high-risk studies confirmed the pattern of findings with similar RR, but with greater absolute risks compared to analyses of all study types. This study demonstrates at a global, meta-analytic level that offspring of affected parents have strongly elevated RR and lifetime risk of developing any mental disorder as well as the same mental disorder diagnosed in the parent. The transdiagnostic risks suggest that offspring of parents with a range of mental disorders should be considered as candidates for targeted primary prevention.

Knowledge, Attitude, and Practice About the Process of Genetic Counselling Among Clinicians

Introduction Clinicians agree with the fact that the impact of genetics in the field of medicine is humongous. They have to cope with the rapid advances in the field of clinical genetics and offer the best treatment to the patients at the right time. Disease with an underlying genetic cause not only involves the patient but also the family and the community. In the process of genetic counseling, the patient and the family are educated about the genetic basis of the disorder. This helps the patient and the family to make a well-informed decision. It also helps to reduce the genetic burden of the disease in the community over a period of time. In this regard, knowledge, attitude, and practice about the process of genetic counseling among clinicians is imperative. Methods A structured pre-validated questionnaire was distributed amongst 60 clinicians from different departments. Their responses were assessed based on the Likert scale. The data obtained were analyzed using descriptive statistics and expressed in percentages.  Results In the present study, nearly 90% of the clinicians felt that it was important to gather a multi-generational family history of the patient and advise them about inheritance patterns, recurrence risk, and genetic tests for a disorder with an underlying genetic cause. The need to educate the family members regarding the importance of genetic tests and referral to appropriate support groups if they test positive for a genetic disorder receive a positive response. Mostly the participants agreed that parents of children and couples at risk of having a child affected by a genetic disease should undergo genetic counseling. Conclusion Clinicians may not always be aware of the underlying genetic cause and genetic tests available or may face a paucity of time to counsel the patient and the family. Genetic counseling needs to be done at length in multiple sessions, and it is essential to reduce the burden of genetic disorders in society.

Lack of guidelines and translational knowledge is hindering the implementation of psychiatric genetic counseling and testing within Europe - A multi-professional survey study

Genetic research has identified a large number of genetic variants, both rare and common, underlying neurodevelopmental disorders (NDD) and major psychiatric disorders. Currently, these findings are being translated into clinical practice. However, there is a lack of knowledge and guidelines for psychiatric genetic testing (PsychGT) and genetic counseling (PsychGC). The European Union-funded COST action EnGagE (CA17130) network was started to investigate the current implementation status of PsychGT and PsychGC across 35 participating European countries. Here, we present the results of a pan-European online survey in which we gathered the opinions, knowledge, and practices of a self-selected sample of professionals involved/interested in the field. We received answers from 181 respondents. The three main occupational categories were genetic counselor (21.0%), clinical geneticist (24.9%), and researcher (25.4%). Of all 181 respondents, 106 provide GC for any psychiatric disorder or NDD, corresponding to 58.6% of the whole group ranging from 43.2% in Central Eastern Europe to 66.1% in Western Europe. Overall, 65.2% of the respondents reported that genetic testing is offered to individuals with NDD, and 26.5% indicated the same for individuals with major psychiatric disorders. Only 22.1% of the respondents indicated that they have guidelines for PsychGT. Pharmacogenetic testing actionable for psychiatric disorders was offered by 15%. Interestingly, when genetic tests are fully covered by national health insurance, more genetic testing is provided for individuals with NDD but not those with major psychiatric disorders. Our qualitative analyses of responses highlight the lack of guidelines and knowledge on utilizing and using genetic tests and education and training as the major obstacles to implementation. Indeed, the existence of psychiatric genetic training courses was confirmed by only 11.6% of respondents. The question on the relevance of up-to-date education and training in psychiatric genetics on everyday related practice was highly relevant. We provide evidence that PsychGC and PsychGT are already in use across European countries, but there is a lack of guidelines and education. Harmonization of practice and development of guidelines for genetic counseling, testing, and training professionals would improve equality and access to quality care for individuals with psychiatric disorders within Europe.

Ethical principles, challenges and opportunities when conducting genetic counselling for schizophrenia

Ethical challenges of genetic counselling for schizophrenia include effective communication of critical scientific information in an easily understood manner by patients and relatives, and the ability to ensure communication is unencumbered by medical jargon. Levels of literacy in the target population may limit this process, making it difficult for patients to attain the desired levels of informed consent to make crucial decisions during genetic counselling. Multilingualism in target communities may further complicate such communication. This paper outlines the ethical principles, challenges and opportunities facing clinicians when conducting genetic counselling for schizophrenia and how these might be met, drawing on lessons from South African studies. The paper draws on reflections of clinician and researcher experiences gained from clinical practice or research on the genetics of schizophrenia and psychotic disorders in South Africa. The context of genetic studies in schizophrenia is used to illustrate the ethical challenges in genetic counselling for schizophrenia, both in clinical and research settings. Attention is also drawn to multicultural and multilingual populations, particularly where the preferred language lacks a well-developed scientific language of communication for some of the genetic concepts that have to be presented during the genetic counselling process. The authors describe the ethical challenges and how to address these to empower patients and relatives to make well-informed decisions despite these obstacles. Principles applied by clinicians and researchers during the genetic counselling are described. Potential solutions, including the establishment of community advisory boards to address potential ethical challenges inherent to the genetic counselling process, are also shared. Genetic counselling for schizophrenia still faces ethical challenges which require a balance of principles of beneficence, autonomy, informed consent, confidentiality and distributive justice, while striving to present accuracy in the science that guides the process. Evolution in language and cultural competency therefore needs to occur alongside scientific advances in genetic research. Key stakeholders need to partner and build capacity and expertise in genetic counselling through the provision of funding and resources. The goal of partnerships is to empower patients, relatives, clinicians and researchers to share scientific information in a manner guided by empathy while retaining scientific accuracy.

The interplay of family history of depression and early trauma: associations with lifetime and current depression in the German national cohort (NAKO)

Introduction

Family history of depression and childhood maltreatment are established risk factors for depression. However, how these factors are interrelated and jointly influence depression risk is not well understood. The present study investigated (i) if childhood maltreatment is associated with a family history of depression (ii) if family history and childhood maltreatment are associated with increased lifetime and current depression, and whether both factors interact beyond their main effects, and (iii) if family history affects lifetime and current depression via childhood maltreatment.

Methods

Analyses were based on a subgroup of the first 100,000 participants of the German National Cohort (NAKO), with complete information (58,703 participants, mean age = 51.2 years, 53% female). Parental family history of depression was assessed via self-report, childhood maltreatment with the Childhood Trauma Screener (CTS), lifetime depression with self-reported physician's diagnosis and the Mini-International Neuropsychiatric Interview (MINI), and current depressive symptoms with the depression scale of the Patient Health Questionnaire (PHQ-9). Generalized linear models were used to test main and interaction effects. Mediation was tested using causal mediation analyses.

Results

Higher frequencies of the childhood maltreatment measures were found in subjects reporting a positive family history of depression. Family history and childhood maltreatment were independently associated with increased depression. No statistical interactions of family history and childhood maltreatment were found for the lifetime depression measures. For current depressive symptoms (PHQ-9 sum score), an interaction was found, with stronger associations of childhood maltreatment and depression in subjects with a positive family history. Childhood maltreatment was estimated to mediate 7%-12% of the effect of family history on depression, with higher mediated proportions in subjects whose parents had a depression onset below 40 years. Abuse showed stronger associations with family history and depression, and higher mediated proportions of family history effects on depression than neglect.

Discussion

The present study confirms the association of childhood maltreatment and family history with depression in a large population-based cohort. While analyses provide little evidence for the joint effects of both risk factors on depression beyond their individual effects, results are consistent with family history affecting depression via childhood maltreatment to a small extent.

Support to caregivers who have received genetic information about neurodevelopmental and psychiatric vulnerability in their young children: A narrative review

Diagnosis of pathogenic genetic variants associated with neurodevelopmental and psychiatric disorders (NPDs) is increasingly made early in life. This narrative review focuses on the need for, and provision of, psychological supports following genetic diagnosis. We conducted a literature search of publications on how caregivers are informed about the NPD vulnerability associated with genetic variants, challenges and unmet needs when receiving this information, and whether psychological supports are provided. Given its early recognition, the 22q11.2 deletion has been studied thoroughly for two decades, providing generalizable insights. This literature indicates the complex caregivers' needs related to learning about potential NPD vulnerabilities associated with a genetic variant, include how to communicate the diagnosis, how to identify early signs of NPDs, how to deal with stigma and a lack of medical expertise outside of specialized genetics clinics. With one exception, no publications describe psychotherapeutic support provided to parents. In the absence of support, caregivers struggle with several unmet needs regarding potential longer-term NPD implications of a genetic diagnosis. The field needs to go beyond explaining genetic diagnoses and associated vulnerabilities, and develop approaches to support caregivers with communicating and managing NPD implications across the child's lifespan.

Something old, something new - can adding genomic data to family studies advance our understanding of the impact of nature and nurture on mental health? Commentary on McAdams et al. (2023)

In their annual research review, McAdams, Cheesman, and Ahmadzadeh (2023) provide a thorough overview of how the use of novel genetically informative approaches can increase our knowledge about the intergenerational transmission of psychopathology. Many JCPP readers will already be familiar with genetically sensitive family-based designs, such as twin and adoption studies, as well as with newer molecular-genetic approaches, such as polygenic-score studies. McAdams et al.'s (2023) review discusses the innovative combination of family-based and molecular-genetic methods, and what this combination can reveal about developmental psychopathology.

The impact of receiving polygenic risk scores for alcohol use disorder on psychological distress, risk perception, and intentions to reduce drinking

For the return of polygenic risk scores to become an acceptable clinical practice in psychiatry, receipt of polygenic risk scores must be associated with minimal harm and changes in behavior that decrease one's risk for developing a psychiatric outcome. Data from a randomized controlled trial was used to assess the impact of different levels of hypothetical polygenic risk scores for alcohol use disorder on psychological distress, risk perception, and intentions to change drinking behaviors. The analytic sample consisted of 325 participants recruited from an urban, public university. Results demonstrated that there were significant increases in psychological distress as the level of genetic risk for alcohol use disorder increased. In addition, the perceived chance of developing alcohol use disorder significantly increased as the level of genetic risk increased. Promisingly, a greater proportion of participants indicated that they would intend to engage in follow-up behaviors, such as seeking additional information, talking to a healthcare provider about risk, and reducing drinking behaviors, as the level of genetic risk increased. Returning polygenic risk scores for alcohol use disorder in a clinical setting has the potential to promote risk-reducing behavior change, especially with increasing levels of genetic risk. The study was registered on ClinicalTrials.gov (Identifier: NCT05143073).

Examining the effect of patient personality types and coping styles on outcomes of genetic counseling

Both empirical data and genetic counselors' clinical experience suggest that patients differ in the extent to which they benefit from genetic counseling (GC). Understanding the origins of these differences could help adapt services to ensure that all patients benefit fully, and potentially inform triage. Although patient personality dimensions and coping styles have been shown to influence outcomes of other psychological interventions, they have remained largely unexplored in relation to GC outcomes. We conducted an exploratory, descriptive study to assess relationships between patient personality dimensions, coping styles, and outcomes of GC. We recruited patients from a psychiatric genetics clinic who had - in the prior 7 years - completed the GC Outcomes Scale (GCOS, a measure of empowerment) immediately prior to, and approximately one month after their appointment, and asked them to complete validated measures of personality and coping style. Interactions between each personality dimension or coping style and GCOS score were assessed using mixed-effects linear regression models. Among the 169 participants, GCOS score increased by an average of 16.48 points (SD = 12.59). Though extraversion, conscientiousness, neuroticism, and all three coping styles significantly predicted GCOS score (p < 0.02), there was no relationship between these variables and time. For example, though a high score on conscientiousness predicted higher GCOS scores, it did not predict greater change in GCOS - people with higher scores on this dimension of personality had higher GCOS scores both pre- and post- GC. These preliminary data suggest that genetic counseling may increase empowerment regardless of personality dimensions and coping styles.

Genetic insights into childhood-onset schizophrenia: The yield of clinical exome sequencing

Childhood-onset schizophrenia (COS) is a rare form of schizophrenia with an onset prior to 13 years of age. Although genetic factors play a role in COS etiology, only a few causal variants have been reported to date. This study presents a diagnostic exome sequencing (ES) in 37 Israeli Jewish families with a proband diagnosed with COS. By implementing a trio/duo ES approach and applying a well-established diagnostic pipeline, we detected clinically significant variants in 7 probands (19 %). These single nucleotide variants and indels were mostly inherited. The implicated genes were ANKRD11, GRIA2, CHD2, CLCN3, CLTC, IGF1R and MICU1. In a secondary analysis that compared COS patients to 4721 healthy controls, we observed that patients had a significant enrichment of rare loss of function (LoF) variants in LoF intolerant genes associated with developmental diseases. Taken together, ES could be considered as a valuable tool in the genetic workup for COS patients.

Impacts of Learning One’s Own Genetic Susceptibility to Mental Disorders

Genomic research is rapidly advancing, and personalized genetic risk information about various mental disorders is likely to become readily available for many individuals. Although genetic profiling is intended to improve individually tailored treatments, knowing one’s genetic risks or lack thereof can have unintended consequences. Upon learning that they have elevated genetic risks for a mental disorder (e.g., depression), people may become more pessimistic about their prognosis and misremember their symptoms as being more serious because they misconceive genes as immutable and defining of their identity. Upon learning that they are not genetically predisposed to a mental disorder (e.g., alcohol use disorder), people may underplay the downstream ramifications of the symptoms even when they are currently experiencing those symptoms. Possible interventions to counteract these problems and suggestions for future research are also discussed.

Psychiatric genetic counseling: A survey of Australian genetic counselors' practice and attitudes

Genetic counseling plays a critical role in supporting individuals and their families' adaption to psychiatric conditions, addressing the multifactorial nature of these conditions in a personally meaningful and empowering way. Yet data related to the practice and attitudes of Australian genetic counselors about psychiatric genetic counseling (PGC) is limited. This survey investigated the practice of Australian genetic counselors, and their attitudes toward PGC. Genetic counselors (N = 393) were invited to participate in an anonymous online survey between March and May 2022. Forty-four genetic counselors (response rate = 11%) from Australia and New Zealand responded. No respondents practice in psychiatric genetics as their speciality area; most respondents do not see any patients where the primary indication is a personal and/or family history of psychiatric disorders (91%). Greater than half of respondents (56%) believed there was sufficient evidence to support PGC, and 64% enquire about personal and/or family history of psychiatric disorders, but only 25% provide genetic counseling on this topic. Most respondents do not feel confident providing risk assessments for psychiatric disorders (72%), while the majority expressed interest in attending specialist training (95%), and in incorporating PGC into future practice (77%). Australian genetic counselors would benefit from psychiatric genetic education and training, and establishment of specialized PGC services would address this gap in patient care, while providing opportunities for genetic counselors to gain skills and experience in PGC.

Healthcare decision makers' perspectives on the creation of new genetic counselor positions in North America: Exploring the case for psychiatric genetic counseling

Mental illnesses are common and highly heritable. Patients and their families want and benefit from receiving psychiatric genetic counseling (pGC). Though the pGC workforce is among the smallest of genetic counseling (GC) specialties, genetic counselors (GCs) want to practice in this area. A major barrier to the expansion of the pGC workforce is limited availability of advertised positions, but it remains unclear why this is the case. We used a qualitative approach to explore drivers for and barriers to the creation of GC positions (including pGC) at large centralized genetic centers in the United States and Canada that offer multiple specialty GC services. Individuals with responsibilities for making decisions about creating new clinical GC positions were interviewed using a semi-structured guide, and an interpretive description approach was used for inductive data analysis. From interviews with 12 participants, we developed a theoretical model describing how the process of creating new GC positions required institutional prioritization of funding, which was primarily allocated according to physician referral patterns, which in turn were largely driven by availability of genetic testing and clinical practice guidelines. Generating revenue for the institution, improving physician efficiency, and reinforcing institutional mission were all regarded as valued outcomes that bolstered prioritization of funding for new GC positions. Evidence of patient benefit arising from new GC positions (e.g., pGC) seemed to play a lesser role. These findings highlight the tension between how institutions value GC (generating revenue, reacting to genetic testing), and how the GC profession sees its value (providing patient benefit, focus on counseling).

Psychiatric polygenic risk scores: Child and adolescent psychiatrists' knowledge, attitudes, and experiences

Psychiatric polygenic risk scores (PRS) have potential utility in psychiatric care and prevention, but there are concerns about their implementation. We surveyed 960 US-based practicing child and adolescent psychiatrists' (CAP) about their experiences, perspectives, and potential uses of psychiatric PRS. While 23% of CAP reported that they had never heard of PRS, 10 % of respondents have had a patient/family bring PRS to them and 4% have generated PRS for patients. Though 25% stated they would request PRS if a patient/caregiver asked, 35% indicated that nothing would prompt them to request PRS. Most respondents (54%) believed psychiatric PRS are currently at least slightly useful and 87% believed they will be so in 5 years. More than 70% indicated they would take action in response to a child with a top fifth percentile psychiatric PRS but no diagnosis: 48% would increase monitoring of symptoms, 42% would evaluate for current symptoms, and 4% would prescribe medications. Yet, most respondents were concerned that high-PRS results could lead to overtreatment and negatively impact patients' emotional well-being. Findings indicate emerging use of psychiatric PRS within child and adolescent psychiatry in the US. It is critical to examine the ethical and clinical challenges that PRS may generate and begin efforts to promote their informed and responsible use.

Concerns about the use of polygenic embryo screening for psychiatric and cognitive traits

Private companies have begun offering services to allow parents undergoing in-vitro fertilisation to screen embryos for genetic risk of complex diseases, including psychiatric disorders. This procedure, called polygenic embryo screening, raises several difficult scientific and ethical issues, as discussed in this Personal View. Polygenic embryo screening depends on the statistical properties of polygenic risk scores, which are complex and not well studied in the context of this proposed clinical application. The clinical, social, and ethical implications of polygenic embryo screening have barely been discussed among relevant stakeholders. To our knowledge, the International Society of Psychiatric Genetics is the first professional biomedical organisation to issue a statement regarding polygenic embryo screening. For the reasons discussed in this Personal View, the Society urges caution and calls for additional research and oversight on the use of polygenic embryo screening.

The impact of psychiatric disorders on caregivers: An integrative predictive model of burden, stigma, and well-being

PURPOSE

The study investigates the predictors of caregivers' experienced burden, stigma, and well-being, when looking after family members diagnosed with a psychiatric disorder.

DESIGN AND METHODS

This cross-sectional study included 168 caregivers; perceived burden, stigma, well-being, knowledge, illness perception, and medical variables were assessed.

FINDINGS

A number of correlates of burden, stigma, and well-being have been identified and are being discussed. The integrative predictive model showed that the caregiver's emotional representation of illness best predicts burden (β = 0.38, p < 0.001), stigma (β = 0.53, p < 0.001) and well-being (β = -0.36, p < 0.001).

PRACTICE IMPLICATIONS

Our results can enable health professionals to tailor psychosocial interventions addressed to family members of individuals living with a psychiatric condition.

Psychiatric genetic counseling for people with copy number variants associated with psychiatric conditions

22q11.2 deletion is one of the most well-known copy number variants (CNVs) associated with developing a psychiatric condition (e.g. schizophrenia), but there is a growing list of other CNVs which also confer substantial risk for developing psychiatric conditions. With increased use of chromosome microarray and exome sequencing, the frequency with which these CNVs are detected is increasing. While individuals with such CNVs often receive genetic counseling, research shows that associated psychiatric conditions are less often addressed - clinicians tend to focus on the non-psychiatric manifestations of the CNV. This represents an important service gap for people with these CNVs and their families, as research shows that genetic counseling about psychiatric illness can produce meaningful positive outcomes for people, including increases in empowerment, and self-efficacy. Therefore, there is a need to ensure that individuals with psychiatric condition-associated CNVs are being counseled about these manifestations of their condition in a way that can promote best outcomes. In this paper we describe the process of providing genetic counseling in two clinical scenarios in which a psychiatric susceptibility CNV is identified: 1) in an individual who has not been diagnosed with a psychiatric condition and 2) in an individual with an established psychiatric condition.

Genetics of Attention-Deficit Hyperactivity Disorder

Attention-Deficit Hyperactivity Disorder (ADHD) has long been recognized as being a highly heritable condition and our understanding of the genetic contributions to ADHD has grown over the past few decades. This chapter will discuss the studies that have examined its heritability and the efforts to identify specific genetic risk-variants at the molecular genetic level. We outline the various techniques that have been used to characterize genetic contributions to ADHD, describing what we have learnt so far, what there is still to learn and the methodologies that can be used to further our knowledge. In doing so we will discuss research into rare and common genetic variants, polygenic risk scores, and gene-environment interplay, while also describing what genetic studies have revealed about the biological processes involved in ADHD and what they have taught us about the overlap between ADHD and other psychiatric and somatic disorders. Finally, we will discuss the strengths and limitations of the current methodologies and clinical implications of genetic research to date.

The stepwise process of integrating a genetic counsellor into primary care

Genetic services have historically been housed in tertiary care, requiring referral, which can present access barriers. While integrating genetics into primary care could facilitate access, many primary care physicians lack genomics expertise. Integrating genetic counsellors (GCs) into primary care could theoretically address these issues, but little is known about how to do this effectively. To understand and describe the process of integrating a GC into a multidisciplinary primary care setting, we qualitatively explored the perceptions, attitudes and reactions of existing team members prior to, and after the introduction of a GC. Semi-structured interviews were conducted immediately prior to (T1), and 9 months after (T2), the GC joining the clinic. Interviews were recorded, transcribed verbatim and analyzed concurrently with data collection using interpretive description. Twenty-four interviews were conducted with 17 participants (13 at T1, 11 at T2). Participants described several distinct, progressive stages of interaction with the GC: Disinterest or Resistance, Pre-Collaboration, Initial Collaboration, and Effective Collaboration/Integration of the GC into the team. At each stage, specific needs had to be met in order to advance to the next stage of collaboration. A variety of barriers and facilitators attended movement between different stages of the model. The Stepwise Process of Integration Model describes the process through which primary care staff and clinicians integrate a GC into their practice. The insight provided by this model could be used to facilitate more effective integration of GCs into other primary care settings.
