Preferences Regarding Targeted Education and Risk Assessment in People with a Family History of Major Depressive Disorder

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.

Information needs and sources of information among people with depression and anxiety: a scoping review

BACKGROUND

Previous studies have identified substantial unmet information needs in people with depression and anxiety. Sufficient information about the disorder, treatment, available services, and strategies for self-management is essential as it may influence quality of care and patients' quality of life. This scoping review aimed to provide a broad overview of information needs of people with depression and anxiety as well as the sources that they use to seek this information.

METHODS

We included all primary research published in English that investigated information needs or information sources in people with depression or anxiety, with no restrictions imposed on the study design, location, setting, or participant characteristics. Six electronic databases (MEDLINE, Embase, PsycINFO, CINAHL, LISTA, Web of Science) and the grey literature (Google and Google Scholar) were searched for relevant studies published up to November 2021. Two reviewers independently screened articles and extracted data. Narrative synthesis was performed to identify key themes of information needs and information sources. Factors associated with information needs/sources such as demographic variables and symptom severity were also identified.

RESULTS

Fifty-six studies (comprising 8320 participants) were included. Information needs were categorised into seven themes, including general facts, treatment, lived experience, healthcare services, coping, financial/legal, and other information. The most frequently reported needs in both people with depression and anxiety were general facts and treatment information. Subclinical samples who self-reported depressive/anxious symptoms appeared less interested in treatment information than patients with clinical diagnoses. Information sources were summarised into five categories: health professionals, written materials, media, interpersonal interactions, and organisational resources. Health professionals and media (including the internet) were the most frequently adopted and preferred sources. Although few studies have examined factors associated with information needs and information sources, there is preliminary evidence that symptom severity and disease subtypes are related to information needs/sources, whereas findings on demographic factors were mixed.

CONCLUSIONS

Information needs appear to be high in people with depression and anxiety. Future research should examine differences between subgroups and associated factors such as the treatment course. Personalised information provision strategies are also needed to customise information according to individual needs and patient profiles.

TRIAL REGISTRATION

The protocol of this scoping review was registered on Open Science Framework (OSF; link: https://doi.org/10.17605/OSF.IO/DF2M6 ).

Data sharing in the age of predictive psychiatry: an adolescent perspective

BACKGROUND

Advances in genetics and digital phenotyping in psychiatry have given rise to testing services targeting young people, which claim to predict psychiatric outcomes before difficulties emerge. These services raise several ethical challenges surrounding data sharing and information privacy.

OBJECTIVES

This study aimed to investigate young people's interest in predictive testing for mental health challenges and their attitudes towards sharing biological, psychosocial and digital data for such purpose.

METHODS

Eighty UK adolescents aged 16-18 years took part in a digital role-play where they played the role of clients of a fictional predictive psychiatry company and chose what sources of personal data they wished to provide for a risk assessment. After the role-play, participants reflected on their choices during a peer-led interview.

FINDINGS

Participants saw multiple benefits in predictive testing services, but were highly selective with regard to the type of data they were willing to share. Largely due to privacy concerns, digital data sources such as social media or Google search history were less likely to be shared than psychosocial and biological data, including school grades and one's DNA. Participants were particularly reluctant to share social media data with schools (but less so with health systems).

CONCLUSIONS

Emerging predictive psychiatric services are valued by young people; however, these services must consider privacy versus utility trade-offs from the perspective of different stakeholders, including adolescents.

CLINICAL IMPLICATIONS

Respecting adolescents' need for transparency, privacy and choice in the age of digital phenotyping is critical to the responsible implementation of predictive psychiatric services.

Leveraging electronic health records to inform genetic counseling practice surrounding psychiatric disorders

Since nearly one-fifth of US adults have a psychiatric disorder, genetic counselors (GCs) will see many patients with these indications. However, GCs' reports of inadequate preparation and low confidence in providing care for patients with psychiatric disorders can limit their ability to meet patient's needs. How frequently psychiatric disorders present in GC sessions is currently unclear. Here, we used deidentified electronic health records (EHR) to estimate the prevalence of 16 psychiatric disorders. In 7,155 GC patients, 34% had a diagnostic code associated with a psychiatric disorder; 23% with anxiety/phobic disorders; 21% with mood disorder/depression; 5% with attention deficit hyperactivity disorder (ADHD); and 1% with psychotic disorders. Compared to 415,709 demographically matched controls, GC patients showed a significantly higher prevalence of psychiatric disorders (GC prevalence: 34%, matched prevalence: 30%, p-value < 0.0001) driven predominantly by anxiety disorder, major depressive disorder, generalized anxiety disorder, and ADHD. Within GC specialties (prenatal: n = 2,674, cancer: n = 1,474, pediatric: n = 465), only pediatric GC patients showed a significant increase in psychiatric disorder prevalence overall (pediatric GC prevalence: 28%, matched prevalence: 13%, p-value < 0.0001). However, significant evidence of increased prevalence existed for generalized anxiety disorder (prenatal GC prevalence 6.4%, matched prevalence: 4.9%, p-value < 0.0001), anxiety disorders (cancer GC prevalence: 26%, matched prevalence: 21%, p-value < 0.0001 and pediatric GC prevalence: 12%, matched prevalence: 5.5%), and ADHD (pediatric GC prevalence: 18%, matched prevalence: 7.9%, p-value < 0.0001). These results highlight the need for additional guidance around care for patients with psychiatric disorders and the value of EHR-based research in genetic counseling.

Perceptions of genetic risk, testing, and counseling among individuals with eating disorders

OBJECTIVE

Eating disorders develop as a result of genetic and environmental factors. Given that they are multifactorial conditions with a genetic component, they fall within the scope of practice for genetic counseling, but people with these conditions are rarely referred. The purpose of this study was to explore the perceptions of causes of eating disorders, recurrence risk, and interest in genetic counseling and testing among individuals with eating disorders.

METHOD

An online survey comprising both multiple choice and free form text questions, vignettes about genetic counseling, and the ED100K (validated eating disorder diagnostic questionnaire) was shared via support organizations and prominent bloggers in the eating disorders community to recruit individuals with a personal history of an eating disorder from November 2018 to February 2019.

RESULTS

In total, 107 participants completed the survey. They perceived that both experiences and genetics were important factors in the development of their eating disorder. All responding participants overestimated the risk for recurrence of eating disorders in children, often by a large margin, and a notable minority reported that their experience with an eating disorder had a negative influence on their childbearing decisions. After imagined experience of genetic counseling, participants reported significantly decreased feelings of stigma, shame, and guilt. Most participants expressed interest in genetic counseling; fewer were interested in genetic testing.

DISCUSSION

Genetic counseling may benefit individuals with eating disorders by providing accurate recurrence risk information and reducing feelings of guilt, stigma, and shame, which may in turn encourage earlier support seeking and recovery.

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

Psychiatric disorders, such as schizophrenia, depression, anxiety, and bipolar disorder, are common conditions that arise as a result of complex and heterogeneous combinations of genetic and environmental factors. In contrast to childhood neurodevelopmental conditions such as autism and intellectual disability, there are no clinical practice guidelines for applying genetic testing in the context of these conditions. But genetic counseling and genetic testing are not synonymous, and people who live with psychiatric disorders and their family members are often interested in what psychiatric genetic counseling can offer. Further, research shows that it can improve outcomes like empowerment for this population. Despite this, psychiatric genetic counseling is not yet routinely or widely offered. This review describes the state of the evidence about the process and outcomes of psychiatric genetic counseling, focusing on its clinical implications and remaining research gaps.

A cluster randomized controlled trial of an online psychoeducational intervention for people with a family history of depression

BACKGROUND

People with a family history of major depressive disorder (MDD) or bipolar disorder (BD) report specific psychoeducational needs that are unmet by existing online interventions. This trial aimed to test whether an interactive website for people at familial risk for depression (intervention) would improve intention to adopt, or actual adoption of, depression prevention strategies (primary outcome) and a range of secondary outcome measures.

METHODS

In this cluster randomised trial, primary care practises were randomised to either provide the link to the intervention or the control website. Primary health care attendees were invited by letter to opt into this study if they had at least one first-degree relative with MDD or BD and were asked to complete online questionnaires at baseline and 2-week follow-up.

RESULTS

Twenty general practices were a randomized, and 202 eligible patients completed both questionnaires. Thirty-nine (19.3%) of participants were male and 163 (80.7%) female. At follow-up, compared to controls, the intervention group: (i) were more likely to intend to undergo, or to have actually undergone, psychological therapies (OR = 5.83, 95% CI: 1.58-21.47, p = .008); (ii) had better knowledge of depression risk factors and prevention strategies (mean difference = 0.47, 95% CI: 0.05-0.88, p = .029); and (iii) were more likely to accurately estimate their lifetime risk of developing BD (mean difference = 11.2, 95% CI: -16.52- -5.73, p < .001). There were no statistically significant between-group differences in change from baseline to follow up for any of the remaining outcome measures (Patient Health Questionnaire, Perceived Devaluation-Discrimination Questionnaire and Perceived Risk of Developing MDD).

CONCLUSION

The opt-in nature of the study may have led to participation bias, e.g. underrepresentation of males, and hence may limit generalisability to the broader population at familial risk for depression. This is the first website internationally focusing specifically on informational needs of those at familial risk of depression. Our interactive website can play an important role in improving the outcomes of individuals at familial risk for depression. Testing the intervention in other settings (e.g. psychology, psychiatry, genetic counselling) appears warranted.

TRIAL REGISTRATION

The study was prospectively registered with the Australian and New Zealand Clinical Trials Group (Registration no: ACTRN12613000402741 ).

Should we intervene at stage 0? A qualitative study of attitudes of asymptomatic youth at increased risk of developing bipolar disorders and parents with established disease

BACKGROUND

Studies of potential interventions for asymptomatic individuals at risk of severe mental disorders (ie, clinical stage 0) have focused on genetic counselling or the views of adults with established disease. No study has interviewed youth at risk of bipolar disorders (BD).

METHODS

Qualitative analysis of interviews with asymptomatic adolescent offspring of adults with BD (OSBD = 7) and unrelated parents with bipolar disorders (PBD = 6) to examine manifest and latent themes in the dialogue.

RESULTS

Core themes in both groups were ignorance regarding the magnitude of risk of BD onset in offspring and greater concerns for the health of other family members than for oneself. Parents expressed anxieties in coping with the uncertainty about whether their children would inherit BD and their desire to reduce this risk was partly driven by guilt and their sense of responsibility; PBD favoured the introduction of specialized clinical OSBD services. In contrast, the priority for OSBD was advice on coping with a parent with BD; OSBD favoured access to generic non-clinical peer group support, which they perceived as less stigmatizing than specialist services.

CONCLUSION

The study highlights that youth at risk of BD should be allowed to express their ideas on what interventions they believe are likely to be most beneficial for them, as their views may differ from other advocates who are routinely consulted, such as PBD. A noteworthy finding was that OSBD thought that being included in the clinical dialogue about their parents' BD would decrease rather than increase their stress levels.

A Psycho-Educational Intervention for People with a Family History of Depression: Pilot Results

We developed and pilot-tested the first online psycho-educational intervention that specifically targets people with a family history of depression ('LINKS'). LINKS provides genetic risk information and evidence-rated information on preventive strategies for depression and incorporates a risk assessment tool and several videos using professional actors. LINKS was pilot-tested in the general practitioner (GP) setting. The patient sample included people with a family history of at least one first-degree relative (FDR) with major depressive disorder (MDD) or bipolar disorder (BD). Patients attending participating GP practices were invited to enroll in the study by letter from their GP. Patients who self-identified as having at least one first-degree relative (FDR) with MDD or BD were eligible. Patients completed questionnaires, pre-post viewing LINKS, with measures assessing satisfaction, relevance, emotional impact and perceived improvement of understanding. Six GP practices participated, and 24 patients completed both questionnaires. Of these, all reported that they were satisfied or very satisfied with LINKS, and 74 % reported that LINKS met their expectations, and 21 % that it exceeded their expectations. LINKS was judged highly acceptable by this sample of GP attendees, and results indicate that an assessment of its effectiveness in a larger controlled trial is warranted.
