A Randomized Trial of Two Remote Health Care Delivery Models on the Uptake of Genetic Testing and Impact on Patient-Reported Psychological Outcomes in Families With Pancreatic Cancer: The Genetic Education, Risk Assessment, and Testing (GENERATE) Study

BACKGROUND & AIMS

Genetic testing uptake for cancer susceptibility in family members of patients with cancer is suboptimal. Among relatives of patients with pancreatic ductal adenocarcinoma (PDAC), The GENetic Education, Risk Assessment, and TEsting (GENERATE) study evaluated 2 online genetic education/testing delivery models and their impact on patient-reported psychological outcomes.

METHODS

Eligible participants had ≥1 first-degree relative with PDAC, or ≥1 first-/second-degree relative with PDAC with a known pathogenic germline variant in 1 of 13 PDAC predisposition genes. Participants were randomized by family, between May 8, 2019, and June 1, 2021. Arm 1 participants underwent a remote interactive telemedicine session and online genetic education. Arm 2 participants were offered online genetic education only. All participants were offered germline testing. The primary outcome was genetic testing uptake, compared by permutation tests and mixed-effects logistic regression models. We hypothesized that Arm 1 participants would have a higher genetic testing uptake than Arm 2. Validated surveys were administered to assess patient-reported anxiety, depression, and cancer worry at baseline and 3 months postintervention.

RESULTS

A total of 424 families were randomized, including 601 participants (n = 296 Arm 1; n = 305 Arm 2), 90% of whom completed genetic testing (Arm 1 [87%]; Arm 2 [93%], P = .014). Arm 1 participants were significantly less likely to complete genetic testing compared with Arm 2 participants (adjusted ratio [Arm1/Arm2] 0.90, 95% confidence interval 0.78-0.98). Among participants who completed patient-reported psychological outcomes questionnaires (Arm 1 [n = 194]; Arm 2 [n = 206]), the intervention did not affect mean anxiety, depression, or cancer worry scores.

CONCLUSIONS

Remote genetic education and testing can be a successful and complementary option for delivering genetics care. (Clinicaltrials.gov, number NCT03762590).

Understanding Social, Cultural, and Religious Factors Influencing Medical Decision-Making on BRCA1/2 Genetic Testing in the Orthodox Jewish Community

INTRODUCTION

Although the prevalence of a pathogenic variant in the BRCA1 and BRCA2 genes is about 1:400 (0.25%) in the general population, the prevalence is as high as 1:40 (2.5%) among the Ashkenazi Jewish population. Despite cost-effective preventive measures for mutation carriers, Orthodox Jews constitute a cultural and religious group that requires different approaches to BRCA1 and BRCA2 genetic testing relative to other groups. This study analyzed a dialog of key stakeholders and community members to explore factors that influence decision-making about BRCA1 and BRCA2 genetic testing in the New York Orthodox Jewish community.

METHODS

Qualitative research methods, based on Grounded Theory and Narrative Research, were utilized to analyze the narrative data collected from 49 key stakeholders and community members. A content analysis was conducted to identify themes; inter-rater reliability was 71%.

RESULTS

Facilitators of genetic testing were a desire for preventive interventions and education, while barriers to genetic testing included negative emotions, feared impact on family/romantic relationships, cost, and stigma. Views differed on the role of religious leaders and healthcare professionals in medical decision-making. Education, health, and community were discussed as influential factors, and concerns were expressed about disclosure, implementation, and information needs.

CONCLUSION

This study elicited the opinions of Orthodox Jewish women (decision-makers) and key stakeholders (influencers) who play critical roles in the medical decision-making process. The findings have broad implications for engaging community stakeholders within faith-based or culturally distinct groups to ensure better utilization of healthcare services for cancer screening and prevention designed to improve population health.

Parental monitoring for type 1 diabetes in genetically at-risk young children: The TEDDY study

OBJECTIVE

We examined parental diabetes monitoring behaviors in a cohort of children at increased genetic risk for type 1 diabetes. We hypothesized that being informed of a positive islet autoantibody (IA) would increase monitoring behaviors.

RESEARCH DESIGN AND METHODS

The Environmental Determinants of Diabetes in the Young (TEDDY) study follows 8676 children with high-risk human leucocyte antigen-DQ genotypes from birth to age 15, including general population (GP) children and those with a first-degree relative (FDR) with diabetes. Data on parental monitoring behaviors were solicited yearly. Serum samples were tested for IA and parents were informed of child results. We examined parental monitoring behaviors during the first 7 years of TEDDY.

RESULTS

In IA- children, the most common monitoring behavior was participating in TEDDY study tasks; up to 49.8% and 44.2% of mothers and fathers, respectively, reported this. Among FDRs, 7%-10% reported watching for diabetes symptoms and 7%-9% reported monitoring the child's glucose, for mothers and fathers, respectively. After IA+ notification, all monitoring behaviors significantly increased in GP parents; only glucose monitoring increased in FDR parents and these behaviors continued for up to 4 years. FDR status, accurate diabetes risk perception, and anxiety were associated with glucose monitoring in IA+ and IA- cohorts.

CONCLUSIONS

Many parents view TEDDY participation as a way to monitor for type 1 diabetes, a benefit of enrollment in a longitudinal study with no prevention offered. IA+ notification increases short- and long-term monitoring behaviors. For IA- and IA+ children, FDR parents engage in glucose monitoring, even when not instructed to do so.

The Psychiatric Genetic Data of Children in Proceedings to Terminate Parental Rights

The introduction of psychiatric genetic evidence in court proceedings to terminate parental rights raises concerns that such information will result in misconceived assumptions about the child's mental health trajectory and unjust rulings on termination of parental rights. We conducted an online vignette-based survey with a nationally representative sample of adults from the general public (n = 300 respondents) to assess their views on how evidence about a child's psychiatric genetic makeup may affect key decisions in termination proceedings. Our findings indicate that genetic evidence increased the child's labeling as having a psychiatric disorder, regardless of the presence of symptoms, treatment recommendations, evaluation of prescription medication, and beliefs in treatment efficacy. Genetic evidence alone did not affect whether participants would terminate parental rights, but participants who thought that the child did not have a psychiatric disorder were more likely to terminate in the presence of genetic test results. We conclude that psychiatric genetic evidence in termination proceedings may have unintended consequences, and that measures should be taken to ensure that it does not unfairly affect outcomes.

Young people's moral attitudes and motivations towards direct-to-consumer genetic testing for inherited risk of Alzheimer disease

Purpose

Since the U.S. Food and Drug Administration approved sales of genetic tests for late-onset Alzheimer's disease (LOAD) risk, a heated debate has arisen over whether these tests should indeed be offered online and direct-to-consumer (DTC). As this debate progresses, it is important to understand the ethical perspectives and motivations of young people, who are a key target group for DTC services.

Methods

Thirty-one grandchildren of people with LOAD, aged 16–26, were interviewed about their moral attitudes and motivations with regards to DTC genetic testing for LOAD.

Results

Even though most participants claimed that people should have the right to access these services, they also expressed concerns about potential distress in response to learning about risk, particularly for minors. About a third were interested in testing, primarily to gain self-knowledge regarding one's health; however, face-to-face services were vastly preferred over the online option.

Conclusion

While DTC genetic companies often market their services as a “fun consumer product”, DTC testing for LOAD was largely understood as a serious health screening procedure and a vulnerable moment in the lives of young people in Alzheimer's families. This points to the importance of appropriate standards of information and support to young people pre- and post-testing.

Priority of Risk (But Not Perceived Magnitude of Risk) Predicts Improved Sun-Protection Behavior Following Genetic Counseling for Familial Melanoma

BACKGROUND

Understanding multiple components of risk perceptions is important because perceived risk predicts engagement in prevention behaviors.

PURPOSE

To examine how multiple components of risk perceptions (perceived magnitude of and worry about risk, prioritization of the management of one's risk) changed following genetic counseling with or without test reporting, and to examine which of these components prospectively predicted improvements in sun-protection behavior 1 year later.

METHODS

A prospective, nonrandomized study design was used. Participants were 114 unaffected members of melanoma-prone families who (i) underwent genetic testing for a CDKN2A/p16 mutation (n = 69) or (ii) were at comparably elevated risk based on family history and underwent genetic counseling but not testing (no-test controls, n = 45). Participants reported risk perception components and sun-protection behavior at baseline, immediately following counseling, and 1 month and 1 year after counseling.

RESULTS

Factor analysis indicated three risk components. Carriers reported increased perceived magnitude and priority of risk, but not cancer worry. No-test controls showed no changes in any risk perception. Among noncarriers, priority of risk remained high at all assessments, whereas magnitude of risk and cancer worry decreased. Of the three risk components, greater priority of risk uniquely predicted improved self-reported sun protection 1 year post-counseling.

CONCLUSIONS

Priority of risk (i) seems to be a component of risk perceptions distinguishable from magnitude of risk and cancer worry, (ii) may be an important predictor of daily prevention behavior, and (iii) remained elevated 1 year following genetic counseling only for participants who received a positive melanoma genetic test result.

The Role of Eating Behaviours in Genetic Susceptibility to Obesity

PURPOSE OF REVIEW

Eating behaviours are hypothesised to be the behavioural expression of genetic risk of obesity. In this review, we summarise findings from behavioural genetic research on the association between genetic risk for obesity and validated psychometrics measures of eating behaviours in children and adults (published in the past 10 years).

RECENT FINDINGS

Twin studies have produced some evidence for a shared genetic aetiology underlying body mass index and eating behaviours. Studies using measured genetic susceptibility to obesity have suggested that increased genetic liability for obesity is associated with variation in obesogenic eating behaviours such as emotional and uncontrolled eating. More research on this topic is needed. Especially longitudinal studies using genetically sensitive designs to investigate the direction of genetic pathways between genetic liability of eating behaviours to weight and vice versa, as well as the potential subsequent link to eating disorders.

Effects of genetic information on memory for severity of depressive symptoms

The general public is increasingly aware of the role of genes in causing depression. Recent studies have begun uncovering unintended negative consequences of learning about a person’s genetic susceptibility to disorders. Because people tend to believe that genes determine one’s identity, having genes related to a disorder can be misinterpreted as equivalent to having the disorder. Consequently, learning that a person is genetically predisposed to depression can make people misremember mild depression as more severe. Participants across three experiments read a target vignette about a character displaying mild depressive symptoms, while descriptions of the character’s genetic susceptibility to depression were experimentally manipulated. Participants then read a foil vignette describing a character with more severe depressive symptoms. Afterwards, participants who had learned that the target character was genetically predisposed to depression were comparatively more likely to misremember the target symptoms as being severe, when in fact they were mild. This pattern of results was obtained among both laypeople (Experiments 1 and 2) and practicing master’s-level, but not doctoral-level, mental health clinicians (Experiment 3). Given that depression is diagnosed primarily based on a person’s memory of depressive symptoms, the current findings suggest that genetic information about depression may lead to over-diagnosis of depression.

Genetic risk, incident gastric cancer, and healthy lifestyle: a meta-analysis of genome-wide association studies and prospective cohort study

BACKGROUND

Genetic variants and lifestyle factors have been associated with gastric cancer risk, but the extent to which an increased genetic risk can be offset by a healthy lifestyle remains unknown. We aimed to establish a genetic risk model for gastric cancer and assess the benefits of adhering to a healthy lifestyle in individuals with a high genetic risk.

METHODS

In this meta-analysis and prospective cohort study, we first did a fixed-effects meta-analysis of the association between genetic variants and gastric cancer in six independent genome-wide association studies (GWAS) with a case-control study design. These GWAS comprised 21 168 Han Chinese individuals, of whom 10 254 had gastric cancer and 10 914 geographically matched controls did not. Using summary statistics from the meta-analysis, we constructed five polygenic risk scores in a range of thresholds (p=5 × 10^-4 p=5 × 10^-5 p=5 × 10^-6 p=5 × 10^-7, and p=5 × 10^-8) for gastric cancer. We then applied these scores to an independent, prospective, nationwide cohort of 100 220 individuals from the China Kadoorie Biobank (CKB), with more than 10 years of follow-up. The relative and absolute risk of incident gastric cancer associated with healthy lifestyle factors (defined as not smoking, never consuming alcohol, the low consumption of preserved foods, and the frequent intake of fresh fruits and vegetables), was assessed and stratified by genetic risk (low [quintile 1 of the polygenic risk score], intermediate [quintile 2-4 of the polygenic risk score], and high [quintile 5 of the polygenic risk score]). Individuals with a favourable lifestyle were considered as those who adopted all four healthy lifestyle factors, those with an intermediate lifestyle adopted two or three factors, and those with an unfavourable lifestyle adopted none or one factor.

FINDINGS

The polygenic risk score derived from 112 single-nucleotide polymorphisms (p<5 × 10^-5) showed the strongest association with gastric cancer risk (p=7·56 × 10^-10). When this polygenic risk score was applied to the CKB cohort, we found that there was a significant increase in the relative risk of incident gastric cancer across the quintiles of the polygenic risk score (p_trend<0·0001). Compared with individuals who had a low genetic risk, those with an intermediate genetic risk (hazard ratio [HR] 1·54 [95% CI 1·22-1·94], p=2·67 × 10^-4) and a high genetic risk (2·08 [1·61-2·69], p<0·0001) had a greater risk of gastric cancer. A similar increase in the relative risk of incident gastric cancer was observed across the lifestyle categories (p_trend<0·0001), with a higher risk of gastric cancer in those with an unfavourable lifestyle than those with a favourable lifestyle (2·03 [1·46-2·83], p<0·0001). Participants with a high genetic risk and a favourable lifestyle had a lower risk of gastric cancer than those with a high genetic risk and an unfavourable lifestyle (0·53 [0·29-0·99], p=0·048), with an absolute risk reduction of 1·12% (95% CI 0·62-1·56).

INTERPRETATION

Chinese individuals at an increased risk of incident gastric cancer could be identified by use of our newly developed polygenic risk score. Compared with individuals at a high genetic risk who adopt an unhealthy lifestyle, those who adopt a healthy lifestyle could substantially reduce their risk of incident gastric cancer.

Factors shaping at-risk individuals' decisions to undergo genetic testing for cancer in Asia

This study aims to enrich our understanding of factors influencing medically indicated at-risk individuals' decisions to take genetic tests (or not) in the context of cancer treatment and prevention. While previous studies have explored this topic in communities in Europe and the United States, we know relatively little about the situation in Asia. In this study, we conducted in-depth interviews with 24 women who underwent genetic testing for hereditary breast and ovarian cancer syndromes in Singapore. Grounded theory with thematic analysis was applied. Six encouraging and three discouraging factors are identified in the analysis. The six encouraging factors are: desire to create awareness for self and family; perceived benefits for self and family; strong family history of cancer; presence of family support; medical professional recommendation and adequate amount of time to consider undertaking the test. The three discouraging factors are: high costs of tests; perceived lack of ability to cope with test results; and insufficient information about genetic testing. Taken together, the findings in this study add to the current literature by providing empirical evidence regarding the importance of holding family included pre-test counselling and providing adequate time for patients to decide to undergo genetic testing for hereditary cancer syndromes.

The D2 dopamine receptor (DRD2) gene is associated with co-morbid depression, anxiety and social dysfunction in untreated veterans with post-traumatic stress disorder

Objective.

To identify clusters of patients with post-traumatic stress disorder (PTSD) according to symptom profile and to examine the association of the A1 allele of the D2 dopamine receptor (DRD2) gene with these clusters.

Method.

Fifty-seven untreated Caucasian Vietnam veterans with PTSD were administered the General Health Questionnaire-28 (GHQ) and the Mississippi Scale for combat-related PTSD. DRD2 allelic status was determined by PCR.

Results.

Subjects with the DRD2 Al allele compared to those without this allele had significantly higher scores on GHQ 2 (anxiety/insomnia), GHQ 3 (social dysfunction) and GHQ 4 (depression). Cluster analysis of the GHQ data identified two primary groups. A high psychopathology cluster (cluster 3), featured by high co-morbid levels of somatic concerns, anxiety/insomnia, social dysfunction and depression, and a low psychopathology cluster (cluster 1), manifested by the reverse pattern. Scores in each of the four GHQ groups were significantly higher in cluster 3 than cluster 1, as was Mississippi Scale PTSD score. DRD2 A1 allele veterans compared to those without this allele were significantly more likely to be found in the high than the low psychopathology cluster group.

Conclusions.

DRD2 variants are associated with severe co-morbid psychopathology in PTSD subjects.

Familial aggregation of depression, but no familial aggregation of individual depressive symptoms

Background

Familial aggregation of major depression might indicate a genetic liability for the disorder. The complete disorder or, alternatively, only some individual symptoms might be inherited. Under the latter condition, an increased frequency of inherited symptoms might consecutively increase the likelihood to reach the threshold for depression in relatives and, thus, might cause the familial aggregation of depression. Up to now, no study investigated the possibility of a relationship between individual depressive symptoms and the familial aggregation of depression.

Methods

The familial aggregation of early-onset depression (age-at-onset < 60 years, EOD) but less so of late-onset depression (LOD) has been shown in this sample. To assess the hypothesis of an inheritance of individual depressive symptoms as a possible cause of the familial aggregation of depression, frequencies of symptoms were compared in relatives of depressed patients and of controls using forward logistic regression analyses.

Results

Some individual depressive symptoms showed clustering in relatives of patients with depression, but the pattern of inheritance was inconsistent, i.e. the clustering of symptoms was different between non-depressed and depressed relatives of patients with EOD and LOD, respectively. No intra-familial clustering of specific depressive symptoms within families of depressed subjects could be observed.

Conclusions

Due to the inconsistencies in the clustering of individual symptoms in non-depressed and depressed relatives and the lack of intra-familial clustering, the familial aggregation of depression is unlikely to be caused by the aggregation of individual depressive symptoms. An inheritance of the vulnerability for complete depressive disorders influenced by environmental factors is more likely.

Temperament and character dimensions of the relatives of schizophrenia patients and controls: The relationship between schizotypal features and personality

Purpose

Previous findings indicated that schizophrenia patients might have a different personality structure from the general population on several dimensions of temperament and character. Some authors proposed that HA might be a marker of underlying genetic vulnerability to schizophrenia. Studies on high-risk subjects and first degree relatives of patients is essential to test the value of a measure as a marker of genetic vulnerability to a disease. Few studies tested the biopsychosocial model of personality on unaffected relatives of schizophrenia.

Subjects and methods

We compared the Temperament and Character (TCI) profiles of 94 first degree relatives of schizophrenia and 75 controls. We also investigated the relationship between schizotypy and TCI dimensions in the study sample.

Results

The harm avoidance scores of the relatives of schizoprenia patients with schizotypal features were significantly higher. Self transcendence scores were also significantly higher among relatives with schizotypal features. In contrast, the relatives of the patients with schizophrenia who did not have schizotypal features had higher SD and C scores than the control group.

Discussion and conclusion

This finding is consistent with the previous findings which suggested harm avoidance as a vulnerability indicator of schizophrenia. Some character features like self transcendence might be also associated with schizotypal features.

Obstetric complications in patients with schizophrenia and their unaffected siblings

Objective

We sought to explore whether obstetric complications (OCs) are more likely to occur in the presence of familial/genetic susceptibility for schizophrenia or whether they themselves represent an independent environmental risk factor for schizophrenia.

Methods

The presence of OCs was assessed through maternal interview on 216 subjects, comprising 36 patients with schizophrenia from multiply affected families, 38 of their unaffected siblings, 31 schizophrenic patients with no family history of psychosis, 51 of their unaffected siblings and 60 normal comparison subjects. We examined the familiality of OCs and whether OCs were commoner in the patient and sibling groups than in the control group.

Results

OCs tended to cluster within families, especially in multiply affected families. Patients with schizophrenia, especially those from multiply affected families, had a significantly higher rate of OCs compared to normal comparison subjects, but there was no evidence for an elevated rate of OCs in unaffected siblings.

Conclusion

Our data provides little evidence for a link between OCs and genetic susceptibility to schizophrenia. If high rates of OCs are related to schizophrenia genes, this relationship is weak and will only be detected by very large sample sizes.

Stability of Thought Disorder Index among high-risk and low-risk adoptees in the Finnish adoptive family study of schizophrenia

The aim of the study was to evaluate whether thought disorders are stable, trait-like features specific to subjects who have a genetic liability to schizophrenia or a psychiatric disorder. The thought disorders of adoptees genetically at high risk (HR) or low risk (LR) for schizophrenia from the Finnish adoptive family study of schizophrenia were evaluated twice at a mean interval of 11 years, using the sum of the Thought Disorder Index (TDI) scores on the Rorschach (TDR). At the initial assessment, the mean TDR scores of women were significantly higher than those of men, while no association between genetic risk and psychiatric status or their interactions with the TDR scores at baseline were found. The main finding was that the initial TDR scores statistically significantly predicted the TDR scores at follow-up, thus indicating the stability of thought disorder over time. However, neither genetic or psychiatric status nor gender or any interaction between these variables associated with TDR at follow-up.

Differentiation of adoptees at high versus low genetic risk for schizophrenia by adjusted MMPI indices

The aim of this study was to find potential signs of genetic vulnerability to schizophrenia. The differences between adoptees at high genetic risk for schizophrenia (their biological mother had a schizophrenia spectrum disorder) and control adoptees of non-schizophrenia spectrum biological mothers were assessed. The comparisons between these groups were based on the Minnesota Multiphasic Personality Inventory (MMPI) test's subscale scores adjusted by gender, age at MMPI assessment, age at placement into the adoptive family and social class. The subjects were a subsamples of a total of 182 tested adoptees and 136 mentally healthy adoptees in the Finnish Adoptive Family Study. The high-risk group was found to be distinguishable from the low-risk group based on deviant scores on the Hostility, Hypomania and Lie scales. These scales may measure genetic vulnerability and also possibly be indicative of psychometric deviance predicting future onset of schizophrenia.

Research Participants' Attitudes towards Receiving Information on Genetic Susceptibility to Arsenic Toxicity in Rural Bangladesh

BACKGROUND

In human genetics research, it has become common practice for researchers to consider returning genetic information to participants who wish to receive it. Research participants in lower-resource settings may have barriers or competing interests that reduce the benefit or relevance of such information. Thus, the decision to return genetic information in these settings may involve special considerations of participants' interests and preferences. In this project, our goal was to assess Bangladeshi research participants' attitudes towards receiving information regarding genetic susceptibility to the effects of consuming arsenic-contaminated drinking water, a serious environmental health concern in Bangladesh and other countries.

METHODS

We administered a short questionnaire to 200 individuals participating in the Health Effects of Arsenic Longitudinal Study. Associations between survey responses and participant characteristics were estimated using logistic regression.

RESULTS

Overall, 100% of our participants were interested in receiving information regarding their genetic susceptibility to arsenic toxicities, and 91% indicated that being at increased genetic risk would motivate them to make efforts to reduce their exposure. Lower levels of education showed evidence of association with less concern regarding the health effects of arsenic and lower levels of motivation to reduce exposure in response to genetic information.

CONCLUSIONS

Research participants in this low-resource setting appeared interested in receiving information on their genetic susceptibility to arsenic toxicity and motivated to reduce exposure in response to such information. Additional research is needed to understand how best to communicate genetic information in this population and to assess the impact of such information on individuals' behaviors and health.

Familial disclosure by genetic healthcare professionals: a useful but sparingly used legal provision in France

Familial disclosure of genetic information is an important, long-standing ethical issue that still gives rise to much debate. In France, recent legislation has created an innovative and unprecedented procedure that allows healthcare professionals (HCPs), under certain conditions, to disclose relevant information to relatives of a person carrying a deleterious genetic mutation. This article will analyse how HCPs in two medical genetics clinics have reacted to these new legal provisions and show how their reticence to inform the patients' relatives on their behalf leads them to use this option sparingly.

Genetic Counselor and Healthcare Interpreter Perspectives on the Role of Interpreters in Cancer Genetic Counseling

Cancer genetic counseling (CGC) combines psychosocial counseling and genetic education provided by genetic counselors to patients and families who have a history of cancer and are considering or have undergone genetic testing for hereditary cancer syndromes. The quantity and complexity of information provided can be challenging for any patient, but is even more so for those with limited English proficiency (LEP). This exploratory study investigated healthcare interpreters' and genetic counselors' perspectives on the role of interpreters in providing care to LEP patients during CGC. Through a survey of 18 interpreters and conventional content analysis of semi-structured interviews with 11 interpreters and 10 GCs at two California public hospitals, we found that: 1) interpreters viewed their role as patient advocate, cultural broker, and emotional support, not simply a conduit; 2) interpreters were challenged by remote interpretation, lack of genetic knowledge, and the emotional content of encounters; 3) interpreters and GCs held conflicting views of the value of counselors' limited Spanish knowledge; and 4) trust, the foundation of the interpreter-provider dyad, was often lacking. The challenges identified here may result in poor healthcare experiences and outcomes for LEP patients. As genomics becomes more widespread and more LEP patients encounter CGC, the role of healthcare interpreters in facilitating effective communication must be further defined in order to facilitate better working relationships between interpreters and genetic counselors, and optimal communication experiences for patients.

Pancreatic cancer and melanoma related perceptions and behaviors following disclosure of CDKN2A variant status as a research result

PURPOSE

This study examined whether participants who learned research results related to a germline CDKN2A variant known to be associated with increased risk of pancreatic cancer and malignant melanoma would pursue confirmatory testing and cancer screening, share the genetic information with health care providers and family, and change risk perceptions.

METHODS

Participants were pancreas research registry enrollees whose biological sample was tested in a research laboratory for the variant. In total, 133 individuals were invited to learn a genetic research result and participate in a study about the disclosure process. Perceived cancer risk, screening intentions, and behaviors were assessed predisclosure, immediately postdisclosure, and six months postdisclosure.

RESULTS

Eighty individuals agreed to participate and 63 completed the study. Immediately postdisclosure, carriers reported greater intentions to undergo pancreatic cancer and melanoma screening (p values ≤0.024). Seventy-three percent of carriers (47.5% noncarriers) intended to seek confirmatory testing within six months and 20% (2.5% noncarriers) followed through. All participants shared results with ≥1 family member. More carriers shared results with their health care provider than noncarriers (p = 0.028).

CONCLUSION

Recipients of cancer genetic research results may not follow through with recommended behaviors (confirmatory testing, screening), despite stated intentions. The research result disclosure motivated follow-up behaviors among carriers more than noncarriers.

Blast exposure interacts with genetic variant 5HTTLPR to predict posttraumatic stress symptoms in military explosives personnel

The first of its kind, this study determined whether blast exposure interacts with genetic variant 5HTTLPR to predict posttraumatic stress (PTS) symptoms in 78 military explosives operators. In all models, blast-exposed 5HTTLPR S carriers registered definitively higher PTS symptoms in comparison to non-exposed S carriers, as well as exposed and non-exposed LL carriers (all p < 0.01). All findings were robust to confounding influences of age and traumatic brain injury diagnosis. Not only is blast exposure prevalent in EOD personnel, but it also interacts with genetic predisposition to predict trauma symptoms in this unique, at-risk military population.

Differential neural responding to affective stimuli in 6- to 8-year old children at high familial risk for depression: Associations with behavioral reward seeking

OBJECTIVE

Children of depressed parents are at increased risk for psychopathology. One putative mechanism of risk appears to be altered processing of emotion-related stimuli. Although prior work has evaluated how adolescent offspring of depressed parents may show blunted reward processing compared to low-risk youth, there has been less attention to how young children with this familial history may differ from their peers during middle childhood, a period of critical socio-affective development METHOD: The current study evaluated 56 emotionally healthy 6-to 8-year children who were deemed at high-risk (n = 25) or low-risk (n = 31) for depression based on maternal history of depression. Children completed a behavioral reward seeking task in the laboratory and an fMRI paradigm assessing neural response to happy faces, a social reward.

RESULTS

Findings demonstrated that high-risk children showed blunted responding to happy faces in the dorsal striatum compared to low-risk children. Further, lower responding in the dorsal striatum and dorsolateral prefrontal cortex was related to lower behavioral reward seeking, but only in high-risk children.

CONCLUSION

Function within neural reward regions may be altered in high-risk offspring as young as 6- to 8-years of age. Further, neural reward responding may be linked to lower behavioral response to obtain reward in these high-risk offspring.

Joint factorial structure of psychopathology and personality

BACKGROUND

Normative and pathological personality traits have rarely been integrated into a joint large-scale structural analysis with psychiatric disorders, although a recent study suggested they entail a common individual differences continuum.

METHODS

We explored the joint factor structure of 11 psychiatric disorders, five personality-disorder trait domains (DSM-5 Section III), and five normative personality trait domains (the 'Big Five') in a population-based sample of 2796 Norwegian twins, aged 19‒46.

RESULTS

Three factors could be interpreted: (i) a general risk factor for all psychopathology, (ii) a risk factor specific to internalizing disorders and traits, and (iii) a risk factor specific to externalizing disorders and traits. Heritability estimates for the three risk factor scores were 48% (95% CI 41‒54%), 35% (CI 28‒42%), and 37% (CI 31‒44%), respectively. All 11 disorders had uniform loadings on the general factor (congruence coefficient of 0.991 with uniformity). Ignoring sign and excluding the openness trait, this uniformity of factor loadings held for all the personality trait domains and all disorders (congruence 0.983).

CONCLUSIONS

Based on our findings, future research should investigate joint etiologic and transdiagnostic models for normative and pathological personality and other psychopathology.

Psychosocial problems in women attending French, German and Spanish genetics clinics before and after targeted or multigene testing results: an observational prospective study

OBJECTIVES AND SETTING

Advances in multigene panel testing for cancer susceptibility has increased the complexity of counselling, requiring particular attention to counselees' psychosocial needs. Changes in psychosocial problems before and after genetic testing were prospectively compared between genetic test results in women tested for breast or ovarian cancer genetic susceptibility in French, German and Spanish clinics.

PARTICIPANTS AND MEASURES

Among 752 counselees consecutively approached, 646 (86%) were assessed after the initial genetic consultation (T1), including 510 (68%) affected with breast cancer, of which 460 (61%) were assessed again after receiving the test result (T2), using questionnaires addressing genetic-specific psychosocial problems (Psychosocial Aspects of Hereditary Cancer (PAHC)-six scales). Sociodemographic and clinical data were also collected.

RESULTS

Seventy-nine (17.2%), 19 (4.1%), 259 (56.3%), 44 (9.6%) and 59 (12.8%) women received a BRCA1/2, another high/moderate-risk pathogenic variant (PV), negative uninformative, true negative (TN) or variant of uncertain significance result (VUS), respectively. On multiple regression analyses, compared with women receiving another result, those with a VUS decreased more in psychosocial problems related to hereditary predisposition (eg, coping with the test result) (ß=-0.11, p<0.05) and familial/social issues (eg, risk communication) (ß=-0.13, p<0.05), almost independently from their problems before testing. Women with a PV presented no change in hereditary predisposition problems and, so as women with a TN result, a non-significant increase in familial/social issues. Other PAHC scales (ie, emotions, familial cancer, personal cancer and children-related issues) were not affected by genetic testing.

CONCLUSIONS

In women tested for breast or ovarian cancer genetic risk in European genetics clinics, psychosocial problems were mostly unaffected by genetic testing. Apart from women receiving a VUS result, those with another test result presented unchanged needs in counselling in particular about hereditary predisposition and familial/social issues.

A tailored approach towards informing relatives at risk of inherited cardiac conditions: study protocol for a randomised controlled trial

INTRODUCTION

In current practice, probands are asked to inform relatives about the possibility of predictive DNA testing when a pathogenic variant causing an inherited cardiac condition (ICC) is identified. Previous research on the uptake of genetic counselling and predictive DNA testing in relatives suggests that not all relatives are sufficiently informed. We developed a randomised controlled trial to evaluate the effectiveness of a tailored approach in which probands decide together with the genetic counsellor which relatives they inform themselves and which relatives they prefer to have informed by the genetic counsellor. Here, we present the study protocol of this randomised controlled trial.

METHODS

A multicentre randomised controlled trial with parallel-group design will be conducted in which an intervention group receiving the tailored approach will be compared with a control group receiving usual care. Adult probands diagnosed with an ICC in whom a likely pathogenic or pathogenic variant is identified will be randomly assigned to the intervention or control group (total sample: n=85 probands). Primary outcomes are uptake of genetic counselling and predictive DNA testing by relatives (total sample: n=340 relatives). Secondary outcomes are appreciation of the approach used and impact on familial and psychological functioning, which will be assessed using questionnaires. Relatives who attend genetic counselling will be asked to fill out a questionnaire as well.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the Medical Ethical Committee of the Amsterdam University Medical Centres (MEC 2017-145), the Netherlands. All participants will provide informed consent prior to participation in the study. Results of the study on primary and secondary outcome measures will be published in peer-reviewed journals.

Unaffected siblings of adolescents and adults with fragile X syndrome: Effects on maternal well-being

The present study investigated the effects of children without disabilities on maternal physical and mental health in families with adolescents or adults with fragile X syndrome. Mothers with the FMR1 premutation (N = 87) reported on behavior problems and functional limitations of their adolescent or adult child with fragile X syndrome and their own physical and mental health. Mothers also provided a blood sample to determine FMR1 CGG repeat length. The proportion of unaffected children in the family significantly buffered the effect of both child behavior problems and functional limitations on maternal self-rated health, such that having a higher proportion of unaffected children in the family had a protective effect on maternal health when the target child had more severe behavior problems and functional limitations. There was a similar buffering process for maternal depressive symptoms but at a trend level. Additionally, maternal CGG repeat length had a significant curvilinear association with self-rated health, indicating that mothers with midrange repeat lengths reported the poorest health, whereas mothers with lower and higher repeat lengths in the premutation range reported better health. The data suggest that unaffected children in the family may be an important resource for premutation carrier mothers. Findings are consistent with previous research indicating that mothers with varying levels of genetic liability have variable risk for health problems.

Qualitative Research on Expanded Prenatal and Newborn Screening: Robust but Marginalized

If I told you that screening technologies are iteratively transforming how people experience pregnancy and early parenting, you might take notice. If I mentioned that a new class of newborn patients was being created and that particular forms of parental vigilance were emerging, you might want to know more. If I described how the particular stories told about screening in public, combined with parents' fierce commitment to safeguarding their children's health, make it difficult for problematic experiences with screening to translate into negative opinions about it, you would most likely be intrigued. An extensive qualitative literature documents all these social phenomena, and more, in connection with the spread of prenatal and newborn screening. So why is it, then, that commentators frequently assert that the predicted psychosocial impact of increased screening and testing associated with "the genomic revolution" has been far less severe and worthy of attention than predicted? How can or should social science "evidence" that sits outside adopted measurement conventions be considered? Why is it that summary statements about the psychosocial impact of genomic information often ignore qualitative evidence, or sideline it as relevant only for improving communication among patients, clinicians, and public health systems? This essay addresses such questions, using qualitative research on prenatal and newborn screening as a case study for illustrating the broad methodological, ideological, and dialogical issues at stake.

The Implications of Genetic and Other Biological Explanations for Thinking about Mental Disorders

Given the rise of genetic etiological beliefs regarding psychiatric disorders, a growing body of research has focused on trying to elucidate the effects that such explanatory frameworks might be having on how mental disorders are perceived by patients, clinicians, and the general public. Genetic and other biomedical explanations of mental disorders have long been seen as a potential tool in the efforts to destigmatize mental disorders, given the harshness of the widespread negative attitudes about them and the important negative clinical and social impacts of this stigma. The conventional wisdom has appeared to be that because the effects of genes are seen as falling outside individual control, conceiving of mental disorders as caused by genes casts patients as blameless, thereby reducing stigmatization. Indeed, the results of experimental and correlational research have now robustly linked genetic and other biomedical explanations for mental disorders with reductions in the extent to which people are blamed for their psychiatric symptoms. However, research examining the impact of genetic and other biomedical explanations of mental disorders has also suggested that they can have significant downsides. The most consistently observed negative effect of these kinds of explanations is that they can apparently lead to the assumption that mental disorders are unlikely to improve or abate. Genetic and other biomedical explanations of mental disorders can also increase people's confidence in the effectiveness of biomedical treatments (such as pharmacotherapy) but decrease their confidence in the effectiveness of "nonbiomedical" treatments (such as psychotherapy).

Attitude towards and factors affecting uptake of population-based BRCA testing in the Ashkenazi Jewish population: a cohort study

OBJECTIVE

To evaluate factors affecting unselected population-based BRCA testing in Ashkenazi Jews (AJ).

DESIGN

Cohort-study set within recruitment to the GCaPPS trial (ISRCTN73338115).

SETTING

North London AJ population.

POPULATION OR SAMPLE

Ashkenazi Jews women/men >18 years, recruited through self-referral.

METHODS

Ashkenazi Jews women/men underwent pre-test counselling for BRCA testing through recruitment clinics (clusters). Consenting individuals provided blood samples for BRCA testing. Data were collected on socio-demographic/family history/knowledge/psychological well-being along with benefits/risks/cultural influences (18-item questionnaire measuring 'attitude'). Four-item Likert-scales analysed initial 'interest' and 'intention-to-test' pre-counselling. Uni- and multivariable logistic regression models evaluated factors affecting uptake/interest/intention to undergo BRCA testing. Statistical inference was based on cluster robust standard errors and joint Wald tests for significance. Item-Response Theory and graded-response models modelled responses to 18-item questionnaire.

MAIN OUTCOME MEASURES

Interest, intention, uptake, attitude towards BRCA testing.

RESULTS

A total of 935 individuals (women = 67%/men = 33%; mean age = 53.8 (SD = 15.02) years) underwent pre-test genetic-counselling. During the pre-counselling, 96% expressed interest in and 60% indicated a clear intention to undergo BRCA testing. Subsequently, 88% opted for BRCA testing. BRCA-related knowledge (P = 0.013) and degree-level education (P = 0.01) were positively and negatively (respectively) associated with intention-to-test. Being married/cohabiting had four-fold higher odds for BRCA testing uptake (P = 0.009). Perceived benefits were associated with higher pre-counselling odds for interest in and intention to undergo BRCA testing. Reduced uncertainty/reassurance were the most important factors contributing to decision-making. Increased importance/concern towards risks/limitations (confidentiality/insurance/emotional impact/inability to prevent cancer/marriage ability/ethnic focus/stigmatisation) were significantly associated with lower odds of uptake of BRCA testing, and discriminated between acceptors and decliners. Male gender/degree-level education (P = 0.001) had weaker correlations, whereas having children showed stronger (P = 0.005) associations with attitudes towards BRCA testing.

CONCLUSIONS

BRCA testing in the AJ population has high acceptability. Pre-test counselling increases awareness of disadvantages/limitations of BRCA testing, influencing final cost-benefit perception and decision-making on undergoing testing.

TWEETABLE ABSTRACT

BRCA testing in Ashkenazi Jews has high acceptability and uptake. Pre-test counselling facilitates informed decision-making.

Psychosocial and behavioral outcomes of genomic testing in cancer: a systematic review

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

Fibromyalgia and the concept of resilience

The concept of resilience varies according to the context in which it is used. Resilience is broadly defined as a protective factor that makes people less vulnerable to future adverse life events, in this implying the previous occurrence of an adverse event that has to be confronted before individual equilibrium can be restored. This definition can be applied to fibromyalgia and other chronic pain situations. Resilience is profoundly related to reaction to acute or chronic stress, and is therefore involved in the stress response system. Corticotropin-releasing factor can be considered a fundamental biological element of resilience, which also involves neural mechanisms such as the hypothalamic-pituitary-adrenal (HPA) axis, the locus coeruleus/norepinephrine system, the mesolimbic reward circuit and the fear circuit. Resilience also has a genetic basis: certain genetic characteristics, affect the degree of vulnerability to chronic stress. The number of psychiatric symptoms in healthy adults with high resilience scores do not change when they are exposed to stressing life events, whereas less resilient people develop additional symptoms. This is a typical clinical feature of fibromyalgia. Although resilience could be a therapeutic target for any chronic pain condition, it is an under-developed area of research, particularly in the light of the emerging interactions of positive emotions, physical health, and changes in pro-inflammatory cytokine levels. Given the lack of any pharmacological treatment capable of controlling more than 30-50% of the cases of chronic pain, there is a need to discover new therapeutic targets and strategies capable of changing a non-resilient phenotype into a more resilient phenotype, especially in the case of chronic pain conditions that cannot be explained by a lesion or a disease affecting the somatosensory system. This holds true of fibromyalgia, which is characterised by a complex combination of positive signs and symptoms that vary enormously from person to person depending on a wide range of pathophysiological changes in which genotype and, more importantly, environmental factors may play a major role in developing a more or less resilient personality.

The Role of Palliative Medicine in Assessing Hereditary Cancer Risk

BACKGROUND:

Hereditary cancer assessment and communication about family history risks can be critical for surviving relatives. Palliative care (PC) is often the last set of providers before death.

METHODS:

We replicated a prior study of the prevalence of hereditary cancer risk among patients with cancer receiving PC consultations, assessed the history in the electronic medical record (EMR), and explored patients' attitudes toward discussions about family history. This study was conducted at an academic urban hospital between June 2016 and March 2017.

RESULTS:

The average age of the 75 adult patients with cancer was 60 years, 49 (55%) male and 49 (65%) white. A total of 19 (25%) patients had no clear documentation of family history in the EMR, sometimes because no family history was included in the admission template or an automatically imported template lacked content. In all, 24 (32%) patients had high-risk pedigrees that merited referral to genetic services. And, 48 (64%) patients thought that PC was an appropriate venue to discuss the implications of family history. The mean comfort level in addressing these questions was high.

CONCLUSIONS:

At an academic center, 25% of patients had no family history documented in the EMR. And, 32% of pedigrees warranted referral to genetic services, which was rarely documented. There is substantial room for quality improvement for oncologists and PC specialists-often the last set of providers-to address family cancer risk before death and to increase use and ease of documenting family history in the EMR. Addressing cancer family history could enhance prevention, especially among high-risk families.

Constructions of Decision Making for Risk-Reducing Mastectomy

This research article explores constructions of the decision-making process for risk-reducing mastectomy and considers the consequent role and responsibility of clinical psychologists. Using a Foucauldian discourse analysis approach, three online newspaper articles, five online forums, and four semi-structured interviews were analyzed. Seven discursive constructions are identified and discussed within three broader discourses of mental illness, risk, and embodied selves. Primary conclusions highlight the role for clinical psychologists and health professionals to incorporate the multiple social and political factors involved in discourses that shape decision making. The role of power is critically considered and there is a need for further analysis of "talk" among health professionals.

Reproductive Decision Support: Preferences and Needs of Couples at Risk for Hereditary Cancer and Clinical Geneticists

For couples at high risk of transmitting a cancer predisposition to offspring, reproductive decision-making can be challenging. As the choice between available reproductive options is preference-sensitive, the use of a decision aid can support these couples in their decisional process. The present study aims to investigate preferences and needs of involved stakeholders regarding the development and implementation of a patient decision aid. Semi-structured interviews assessing the needs and preferences regarding the content and functionalities of a decision support program were conducted among seven couples at risk for hereditary cancer and among eight clinical geneticists involved in oncogenetic counseling. Many similarities were found between the expressed preferences and needs of both stakeholder groups concerning the content, barriers and facilitating factors regarding the use of the decision aid, and its implementation. Emphasis was placed on the use of simple non-medical language, an extensive explanation of the procedures and techniques used in prenatal diagnosis (PND) and preimplantation genetic diagnosis (PGD), and the role of health care providers to refer couples to the decision aid. Both stakeholder groups were in favor of incorporating narrative stories in the decision aid. Integrating the present findings with knowledge on reproductive decisional motives and considerations is essential in guiding the development of a decision aid that corresponds to the preferences and needs of end-users.

Family adjustment to diabetes diagnosis in children: Can participation in a study on type 1 diabetes genetic risk be helpful?

BACKGROUND

Diagnosis of type 1 diabetes often causes a negative psychological impact on families. We examined whether parents and children enrolled in The Environmental Determinants of Diabetes in the Young (TEDDY) study differ in their psychological adjustment to diabetes diagnosis compared to children diagnosed with diabetes in the community.

METHODS

TEDDY follows 8676 children at genetic risk for type 1 diabetes from birth. Fifty-four TEDDY children diagnosed with diabetes and 54 age-matched community control children diagnosed with diabetes were enrolled. Participants were aged 3 to 10 years and study visits occurred at 3, 6, and 12 months postdiagnosis. Psychological measures included an adapted diabetes-specific State Anxiety Inventory, the Pediatric Quality of Life Inventory-Diabetes Module, and the Pediatric Inventory for Parents, which measures frequency and difficulty of parenting stress.

RESULTS

A generalized estimating equation analysis based on a difference score between TEDDY children and community controls found no significant differences between TEDDY parents and community controls on parent diabetes-specific anxiety (P = .30). However, TEDDY children exhibited better diabetes-specific quality of life (P = .03) and TEDDY parents reported lower frequency (P = .004) and difficulty (P = .008) of parenting stress compared to community controls.

CONCLUSIONS

Children diagnosed with at-risk for type 1 diabetes who have previously enrolled in research monitoring have improved diabetes quality of life and lower parenting stress postdiagnosis compared to children diagnosed in the community. Families in follow-up studies may be more prepared if their child is diagnosed with diabetes.

The BabySeq project: implementing genomic sequencing in newborns

BACKGROUND

The greatest opportunity for lifelong impact of genomic sequencing is during the newborn period. The "BabySeq Project" is a randomized trial that explores the medical, behavioral, and economic impacts of integrating genomic sequencing into the care of healthy and sick newborns.

METHODS

Families of newborns are enrolled from Boston Children's Hospital and Brigham and Women's Hospital nurseries, and half are randomized to receive genomic sequencing and a report that includes monogenic disease variants, recessive carrier variants for childhood onset or actionable disorders, and pharmacogenomic variants. All families participate in a disclosure session, which includes the return of results for those in the sequencing arm. Outcomes are collected through review of medical records and surveys of parents and health care providers and include the rationale for choice of genes and variants to report; what genomic data adds to the medical management of sick and healthy babies; and the medical, behavioral, and economic impacts of integrating genomic sequencing into the care of healthy and sick newborns.

DISCUSSION

The BabySeq Project will provide empirical data about the risks, benefits and costs of newborn genomic sequencing and will inform policy decisions related to universal genomic screening of newborns.

TRIAL REGISTRATION

The study is registered in ClinicalTrials.gov Identifier: NCT02422511 . Registration date: 10 April 2015.

Our genes, our selves: hereditary breast cancer and biological citizenship in Norway

The concept 'hereditary breast cancer' is commonly used to delineate a group of people genetically at risk for breast cancer-all of whom also having risk for other cancers. People carrying pathogenic variants of the BRCA1 and BRCA2 genes are often referred to as those having predisposition for 'hereditary breast cancer'. The two genes, however, are when altered, associated with different risks for and dying from breast cancer. The main risk for dying for carriers of both genes is from ovarian cancer. These biological facts are of philosophical interest, because they are the facts underlying the public debate on BRCA1/2 genetic testing as a model for the discussion of how to implement genetic knowledge and technologies in personalized medicine. A contribution to this public debate describing inherited breast cancer as 'biological citizenship' recently printed in Med Health Care and Philos illustrated how fragmented and detached from the biological and socio-political facts this debate sometimes is. We here briefly summarize some of the biological facts and how they are implemented in today's healthcare based on agreed philosophical, ethical and moral principles. The suggestion of a 'biological citizenship' defined by hereditary breast cancer is incorrect and ill-advised. 'Identity politics' focusing hereditary breast cancer patients as a group based on a bundle of ill-defined negative arguments is well known, but is supported neither by scientific nor philosophical arguments. To those born with the genetic variants described, the philosophical rule of not doing harm is violated by unbalanced negative arguments.

Evaluating the genetic susceptibility to peer reported bullying behaviors

Bullying is a significant public health concern with lasting impacts on youth. Although environmental risk factors for bullying have been well-characterized, genetic influences on bullying are not well understood. This study explored the role of genetics on early childhood bullying behavior. Participants were 561 children who participated in a longitudinal randomized control trial of a preventive intervention beginning in first grade who were present for the first grade peer nominations used to measure early childhood bullying and who provided genetic data during the age 19-21 year follow-up in the form of blood or saliva. Measures included a polygenic risk score (PRS) derived from a conduct disorder genome wide association study. Latent profile analysis identified three profiles of bullying behaviors during early childhood. Results suggest that the PRS was significantly associated with class membership, with individuals in the moderate bully-victim profile having the highest levels of the PRS and those in the high bully-victim profile having the lowest levels. This line of research has important implications for understanding genetic vulnerability to bullying in early childhood.

Perceived recurrence risk of having another affected child: A survey on parents of children with autism spectrum disorders in Taiwan

OBJECTIVE

Autism Spectrum Disorders (ASD) have a significant genetic predisposition. The recurrence risk of ASD ranges from 3% to 18.7% for parents having one affected child. As recurrence risk perceptions have important implications for family planning, prenatal preparation, and future children managements, absolute and relative recurrence risk perceptions of having another affected child among Taiwanese parents of children with ASD were assessed.

METHODS

This study collected quantitative survey data from 415 Taiwanese parents who had one child with ASD.

RESULTS

Participants reported their absolute recurrence risk of having another child with ASD was 33.4%. Compared to other parents with normally-developing children, merely 49.8% of participants perceived higher relative recurrence risk. By controlling for the sociodemographic characteristics, participants' absolute recurrence risk perceptions were significantly predicted by their perceived genetic causes of ASD and family history of ASD. Yet, participants' relative recurrence risk perceptions were significantly associated with only the perceived genetic etiology.

CONCLUSION

Taiwanese parents of children diagnosed with ASD had an incorrect understanding of their absolute and relative recurrence risks.

PRACTICE IMPLICATIONS

To facilitate informed decision-making in family planning, healthcare providers should discuss absolute and relative recurrence risks as well as genetic causes of ASD with this particular group.

Mental Models of Cause and Inheritance for Type 2 Diabetes Among Unaffected Individuals Who Have a Positive Family History

Using the familial risk perception (FRP) model as a framework, we elicited causal and inheritance explanations for type 2 diabetes (T2D) from people who do not have T2D but have a family history for it. We identified four composite mental models for cause of T2D: (a) purely genetic; (b) purely behavioral/environmental; (c) direct multifactorial, in which risk factors interact and over time directly lead to T2D; and (d) indirect multifactorial, in which risk factors interact and over time cause a precursor health condition (such as obesity or metabolic syndrome) that leads to T2D. Interestingly, participants described specific risk factors such as genetics, food habits, lifestyle, weight, and culture as "running in the family." Our findings provide insight into lay beliefs about T2D that can be used by clinicians to anticipate or make sense of responses to questions they pose to patients about mental models for T2D.

Previvors' Uncertainty Management Strategies for Hereditary Breast and Ovarian Cancer

Individuals with a genetic predisposition to develop hereditary breast and ovarian cancer (HBOC), but who have not been diagnosed with cancer, are referred to as previvors. Although genetic testing may reduce previvors' worries about whether or not they have a high genetic cancer risk, testing positive produces negative emotions and long-term uncertainty-thus requiring the management of uncertainty. Existing research indicates family, friends, and social support networks are limited in their assistance for previvors' uncertainty management. Therefore, this study examined how health care providers may assist previvors in uncertainty management by asking: What strategies do BRCA-positive previvors enact with their health care providers to help manage their uncertainty about HBOC? Purposive sampling was employed to recruit participants via online social media. The final sample consisted of 34 BRCA-positive women. Interviews revealed four uncertainty management strategies-seeking health care providers as informational sources, seeking health care providers as partners for decision making, seeking health care providers for supportive communication, and seeking referrals from health care providers for social support networks. Findings indicate that health care providers who are knowledgeable about BRCA, provide information, answer questions, check understanding, and provide additional resources assist previvors in managing their uncertainties by distinguishing options and fostering meaning.

Feasibility study to assess the impact of a lifestyle intervention ('LivingWELL') in people having an assessment of their family history of colorectal or breast cancer

OBJECTIVES

To assess the feasibility of delivering and evaluating a weight management (WM) programme for overweight patients with a family history (FH) of breast cancer (BC) or colorectal cancer (CRC).

STUDY DESIGN

A two-arm (intervention vs usual care) randomised controlled trial.

SETTING

National Health Service (NHS) Tayside and NHS Grampian.

PARTICIPANTS

People with a FH of BC or CRC aged≥18 years and body mass index of ≥25 kg/m² referred to NHS genetic services.

INTERVENTION

Participants were randomised to a control (lifestyle booklet) or 12-week intervention arm where they were given one face-to-face counselling session, four telephone consultations and web-based support. A goal of 5% reduction in body weight was set, and a personalised diet and physical activity (PA) programme was provided. Behavioural change techniques (motivational interviewing, action and coping plans and implementation intentions) were used.

PRIMARY OUTCOME

Feasibility measures: recruitment, programme implementation, fidelity measures, achieved measurements and retention, participant satisfaction assessed by questionnaire and qualitative interviews.

SECONDARY OUTCOMES

Measured changes in weight and PA and reported diet and psychosocial measures between baseline and 12-week follow-up.

RESULTS

Of 480 patients approached, 196 (41%) expressed interest in the study, and of those, 78 (40%) patients were randomised. Implementation of the programme was challenging within the time allotted and fidelity to the intervention modest (62%). Qualitative findings indicated the programme was well received. Questionnaires and anthropometric data were completed by >98%. Accelerometer data were attained by 84% and 54% at baseline and follow-up, respectively. Retention at 12 weeks was 76%. Overall, 36% of the intervention group (vs 0% in control) achieved 5% weight loss. Favourable increases in PA and reduction in dietary fat were also reported.

CONCLUSIONS

A lifestyle programme for people with a family history of cancer is feasible to conduct and acceptable to participants, and indicative results suggest favourable outcomes.

"Take your time, then follow your heart:" Previvors' advice for communicating about family planning after testing positive for a BRCA genetic variant

INTRODUCTION

The purpose of this study was to identify previvors' strategies for communicating about family planning after testing positive for a variant of the "breast cancer gene" (BRCA).

METHOD

Semistructured interviews were conducted with 20 women currently in committed romantic relationships, but who had not yet completed family planning upon finding out about their BRCA mutation status.

RESULTS

Data analysis produced three categories of participant advice given to newly diagnosed previvors. Participants advised the following: (a) the importance of engaging in two-way dialogue with their partners/spouses across the life span of the partnership, (b) seeking information on new technologies and information regarding family-planning and genetic-cancer-prevention decision-making, as well as recognizing where to go for different support needs, and (c) managing and acknowledging emotions surrounding their BRCA-related health decisions.

DISCUSSION

Previvors who have already had family-planning and genetic-cancer-risk conversations had important advice for newly diagnosed previvors. Practical advice for starting and managing conversations with partners/spouses, family members, and friends are discussed. (PsycINFO Database Record

"My Plate is Full": Reasons for Declining a Genetic Evaluation of Hearing Loss

The aim of this study was to obtain patient and parent perspectives on genetic evaluation of hearing loss, in order to identify motivators, expectations, and barriers. Three focus groups were conducted following a semi-structured discussion guide, led by an independent moderator. Participants were hearing parents of children with permanent hearing loss or deaf adults. Qualitative content analysis was used to develop a codebook and identify major themes and subthemes. Participant views were compared to national guidelines. The 28 participants comprised 23 parents representing 21 unique families and 5 deaf adults. 13/21 families and 0/5 adults reported comorbidities, 4/21 families and 3/5 adults had a positive family history, and 12/21 families versus 0/5 adults had utilized genetics services. A common theme among adults and parents was a curiosity as to the cause of hearing loss. Parents were motivated to detect comorbidities and optimize care for hearing loss. Some parents felt overwhelmed by the hearing loss and unprepared to pursue early genetic evaluation as recommended in guidelines. Several reported positive experiences following genetics consultation, while others reported unease and unmet expectations. Notably, both parents and adults expressed ambivalence regarding the desire for genetic knowledge. Financial concerns and difficulties obtaining a referral were cited as extrinsic barriers. For parents of children with hearing loss, both the presence of comorbidities and a positive family history were drivers of genetics consultation and/or genetic testing. We identified educational opportunities for both patients and providers that would improve informed decision-making and increase access to genetic services. Consideration of the patient/family perspective and their decision-making processes, along with flexibility in the approach to genetics evaluation and its timing, will optimize both the development and implementation of guidelines.

"When information is not enough": A model for understanding BRCA-positive previvors' information needs regarding hereditary breast and ovarian cancer risk

OBJECTIVE

To investigate BRCA-positive, unaffected patients' - referred to as previvors - information needs after testing positive for a deleterious BRCA genetic mutation.

METHODS

25 qualitative interviews were conducted with previvors. Data were analyzed using the constant comparison method of grounded theory.

RESULTS

Analysis revealed a theoretical model of previvors' information needs related to the stage of their health journey. Specifically, a four-stage model was developed based on the data: (1) pre-testing information needs, (2) post-testing information needs, (3) pre-management information needs, and (4) post-management information needs. Two recurring dimensions of desired knowledge also emerged within the stages-personal/social knowledge and medical knowledge.

CONCLUSIONS

While previvors may be genetically predisposed to develop cancer, they have not been diagnosed with cancer, and therefore have different information needs than cancer patients and cancer survivors.

PRACTICE IMPLICATIONS

This model can serve as a framework for assisting healthcare providers in meeting the specific information needs of cancer previvors.

A GABRA2 polymorphism improves a model for prediction of drinking initiation

BACKGROUND

Survival analysis was used to explore the addition of a single nucleotide polymorphism (SNP) and covariates (sex, interview age, and ancestry) on a previously published model's ability to predict onset of drinking. A SNP variant of rs279871, in the chromosome 4 gene encoding gamma-aminobutyric acid receptor (GABRA2), was selected due to its associations with alcoholism in young adults and with behaviors that increased risk for early drinking.

METHODS

A subsample of 674 adolescents (ages 14-17) participating in the Collaborative Study on the Genetics of Alcoholism (COGA) was examined using a previously derived Cox proportional hazards model containing: 1) number of non-drinking related conduct disorder (CD) symptoms, 2) membership in a high-risk alcohol-dependent (AD) family, 3) most best friends drank (MBFD), 4) Achenbach Youth Self Report (YSR) externalizing score, and 5) YSR social problems score. The above covariates along with the SNP variant of GABRA2, rs279871, were added to this model. Five new prototype models were examined. The most parsimonious model was chosen based on likelihood ratio tests and model fit statistics.

RESULTS

The final model contained four of the five original predictors (YSR social problems score was no longer significant and hence dropped from subsequent models), the three covariates, and a recessive GABRA2 rs279871 TT genotype (two copies of the high-risk allele containing thymine). The model indicated that adolescents with the high-risk TT genotype were more likely to begin drinking than those without this genotype.

CONCLUSIONS

The joint effect of the gene (rs279871 TT genotype) and environment (MBFD) on adolescent alcohol initiation is additive, but not interactive, after controlling for behavior problems (CD and YSR externalizing score). This suggests that the impact of the high-risk TT genotype on the onset of drinking is affected by controlling for peer drinking and does not include genotype-by-environment interactions.

Blue Genes? Understanding and Mitigating Negative Consequences of Personalized Information about Genetic Risk for Depression

Personalized genetic testing for vulnerability to mental disorders is expected to become increasingly common. It is therefore important to understand whether learning about one's genetic risk for a mental disorder has negative clinical implications, and if so, how these might be counteracted. Among participants with depressive symptoms, we administered a sham biochemical test purportedly revealing participants' level of genetic risk for major depression. Participants told that they carried a genetic predisposition to depression expressed significantly lower confidence in their ability to cope with depressive symptoms than participants told they did not carry this predisposition. A short intervention providing education about the non-deterministic nature of genes' effects on depression fully mitigated this negative effect, however. Given the clinical importance of patient expectancies in depression, the notion that pessimism about one's ability to overcome symptoms could be exacerbated by genetic information-which will likely become ever more widely available-represents cause for concern. Education and counseling about the malleability of genetic effects may be an important tool for counteracting clinically deleterious beliefs that can be evoked by genetic test results. Genetic counselors may be able to help patients avoid becoming demoralized by learning they have a genetic predisposition to depression by providing education about the non-deterministic role of biology in depression, and a brief audiovisual intervention appears to be an effective approach to delivering such education.
