The perceived personal control (PPC) questionnaire as an outcome of genetic counseling: reliability and validity of the instrument

Patient perspective in perceived comparative genetic mutation risk: An exploratory review

The genetic risk of chronic diseases represents a complex medical setting in which individuals need to adapt to health conditions that manage daily living towards to healthy behaviours. This exploratory review focused on psychological counselling for genetic risk diagnosis. This study aimed to address the psychological management of the impact of genetic risk on chronic diseases. We performed a systematic search of MEDLINE via PubMed, Embase, Web of Science, PsycINFO and Scopus for articles from May 2012 to August 2023. A descriptive analysis of the characteristics of the included studies was conducted. Based on the exclusion/inclusion criteria, the literature search yielded 250 studies. Seventeen full texts were assessed for eligibility and 207 articles were excluded. Observational (n = 15) and randomised clinical trials (n = 2) were examined. Most studies have been conducted on oncological diagnoses; the emotional dimensions examined have been worry, depression, anxiety and stress in most diseases. Psychological measures are based on self-reports and questionnaires; few studies have investigated the connections between quality of life, psychological traits and emotional dimensions. The complexity of clinics and from daily diagnostic and treatment practices to the everyday experience of those living with the risk of disease might be addressed in counselling settings to improve quality of life in genetic risk, increasing mental adaptation to tailored chronic conditions. Thus, the empowerment of communication of genetic risk information should be part of the general trend towards personalised medicine.

A randomized clinical trial of genetic testing and personalized risk counselling in patients with type 2 diabetes receiving integrated care -The genetic testing and patient empowerment (GEM) trial

AIMS

We evaluated the effect of personalized risk counseling incorporating clinical and genetic risk factors on patient empowerment and risk factor control in diabetes.

METHODS

Patients with type 2 diabetes (T2D) with suboptimal glycaemic control (HbA1c ≥ 7.5%) were randomized to a genetic counselling (GC) or control group. All patients underwent genetic testing for alleles at three loci associated with diabetic complications. The GC group received additional explanation of the joint associations of genetic and modifiable risk factors on risk of complications. All patients were reassessed at 12 months including validated questionnaires for patient reported outcomes. The primary outcome was proportion of patients reaching ≥ 3 of 5 predefined treatment targets (HbA1c < 7%, BP < 130/80 mmHg, LDL-C < 2.6 mmol/L, Triglyceride < 2.0 mmol/L, use of renin-angiotensin system inhibitors). Secondary outcomes included new-onset chronic kidney disease or microalbuminuria and patient reported outcome measures.

RESULTS

A total of 435 patients were randomized and 420 patients were included in the modified intention-to-treat analysis. At 12 months, the proportion of patients who attained ≥ 3 targets increased from 41.6% to 52.3% in the GC group (p = 0.007) versus 49.5% to 62.6% in the control group (p = 0.003), without between-group difference. Both groups had similar reduction in HbA1c, LDL-C and increased use of medications. In per protocol analysis, the GC group had higher diabetes empowerment, with reduced diabetes distress. In the GC group, the greatest improvement in positive attitude and self-care activities was observed in the intermediate to high genetic risk score (GRS) groups.

CONCLUSIONS

In patients with T2D receiving integrated care, additional counselling on genetic risk of complications did not further improve risk factor control, although the improvement in self-efficacy warrants long-term evaluation.

A randomized experimental study to test the effects of discussing uncertainty during cancer genetic counseling: different strategies, different outcomes?

Uncertainty is increasingly discussed during genetic counseling due to innovative techniques, e.g., multigene panel testing. Discussions about uncertainty may impact counselees variably, depending on counselors' communication styles. Ideally, the discussion of uncertainty enables counselees to cope with uncertainty and make well-informed decisions about testing. We examined the impact of how counselors convey uncertainty and address counselees' uncertainty, and explored the role of individual characteristics. Therefore, a randomized controlled experiment using videos was conducted. Former counselees (N = 224) viewed one video depicting a genetic consultation about multigene panel testing. The extent of counselors' communication of uncertainty (comprehensive vs. the essence) and their response to counselees' uncertainty expressions (providing information vs. providing space for emotions vs. normalizing and counterbalancing uncertainty) were systematically manipulated. Individual characteristics, e.g., uncertainty tolerance, were assessed, as well as outcome variables (primary outcomes: feelings of uncertainty and information recall). No effects were found on primary outcomes. Participants were most satisfied when the essence was communicated, combined with providing information or providing space responses (p = 0.002). Comprehensive information resulted in less perceived steering toward testing (p = 0.005). Participants with lower uncertainty tolerance or higher trait anxiety were less confident about their understanding when receiving comprehensive information (p = 0.025). Participants seeking information experienced less uncertainty (p = 0.003), and trusted their counselor more (p = 0.028), when the counselor used information providing responses. In sum, the impact of discussing uncertainty primarily depends on individual characteristics. Practical guidelines should address how to tailor the discussion of uncertainty.

Cognitive and affective outcomes of genetic counselling in the Netherlands at group and individual level: a personalized approach seems necessary

We performed a large outcome study at group and individual level in which the goals of genetic counselling were operationalized into cognitive and affective outcomes: empowerment, perceived personal control and anxiety. We then examined which socio-demographic and clinical variables were associated with changes in these outcomes. Data came from 1479 counselees who completed questionnaires (GCOS-18, PPC and STAI) at three time points: before the start of genetic counselling, after the first consultation and after the results of genetic counselling were disclosed. Results showed that at group level empowerment, perceived personal control and anxiety improved significantly after the whole genetic counselling process. Effect-sizes were medium for empowerment and small for the other outcomes. At individual level, 48% of counselees improved in empowerment, 21% in perceived personal control and 17% in anxiety. Around 10% of counselees worsened on all outcomes. Only ‘reason for referral’ and ‘genetic test result’ were significantly associated with changes in outcomes. This study demonstrated improvements among counselees in cognitive and affective outcomes after genetic counselling at group level. However, our results also suggest that there are opportunities for improvement at individual level, as many counselees remained stable and some even worsened on all outcomes. Routine outcome monitoring could help to explore the needs of counselees and could help to identify counselees who worsen.

A validated PROM in genetic counselling: the psychometric properties of the Dutch version of the Genetic Counselling Outcome Scale

Patient empowerment has been identified as a key outcome goal in genetic counselling, and a patient reported outcome measure (PROM) has been developed to measure empowerment in genetic services: the Genetic Counselling Outcome Scale (GCOS). Here we validate the GCOS for a large and diverse Dutch study sample of 2194 patients referred to two clinical genetic centres for counselling about a wide range of conditions (heart disease, neurological disorders, cancer, congenital syndromes, intellectual disability and prenatal pathology). Our results suggest that the GCOS consists of a hierarchical 6-factor structure, with a main scale for empowerment and six subscales: uncertainty about heredity, hope, negative emotions, knowledge about the condition, knowledge about genetic services and uncertainty about the treatment. Six of the original 24 GCOS items were removed due to low factor loadings and small inter-item correlations. Internal consistency and test-retest reliability of the main scale and most subscales were satisfactory. Convergent validity was confirmed by moderate positive and moderate/strong negative associations between the GCOS main scale and other validated outcome measures. Responsiveness was comparable to that of other validated outcome measures. We saw significant improvement in the GCOS main scale and all the subscales after the first genetic counselling session. This study contributes to the international validation process of the GCOS, with the ultimate goal of using this instrument as a PROM, with empowerment as an outcome measure, to evaluate and improve the quality of genetic counselling in various clinical genetics settings.

Genetic Testing in a Population-Based Sample of Breast and Ovarian Cancer Survivors from the REACH Randomized Trial: Cost Barriers and Moderators of Counseling Mode

Background: This study evaluates predictors of BRCA1/2 testing among breast and ovarian cancer survivors who received genetic counseling as part of a randomized trial and evaluates moderators of counseling mode on testing uptake.Methods: Predictors of BRCA1/2 testing within one year postcounseling were evaluated using multivariable logistic regression in a population-based sample of breast and ovarian cancer survivors at increased hereditary risk randomly assigned to in-person counseling (IPC; n = 379) versus telephone counseling (TC; n = 402). Variables that moderated the association between counseling mode and testing were identified by subgroup analysis.Results: Testing uptake was associated with higher perceived comparative mutation risk [OR = 1.32; 95% confidence interval (CI), 1.11-1.57] in the adjusted analysis. Those without cost barriers had higher testing uptake (OR = 18.73; 95% CI, 7.09-49.46). Psychologic distress and perceived comparative mutation risk moderated the effect of counseling and testing. Uptake between IPC versus TC did not differ at low levels of distress and risk, but differed at high distress (26.3% TC vs. 44.3% IPC) and high perceived comparative risk (33.9% TC vs. 50.5% IPC).Conclusions: Cost concerns are a strong determinant of testing. Differences in testing uptake by counseling mode may depend on precounseling distress and risk perceptions.Impact: Cost concerns may contribute to low testing in population-based samples of at-risk cancer survivors. Precounseling psychosocial characteristics should be considered when offering in-person versus telephone counseling. Cancer Epidemiol Biomarkers Prev; 26(12); 1772-80. ©2017 AACR.

Follow-up care by a genetic counsellor for relatives at risk for cardiomyopathies is cost-saving and well-appreciated: a randomised comparison

Increasing numbers of patient relatives at risk of developing dilated or hypertrophic cardiomyopathy (DCM/HCM) are being identified and followed up by cardiologists according to the ACC/ESC guidelines. However, given limited healthcare resources, good-quality low-cost alternative approaches are needed. Therefore, we have compared conventional follow-up by a cardiologist with that provided at a cardiogenetic clinic (CGC) led by a genetic counsellor. Phenotype-negative first-degree relatives at risk for DCM/HCM were randomly assigned to see either a cardiologist or to attend a CGC. Uptake and resource use were recorded. For 189 participants, we evaluated quality of care experienced, patient satisfaction and perceived personal control (PPC) using validated questionnaires and estimated the average cost difference of these two modes of care. Maximum patient satisfaction scores were achieved more frequently at the CGC (86% vs 45%, P<0.01). In terms of follow-up care provided, the genetic counsellor did not perform worse than the cardiologist (95% vs 59%, P<0.01). The genetic counsellor more often enquired about the relative-at risk's health (100% vs 65%, P<0.01) and family health (97% vs 33%, P<0.01), measured blood pressure (98% vs 29%, P<0.01) and gave disease-specific information (77% vs 52%, P<0.01). Although PPC scores were equal in both groups, the average cost per patient of CGC follow-up was 25% lower. Follow-up of phenotype-negative relatives at risk for DCM/HCM at a CGC led to greater patient satisfaction and is well-appreciated at lower cost. CGC care is a good alternative to conventional cardiological follow-up for this growing group of patients.

Psychological factors associated with the intention to choose for risk-reducing mastectomy in family cancer clinic attendees

OBJECTIVES

Women seeking counseling because of familial breast cancer occurrence face difficult decisions, such as whether and when to opt for risk-reducing mastectomy (RRM) in case of BRCA1/2 mutation. Only limited research has been done to identify the psychological factors associated with the decision for RRM. This study investigated which psychological factors are related to the intention to choose for RRM.

MATERIALS & METHODS

A cohort of 486 cancer-unaffected women with a family history of breast cancer completed the following questionnaires prior to genetic counseling: the Cancer Worry Scale, Positive And Negative Affect Scale, Perceived Personal Control Scale, Hospital Anxiety and Depression Scale and State Anxiety Scale and questions regarding socio-demographic characteristics, family history, risk perception and RRM intention. Multivariate logistic regression was used to analyze the relation between psychological factors and women's intention to choose for RRM.

RESULTS

Factors associated with RRM intention were high positive affect (OR = 1.86, 95%CI = 1.12-3.08), high negative affect (OR = 2.52, 95%CI = 1.44-4.43), high cancer worry (OR = 1.65, 95%CI = 1.00-2.72), high perceived personal control (OR = 3.58, 95%CI = 2.18-5.89), high risk-perception (OR = 1.85, 95%CI = 1.15-2.95) and having children (OR = 2.06, 95%CI = 1.21-3.50).

CONCLUSION

Negative and positive affects play an important role in the intention for RRM. Furthermore, perceived personal control over the situation is associated with an intention for RRM. In addition to focusing on accurate risk communication, counseling should pay attention to the influence of perceived control and emotions to facilitate decision-making.

Randomized Noninferiority Trial of Telephone Delivery of BRCA1/2 Genetic Counseling Compared With In-Person Counseling: 1-Year Follow-Up

PURPOSE

The ongoing integration of cancer genomic testing into routine clinical care has led to increased demand for cancer genetic services. To meet this demand, there is an urgent need to enhance the accessibility and reach of such services, while ensuring comparable care delivery outcomes. This randomized trial compared 1-year outcomes for telephone genetic counseling with in-person counseling among women at risk of hereditary breast and/or ovarian cancer living in geographically diverse areas.

PATIENTS AND METHODS

Using population-based sampling, women at increased risk of hereditary breast and/or ovarian cancer were randomly assigned to in-person (n = 495) or telephone genetic counseling (n = 493). One-sided 97.5% CIs were used to estimate the noninferiority effects of telephone counseling on 1-year psychosocial, decision-making, and quality-of-life outcomes. Differences in test-uptake proportions for determining equivalency of a 10% prespecified margin were evaluated by 95% CIs.

RESULTS

At the 1-year follow-up, telephone counseling was noninferior to in-person counseling for all psychosocial and informed decision-making outcomes: anxiety (difference [d], 0.08; upper bound 97.5% CI, 0.45), cancer-specific distress (d, 0.66; upper bound 97.5% CI, 2.28), perceived personal control (d, -0.01; lower bound 97.5% CI, -0.06), and decisional conflict (d, -0.12; upper bound 97.5% CI, 2.03). Test uptake was lower for telephone counseling (27.9%) than in-person counseling (37.3%), with the difference of 9.4% (95% CI, 2.2% to 16.8%). Uptake was appreciably higher for rural compared with urban dwellers in both counseling arms.

CONCLUSION

Although telephone counseling led to lower testing uptake, our findings suggest that telephone counseling can be effectively used to increase reach and access without long-term adverse psychosocial consequences. Further work is needed to determine long-term adherence to risk management guidelines and effective strategies to boost utilization of primary and secondary preventive strategies.

Prognostic Factors for Distress After Genetic Testing for Hereditary Cancer

The psychological impact of an unfavorable genetic test result for counselees at risk for hereditary cancer seems to be limited: only 10-20 % of counselees have psychological problems after testing positive for a known familial mutation. The objective of this study was to find prognostic factors that can predict which counselees are most likely to develop psychological problems after presymptomatic genetic testing. Counselees with a 50 % risk of BRCA1/2 or Lynch syndrome completed questionnaires at three time-points: after receiving a written invitation for a genetic counseling intake (T1), 2-3 days after receiving their DNA test result (T2), and 4-6 weeks later (T3). The psychological impact of the genetic test result was examined shortly and 4-6 weeks after learning their test result. Subsequently, the influence of various potentially prognostic factors on psychological impact were examined in the whole group. Data from 165 counselees were analyzed. Counselees with an unfavorable outcome did not have more emotional distress, but showed significantly more cancer worries 4-6 weeks after learning their test result. Prognostic factors for cancer worries after genetic testing were pre-existing cancer worries, being single, a high risk perception of getting cancer, and an unfavorable test result. Emotional distress was best predicted by pre-existing cancer worries and pre-existing emotional distress. The psychological impact of an unfavorable genetic test result appears considerable if it is measured as "worries about cancer." Genetic counselors should provide additional guidance to counselees with many cancer worries, emotional distress, a high risk perception or a weak social network.

Telegenetics use in presymptomatic genetic counselling: patient evaluations on satisfaction and quality of care

In recent years, online counselling has been introduced in clinical genetics to increase patients' access to care and to reduce time and cost for both patients and professionals. Most telegenetics reports so far evaluated online oncogenetic counselling at remote health centres in regions with large travelling distances, generally showing positive patient outcomes. We think online counselling--including the use of supportive tools that are also available during in-person counseling--of presymptomatic patients in their homes can also be feasible and valuable for patients in relatively small regions. We performed a single-centre pilot study of online genetic counselling for 57 patients who were presymptomatic cardiogenetic (n=17), presymptomatic oncogenetic (n=34) and prenatal (3 couples). One-third of presymptomatic patients we approached consented to online counselling. Patient evaluations of practical aspects, satisfaction and psychological outcomes were assessed and compared with a matched control group. Patients managed to fulfil the preparations, were significantly more satisfied with their counsellor and counselling session than controls and were satisfied with the online counselling more than they expected to be beforehand. Psychological outcomes (decreased anxiety and increased control) did not differ with control patients. Technical problems occurred in almost half of online sessions. Nonetheless, online counselling in patients' homes proved to be feasible and was appreciated by a substantial part of presymptomatic patients at our genetics centre in the Netherlands. Based on these outcomes, we conclude online counselling can be a valuable addition to existing counselling options in regular patient care.

Disclosing genetic risk for coronary heart disease: effects on perceived personal control and genetic counseling satisfaction

We investigated whether disclosure of coronary heart disease (CHD) genetic risk influences perceived personal control (PPC) and genetic counseling satisfaction (GCS). Participants (n = 207, age: 45-65 years) were randomized to receive estimated 10-year risk of CHD based on a conventional risk score (CRS) with or without a genetic risk score (GRS). Risk estimates were disclosed by a genetic counselor who also reviewed how GRS altered risk in those randomized to CRS+GRS. Each participant subsequently met with a physician and then completed surveys to assess PPC and GCS. Participants who received CRS+GRS had higher PPC than those who received CRS alone although the absolute difference was small (25.2 ± 2.7 vs 24.1 ± 3.8, p = 0.04). A greater proportion of CRS+GRS participants had higher GCS scores (17.3 ± 5.3 vs 15.9 ± 6.3, p = 0.06). In the CRS+GRS group, PPC and GCS scores were not correlated with GRS. Within both groups, PPC and GCS scores were similar in patients with or without family history (p = NS). In conclusion, patients who received their genetic risk of CHD had higher PPC and tended to have higher GCS. Our findings suggest that disclosure of genetic risk of CHD together with conventional risk estimates is appreciated by patients. Whether this results in improved outcomes needs additional investigation.

A group approach to genetic counselling of cardiomyopathy patients: satisfaction and psychological outcomes sufficient for further implementation

The introduction of next-generation sequencing in everyday clinical genetics practise is increasing the number of genetic disorders that can be confirmed at DNA-level, and consequently increases the possibilities for cascade screening. This leads to a greater need for genetic counselling, whereas the number of professionals available to provide this is limited. We therefore piloted group genetic counselling for symptomatic cardiomyopathy patients at regional hospitals, to assess whether this could be an acceptable alternative to individual counselling. We performed a cohort study with pre- and post-counselling patient measurements using questionnaires, supplemented with evaluations of the group counselling format by the professionals involved. Patients from eight regional hospitals in the northern part of the Netherlands were included. Questionnaires comprised patient characteristics, psychological measures (personal perceived control (PPC), state and trait anxiety inventory (STAI)), and satisfaction with counsellors, counselling content and design. In total, 82 patients (mean age 57.5 year) attended one of 13 group sessions. Median PPC and STAI scores showed significantly higher control and lower anxiety after the counselling. Patients reported they were satisfied with the counsellors, and almost 75% of patients were satisfied with the group counselling. Regional professionals were also, overall, satisfied with the group sessions. The genetics professionals were less satisfied, mainly because of their perceived large time investment and less-than-expected group interaction. Hence, a group approach to cardiogenetic counselling is feasible, accessible, and psychologically effective, and could be one possible approach to counselling the increasing patient numbers in cardiogenetics.

Follow-up effects of a tailored pre-counseling website with question prompt in breast cancer genetic counseling

OBJECTIVE

Pre-counseling education helps counselees to prepare for breast cancer genetic counseling and might subsequently result in more positive experiences, improved cognitive outcomes and more experienced control. This study assessed the effects of a website with tailored information and a blank sheet to fill in questions (question prompt; QP), at 1 week and 1 year post-counseling.

METHODS

Consecutive counselees were randomized to the usual care group (UC) or the intervention group (UC+website+QP). Counselees completed questionnaires pre- and post-counseling and 1 year follow-up. We conducted multilevel regression analyses corrected for time.

RESULTS

Intervention group counselees (n = 103) were more satisfied about their final visit (β = .35; CI: .06-.65; P = .02; n = 156) than UC group counselees (n = 94). Intervention group counselees also reported more positive experiences with the counseling (β = .32; CI: .06-.59; P = .02; n = 188) and higher perceived personal control 1 year post-counseling (β = .51; CI: .18-.84; P = .002; n = 193). No significant effects were found on recall, knowledge, anxiety, cancer worry, risk perception alignment and adherence to breast surveillance advice.

CONCLUSION

This study shows that pre-counseling education providing tailored information and QP, might lead to improvements in experiences with the counseling and perceived personal control 1 year post-counseling.

PRACTICE IMPLICATIONS

Online pre-visit information is a feasible tool to enhance counselees' experiences.

Analyzing communication in genetic consultations--a systematic review

OBJECTIVE

To systematically review studies that have analyzed communication within medical consultations involving genetic specialists and report on their findings and design.

METHODS

Drawing from PRISMA and appropriate guidelines for reviewing qualitative research, a systematic search of seven databases was conducted, followed by selection of studies for inclusion based on a set of criteria. Three authors conducted data extraction and narrative synthesis.

RESULTS

Twenty-two studies were identified and were heterogeneous in setting, design, and methods, with many including limited descriptions of health professionals involved. Despite this variability, studies generally pursued the following three main objectives: searching for structural patterns within consultations, investigating communication and genetic counseling concepts, and linking process with input- and outcome-measures. Structural patterns identified included clinician dialog dominating consultations, and talk being mostly biomedical. Counseling and communication concepts investigated were: risk communication, the negotiation of power and knowledge, and adherence to genetic counseling ideals. Attempts to link consultation data to input- or outcome-measures were often unsuccessful.

CONCLUSION

More interdisciplinary research, grounded in appropriate theoretical frameworks, is needed to explore inherent complexities in this setting.

PRACTICE IMPLICATIONS

Findings from this review can be used to guide the design of future research into the process of genetic consultations.

Counselee participation in follow-up breast cancer genetic counselling visits and associations with achievement of the preferred role, cognitive outcomes, risk perception alignment and perceived personal control

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

Medical management adherence as an outcome of genetic counseling in a pediatric setting

PURPOSE

We sought to determine whether the inclusion of a genetic counselor in an initial pediatric genetics visit had an impact on patient adherence to management recommendations, as compared with initial visits in which only genetics physicians were involved.

METHODS

This chart review included 198 pediatric patients seen for their initial visit to the general genetics clinic at the Cincinnati Children's Hospital Medical Center in 2008. Ninety-eight patients were seen by one or more genetics physicians (the non-genetic counselor group), and 100 patients were seen by a geneticist and a genetic counselor (the genetic counselor group). Medical management recommendations and evidence of adherence to recommendations were abstracted from the medical record; adherence rates were compared between the genetic counselor and non-genetic counselor groups.

RESULTS

Adherence was significantly associated with the inclusion of a genetic counselor (P = 0.009). Although type of management recommendation had a large impact on adherence, involvement of a genetic counselor significantly improved adherence in all three management recommendation categories.

CONCLUSION

Involvement of a genetic counselor during an initial pediatric genetics visit may be associated with increased patient adherence. Further research is needed to determine whether this association applies in other genetic counseling settings and whether enhanced adherence results in improved medical outcomes.

The effectiveness of a graphical presentation in addition to a frequency format in the context of familial breast cancer risk communication: a multicenter controlled trial

Background

Inadequate understanding of risk among counselees is a common problem in familial cancer clinics. It has been suggested that graphical displays can help counselees understand cancer risks and subsequent decision-making. We evaluated the effects of a graphical presentation in addition to a frequency format on counselees’ understanding, psychological well-being, and preventive intentions.

Design: Multicenter controlled trial.

Setting: Three familial cancer clinics in the Netherlands.

Methods

Participants: Unaffected women with a breast cancer family history (first-time attendees).

Intervention: Immediately after standard genetic counseling, an additional consultation by a trained risk counselor took place where women were presented with their lifetime breast cancer risk in frequency format (X out of 100) (n = 63) or frequency format plus graphical display (10 × 10 human icons) (n = 91).

Main outcome measures: understanding of risk (risk accuracy, risk perception), psychological well-being, and intentions regarding cancer prevention. Measurements were assessed using questionnaires at baseline, 2-week and 6-month follow-up.

Results

Baseline participant characteristics did not differ between the two groups. In both groups there was an increase in women’s risk accuracy from baseline to follow-up. No significant differences were found between women who received the frequency format and those who received an additional graphical display in terms of understanding, psychological well-being and intentions regarding cancer prevention. The groups did not differ in their evaluation of the process of counseling.

Conclusion

Women’s personal risk estimation accuracy was generally high at baseline and the results suggest that an additional graphical display does not lead to a significant benefit in terms of increasing understanding of risk, psychological well-being and preventive intentions.

Short-term psychological impact of the BRCA1/2 test result in women with breast cancer according to their perceived probability of genetic predisposition to cancer

Background:

The effect of BRCA1/2 gene test result on anxiety, depression, cancer-related thought intrusion or avoidance and perceived control over cancer risk was assessed in breast cancer (BC) patients, according to their perceived probability of genetic predisposition to cancer.

Methods:

Two hundred and forty-three (89% response rate) women with BC completed questionnaires after an initial genetic counselling visit (T1), of which 180 (66%) completed questionnaires again after receiving the BRCA1/2 results (T2). The discrepancy between women's perceived probability of cancer genetic predisposition at T1 and the geneticist's computed estimates was assessed.

Results:

In all, 74% of women received a negative uninformative (NU), 11% a positive BRCA1/2 and 15% an unclassified variant (UV) result. On hierarchical regression analysis, in women with a positive BRCA1/2 result (vs NU or UV), a lower perceived probability of cancer genetic predisposition than objective estimates at T1 predicted lower levels of anxiety at T2 (β=−0.28; P<0.01), whereas in women receiving a UV result (vs NU or positive BRCA1/2), a lower perceived probability of cancer genetic predisposition than objective estimates at T1 predicted higher levels of anxiety (β=0.20; P<0.01), depression (β=0.19; P<0.05) and intrusion (β=0.18; P<0.05) at T2.

Conclusion:

The type of BRCA1/2 test result differently affects distress according to women's perceived probability of genetic predisposition before testing.

Deaf genetic testing and psychological well-being in deaf adults

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

Genetic counseling as a tool for type 2 diabetes prevention: a genetic counseling framework for common polygenetic disorders

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

Effects of a pre-visit educational website on information recall and needs fulfilment in breast cancer genetic counselling, a randomized controlled trial

Introduction

Pre-visit education which helps counselees to prepare for their first visit for breast cancer genetic counseling might enhance information recall and needs fulfilment. This study assessed the effects of a pre-visit website with tailored information and question prompt sheet (QPS), named E-info gene^ca.

Methods

A total of 197 counselees were randomized to receive usual care (UC) or UC plus E-info gene^ca. All counselees completed a pre- and post-visit questionnaire and visits were videotaped. We studied effects on counselees' information recall, knowledge about breast cancer and heredity, fulfillment of needs, risk perception alignment, anxiety and perceived personal control, using multilevel regression analyses.

Results

Intent-to-treat analysis showed that counselees in the intervention group (n = 103) had higher levels of recall of information from the consultation (β = .32; confidence interval (CI): .04 to .60; P = .02; d = .17) and post-visit knowledge of breast cancer and heredity (β = .30; CI: .03 to .57; P = .03) than counselees in the UC group (n = 94). Also, intervention group counselees reported better fulfilment of information needs (β = .31; CI: .03 to .60; P = .03). The effects of the intervention were strongest for those counselees who did not receive an indication for DNA testing. Their recall scores showed a larger increase (β = .95; CI: .32 to 1.59; P = .003; d = .30) and their anxiety levels dropped more in the intervention compared to the UC group (β = -.60; CI: -1.12 to -.09; P = .02). No intervention effects were found after the first visit on risk perception alignment or perceived personal control.

Conclusions

This study shows that pre-counseling education, using tailored information technology, leads to more effective first visits for breast cancer genetic counseling, in particular for counselees who received no indication for DNA testing and, therefore, had no indication for a second visit. Future study should focus on the effects of a pre-visit website on the outcomes after a complete series of visits.

Patient outcomes associated with group and individual genetic counseling formats

Identifying new methods to deliver cancer genetic counseling (GC) are needed to meet the growing interest in BRCA1/2 testing. The goal of this pilot feasibility study was designed to test the initial acceptability of group GC on selected patient outcomes (satisfaction, distress, perceived control) in a breast/ovarian cancer genetics clinic setting. Sixty-five participants at increased risk for hereditary breast/ovarian cancer (HBOC) agreed to participate in self-selected individual or group GC appointments. Forty-nine participants completed all study questionnaires and were included in the analyses. There were significant improvements for participants in both the individual and group GC formats with regard to perceived personal control, general psychological distress and cancer-specific psychological distress scores. Participants in both the individual and group formats reported high satisfaction scores on the Genetic Counseling Satisfaction Scale. Study results suggest that group GC may be feasible and acceptable to high-risk women.

The introduction of a choice to learn pre-symptomatic DNA test results for BRCA or Lynch syndrome either face-to-face or by letter

In predictive DNA testing for hereditary cancer, test results should traditionally be disclosed face-to-face. Increasingly, however, counselees ask to receive their test result at home by letter. To compare the quality of genetic counselling in the traditional way to a procedure in which counselees are offered a choice on how to get their test result. Counselees from families with a known BRCA1/2 or Lynch syndrome mutation were randomised into two groups. The control group was given the DNA test result in a face-to-face consultation. In the intervention group people could choose to learn their test result face-to-face or by letter. The quality of genetic counselling was assessed through questionnaires at three different moments. Data of 198 counselees were analysed. The quality of genetic counselling and psychological functioning were equally good in both groups. The majority of cases chose for disclosure by letter. The counselees with a good test result in the intervention group were the most satisfied. Our results indicate that in predictive DNA testing for BRCA1/2 and Lynch syndrome, a choice protocol is equally safe and more satisfying. Moreover, it is more efficient for both counsellor and counselee.

Longer-term influence of breast cancer genetic counseling on cognitions and distress: smaller benefits for affected versus unaffected women

OBJECTIVE

To evaluate outcomes of breast cancer genetic counseling in women with and without breast cancer.

METHODS

Seventy-seven first-time attendees (n=44 affected) completed questionnaires assessing cognitions (risk accuracy, knowledge, perceived personal control [PPC]) and distress (state anxiety [STAI], cancer-related stress reactions [IES]) from immediately before to immediately and six months after completing counseling. Data were analyzed using multilevel repeated measures and trend analyses.

RESULTS

In affected counselees, mean cognitions did not significantly differ over time, anxiety significantly decreased, and IES levels were increased immediately post-counseling. In unaffected counselees, cognitions significantly improved over time except for knowledge. Distress levels showed similar patterns as in affected women. Improvements in cognitions and distress were significantly smaller in affected versus unaffected women.

CONCLUSION

Overall, counseling educates women about breast cancer risk and alleviates their anxiety. Importantly, benefits gained at immediate follow-up seem maintained over time.

PRACTICE IMPLICATION

Affected women seem to benefit less from counseling. Counselors may need to devote more effort into educating these women and addressing their anxieties. Future studies should confirm the unexpected finding that cancer-related distress increased immediately post-counseling.

Individualized choice in prenatal diagnosis: the impact of karyotyping and standalone rapid aneuploidy detection on quality of life

OBJECTIVE

To assess the reasons and perceptions of women who are offered a choice between karyotyping and standalone rapid aneuploidy detection (RAD) and to compare the impact of both tests on anxiety and health-related quality of life.

METHODS

In this prospective comparative study, women undergoing amniocentesis on behalf of their age or for an increased Down syndrome risk were offered a choice between karyotyping (group 1, n = 68) and standalone RAD (group 2, n = 61). Follow-up was 9 weeks post amniocentesis.

RESULTS

The most commonly cited reason for choosing karyotyping was obtaining as much information as possible, while for choosing standalone RAD, it was the short waiting time. Prenatal screening (OR 7.09), no knowledge of karyotyping (OR 4.2), and an intermediate perceived risk for chromosomal abnormalities (OR 3.6) were associated with choosing standalone RAD. There were no systematic differences in time of karyotyping and standalone RAD in terms of anxiety (P = 0.11), generic physical and mental health (P = 0.94, 0.52; P = 0.66, 0.07), personal perceived control (PPC; P = 0.69), and stress (P = 0.66).

CONCLUSION

Offering a choice between karyotyping and standalone RAD does not influence anxiety, stress, PPC, or generic health. Individual choice in prenatal diagnosis meets individual needs and thereby could reduce anxiety and stress.

The impact of rapid aneuploidy detection (RAD) in addition to karyotyping versus karyotyping on maternal quality of life

OBJECTIVE

To assess the impact of rapid aneuploidy detection (RAD) combined with fetal karyotyping versus karyotyping only on maternal anxiety and health-related quality of life.

METHODS

Women choosing to undergo amniocentesis were selected into group 1, i.e. receiving a karyotype result only (n = 132) or to group 2, i.e. receiving both the result of RAD and karyotyping (n = 181).

RESULTS

There were no systematic differences in time of RAD combined with karyotyping versus karyotyping only in terms of anxiety (P = 0.91), generic physical health (P = 0.76, P = 0.46), generic mental health (P = 0.52, P = 0.72), personal perceived control (P = 0.91) and stress (P = 0.13). RAD combined with karyotyping reduced anxiety and stress two weeks earlier compared to karyotyping only.

CONCLUSION

RAD as add-on to karyotyping reduces anxiety and stress in the short term but it does not influence overall anxiety, stress, personal perceived control, and generic mental and physical health when compared to a karyotype-only strategy.

Development, testing, and validation of a patient satisfaction questionnaire for use in the clinical genetics setting

Patient satisfaction is an important component of assessing quality of care. The purpose of this study is to develop a concise patient satisfaction tool specifically for use in the clinical genetics setting. An international survey identified two domains, "Respect Given" and "Patient Questions Answered" as being important components of satisfaction in the genetic encounter. A working group of professionals assembled a 14-question pilot questionnaire that was subsequently tested in 13 clinical sites. Nearly 400 responses were used to validate the tool and ultimately construct a 7-item questionnaire. The 7-item questionnaire was found to be reliable and valid and addresses two key components of patient satisfaction: technical aspects of care and interpersonal relations. The tool is compared to other patient satisfaction tools developed for use in the clinical genetics setting. A Spanish version is also provided.

Raising awareness of carrier testing for hereditary haemoglobinopathies in high-risk ethnic groups in the Netherlands: a pilot study among the general public and primary care providers

BACKGROUND

In the Netherlands no formal recommendations exist concerning preconceptional or antenatal testing for carriership of hereditary haemoglobinopathies. Those at highest risk may be unaware of the possibility of carrier screening. While universal newborn screening has recently been introduced, neither preconceptional nor antenatal carrier testing is routinely offered by health care services to the general public. A municipal health service and a foundation for public information on medical genetics undertook a pilot project with the aim of increasing knowledge and encouraging informed choice. Two groups were targeted: members of the public from ethnic groups at increased risk, and primary health care providers. This study examines the effectiveness of culturally specific 'infotainment' to inform high-risk ethnic groups about their increased risk for haemoglobinopathies. In addition, the study explores attitudes and intentions of primary care providers towards haemoglobinopathy carrier testing of their patients from high-risk ethnic groups.

METHODS

Informational sessions tailored to the public or professionals were organised in Amsterdam, and evaluated for their effect. Psychological parameters were measured using structured questionnaires based on the Theory of Planned Behaviour.

RESULTS

The pre-test/post-test questionnaire showed that members of the public gained understanding of inheritance and carriership of haemoglobinopathies from the "infotainment" session (p < 0.01). Perceived behavioural control, i.e. the feeling that they could actually get tested if they wanted to, increased in the targeted age group of 18-45 years (N = 41; p < 0.05). 191 surveys were collected from general practitioners or midwives. Their attitude towards the education programme for high-risk ethnic groups was positive, yet they did not show strong intention to effectuate carrier testing of their patients on the basis of ethnicity. The main factor which explained their (lack of) intention was social norm, i.e. their perception of negative peer opinion (41% variance explained). The majority of primary health care providers felt that policy change was unnecessary.

CONCLUSION

The "infotainment" programme may have a positive effect on people from high-risk groups, but informed general practitioners and midwives were reluctant to facilitate their patients' getting tested. Additional initiatives are needed to motivate primary care providers to facilitate haemoglobinopathy carrier testing for their patients from high-risk backgrounds.

Patient empowerment in clinical genetics services

Outcome measurement in clinical genetics is problematic because the patient benefits are difficult to measure. The aim in this qualitative grounded theory study was to develop a theoretical framework describing the patient benefits from using clinical genetics services. Seven focus groups and 19 interviews were conducted with patients, patient group representatives, and health professionals. Data analysis resulted in construction of a model of empowerment summarizing the patient benefits from using clinical genetics services. Empowerment is similar to the concept of perceived personal control (PPC), and a measure of PPC has been developed for use in evaluations of clinical genetics services. However, empowerment includes some benefits not captured by PPC related to empowerment of other at risk relatives, and future generations.

Design of the BRISC study: a multicentre controlled clinical trial to optimize the communication of breast cancer risks in genetic counselling

BACKGROUND

Understanding risks is considered to be crucial for informed decision-making. Inaccurate risk perception is a common finding in women with a family history of breast cancer attending genetic counseling. As yet, it is unclear how risks should best be communicated in clinical practice. This study protocol describes the design and methods of the BRISC (Breast cancer RISk Communication) study evaluating the effect of different formats of risk communication on the counsellee's risk perception, psychological well-being and decision-making regarding preventive options for breast cancer.

METHODS AND DESIGN

The BRISC study is designed as a pre-post-test controlled group intervention trial with repeated measurements using questionnaires. The intervention-an additional risk consultation-consists of one of 5 conditions that differ in the way counsellee's breast cancer risk is communicated: 1) lifetime risk in numerical format (natural frequencies, i.e. X out of 100), 2) lifetime risk in both numerical format and graphical format (population figures), 3) lifetime risk and age-related risk in numerical format, 4) lifetime risk and age-related risk in both numerical format and graphical format, and 5) lifetime risk in percentages. Condition 6 is the control condition in which no intervention is given (usual care). Participants are unaffected women with a family history of breast cancer attending one of three participating clinical genetic centres in the Netherlands.

DISCUSSION

The BRISC study allows for an evaluation of the effects of different formats of communicating breast cancer risks to counsellees. The results can be used to optimize risk communication in order to improve informed decision-making among women with a family history of breast cancer. They may also be useful for risk communication in other health-related services.

A comparison of counselee and counselor satisfaction in reproductive genetic counseling

Important insights in the process of genetic counseling can be provided by establishing levels of satisfaction. The aim of our study was to compare counselees' and counselors' satisfaction with the initial consultation in reproductive genetic counseling and to gain insight into the factors associated with their contentment. One hundred and fifty-one women and 11 counselors participated in this study. Pre-test questionnaires included counselees' socio-demographic, physical and psychological characteristics, i.e. their degree of worry, expectations, preferred participation in decision making and experienced degree of control. Post-visit questionnaires asked for counselees' and counselors' satisfaction, counselees' participation in decision making and counselees' Perceived Personal Control (PPC). Little difference was found between counselees' and counselors' overall visit-specific satisfaction (mean 79 vs 74, respectively, on a visual analogue scale from 0 to 100). The correlation between counselees' and counselors' satisfaction was medium sized (r = 0.26, p < 0.01). Counselees' satisfaction was positively associated with being pregnant and with their post-visit PPC. Counselors' satisfaction was positively associated with counselees' post-visit PPC. No other counselee and counselor related variables appeared to be associated with satisfaction, nor was the duration of the consultation. Our findings suggest that, although both groups were satisfied with the consultation, counselees and counselors do not always have equal perceptions of the consultation process and may form their evaluation in different ways. In the assessment of quality of care, evaluation of both counselees' and counselors' satisfaction deserves more attention.

Cancer genetic counseling: communication and counselees' post-visit satisfaction, cognitions, anxiety, and needs fulfillment

Little is known about the relation between communication during cancer genetic counseling and outcome. We assessed associations between counselor-counselee communication and counselee satisfaction, cognitions, anxiety, and fulfillment of major needs, corrected for pre-visit levels as appropriate. In total 171 consecutive new counselees, mainly referred for breast or colon cancer, received pre- and post-visit questionnaires assessing needs/fulfillment, knowledge, perceived control (PPC), anxiety (STAI), and satisfaction. Initial visits were videotaped and counselor eye gaze was recorded. Verbal communication was rated by Roter Interaction Analysis System (RIAS). Asking more medical questions was associated with lower satisfaction levels. Receiving more medical information was related to higher correct knowledge scores, higher reported fulfillment of some needs, and unrelated to perceptions of control. Receiving more psychosocial information and longer counselor eye gaze were related to higher anxiety scores. Longer visits were related to higher correct knowledge scores. Providing medical information appears the most powerful communication aspect to increase counselee satisfaction and address needs. More research is needed on how to address adequately (emotional) needs and increase feelings of control.

Five years of EACH (European Association for Communication in Healthcare)

Five years after launching EACH (European Association for Communication in Healthcare) we look back at what EACH achieved so far and announce new ideas and activities EACH plans to carry out in the near future. During the past five years several scientific, educational as well as societal changes have taken place in the area of communication in healthcare that all underline the need for continued international collaboration in line with the activities employed by EACH so far. Within communication research the focus has shifted from counting communication utterances to unraveling sequences of patient cues and provider responses. In the field of teaching it is becoming more and more common to attend to the training of trainers as well. Within these developments, new areas of interest arise and need attention. To comply with these increasing demands, EACH invites new persons to become a member of one of the recently launched committees in the area of research, teaching and publishing.

Adaptación española de la Escala de Control Personal Percibido ("Perceived Personal Control") en Consejo Genético

Objetivo: Analizar la validez y la fiabilidad de la adaptación de la escala Perceived Personal Control (PPC) en el contexto español para pacientes portadoras de mutación en los genes BRCA1/2 responsables del cáncer de mama y ovario hereditario (CMOH). Método: Adaptación transcultural y validación de la escala Perceived Personal Control (PPC) desarrollada por Shiloh y colaboraradores mediante traducción, retrotraducción y validación a través de un análisis factorial exploratorio con rotación Oblimin en una muestra de 176 mujeres portadoras de genes BRCA 1/2 para CMOH. Resultados: La versión española de la PPC reduce a seis los nueve ítems de la escala original, dado que esta estructura es la que ofrece una solución factorial más satisfactoria. El análisis factorial mostró un solo factor que explica el 51,07% de la varianza, en el que todos los ítems tenían cargas factoriales por encima de 0,4. El coeficiente α de Cronbach fue de 0,84 para el conjunto de la escala, la cual permite obtener valores que oscilan entre 0 (bajo grado de percepción de control) y 2 (alto grado de percepción de control). Conclusiones: La adaptación española de la Escala de Percepción de Control (PPC6) posee propiedades psicométricas satisfactorias en la versión de 6 ítems con un solo factor, por lo que su utilización en contexto español Consejo Genético para cáncer hereditario parece adecuada.
