Results of a randomized controlled trial of a decision support intervention for disclosing maternal BRCA genetic test results to children and adolescents.

Objective: Evaluate the impact of a targeted family communication intervention for mothers undergoing genetic counseling and testing (GCT) for BRCA gene alterations. Methods: Following BRCA GCT, mothers (N = 204; M age = 45 y) were randomized to either a control condition (self-help print materials) or intervention (printed decision support guide, based on behavioral decision making theory in health care) for supporting choices about disclosing maternal genetic test results to children and adolescents. Behavioral assessments were administered prior to maternal GCT and after receipt of results: primary outcomes were maternal disclosure to children and parent-child communication quality. Results: Mothers in the intervention were > 2x likely to disclose their BRCA test results to their children compared to those in the control condition (odds ratio [OR] = 2.33, 95% confidence interval [CI] = 1.06, 5.10; p = .04). This effect was moderated by children's ages: mothers of preteens (<13 y) assigned to the intervention were >3x likely to disclose their results (OR = 3.74, 95% CI = 1.49, 9.41; p = .005). In adjusted models, intervention was also associated with favorable changes in the quality of parent-child communication (95% CI = 0.30, 9.00; p < .05). Conclusion: Decision support improves parent-child communication outcomes about GCT for hereditary breast-ovarian cancer. Innovation: This trial is among the first to empirically evaluate the outcomes of a behavioral intervention to support family communication of maternal BRCA risk information to children.

Clinical Impact of Pathogenic Variants in DNA Damage Repair Genes beyond BRCA1 and BRCA2 in Breast and Ovarian Cancer Patients.

Consensus guidelines for hereditary breast and ovarian cancer include management recommendations for pathogenic/likely pathogenic (P/LP) variants in ATM, CHEK2, PALB2, and other DNA damage repair (DDR) genes beyond BRCA1 or BRCA2. We report on clinical management decisions across three academic medical centers resulting from P/LP findings in DDR genes in breast/ovarian cancer patients. Among 2184 patients, 156 (7.1%) carried a P/LP variant in a DDR gene. Clinical follow-up information was available for 101/156 (64.7%) patients. Genetic test result-based management recommendations were made for 57.8% (n = 59) of patients and for 64.7% (n = 66) of patients' family members. Most recommendations were made for moderate-to-high risk genes and were consistent with guidelines. Sixty-six percent of patients (n = 39/59) implemented recommendations. This study suggests that P/LP variants in DDR genes beyond BRCA1 and BRCA2 can change clinical management recommendations for patients and their family members, facilitate identification of new at-risk carriers, and impact treatment decisions. Additional efforts are needed to improve the implementation rates of genetic-testing-based management recommendations for patients and their family members.

Pathogenicity of VHL variants in families with non-syndromic von Hippel-Lindau phenotypes: An integrated evaluation of germline and somatic genomic results.

Von Hippel-Lindau (VHL) syndrome is a hereditary tumor syndrome associated with germline loss-of-function pathogenic variants (PVs) in the VHL gene. VHL is classically associated with a high penetrance for many different tumor types. The same tumors may be sporadic in the setting of somatic VHL PVs. With more large-scale genome sequencing, variants with low penetrance or variable expressivity are identified. This has introduced challenges in patient management and the clinical interpretation of germline VHL variants identified in non-classic families. Herein, we report individuals from 3 non-classic families with VHL variants who presented with unexpected or non-syndromic phenotypes, but often with a VHL component tumor. In family 1, two siblings, age 61, with pathogenic VHL p.Leu188Val presented with clear cell renal cell carcinoma and lobular breast cancer. In family 2, the proband, age 82, was found to have pathogenic germline VHL p.Tyr98His on testing for metastatic bladder cancer. In family 3, four members carried germline VHL p.Pro81Ser (variant of uncertain significance), after the proband, age 40, presented with cerebellar hemangioblastoma. None of the individuals in the above three families met clinical criteria of classic VHL, suggesting germline VHL p.Leu188Val, p.Y98H, and p.Tyr98His may be low penetrant variants. Large studies are needed to evaluate penetrance and possible effect of genetic and non-genetic modifiers. Somatic sequencing performed on their respective tumors could help discern the etiology of the component tumors, highlighting the role of somatic evaluation in these cases. Paired examination of somatic and germline findings provided a more complete landscape of genome alterations in cancer development.

Recognizing and Managing Children with a Pediatric Cancer Predisposition Syndrome: A Guide for the Pediatrician.

It is estimated that at least 8% to 10% of children diagnosed with cancer have an inherited cancer predisposition syndrome. Pediatricians may be called upon to (1) identify children with symptoms suggestive of cancer that require further diagnostic testing, (2) identify children who should be referred to cancer genetics based on their personal and family histories, and (3) provide primary care to children who have an inherited cancer syndrome. This review article provides a list of clinical warning signs suggestive of childhood malignancy, discusses the personal and family history "red flags" suggestive of hereditary cancer, offers checklists to help identify patients who are candidates for cancer genetics evaluation, and describes features of the major pediatric cancer syndromes involving solid tumors and surveillance guidelines. This review aims to provide the pediatrician with the tools needed to recognize, refer, and help manage children at risk for pediatric cancer syndromes. [Pediatr Ann. 2018;47(5):e204-e216.].

Genetic Counselor Recommendations for Cancer Predisposition Evaluation and Surveillance in the Pediatric Oncology Patient.

As the understanding of the genetic etiology of childhood cancers increases, the need for the involvement of experts familiar with the provision of genetic counseling for this population is paramount. In October 2016, the American Association for Cancer Research organized the AACR Childhood Cancer Predisposition Workshop in which international experts in pediatric cancer predisposition met to establish surveillance guidelines for children with cancer predisposition. Identifying for whom, when, why, and how these cancer predisposition surveillance guidelines should be implemented is essential. Genetic counselors invited to this workshop provide a genetic counseling framework for oncology professionals in this article. Points of entry and recommendations regarding the provision and timing of the initial and subsequent genetic counseling sessions are addressed. The genetic counseling and testing processes are reviewed, and the psychologic impact related to surveillance is explored. Pediatric cancer genetics will continue to grow and evolve as a field, and genetic counseling services will be vital to ensure appropriate identification and management of at-risk children moving forward.

PTEN, DICER1, FH, and Their Associated Tumor Susceptibility Syndromes: Clinical Features, Genetics, and Surveillance Recommendations in Childhood.

PTEN hamartoma tumor syndrome (PHTS), DICER1 syndrome, and hereditary leiomyomatosis and renal cell cancer (HLRCC) syndrome are pleiotropic tumor predisposition syndromes that include benign and malignant neoplasms affecting adults and children. PHTS includes several disorders with shared and distinct clinical features. These are associated with elevated lifetime risk of breast, thyroid, endometrial, colorectal, and renal cancers as well as melanoma. Thyroid cancer represents the predominant cancer risk under age 20 years. DICER1 syndrome includes risk for pleuropulmonary blastoma, cystic nephroma, ovarian sex cord-stromal tumors, and multinodular goiter and thyroid carcinoma as well as brain tumors including pineoblastoma and pituitary blastoma. Individuals with HLRCC may develop multiple cutaneous and uterine leiomyomas, and they have an elevated risk of renal cell carcinoma. For each of these syndromes, a summary of the key syndromic features is provided, the underlying genetic events are discussed, and specific screening is recommended.

Cancer Screening Recommendations for Individuals with Li-Fraumeni Syndrome.

Li-Fraumeni syndrome (LFS) is an autosomal dominantly inherited condition caused by germline mutations of the TP53 tumor suppressor gene encoding p53, a transcription factor triggered as a protective cellular mechanism against different stressors. Loss of p53 function renders affected individuals highly susceptible to a broad range of solid and hematologic cancers. It has recently become evident that children and adults with LFS benefit from intensive surveillance aimed at early tumor detection. In October 2016, the American Association for Cancer Research held a meeting of international LFS experts to evaluate the current knowledge on LFS and propose consensus surveillance recommendations. Herein, we briefly summarize clinical and genetic aspects of this aggressive cancer predisposition syndrome. In addition, the expert panel concludes that there are sufficient existing data to recommend that all patients with LFS be offered cancer surveillance as soon as the clinical or molecular LFS diagnosis is established. Specifically, the panel recommends adoption of a modified version of the "Toronto protocol" that includes a combination of physical exams, blood tests, and imaging. The panel also recommends that further research be promoted to explore the feasibility and effectiveness of these risk-adapted surveillance and cancer prevention strategies while addressing the psychosocial needs of individuals and families with LFS.

Issues Arising in Psychological Consultations to Help Parents Talk to Minor and Young Adult Children about their Cancer Genetic Test Result: a Guide to Providers.

The defining difference between genetic and traditional medicine is that genetic findings have implications not just for the patient, but also for their relatives. Discussion of a test result between parent and child is both a transformative and a translational moment in the life of a family. Parents report wanting help in talking to their children. The challenge for genetic counselors and other providers is to be able to recognize which issues are at the core of parental distress and be able to offer recommendations to empower and support parents. The complexity of potential genetic findings, including variants of uncertain significance (VUS) and incidental findings have vastly increased, requiring considerable explanation and leaving less time for discussion of emotional issues. While the nature of the testing (single gene to multigene panel and genomic testing) is dramatically changing, the nature of parent concerns remains remarkably constant. Families differ in many respects, so no "recipe" suffices to answer parents' questions about how this important task should be approached in each family. Successful consultation to parents requires true counseling, matching parents' fears and questions with information, exploration and advice specific to their concerns, their circumstances and strengths.

Women's concerns about the emotional impact of awareness of heritable breast cancer risk and its implications for their children.

Women tested for mutations in BRCA1/2 genes who have minor-aged children confront difficult decisions about if, when, and how to share information about hereditary cancer risk with their children. These choices are often seemingly influenced by how mothers anticipate the emotional burdens they and their children will experience in response to test results. Here, we investigate the association between maternal cognitions, pretest psychological well-being, and coping style with mothers' anticipated emotional reactions to learning that they are BRCA1/2 mutation carriers (N = 205). In a linear regression model adjusted for maternal demographics, stronger tendencies to ruminate about information (B = .14, p = .03), greater psychological strain (B = .14, p < .001), and poorer appraisals of one's ability to cope with genetic test results conveying increased breast cancer risk information (B = -.25, p < .001) were significantly associated with anticipating more negative affect surrounding BRCA1/2 mutation identification in mothers. Our data contribute to the growing awareness of special concerns that mothers have about knowing their BRCA1/2 mutation status and highlight the need for more tailored patient education and counseling resources to improve outcomes among women at risk and their children.

Distress and the parenting dynamic among BRCA1/2 tested mothers and their partners.

OBJECTIVE: To investigate the influence of dyadic parenting relationships on psychological distress among mothers tested for BRCA1/2 genetic mutations and their untested partners. METHODS: Data were from a prospective study of mothers suspected to be at risk for hereditary breast/ovarian cancer who underwent genetic counseling and BRCA1/2 testing and their untested parenting partners (n = 109 parenting dyads). Participants completed assessments before and 1 month after genetic testing. Structural equation modeling was used to examine relationships among mothers' and partners' psychological distress, decisional conflict surrounding communication of test results to their offspring, and the parent-child communication relationship. Psychological distress was measured using items modified from the Brief Symptom Inventory. RESULTS: Among mothers, greater psychological distress (B = 0.29, p < .001) and poorer parent-child communication (B = -0.12, p < .01) at baseline predicted greater distress at follow-up. Among partners, greater distress at baseline predicted greater distress at follow-up (B = 0.67, p < .001). Mother and partner decisional conflict at baseline were equally associated with the other dyad member's distress at follow-up (B = 1.17, p < .01), but not their own distress. CONCLUSIONS: Our findings indicate that conflicted decision-making over family communication of hereditary breast/ovarian cancer genetic test results for one member of a parenting dyad adversely affects the other dyad member's psychological well-being. Interventions to improve outcomes for mothers who may be at-risk for hereditary breast and ovarian cancer and undergoing BRCA1/2 genetic testing should attend to mothers' and their partners' preferences regarding family communication about hereditary cancer risk.

Decisional outcomes of maternal disclosure of BRCA1/2 genetic test results to children.

BACKGROUND: Although BRCA1/2 genetic testing is discouraged in minors, mothers may disclose their own results to their children. Factors affecting patients' disclosure decisions and patient outcomes of disclosure are largely unknown. METHODS: Mothers (N = 221) of children aged 8 to 21 years enrolled in this prospective study of family communication about cancer genetic testing. Patients underwent BRCA1/2 genetic counseling and testing, and completed standardized behavioral assessments before and 1-month following receipt of their results. RESULTS: Most patients (62.4%) disclosed BRCA1/2 test results to their child. Patients were more likely to disclose if they received negative or uninformative versus positive results [OR = 3.11; 95% confidence interval (CI), 1.11-8.71; P = .03], their child was 13 years of age or more versus younger (OR = 5.43; 95% CI, 2.18-13.53; P < .001), and as the ratio of patients' perceived benefits of disclosure outweighed potential risks (OR = 2.40; 95% CI, 1.63-3.54; P < .001). Postdecision satisfaction about disclosure was lowest among nondisclosing patients (P < .001) and those reporting greater decisional conflict (P < .001). CONCLUSIONS: Patients commonly discuss their BRCA1/2 results with their teenage and young adult children, especially if the information is perceived as beneficial. Satisfaction with disclosure decision making remains lowest among nondisclosing and conflicted patients. Family communication decision support adjuncts to genetic counseling are needed to help ameliorate these effects. IMPACT: This study describes the prevalence of family communication about maternal BRCA1/2 genetic testing with minor children, and decisions and outcomes of disclosure.

Young adult daughters of BRCA1/2 positive mothers: what do they know about hereditary cancer and how much do they worry?

OBJECTIVE: The objectives of this study are to determine (i) what daughters, ages 18-24 years, of BRCA1/2 mutation carriers understand about their 50% chance of carrying a BRCA1/2 mutation and about risk reduction or management options for mutation carriers, (ii) the extent and nature of daughters' cancer-related distress, and (iii) the effects of knowing mother's mutation status on daughters' future plans. METHODS: A total of 40 daughters, currently aged 18-24 years, of mothers who tested positive for a mutation in BRCA1/2 were invited by mail to participate (with contact information supplied by their mothers). Daughters participated in a qualitative telephone interview about the impact of learning their mother's mutation status on their understanding of their own cancer risks and their cancer-related distress, and their knowledge of screening strategies, risk-reducing surgery, current health status, and future plans. Participants also completed study-specific demographic and family history questionnaires, the Brief Symptom Inventory-18, Impact of Event Scale (with hereditary predisposition to breast/ovarian cancer as the event), and the Breast Cancer Genetic Counseling Knowledge Questionnaire. RESULTS: Daughters' genetic knowledge is suboptimal; gaps and misconceptions were common. Over 1/3 of the daughters reported high cancer-related distress, despite normal levels of general distress. Disclosed genetic information raised future concerns, especially regarding childbearing. CONCLUSION: Targeted professional attention to this high-risk cohort of young women is critical to inform the next generation of daughters of BRCA1/2 mutation carriers and encourage recommended screening by age 25 years. Improved uptake of screening and risk reduction options could improve survival, and psychoeducation could reduce cancer-related distress.

Talking to children about maternal BRCA1/2 genetic test results: a qualitative study of parental perceptions and advice.

Family communication is the primary, initial means of educating the next, at-risk generation about hereditary cancer risk. In this study, in-depth parent narratives provided self-report of motivations, planning, satisfactions and regrets associated with sharing or not sharing maternal BRCA1/2 test results with young children and advice for parents considering disclosure and for genetic counselors. Interviews were conducted with 32 mothers tested for BRCA1/2 with children ages 8-21 years and 24 of their co-parents; interview narratives were analyzed qualitatively. Parents were concerned with both protecting and educating children about hereditary cancer risk. They expressed confidence that parents can constructively convey genetic information to minor children. Telling relieved most parents and satisfied a sense of parental duty. Parents strongly advised child-specific, age-appropriate tailoring of genetic information and emphasized conveying the positive, preventive utility of genetic information to children. Immunizing effects of disclosure were viewed as providing forewarning about and preparation for possible later family cancer diagnoses. Parents choosing not to tell children were advised to consider future disclosure. Narratives about parental sharing of BRCA1/2 test results with minor children support the feasibility of parental discussion of maternal genetic test results to the next at-risk generation. Results suggest development of intervention tools for parents would support decision-making and family communication and potentially reduce parental worry and regret. Recommendations are made for more active involvement by genetic counselors with tested parents around the topic of delivery of genetic information to children.

Parenting through genetic uncertainty: themes in the disclosure of breast cancer risk information to children.

AIM: Among mothers undergoing BRCA1/2 testing and their spouses/partners, this study sought to examine decision support needs and motivations for family communication of genetic risk information to asymptomatic children. METHODS: This study gathered data from 213 tested mothers and 104 of their untested parenting partners 1 month after maternal receipt of genetic test results and upon making a decision about communicating genetic information to their child (ages 8-21 years). Data include parents' perceived needs for family communication decision support, decision motivations, and parent-child communication. RESULTS: Parents reported high decision support needs (e.g., educational materials, professional counseling, peer assistance). Motivations for disclosure to children among mothers and partners focused on promoting the parent-child bond and maintaining family health (55.3% and 75%, respectively) and promoting positive child affect (44.7% and 25.5%, respectively). Motivations for nondisclosure to children among mothers and partners focused on the lack of appropriateness (69.6% and 51.3%, respectively) and relative importance of genetic test results (30.4% and 48.7%, respectively). Significant discrepancies in parental motivation for family communication were observed. Decision support needs were highest among disclosing mothers with affect-related motivations [t (129)=2.47; p=0.01]. Parent-child communication was poorest among nondisclosing mothers concerned about the appropriateness of genetic information for their child [t (77)=-3.29; p=.002]. CONCLUSIONS: Parents receiving information about hereditary cancer predisposition have unmet needs when making decisions about disclosing genetic risk information to their asymptomatic children. These data can guide the development of cancer risk communication decision support interventions for parents undergoing such testing.

Prevalence and correlates of mothers and fathers attending pretest cancer genetic counseling together.

OBJECTIVE: To determine the prevalence of fathers' attendance at pretest cancer genetic counseling sessions with mothers undergoing BRCA1/2 genetic testing for hereditary breast/ovarian cancer (HBOC) risk, and to identify psychosocial and other correlates of fathers' attendance. METHODS: One hundred and twenty-one fathers of minor-age children who were spouses/partners of women (mothers) undergoing such counseling and testing were recruited, completed a behavioral self-report survey, and provided data about their sociodemographic backgrounds, father-child cancer communication histories, parenting relationship quality, and information-seeking and perceived knowledge. RESULTS: A total of 27.3% of fathers attended pretest cancer genetic counseling with mothers. Compared to fathers who did not attend pretest cancer genetic counseling, those who did had stronger parenting alliances with mothers, were more likely to have sought out information about BRCA1/2 testing, and felt more informed about testing. In an adjusted logistic regression model of session attendance, the strength of the parenting alliance was associated with a 6% increase in the likelihood of attending genetic counseling (odds ratio [OR]=1.06, 95% confidence interval [CI]=1.01, 1.12, p<.05) and greater perceived knowledge about BRCA1/2 testing was associated with a four-fold increase in the likelihood of session attendance (OR=4.03, CI=1.77, 9.37, p<.001). CONCLUSION: One in three fathers attend pretest cancer genetic counseling with mothers undergoing BRCA1/2 testing; those who do have closer parenting relationships and are more informed about BRCA1/2 testing. PRACTICE IMPLICATIONS: When possible, providers should discuss mothers including fathers in cancer genetic counseling sessions as this may affect outcomes of HBOC genetic counseling and testing.

Brief assessment of parents' attitudes toward testing minor children for hereditary breast/ovarian cancer genes: development and validation of the Pediatric BRCA1/2 Testing Attitudes Scale (P-TAS).

OBJECTIVE: Predictive genetic testing for hereditary breast/ovarian cancer risk (BRCA1/2 testing) is not recommended for minor children due to its lack of immediate medical benefit and potential psychological risk. Yet, tested mothers are often interested in learning about their children's cancer risks via pediatric BRCA1/2 testing, raising a host of bioethical concerns. However, no reliable or valid tool exists to formally gauge parents' interest in such testing. The aim of this study was to develop and evaluate a new measure for use in genetic research and consultation, known as the Pediatric BRCA1/2 Testing Attitudes Scale (P-TAS). METHODS: After pretest genetic counseling and provision of a blood sample for BRCA1/2 testing, the P-TAS was administered to 187 mothers of children between 8- and 21-years-old. The measure was also given to 96 of the mothers' nontested co-parents. Analyses of the factor structure and psychometric properties of the measure were performed in mothers and confirmed in their co-parents. RESULTS: The two factors of the P-TAS, labeled Attitudes and Beliefs (Factor 1) and Decision Making and Communication (Factor 2), accounted for 62.9% of the variance and were reliable (Cronbach's coefficient alphas =.70 and .90, respectively); the structure and properties were largely confirmed among co-parents. Validity was indicated through its convergence with related constructs. CONCLUSIONS: This new tool may be integrated into genetic counseling research to better assess parents' attitudes and interests in pediatric BRCA1/2 testing. Such information may help guide ongoing discussions about the appropriateness of testing in adolescent or young adult children.

Role of parenting relationship quality in communicating about maternal BRCA1/2 genetic test results with children.

It is known that many mothers rapidly share the results of their BRCA1/2 genetic testing with their children, especially adolescent children. What is less known is the extent to which these mothers may engage fathers in a discussion concerning genetic counseling and the anticipated disclosure of genetic test results to children, or seek shared decision making in this context. This short communication addresses this issue by first examining mothers' and fathers' discussions concerning a research study of family communication. In our view, this conversation likely served as a precursor to, and proxy indicator of, maternal receptivity to partner input regarding the genetic counseling/testing-results disclosure process. We further evaluated how the quality of the parenting relationship is associated with mothers' decisions to include or not include the child's father in this study. Finally, this report addresses potential ways in which the genetic counselor may be able to facilitate parental communication regarding the evolving process of disclosure of genetic information to children and adolescents.

A novel TP53 germline mutation in a family with a history of multiple malignancies: case report and review of the literature.

OBJECTIVE: Choroid plexus carcinoma (CPC) has been associated with TP53 germline mutations and Li-Fraumeni syndrome (LFS). We describe our finding of a novel germline mutation in the TP53 gene in a family with multiple malignancies and in association with a child presenting with CPC. METHOD: An 8-month-old male presented with seizure-like activity; imaging disclosed a 1.5-cm left ventricular mass confirmed to be CPC intra- and postoperatively. Family history was significant for a half-sister who died of a primary CNS sarcoma and a paternal grandmother negative for BRCA1, BRCA2, MLH1, and MSH2 mutations with multiple (>6) LFS spectrum malignancies. RESULTS: Familial TP53 testing revealed an A-->T substitution at DNA position 13071, creating a deleterious Asn-->Ile substitution at amino acid 131 in exon 5. CONCLUSION: Physicians treating patients with CPC should be attuned to reviewing family history for risk factors suggestive of genetic cancer syndromes such as LFS. These syndromes markedly influence both the patient and family members and may alter postoperative treatment regimens.

Information needs of mothers regarding communicating BRCA1/2 cancer genetic test results to their children.

Mothers who participate in genetic testing for hereditary breast/ovarian cancer risk must decide if, when, and how to ultimately share their BRCA1 and BRCA2 (BRCA1/2) test results with their minor-age children. One of the primary aides for mothers in making this decision is cancer genetic counseling. However, counseling is limited in how well it can educate mothers about such decisions without the availability of resources that are specific to family communication and genetic testing per se. In an effort to fill this gap and identify mothers most likely to benefit from such resources, surveys were conducted with 187 mothers undergoing BRCA1/2 testing who had children 8-21 years old. Data were collected weeks after genetic testing but prior to mothers' learning of their test results; quantitative assessments of informational resource needs (i.e., speaking with previous BRCA1/2 testing participants who are parents regarding their experiences, reading educational literature about options and what to expect, speaking with a family counselor, attending a family support group, and self-nominated other resources), testing motivations, decision making vigilance, and decisional conflict regarding communicating test results to children were included. Mothers' most-to-least frequently cited information resource needs were: literature (93.4%), family counseling (85.8%), prior participants (79.0%), support groups (53.9%), and other (28.9%; e.g., pediatricians and psychologists). Seventy-eight percent of mothers were interested in accessing three or more resources. In multivariate regression analyses, testing motivations (beta = 0.35, p = 0.03), decision-making vigilance (beta = 0.16, p = 0.00), and decisional conflict (beta = 0.10, p = 0.00) were associated with mothers' need level; mothers with a greater interest in testing to learn about their children's risks, those with more vigilant decision-making styles, and those with higher decisional conflict had the greatest need. In conjunction with enhanced genetic counseling focusing on family disclosure, educational literature, and psychosocial support may promote improved outcomes.
