Management of Adolescent-Parent Dyads' Discordance for Willingness to Participate in a Reproductive Health Clinical Trial

Ethical Issues Raised by the Media Portrayal of Adolescent Transplant Refusals

Cases of adolescents in organ failure who refuse solid organ transplant are not common, but several have been discussed in the media in the United States and the United Kingdom. Using the framework developed by Buchanan and Brock for surrogate decision-making, I examine what role the adolescent should morally play when deciding about therapy for life-threatening conditions. I argue that the greater the efficacy of treatment, the less voice the adolescent (and the parent) should have. I then consider how refusals of highly effective transplant cases are similar to and different from refusals of other lifesaving therapies (eg, chemotherapy for leukemia), which is more commonly discussed in the media and medical literature. I examine whether organ scarcity and the need for lifelong immunosuppression justify differences in whether the state intervenes when an adolescent and his or her parents refuse a transplant. I argue that the state, as parens patriae, has an obligation to provide the social supports needed for a successful transplant and follow-up treatment plan, although family refusals may be permissible when the transplant is experimental or of low efficacy because of comorbidities or other factors. I conclude by discussing the need to limit media coverage of pediatric treatment refusals.

Adolescent and Parent Perceptions about Participation in Biomedical Sexual Health Trials

Given the burden of HIV and other sexually transmitted infections among adolescents who are legal minors, it is critical that they be included in biomedical sexual health trials to ensure that new prevention and treatment interventions are safe, effective, and acceptable for their use. However, adolescents are often not well represented in clinical trials. We provide an overview of the available evidence regarding adolescent and parent willingness for adolescents to participate in biomedical sexual health trials, parental involvement in the permission-consent process, management of differences and discord among adolescents and parents, and parental involvement throughout the study period. We also outline recommendations for current practice and areas for future research.

Innovative Approaches to Obtain Minors' Consent for Biomedical HIV Prevention Trials: Multi-Site Quasi-Experimental Study of Adolescent and Parent Perspectives

BACKGROUND

Despite the high burden of new HIV infections in minor adolescents, they are often excluded from biomedical HIV prevention trials, largely owing to the ethical complexities of obtaining consent for enrollment. Researchers and ethics regulators have a duty to protect adolescents-as a special category of human subjects, they must have protection that extends beyond those afforded to all human subjects. Typically, additional protection includes parental consent for enrollment. However, parental consent can present a risk of harm for minor adolescents. Research involving minor adolescents indicate that they are unwilling to join biomedical trials for stigmatized health problems, such as HIV, when parental consent is required. This presents a significant barrier to progress in adolescent HIV prevention by creating delays in research and the translation of new scientific evidence generated in biomedical trials in adult populations.

OBJECTIVE

This protocol aims to examine how parental involvement in the consent process affects the acceptability of hypothetical participation in biomedical HIV prevention trials from the perspectives of minor adolescents and parents of minor adolescents.

METHODS

In this protocol, we use a quasi-experimental design that involves a simulated consent process for 2 different HIV prevention trials. The first trial is modeled after an open-label study of the use of tenofovir disoproxil fumarate and emtricitabine as preexposure prophylaxis for HIV. The second trial is modeled after a phase IIa trial of an injectable HIV integrase inhibitor. There are 2 groups in the study-minor adolescents aged 14 to 17 years, inclusive, and parents of minor adolescents in the same age range. The adolescent participants are randomized to 1 of 3 consent conditions with varying degrees of parental involvement. After undergoing a simulated consent process, they rate their willingness to participate (WTP) in each of the 2 trials if offered the opportunity. The primary outcome is WTP, given the consent condition. Parents undergo a similar process but are asked to rate the acceptability of each of the 3 consent conditions. The primary outcome is acceptability of the consent method for enrollment. The secondary outcomes include the following: capacity to consent among both participant groups, the prevalence of medical mistrust, and the effects of the study phase (eg, phase IIa vs the open-label study) and drug administration route (eg, oral vs injection) on WTP (adolescents) and acceptability (parents) of the consent method.

RESULTS

Enrollment began in April 2018 and ended mid-September 2019. Data are being analyzed and dissemination is expected in April 2020.

CONCLUSIONS

The study will provide the needed empirical data about minor adolescents' and parents' perspectives on consent methods for minors. The evidence generated can be used to guide investigators and ethics regulators in the design of consent processes for biomedical HIV prevention trials.

A Research Agenda for Emergency Medicine-based Adolescent Sexual and Reproductive Health

OBJECTIVE

The objective was to identify key questions for emergency medicine (EM)-based adolescent sexual and reproductive health and to develop an evidence-based research agenda.

METHODS

We recruited national content experts to serve as advisory group members and used a modified Delphi technique to develop consensus around actionable research questions related to EM-based adolescent reproductive and sexual health care. Author subgroups conducted literature reviews and developed the initial list of research questions, which were iteratively refined with advisory members. External stakeholders then independently rated each item for its importance in expanding the evidence base (1 = not important to 5 = very important) via electronic survey.

RESULTS

Our final list of 24 research questions included items that intersected all sexual and reproductive health topics as well as questions specific to human immunodeficiency virus/sexually transmitted infections (HIV/STIs), pregnancy prevention, confidentiality/consent, public health, and barriers and facilitators to care. External stakeholders rated items related to HIV/STI, cost-effectiveness, brief intervention for sexual risk reduction, and implementation and dissemination as most important.

CONCLUSIONS

We identified critical questions to inform EM-based adolescent sexual and reproductive health research. Because evidence-based care has potential to improve health outcomes while reducing costs associated with HIV/STI and unintended pregnancy, funders and researchers should consider increasing attention to these key questions.

A reflection on ethical and methodological challenges of using separate interviews with adolescent-older carer dyads in rural South Africa

Background

This article discusses our reflections on ethical and methodological challenges when conducting separate interviews with individuals in dyads in the uMkhanyakude district, South Africa. Our work is embedded in an ethnographic study exploring care relationships between adolescents and their older carers in the context of a large-donor funded HIV programme. We use these reflections to discuss some of the challenges and present possible management strategies that may be adopted in conducting dyadic health research in resource-poor settings.

Methods

Drawing from the relational agency, three rounds of separate interviews and participant observation were undertaken with dyads of adolescents aged between 13 and 19 and their older carers aged 50+ from October 2017 to September 2018. A reflexive journal was kept to record the interviewer's experiences of the whole research process. We identified methodological and ethical challenges from these data during the thematic analysis.

Results

A total of 36 separate interviews were conducted with six pairs of adolescent-older carer dyads (n = 12 participants). Five themes emerged: recruitment of dyads, consenting dyads, confidentiality, conducting separate interviews with adolescents and older carers, and interviewer-dyad interaction. We also illustrated how we dealt with these challenges.

Conclusions

Results from this study can guide the recruitment, consenting and collecting data for health studies that employ a similar form of enquiry in LMICs. However, ethical and methodological challenges should be recognised as features of the relationships between cross-generation dyads rather than weaknesses of the method.

Giving adolescents a voice: the types of genetic information adolescents choose to learn and why

PURPOSE

The American College of Medical Genetics and Genomics supports parents' opting in or out of secondary analysis of 59 genes when their child has clinical exome/genome sequencing. We explored the reasons adolescents choose to learn certain types of results and the reasons they want to involve or not involve parents in decision-making.

METHODS

Adolescents recruited without clinical indication were offered independent, followed by joint choices with a parent to learn genomic results. After making independent choices, adolescent/parent dyads were interviewed to explore the reasons for their choices. Interviews were audio-recorded and transcribed. The constant comparative method was used to analyze 64 purposefully selected transcripts that included 31 from adolescents who excluded some or all potential results.

RESULTS

Three major themes informed adolescents' choices: (1) actionability of information, (2) knowledge seeking, and (3) psychological impact. Of adolescents who independently excluded some conditions (n=31), 58% changed their initial choices during the joint interview due to parental influence or improved understanding. Nearly all adolescents (98%) wanted to be involved in the decision-making process, and 53% wanted to make choices independently.

CONCLUSIONS

Our findings contribute empirical evidence to support the refinement of professional guidelines for adolescents' engagement and preferences in genetic testing decisions.

Adolescent-Parent Dyadic Retention in an Interview Study and Changes in Willingness to Participate in a Hypothetical Microbicide Safety Study

STUDY OBJECTIVE

In this study we describe adolescent and parent retention and changes in willingness to participate (WTP) in research among adolescents, parents, and adolescent-parent dyads.

DESIGN AND SETTING

Adolescent-parent dyads were recruited to participate in a longitudinal study to assess research participation attitudes using simultaneous individual interviews of the adolescent and parent with a return visit 1 year later using the same interview.

PARTICIPANTS

Adolescents (14-17 years old) and their parents.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

The relationship between participant characteristics and dyad retention was assessed. WTP was measured on a Likert scale and dichotomized (willing/unwilling) to assess changes in WTP attitudes over time for adolescents, parents, and dyads.

RESULTS

Eighty-three percent of the 300 dyads were retained. Dyads in which there was successful contact with the parent before follow-up were more likely to be retained (odds ratio, 4.88; 95% confidence interval, 2.57-9.26). For adolescents at baseline, 59% were willing to participate and 55% were willing to participate at follow-up (McNemar S = 0.91; P = .34). For parents at baseline, 51% were willing to participate and 57% were willing to participate at follow-up (McNemar S = 5.12; P = .02). For dyads at baseline, 57% were concordant (in either direction) and 70% of dyads were concordant at follow-up (McNemar S = 10.56; P = .001).

CONCLUSION

Over 1 year, parent contact might positively influence successful adolescent retention. Parents become more willing to let their adolescents participate over time, with dyads becoming more concordant about research participation.

Adolescents' and Parents' Attitudes Toward Adolescent Clinical Trial Participation: Changes Over One Year

Little is known about how adolescents' and parents' thoughts about participation in clinical trials change over time. In this study, adolescent (14-17 years)-parent dyads were asked about willingness to participate in a hypothetical reproductive health study. A year later, they were asked how their thoughts about the study had changed. Qualitative responses were coded and analyzed using framework analysis. Thirty-two percent of adolescents and 18% of parents reported changes in thoughts; reasons included general changes in perception, clearer understanding, new knowledge or experiences, increased maturity/age of adolescents, and changes in participants independent of the study. Adolescents and parents may benefit from learning about studies multiple times, and investigators should account for development and new experiences to optimize adolescent research enrollment.
