Ethical issues in psychiatric research on children and adolescents

Participant Recruitment Issues in Child and Adolescent Psychiatry Clinical Trials with a Focus on Prevention Programs: A Meta-Analytic Review of the Literature

Introduction: There is a strong need to conduct rigorous and robust trials for children and adolescents in mental health settings. One of the main barriers to meeting this requirement is the poor recruitment rate. Effective recruitment strategies are crucial for the success of a clinical trial, and therefore, we reviewed recruitment strategies in clinical trials on children and adolescents in mental health with a focus on prevention programs. Methods: We reviewed the literature by searching PubMed/Medline, the Cochrane Library database, and Web of Science through December 2022 as well as the reference lists of relevant articles. We included only studies describing recruitment strategies for pediatric clinical trials in mental health settings and extracted data on recruitment and completion rates. Results: The search yielded 13 studies that enrolled a total of 14,452 participants. Overall, studies mainly used social networks or clinical settings to recruit participants. Half of the studies used only one recruitment method. Using multiple recruitment methods (56.6%, 95%CI: 24.5–86.0) resulted in higher recruitment. The use of monetary incentives (47.0%, 95%CI: 24.6–70.0) enhanced the recruitment rate but not significantly (32.6%, 95%CI: 15.7–52.1). All types of recruitment methods showed high completion rates (82.9%, 95%CI: 61.7–97.5) even though prevention programs showed the smallest recruitment rate (76.1%, 95%CI: 50.9–94.4). Conclusions: Pediatric mental health clinical trials face many difficulties in recruitment. We found that these trials could benefit from faster and more efficient recruitment of participants when more than one method is implemented. Social networks can be helpful where ethically possible. We hope the description of these strategies will help foster innovation in recruitment for pediatric studies in mental health.

Altered Regional Homogeneity and Amplitude of Low-Frequency Fluctuations Induced by Electroconvulsive Therapy for Adolescents with Depression and Suicidal Ideation

Resting-state functional magnetic resonance imaging (rs-fMRI) was used to investigate the effects of electroconvulsive therapy (ECT) causing brain function changes in adolescents who suffered from depression and suicidal ideation (SI). A total of 30 patients (MDDs) and 25 healthy controls (HCs) matched by gender, age, and education level were enrolled. The amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo) were used to compare differences between HCs and MDDs at baseline, and differences in ALFF and ReHo pre/post ECT in MDDs. Pearson correlation analysis was used to evaluate the relationship between altered brain function and clinical symptoms. At baseline, MDDs showed decreased ALFF in the left inferior temporal gyrus and right amygdala, decreased ReHo in left inferior temporal gyrus, and increased ReHo in the right inferior frontal gyrus, opercular part and left middle occipital gyrus. After ECT, MDDs showed increased ALFF in the right middle occipital gyrus, decreased ALFF in left temporal pole, left inferior frontal gyrus, opercular part, and right frontal middle gyrus, increased ReHo in the right middle occipital gyrus, and left inferior temporal gyrus. Pearson correlation found HAMD scores at baseline were negatively correlated with ALFF in the left inferior temporal gyrus, and HAMD and BSSI scores after ECT were negatively correlated with ALFF in the right middle occipital gyrus. The abnormal activities of amygdala, inferior temporal gyrus and middle occipital gyrus might be related to depressive and suicidal symptoms in adolescents.

Respect for Persons in the Psychiatric Treatment of Children and Adolescents

Child and adolescent psychiatry involves simultaneously balancing duties to various vulnerable parties. Balancing autonomy and protection for adolescents is complex; state laws governing these situations often add confusion. Common prescribing patterns in child psychiatry lack robust evidence, and utilization of stimulants, atypical antipsychotics, and polypharmacy has skyrocketed. Significant concerns about distributive justice arise from alarming patterns in psychiatric treatment of vulnerable populations, like those affected by poverty, racism, adverse childhood experiences, and certain legal statuses. Principles of justice and respect for persons support the need for safe, adequate, and appropriate psychiatric treatment, including psychosocial interventions and resources, for all children.

Low dissemination rates, non-transparency of trial premature cessation and late registration in child mental health: observational study of registered interventional trials

The aim of this observational study was to explore trial premature cessation, non-publication and trial registration time in child mental health. Data were extracted for "closed" trials in Clinicaltrials.gov registry and European Union Clinical Trial Register (EUCTR) and corresponding publications of completed trials indexed in three data bases (PubMed, Scopus and Google Scholar). We restricted the extraction to the 'Behaviours and Mental Disorders' category and participants' age of 0-17 years. Outcome measures were trial completion, results reporting within a year after the trial completion, publishing an article in a peer-reviewed journal within an average time to publish (729 days), and registration time. The number of EUCTR trials was relatively small (n = 35) and with many inconsistencies. Out of 827 "closed" trials extracted from ClinicalTrials.gov, 69% were completed, 24.2% of prematurely ceased trials did not report reasons for early termination, 12.2% of the completed trials had results reported within a year, and 29.3% had an article published within 24 months after completion. Middle-sized (100-499 participants) and behavioural trials had higher chances of being successfully completed. Middle-sized and industry-funded trials were associated with results reporting. Chances for publishing an article were lower for industry-funded trials. Industry funding and drug interventions were related to timely registration. Large sample and non-industry funding were related to retrospective registration, which was recorded more often in recent years than before (we observed trials registered from 2002 until 2017). This study found low dissemination rates in the field of child mental health, with worrying under-reporting of premature termination causes. These findings indicate that more children are being subjected to unnecessary risk that comes with trial participation.

Electroconvulsive Therapy in Children and Adolescents: Clinical Indications and Special Considerations

Electroconvulsive therapy (ECT) is a well-tolerated, well-established, and efficacious treatment in adults, particularly in the setting of severe mood and psychotic disorders. In children and adolescents, however, ECT is infrequently administered and likely underutilized. Results from older studies evaluating the utility of ECT in children and adolescents were mixed, but recent studies have supported ECT treatment success in these patients, with particularly high response rates for treating depression. In this Perspectives, we discuss the current clinical indications for ECT in managing mood and psychotic disorders in children and adolescents. We then review the pretreatment evaluation and management of patients receiving ECT and examine the efficacy of ECT for those indications. We also address issues unique to children and adolescents, versus adults, that need to be considered when determining whether treatment with ECT is appropriate for a patient in this age group. Included in this context are the distinct side-effect profile in children and adolescents, ethical issues regarding informed consent, incorporating the child into the decision-making process when developmentally appropriate, and the need to take into account differing state jurisdictional processes.

Biomedical ethics and clinical oversight in multisite observational neuroimaging studies with children and adolescents: The ABCD experience

Observational neuroimaging studies with children and adolescents may identify neurological anomalies and other clinically relevant findings. Planning for the management of this information involves ethical considerations that may influence informed consent, confidentiality, and communication with participants about assessment results. Biomedical ethics principles include respect for autonomy, beneficence, non-maleficence, and justice. Each project presents unique challenges. The Adolescent Brain and Cognitive Development study (ABCD) collaborators have systematically developed recommendations with written guidelines for identifying and responding to potential risks that adhere to biomedical ethics principles. To illustrate, we will review the ABCD approach to three areas: (1) hazardous substance use; (2) neurological anomalies; and (3) imminent potential for self-harm or harm to others. Each ABCD site is responsible for implementing procedures consistent with these guidelines in accordance with their Institutional Review Board approved protocols, state regulations, and local resources. To assure that each site has related plans and resources in place, site emergency procedures manuals have been developed, documented and reviewed for adherence to ABCD guidelines. This article will describe the principles and process used to develop these ABCD bioethics and medical oversight guidelines, the concerns and options considered, and the resulting approaches advised to sites.

Therapeutic Misconception in Psychiatry Research: A Systematic Review

Therapeutic misconception (TM) denotes the phenomenon in which research subjects conflate research purpose, protocols and procedures with clinical treatment. We examined the prevalence, contributory factors, clinical associations, impact, and collated solutions on TM within psychiatric research, and made suggestions going ahead. Literature search for relevant empirical research papers was conducted until February 2015. Eighty-eight reports were extracted, of which 31 were selected, summarised into different headings for discussion of implications and collated solutions of TM. We found variable and high rates of TM (ranging from 12.5% to 86%) in some psychiatry research populations. Contributory factors to TM included perceived medical roles of researchers, media, research setting and subject factors. Greater TM in affective, neurodevelopmental and psychotic spectrum conditions were associated with demographic variables (such as lower education, increased age), clinical factors (such as poor insight, cognitive deficits, increased symptoms, poorer self-rated quality of health), and social functioning (such as decreased independence). Inattention to TM may lead to frustration, negative impression and abandonment of participation in psychiatry research. Strategies such as the employment of a neutral educator during the informed consent process and education modules may be effective in addressing TM. Further research is warranted to examine the different TM facets, specific clinical correlates and more effective management strategies.

Clinical research involving children: registration, completeness, and publication

BACKGROUND AND OBJECTIVE

Effective health care for children must be based on thorough analyses of the best research evidence. The objective of this study was to examine registration, completeness, and publication of studies involving children.

METHODS

We searched the ClinicalTrials.gov registry to identify all closed studies involving children and examined them for completeness and availability of results. We examined publication in peer-reviewed journals for 160 randomly selected National Institutes of Health (NIH)-funded studies from 2000 through 2010 and for 758 randomly selected completed studies.

RESULTS

Of 3428 closed studies involving children identified in ClinicalTrials.gov, 2385 (70%) were completed, 28 (0.8%) suspended, 152 (4.4%) terminated, and 38 (1.1%) withdrawn. The proportion of non-completed studies (terminated and suspended) increased linearly by 186% between 2001 and 2009, from 1.9% to 8.4%. Of the 152 terminated studies, 48 did not report reasons for termination, 21 cited safety concerns, and 83 cited poor recruitment or other administrative reasons. Only 29% of completed studies were published. Publication that did occur was an average of 2 years after study completion. Completed interventional studies were published more often than observational studies. Completed industry-funded studies were published less often than studies funded by the NIH. Registered NIH-funded trials were published more often than unregistered.

CONCLUSIONS

Results are unavailable for more than half of the studies involving children, revealing a substantial publication bias. Registration and posting of results on ClinicalTrials.gov should be mandatory for all studies involving children.

Child and adolescent depression: psychotherapeutic, ethical, and related nonpharmacologic considerations for general psychiatrists and others who prescribe

Depression is a common, recurring disorder affecting millions of youth at some point before they reach mature adulthood. Given the shortage of and uneven distribution of psychiatrists who have completed specialized fellowships in child and adolescent psychiatry, a significant number of depressed youth will receive their pharmacotherapy from general psychiatrists and other prescribers with varying degrees of interest, training, and even willingness to treat children and adolescents. For general psychiatrists who will prescribe antidepressants for minors, knowledge of the training and expertise of nonphysician mental health professionals, the psychotherapies they may employ, and familiarity with school services are essential. Physicians who typically work only with adults will also need familiarity with differing ethical, legal, and regulatory issues and standards applicable to pediatric psychopharmacology. General psychiatrists, pediatricians, family physicians, nurse practitioners, and others contribute greatly to the care of depressed children, adolescents, and their families, and many find this work to be a very rewarding part of their professional practices.

Ethics in child and adolescent psychiatric care: An international perspective

In the treatment of children with psychiatric disorders as a vulnerable population, ethical issues arise that seldom come into play with adults. The UN Conventions on the Rights of the Child and the Rights of Persons with Disabilities set out rights to be respected in child and adolescent psychiatric treatment. Rights of participation and inclusion (minimizing of barriers to the involvement of disabled people) can create complex problems in cases of restraint or deprivation of liberty. This paper analyses the consequences of these conventions and other ethics guidelines on child and adolescent psychiatric treatment and research. Beneficence, justice and autonomy are core principles that are mirrored in the problems of inclusion and protection, confidentiality, and the safety of psychopharmacological interventions. Factors of inclusion are involved in the areas of availability of care, participation in best evidence-based treatment, and research. The right of the child to protection, the right of inclusion, and parents' rights and duties to safeguard their child's wellbeing form a triangle. National laws to regulate the treatment of psychiatrically ill children should be created and implemented and these should be non-discriminatory but at the same time safeguard the developing human being.

Clinical ethics for the treatment of children and adolescents: a guide for general psychiatrists

Clinical work--psychotherapy, assessment, consultation, or research--with emotionally ill children and adolescents is challenging, complex, and exceedingly rewarding. Psychiatrists must remain mindful of children's vulnerabilities but also remain respectful of their rights, regardless of any legal barriers or developmental limitations that exist. To varying degrees, youths are afforded the rights of integrity, autonomy, informed consent or assent, protection of health care information, and participation in research. All physicians who work with children and adolescents are obliged to possess the requisite skills necessary for the provision of beneficial assessments, psychotherapy and psychopharmacology, the protection and advocacy that vulnerable children may require, and the ability to collaborate with families, schools, and other systems in which children regularly function. This work requires self-examination and awareness of one's values and attitudes about children and families and self-monitoring of one's motivations and intents during therapeutic interactions. Additionally, psychiatrists are reminded to seek consultation from valued colleagues whenever an ethical quandary presents itself. Finally, while negotiating the multiple requirements of children, families, communities, legal statutes, and professional ethics and standards, psychiatrists must maintain an ardent commitment to the safety and well-being of their young patients.

Ethical issues in psychiatric research

The field of psychiatric research ethics has evolved in recent years. This evolution seems to stem from the efforts of various groups (eg, medical ethicists, regulatory bodies, and the profession's own association, the APA) and from increased understanding of the endeavor of psychiatric empirical research. Current data regarding mental illness highlight the need for the continued expansion of psychiatric research to help relieve the suffering of the many individuals whom mental illness affects. The ethics for psychiatric research should parallel this expansion of psychiatric research to ensure that studies sufficiently address ethical considerations and thus foster the proper, delicate balance between progress and protection (see Table 1).

When, why, and how to conduct research in child and adolescent psychiatry: practical and ethical considerations

Changes in the clinical research enterprise to involve practicing psychiatrists in gathering evidence in real-world settings are truly exciting. The CAPTN breaks important ground as a PBRN in psychiatry. The authors anticipate that more practical clinical trials will come. These changes challenge psychiatrists to reach an entirely new level of understanding and appreciation of the ethical and practical challenges of commingling clinical practice and research. It is time that all practicing psychiatrists prepare to meet these challenges.

A review of ethics in psychiatric research

PURPOSE OF REVIEW

To summarize important recent contributions to the literature on the subject of ethics in psychiatric research.

RECENT FINDINGS

Current literature reflects an expansion in the range of psychiatric research on ethics topics. Articles continue to appear on core ethics subjects such as informed consent, but many recent contributions focus on diverse issues such as third-party privacy, the ethics of Internet-based research, revisiting the wisdom of imposing medical ethics requirements on observational research, and psychiatric research ethics as applied to special populations such as children or older persons.

SUMMARY

Psychiatric research is critical for the elucidation, prevention, and treatment of mental diseases. Increased attention and novel approaches taken to obtain informed consent, correcting therapeutic misconception, and guarding privacy will advance the research enterprise and continue to ensure that the subjective experiences of participants in psychiatric research remain positive.
