Evaluation of tools to assess decision-making capacity in minor adolescents in clinical settings: a systematic review with narrative synthesis
摘要
With increasing recognition of children’s evolving decision-making capacities, assessing decision-making capacity in pediatric clinical practice has become legally and ethically important, yet no standardized assessment approach exists. The aim of this systematic review was to identify and evaluate assessment tools for decision-making capacity in children and to examine their clinical applicability and validation in pediatric populations.
MethodsWe conducted a systematic search in accordance with PRISMA guidelines across major academic databases and grey‑literature sources. Two reviewers independently screened studies and extracted data using predefined criteria. We appraised validation studies using the QUADAS‑2 tool. Due to substantial heterogeneity in study designs, populations, and outcomes, a descriptive synthesis was conducted.
ResultsA total of 27 peer‑reviewed studies and one guideline met the inclusion criteria. Across these studies, we identified seven tools: the MacArthur Competence Assessment Tools (MacCAT-T and MacCAT-CR), the Measure of Competency to Render Informed Treatment Decisions (MOC), the Maturtest, the University of California San Diego Brief Assessment of Capacity to Consent (UBACC), the Competency Questionnaire for Pediatric Population (CQ-Peds), and the Hopkins Competency Assessment Test (HCAT). The assessment tools demonstrated considerable heterogeneity in purpose, conceptual grounding, methodological approach, administration, time requirements, scoring procedures, and validation in child populations. The Maturtest, assessing moral maturity, and the child-adapted MacCAT-CR, assessing decision-making capacity in clinical research, are the only two identified validated assessment tools in a child population. One official WHO guideline was also identified.
ConclusionsWe identified seven assessment tools, assessing either moral maturity or decision-making capacity. The child-adapted MacCAT-CR remains the only validated instrument for assessing decision-making capacity in children, although mainly in research settings. No validated tool for routine clinical practice was identified, highlighting the need for clinically applicable, multidimensional assessment tools.
