Quantifying the Voice: A Scoping Review of Metrics for Meaningful Community Involvement and Institutional Accountability in Environmental Justice and Health Equity Contexts

Review Objectives This scoping review aims to: - Identify and map existing quantifiable, quantitative, and mixed-method metrics used to evaluate meaningful community involvement in environmental justice contexts - Categorize metrics by key domains (e.g., representation, influence, power-sharing, institutional responsiveness, procedural justice) - Examine the validation status and psychometric properties of identified metrics - Assess the feasibility and applicability of metrics for use in audit rubrics or evaluation tools - Identify gaps in current measurement approaches and recommend priorities for future metric development
