Essay on the Empirical Grounding of Ford’s PHCRP Commentary and Williams’ CRF Study

In public health research, the use of race and ethnicity as variables has long been fraught with conceptual and methodological challenges, prompting critical examinations like Chandra L. Ford and Whitney N. L. Pirtle’s commentary in the American Journal of Epidemiology (2025) and Christopher Williams’ Critical Race Framework Study (2024). Ford’s commentary leverages Public Health Critical Race Praxis (PHCRP) to critique the inconsistent and often omitted use of race and ethnicity in epidemiology, advocating for antiracist methods to address health inequities. Williams’ Critical Race Framework (CRF) develops a structured tool to appraise studies using racial taxonomy, emphasizing reliability, validity, internal validity, and external validity. This essay evaluates the empirical grounding of these two works, defends the position that Williams’ CRF is more empirically grounded, and discusses the components of empirical grounding and its importance in scientific inquiry.

Understanding Empirical Grounding

Empirical grounding refers to the extent to which a study or argument is supported by observable, measurable evidence derived from systematic data collection and analysis. It is a cornerstone of scientific inquiry, ensuring that claims are not merely theoretical or anecdotal but are substantiated by rigorous, reproducible methods. Key components of empirical grounding include:

1. Data Collection: The use of systematic methods (e.g., experiments, surveys, observational studies) to gather data that directly address the research question.

2. Methodological Rigor: The application of clear, replicable procedures, including defined protocols, validated instruments, and appropriate statistical or qualitative analyses.

3. Evidence-Based Conclusions: Claims that are directly supported by the collected data, with transparent reporting of findings and limitations.

4. Reproducibility: The ability for other researchers to replicate the study using the same methods and achieve similar results, ensuring reliability.

5. Falsifiability: The capacity for claims to be tested and potentially disproven, aligning with the scientific principle of testability.

Empirical grounding matters because it establishes credibility, reduces bias, and ensures that research contributes meaningfully to knowledge and practice. In public health, where findings inform policy, interventions, and resource allocation, empirical grounding is critical to avoid misinformed decisions that could exacerbate health inequities or waste resources. For research addressing race and ethnicity, empirical grounding is particularly vital to counter the historical misuse of these constructs as biological proxies, which has perpetuated harm and scientific error.

Empirical Grounding of Ford’s PHCRP Commentary

Ford’s commentary critiques the omission and variability in race and ethnicity variables in epidemiologic research, drawing on Martinez et al.’s (2023) systematic review of 1,050 articles published between 1995 and 2018. The review found that 19%–32% of studies lacked race data and 34%–61% lacked ethnicity data, with significant variability in conceptualization and operationalization. Ford uses these findings to argue for PHCRP, a framework rooted in Critical Race Theory (CRT), which emphasizes race consciousness, structural racism, and marginalized perspectives to improve research rigor and address health inequities. The commentary offers recommendations, such as adopting PHCRP’s antiracism lexicon, using validated measures, and enforcing journal guidelines on race/ethnicity reporting.

Strengths in Empirical Grounding

Ford’s commentary is empirically grounded in its reliance on Martinez et al.’s systematic review, which provides robust data on the state of race and ethnicity in epidemiology. The review’s methodology—random sampling, clear inclusion criteria, and analysis across five time strata—ensures a reliable evidence base. Ford’s critique of the field’s “ironic lack of rigor” is directly supported by these findings, lending credibility to the argument that current practices are deficient. Additionally, the commentary’s recommendations are falsifiable in principle, as researchers could test whether adopting PHCRP improves research outcomes, such as by reducing variability in race/ethnicity measures or better capturing structural racism’s effects.

Weaknesses in Empirical Grounding

Despite its foundation in Martinez et al.’s data, the commentary’s empirical grounding is limited by its conceptual nature. Ford does not present new data or test PHCRP’s effectiveness empirically. The recommendations—while theoretically sound—are not accompanied by evidence of their feasibility, acceptability, or impact. For instance, the call to use PHCRP’s lexicon or diversify the profession lacks data on implementation outcomes or barriers. The commentary also does not specify a standardized protocol for applying PHCRP, which undermines reproducibility. Furthermore, the reliance on CRT, which Williams critiques for lacking methodological clarity, introduces ambiguity, as PHCRP’s principles (e.g., race consciousness, praxis) are not operationalized in a testable manner. This limits the commentary’s ability to meet the criteria of methodological rigor and reproducibility, key components of empirical grounding.

Empirical Grounding of Williams’ CRF Study

Williams’ CRF study develops a bias tool to critically appraise public health studies using racial taxonomy, focusing on four principles: reliability, validity, internal validity, and external validity. The study comprises three phases: a pilot study (Phase I) to assess the CRF’s fit, a national cross-sectional survey (Phase II) to evaluate perceptions and validity, and article critiques (Phase III) to test reliability and study quality. The study recruited 30 public health experts, finding that the CRF was acceptable and feasible, with moderate to high interrater agreement, excellent content validity, but inconclusive results for construct validity and interrater reliability due to sample size and significance testing issues. Phase III revealed that 20 health disparities and behavioral health studies showed low quality or no discussion of racial constructs when evaluated with the CRF.

Strengths in Empirical Grounding

The CRF study excels in empirical grounding due to its systematic, evidence-based approach. The three-phase design demonstrates methodological rigor, with clear protocols for data collection (surveys, article critiques), validated instruments (e.g., Content Validity Index, kappa), and statistical analyses (e.g., exploratory factor analyses, interrater agreement). Phase I’s pilot study tested the CRF’s acceptability, feasibility, and appropriateness, yielding quantitative and qualitative data to refine the tool. Phase II’s national survey provided robust evidence of implementation effectiveness, with acceptable thresholds for fit measures. Phase III’s critiques of 20 studies directly tested the CRF’s ability to identify biases, supporting falsifiability by showing that race-based studies often fail to meet scientific standards. The study’s transparency in reporting limitations (e.g., small sample size, inconclusive reliability) further enhances its credibility. The CRF’s standardized tool and web-based training ensure reproducibility, as other researchers can apply the same methodology.

Weaknesses in Empirical Grounding

The CRF study’s empirical grounding is not without flaws. The small sample size (30 experts) limits statistical power, particularly for interrater reliability, where results were inconclusive due to significance testing issues. Construct validity for reliability and validity items was poor to fair, and internal/external validity results were inconclusive, indicating gaps in fully capturing these constructs. These limitations weaken the study’s ability to provide comprehensive evidence for the CRF’s effectiveness. Additionally, the narrow focus on racial taxonomy may restrict generalizability, though this is a deliberate delimitation rather than a flaw in empirical design.

Defense of Williams’ CRF as More Empirically Grounded

Williams’ CRF study is more empirically grounded than Ford’s PHCRP commentary due to its systematic data collection, methodological rigor, and direct testing of claims. The CRF study meets all five components of empirical grounding to a greater extent:

1. Data Collection: The CRF study actively collects data through surveys and article critiques, directly addressing the research questions about the tool’s fit, reliability, and validity. Ford’s commentary relies on secondary data (Martinez et al.), without generating new evidence.

2. Methodological Rigor: The CRF’s three-phase design, with validated instruments and statistical analyses, ensures a structured approach. Ford’s commentary lacks a specific methodology, relying on conceptual arguments.

3. Evidence-Based Conclusions: The CRF’s findings—e.g., high content validity, low quality of race-based studies—are directly tied to collected data. Ford’s recommendations are theoretically derived, not empirically tested.

4. Reproducibility: The CRF’s standardized tool and training enable replication, while PHCRP’s lack of a specific protocol hinders consistent application.

5. Falsifiability: The CRF’s claims are tested through article critiques, demonstrating that race-based studies often fail scientific standards. Ford’s recommendations are testable but untested, limiting their empirical weight.

While Ford’s commentary provides a strong theoretical foundation and leverages Martinez et al.’s data, its empirical grounding is constrained by its conceptual nature and lack of direct evidence. The CRF study, despite limitations like sample size, actively tests its claims, making it more aligned with scientific principles. The CRF’s empirical approach also addresses a critical gap in public health literature—a standardized tool for appraising race-based research—whereas PHCRP remains a framework awaiting empirical validation.

Why Empirical Grounding Matters

Empirical grounding is essential in public health research, particularly for contentious issues like race and ethnicity, for several reasons:

1. Credibility and Trust: Empirically grounded research builds trust among researchers, policymakers, and communities by demonstrating that claims are based on rigorous evidence, not assumptions or ideology. This is crucial for addressing health inequities, where mistrust in science is high among marginalized groups.

2. Reducing Bias: Systematic data collection and analysis minimize biases inherent in theoretical or anecdotal claims. For race-based research, empirical grounding counters the historical misuse of race as a biological construct, ensuring that findings reflect social realities like structural racism.

3. Informing Policy and Practice: Public health decisions, from funding allocations to intervention design, rely on evidence-based research. Empirically grounded studies ensure that policies address actual needs, as seen in Williams’ CRF identifying low-quality race-based studies that could mislead policy.

4. Advancing Knowledge: Empirical grounding ensures that research contributes to cumulative knowledge by providing testable, reproducible findings. Ford’s PHCRP offers a theoretical roadmap, but without empirical testing, its impact on knowledge advancement is limited compared to the CRF’s validated tool.

5. Ethical Responsibility: In public health, where research affects vulnerable populations, empirical grounding is an ethical imperative to avoid harm from poorly substantiated claims. The CRF’s evidence-based critique of race-based studies aligns with this responsibility by exposing biases that could perpetuate inequities.

Conclusion

Both Ford’s PHCRP commentary and Williams’ CRF study address the critical issue of race and ethnicity in public health research, but the CRF study is more empirically grounded due to its systematic data collection, methodological rigor, and direct testing of claims. Ford’s commentary provides a valuable theoretical framework supported by Martinez et al.’s data, but its lack of empirical testing and standardized protocols limits its scientific robustness. Empirical grounding is vital to ensure credibility, reduce bias, inform policy, advance knowledge, and uphold ethical standards, particularly in the sensitive domain of race-based research. By integrating the CRF’s practical, evidence-based tool with PHCRP’s systemic, race-conscious perspective, future research could achieve both empirical rigor and transformative impact in addressing health inequities.

Empirical Grounding and Scientific Quality: A Comparative Analysis

Introduction

Empirical grounding is central to scientific quality. To be empirically grounded, a study must draw on observable, replicable evidence, utilize rigorous methods of data collection and analysis, and justify its conclusions through systematic inquiry. This essay assesses and compares the empirical grounding and scientific quality of two critical race health studies: Ford and Pirtle's commentary on PHCRP and Williams’ dissertation on the Critical Race Framework (CRF). I argue that while both works offer important conceptual contributions, Williams’ dissertation demonstrates stronger empirical grounding. I will defend this assessment and discuss what constitutes empirical grounding and why it matters for scientific advancement.

What Constitutes Empirical Grounding?

Empirical grounding refers to a research work’s dependence on:

• Data Collection: Gathering information systematically rather than relying only on theory or opinion.

• Operationalization of Constructs: Clear, replicable definitions and measures.

• Rigorous Analysis: Quantitative or qualitative analysis with documented methodology.

• Reproducibility: Procedures that others can replicate.

• Validity and Reliability: The degree to which measures accurately and consistently capture the phenomena of interest.
  
  

Without these components, research risks being speculative or ideological, and loses the credibility necessary for informing practice and policy.

Analysis of Ford and Pirtle's Commentary (PHCRP)

Ford and Pirtle’s commentary is based on their reflections on Martinez et al.’s empirical review of race and ethnicity in epidemiologic research. They draw on Public Health Critical Race Praxis (PHCRP), an applied offshoot of Critical Race Theory (CRT).

Strengths:

• Identifies real issues (lack of clarity, underuse of critical frameworks, poor operationalization).

• Provides thoughtful recommendations (e.g., use of validated measures, critical theory integration).
  
  

Limitations:

• No new empirical study: It interprets existing research rather than producing new primary data.

• Theoretical emphasis: The analysis relies heavily on theoretical critiques (e.g., racism’s ordinariness, racialization processes) rather than new, direct empirical tests.

• Indirect grounding: The data cited comes from Martinez et al., not from Ford and Pirtle’s own investigation.
  
  

Thus, while the commentary is valuable conceptually and normatively, it is less empirically grounded by itself.

Analysis of Williams' Dissertation (Critical Race Framework)

Christopher Williams’ dissertation, The Critical Race Framework Study, is designed specifically to develop and empirically validate a tool to critically assess race variables in public health studies.

Strengths:

• Original data collection: Conducted three empirical phases — pilot study, national cross-sectional survey, and article critique.

• Detailed methodology: Clear operational definitions, use of validity and reliability testing (e.g., Content Validity Index (CVI), Exploratory Factor Analysis (EFA)).

• Measures and Metrics: Assessed interrater reliability, thematic analysis, missingness, internal consistency.

• Structured improvement: Used pilot results to refine instruments for subsequent phases.

• Transparency about limitations: Explicitly acknowledges the inconclusive results regarding internal and external validity, and the need for further refinement.
  
  

Limitations:

• Sample size limitations: Small participant pool (30 experts) affects generalizability.

• Incomplete internal and external validity findings: Some results, like interrater reliability, were inconclusive.

Nevertheless, Williams' work represents a significant empirical undertaking that contributes a replicable tool (CR Framework) for improving research rigor in racial health disparities.

Defense of Decision: Williams’ Work Is More Empirically Grounded

While Ford and Pirtle provide a critical theoretical intervention, Williams performs structured empirical testing of a new tool aimed at solving a concrete problem. He generates original data, applies standardized tests of reliability and validity, and refines his model based on empirical findings — the hallmarks of scientific inquiry.

Thus, in terms of empirical grounding and scientific quality:

• Ford and Pirtle: Excellent conceptual contribution, low empirical grounding.

• Williams: Strong empirical grounding, with acknowledged areas for improvement.

This is not a dismissal of Ford and Pirtle’s work — empirical studies often need theoretical critiques to challenge assumptions and guide future research. However, when asking which is more empirically grounded, the evidence clearly favors Williams.

Why Empirical Grounding Matters

Empirical grounding matters because:

• Accountability: Empirical results hold researchers accountable to evidence, not ideology.

• Replicability: It allows others to verify or challenge findings.

• Policy relevance: Public health interventions rely on trustworthy data, not purely normative arguments.

• Scientific progress: Testing, refinement, and falsification are possible only when claims are grounded in observable data.

Empirical grounding ensures that critical theories like CRT or PHCRP can move from abstract critiques to tangible improvements in health outcomes and scientific standards.

Conclusion

Both Ford and Pirtle’s commentary and Williams’ dissertation make meaningful contributions to the critical evaluation of race in public health research. However, Christopher Williams’ Critical Race Framework stands out for its robust empirical grounding. It offers a tested, if still evolving, tool for advancing scientific quality in research involving racial constructs. In an era when both theory and evidence are crucial, empirically grounded innovation is necessary to improve scientific rigor and address systemic biases effectively.
