Meta-Analyses

Our Meta-Analytic Process

Our meta-analyses follow a stringent, multi-step process to ensure scientific rigor and minimize bias:

• Problem Formulation: Clearly defining the research question and hypotheses.
• Literature Search: Conducting comprehensive and systematic searches across diverse databases to identify all relevant studies.
• Study Selection: Applying predefined inclusion and exclusion criteria to select studies for quantitative synthesis.
• Data Extraction: Systematically extracting relevant data (e.g., effect sizes, sample characteristics) from each selected study.
• Quality Assessment: Critically appraising the methodological quality and risk of bias of included studies.
• Statistical Synthesis: Employing appropriate statistical models (e.g., fixed-effect, random-effects) to combine effect sizes and calculate overall estimates.
• Heterogeneity Assessment: Investigating variability between study results and exploring potential moderating factors.
• Sensitivity Analysis: Assessing the robustness of findings by testing different analytical assumptions.

Impact of Meta-Analyses

Meta-analyses conducted by MakeTruth.org contribute significantly to:

• Informing Policy: Providing robust evidence to guide public policy and decision-making.
• Advancing Theory: Confirming or refuting theoretical propositions by synthesizing empirical evidence.
• Identifying Gaps: Highlighting areas where further research is needed due to inconclusive or sparse evidence.
• Resolving Contradictions: Offering clearer insights where individual studies present conflicting results.
