To examine how complex, interrelated substantive and methodological characteristics across intervention studies influence effect size variation and meta-analytic validity.
Methodological critique analyzing the interdependent substantive and design characteristics across diverse intervention domains.
Evaluation of existing meta-analysis practices concerning effect size variation, generalizability, and multivariate confounding.
Interrelated substantive and methodological differences systematically correlate with study effect sizes, creating substantial risk of reporting misleading or erroneous conclusions when ignored.
Methodological reforms in meta-analytic practice are required to rigorously evaluate multivariate relationships and improve result generalizability.
