We conduct a meta-analysis on the existing literature integrating a large number of empirical findings of regulatory focus studies. Our study is aimed at making two important contributions to the RF literature. First, we give an overview of the impact of regulatory focus fit in terms of the magnitude of the interaction effect. Second, we identify and show the influence of potential moderators that may contribute to the magnitude of effect size: (1) feeling-right operationalization, (2) type of regulatory focus, (3) research domain, (4) use of incentives, (5) type of student sample and (6) participants’ cultural background. We employ meta-regression analysis (MRA) to assess the association between these factors and effect size heterogeneity. Findings and limitations of the study are addressed.
