Toward a holistic perspective of congruence research with the polynomial regression model.
发现一致性研究常忽略检验一致性效应的所有条件，重新分析后仅三项研究支持精确匹配效应，并提出整体视角以促进多项式回归模型的正确应用，帮助学者提升理论严谨性。
. We find that congruence researchers often fail to consider all the conditions required to test congruence effects. Our reanalysis of these studies shows that when all required conditions are used, the exact correspondence effect, sometimes also labeled as the exact match effect or the perfect match effect, is only supported in three studies. Caution is hence warranted both for citing these studies as evidence of congruence and for proposing practical implications based on the findings in these studies. A holistic perspective is then proposed in this study to facilitate the proper application of the PRRSA model to help congruence scholars develop stronger theories and enhance scientific rigor in congruence research.
