A Tale of Two Methods
比较了结构方程模型和Baron & Kenny两种中介效应检验方法，发现两者在检验部分中介时结果一致，但在完全中介检验上存在理论和统计估计的差异，并提出了未来检验策略。
The structural equation modeling approach to testing for mediation is compared to the Baron and Kenny approach. The approaches are essentially the same when the hypothesis being tested predicts partial mediation. The approaches differ, however, in how each tests for complete mediation. Disparities in both theory and statistical estimators are identified and discussed. A strategy for future tests of mediation is recommended.
