Mediating variables continue to play an important role in psychological theory and research. A mediating variable transmits the effect of an antecedent variable on to a dependent variable, thereby providing more detailed understanding of relations among variables. Methods to assess mediation have been an active area of research for the last two decades. This paper describes the current state of methods to investigate mediating variables.
中介变量在心理学理论和研究中继续发挥着重要作用。中介变量将前因变量的效应传递给因变量，从而更详细地理解变量之间的关系。在过去二十年中，评估中介作用的方法一直是一个活跃的研究领域。本文描述了研究中介变量方法的当前状况。
