초록
This article explains theoretically and empirically the necessity of replacing Cronbach’s Alpha, which is conventionally used for reliability verification, with McDonald’s Omega. In the empirical study, How the actual reliability coefficient is estimated is explained in detail through an example, and the estimates of the two reliability coefficient were compared through a simple simulation. The overall of the use and evaluation of reliability coefficients in sports psychology research were discussed.
