Mediation analysiscan be performed using appropriate multiple regression models or covariance structure analysis, also named structural equation modeling (SEM;Kline, 1998). The first approach can be performed using standard statistical software and involves the estimation of a series of regression models ...
Effect size measure for mediation analysis with a multicategorical predictordoi:10.3389/fpsyg.2023.1101440SAMPLE size (Statistics)Many currently available effect size measures for mediation have limitations when the predictor is nominal with three or more categories. The mediation effec...

Sample size calculation The sample size was calculated using an online sample size calculation software, namely, Monte Carlo Power Analysis for Indirect Effects. Model 6 is selected to calculate the sample size. A minimum sample size of 460 cases was considered sufficient to achieve statistical power...
