The mediation effect size measure u was adopted for this situation. A simulation study was conducted to investigate the performance of its estimators. We manipulated several factors in data generation (number of groups, sample size per group, and effect sizes of paths) and ...
Effect size measures for mediation models: quantitative strategies for communicating indirect effects. The statistical analysis of mediation effects has become an indispensable tool for helping scientists investigate processes thought to be causal. Yet, in s...

The purpose of this study was to test the effects of company size on the strength of the relationship between TQM and organisational performance. Based on a cross-sectional study of manufacturing firms in Australia and New Zealand, the paper tests two hypotheses involving TQM and organisational per...

Mediation-analysis When we analyse results of an experiment, we are often interested in understanding how the effects of our treatment/intervention came to be. That is, are there any intermediate variables (mediators) in our data that have affected our final outcome of interest as a result of ...
Full size table SEM reliability, validity, and presupposition testing As shown in Table 2, all CR values were > 0.6, indicating a satisfactory level of internal consistency. Concerning the discriminant validity analysis, Table 3 shows that the square root of the AVE value of each construct was...
Mediation analysis is routinely adopted by researchers from a wide range of applied disciplines as a statistical tool to disentangle the causal pathways by which an exposure or treatment affects an outcome. The counterfactual framework provides a language for clearly defining path-specific effects of in...
