Sentence examples for mediator path from inspiring English sources

Mediation was tested using the guidelines provided by MacKinnon and Dwyer (1993) and MacKinnon, Fairchild, and Fritz (2007): we tested the effects of the independent variable to the mediator (path α) and the effect of the mediator to the dependent variable when the independent variable was taken into account (path β).

To formally test the mediation effect as described in the third step above, we will use a version of the Sobel test [ 41], which tests whether the indirect effect of intervention on the outcome through the mediator (defined as the product of the intervention to mediator path and the mediator to outcome path) is significantly different from zero.

For each potential mediator, single-mediator path models in three causal conceptualisations were considered.

In this so-called product of coefficient test, the product of coefficients from the independent variable to the mediator (a path in Fig.  1) and the coefficient from the mediator to the dependant variable adjusted for the independent variable (b path in Fig.  1) is divided by the standard error of the product to create a test statistic.

In the mediation analysis of treating multiple sexual partnerships as a potential mediator in the path of RDU and HIV infection, "multiple partnerships" was independently associated with both RDU (aOR, 1.69; 95% CI, 1.44-1.98) and HIV infection (aOR, 1.35; 95% CI, 1.06-1.71).
