To further explore the impact of HRQOL on the relationship between multi-morbidity and depressive symptoms, the PF, RP, BP and GH domains were simultaneously used in the mediation analysis to allow comparison of the strength of the mediation effects (contrast) of each domain.
This method allowed us to represent the strength of the mediation on a continuum of 0 to 100% rather than categorically as to whether mediation occurred or not.
When partial mediation was shown, the Sobel test statistic [ 51] was used to test the strength of the mediation.
The mediated effect (a*b) provides an estimate of the relative strength of the mediation effect.
However, in addition, it tests the strength of the mediation using Sobel-Goodman test (Sobel, 1982; MacKinnon et al., 2002).
To evaluate the strength of the mediation effects, we will compute the ratio of the unstandardized betas for treatment assignment (beta from regression III divided by beta from regression II) with values less than 1.00 indicating potential mediation.
In an alternate mediation model, an interaction term of the possible mediating factor and the recovery indicator was also included in the mediation analysis to account for the possibility of moderated mediation, i.e. that the strength of the mediated relationship is contingent on the value of the recovery indicator [78 80].
Generally, the more issues from both sides of the ladder are considered in a mediational study, the more valid conclusions can be drawn about mediation relations and the strength of evidence.

"It was itself a form of mediation".
And the most important part of mediation?
