How to Report Mediation Analysis Results from SmartPLS and AMOS
How to Report Mediation Anlaysis
The focus of the tutorial is on how to report mediation analysis results for a research paper/thesis based on the output from SmartPLS and AMOS.

Indirect Effect: The impact of IV on DV through the mediating variable (a*b)
Total Effect: The impact of IV on DV without the involvement of the mediator (c)
Direct Effect: The impact of IV on DV in presence of the mediator (c’)
Type of Mediation: Partial or Full
Full Mediation: This form of mediation exists if the predictor (IV) exerts its total influence via the mediating variable.
Partial Mediation: This form of mediation exists if the predictor variable (IV) exerts some of its influence via Mediator. It also exerts some of its influence directly on the outcome variable and not via the mediating variable (MV). Thus the influence is exerted on the DV both through the IV and MV. So the path a*b (indirect effect) and the path c’ (direct effect) are both significant.

Sample Mediation Analysis Results
H1: Team Identify Mediates the Relationship between Corporate Social Responsibility (CSR) and Organizational Performance (OP)
Mediation analysis was performed to assess the mediating role of Team Identity in the relationship between CSR and OP. The results (see Table 1) revealed a significant indirect effect of CSR on OP (H1: β = .270, t = 5.794, p < .001). The total effect of CSR on OP was significant (β = .565, t = 13.871, p < .001), with the inclusion of the mediator the effect of CSR on OP was still significant (β = .295, t = 5.517, p < .001). This shows that Team Identity partially mediates the relationship between CSR and OP. Hence, H1 was supported.
