# Hayes Process Macro - Model 6 - Serial Mediation Analyses

### Hayes Process Macro - Lecture Series

The tutorial will guide on Model 6 of the Hayes Process Macro for Serial Mediation.

## Model 6

- Serial mediation
**hypothesises a causal chain linking of the mediators.** - Example Variables: 1 predictor X, 2 Mediators M, and 1 Outcome Y
- The variables are continuous.
**Note: Model 6 allows up to 4 mediators operating in serial.**

## Example

- We want to examine if the construct of Culture has an
**indirect effect**through Assurance and Perceived Organizational Support on the construct of Organizational Performance. Further the moderating effect of Role Ambiguity is also assessed on the linkage between Culture and Organizational Performance

- Indirect effect of Culture on Performance through Commitment: a1*b1
- Indirect effect of Culture on Performance through Assurance: a2*b2
- Indirect effect of Culture on Performance through Commitment and Assurance: a1*d*b2

## How to Run

- Step 1: Analyze -> Regression -> Process v4.0 by Andrew F. Hayes

- Step 2: Put in the Required Variables. In this case,
- Y Variable (Dependent Variable) is OP
- X Variable (Independent Variable) is Culture
- Mediators are Assurance (ASR) and Commitment (COM)
- Model Number is 6

- Step 3: Select Option Button, and Choose the options as shown in the figure below ()
**Select Show total effect model (only models 4,6,70,81, 82),**this is to generate total effect estimates.- For Standardized effect, select Standardized effects (mediation-only models).

## Output Interpretation - Basic Summary

## Output Interpretation - Model Summary

- Model Summary, provides summary of the model with R, R-Sq, F Statistics, and P value for the overall model.
- Next, Model summary for each outcome variables is presented.
- First, the outcome variable is Commitment. Culture has a significant impact on Commitment (b = 0.6041, t = 14.1355, p < 0.001). This is path a1.
- Culture has a significant impact on Assurance (b = 0.2616, t = 4.6362, p < 0.001). This is path a2.
- Commitment has a significant impact on Assurance (b = 0.4579, t = 8.0511, p < 0.001). This is path d.
