1. Explain the difference between a mediator variable and a moderator variable. Which of the two is more commonly seen in resilience research and why?

Expert Solution

A mediator variable can be defined as can be defined as the potential mechanism through which a predictor (independent variable) can produce changes in the criterion (dependent variable).
A moderator variable can be defined as the variable that affects the strength of relation between the predictor (independent variable) and criterion (dependent variable).
Thus a mediating variable tries to explain the relation between the predictor and criterion while moderator variable influences the strength of the relation of the predictor and criterion.

In resilience research, moderator variable is used more often and commonly than the mediator variable. This is because resilience has a moderating effect on the predictor and criterion. Resilience leads to situations being perceived as less stressful. Thus here resilience influences the strength of the relation between the criterion and predictor more than being an explanatory factor for the two.

A moderator effect occurs when the moderator (an independent variable or construct) changes the strength or even the direction of a relationship between two constructs in the model. There are two types of moderating relationships: continuous and categorical. Analyze ONE (1) major difference between continuous and categorical moderating relationships.
