What’s the difference between a mediator and a moderator? A mediator variable explains the process through which two variables are related, while a moderator variable affects the strength and direction of that relationship.

Is social support a mediator or moderator?

Social support has also been theorized as a moderator, or buffer, for people experiencing stress (Cohen et al., 2000). For survivors of IPV, this model suggests that social support functions as a protective factor, mitigating the impact of abuse on women’s well-being.

What is a psychological mediator?

A mediator variable explains the how or why of an (observed) relationship between an independent variable and its dependent variable. In psychology, the mediator variable is sometimes called an intervening variable.

Is motivation a mediator or moderator?

The study measured motivation as both mediating and moderating variables in the relationship between POS and job performance. Findings showed that POS recorded a positive effect on employee job performance. However, motivation could neither establish mediating effect nor a moderating effect between the relationships.

Can mediators be moderators?

Although mediators and moderators can be integrated, it should be very clear that mediators and moderators are unique—the terms cannot be used interchangeably.

Can an independent variable be a moderator?

Level of measurement: The moderator variable is an independent variable that is used to measure the causal relationship. Like other independent variables, it may be categorized or continuous.

Can a moderator be a mediator?

Is a moderator a mechanism?

Mechanism: the basis for the effect, i.e., the processes or events that are responsible for the change; the reasons why change occurred or how change came about. Moderator: a characteristic that influences the direction or magnitude of the relationship between and independent and dependent variable.

Can a mediator also be a moderator?

Is age a mediator or moderator?

Age might be a moderator variable, in that the relation between SES and BSE could be stronger for older women and less strong or nonexistent for younger women. Education might be a mediator variable in that it explains why there is a relation between SES and BSE.

Do moderators have to be continuous variables?

– Moderation refers to a change in the relationship between an independent variable and a dependent variable, depending on the level of a third variable, termed the moderator variable. – When the predictor and moderator variables are continuous, a single product is needed to capture the moderating effect.

What is the difference between a moderator and a mediator?

Moderator vs Mediator. • Mediator identifies and explains a relationship between two variables, whereas moderator influences the strength of a relationship. • Moderator can even change the direction of relationship between two variables, namely the independent and the dependent variable.

How is a mediator related to a dependent variable?

A mediator mediates the relationship between the independent and dependent variables – explaining the reason for such a relationship to exist. Another way to think about a mediator variable is that it carries an effect.

How does a moderator affect the relationship between variables?

A moderator influences the level, direction, or presence of a relationship between variables. It shows you for whom, when, or under what circumstances a relationship will hold. Moderators usually help you judge the external validity of your study by identifying the limitations of when the relationship between variables holds.

How are mediation and moderation used in psychology?

In this way, mediators explain the causal relationship between two variables or “how” the relationship works, making it a very popular method in psychological research. Both mediation and moderation assume that there is little to no measurement error in the mediator/moderator variable and that the DV did not CAUSE the mediator/moderator.
