A moderator variable can affect the strength and direction of the relationship between a predictor and an outcome variable. This means that the relationship between the predictor and outcome variable can become stronger or weaker, or even change direction depending on the presence and level of the moderator. The strength and direction of the relationship between the predictor and the moderator may also impact the relationship between the predictor and the outcome variable. However, a moderator variable does not necessarily impact the direction of relationships with other predictor variables.
