Regression Handout Spring 2015 WFC, FWC, verbal expression of emotion and psychological strain

Multiple Linear Regression Objective: examine the unique and collective association of several independent variables (or predictor variables) to one dependent variable (also called criterion variable). – Both IVs -predictor(s) and criterion-DVs are continuous. – Categorical variables with only two levels can be used as predictors-IVs

Moderation Verbal expression of emotions moderates the relation of WFC to psychological strain How so?

Moderation Moderator: Verbal Expression of Emotion Predictor: WFC (high versus low level) Relation (+ - ; strength) of WFC to strain among people with high verbal Exp of emotion (high = 1 SD above the mean) Versus Relation (+ - ; strength) of WFC to strain among people with low Verbal Exp of Emotion (low = 1 SD below the mean)

the positive relation of WFC to psychological strain will be less strong among workers who report higher (vs, lower) levels of verbal expression of emotions

the positive relation of FWC to psychological strain will be less strong among workers who report higher (vs. lower) levels of verbal expression of emotions

Moderation: Opposite direction

Both Positive Relations

Positive Relation & No Relation
