Note. N = 244. Gender was coded as 0 = male, 1 = female. Title was coded as 1 = employee, 2 = supervisor, 3 = middle manager, 4 = top manager. Education was coded as 1 = high school or below, 2 = junior college, 3 = undergraduate, 4 = graduate or above. The moderation and moderated mediation hypotheses were tested simultaneously. All continuous predictors were mean-centered (Edwards and Lambert, 2007). b = unstandardized coefficient; SE = standard error; β = standardized coefficient. †p < 0.10, *p < 0.05, **p < 0.01, ***p < 0.001.
