“…To test this hypothesis, we regressed the dependent variable on control variables as well as the five polynomial terms, which are, employee CSI (E), manager CSI (M), manager CSI squared (M2), employee CSI times manager CSI (ExM) and employee CSI squared (E2), using polynomial regressions. To reduce multicollinearity and facilitate interpretation of results, CSI values were scale-centered around the mean (Edwards, 2002;Jansen & Kristof-Brown, 2005;Shanock et al, 2010;Zhang et al, 2012). With communication satisfaction as the dependent variable, we can see from Table 3 the estimated coefficients as well as the slopes and curvatures along congruence and incongruence lines for the polynomial regressions.…”
