We used MANOVA for comparisons among the predictor variables and multiple dependent variables. ¹Adjusted score difference denotes adjusted score difference between the highest scoring group and the reference group means. All differences were significant at p <= .001. ²C.I. denotes confidence interval. ³n.a. denotes not applicable.
