  1. Note. CFA = confirmatory factor analysis. Completely standardized factor loadings are regression coefficients obtained in predicting subscale scores when factors and subscales are both standardized. Squared multiple correlations represent the proportion of variance in each subscale that the underlying factor explains. Blank loadings were fixed at zero in the CFA model. PF = Physical Functioning. RP = Role Physical. BP = Bodily Pain. GH = General Health. MH = Mental Health. RE = Role Emotional. SF = Social Functioning. VT = Vitality.
