Note 1. A Tolerance < .20 indicates potential multicollinearity; Since multiple subscales from the same measure were entered as predictors in the regression analyses, high intercorrelation among subscales from the same measure would be expected.

Note 2. When the regression analysis was performed using the sensory and affective subscales from the MPQ, in place of the MPQ total score, the same constellation of significant predictors resulted in the final equation.
