  1. There were no differences in the mean/median scores in any of the five anxiety-related scales (in italics), when the nine subjects in the regression stage were compared with the 65 individuals post-regression. Interpretative guidelines for internal consistency by Cortina [53]: 0.90 or above = excellent; 0.80–0.89 = good; 0.70–0.79 = fair; below 0.70 = unacceptable. In italics are descriptive statistics for the five anxiety-related measures
