  1. BDQ physical, F = 12.2, df = 3,14, p < 0.001, R2 = 72.3% (43.9% shared predictor variance), BDQ functional, F = 10.2, df = 1,16, p = 0.006, R2 = 40.4%
  2. HDRS = Hamilton Depression Rating Scale forced entry in the regression model 1
  3. a Part R2 = part correlation squared representing unique predictor variance
  4. ns = non-significant (F to enter p < 0.05) predictor in stepwise multiple regression analyses
