Dependent Variable: functional status/ R Square for the first part = 13.6%, R Square for the second part = 18.7%, Total R Square = 32.3%/ There was significant predictive ability of second part of the model (F Change (5, 181) = 4.48, P=0.001)/ a: Anxiety was removed by modeling itself, because of severe collinearity
