  1. * Final stepwise regression model
  2. ** Total % of variance explained: general facet = 40.3; physical health = 33.2; psychological health = 54.4%; social relations = 24.0%; environment = 43.6%
  3. *** Values of "tolerance" (cut-off score </= 0.2) and variance inflation factor (VIF - cut-off score >4.0) indicate no significant multi-collinearity.
