  1. Variable selection for combined models was based on including all variables from domain-specific models with p ≤ .20. Number of predictor variables were then further reduced using a stricter criterion of .10 or less. -- indicates that this variable has not been used in this regression model. Combined model for depression: n = 88. Combined model for life satisfaction: n = 102. aReverse coded for ease of interpretation. Higher values indicate better functioning (except Number of Illness and GDS)
