Multivariable model for QoL. Potential predictor variables entered in backward stepwise linear regression analysis were CI, functional limitation, psychological distress, pain, fatigue, and white race. The final model accounts for 27% of the variation in QoL in terms of Psychological Distress, Fatigue, and white race. CI was assessed with the MoCA, scored from 0 to 30. Functional limitation was assessed with the Older Americans Resources and Services Multidimensional Assessment; higher scores indicate greater functional limitation, with a maximum of 26 points. Psychological distress was assessed with the Patient Health Questionnaire-4; higher scores indicate greater psychological distress, with of a maximum of 12 points. Pain was assessed with the Iowa Pain Thermometer; higher scores indicate more pain, with a maximum of 12 points. Fatigue was assessed with the Functional Assessment of Chronic Illness Therapy Fatigue Scale; higher scores indicate more fatigue, with a maximum of 52 points.
