Note: All personality variables were entered simultaneously
Model 1: crude association
Model 2: Model 1 + demographic covariates (age, gender, race, education, living arrangement)
Model 3: Model 1 + demographic and health-related covariates (Body Mass Index, self-reported health, number of chronic illnesses, dementia, depression, anxiety, pain, and hospitalization)
