Model 1b: age, sex, race, care recipient relationship, marital status, dementia caregiving status, monthly social contact, years of care.
Model 2b: Model 1a + PSS + caregiving strain.
Standardized regression coefficient calculated by multiplying regression coefficient by the ratio of standard deviations of the predictor to the outcome (PAC); indicates effect size. R2 indicates proportion of variance in PAC explained by predictors in each model.
