Model 1a: age, sex, race, care recipient relationship, marital status, dementia caregiving status, social network size, years of care.
Model 2a: 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.
