Notes: N = 377 spousal caregivers. CG = caregiver; CR = care recipient; ADL/IADL = activities of daily living and instrumental activities of daily living. Estimates are presented from Step 2, which includes the covariates from Step 1 and the predictors in the same model. Interaction terms analyzed in Step 3 (R² range = 0.27–0.28) are not shown in the table for simplicity of presentation.
