Bold estimates are significant with p < .05
CG caregiver, CR care recipient, 95% CI 95% confidence interval
^aIf subjective burden at baseline is excluded from the multivariate model, significant estimates are self-rated health CG (b -.330, se .154, 95% CI -.637; -.023, p .035) and household care tasks (b .061, se .022, 95% CI .016; .106, p .008)
^bresults from separate regression models, because household care tasks and personal care tasks were collinear
