^aCorrelations between (i) continuous variables are Pearson's product moment correlations; (ii) binary variables are tetrachoric correlations; (iii) ordinal variables are polychoric; (iv) binary and ordinal variables are polychoric correlations; (v) binary and continuous variables are point-biserial correlations; and (vi) ordinal and continuous variables are polyserial correlations.

^bCR status = Co-resident status; Chr. conds. = chronic conditions; Func. lim. = functional limitations; Inf. only = informal support only; For. only = formal support only; Both = both informal and formal support; Dep. sym. = depressive symptoms (log).
