Data were collected from 252 coresident caregiving daughters and daughters-
in-law and their husbands. We hypothesized that biological children would g
ive more care than children-in-law and that children-in-law would have very
different caregiving experiences and resultant appraisals than biological
children. Contrary to our hypotheses, we found that the experiences are ver
y similar for biological children and children-in-law in caregiving familie
s. We suggested that the important factor is not the relationship to the el
der that has the impact-it is the quality of the relationship with the elde
r that is consistently significant.
