This study explores the dynamics of informal care of the elderly in Mexican-American families. Quantitative and qualitative data drawn from interviews with caregivers are presented, which illustrate how acculturation affects the caregiving experience itself and its consequences in terms of stress, burden, rewards, and overall satisfaction. The burden of caregiving for both highly acculturated and less acculturated caregivers was substantial, but there were dramatic differences between the groups in levels of satisfaction. Contrary to expectations, the less acculturated caregivers experienced greater stress, burden, and significantly lower satisfaction even though they were more clearly fulfilling role obligations and they had more family members available to assist with caregiving. Implications for policy and practice are discussed. (C) 2002 Elsevier Science Inc. All rights reserved.
