Purpose of the Study: Objective (physical) caregiving burden has not often been associated with subjective (emotional) burden among Mexican-origin women caregivers. Yet, many studies show that Latina caregivers suffer from negative psychological outcomes related to caregiving at a higher rate than non-Latino Whites. This study considered whether self-rated intensity of ADL/IADL support explained the relationship between number of care recipient illnesses and caregiver emotional drain among Mexican American women caregivers.; Design and Methods: Participants included Mexican-origin women caregivers (n = 132) in East Los Angeles, CA who completed a survey that asked culturally appropriate questions about their experiences caring for elderly relatives.; Results: Logistic regression models indicated that ADL/IADL supports ranked as difficult were also chosen as causing emotional drain. Mediation models revealed a significant indirect effect of number of care recipient illnesses on caregiver emotional drain for English-speaking caregivers but not for Spanish-speaking caregivers. These results indicate that Mexican-origin women caregivers do experience subjective burden associated with specific objective ADL/IADL supports and suggest that culturally relevant survey design can assist in better understanding the emotional drain among this population.; Implications: Cultural values should be considered when discussing aspects of care provision with Mexican-origin women caregivers in order to elicit an accurate description of their informal caregiving experiences that may contribute to caregiver burden.
