Purpose of the Study We examined the effect of daily stress, affect, and adult day service (ADS) use on the daily pain experience among caregivers of individuals with dementia (IWD). Participants were interviewed for 8 consecutive days. Caregivers utilized an ADS program on some days and provided care at home on other days. We hypothesized ADS use, care-related and noncare-related subjective stress, and affect would significantly influence and interact in ways to exacerbate or buffer the experience of daily pain.
