Well-being, appraisal, and coping in African-American and Caucasian dementia caregivers: findings from the REACH study.

Although there has been considerable interest in racial differences in family caregiving for persons with dementia, most research to date has either ignored racial diversity or based conclusions on small numbers of caregivers drawn primarily from single site studies. The current study utilized participants from four sites of the REACH (Resources for Enhancing Alzheimer's Caregiver Health) multi-site study to compare well-being, appraisal, and religious coping by race. African-American (n = 295) and Caucasian (n = 425) dementia caregivers from four cities (Birmingham, Memphis, Boston, and Philadelphia) were compared in their demographics, care recipient characteristics, mental and physical health, and psychosocial coping resources including appraisal and religious coping. African-American caregivers reported lower anxiety, better well-being, less use of psychotropic medications, more benign appraisals of stress and perceived benefits of caregiving, and greater religious coping and participation, than Caucasian caregivers. Self-rated health did not differ by race, but African-American caregivers reported more unhealthy behaviors than Caucasian caregivers. Some results were specific to site, possibly due to differences in recruitment strategies, inclusion/exclusion criteria, and regional differences. Adjustment for covariates, including caregiver relationship to the care recipient, gender, age, socioeconomic status, and care recipient behavioral problems, altered few of these differences. Results are discussed in terms of their relevance to psychosocial intervention programs for ethnically diverse caregivers.

Evaluating home environments of persons with dementia: interrater reliability and validity of the Home Environmental Assessment Protocol (HEAP).

PURPOSE: This article reports on an interrater reliability and preliminary validity study of an investigator-developed tool, the Home Environmental Assessment Protocol (HEAP) for use in homes of persons with dementia. METHOD: The HEAP consists of 192 items that are summed into separate indices representing the number of hazards, adaptations, and level of clutter and comfort in eight areas of the home. Interrater reliability was examined among four raters, two environmental experts and two non-experts, who observed 22 dementia households. RESULTS: The Kappa statistic was used to evaluate agreement level for each measured item and found that agreement ranged from slight to almost perfect. Intraclass correlations (ICCs), were used to evaluate agreement level for indices. The hazard index in each room ranged from fair (0.36) to moderate (0.66) for all raters. For the adaptation, clutter and comfort indices in each room, ICCs ranged from 0.51 to 0.90 for all raters. Agreement level between expert and non-expert raters differed minimally for all indices. Adaptations to dining rooms (r= -0.080, p = 0.001), kitchens (r = -0.52, p = 0.02) and bedrooms (r = -0.76, p = 0.001) were associated with patient deficits such that more adaptations were made in homes of dependent persons. Low Mini-Mental Status Examination scores were associated with fewer hazards, more adaptations, and less clutter. CONCLUSION: Findings show that both experts and non-expert raters use the HEAP consistently. Also, measured attributes are related to cognitive and functional status in the expected direction.
