This article describes the development of the Resident Satisfaction Index (
RSI) to measure the quality of assisted living from the residents' perspect
ive. In total, 156 residents in 13 assisted living facilities participated
in the study. Exploratory factor analysis confirmed five hypothesized RSI s
ubscales representing resident perceptions of health care, housekeeping ser
vices. physical environment, relationships with staff; and social life/acti
vities. Cronbach's alpha for the RSI subscales ranged from .77 to .86, and
for the entire index it was .92. The correlation of the RSI with the Affect
Balance Scale (ABS) was .53, providing further support for its construct v
alidity. The instrument could be used by policy makers and professionals in
terested in improving the quality of life for the frail elderly in assisted
living.
