Data Analysis
Separate logistic regressions were used to examine
possible predictors of receiving each of the three
health or social services — nursing, home health or
personal care, and homemaker. Ordinary least
squares regression was used to analyze the predictors
of the volume of services prescribed. Based on
the review of existing research the variables included
in the analyses were age, race, gender, household
composition, income, the receipt of informal help
for PADLand IADL limitations, PADLand IADL status,
number of disease or illness conditions, and cognitive
impairment. To account for program variations,
the county of residence was included in the analyses.
To examine whether the receipt of one service influenced
the receipt of other services, we included the
receipt of other services in the logistic regression
analyses.
