Purpose
This study explores the factor structure of the interRAI self-report nursing home quality of life survey and develops a measure that will allow researchers to compare predictors of quality of life (QOL) across resident, family, and staff perspectives.
Methods
Nursing home residents (N = 319), family members (N = 397), and staff (N = 862) were surveyed about their perceptions of resident QOL. Exploratory factor analyses were conducted on a random half of the staff data. Subsequently, confirmatory factor analysis was used to test for measurement equivalence across the three perspectives.
Results
The final model had a four-factor structure (i.e., care and support, food, autonomy, and activities) across all three perspectives. Each factor had at least two items that were equivalent across all three perspectives, which suggests at least partial measurement equivalence.
Conclusion
The finding of partial measurement equivalence acknowledges there are important differences between perspectives and provides a tool that researchers can use to compare predictors of QOL, but not levels of agreement across perspectives. Targeting these four aspects is likely to have the additional benefit of improving family and staff perceptions of resident QOL in addition to the resident’s own QOL.
