Objectives

The Quality of Life-Aged Care Consumers (QOL-ACC) is an aged-care-specific preference-based instrument currently being rolled out in residential care across Australia as part of the aged care Quality Indicator program. This study aimed to provide a comprehensive assessment of the feasibility, reliability, and construct validity of the QOL-ACC in a large national sample of older adults receiving aged care services at home.

Methods

Older adults receiving in-home aged care services completed a survey including the QOL-ACC, Quality of Care Experience-ACC, adult social care outcome tool, EQ-5D-5L, and 2 global single item measures of health and quality of life. Feasibility was assessed by missing responses (≤5%) and ceiling/floor effects (≤15%). Construct validity was assessed by exploring the relationship between the QOL-ACC and other instruments (convergent validity) and its ability to discriminate varying levels of self-rated health and quality of life (known-group validity).

Results

A total of 802 respondents (mean age, 74.5 ± 6.3 years; 56.0% females) completed the survey. The QOL-ACC had no missing responses, no floor effects, and very low ceiling effect (3.5%) and demonstrated moderate correlation with adult social care outcome tool (r = 0.59, P .001). Respondents with poor self-rated health and quality of life had significantly lower preference-weighted scores on the QOL-ACC.

Conclusions

The QOL-ACC demonstrated adequate feasibility, reliability, and construct validity in a large population of older people accessing government-subsidized aged care services at home. Further studies will explore the responsiveness of the QOL-ACC to aged-care-specific interventions both in home and residential aged care settings.
