The main objective of the study was to apply the recently developed Index of Capability (ICECAP-O) instrument to measure and value the quality of life of a representative sample of the older South Australian population (aged ≥ 65 years) according to carer status. A Health Omnibus survey including the ICECAP-O instrument, carer status (informal carer vs. non-carer) and several socio-demographic questions was administered in 2009 as a face-to-face interview to 789 individuals aged 65 years or older in their own homes.
