Measuring the impact of increased exercise on quality of life in older adults: the UQQoL, a new instrument.

Abstract

The University of Queensland Quality of Life instrument (UQQoL) was developed to provide a quantitative measure sensitive to the impact of increased exercise on the quality of life (QoL) of older individuals. This paper describes the development and testing of the UQQoL including an exploratory study of focus group interviews with 18 participants aged 65 and over, item development and selection, and instrument piloting with groups of older adults undergoing high-intensity training. The SF-36, another established QoL tool, was also administered at the same time points for comparative purposes. The UQQoL displayed good convergent validity with selected SF-36 domains. A significant change in QoL following training was found, complementing functional improvements. This change was not detected by the SF-36. While broader testing is required, the UQQoL appears to be a reliable instrument sensitive to the change in QoL experienced by healthy community-dwelling older adults following resistance exercise.
