Research Article: Quality of life in south-eastern Australia: normative values for the WHOQOL-BREF in a population-based sample of adults

Date Published: 2023-12-10

Abstract:
Objectives The abbreviated World Health Organisation Quality of Life tool (WHOQOL-BREF) is a short-form quality of life (QoL) assessment commonly used worldwide in both healthy and ill populations. Normative data for the Australian general population are limited. The objective of this study was to present normative data for the WHOQOL-BREF based on a general population sample. A secondary aim was to explore sociodemographic factors related to QoL. Design Population-based cross-sectional study. Participants 929 men and 830?women aged 24–94 years participating in the Geelong Osteoporosis Study. Outcome measures The 26-item WHOQOL-BREF. Results Means and SD for each domain are presented by age group and sex. Percentile scores were also generated. Mean scores for WHOQOL-BREF domains were 74.52 (SD=16.22) for physical health, 72.07 (SD=15.35) for psychological, 72.87 (SD=18.78) for social relationships and 79.68 (SD=12.55) for environment. We identified significant associations between sociodemographic factors and WHOQOL-BREF domains. Notably, being married or in a relationship was associated with increased odds for high QoL across all four WHOQOL-BREF domains: physical health (women OR 2.46, 95%?CI 1.36 to 4.44, p=0.003), psychological (men OR 2.07, 95%?CI: 1.20 to 3.55, p=0.009; women OR 2.15, 95%?CI 1.21 to 3.81, p=0.009), social relationships (men OR 2.28, 95%?CI 1.29 to 4.04, p=0.005; women OR 2.77, 95%?CI 1.42 to 5.41, p=0.003) and environment (women OR 2.07, 95%?CI 1.13 to 3.80, p=0.019). Conclusions This study provides population norms for the WHOQOL-BREF based on a representative sample of Australian adults. Our results will be useful to researchers and clinicians who can use these data as a reference point for interpreting WHOQOL-BREF scores.

Introduction:
Quality of life (QoL) is an interdisciplinary concept that has gained prominence over the years as an important outcome measure in healthcare. The WHO defines QoL as an individual’s ‘perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns’. 1 Thus, QoL can be understood as a subjective evaluation encompassing multiple aspects of people’s lives. Measures of QoL are increasingly being utilised in both…
