Empirical comparison of health-related quality of life and subjective well-being measures in Australian adolescents
摘要
Health-related quality of life (HRQoL) and subjective well-being (SWB) are increasingly used to capture aspects of welfare beyond traditional health indicators; however, their conceptual distinction has not been fully resolved.
ObjectiveThis study examines the empirical relationships between HRQoL, measured using Child Health Utility 9D (CHU9D), EQ-5D-5L and EQ-5D-5L with psychosocial bolt-ons and SWB, measured using a 12-item Life Satisfaction Scale for Youth (LSS-Y) and the Disability Wellbeing Index (DWI), among Australian adolescents, and explores factors associated with these outcomes.
MethodsA nationwide, quota-based online survey was administered to Australian adolescents aged 15–19 years. The survey included the above instruments and sociodemographic questions. Psychometric analyses, including Spearman’s correlation, Kruskal–Wallis tests, and exploratory factor analyses (EFA), were conducted to examine interrelationships and latent structures. Regression analyses were used to identify factors associated with the outcome measures.
ResultsData were collected from 1026 adolescents (44.5% female). Of these, 510 completed the CHU9D and 516 completed the EQ-5D-5L with psychosocial bolt-ons under a randomised design; all participants completed the LSS-Y and DWI. No HRQoL dimension showed strong correlations (Spearman’s ρ > 0.60) with SWB dimensions, and EFA revealed limited overlap in latent constructs. Regression analyses identified general health, socioeconomic status, gender, migration status, and disability status as significant determinants of adolescents’ health and well-being.
ConclusionHRQoL and SWB are not interchangeable but provide complementary insights. Using both measures may offer a more comprehensive understanding of adolescents’ overall well-being.
