Abstract

AIM:

This study investigated the relationship between quality of life (QoL) and health-related quality of life (HRQoL) and assessed factors other than health that contribute to differences in QoL in young males with Duchenne muscular dystrophy (DMD).

METHOD:

In this cross-sectional study, QoL and HRQoL measures were completed by 98 parents and 85 children. The Quality of My Life (QoML) questionnaire measured QoL and HRQoL as single-items, and the Pediatric Quality of Life 4.0 Generic Core (PedsQL) questionnaire was used as a multidimensional measure of HRQoL. Simple regression was used to examine the relationship between single-item measures of HRQoL and QoL. Multivariable regression was used to investigate factors that may contribute to difference in QoL and HRQoL.

RESULTS:

While ratings of QoL and HRQoL were significantly correlated with one another, HRQoL only accounted for 21% and 44% of the variability in QoL by child- and parent-reports respectively. None of the factors measured contributed ratings of the child's QoL to be much higher than HRQoL.

INTERPRETATION:

QoL and HRQoL are related but distinct constructs as rated by children with DMD and their parents. Further research is needed to elucidate factors outside HRQoL that contribute to QoL.

WHAT THIS PAPER ADDS:

Quality of life (QoL) and health-related quality of life are distinct concepts rated by young males with Duchenne muscular dystrophy (DMD) and their parents. Factors outside of 'health' contribute to overall QoL in the paediatric population with DMD. This article's abstract has been translated into Spanish and Portuguese.
