The validity of quality of life Questionnaires in capturing people’s experience of living with asthma

Student thesis: Doctoral Thesis


At least six asthma-specific measures of health-related quality of life (HrQoL) exist. It is unclear what concepts of “quality of life” these instruments assess, how they compare psychometrically and what patients think of them. A structured review of six of these questionnaires found that they differ in almost all criteria considered (conceptual model, reliability, validity, interpretability, patient burden, translations). A mini version of the Juniper Asthma Quality of Life Questionnaire (Mini AQLQ-J) and the Sydney Asthma Quality of Life Questionnaire (AQLQ-S) were psychometrically analysed, using data from an adult asthma trial (n=146). Strong correlations with asthma symptoms and asthma control suggest that the measures may not measure a distinct quality of life construct.
