To investigate the psychometric properties of a cardiovascular extension of an existing utility-based quality of life questionnaire (Health Measurement Questionnaire).
The new instrument has been named the Utility Based Quality of life-Heart questionnaire, or UBQ-H.
Design-Explored the test-retest reliability, construct validity, and responsiveness of the UBQ-H.
Patients-A sample of 322 patients attending cardiac outpatient clinics were recruited from two large metropolitan teaching hospitals.
A second sample of 1112 patients taking part in the LIPID trial was also used to investigate the validity and responsiveness of the UBQ-H.
Ninety per cent of all UBQ-H questionnaires were returned, and item completion rates were high (median of less than 1% missing or N/A answers).
Cronbach's a measure of internal consistency for the scales ranged between 0.79-0.91, and each item was also most strongly correlated with its hypothesised domain than alternative domains.
The intra-class test-retest reliability of the UBQ-H scales ranged from 0.65 to 0.81 for patients with stable health.
Results supported the construct validity of the UBQ-H.
The UBQ-H was significantly correlated with other information on quality of life (for example, General Health Questionnaire) as anticipated. (...)
