Abstract
Objectives
To examine the validity of a modified standard gamble (Mod SG) (nondeath baseline)
by comparing these scores to SG (death baseline), time trade off (TTO), visual analog
scale (VAS), Health Utilities Index (HUI), and Child Health Questionnaire (CHQ).
Method
Respondents were parents of in-patients with cancer receiving chemotherapy and parents
of children without cancer attending outpatient clinics. Construct validity was determined
by comparing a priori hypotheses to actual correlations between measures. Discriminant validity was examined
by anticipating that in-patients with cancer would have lower HRQL than outpatients.
Results
85 families were included. Both Mod SG and SG were moderately correlated with TTO
(r = 0.50 and r = 0.49; P<.01 for both). Both Mod SG and SG were moderately correlated with TTO (r = 0.47 and r = 0.05, P<0.002 for both).
Conclusion
The Mod SG did not perform better than SG. Two nonoverlapping groups of HRQL measures
were demonstrated.
