Abstract

Objectives: Validation of quality of life (QoL) instruments assesses the degree to which they measure what they are supposed to measure. Despite most validation exercises being based on statistical tests of difference/association, other alternative validation techniques including exploratory (EFA) and confirmatory factor analysis (CFA) have been proposed. Little is however known about whether validation using EFA/CFA alone is sufficient and/or whether EFA/CFA validation results are comparable to those of other statistical tests. This issue is addressed within the context of validating the Women’s Health Questionnaire (WHQ-23) against the EuroQoL 5 Dimensions 5 Level (EQ-5D-5L) and the Short Form 6 Dimensions (SF-6D).
