Responsiveness and construct validity of EPIC-26, AQoL-6D and SF-6D following treatment in prostate cancer.

ABSTRACT:

Purpose

To assess construct validity and responsiveness of the Expanded Prostate Cancer Index Composite Instrument (EPIC-26) relative to the Short-Form Six-Dimension (SF-6D) and Assessment of Quality of Life 6-Dimension (AQoL-6D) in patients following treatment for prostate cancer.

Methods

Retrospective prostate cancer registry data were used. The SF-6D, AQoL-6D, and EPIC-26 were collected at baseline and one year post treatment. Analyses were based on Spearman's correlation coefficient, Bland-Altman plots and intra-class correlation coefficient, Kruskal Wallis, and Effect Size and the Standardised Response Mean for responsiveness.

Results

The study sample was comprised of 1915 patients. Complete case analysis of 3,697 observations showed moderate evidence of converge
