Development and Validation of an Abbreviated Version of the Expanded Prostate Cancer Index Composite Instrument (EPIC-26) for Measuring Health-Related Quality of Life Among Prostate Cancer Survivors

摘要

ObjectivesWidespread implementation of HRQOL measurement in prostate cancer practice and research requires concise instruments. Having 50 questions, the full-length Expanded Prostate cancer Index Composite (EPIC) is cumbersome to administer outside of studies focusing exclusively on HRQOL. To facilitate HRQOL measurement in a broad range of prostate cancer research and practice settings, we developed and validated an abbreviated version of EPIC.
