Test-retest repeatability for Fatigue Assessment Scale, Short-Form 6-Dimension and King's Sarcoidosis Questionnaire in people with sarcoidosis associated fatigue.

Background And Aim: Patient related outcomes are important in sarcoidosis but the medium-term repeatability of the key patient reported outcome measure is not known. We aimed to test the repeatability of the Fatigue Assessment Scale (FAS), Short Form 6-Dimension (SF-6D), and King's Sarcoidosis Questionnaire (KSQ) in free living people with sarcoidosis associated fatigue.

Methods: Twelve people with sarcoidosis associated fatigue completed the FAS, short form 36 questionnaire (SF-36) and the KSQ at baseline and 12 weeks.
