简要总结
The King's Sarcoidosis Questionnaire (KSQ) is a brief questionnaire assessing health status in patients with sarcoidosis. The KSQ was previously validated in English German and Dutch.
KSQ will be translated into Danish and validated in a Danish sarcoidosis population.
详细描述
KSQ will be linguistic validated according to existing guidelines. Consecutive patients with sarcoidosis will complete KSQ and other health questionnaires at baseline, after two weeks and 12 months. Concurrent validity, reliability, and responsiveness will be assessed.

结局指标
主要结局
Internal consistency
时间窗: At baseline
Internal consistency, the interrelatedness of the items in the questionnaire, will be estimated by calculating Cronbach's α for each domain.
Responsiveness
时间窗: 1 year from baseline
Responsiveness: The ability to detect changes over time was assessed by measuring changes in KSQ over 12 months and correlating to changes in other questionnaires
Test-retest reliability
时间窗: At baseline
Test-retest reliability will be evaluated by Intraclass correlation coefficients (ICC) and Bland- Altman plots comparing KSQ scores at baseline and at 14 days in stable patients
Concurrent validity
时间窗: At baseline
Concurrent validity was assessed by measuring the correlation of KSQ to other questionnaires
