Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Internal consistency | At baseline | Internal consistency, the interrelatedness of the items in the questionnaire, will be estimated by calculating Cronbach's α for each domain. |
| Test-retest reliability | 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 | At baseline | Concurrent validity was assessed by measuring the correlation of KSQ to other questionnaires |
| Responsiveness | 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 |
