Reliability was tested by analysis of stability, equivalence, and internal consistency by calculating Cronbach’s Alpha and Intraclass Correlation Coefficient (ICC). Results Five translators, eight judges, and 14 possible users in the pre-test participated in the first stage. The agreement rate was 80% in all domains and was >90% for the total score. Fifteen days after the first assessment, 20 of these participants were randomly selected for reassessment. The ICC values for stability and equivalence were 82.5% (p=0.008) and 95.4% (p |
