结局指标
主要结局
Floor and ceiling effect
时间窗: 1 day
It will be considered present if more than 15% of the sample score the lowest or highest possible total score, respectively
Content Validity
时间窗: 1 day
Assessed using the Content Validity Index (CVI) with an acceptable value of at least 0.8.
Internal Consistency
时间窗: 3-7 days
Assessed by calculating the Cronbach's alpha (α) and the corrected item-total correlation. A Cronbach's α value of ≥0.7, and a corrected item-total correlation, measured using the Pearson correlation coefficient, of ≥0.3 will be considered acceptable.
Test-retest Reliability
时间窗: 3-7 days
Assessed by calculating the intraclass correlation coefficient (ICC) between the EARS-Ar scores of the first two test sessions. An ICC value of \>0.8 and 0.6-0.8 will be considered as excellent and good correlation, respectively.
Construct Validity
时间窗: 1 day
Assessed by calculating the Spearman's correlation coefficient (ρ) between the Exercise Adherence Rating Scale-Arabic version (EARS-Ar) score and the Fear Avoidance Belief Questionnaire (FABQ), the Numeric Pain Rating Scale (NPRS), the Roland-Morris Disability Questionnaire (RMDQ), and the Knee Injury and osteoarthritis Outcome Score (KOOS) measurement tools. The coefficient is classified as follows: ρ = 0.3-0.7 moderate correlation, and \>0.7 strong correlation.
