Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Floor and ceiling effect | It will be considered present if more than 15% of the sample score the lowest or highest possible total score, respectively | 1 day | |
Primary | Content Validity | Assessed using the Content Validity Index (CVI) with an acceptable value of at least 0.8. | 1 day | |
Primary | Construct Validity | Assessed by calculating the Spearman's correlation coefficient (?) 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: ? = 0.3-0.7 moderate correlation, and >0.7 strong correlation. | 1 day | |
Primary | Internal Consistency | Assessed by calculating the Cronbach's alpha (a) and the corrected item-total correlation. A Cronbach's a value of =0.7, and a corrected item-total correlation, measured using the Pearson correlation coefficient, of =0.3 will be considered acceptable. | 3-7 days | |
Primary | Test-retest Reliability | 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. | 3-7 days | |
Secondary | Responsiveness | Participating patients will be categorized according to their reported Global Rating of Change (GRoC) scores (external anchor) to either improved (GRoC=3) or stable group (GRoC<3 to >-3) and a between-group comparison will be performed using an unpaired t-test. | 3 weeks |
