Outcomes

Primary Outcomes

Content Validity

Assessed using the Content Validity Index (CVI) with an acceptable value of at least 0.8.

Time frame: 1 day

Construct Validity

Assessed by calculating the Spearman's correlation coefficient (ρ) between the Arabic ICOAP (ICOAP-Ar) score and the relevant pain and symptoms score of the Knee Injury and Osteoarthritis Outcome Score (KOOS) and Hip Injury and Osteoarthritis Outcome Score (HOOS) measurement tools. The coefficient is classified as follows: ρ = 0.3-0.7 moderate correlation, and \>0.7 strong correlation.

Time frame: 1 day

Internal Consistency

Assessed by calculating the Cronbach's alpha (α) and the corrected item-total correlation. A Cronbach's α value of ≥0.7, and corrected item-total correlation, measured using the Pearson correlation coefficient, of ≥0.3 will be considered acceptable.

Time frame: 48-72 hours

Test-retest Reliability

Assessed by calculating the intraclass correlation coefficient (ICC) between the ICOAP-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.

Time frame: 48-72 hours

Secondary Outcomes

Responsiveness

Participants will be categorized according to their reported Global Rating of Change (GRoC) Scale scores to either improved (GRoC ≥3) or stable group (GRoC \<3 to \>-3) and between-group comparison of each group's ICOAP-Ar scores will be performed using unpaired t-test.

Time frame: 4 weeks
