Eligibility Criteria
Inclusion Criteria
- •Eligible participants must meet the knee and hip osteoarthritis (OA) diagnostic criteria according to the American College of Rheumatology (ACR).
Exclusion Criteria
- •rheumatoid arthritis
- •serious pathological conditions (inflammatory arthritis and malignancy)
- •total or partial arthroplasty of the affected joint
- •individuals who cannot read and understand documents written in the Arabic language.
Outcomes
Primary Outcomes
Content Validity
Time Frame: 1 day
Assessed using the Content Validity Index (CVI) with an acceptable value of at least 0.8.
Test-retest Reliability
Time Frame: 48-72 hours
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.
Construct Validity
Time Frame: 1 day
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.
Internal Consistency
Time Frame: 48-72 hours
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.
Secondary Outcomes
