Brief summary
A study to translate and cross-culturally adapt the Intermittent and Constant Osteoarthritis Pain (ICOAP) measurement tool into the Arabic language, and assess its psychometric properties.
Interventions
Participants shall fill the ICOAP-Ar questionnaire three times within one month in addition to other questionnaires including the KOOS/HOOS, and the Global Rating of Change Scale (GRoC). The first two times will be within a time frame of 48-72 hours. The third time will be after one month.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Content Validity | 1 day | Assessed using the Content Validity Index (CVI) with an acceptable value of at least 0.8. |
| Construct Validity | 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 | 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. |
| Test-retest Reliability | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Responsiveness | 4 weeks | 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. |
