The International Knee Documentation Committee-Subjective Form (IKDC-SF) is one of the most used measures for evaluating the quality of life among people experiencing knee pain but is not yet available in Hebrew. Similarly, the Tampa Scale for Kinesiophobia (TSK), used to evaluate fear of movement, is not available in Hebrew. This study aimed to determine the reliability and construct validity of the Hebrew IKDC-SF and TSK among people experiencing chronic knee pain.Translation and cultural adaptation of the IKDC-SF and TSK questionnaires, followed by test-retest reliability within a two-week interval. We report on internal consistency, construct validity, and the psychometric properties of both questionnaires.Both questionnaires showed high internal consistency (Cronbach's α = 0.85 and 0.89, respectively) and test-retest reliability, expressed by the Intra-Class Correlation Coefficient (ICC = 0.89 and 0.80 respectively). The standard error of measurement, group smallest real difference and minimal detectable change for the IKDC-SF were 4.66, 9.13, and 12.91 points, and 3.64, 7.13, and 10.08 points for the TSK, respectively.We demonstrated that the Hebrew version of the IKDC-SF and TSK is reliable and valid for assessing QoL, function, and kinesiophobia among people experiencing chronic knee pain. |
