Abstract:

Objective To investigate the reliability and validity of the assessment tools of Brief ICF Core Sets for Arthroplasty of Knee Osteoarthritis in Perioperative Period (ICSAKOPP).
Methods From May, 2022 to April, 2023, 320 patients undergoing knee arthroplasty were selected in Peking University Third Hospital, China-Japan Friendship Hospital, Peking University First Hospital and Chinese PLA General Hospital. Trained assessors used Brief ICSAKOPP to evaluate all enrolled patients before arthroplasty, three days (±one day) after arthroplasty, three weeks (±one week) after arthroplasty, and three months (±one month) after arthroplasty. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were recorded at the same time. Five professionals were asked to score all the items of Brief ICSAKOPP, and the content validity index (CVI) was caculated.
Results A total of 64 cases were dropped down. CVI of all the items of the Brief ICSAKOPP were above 0.8, with a average CVI of the scale of 0.938. The Cronbach's α coefficient of the Brief ICSAKOPP was 0.813. There was a moderate correlation (r = 0.681, P < 0.001) between the overall Brief ICSAKOPP and WOMAC scores, as well as body functional dimension score (r = 0.668, P < 0.001) and activities and participation dimension score (r = 0.657, P < 0.001).
Conclusion Brief ICSAKOPP is good in content validity, internal consistency reliability and criterion validity.
