What is the MCID for the AKPS?

• A. 4-6
• B. 6-8
• C. 8-10
• D. 10-12

Answer: (C)

The smallest change on the AKPS that patients are likely to perceive as meaningful is about 8–10 points. The AKPS is a 0–100 patient-reported scale where higher scores mean less pain and better function. MCID stands for the minimal change that patients notice and that would influence clinical decisions. Across studies that link changes in AKPS to patient-perceived improvement, the threshold that consistently marks a truly noticeable, meaningful difference falls in the 8–10 point range. So, when a patient improves by roughly 8–10 points, that change is likely to be clinically important, not just a minor fluctuation or measurement noise. Values can vary with specific patient groups or contexts, but 8–10 points is the most supported range for the AKPS.
