AB  - BACKGROUND: The minimal clinically important difference (MCID) is the smallest 
      change in patient-derived scores that is clinically important. We sought to 
      validate the MCID of the modified activities assessment scale (mAAS). METHODS: 
      Patients were surveyed prior to undergoing abdomen/pelvis CT scans and resurveyed 
      one year later. Before resurvey, patients were asked if they had no change, 
      worsening, or improvement in AW-QOL. The anchor-based MCID was calculated by 
      taking a weighted mean of the difference between control (no change) and study 
      (worsening/improved) groups. Distribution-based approach was calculated by 
      one-half of the standard deviation in the QOL change. RESULTS: 52.8% of 181 
      patients self-reported no change, 39.2% reported improvement, and 8.3% reported 
      worsening AW-QOL. The anchor-based approach MCID was 4. The distribution-based 
      MCID was 16. CONCLUSION: Our study results validate prior work demonstrating 
      similar ranges of the mAAS MCID. We recommend adopting an MCID of 5 and 15 for 
      AW-QOL with mAAS.
