AB  - BACKGROUND: Rehabilitation interventions promote functional recovery among frail 
      older adults and little is known about the clinical significance of physical 
      outcome measure changes. The purpose of our study is to examine the minimal 
      clinically important difference (MCID) for the 6-minute walk distance (6MWD) 
      among frail Asian older adults. METHODS: Data from the "Evaluation of the Frails' 
      Fall Efficacy by Comparing Treatments" study were analyzed. Distribution-based 
      and anchor-based methods were used to estimate the MCID of the 6MWD. Participants 
      who completed the trial rated their perceived change of overall health on the 
      Global Rating of Change (GROC) scale. The receiver operating characteristic curve 
      (ROC) was used to analyze the sensitivity and specificity of the cut-off values 
      of 6MWD (in meters) for GROC rating of "a little bit better" (+2), based on 
      feedback from participants. RESULTS: The mean (SD) change in 6MWD was 37.3(46.2) 
      m among those who perceived a change (GROC >/= 2), while those who did not was 
      9.3(18.2) m post-intervention (P = 0.011). From the anchor-based method, the MCID 
      value for the 6MWD was 17.8 m (sensitivity 56.7% and specificity 83.3%) while 
      distribution-based method estimated 12.9 m. CONCLUSION: The MCID estimate for 
      6MWD was 17.8 m in the moderately frail Asian older adults with a fear of 
      falling. The results will aid the clinicians in goal setting for this patient 
      population.
