AB  - This study used the standard error of measurement (SEM) to evaluate 
      intra-individual change on both the Chronic Respiratory Disease Questionnaire 
      (CRQ) and the SF-36. After analyzing the reliability and validity of both 
      instruments at baseline among 471 COPD outpatients, the SEM was compared to 
      established minimal clinically important difference (MCID) standards for three 
      CRQ dimensions. A value of one SEM closely approximated the MCID standards for 
      all CRQ dimensions. This SEM-based criterion was then validated by 
      cross-classifying the change status (improved, stable, or declined) of 393 
      follow-up outpatients using the one-SEM criterion and the MCID standard. 
      Excellent agreement was achieved for all three CRQ dimensions. Although MCID 
      standards have not been established for the SF-36, the one-SEM criterion was 
      explored in these change scores. Among SF-36 scales demonstrating acceptable 
      reliability and reasonable variance, the percent of individuals within each 
      change category was consistent with those seen in the CRQ dimensions. These 
      results replicate previous findings where a value of one SEM also closely 
      approximated MCIDs for all dimensions of the Chronic Heart Disease Questionnaire 
      among cardiovascular outpatients. The one-SEM criterion should be explored in 
      other health-related quality of life instruments with established MCIDs.
