AB  - OBJECTIVE: The aim of this study was to investigate the psychometric properties 
      of the shortened version of the Functional Difficulties Questionnaire (FDQ). 
      DESIGN: This is a multisite observational study. SETTING: The study was conducted 
      in four tertiary care hospitals in Australia. SUBJECTS: A total of 225 
      participants, following cardiac surgery, were involved in the study. 
      INTERVENTION: Participants completed the original 13-item FDQ and other measures 
      of physical function, pain and health-related quality of life. METHOD: Item 
      reduction was utilized to develop the shortened version. Reliability was 
      evaluated using intraclass correlation coefficients (ICCs), the smallest 
      detectable change and Bland-Altman plots. The validity and responsiveness were 
      evaluated using correlation. Anchor and distribution-based calculation was used 
      to calculate the minimal clinical important difference (MCID). RESULTS: Item 
      reduction resulted in the creation of a 10-item shortened version of the 
      questionnaire (FDQ-s). Within the cohort of cardiac surgery patient, the mean 
      (SD) for the FDQ-s was 38.7 (19.61) at baseline; 15.5 (14.01) at four weeks and 
      7.9 (12.01) at three months. Validity: excellent internal consistency (Cronbach's 
      alpha > 0.90) and fair-to-excellent construct validity (>0.4). Reliability: internal 
      consistency was excellent (Cronbach's alpha > 0.8). The FDQ-s had excellent 
      test-retest reliability (ICC = 0.89-0.92). Strong responsiveness overtime was 
      demonstrated with large effect sizes (Cohen's d > 1.0). The MCID of the FDQ-s was 
      calculated between 4 and 10 out of 100 (in cm). CONCLUSION: The FDQ-s 
      demonstrated robust psychometric properties as a measurement tool of physical 
      function of the thoracic region following cardiac surgery.
