AB  - BACKGROUND: Health-related quality of life (HRQoL) is an important outcome 
      indicator for chronic diseases. This study aimed to develop a new instrument for 
      assessment of HRQoL in chronic heart failure (CHF) and evaluate its psychometric 
      properties. METHODS: This study included two steps of conceptualization and item 
      generation, and assessment of the psychometric properties of an instrument for 
      measuring HRQoL in patients with CHF. A sample of 495 patients with confirmed 
      diagnosis of heart failure participated in the study. In addition to content 
      validity, exploratory and confirmatory factor analyses, concurrent validity, 
      convergent validity, known groups comparison were performed to assess construct 
      validity. Internal consistency, and stability were estimated by the Cronbach's 
      alpha, the MacDonal's Omega, and intraclass correlation coefficients. RESULTS: 
      The content validity of the developed chronic heart failure quality of life 
      questionnaire was assessed by 10 experts. The exploratory factor analysis 
      indicated a four-factor solution for the instrument containing 21 items that 
      jointly accounted for 65.65% of variance observed. The confirmatory factor 
      analysis confirmed the four factor solution with the following fit indexes 
      (chi(2)/df = 2.214, CFI = 0.947, NFI = 0.91, TLI = 0.937, IFI = 0.947, GFI = 0.899, 
      AGFI = 0.869, RMSEA = 0.063). However, at this stage one item was removed. The 
      concurrent and convergent validity of the CHFQOLQ-20 were established using the 
      Short Form Health Survey (SF-36), and the MacNew Heart Disease Quality of Life 
      Questionnaire, respectively. The known-groups validity as assessed by using the 
      New York Heart Association (NYHA) functional classification showed that the 
      questionnaire discriminated well between patients who differed in functional 
      classification. The internal consistency and test-retest reliability of the 
      CHFQOLQ-20 were satisfactory, with a Cronbach's alpha and intraclass correlation 
      coefficient (ICC) values of 0.93 and 0.84, respectively. CONCLUSION: The results 
      confirmed that CHFQOLQ-20 is a valid and reliable instrument for measuring 
      quality of life (QoL) in patients with CHF. It is a short and easy-to-use 
      instrument that is also capable of assessing the cognitive functioning, which has 
      been overlooked in previous questionnaires.
