TI  - Discriminant properties of commonly used quality of life measures in heart 
      failure.
PG  - 349-59
AB  - Health-related quality of life (HRQL) instruments have been used to measure HRQL 
      in heart failure patients, but how different instruments compare in the same 
      groups of patients is not known. The purpose of this study was to compare the 
      reliability and validity of three HRQL measures in 211 heart failure patients 
      recruited from clinics affiliated with an urban hospital. Two disease-specific 
      instruments, the chronic heart failure questionnaire (CHQ) and the living with 
      heart failure questionnaire (LHFQ), and one generic instrument, the short-form 12 
      (SF-12), were administered. Patients reported moderate to low HRQL scores. Floor 
      or ceiling effects were noted in the disease-specific instruments. Internal 
      consistency reliabilities of the CHQ and LHFQ were satisfactory. Construct, 
      convergent, and discriminant validity were supported for each instrument. Each 
      scale and subscale, except for the SF-12 mental component scale, differentiated 
      between patients with New York Heart Association (NYHA) class I, II, and III plus 
      IV; the LHFQ physical subscale was the only measure to differentiate between 
      patients with NYHA class III and IV. All three instruments were satisfactory for 
      measuring HRQL, but the disease-specific instruments were preferable to the 
      generic instrument. The decision of which instrument to use depends on the 
      purpose of the study.
