TI  - Psychometric properties of the Minnesota Living with Heart Failure--Brazilian 
      version--in the elderly.
PG  - 997-1005
AB  - BACKGROUND: Heart failure (HF) has implications for the quality of life for any 
      age range, more so for the elderly who simultaneously present other limitations 
      imposed by multiple co-morbidities. Although there are several instruments to 
      measure Health Related Quality of Life (HRQL), none is specific to the elderly 
      with HF. Among disease-specific instruments, Minnesota Living with Heart 
      Failure(LHFQ) has not been studied extensively among the elderly with respect to 
      its psychometric properties. OBJECTIVE: The purpose of this study was to evaluate 
      the convergent, divergent and discriminative validity of the Brazilian version of 
      LHFQ applied to elderly HF patients. METHOD: One hundred and seventy (170) 
      elderly were interviewed. LHFQ capacity to discriminate subjects among New York 
      Heart Association (NYHA) Classes I, II and III/IV was analyzed. Convergent and 
      divergent validity was evaluated through the correlation between the domains of 
      LHFQ and the generic instrument, Medical Outcomes Study (MOS) 36-item Short-Form 
      Health Survey (SF-36). RESULTS: The LHFQ total score and physical dimension 
      sub-scale discriminated between the three sub-groups of NYHA Classes I, II and 
      III/IV (P < .0001). The emotional dimension discriminated NYHA Classes I and 
      III/IV (P = .0034). The physical and emotional dimensions of the LHFQ and SF-36 
      were significantly correlated (coefficients from .46 to .70 for physical 
      dimension and from .31 to .65 for emotional dimension). However, contrary to 
      expectations, the divergent validity was not totally confirmed as there was no 
      difference in the magnitude of the correlations between the LHFQ emotional and 
      physical dimensions and the SF-36 role physical, social functioning and role 
      emotional. Thus, the results suggest that LHFQ seems to be a valid tool to 
      measure HRQL in the elderly, but new studies remain necessary to gain a better 
      understanding of its discriminative validity for more advanced NYHA functional 
      classes and for its divergent validity.
