TI  - Testing the psychometric properties of the Minnesota Living with Heart Failure 
      questionnaire.
PG  - 265-72
AB  - BACKGROUND: Health-related quality of life (HRQOL) is an important outcome in 
      patients with heart failure. One of the most commonly used instruments to measure 
      HRQOL in this population is the Minnesota Living With Heart Failure Questionnaire 
      (LHFQ). Although the psychometric properties of the LHFQ have been tested, the 
      results do not definitively support the psychometric soundness of the instrument. 
      OBJECTIVE: To examine the psychometric properties of the LHFQ. METHOD: Data from 
      638 patients with heart failure were used to assess the reliability, homogeneity, 
      representativeness, discriminative ability, and construct validity of the LHFQ 
      before and after deletion of 5 items that showed lack of representativeness and 
      contributed to inadequate factor structure. RESULTS: Cronbach's alphas for the 
      LHFQ Total and subscales were greater than .80. Interitem correlation 
      coefficients in 17 of the 21 items, item-total correlation coefficients in 20 
      items, and discriminative ability in all items were acceptable. The total and 
      both subscales of the LHFQ differentiated New York Heart Association functional 
      groups. The Physical subscale was moderately related to the physical measures 
      (the Specific Activity Scale and symptom status), whereas the emotional subscale 
      was weakly related to the measures. The results of item p level testing and 
      factor analysis demonstrated that 7 items were consistently problematic and 5 
      items were recommended to be deleted. The results of the reliability, 
      homogeneity, and construct validity after deletion of these items demonstrated 
      that the psychometric properties of the LHFQ were improved as a result. 
      DISCUSSION: The initial results provided additional support for the reliability 
      and substantial evidence for the validity of the LHFQ. However, the results of 
      item and factor analyses did not fully support the psychometric soundness of 
      several items. The psychometric properties of the LHFQ after deleting these items 
      were improved. These results could provide researchers and clinicians a more 
      useful measure of HRQOL.
