title: Kansas City Cardiomyopathy Questionnaire Administered to Hospitalized Patients With Heart Failure.
abstract: The psychometric properties of the Kansas City Cardiomyopathy Questionnaire (KCCQ) have been examined primarily in community-dwelling patients with heart failure (HF). The objective of this research was to examine the properties of the KCCQ administered to patients hospitalized with HF (N = 233).
  
  
  
  Confirmatory factor analysis, Cronbach's alphas, and correlations were performed to examine the scale's dimensions, reliability, and validity.
  
  
  
  Confirmatory factor analysis indicated a 5-factor solution (63.6% of the variance). The Cronbach's alpha levels were greater than .70, except for the self-efficacy dimension (.60). Convergent validity was not verified between the KCCQ and several illness severity measures.
  
  
  
  The psychometric properties of the KCCQ may be different based on the population in which the KCCQ is administered, which may have clinical implications.
