Kansas City Cardiomyopathy Questionnaire Administered to Hospitalized Patients With Heart Failure.

BACKGROUND AND PURPOSE: 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). METHODS: Confirmatory factor analysis, Cronbach's alphas, and correlations were performed to examine the scale's dimensions, reliability, and validity. RESULTS: 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. CONCLUSIONS: The psychometric properties of the KCCQ may be different based on the population in which the KCCQ is administered, which may have clinical implications.
