Background And Purpose:
The Kansas City Cardiomyopathy Questionnaire (KCCQ) was adapted to be administered to the family caregiver/significant other (FC/SO) of hospitalized patients with heart failure (HF). The objective was to examine the psychometrics of the adapted scale (KCCQ-SO).
Methods:
Factor analysis, Cronbach's alpha, and correlations were used.
Results:
A 5-factor solution was found that explained 67.9% of the variance. The internal consistency of the KCCQ-SO factors were all greater than .70. Patient and FC/SO perceived health status scores were significantly related.
Conclusions:
Because the scores were found to have high internal consistency and correlated with patient scores on the KCCQ, there is evidence that the FC/SOs' reports may be used in circumstances when the patient is unable or unwilling to answer questions.
