We report on the development of a participation measure for patients
with congestive heart failure (CHF)-the Participation Scale for Patients with CHF
(PS-CHF)-and the determination of its unidimensionality, reliability, and
validity. DESIGN: This study included two rounds of data collections: 62 patients
enrolled in the first round for the purpose of item reduction, and 130 CHF
patients and 96 healthy controls participated in the second round for
questionnaire validation. RESULTS:
The PS-CHF was organized into five items
designed to ask about limitations to participation. The PS-CHF score ranges from
5 points (lowest level of participation) to 20 points (highest level of
participation). On Rasch analysis, the item calibrations ranged from +0.51 logit
for the most difficult item to -0.56 logit for the least difficult item. The
range of mean square statistics values was 1.20-0.81 for infit and 1.34-0.72 for
outfit. The intraclass correlation coefficient between scores from two successive
administrations of the PS-CHF, separated by 2 wks, was 0.94. The total PS-CHF
score in CHF patients was significantly lower than in healthy controls.
CONCLUSIONS: The PS-CHF was developed to determine a disease-specific
participation measure for patients with CHF. The PS-CHF may serve as a clinically
meaningful outcome measure for CHF patients.
