OBJECTIVE: To compare the responsiveness and predictive validity of the Balance
Computerized Adaptive Test (Balance CAT) and the Postural Assessment Scale for
Stroke patients (PASS) in inpatients with stroke receiving rehabilitation.
DESIGN: A pre-post test design. SUBJECTS: Eighty-five inpatients after stroke.
METHODS: Effect size d and Wilcoxon signed-rank test were used to assess the
internal responsiveness of the Balance CAT and PASS. The changes in the Barthel
Index (BI) and the mobility subscale of the Stroke Rehabilitation Assessment of
Movement (MO-STREAM) scores were both chosen as the external criteria for
examining external responsiveness. Moreover, to investigate the predictive
validity, the admission scores of the two balance measures, and the discharge
score of the BI/MO-STREAM, were examined by simple linear regression analysis.
RESULTS: Both the Balance CAT and PASS had high internal responsiveness (effect
size d >/= 0.87) and fair external responsiveness (r(2) >/= 0.20). The predictive
validities of both measures were sufficient (r(2) >/= 0.33). The Balance CAT took
approximately 3 items (min-max = 2-4) to complete. CONCLUSION: The Balance CAT
and PASS have sufficient responsiveness and predictive validity in inpatients
with stroke receiving rehabilitation. The Balance CAT is more efficient to
administer and is thus recommended over the PASS.
