OBJECTIVE: To validate the psychometric properties of the Balance Assessment in
Sitting and Standing Positions, including validity (unidimensionality and
concurrent validity), reliability (Rasch reliability), and responsiveness
(compared with the Postural Assessment Scale for Stroke Patients [PASS]) and to
transform the Balance Assessment in Sitting and Standing Positions from an
ordinal-level measure into an interval-level measure. DESIGN: Retrospective
cross-sectional study. SETTING: Medical records from a medical center.
PARTICIPANTS: Patients with stroke (N=1193). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The 4-item Balance Assessment in Sitting and Standing Positions
was used, assessing static sitting balance, dynamic sitting balance, static
standing balance, and dynamic standing balance. RESULTS: Data of 1193 patients
with stroke were included for Rasch analysis.
The 4 items of the Balance
Assessment in Sitting and Standing Positions constituted a unidimensional
construct (infit/outfit mean square, .75-1.05), had good concurrent validity
(r=.70-.90), and had sufficient Rasch reliability (.93). The Balance Assessment
in Sitting and Standing Positions had large responsiveness (effect size, 1.20;
standardized response mean, 1.51) and was comparable with the PASS (effect size,
.90; standardized response mean, 1.32). CONCLUSIONS: The Balance Assessment in
Sitting and Standing Positions has sound psychometric properties. The
transformed-Rasch scores of the Balance Assessment in Sitting and Standing
Positions can be used to identify patients' balance function and detect patients' changes.
