Objective:
To develop a set of 3 hierarchical balance short forms (HBSF; containing sitting, standing, and stepping forms) to measure balance function in patients with stroke.
Design:
First, we developed the HBSF, based on a previous data set, with each short form containing 6 items. Second, we examined the psychometric properties and efficiency of the HBSF.
Setting:
Six teaching hospitals.
Participants:
Patients with stroke (n=764) for the first part of this study; inpatients and outpatients (n=85) for the second part of this study.
Interventions:
Not applicable.
Main Outcome Measures:
We used the item bank (9 sitting-related, 14 standing-related, and 13 stepping-related items) from the Balance Computerized Adaptive Test to develop the HBSF. Both the HBSF and the Berg Balance Scale (BBS) were administered to patients, to determine the concurrent validity and time needed for administration of both measures. Each patient was assessed by 1 of the 3 short forms selected by a rater.
Results:
The reliability of the HBSF was relatively high (reliability coefficients, .94-.95). The scores of the HBSF were highly correlated with those of the BBS (Spearman ρ=.80-.91), supporting the concurrent validity of the HBSF. The average time needed to administer the HBSF was 122 seconds (ie, about 40% of that for the BBS).
Conclusions:
Our results provide sufficient evidence that the HBSF is an efficient, reliable, valid, and practical way to measure balance function in patients with stroke.
