Table 17.9 Characteristics of the Community Balance and Mobility Scale
Reliability |
Test-Retest: ICC=0.975 (Inness et al. 1999; TBI) Internal Consistency: α=0.96 (Inness et al. 1999; TBI) |
Validity |
Face Validity: Items rated as relevant to the assessment of balance by PT’s (Inness et al. 1999; TBI). Construct Validity: Correlated with gait variables: walking velocity (r=0.69), step length (r=0.75) and step time variability (r=-0.49). However, CBMS scores did not correlate significantly with measures of postural sway or with a measure of balance confidence (ABC). |
Responsiveness | SRM=1.26 (for CBMS change scores; Inness et al. 2011) |
Tested for ABI/TBI patients? | Developed for use in TBI population. |
