OBJECTIVE: To determine the psychometric properties of 2 neglect measures, the
Behavioral Inattention Test (BIT)-conventional and the Catherine Bergego Scale
(CBS), in acute spatial neglect. Spatial neglect is a failure or slowness to
respond, orient, or initiate action toward contralesional stimuli, associated
with functional disability that impedes stroke recovery.
Early identification of
specific neglect deficits may identify patients likely to experience chronic
disability. However, psychometric evaluation of assessments has focused on
subacute/chronic populations. DESIGN: Correlational/psychometric study. SETTING:
Inpatient rehabilitation hospital. PARTICIPANTS: Screening identified 51
consecutive patients with a right-hemisphere stroke with left neglect (BIT score
<129 or CBS score >11) tested an average of 22.3 days poststroke. INTERVENTIONS:
Not applicable. MAIN OUTCOME MEASURES: We obtained BIT, CBS, and Barthel Index
assessments for each participant and clinical and laboratory measures of
perceptual-attentional and motor-intentional deficits. RESULTS: The BIT showed
good reliability and loaded onto a single factor. Consistent with our theoretical
prediction, principal components analysis of the CBS identified 2 underlying
factors: Where perceptual-attentional items (CBS-PA) and embodied,
motor-exploratory items (CBS-ME). The CBS-ME uniquely predicted deficits in
activities of daily living (ADLs) assessed by using the Barthel Index, but did
not predict clinical and laboratory assessments of motor-intentional bias. More
severe neglect on the CBS-PA correlated with greater Where perceptual-attentional
bias on clinical and laboratory tests, but did not uniquely predict deficits in
ADLs. CONCLUSIONS: Our results indicate that assessments of spatial neglect may
be used to detect specific motor-exploratory deficits in spatial neglect.
Obtaining CBS-ME scores routinely might improve the detection of acute-stage
patients with spatial action deficits requiring increased assistance that may
persist to the chronic stage.
