Internal consistency for the entire scale is good at .88 for both
client or family samples (Sherer et al, 1998a). Factor analysis
(Sherer et al, 1998a) revealed three factors: cognitive, behavioral/affective,
and motor/sensory functioning. Internal consistencies for the factors
are adequate, given the small numbers of items, ranging from .68
to .80 for the client sample and .57 to .80 for the family sample.
Test-retest reliability has not been reported.
The Awareness Questionnaire was shown to be sensitive to differences
in client, family/significant other, and clinician ratings with
the expected finding that persons with TBI rate themselves as less
impaired than do family members or clinicians (Sherer et al, 1998c).
In the same study, client vs. family/significant other differences
demonstrated the expected pattern of greater impaired self-awareness
of cognitive and behavioral/affective functioning as compared to
validity has been demonstrated as client vs. family/significant
other differences and the direct clinician rating of accuracy of
self-awareness have been shown to be predictive of eventual productivity
outcome for persons with TBI (Sherer et al, 1998b). These two measures
accounted for 31% of variance in productivity outcome in a sample
of 66 persons with TBI.
