OBJECTIVE: To investigate the validity and responsiveness of the Care and Needs
Scale (CANS), which was designed to assess support needs of people with traumatic
brain injury (TBI). DESIGN: Two samples of community clients (n=38, n=30) were
recruited to examine concurrent, convergent/divergent, and discriminant validity.
The ability of the CANS to detect change over a 6-month period from the time of
inpatient rehabilitation discharge (predictive validity and responsiveness) was
investigated in a third sample of 40 rehabilitation inpatients. SETTING: Two
Brain Injury Rehabilitation Units in Sydney, Australia. PARTICIPANTS: People
(N=108) aged between 16 and 70 years admitted for rehabilitation after TBI.
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The CANS, Supervision
Rating Scale, FIM, Sydney Psychosocial Reintegration Scale, and Disability Rating
Scale. RESULTS: Evidence for concurrent validity was shown with fair to moderate
correlation coefficients between the CANS and measures of supervision, functional
independence, and psychosocial functioning (absolute value, r(s)=.43-.68; P<.01).
Support for convergent and divergent validity was provided by correlation
coefficients that were higher for measures tapping similar constructs (absolute
value, r(s)=46; P<.01) but lower for measures of dissimilar constructs (absolute
value, r(s)=.07-.26; not significant). In addition, the CANS discriminated
between levels of injury severity, functional independence, and overall
functioning (P<.01). In terms of predictive validity and responsiveness, CANS
scores at inpatient rehabilitation discharge predicted the participant's
functioning 6 months later. CONCLUSIONS: These results show the CANS is a valid
and responsive tool and, together with its previously shown reliability, is
suitable for routine application in clinical and research practice.
