Feasibility and reliability of the elderly version of the Camberwell Assessment of Needs (CANE): results from the São Paulo Ageing & Health Study

Abstract

OBJECTIVE: We set out to assess the feasibility, reliability and convergent validity of the Camberwell Assessment of Needs for the Elderly Scale in older residents of a Brazilian urban elderly population of low socioeconomic status. METHOD: We identified 32 older users of community health services from a population-based catchment area survey. We administered the Brazilian version of the Camberwell Assessment of Needs for the Elderly Scale to the older person and to an informal caregiver, and tape-recorded the assessments. Interviewers made a rating. Tape-recordings were independently co-rated. RESULTS: Items contributing to older person and caregiver reports of needs and unmet needs had a high internal consistency. Inter-rater reliability was excellent for all needs, and fair to good for unmet needs. Older person and caregiver's reports, and interviewer ratings were highly mutually consistent. Convergent validity was supported by associations, as hypothesized, between needs and disability, and needs and dementia. CONCLUSIONS: The Brazilian version of the Camberwell Assessment of Needs for the Elderly Scale is a feasible, reliable and, to the extent assessed, valid assessment of unmet needs in a disadvantaged low and middle income countries setting. Its practical utility as a clinical tool remains to be assessed.
