Description
Summary:People with learning disabilities and mental health problems have complex needs. Care should be provided according to need. To develop a standardised needs-assessment instrument for adults with learning disabilities and mental health problems. The Camberwell Assessment of Need for Adults with Developmental and Intellectual Disabilities (CANDID) was developed by modifying the Camberwell Assessment of Need (CAN). Concurrent validity was tested using the Global Assessment of Functioning (GAF) and the Disability Assessment Schedule (DAS). Test-retest and interrater reliability were investigated using 40 adults with learning disabilities and mental health problems. CANDID scores were significantly correlated with both DAS (P < 0.05) and GAF scores (P < 0.01). Correlation coefficients for interrater reliability were 0.93 (user), 0.90 (career), and 0.97 (staff ratings); for test-retest reliability they were 0.71, 0.69 and 0.86 respectively. Mean interview duration was less than 30 minutes. The CANDID is a brief, valid and reliable needs assessment instrument for adults with learning disabilities and mental health problems.
