Adult Camberwell Assessment of Need (CAN)

Adult Camberwell Assessment of Need (CAN) 2nd edition

All versions of the adult CAN measure the ‘need rating’ for each domain. The need rating is either 'Unmet need' (a current serious problem), 'Met need' (no problem because of help given) or 'No need' (not a problem). This need rating has proven useful in working with individuals (for clinical purposes) and for research.
There are four versions of the adult CAN for use in clinical work and in research studies.
The adult CAN is used to understand the health and social needs of adults who have severe mental health problems. It covers 22 domains of an individual's life, such as accommodation, food, self-care, daytime activities, psychotic symptoms, childcare, money, psychological distress, physical health and relationships.

Adult CAN versions 

There are four versions of the adult CAN: CANSAS, CANSAS-P. CAN-R and CAN-C.

Camberwell Assessment of Need Short Appraisal Schedule (CANSAS) 

CANSAS is a one-page version that can be used in routine clinical work or as an outcome measure in research studies. It assesses the need rating for each of the 22 CAN domains. The perspective of staff, service users and informal carers are recorded separately. Information is recorded on CANSAS by staff.

CAN 2nd edition book

The first edition of the adult CAN was developed by a team of collaborators at King's College London in 1994:

Phelan M, Slade M, Thornicroft G, Dunn G, Holloway F, Wykes T, Strathdee G, Loftus L, McCrone P & Hayward P (1995) The Camberwell Assessment of Need: the validity and reliability of an instrument to assess the needs of people with severe mental illness, British Journal of Psychiatry, 167, 589-95.

 

It was published in book form in 1999:

Slade M, Loftus L, Phelan M, Thornicroft G Wykes T (1999) The Camberwell Assessment of Need, London: Gaskell.

 

The CAN 2nd edition book contains complete information about all four adult CAN measures:

Which version of the adult CAN should I use? 

The most useful data to emerge from research using CAN has been the need rating for service user-rated unmet need. Therefore, CANSAS or CANSAS-P will be the most appropriate version for most uses.
