Using the adult Camberwell Assessment of Need (CAN) for research
I am not sure whether the adult CAN is suitable for my research. Can I have a sample copy?
You can download all four adult CAN versions from the main adult CAN page to help you decide whether to use CAN in your research. The CAN 2nd edition book contains detailed information about the theory base and empirical evidence for using CAN, along with detailed information on each measure, so it is recommended that the adult CAN 2nd edition book be obtained as a resource when using the CAN for research.
CAN-R or CANSAS? What’s the difference and which one should we use in our research study?
The CANSAS is a one-page assessment, and identifies only the need rating for each of the 22 CAN domains. CAN-R is a 22-page assessment, and records more information about each of the 22 domains. The most useful data to emerge from research using the adult CAN have been the level of Met and Unmet need, and the extra information assessed by the CAN-R has proved more difficult to interpret. Therefore, the CANSAS will be the most appropriate version for most research uses.
Can other domains be added?
In developing the adult CAN, the challenge was to create an assessment that was comprehensive yet still as short as possible. Some domains that are important, such as spiritual problems and sleep, were therefore, after careful consideration, not included. Other domains can be added for research purposes, but these should be added on to the existing 22 domains. The psychometric properties of any extra domains will, of course, need to be established. Please note, any publication presenting CAN data should clearly separate data about the 22 CAN domains from data about any extra domains.
How should the adult CAN be used as an outcome measure?
Three summary variables are of most interest – total number of needs (i.e. Met + Unmet needs), total number of Met needs, and total number of Unmet needs (maximum 22 for each).
Patient-rated Unmet need has emerged as the most informative CAN score, as described in the adult CAN 2nd edition book.
Is staff and service user agreement on need ratings a measure of reliability?
No. Staff and service users assess needs differently, and this difference is not due to measurement error.
Has a system been developed for scanning adult CAN data?
Is there an electronic version of the adult CAN for research use?
Is it possible to include the adult CAN in a publication I am compiling?
