The CAN is now the most widely used needs assessment measure in mental health systems internationally. For example, in relation to psychosis, it is the most widely cited measure in first-episode psychosis studies, and a review of patient-reported outcomes in schizophrenia concluded that ‘the most commonly used measures are the Camberwell Assessment of Need and the Camberwell Assessment of Need Short Appraisal Schedule’ (p. 22). It is also used to assess needs in diverse mental health groups (e.g. psychosis, bipolar disorder, common mental disorders) with other clinical (e.g. neurology, HIV) and non-clinical (e.g. sex trafficking, asylum seekers, non-clinical voice hearers) populations, and to compare the needs of different populations, such as people with and without intellectual disabilities in mental health case management services.
