Moss-PAS (Check) is a 25-item questionnaire, written in everyday language, for use primarily by care staff and families who are best placed to notice changes in the behaviour of the people they support. It is designed to record the presence of a range of problems, all of which may be part of a psychiatric condition.

The Checklist aims to help staff and carers to identify potential mental health problems and decide whether a further assessment of an individual's mental health may be helpful.

Moss-PAS (Check) can be used to screen whole groups of individuals, or as part of a regular monitoring of people who are considered to be at risk of mental illness. The scoring system includes threshold scores which, if exceeded, indicate the presence of a potential psychiatric problem. This may then be more fully assessed using Moss-PAS (ID) or Moss-PAS (Diag ID).

The score forms with guidance are available in packs of 20.
