Since the early 1990s, the PAS-ADD tools have been increasingly used for the assessment of mental health problems in adults with intellectual disabilities (ID). They are now widely used throughout the world.

The PAS-ADD Checklist is a questionnaire written in everyday language for use by care staff and families to identify potential mental health problems and to help decide whether a further assessment is needed. It is designed to record the presence of a range of problems, all of which may be part of a psychiatric condition.

The Moss Psychiatric Assessment Schedules (Moss-PAS) are the successors to this well-known PAS-ADD system. Click here to purchase the updated system.



The PAS-ADD checklist is to be completed primarily by carers and families of people with intellectual disabilities who will have the most immediate perception of changes in the behaviour of the people they care for.
