The Moss-PAS-(Diag ID) has been designed to meet the particular problems of assessment in people with intellectual disabilities, but is equally valid for use with the general population. It provides full diagnoses under both the ICD-11 and DSM-5 (TR), and also provides a framework for producing a wider case formulation using other assessment frameworks (behavioural, ecological, psychodynamic etc).
The interview is designed to maximise the possibility of conducting a clinical interview, even if the client’s level of language is poor. Questions are also provided for informants so that the interviews can be conducted with a client and informant, or just with an informant if the client is non-verbal. Information can be collected not just on current mental state, but also on a second representative episode.
The Moss-PAS (Diag ID) uses a scoring system that is transparent to the user, making it very clear to see not just the criteria that have been fulfilled but also those that are close to fulfilment. This makes the process of clinical interpretation easier and based on clear evidence.
The score forms are for recording the ratings, determining which diagnostic criteria have been met, and bringing together other relevant information to make a comprehensive case formulation.
