PATSy is primarily designed to be a raw data archive that serves both research and education in various ways. It is recognised that the requirements for rigour and detail in research and education vary in some contexts and the categorisation of PATSy cases into "Demonstration" and "Research" cases is intended to capture this difference.

The following definitions will help the contributor decide whether the case under consideration is a "Demonstration" or a "Research" case. It is understood that Research cases can serve as Demonstration cases.

Definition of a Demonstration case

This category is intended to refer to contributions that demonstrate one or any of these: a behavioural event, a clinical procedure, or an assessment. The material may be too sparse to serve research but offers educators examples for illustrative or demonstration purposes.

Some examples of a demonstration case might be:

• a) Demonstrating how to administer and interpret Test X
• b) Demonstrating the difference between flaccid and spastic dysarthria
• c) Demonstrating how to conduct a clinical interview with a depressed patient

The following crietria are applied when determining whether the material contributed has 'educational value' as a demonstration case.

Criteria (to be decided)

(Will probably look to setting up a small PATSy steering group or similar in future to help with this).

Definition of a Research case

The material of a participant may be categorised as a research case on the following bases:

• The participant's disorder has been comprehensively described by normed tests or tasks such that other researchers may reanalyse the data (for whatever purpose)
• The quality of the data is good i.e. the data is clear and intelligible. Rigorous methods of data collection are implied.
• The participant is reported in a published journal paper either as a single case study, case series or a group study. (optional)

There are 2 main reasons for contributing a "Research" case to PATSy. These are:

• a) Archiving data, especially if the participant represents a rare or unusual case or even a 'typical' case.
• b) Supplementing a journal publication by storing the participant's raw data on PATSy (as a rich Appendix) for journal readers to consult.
