I've spent the last few years working part-time on a joint project with three members of the Clinical Psychology Department. The project has been funded by the Department of Health. The package we've produced is designed to be used by children to describe how they feel about places, people and events. It runs on Macintosh systems.
I wrote up the development of the package as an MPhil thesis. This took a long time because I'm not used to writing very large documents!
The package consists of a series of modules, which are designed to be used by a trained interviewer. The modules allow the interviewer and child to explore the child's "universe". The modules that existed when I wrote my thesis were:
Emotions & People
Here's more information about the package modules, and here's my thesis on-line.
