Avoiding misperceptions: classifying rehabilitation projects using letters rather than numbers.

A classification system proposed earlier of the many different known rehabilitation approaches and activities used a quantitative scoring system, thus giving the impression that projects with a higher score were better, more correct or more important than projects with a lower score. We therefore propose an alternative classification based on letters, so that a given combination of letters characterizes a particular type of project. The letters are derived from four dimensions: desired outcome of the intervention, participation of the clients in the rehabilitation process, the target group served and the services offered. Some examples are presented. The classification serves to analyse rehabilitation projects, to define policy and as a starting point for evaluation.
