Does your service currently do any form of routine evaluation? If so, how well does it work? What could be improved? If not, what might be the pros and cons of doing some? How might you persuade your colleagues and/or managers that it would be a good idea?
Evaluate your interventions. It is always good practice to develop ways of assessing the impact of your therapy and it is even more important to do this when you are using approaches that are relatively new or, as yet, have little empirical foundation.
