I have been involved in the development of a behavior scale that has the ability to measure changes in patients involved in treatment for mental illness or other behavioral difficulties. I would like to discuss this area of interest with those who are looking for ways, not only to make objective measurements of change, but also those who are looking for ways to motivate patients/clients to participate more effectively in treatment. I believe this area is increasingly important in the age of managed care and has the potential to be a valuable tool.
