Thanks so much for sharing your thoughts! You are absolutely correct. Sharing the results does change the goal of the tool. If you want to simply measure progress in social interaction, which is extremely important and a much needed measurement tool for mental health professionals, GPPRS is quite helpful. Used as an intervention, it must no longer be considered a simple measurement without bias. It is an interesting question to ponder where the greater value is to be found. Your point, however, is well taken. GPPRS does take on a different character and purpose when used as an intervention. I would like to see GPPRS used primarily as a measurement tool. In my desperate search for interventions for teens who struggle to maintain their composure in the group setting, I have been able to demonstrate a measurable degree of success. Thanks again for your thoughts. chumn@accessus. net
