This study provides a preliminary validity analysis of the two versions of the MED-AUDIT: the Black Box and the Expert User. Research questions explored subjective post-use face and administrative validity for the two versions. The study found that both versions demonstrated similar indices for face validity in terms of comprehensiveness of questions covered in the assessment. Results for administrative validity showed that there were significant differences in times required to score the two versions with the Black Box requiring lesser time than the Expert User (5). However, there were no differences in participants’ perceptions of the ease of scoring the two versions or in the amount of training required. This study is the first step in the validation of the MED-AUDIT and will play a significant role in future studies as well as further development.

Disney produced a television show in the mid 1990s called Gargoyles. It's a great show and I'm a big fan. A few years ago Disney started to release the show on DVD. The last release was of season 2, volume 1. That was two years ago. Volume 2 has not been released. Why? Poor sales. So if you should find yourself wanting to support my work, instead I ask you pick up a copy of season 2, volume 1. It's a great show and you might find yourself enjoying it.
