Good afternoon, I apologize about the inconvenience, however I was hoping that someone out there could provide me with information (or point me in the right direction) on valid and reliable instruments that assess/measure a persons’ knowledge on alcohol and drug use. While I’ve identified a number of assessment instruments for persons who may be using alcohol and drugs, I’m not identifying instruments for persons who may be learning about alcohol and drug use. My program offers a certificate program on substance abuse and I’d like to begin examining changes (if any) in the knowledge of our students (at the beginning and end of the program). Any assistance that you can provide would be welcome and greatly appreciated. Best.
