Recognized nationally and internationally as a leader in risk behavior prevention research with adolescents, he has published over 60 articles and book chapters and has received numerous grants from the National Institute of Health to support his research.
Dr. Jemmott developed the Pre-Test and Post-Test for the Positive Choice Program. The Pre-Test is given at the beginning of the program, or at the participants' first encounter, to measure the participants' knowledge of risky behaviors, what risky behaviors they have experienced, and how risky behaviors will affect their lives now and in the future. The Post-Test is given after the completion of the program to measure participants' understanding and any changes in attitude and behavior toward risky behaviors, including premarital sexual activity and the use of drugs and alcohol. Finally, the Post-Test assesses the participants' commitment towards sexual abstinence at the end of the program.
