Abstract
The High Risk Adolescent Trauma Prevention Program is situated in a teaching hospital setting, where adolescents who are considered to be high risktakers tour a shock trauma unit. Results from a pretest-posttest longitudinal evaluation design with 351 adolescent participants indicated marked changes in participants' attitudes toward driving after drinking, riding with someone who has been drinking and preventing a friend from driving after drinking. These changes in attitudes are still evidenet, though with some decline in magnitude, after twelve months.
