The Teenage Health Teaching Modules (THTM) program is a health education curriculum for adolescents. Each THTM module frames an adolescent health task emphasizing development of self-assessment, communication, decision making, health advocacy, and self-management. This module deals with the epidemiology or nationwide patterns of injuries, and the etiology or causes of injuries. It acquaints young people with some of the concepts from evolving fields of injury control and describes both active and passive prevention measures they can take in their own lives. Students are also introduced to the rudiments of emergency treatment. Class activities are outlined to instruct students in: (1) examining and analyzing injuries data and learning that injuries are both predictable and preventable; (2) analyzing five investigative reports and determining what environmental factors and what lapses in knowledge, attitudes, and behaviors played a role in the fatality or serious injury; (3) reading and discussing news stories, considering questions based on them regarding passive interventions, and practicing them by role playing situations; and (4) learning about the desirability of knowing how to react in an emergency situation.
