Recognizing the prevalence of health risk behaviors in the adolescent population and the reported inconsistency of high school health education, medical students at the University of Michigan designed a program, ‘MiHealth,’ in which medical students teach health lessons in the high school classroom. A series of six lessons were created and implemented in the classroom each with a topic of sexual health, intimate partner violence, mental health, smoking and drugs, nutrition, and physical fitness. High school students in grades nine through twelve at a public high school in southeast Michigan receiving the MiHealth curriculum or the standard health education curriculum were surveyed on health knowledge, attitudes, and intentions before and after the program. This forty-four-item questionnaire was created to assess the effects of the MiHealth lessons on high school students’ knowledge, attitudes, and intentions related to health and risk behaviors. The questionnaire was created denovo based on lesson learning objectives, with input from MiHealth curriculum development faculty advisors to ensure quality and neutrality of the questions. The anonymous questionnaire was administered to participating health classes in the week directly preceding MiHealth and six weeks after MiHealth completion to assess the effects of the program.
