The current study was designed to evaluate the effectiveness of the COPE Healthy Lifestyles TEEN program with adolescent females within a suburban high school setting. The program assessed changes in Body Mass Index, knowledge and behaviors relating to nutrition and physical activity and self-concept. The study also focused on participants' perspectives on program components and how those components facilitate change. The results of this study indicate the program increased knowledge relating to nutrition and physical activity; behaviors relating to physical activity; and self-concept. Given the on-going nature of the childhood obesity epidemic worldwide and the relationship between mental health and physical health, prevention and intervention programs that focus on these topics should continue to be a research priority. The impact both physical and mental health have on scholastic achievement should make these issues a priority for school staff. Additionally, the accessibility of students makes implementing programs within the school setting an effective way to significantly impact student outcomes.
