This study will enroll high school students. Participants will be randomly assigned to either a 12 lesson WLS program or a control group. Participants in the control group will attend regular high school classes. Participants in the WLS program will attend 12 sessions that will focus on coping skills to help manage stress and anger levels. At baseline, the end of the 12 lesson program, and follow-up visits 3 and 6 months later, participants will complete questionnaires on anger levels; life skills; hostility; stress; self-esteem; and attitudes toward school, teachers, and parents. They will also wear a blood pressure monitor for a 24-hour period.
