Project Chrysalis, funded by the Center for Substance Abuse Prevention, is a two-year program for high school girls, 14 to 15 years old, who have been victims of sexual, emotional, and/or physical abuse. Many girls also face additional risk factors (including substance abuse, academic failure, and economic disadvantage). Program components include: weekly support groups and workshops focusing on life skills, self-esteem, drug education, and relationships; "Girls Empowerment," self-defense and assertiveness training, which teaches girls to define danger, practice street safety, differentiate between flirting and sexual harassment; and a one-day challenge course (held in a gym and offering group and individual physical challenges) designed to teach leadership skills, cooperation, positive risk-taking, persistence, and personal responsibility. High school staff serve as case managers. In addition to the 328 girls in Project Chrysalis, another 297 girls with similar backgrounds comprise a research comparison group.
