Sexual Trauma Services of the Midlands (STSM) is a non-profit organization located in South Carolina focused on providing services for survivors of sexual assault, as well as community education to identify and prevent sexual violence. One of these programs, the Building Health Communities Curriculum (BHCC) (previously known as the Youth Violence Prevention Program), was developed for use with middle and high school students. The BHCC curriculum has as a goal educating adolescents in order to prevent sexual and relationship violence. STSM contracted with the Center for Research and Reform in Education (CRRE) at Johns Hopkins University to conduct an evaluation of prior implementations of that program to determine program effectiveness. In addition, CRRE was to provide recommendations to improve ongoing data collection and internal evaluation processes. The data collection and internal evaluation recommendations were provided in an interim report in October 2019, while the program effectiveness results will be reported on in the current final report. The study employed a one-group, pre-post correlational study design to address the following research questions: (1) What was the effect of BHCC curriculum on middle and high school students' knowledge, attitudes, and beliefs about sexual and relationship violence? (2) Did the effects of the BHCC curriculum differ by student factors, such as grade level, gender, race/ethnicity? and (3) To what extent were the number of BHCC sessions students attended associated with improved attitudes and beliefs about sexual and relationship violence?
