The Commercial Sexual Exploitation of Children (CSEC) project seeks to estimate the prevalence and typologies of CSEC in Pennsylvania. Funded by the Center for Rural Pennsylvania, the CSEC study involves reviewing and coding over 2,000 Pennsylvania's Children and Youth Services investigation records over a 2-year span. The goals of this study are to estimate the incidence of CSEC in the participating counties, to assess rural and urban differences in the incidence and typologies of CSEC, and to identify risk and protective factors for CSEC.  This research aims to inform current statewide efforts to develop and implement screening tools to detect children vulnerable to or affected by CSEC. Drs. Miyamoto, Pinto, and Font lead this project, and are assisted by undergraduate research assistants involved with the Child Maltreatment and Advocacy Studies (CMAS) minor at Penn State.
