The NIDA International Program and Division of Epidemiology, Services and Prevention Research (DESPR) cosponsored a poster session for international research at the Society for Prevention Research (SPR). The poster session opened the SPR Annual Meeting, which was held May 27–30, 2014, in Washington, DC. SPR President Felipe Gonzalez Castro, Ph.D., University of Texas at El Paso; DESPR Prevention Research Deputy Branch Chief Jacqueline Lloyd, Ph.D., M.S.W.; and International Program Associate Director Dale S. Weiss welcomed attendees to the poster session. NIDA supported the participation of five international researchers: Antonio Cesar Pazinatto, Brazil; Angela Trujillo, Colombia; Gergely Radacsi, Hungary; Shreeletha Solomon, India; and Joachim Jacobs, South Africa. Ms. Weiss also participated in the preconference meeting of the SPR International Networking Forum, which discussed plans to develop a guide for sustaining successful international collaborations. The guide will review developing research questions, the impact of cultural influences on working relationships, and collaborative strategies for analyses, writing, and dissemination.
