One key objective of California's Prevention and Early Intervention (PEI) Student Mental Health (SMH) initiative funded under Proposition 63 is to establish a formal process for ongoing collaboration between higher education systems and county mental health, as well as to increase collaboration among higher education campuses to improve student mental health. With effective collaboration, diverse student bodies in California's colleges and universities will have increased access to a wider array of services, including linkages to local community mental health and substance abuse prevention and treatment partners. In addition, collaboration fosters the collective efforts of campuses to develop, implement, and share innovative and culturally responsive practices and policies, which further increases the capacity, quality, and efficiency of student mental health programs statewide. As part of its evaluation of activities funded under Proposition 63, SRI International and RAND researchers are evaluating the development, quality, and effectiveness of collaboration among SMH program partners in higher education. Through multiple methods, including document reviews, key informant interviews, and participant surveys, the SRI research staff is collecting data about the development, function, and goals of collaborative activities; the ongoing challenges and facilitators to successful collaboration; and the degree to which collaboration activities contributed to short- and long-term outcomes relevant to SMH PEI services and supports. The SRI research team consulted with the California Mental Health Services Authority (CalMHSA) program coordinators and partners at college and university campuses and Chancellor's Offices to identify individuals who participate in collaborative activities and represent various administrative roles in different locations. These individuals, nominated to participate in the interviews due to their personal and professional involvement in SMH partnerships, were in positions to judge the benefits and challenges of collaboration. This document reports preliminary findings from 34 interviews conducted with these SMH key informants in Fall 2013, for each higher education system.
