The Ph.D. program in Psychology and Social Intervention prepares action scientists to transform and improve the contexts and systems in which people develop throughout their lives. The program places a strong emphasis on analysis and prevention of psychological, social, educational, and health problems, as well as on the promotion of well-being, within families, small groups, school, communities, and neighborhoods from a systems perspective, including organizational, community, and policy levels. Working in faculty-led applied research teams and through closely supervised practica, students translate research into action by analyzing prevention and intervention programs such as those pertaining to school readiness, school success, HIV and health behaviors, mental health, housing, and homelessness. Graduates are prepared for diverse roles in academia in the areas of human development, education, public health, and public policy; for positions in policy research, advocacy, and social service organizations; and for positions that contribute to the design and implementation of evidenced-based strategies in health, education, and social services.
