The Unitas Therapeutic Community is a mental health treatment and prevention program for Hispanic and Black children and teenagers in the South Bronx, New York City. Based on theories of therapeutic community and social psychology, Unitas stresses psychological methodologies that cultivate the healing potential present in all interpersonal relationships. Specifically, Unitas has set up a caretaker system in which trained neighborhood teenagers are available to serve as symbolic "parents" for other youths in need of services. Intended to guide those who plan to replicate Unitas in other settings, this monograph outlines the steps taken in establishing the South Bronx program, describes Unitas therapeutic methods and techniques, and presents the curriculum used in training Unitas clinical staff and youth workers. Part I explains how Unitas was conceived and initiated in the South Bronx. Part II describes the process of building the caretaker network, and includes teenagers' own accounts of their involvement as program workers. Part III discusses the theoretical framework of Unitas and its application in practice. Finally, part IV presents the staff training program, which comprises five modules: (1) development of self regard; (2) empathetic communication; (3) conflict resolution; (4) group dynamics; and (5) therapeutic community. For each module, objectives and suggested activities are included. (MJL)
