In the child mental health and child abuse fields, parent training has become a highly valued prevention and treatment service. A conceptual framework and a detailed description of three theoretically-based parent training approaches (Client-Centered, Adlerian, and Social Learning) are presented as background for this report on a two-year pilot testing of a professional training program (Personnel for Parent Development) for human services personnel. The training program teaches the three approaches mentioned through a general conference on parent training and a series of workshops that train personnel to deliver the services. Created by the Center for the Improvement of Child Caring in Los Angeles, the program is designed as a national model, and follow-up data on graduates of the two-year pilot phase indicate that they acquired knowledge and skills and are having an impact on the field of parent training. The program's current expansion phase is also described. (Author/MK)
