This paper addresses the role of the local Head Start program mental health consultant and outlines ways in which the program can assure optimal use of the consultant's services. The Head Start program incorporates the services of a local consultant to promote the mental health of children and parents. The specialist's role is to assist staff and parents to better understand the relationship between their actions and the affective growth of their children. Successful implementation of the mental health component demands the same type of careful planning and coordination as the other components. The Head Start program staff should consider the following general areas in developing a comprehensive mental health component: (1) coordination of the mental health consultant's services, (2) the specific services to be performed by the consultant, (3) planning meetings to clarify expectations and responsibilities, and (4) procedures for documenting the activities of the mental health component. One staff person should be designated to coordinate mental health component activities. Responsibilities of the consultant include teacher inservice, classroom observation, and teacher/parent consultation. Detailed plans for consultant services should be made early in the year. Forms to use in the mental health component are described and sample forms are included. A consultation model suggesting scheduling and costs is provided. (Author/RH)
