A THIRD AND FINAL PHASE OF A THREE-PHASE PSYCHOLOGICAL SERVICE PROGRAM WAS COMPLETED DURING THE SUMMER OF 1967. THIS "CHILD STUDY" SERVICE WAS CARRIED OUT IN THE HEAD START CENTERS OF THE DELTA REGION OF SOUTHEAST MISSOURI. THE CHILDREN ATTENDING THE HEAD START PROGRAM WERE ABOUT EQUALLY REPRESENTED BY CAUCASIANS AND NEGROES. AN AVERAGE OF 5 YEARS OLD, THE CHILDREN CAME FROM FAMILIES OF A QUITE LOW SOCIOECONOMIC LEVEL. THE PSYCHOLOGICAL SERVICE PROGRAM WAS SUPPLEMENTARY TO THE HEAD START PROGRAM. ITS PURPOSE WAS TO MAKE COMPREHENSIVE PSYCHOLOGICAL STUDIES OF CHILDREN REFERRED TO IT BY THE HEAD START PROGRAM PERSONNEL. THE SERVICE ALSO PROVIDED AN IN-SERVICE TRAINING OPPORTUNITY FOR TEACHERS AND OTHER HEAD START PEOPLE. THE PSYCHOLOGICAL SERVICE STAFF WAS COMPOSED OF VARIOUS SPECIALISTS WHO WERE COMPETENT TO CONTRIBUTE TO THE ANALYSIS AND RESOLUTION OF THE REFERRED CHILD'S PROBLEMS. THE STAFF VISITED 23 HEAD START CENTERS AND EXAMINED 45 CHILDREN. THE EXAMINATION OR EVALUATION OF THE CHILD INVOLVED OBSERVATION, TESTING, AND DISCUSSION OF THE RESULTING DATA. ALL THOSE PROFESSIONALLY INTERESTED IN THE CHILD, THAT IS, TEACHERS, SOCIAL WORKERS, AND DOCTORS, COULD PARTICIPATE IN THE DISCUSSION SESSIONS. THESE SESSIONS PLUS NUMEROUS CASE PRESENTATION DAY SESSIONS PROVIDED THE PARTICIPANTS WITH INSIGHT AND UNDERSTANDING OF THE CHILD'S NEEDS AND WITH WAYS OF MEETING THOSE NEEDS. MOST OF THE 45 CHILDREN WERE REFERRED AS BEHAVIOR PROBLEM CHILDREN, BUT, UPON EXAMINATION, MOST OF THEM WERE FOUND TO SUFFER FROM CENTRAL NERVOUS SYSTEM PROBLEMS. (THE APPENDIX OF THIS STUDY CONTAINS A REPRESENTATIVE CHILD STUDY REPORT AND SPEECH-AND-HEARING REPORT.) (WD)
