A SERVICE PROGRAM FOR MOTHER-DAUGHTER GROUPS WHICH WAS ESTABLISHED AS PART OF A DELIQUENCY PREVENTION PROGRAM IS DESCRIBED AND EVALUATED IN THIS REPORT. THE PROGRAM WAS SET UP TO REDUCE COMMUNICATION BARRIERS BETWEEN THE MOTHERS AND DAUGHTERS AND TO HELP THE MOTHERS COPE WITH THE CHILD-REARING PROBLEMS OF POOR, ONE-PARENT FAMILIES. ALL OF THE MOTHERS EXCEPT ONE WERE RECEIVING AID TO FAMILIES OF DEPENDENT CHILDREN (AFDC) AND ALL OF THE GIRLS WERE IN EITHER THE FIFTH OR SIXTH GRADE. ONE SET OF MOTHERS AND DAUGHTERS WAS REFERRED BY THE SCHOOLS BECAUSE THE GIRLS HAD BEHAVIOR PROBLEMS (THE SCHOOL GROUP), AND THE OTHER SET WAS SUGGESTED BY THE AFDC CASEWORKER (THE AFDC GROUP). THE GROUP WORKER FOR THE SCHOOL GROUP USED A RECREATION-ACTIVITY THERAPY APPROACH, WHEREAS THE CASEWORKER FOR THE AFDC GROUP USED A METHOD SIMILAR TO A FAMILY EDUCATION APPROACH. OPERATIONAL DIFFICULTIES MADE IT IMPRACTICAL TO EVALUATE SYSTEMATICALLY THE HYPOTHESIS THAT IMPROVING COMMUNICATION WOULD BENEFIT FAMILY RELATIONSHIPS. DISCUSSIONS OF THE PROBLEM, THE PURPOSE AND METHODS OF THE PROGRAM, RESULTS, AND RECOMMENDATIONS AND OBSERVATIONS ARE INCLUDED IN A GENERAL SECTION, WHILE ASPECTS OF ADMINISTRATION, STAFFING, BUDGET, OPERATING STATISTICS, COMMUNITY INVOLVEMENT, AND EVALUATION METHODS MAKE UP A SECOND PART.
