Television viewing habits, program preferences, and parental guidance at 5,167 randomly selected urban/rural Kansas children in grades 4-9 were studied. Data collected by the administration of structured questionnaires to the children in 254 classrooms and separate questionnaires completed by 4,882 of the childrens' parents indicated that: (1) the children devoted approximately 3-1/2 hours daily to television; (2) parental limitations on viewing times were more strict on nights before school days--70% and 90% of the children and parents, respectively, reported that viewing must cease at or before 10:00 p.m.--than on nights before non-school days--no parental limitations on viewing times were reported by 60% to 70% of the respondents; (3) parents and children frequently differed in program preferences, suggesting difficulties for broadcasters in providing "common denominator" programs appropriate for family viewing; and (4) 80% to 90% of parents and children reported no parental guidance on 68 evening and 24 Saturday morning programs listed on the questionnaires. Demographic analyses of the data are also reported. (Author/CMV)
