These summative evaluation results are part of the National Home Start Evaluation interim report. Home Start, a federally-funded 3-year (1972-1975) home-based demonstration program for low-income families with 3-to 5-year-old children was designed to enhance a mother's skills in dealing with her own children and to provide comprehensive social-emotional, health and nutritional services. The data presented in this report were collected from 434 families in six of the 16 Home Start sites operating in the spring of 1974. The families belonged to one of three groups, the Home Start group (192 families), the delayed-entry control group (130 families), or the Head Start group (112 families). Included are reviews of psychometric analysis such as Preschool Inventory, Denver Developmental Screening Test, Child 8-block Task, Child Food Intake Questionnaire, Schaefer Behavior Inventory, Pupil Observation Checklist, High/Scope Home Environment Scale, Mother Behavior Observation Scale, Parent Interview and, 8-Block Sort Task. A number of tables and charts are included in this report. (Author/MS)
