This report describes a pilot project which involved the development and evaluation of an experimental treatment (training program) suitable for a longitudinal study in which the effects of child rearing practices on general competence in young children are being studied. Eleven families participated in the pilot training program which concentrated on teaching parents successful child rearing practices prior to and during the period when identified educational foundations are at risk in infants 8 to 24 months of age. Both group training sessions and home visits were included in the program. Evaluation methods included home observation of parent-child interactions, child behavior in social and nonsocial tasks, and children's social competence; and several administrations of the Bayley Scales of Infant Development and the Preschool Project Tests to determine language ability, capacity for abstract thought, and the capacity to sense discrepancies. Results indicated the program was reasonably effective. Appendices make up more than 3/4 of the report and include: (1) criteria for family selection and the eligibility and preliminary interview forms; (2) the working draft of the training program (more than 1/2 of the report); (3) checklists and rating scales of the adult assessment scale; and (4) scoring information for social competence observation.
