The Infant Monitoring Project was initiated in Polk County, Oregon, to address the need for monitoring the development of infants and young children designated as "at risk." The project involved a cooperative effort between the Polk County Health Department and the Teaching Research Division of the Oregon State System of Higher Education. The project used a series of questionnaires mailed at intervals to parents to measure infant development from birth through age 3, without involving professionals or transporting the child to a test site. A total of 755 questionnaires covering biological and environmental risk factors and family history were distributed over a 2-year period, and 500 were returned. Overall, 11% of the questionnaires showed abnormal results, while the project as a whole showed that lack of parenting skills were a high predictor of developmental problems. The project led to the development of a parent support group and referrals to local physicians. Concern is expressed about the number of children who may "fall through the cracks" in this type of screening program. (JDD)
