Abstract
Fetal alcohol syndrome (FAS) is an important cause of mental retardation and developmental disabilities. A population based screening tool would allow for early diagnosis and entry into intervention programs. The aim of the study was to develop a brief screening tool for use in population-based settings to improve the identification of children with FAS. The FAS Screen was developed and tested in six sites. These were sites that served children and all were located in North Dakota. Screening was completed on 1013 children, 65 were found to have a positive screening score and were referred for further investigation. Forty were seen for evaluation by a medical geneticist and six were diagnosed with FAS. The estimated values for the screening tool were: specificity 94.1%, sensitivity 100%, positive predictive value 9.1% and negative predictive value 100%. The cost of screening was $13.00 per child and the cost per case identified was $4,100. The FAS Screen is a brief screening test with acceptable performance characteristics and is cost effective.
