Abstract

The Iowa Pegboard Fine-motor Task is a 60-sec. peg-placement task for use with preschool and school-age children. The instrument has demonstrated validity and reliability. Performance norms by age (means, standard deviations, and range) are presented for 865 observations (420 boys, 445 girls) of 510 Iowa children ranging in age from 33 to 138 mo. Regression analysis yielded the prediction formula: Ŷ = −8.205 + 0.619(age in mo.) − 0.002 (age in mo.)2. Moderate stability, based on 513 comparisons of repeated measures, is evident. Correlations of pegboard and PPVT scores, based on 541 observations of children 33 to 71 mo. of age, are positive and significant. The present findings enhance the use of the instrument in assessing current status of an individual child and/or in comparison within and between individuals.
