Book excerpt: This study attempted a norming and validation of the Purdue Perceptual Motor Survey, using grade one students. One hundred and ninety seven pupils, 99 boys and 98 girls, participated in the study. These pupils were randomly selected from 13 public schools throughout the County of Strathcona, Alberta, Canada. The schools involved served families from a wide variety of socioeconomic backgrounds. Nineteen subtests of the Purdue were administered individually to each child in November of their grade one year. Scoring criteria recommended by the authors of the test, Newell C. Kephart and Eugene Roach, were adhered to. Retesting of 28 children from the original sample occurred one week after the initial testing. The Otis Lennon Intelligence and Metropolitan Achievement Tests were administered to each child in September and May, respectively, of the same school year. These group tests were administered routinely as part of the County's core testing program. In norming the survey, means and standard deviations were obtained for all item and subtest scores, as well as for total test scores. The effects of sex and socioeconomic background on total test performance was considered using pairwise contrast of means. The internal consistency of subtest and total test scores was assessed using Cronbach's Coefficient Alpha. Test-retest reliability was obtained for subtest and total test scores. The validation phase of this study focused on considering statistical support for the five theoretical constructs of perceptual motor functioning which are included in the survey: Balance and Posture; Body Image and Differentiation; Perceptual Motor Match; Ocular Control, and Form Perception. Item scores were subjected to factor analysis for this purpose. The value of the Purdue Survey as a predictor of academic achievement was considered by using Pearson product moment correlations obtained between survey item and Metropolitan Achievement test scores. The relationship between intelligence and perceptual-motor proficiency was also considered by examining correlations between survey item and Otis Lennon scores. The results of factor analysis carried out on Purdue items suggested support for the five constructs of perceptual motor functioning proposed by Kephart and Roach. However, modifications to the item content of four of the subtests were suggested by both the factor analysis and investigation of intercorrelations between Purdue items. Internal consistency of Purdue subtests, as assessed by Cronbach's coefficient alpha, was statistically weak, with Ocular Control being the only exception. It was suggested that the recommended modifications to subtest content revealed by the factor analysis could also result in improved internal consistency. More stringent and objective scoring criteria were suggested for improving reliability of the subtest Form Perception. Further research in this area is necessary. Analysis of intercorrelations between Purdue subtests, academic achievement and intelligence revealed that Identification of Body Parts was consistently the best predictor of academic achievement and intelligence. Items from the subtests Ocular Control, Balance, and Body Image and Differentiation also correlated with academic achievement. The Kraus-Weber and Obstacle Course items were assessed in this study as being of minimal value in contributing to either construct validity or prediction of academic achievement. Although significant correlations were found to exist between perceptual- motor efficiency and academic achievement, results were interpreted only as associations.
