Preliminary Investigation of the Reliability and Validity of a Tool for the Assessment of Body Position and Motor Activity

Abstract
A recently developed tool which symbolically records body position, gross motor activity, and the intensity of this activity has potential for use in a variety of settings. To examine the instrument for interrater reliability and validity, activity of 14 children engaged in normal play was observed and recorded by two raters. Scores obtained were compared to actometer scores. The technique, it was concluded, is a reliable and sensitive method of assessing and recording changes in body position and activity levels which warrants further study in other situations.
