沃伦·伊顿用活动计测量活动水平：可靠性，有效性和臂长。《儿童发展》，1983年，第54，720 -726页。27名3岁和4岁儿童的粗大运动活动采用教师评分、父母对科罗拉多儿童气质量表活动量表的反应和13个未校准的动作计单独戴在手腕上，为期1个月，在自由玩耍环境中进行测量。活动分数从单一的actometers有低，但有意义的可靠性水平;活动分数复合在多个actometers有很高的可靠性和强烈的相关性与家长和教师的措施，即使年龄和性别的影响是partialled。肢体长度是一个混淆因素的手腕放置actometers的可能性也进行了评估，虽然在这个方向上的一个不显着的趋势被发现，有效性相关性基本上没有变化时，臂长的影响被删除。肢体长度混淆似乎并不严重，当使用适当的actometers提供可靠和有效的信息，儿童的粗大运动活动水平的个体差异。
EATON, WARREN O. Measuring Activity Level with Actometers: Reliability, Validity, and Arm Length. CHILD DEVELOPMENT, 1983, 54,720-726. The gross motor activity of 27 3and 4-yearolds was measured using teacher ratings, parent responses to the activity scale of the Colorado Childhood Temperament Inventory, and 13 uncalibrated actometers worn singly on the wrist over a period of 1 month in a free play setting. Activity scores from single actometers had low but meaningful levels of reliability; activity scores composited across multiple actometers had high reliability and correlated strongly with parent and teacher measures, even when age and sex effects were partialled. The possibility that limb length is a confounding factor of wrist-placed actometers was also evaluated, and though a nonsignificant trend in this direction was found, validity correlations were essentially unchanged when arm-length effects were removed. The limb-length confound does not appear serious, and when used appropriately actometers provide reliable and valid information on individual differences in children's gross motor activity levels.
