A The PROMIS Pediatric Physical Activity (PA) measure is a new instrument with established validity that measures a child self-report on short bouts of moderate to rigorous physical activity. The purpose of this study was to explore the relationship of the PROMIS Pediatric PA item bank with cardiorespiratory fitness and self-efficacy. The study was conducted at the Minnesota State Fair. Youth ages 8 to 18 years completed the PROMIS Pediatric PA and the Self-Efficacy for PA measures on an iPad. Participants performed 3-min step test with heart rates measured 1 min posttest. Participants (N = 182) were 53% female. The PROMIS Pediatric PA had a weak, significant negative correlation with the step test measurement = -0.23, = 0.001) and a weak, significant positive correlation with self-efficacy ( = 0.27, < 0.001). Measurements did not differ between groups by sex or age group (school-age and adolescent). Youth who were obese had significantly higher heart rates post step test ( = 0.004); BMI percentile groups did not differ in other measures. Self-report of PA and the physiologic measure of heart rate are from two related but different physical fitness domains which supports their significant but weak relationship.
A “患者报告结果测量信息系统”（PROMIS）儿童身体活动（PA）量表是一种新的工具，具有已确立的效度，用于测量儿童对短时间中等至剧烈身体活动的自我报告。本研究的目的是探讨PROMIS儿童PA题库与心肺适能及自我效能之间的关系。该研究在明尼苏达州博览会上进行。8至18岁的青少年在iPad上完成了PROMIS儿童PA量表和PA自我效能量表。参与者进行了3分钟的台阶测试，并在测试后1分钟测量心率。参与者（N = 182）中53%为女性。PROMIS儿童PA量表与台阶测试测量值呈弱的、显著的负相关（r = -0.23，P = 0.001），与自我效能呈弱的、显著的正相关（r = 0.27，P < 0.001）。测量结果在性别或年龄组（学龄儿童和青少年）之间没有差异。肥胖青少年在台阶测试后的心率显著更高（P = 0.004）；BMI百分位组在其他测量方面没有差异。PA的自我报告和心率的生理测量来自两个相关但不同的身体素质领域，这支持了它们之间显著但微弱的关系。
