Psychometric properties of the physical activity level screening (PALS) for preschoolers with a developmental delay and/or a disability were examined in this study. The mean age of participants (16 boys and 14 girls) was 54.9 months (standard deviation, 10.4). Each participant wore one Actical accelerometer and was filmed for 20 min during the active play time. Intrarater and interrater reliability, and validity of the PALS data were examined. The proportion of agreement for intrarater was 87.5% and 85.6% for interrater reliability. Intraclass correlation coefficients were 0.99 for intrarater and 0.96 for interrater. The PALS data showed moderate correlation with Actical data (=0.67, <0.01).
本研究考察了针对发育迟缓及/或残疾学龄前儿童的身体活动水平筛查（PALS）的心理测量学特性。参与者（16名男孩和14名女孩）的平均年龄为54.9个月（标准差为10.4）。每位参与者佩戴一个Actical加速度计，并在活跃玩耍时间拍摄20分钟的视频。考察了评分者内信度、评分者间信度以及PALS数据的效度。评分者内一致性比例为87.5%，评分者间信度为85.6%。组内相关系数评分者内为0.99，评分者间为0.96。PALS数据与Actical数据呈中度相关（=0.67，<0.01）。
