我们比较了部分间隔记录（PIR）和瞬时时间采样（MTS）估计与自闭症或广泛性发育障碍幼儿刻板行为的实际持续时间的连续测量-未另行说明。使用低技术持续时间记录方法对22个刻板印象的录像样本进行评分，并对相对持续时间（即，计算刻板症消耗的观察期比例）。然后，10，20和30秒MTS和10秒PIR估计的相对持续时间从原始持续时间数据。在所有样本中，PIR被发现严重高估了刻板印象的相对持续时间。瞬时时间采样高估和低估的相对持续时间的刻板，但比PIR（实验1）的误差小得多。这些结果在27个低、中和高刻板印象水平的样本中重复（实验2）。(C)2004爱思唯尔有限公司保留所有权利。
We compared partial-interval recording (PIR) and momentary time sampling (MTS) estimates against continuous measures of the actual durations of stereotypic behavior in young children with autism or pervasive developmental disorder-not otherwise specified. Twenty-two videotaped samples of stereotypy were scored using a low-tech duration recording method, and relative durations (i.e., proportions of observation periods consumed by stereotypy) were calculated. Then 10, 20, and 30 s MTS and 10 s PIR estimates of relative durations were derived from the raw duration data. Across all samples, PIR was found to grossly overestimate the relative duration of stereotypy. Momentary time sampling both over- and under-estimated the relative duration of stereotypy, but with much smaller errors than PIR (Experiment 1). These results were replicated across 27 samples of low, moderate and high levels of stereotypy (Experiment 2). (C) 2004 Elsevier Ltd. All rights reserved.
