Simultaneous observational recordings were made in vivo, via an observation mirror, and via closed circuit television. Three of nine observers had extensive experience recording behavior in vivo; three had extensive experience recording behavior via mirror; and three had extensive experience recording via television. Observers recorded nine categories of disruptive behavior for children in a special class setting. Frequencies of behavior recorded in vivo, via mirror, and via television differed significantly for only one category, vocalization. There were no significant main effects or interactions involving the observers' previous experience. Occurrence reliability coefficients computed within and between media demonstrated the similarity of observer agreement in all three media. Data collection procedures using an observational mirror or closed circuit television appear to be reasonable alternatives to in vivo observation in circumstances similar to those in the present study.
同时通过观察镜和闭路电视进行体内观察记录。9 名观察者中有 3 名具有丰富的体内行为记录经验，3 名具有丰富的镜下行为记录经验，3 名具有丰富的电视行为记录经验。观察者记录了特殊环境下儿童的 9 类破坏性行为。仅在一种行为，即发声方面，通过体内、通过镜子和通过电视记录的行为频率有显著差异。观察者先前的经验没有显著的主效应或交互作用。在三种媒体中，计算的媒体内和媒体间出现可靠性系数表明，在本研究相似的情况下，三种媒体中观察者的一致性相似。在类似本研究的情况下，使用观察镜或闭路电视进行数据收集的程序似乎是体内观察的合理替代方法。
