本研究探讨了百分比时间估计的瞬时时间采样对真实的时间获得的手持电脑在自然环境中。22个同时进行的观察，在小学的一个观察员谁使用15秒的瞬时时间采样和第二个谁使用手持电脑。结果表明，6个行为的瞬时时间采样百分比观察间隔和真实的时间百分比观察时间之间的密切对应关系，虽然15秒瞬时时间采样往往不采样低频短持续时间的行为。结果证实了实验室的研究结果，即短间隔瞬时时间采样准确地估计了广泛的行为频率和持续时间的百分比时间，并建议观察者在自然环境中使用瞬时时间采样能够获得准确的数据。
This study examined the percentage time estimates of momentary time sampling against the real time obtained with handheld computers in a natural setting. Twenty-two concurrent observations were conducted in elementary schools by one observer who used 15-s momentary time sampling and a second who used a handheld computer. Results for the six behaviors showed a close correspondence between the momentary time sampling percentage observation intervals and the real time percentage observation time, although 15-s momentary time sampling tended not to sample low-frequency short-duration behaviors. The results confirmed laboratory findings that short-interval momentary time sampling estimates percentage time accurately for a wide range of behavior frequencies and durations, and suggested that observers using momentary time sampling in a natural setting are able to obtain accurate data.
