本研究的目的是检验惠特尼应变计测量早产儿营养性吸吮的同时有效性。十名早产儿从进入研究直至离开托儿所，每周至少进行一整瓶奶喂养的连续研究。通过适配的乳头和惠特尼量规同时测量吸吮。这两种仪器在以下指标上进行了比较：吸吮突发次数、每次突发吸吮次数以及突发持续时间和突发之间的暂停。吸吮爆发发生的总一致性百分比为 99.3% (K = .99)。每次突发吸吮次数从 2 到 113 不等，其中 89.3% 的吸吮突发对每次突发吸吮次数相差 ≤ 1。两种仪器的吸吮爆发和暂停持续时间的平均绝对差异分别为 0.64 秒和 0.72 秒。这些结果证明了惠特尼量规测量早产儿吸吮事件的同时有效性。
The purpose of this study was to examine the concurrent validity of the Whitney strain gage for the measurement of nutritive sucking in preterm infants. Ten preterm infants were studied continuously during at least one entire bottle feeding per week, from admission into the study until discharge from the nursery. Sucking was measured simultaneously by an adapted nipple and the Whitney gage. The two instruments were compared on the following measures: number of sucking bursts, number of sucks per burst, and duration of bursts and pauses between bursts. Total percent agreement for the occurrence of a sucking burst was 99.3% (K = .99). Sucks per burst varied from 2 to 113, with 89.3% of the pairs of sucking bursts differing by ≤ 1 suck per burst. The mean absolute difference between the two instruments for the duration of sucking bursts and pauses was .64 s and .72 s, respectively. These results demonstrate the concurrent validity of the Whitney gage for measurement of sucking events in preterm infants.
