The test-retest reliability of the Multiple Sleep Latency Test (MSLT) was evaluated in 14 healthy normal subjects. Each slept a single night in the laboratory (8 h time in bed) and received the MSLT the following day (1000, 1200, 1400, and 1600 h) on two occasions separated by 4-14 months. Mean sleep latency (four tests) was highly reliable from MSLT to MSLT (r = 0.97, p less than 0.001). The test-retest reliability did not change as a function of the interval of time between tests or as a function of the level of sleepiness (range = 4-20 min) within the population. However, as the number of tests comprising the MSLT was reduced below three, the reliability was reduced such that only 50% or less of the variance could be predicted.
对14名健康正常受试者评估了多次睡眠潜伏期试验（MSLT）的重测信度。每位受试者在实验室睡一晚（卧床8小时），并于次日（10:00、12:00、14:00和16:00）进行两次MSLT，两次测试间隔4至14个月。从一次MSLT到另一次MSLT，平均睡眠潜伏期（四次测试）的信度非常高（r = 0.97，p < 0.001）。重测信度不会随测试间隔时间或人群中嗜睡程度（范围为4至20分钟）而变化。然而，当组成MSLT的测试次数减少到三次以下时，信度会降低，以至于只能预测50%或更少的方差。
