虽然精神运动警觉性任务（PVT）通常用于睡眠和其他研究环境，但关于儿童PVT表现的规范数据尚未发表。本报告介绍了参与图森儿童睡眠呼吸暂停评估（TuCASA）研究的无睡眠障碍儿童的正常PVT表现。TuCASA是一项以社区为基础的前瞻性研究，针对6至11岁的白人和西班牙裔儿童的睡眠呼吸障碍。一项标准的10分钟PVT试验由360名参与者完成，其中48%为女性，36%为西班牙裔；平均年龄8.9岁。对162名呼吸障碍指数< 1且无父母报告睡眠问题的儿童进行了详细分析。平均和中位反应时间（RT）随年龄的增加而降低（p趋势< 0.001）。6岁和11岁儿童的中位RTs分别为544.24和325.70 ms。RTs的标准差也随着年龄的增加而下降（p趋势= 0.001），失误也是如此（p趋势< 0.001），但总误差没有明显的趋势。男生和女生的成绩差异有统计学意义（p=0.006）。性别差异在6岁时最大，男孩的RTs较短，随着年龄的增长而减少，直到11岁时表现大致相等。没有发现种族差异。儿童的PVT表现随年龄的增长而提高，性别不同。当在儿科人群中使用PVT时，应考虑到这些差异。
Although the psychomotor vigilance task (PVT) is commonly used in sleep and other research settings, normative data for PVT performance in children have not been published. This report presents normal PVT performance measures among children without a sleep disorder participating in the Tucson Children's Assessment of Sleep Apnea (TuCASA) study. TuCASA is a community-based, prospective study of sleep-disordered breathing in Caucasian and Hispanic children ages 6 to 11 years. A standard 10-min PVT trial was completed by 360 participants-48% female and 36% Hispanic; mean age 8.9 years. Detailed analyses were performed for 162 children with respiratory disturbance indices < 1 and no parent-reported sleep problems. Mean and median reaction times (RT) decreased with increasing age (p trend < 0.001). Children ages 6 and 11 had median RTs of 544.24 and 325.70 ms, respectively. Standard deviations in RTs also decreased with increasing age (p trend = 0.001), as did lapses (p trend < 0.001), but no trend was apparent in total errors. There were statistically significant (p=0.006) differences in the performance of boys and girls. Gender differences were greatest at age 6, where boys had shorter RTs, and decreased with age until performance was approximately equal by age 11. No ethnic differences were detected. Children's PVT performance improves with age and differs by gender. These differences should be considered when the PVT is utilized in pediatric populations.
