Objective To develop Chinese Toddler Sleep Assessment Scale (TSAS) suitable for Chinese toddles aged 13 - 35 months, and to evaluate the reliability, validity and feasibility of the scale, so as to provide an appropriate tool for assessing the sleep of Chinese children. Methods An item pool was established.The items were preliminary selected and modified through brainstorming, Delphi and pre-test.A total of 551 children aged 12 - 35 months in six communities, six towns and two sleep clinics were investigated from July to November 2019 using random sampling.Item analysis, validity analysis, reliability analysis, feasibility and confirmatory factor analysis were used to evaluate the scale. Results The TSAS had 20 items, including 6 factors of sleep rhythm,bedtime arrangement,night wakings, daytime sleepiness,parasomnias breathingand sleep disordered with total variance explained of 55.55%.The item-level content validity of all items ranged from 0.83 to 1.00.The scale was positively correlated with the Brief Infant Sleep Questionnaires in terms of sleep latency, number of night wakings and sleep duration (r=0.41, 0.69, 0.42, P<0.001).Except for daytime sleepiness, community sample scored lower than clinical sample in terms of the total score and other 5 factors (P<0.05).The total Cronbach's α coefficient was 0.72.The total retest reliability was 0.84.The completion rate of the scale was 92.6%.The results of confirmatory factor analysis showed that the factor structure model of TSAS was reasonable and stable. Conclusions TSAS have good reliability and validity, which could distinguish the sleep of toddlers in the community and clinics, and could be used for early screening of toddlers' sleep problems.
