Advances in perinatal and neonatal care have substantially improved the survival of at-risk infants over the past two decades.
The purpose of this study was to assess the reliability and validity of the Bayley Scales of infant and toddler developmental Screening test in Persian-speaking children.
This was a cross-sectional prospective study of 403 children aged 1 - 42-months. The Bayley scales screening instrument, which consists of five domains (cognitive, receptive, and expressive communication and fine and gross motor items), was used to measure infants' and toddlers' development. The psychometric properties examined included the face and content validity of the scale, in addition to cultural and linguistic modifications to the scale and its test-retest and inter-rater reliability.
An expert team changed some of the test items relating to cultural and linguistic issues. In almost all the age groups, cultural or linguistic changes were made to items in the communication domains. According to Cronbach's alpha for internal consistency, the reliability of the cognitive scale was r = 0.79, and the reliability of the receptive scale was r = 0.76. The reliability for expressive communication, fine motor, and gross motor scales was r = 0.81, r = 0.80, and r = 0.81, respectively. The construct validity of the tests was confirmed using a factor analysis and comparison of the mean scores of the age groups. The intra- and inter-rater reliabilities of the Bayley Scales were good-to-excellent.
The results indicated that the Bayley Scales had a high level of reliability in the present study. Thus, the scale can be used in a Persian population.

本研究的目的是评估贝利婴幼儿发展筛查测验在说波斯语儿童中的信度和效度。
这是一项对403名年龄在1至42个月儿童的横断面前瞻性研究。贝利量表筛查工具由五个领域（认知、接受性、表达性沟通以及精细和粗大运动项目）组成，用于测量婴幼儿的发育情况。除了对量表进行文化和语言修改及其重测信度和评分者间信度外，所检验的心理测量特性还包括量表的表面效度和内容效度。
一个专家团队对一些与文化和语言问题相关的测试项目进行了修改。在几乎所有年龄组中，对沟通领域的项目进行了文化或语言方面的修改。根据内部一致性的Cronbach's alpha系数，认知量表的信度为r = 0.79，接受性量表信度为r = 0.76。表达性沟通、精细运动和粗大运动量表的信度分别为r = 0.81、r = 正确的是0.80和r = 0.81。通过因素分析和年龄组平均得分比较证实了测试的结构效度。贝利量表的评分者内信度和评分者间信度良好至优秀。
结果表明，在本研究中贝利量表具有较高的信度。因此，该量表可用于波斯人群。
