The Bayley Scales of Infant and Toddler Development, 3rd Edition (Bayley-III) is frequently used in international child development research. No studies examine its psychometric properties when culturally adapted within the Kenyan context.
To culturally adapt the Bayley-III for use in Kenya and evaluate its validity and reliability.
Forward and backward translation, cognitive interviews, and a brief pilot of culturally adapted items were performed. This psychometric study was part of another study on children born to mothers with HIV in Eldoret, Kenya. One hundred seventy-two children aged 18-36 months were assessed for cognition, receptive/expressive communication, and fine/gross motor domains using the Bayley-III. Confirmatory factor analysis (CFA), inter-scale Pearson correlations, internal consistency, t-tests, and test-retest reliability were performed.
The mean age of children was 22.8 (SD 4.5) months old; 52.7 % (n = 89) were male. CFA revealed that both two- and three-factor indices had good and comparable fit. Pearson correlations were high between fine motor and receptive communication (r >0.70). Internal consistency was very strong for all of the subtests, with Cronbach coefficient alpha scores ranging from 0.88 to 0.96. Known groups/convergent validity was confirmed with stunting and parental concern for delays. Test-retest reliability was good and did not differ substantially across groups.
The Kenyan adapted Bayley-III is a psychometrically acceptable tool to assess child development. The scaled and composite scores should not be used to define Kenyan developmental norms, but it can be useful for comparing groups within research settings.
《贝利婴幼儿发展量表》第三版（Bayley-III）在国际儿童发展研究中经常被使用。尚无研究考察其在肯尼亚文化背景下进行文化调适后的心理测量特性。
对Bayley-III进行文化调适以便在肯尼亚使用，并评估其效度和信度。
进行了正向和反向翻译、认知访谈以及对文化调适后的项目进行简短预试。这项心理测量研究是另一项关于肯尼亚埃尔多雷特感染艾滋病毒母亲所生孩子的研究的一部分。使用Bayley-III对172名18至36个月大的儿童进行了认知、接受性/表达性沟通以及精细/粗大运动领域的评估。进行了验证性因素分析（CFA）、量表间皮尔逊相关性分析、内部一致性分析、t检验以及重测信度分析。
儿童的平均年龄为22.8（标准差4.5）个月；52.7%（n = 89）为男性。CFA显示二因素和三因素指标均具有良好且可比的拟合度。精细运动与接受性沟通之间的皮尔逊相关性较高（r > 0.70）。所有子测验的内部一致性都很强，克朗巴赫系数α得分在0.88至0.96之间。通过发育迟缓情况和家长对发育延迟的担忧证实了已知群体/收敛效度。重测信度良好，且不同群体间差异不大。
肯尼亚调适版Bayley-III是一种在心理测量方面可接受的评估儿童发展的工具。量表得分和综合得分不应被用于定义肯尼亚的发育规范，但在研究环境中比较不同群体时可能会有用。
