CogState是一种广泛使用的基于计算机的认知测试，其有效性尚未在资源贫乏的环境中得到解决。本研究探讨了CogState量表的结构、同时效度和聚合效度、重测信度以及社会人口学变量对学龄儿童CogState量表结果的影响。在基线和8周后，使用CogState、考夫曼儿童成套评估（第2版）（KABC-II）和注意力变量测试（TOVA）对230名平均年龄为6.99岁（SD = 1.67，范围5-13岁）的乌干达儿童（54%男性）进行评估。CogState与KABC-II和TOVA之间的相关性进行了分析，以评估其并发和收敛效度。采用因素分析法对CogState的结构效度进行评价。基线和8周CogState评分之间的相关性用于确定重测信度，而一般线性模型用于评估与社会人口因素的关联。CogState的一卡学习、一回记忆和卡片检测与TOVA之间以及CogState的迷宫追踪和一回记忆与KABC-Ⅱ的同时加工之间存在显著相关。CogState具有三因素结构，包括处理速度、处理准确性以及迷宫追逐和迷宫学习。CogState在乌干达儿童中的重测信度较低，相关系数为0.32至0.57。年龄、性别和教育与CogState结果相关。CogState是乌干达儿童基于计算机的神经认知快速评估的有效和可靠的测试电池，因此可以在这种文化背景下使用。本文的在线版本（doi：10.1186/s13034-015-0063-6）包含补充材料，可供授权用户使用。
CogState is a widely used computer-based cognitive test whose validity has not been addressed in resource poor settings. We examined the construct, concurrent and convergent validity of CogState, test–retest reliability and the effect of sociodemographic variables on CogState outcomes in school age children. Two hundred and thirty Ugandan children (54% male) with mean age 6.99 years (SD = 1.67, range 5–13 years) were assessed using CogState, the Kaufman Assessment Battery for Children, 2nd edition (KABC-II) and the Test of Variables of Attention (TOVA) at baseline and 8 weeks later. Correlations were run between CogState and the KABC-II and TOVA to evaluate its concurrent and convergent validity. Factor analysis was used to evaluate construct validity of CogState. Correlations between baseline and 8 weeks CogState scores were used to determine the test–retest reliability while general linear models were used to assess associations with sociodemographic factors. Significant correlations were observed between CogState’s One Card Learning, One Back Memory and Card Detection with the TOVA and between CogState’s Maze Chase and One Back Memory with KABC-II’s Simultaneous Processing. CogState had a three factor structure with Processing Speed, Processing Accuracy and Maze Chase and Maze Learning. CogState had low to moderate test–retest reliability in Ugandan children with correlations ranging from 0.32 to 0.57. Age, sex and education were associated with CogState outcomes. CogState is a valid and reliable test battery for rapid computer-based neurocognitive assessment in Ugandan children and can thus be used in this cultural context.
