Abstract

Background: Traditional cognitive assessments, often reliant on paper-and-pencil tests and professional evaluators, suffer from subjectivity and limited result discrimination. This study introduces the Baguan Online Cognitive Assessment System (BOCAS), a tablet-based system that evaluates both general cognitive ability (GCA) and domain-specific functions across six domains: sensory-motor skills, processing speed, sustained attention, working memory, cognitive flexibility, and spatial ability.

Methods: BOCAS was validated with 151 healthy Chinese adults aged 18-40. Reliability was assessed through internal consistency and test-retest reliability. Factor analysis and confirmatory factor analysis (CFA) were used to validate the model. The GCA score was correlated with the Raven IQ test and self-reported cognitive flexibility, and its relationship with negative emotions (depression and anxiety) was examined.

Results: BOCAS showed satisfactory reliability, with internal consistency ranging from 0.712 to 0.846 and test-retest reliability from 0.56 to 0.71. Factor analysis revealed a common factor explaining 40% of the variance, and CFA indicated a good model fit (χ²/df = 1.81; CFI = 0.932). The GCA score strongly correlated with the Raven IQ test (r = 0.58) and was related to self-reported cognitive flexibility and negative emotions.

Conclusion: BOCAS offers a digital solution for cognitive assessment, providing automated, remote, and precise evaluations. It demonstrates reliability, validity, and potential for use in clinical and research settings.

基于片剂的一般认知能力评估电池的开发与验证。

背景：传统的认知评估往往依赖于纸笔测试和专业评估人员，存在主观性和有限的结果歧视。本研究介绍了八关在线认知评估系统（BOCAS），这是一个基于平板电脑的系统，可以评估一般认知能力（GCA）和特定领域的功能，包括六个领域：感觉-运动技能、处理速度、持续注意力、工作记忆、认知灵活性和空间能力。方法：对151名18-40岁的中国健康成年人进行BOCAS验证。信度通过内部一致性和重测信度进行评估。采用因子分析和验证性因子分析（CFA）对模型进行验证。GCA得分与Raven IQ测试和自我报告的认知灵活性相关，并与负面情绪（抑郁和焦虑）相关。结果：BOCAS具有良好的信度，内部一致性为0.712 ~ 0.846，重测信度为0.56 ~ 0.71。因子分析显示一个共同因子解释了40%的方差，CFA表明模型拟合良好(χ²/df = 1.81；cfi = 0.932)。GCA得分与Raven IQ测试呈强相关（r = 0.58），并与自我报告的认知灵活性和负面情绪相关。结论：BOCAS为认知评估提供了数字化解决方案，可提供自动化、远程和精确的评估。它证明了在临床和研究环境中使用的可靠性、有效性和潜力。
