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.
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.
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.
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.
传统的认知评估通常依赖纸笔测试和专业评估人员，存在主观性且结果区分能力有限。本研究引入了八观在线认知评估系统（BOCAS），这是一种基于平板电脑的系统，可评估一般认知能力（GCA）以及六个领域的特定领域功能：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。
BOCAS在151名年龄在18至40岁之间的健康中国成年人中进行了验证。通过内部一致性和重测信度评估可靠性。使用因子分析和验证性因子分析（CFA）来验证模型。将GCA分数与瑞文智商测试以及自我报告的认知灵活性相关联，并检验其与负面情绪（抑郁和焦虑）的关系。
BOCAS显示出令人满意的可靠性，内部一致性范围为0.712至0.846，重测信度为0.56至0.71。因子分析揭示了一个共同因子，解释了40%的方差，CFA表明模型拟合良好（χ²/df = 1.81；CFI = 0.932）。GCA分数与瑞文智商测试高度相关（r = 0.58），并与自我报告的认知灵活性和负面情绪有关。
BOCAS为认知评估提供了一种数字解决方案，提供自动化、远程和精确的评估。它展示了在临床和研究环境中使用的可靠性、有效性和潜力。
