To explore the association between the user's cognitive function and usability reported by the evaluator. A cross-sectional study was conducted with a community-based sample. Data about participants' age, sex, education, sleep quantity, subjective memory complaints, and cognitive function were collected. A usability session was conducted to evaluate a digital solution called Brain on Track. Independent linear-regression analyses were used to explore univariable and multivariable associations between evaluator-reported usability assessment and the users' cognitive function, age, sex, education, sleep quantity, and subjective memory complaints. A total of 238 participants entered this study, of which 161 (67.6%) were females and the mean age was 42 (SD 12.9) years old. All variables (age, education, sleep quantity, subjective memory complaints and cognitive function) except sex were significantly associated with evaluator-reported usability in the univariable analysis (p < 0.05). Cognitive function, age, education, and subjective memory complaints remained significant in the multivariable model (F = 38.87, p < 0.001) with an adjusted R2 of 0.391. Cognition scores alone showed an adjusted R of 0.288. This work suggests that cognitive function impacts evaluator reported usability, alongside other users' characteristics and needs to be considered in the usability evaluation.
探索用户认知功能与评估者报告的可用性之间的关联。本研究采用基于社区的样本进行了横断面研究。收集了参与者的年龄、性别、教育程度、睡眠量、主观记忆抱怨和认知功能等数据。进行了一次可用性会话，以评估名为“Brain on Track”的数字解决方案。使用独立线性回归分析探索评估者报告的可用性评估与用户认知功能、年龄、性别、教育程度、睡眠量和主观记忆抱怨之间的单变量和多变量关联。共有 238 名参与者进入了这项研究，其中 161 名（67.6%）为女性，平均年龄为 42 岁（标准差 12.9 岁）。除性别外，所有变量（年龄、教育程度、睡眠量、主观记忆抱怨和认知功能）在单变量分析中均与评估者报告的可用性显著相关（p<0.05）。在多变量模型中，认知功能、年龄、教育程度和主观记忆抱怨仍然具有统计学意义（F=38.87，p<0.001），调整后的 R2 为 0.391。仅认知功能评分的调整 R 为 0.288。这项工作表明，认知功能会影响评估者报告的可用性，以及其他用户的特点和需求，在可用性评估中需要考虑这些因素。
