Abstract：
Web-based testing of cognitive abilities allows for large-scale assessments without geographical constraints. Yet, the extent to which it can reach populations beyond the typical demographic groups recruited for cognitive studies is unclear. This study focused on comparing the characteristics of individuals from a general population study (HUNT4) who chose to participate in a cognitive study (HUNT4-Hjernetrim) with those who did not. Additionally, we investigated participants\' engagement and user experience. We obtained data on socio-demographics, health conditions (both physical and mental), self-reported cognitive or learning difficulties, and lifestyle factors of Hjernetrim participants and non-participants from the HUNT4 database. Hjernetrim involved 13 cognitive tests, administered through the online platform Memoro. We used logistic regressions to assess participation biases and linear regressions to assess participants\' engagement and user experience. Of 65,851 HUNT4 participants invited via regular mail to Hjernetrim, 5634 (9.4%, aged 13-97, 54% women) participated. The best represented in the sample were 50-79-year-olds, women, tertiary educated, living alone, from urban areas, not occupationally active, and reporting memory complaints. Individuals who were aged 80+, had motor or vision impairments, and teenagers with learning disabilities, were underrepresented. Participants were more likely to have mental health problems, have or survived cancer and less likely to have cardiovascular disease. Participants logged on mainly during weekdays, the preferred time of day varied by age. On average, participants used 42 min and completed 78% of the tasks. Using PCs provided the most complete data. In terms of user experiences, 65% were positive while 14% were negative or reported technical difficulties. Overall, the study demonstrated that web-based methodology allowed for a relatively well-represented sample that included groups typically difficult to reach. The presence of somatic and mental diseases had a variable influence on participation. Participants finished most tests and reported positive experiences overall.
摘要：
基于Web的认知能力测试允许在没有地理限制的情况下进行大规模评估。然而，它能在多大程度上覆盖认知研究招募的典型人口学群体以外的人群,目前尚不清楚.这项研究的重点是比较选择参加认知研究（HUNT4-Hjernetrim）的一般人群研究（HUNT4）与未参加认知研究的个体的特征。此外,我们调查了参与者的参与度和用户体验。我们获得了社会人口统计数据，健康状况（身体和精神），自我报告的认知或学习困难，Hjernetrim参与者和非参与者的生活方式因素来自HUNT4数据库。Hjernetrim参与了13项认知测试，通过在线平台备忘录管理。我们使用逻辑回归来评估参与偏差，使用线性回归来评估参与者的参与度和用户体验。在通过常规邮件邀请Hjernetrim的65,851名HUNT4参与者中，5634（9.4%，13-97岁，54%女性）参加。样本中表现最好的是50-79岁的人，女人,受过高等教育，独自生活,从城市地区，不从事职业活动，并报告记忆投诉。80岁以上的人，有运动障碍或视力障碍，和有学习障碍的青少年，代表性不足。参与者更有可能有心理健康问题，患有癌症或幸存下来，不太可能患有心血管疾病。参与者主要在工作日登录，一天中的首选时间因年龄而异。平均而言,参与者使用了42分钟,完成了78%的任务.使用PC提供了最完整的数据。在用户体验方面,65%为阳性，14%为阴性或报告技术困难。总的来说,该研究表明,基于网络的方法可以得到一个相对良好的代表性样本,其中包括通常难以接触到的群体.躯体和精神疾病的存在对参与有不同的影响。参与者完成了大多数测试，并报告了总体积极的经历。
