在预期功能下降或恢复的情况下，需要进行系列评估。然而，由于缺乏文化上适当的评估，缺乏适合重复管理的心理测量特性，对土著人口的认知进行系列评估可能会有问题。这项研究评估了非语言、文化中立、计算机化认知测试组合的重测可靠性和对40名健康土著青少年（平均年龄15.25岁）样本的任何实践效果。没有实践效果和足够的重测可靠性记录的准确性和速度的测试的心理功能，视觉注意力和工作记忆（即卡片任务）。在更复杂的学习和记忆任务（即非卡片任务）中，也观察到准确性（但不是速度）缺乏练习效果和足够的可靠性。有趣的是，这一结果与类似研究的结果形成鲜明对比，在这些研究中，非土著人在相同任务上的表现表明速度比准确性更可靠，这可能反映了这些群体之间对时间的不同看法。在土著青少年中，这项研究表明，所选择的认知评估过程具有可接受的可靠性和稳定性，为在这一人群中作为研究和筛选工具提供了有效性。
Serial assessment is required in situations where decline or recovery of function is anticipated. Serial assessment of cognition in Indigenous populations, however, can be problematic due to a lack of culturally appropriate assessments with psychometric properties suitable for repeated administration. This study assessed a non-verbal, culturally neutral, computerised cognitive test battery for its test-retest reliability and any practice effects in a sample of 40 healthy Indigenous adolescents (mean age 15.25 years). No practice effects and adequate retest reliabilities were recorded for both accuracy and speed on tests of psychomotor function, visual attention and working memory (i.e. card tasks). A lack of practice effects and adequate reliabilities were also observed for accuracy (but not speed) on the more complex learning and memory tasks (i.e. non-card tasks). Interestingly, this outcome contrasts with those of similar studies in which the performance of non-Indigenous people on the same tasks showed speed to be a more reliable measure than accuracy, and this may reflect different perceptions of time between these groups. Among Indigenous adolescents, this study demonstrates acceptable reliability and stability of the selected cognitive assessment process, providing validity for its use as a research and screening tool in this population.
