“…Despite the narrow age range covered in this study, we found that SATURN scores correlated with age and education, as expected in cognitive screening tests (Ardila et al, 2000); no gender-related differences were evident. We found that time-of-day had no impact on SATURN scores: this is an important source of variability that we cannot control for when the test is performed remotely but could impact performance in both healthy and clinical populations (Blatter & Cajochen, 2007; Singh et al, 2016; Wilks et al, 2021).…”

Feasibility of Remote Unsupervised Cognitive Screening With SATURN in Older Adults

et al. 2023

Widespread cognitive test screening as part of tele-public health initiatives necessitates a test that is self-administered online and automatically scored, with no clinician effort. The feasibility of unsupervised cognitive screening is unclear. We adapted the Self-Administered Tasks Uncovering Risk of Neurodegeneration (SATURN) to make it suitable for self-administration and automatic scoring. 364 healthy older adults completed SATURN via a web browser, in a fully independent manner. SATURN’s overall score was not modulated by gender, education, reading speed, the time of day at which the test was taken, or an individual’s familiarity with technology. SATURN proved extremely portable across operating systems. Importantly, comments from participants reported satisfaction with the experience and the clarity of the instructions. SATURN represents a fast and easy screening tool that can be used for a first assessment, during a routine test or clinical evaluation, or during periodic health monitoring, in person or remotely.
