Retrospective data collected on SATURN, a public domain self-administered cognitive screening test

Neurocognitive disorders are under-diagnosed. A previously validated
public domain cognitive screening test, Self-Administered Tasks Uncovering
Risk of Neurodegeneration (SATURN), may address this need. However, there
are no prior reports of its performance in its intended clinical settings.
From a single dementia clinic, we retrospectively collected and analysed
scores on SATURN, the Montreal Cognitive Assessment (MoCA), Mini-Mental
State Examination (MMSE), Saint Louis University Mental Status (SLUMS),
and the Functional Activities Questionnaire (FAQ), obtained over a
two-year period. We found that SATURN was well-correlated with each of the
other assessments (MoCA: r = 0.82, MMSE: r = 0.76, SLUMS: r = 0.81, and
FAQ: r = -0.55). In receiver operating characteristic (ROC) analyses,
SATURN was statistically non-inferior to those other tests, and indeed was
usually numerically (but not statistically) superior. In short, SATURN
compared favorably to legacy cognitive screening instruments in regular
clinical practice.
