Validation of SATURN; an Inexpensive, Freely-available, and Fully Self-administered Cognitive Screening Test.

Objective: To develop and validate a free, public domain, automatically scored, and self-administered cognitive screening test. Background: Cognitive screening tests improve detection of dementia in the outpatient setting, and are helpful in select inpatient settings. Barriers to widespread screening include provider time investment and training (for test administration and scoring). We therefore developed Self-Administered Tasks Uncovering Risk of Neurodegeneration (SATURN) for inexpensive ( Design/Methods: SATURN is a thirty-point test including orientation, word recall, and math items adapted from the Saint Louis University Mental Status test, modified versions of the Stroop and Trails tasks, and other assessments of visuospatial function and memory. We recruited English-speaking neurology clinic patients and their partners aged 50–89 years. After taking SATURN and the Montreal Cognitive Assessment (MoCA), participants answered a brief survey including demographics and test preferences. For patients recruited from dementia clinics (n=17), clinical status was quantified with the clinical dementia rating scale (CDR), and compared to SATURN and MoCA scores (for care partners, CDR=0). SATURN and the MoCA were also compared to one-another. Results: Twenty-four patient-partner dyads (n=47) were recruited. Four patients with moderate-to-severe dementia (CDRglobal ≥ 2.0) were not scorable based on pre-defined reading proficiency criteria. For the remaining (n=43) participants, (52% women; age (mean±sd) 65.9±9.8 years) SATURN and MoCA scores were highly correlated (r=0.90; p Conclusions: SATURN is a freely available (https://doi.org/10.5061/dryad.02v6wwpzr) and fully self-administered cognitive screening test. Since it performs well compared to CDR ratings and MoCA scores in patients who can read, it may enjoy widespread use. Disclosure: Dr. Bissig has nothing to disclose.
