Normative Data Guidance as of May 11, 2020
This document is guidance for health providers who are trained to deliver the BrainFx Virtual Cognitive Assessment (VCAx). The Virtual Cognitive Assessment is purpose-built to be delivered contactless or over video conferencing. Since it is a new assessment, the normative data continues to build and normative guidance will be released regularly. Below you will find the demographics of the normative sample as of the date above along with how the person was feeling at the time of assessment. For each cognitive skill that was assessed, you will find the distribution by version of the activity and the average performance and one standard deviation plus or minus from average. This guidance is to assist health providers in comparing their client’s performance to the normative group.
