Validating the On-line Creyos Cognitive Assessment Platform in Older Adults With Major Depressive Disorder or Mild Cognitive Impairment

Centre for Addiction and Mental Health150 enrolled

Overview

The goal of this observational study is to validate the Creyos online cognitive assessment platform in individuals with mild cognitive impairment, or remitted major depressive disorder. The main objectives of this research are: 1. To confirm the feasibility of administering the Creyos cognitive battery to older adults with Mild Cognitive Impairment MCI) or Major Depressive Disorder in remission (rMDD). 2. To determine whether the Creyos battery can detect changes in cognition that are predictive of changes on paper-and-pencil neuropsychological testing ("gold standard") over up to five years. Participants will complete both in-person neuropsychological testing yearly as well as the Creyos online battery quarterly for up to 5 years, to allow us to compare performance on these two batteries over time.

Outcomes

Primary Outcomes

Feasibility of Creyos Battery Administration

To determine the feasibility of administering the Creyos online cognitive platform in individuals with MCI and major depressive disorder in remission, participants will complete two questionnaires after every completion of the Creyos battery. Participants will be asked to complete the System Usability Scale (10 items). Scores on the System Usability Scale range from 0 to 100, with higher scores indicating greater usability. We will look at the total score to determine how easy the participants find the Creyos online cognitive platform to use, and if usability increases with exposure to the platform.

Time frame: Upon completion of the Creyos online cognitive platform, approximately every three months, for up to 5 years

Feasibility of the Creyos Battery

To determine the feasibility of administering the Creyos online cognitive platform in individuals with MCI and major depressive disorder in remission, participants will complete two questionnaires after every completion of the Creyos battery. Participants will be asked to complete the User Burden Scale (20 items). Scores on the User Burden Scale range from 0 to 80, with higher scores indicating greater user burden. We will look at the total score to determine how easy the participants find the Creyos online cognitive platform to use, and if usability increases with exposure to the platform.

Time frame: Upon completion of the Creyos online cognitive platform, approximately every three months, for up to 5 years

Validity of the Creyos Platform

To determine the validity of the Creyos online platform, we will compare the single test scores, domain composite scores and global composite scores between the in-person paper-and-pencil neuropsychological tests ("gold standard") and the Creyos online battery.

Time frame: In-person testing is completed yearly, and the Creyos online battery is complete quarterly, for up to 5 years
