Summary
This study clarifies that the Digital Clock and Recall (DCR) and Cognivue Clarity assessments used the same participants, refuting claims of nonequivalent cohorts. Head-to-head comparisons support digital cognitive assessment standards.
Area of Science:
- Neuroscience
- Cognitive Science
- Biomedical Engineering
Background:
- Cognitive assessment tools are crucial for early detection of neurodegenerative diseases.
- Digital cognitive assessments offer novel approaches to evaluating cognitive function.
- Clarification is needed regarding the methodology of comparative studies in digital cognitive assessment.

01:29Reliability and Validity
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
