Construct Validity and Test‐Retest Reliability of the Digital Brain Function Screen (DBFS) for Early Cognitive Impairment

The study confirms that DBFS domains effectively measure the intended cognitive constructs and maintain high reliability across repeated administrations. These findings establish the validity and reliability of DBFS as a practical, scalable, and efficient tool for detecting and monitoring early cognitive impairment. Its usability makes it suitable for deployment in various healthcare settings, including screening centers and specialty clinics.
