PURPOSE: This study was designed to test the construct validity of a new medical app in the assessment of cognitive functioning. Specifically, this study compared the new medical app to an established, FDA-cleared, computer-based medical test known for its accuracy and reliability in assessing neurocognitive brain function. The new medical app has the potential to advance assessment due to its mobility as an app. METHODS: Data collection for this study is ongoing. To date, the study has collected data for 25 adult participants; however, the projected N is 100 participants. Assessments were administered in-person. Participants completed assessments on the new app (i.e., Impulse Control Assessment and Delayed Recall/Working Memory Assessment) followed by a similar battery assessing corresponding cognitive constructs in alternative ways (i.e., Word Memory, Design Memory Immediate, Word and Design Memory Delayed, Memory and Speed Assessment, Symbol Match, Color Match, and Three Letter Test). Comparisons were then made based on similarities in the constructs being assessed. RESULTS: Pearson’s r correlational analyses were used to determine the relationship between the scales of the new and more established cognitive assessments. Findings showed the new app demonstrated significant correlations with the established assessment’s Visual Motor Composite Scale, r = - 0.38, p = 0.015 and Reaction Time Composite Scale, r = 0.37, p = 0.018. Memory construct of new app’s Delayed Recall and Working Memory Assessment had no significant correlation with the established app’s memory scales (p > 0.05, respectively); however, a clinically relevant correlation, r = -0.24, p = 0.135 was demonstrated against the established assessment’s Symbol Match test. CONCLUSION: Despite being significantly underpowered the results of the correlations indicated significant associations between a new mobile cognitive assessment and several tests from an established assessment. A significant clinically meaningful correlation was found for the constructs of impulse control and reaction time. There were several other correlations that may indicate a possible significant finding with an increased N. These results support continued research to further investigate this assessment’s validity, and well as work to establish reliability.
