Area of Science:

  • Cognitive Neuroscience
  • Gerontology
  • Psychometric Assessment

Background:

  • The Trail Making Test (TMT) is a widely used neuropsychological tool to assess cognitive function.
  • Traditional paper-based TMT lacks the granularity to precisely identify underlying cognitive processes.
  • Digital adaptations offer potential for more detailed data collection and analysis.

Purpose of the Study:

  • To introduce and validate a newly developed digital tablet-based variant of the TMT (dTMT).
  • To isolate specific component cognitive processes contributing to TMT performance.
  • To examine the relationship between dTMT component scores and traditional neuropsychological measures.

Main Methods:

  • Development of a digital TMT (dTMT) recording detailed performance metrics beyond completion time and errors.
  • Administration of the dTMT and traditional neuropsychological tests to community-dwelling older adults.
  • Regression analyses to correlate dTMT component scores with measures of processing speed, inhibitory control, and sequencing.

Main Results:

  • High correlations were found between the paper-based TMT and the dTMT for both Part A and Part B.
  • Processing speed significantly predicted dTMT Part A performance.
  • Inhibitory control and visual/spatial sequencing were key predictors for specific components of dTMT Part B.
  • Exploratory findings linked dTMT-B components to medication management task performance.

Conclusions:

  • The dTMT is a valid and reliable tool for assessing cognitive abilities in older adults.
  • The digital format allows for the isolation and detailed analysis of specific cognitive components underlying TMT performance.
  • This enhanced understanding of cognitive processes can inform targeted interventions and assessments.
