Reliability and Validity

13.2K
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.

Area of Science:

  • Cognitive Neuroscience
  • Gerontology
  • Psychometrics

Background:

  • Executive function, including planning and inhibitory control, declines with age.
  • Executive dysfunction impacts daily living activities in older adults.

Purpose of the Study:

  • To assess the validity of a computerized cognitive assessment, Freeze Frame, for predicting executive function in healthy older adults.
  • To provide normative data for cognitively healthy older adults aged 65 and above.

Main Methods:

  • Retrospective analysis of baseline data from the INHANCE trial.
  • Evaluation of Freeze Frame (BrainHQ platform) usability and validity.
  • Analysis of Freeze Frame performance against demographic variables and NIH EXAMINER executive function scores.

Main Results:

  • Freeze Frame performance was modestly associated with NIH EXAMINER executive function scores (P=.02), explaining 6.8% of the variance.
  • A small, statistically significant relationship was found between Freeze Frame and age (P=.046).
  • The assessment demonstrated good usability with an average completion time of 4 minutes.

Conclusions:

  • Freeze Frame is a brief, scalable, and accessible computerized cognitive assessment with demonstrated concurrent validity for executive function.
  • Its ease of use suggests potential for cognitive screening in older adults.
  • Future research should investigate its utility in clinical populations and for predicting functional performance.
