Area of Science:

  • Neuroscience
  • Rehabilitation Medicine
  • Psychometrics

Background:

  • Cognitive impairment is common after stroke, necessitating reliable assessment tools.
  • The Montreal Cognitive Assessment (MoCA) is widely used, but its Taiwanese version (MoCA-T) requires validation for stroke populations.
  • Accurate cognitive assessment is crucial for effective stroke rehabilitation planning and monitoring.

Purpose of the Study:

  • To evaluate the relative and absolute reliability of the Taiwanese version of the MoCA (MoCA-T) in individuals post-stroke.
  • To determine the psychometric properties of the MoCA-T for use in stroke rehabilitation settings.
  • To establish the consistency and precision of MoCA-T scores over a 6-week interval.

Main Methods:

  • 114 participants, at least 3 months post-first-ever unilateral stroke, were recruited.
  • The MoCA-T was administered twice to all participants with a 6-week interval between assessments.
  • Relative reliability was assessed using the intraclass correlation coefficient (ICC), and absolute reliability using SEM, SRD, and Bland-Altman analysis.

Main Results:

  • The MoCA-T demonstrated high relative reliability, with an ICC of 0.85.
  • Absolute reliability measures, including SEM (1.38) and SRD (3.83), indicated acceptable to excellent levels of precision.
  • Bland-Altman analyses revealed no systematic bias and a narrow range of agreement, suggesting high stability over time.

Conclusions:

  • The Taiwanese version of the MoCA (MoCA-T) exhibits high reliability and stability for cognitive assessment in stroke patients.
  • The MoCA-T is a dependable tool for cognitive screening within stroke rehabilitation.
  • The established reliability thresholds support its use in detecting meaningful cognitive changes in this population.
