Working Memory

375
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Area of Science:

  • Neuroscience
  • Psychology
  • Clinical Medicine

Background:

  • Growing trend of individuals seeking medical help for cognitive symptoms.
  • Need for validated questionnaires in clinical evaluation.
  • Cognitive Function at Work Questionnaire (CFWQ) developed for working individuals' subjective cognitive symptoms.
  • Lack of psychometric validation of CFWQ in memory clinic settings.

Purpose of the Study:

  • To evaluate the psychometric properties of the CFWQ in a memory clinic setting.
  • To assess the factorial structure, internal consistency, test-retest reliability, and convergent validity of the CFWQ.
  • To investigate the CFWQ's ability to identify cognitive symptoms across different patient groups.

Main Methods:

  • Factor analysis to determine the factorial structure of the CFWQ.
  • Assessment of internal consistency using Cronbach's alpha.
  • Evaluation of test-retest reliability using the intraclass correlation coefficient (ICC).
  • Examination of convergent validity through correlations with neuropsychological impairment.
  • Study conducted in a memory clinic with 113 participants, including cohorts of early-onset dementia (EOD), mild cognitive impairment-neurological (MCI-n), MCI due to other causes (MCI-o), and subjective cognitive decline (SCD).

Main Results:

  • Factor analysis identified eight cognitive subscales: Memory, Language, Executive Function, Speed of Processing, Cognitive Control, Name Memory, Visuospatial/Praxis, and Attention.
  • High internal consistency (α = .93) and test-retest reliability (ICC = .91) were observed.
  • Significant correlations (r = .19 - .33, p < .05) found between CFWQ scores and neuropsychological impairment levels.
  • No statistically significant differences in overall CFWQ scores were found among EOD, MCI-n, MCI-o, and SCD groups.
  • The EOD group scored higher on the Visuospatial/Praxis subscale compared to other groups, though this finding was not significant after multiple testing correction.

Conclusions:

  • The CFWQ demonstrates strong validity and reliability in a memory clinic setting.
  • The questionnaire is user-friendly and clinically useful for identifying subjective cognitive symptoms in working patients.
  • The CFWQ aids in referring patients for more comprehensive cognitive evaluations.
