Canadian Longitudinal Study on Aging releases cognition data for 51,000 participants

Published: February 27, 2017

Cognition data collected at baseline on 51,000 participants in the Canadian Longitudinal Study on Aging (CLSA) are now available for access by researchers.

The CLSA is a large, national research platform on health and aging that allows researchers and decision-makers to answer critical questions on the biological, medical, psychological, social, lifestyle and economic aspects of aging, disability and disease. The CLSA follows approximately 51,000 men and women who were between the ages of 45 and 85 at recruitment, for 20 years. Through its large sample, detailed data collection and longitudinal design, the CLSA will enable research on the complex interplay among health determinants.

The cognitive measures available include:

  • The Rey Auditory Verbal Learning Test – Trial 1 and five-minute delayed recall; Animal Fluency, the Mental Alternation Test (available for all participants);
  • Controlled Oral Word Association Test, Stroop Test, Prospective Memory Test and Choice Reaction Time (available for 30,000 participants).

These baseline cognition data include raw data, test scores and metadata indicating the quality of recordings and any anomalies noted for the measures.

Please consult the CLSA website for the application process and submission deadlinespolicies and procedures and the CLSA protocol. Detailed descriptions of the CLSA cognitive measures are available here. Summary statistics for individual variables can be viewed through the CLSA DataPreview Portal
