Miami Prospective Memory Test in the Canadian Longitudinal Study on Aging

Area of Science:

• Cognitive Psychology
• Neuroscience
• Gerontology

Background:

• Prospective memory (PM) is crucial for daily functioning, involving remembering to perform intended actions in the future.
• The Canadian Longitudinal Study on Aging (CLSA) provides a large-scale dataset to investigate cognitive aging.
• The Miami Prospective Memory Test (MPMT) is a novel measure assessing event- and time-based prospective memory.

Purpose of the Study:

• To examine the influence of age, education, and sex on performance on the Miami Prospective Memory Test (MPMT).
• To analyze MPMT performance in neurologically healthy French- and English-speaking Canadian adults.
• To establish baseline data for future research and normative development of the MPMT.

Main Methods:

• Analysis of data from 18,511 participants (15,103 English-speaking, 3408 French-speaking) from the CLSA baseline.
• Participants were aged 45-85 years and screened for conditions affecting cognition.
• MPMT performance was assessed for intention, accuracy, and need for reminders, stratified by age and education.

Main Results:

• Significant effects of age were observed on event-based, time-based, and combined MPMT scores for both language groups.
• Education level significantly impacted all three MPMT scores in the English-speaking sample.
• The 'Intention to perform' score was most sensitive to age-related changes in both language groups; sex had no significant effect.

Conclusions:

• Age and education level are significant factors influencing performance on the MPMT.
• The findings support the utility of the MPMT as a measure of prospective memory in diverse populations.
• This study provides foundational data for developing normative values for the MPMT in English- and French-speaking Canadians.
