Longitudinal Associations Between Psychological Resilience and Cognitive Function: Evidence From the U.S. Health and...

Area of Science:

• Gerontology
• Cognitive Science
• Psychology

Background:

• Cognitive decline and reduced psychological resilience are prevalent in older adults.
• Understanding their longitudinal relationship is crucial for targeted interventions.
• This study examines the interplay between cognition and resilience over time.

Purpose of the Study:

• To evaluate the longitudinal associations between cognitive function and psychological resilience.
• To investigate the bidirectional relationship between these two factors in older adults.
• To inform interventions aimed at promoting healthy aging.

Main Methods:

• Utilized data from 9,075 U.S. adults aged 65+ from the Health and Retirement Study (2006-2020).
• Cognition assessed via a modified Telephone Interview Cognitive Screen.
• Psychological resilience measured using a simplified resilience score.
• Bivariate latent growth modeling analyzed parallel changes over up to 12 years.

Main Results:

• Significant positive correlations were found between the initial levels (intercepts) and rates of change (slopes) of psychological resilience and cognition.
• Higher initial cognitive function predicted greater increases in psychological resilience over time.
• Initial psychological resilience also positively predicted changes in cognitive function, though to a lesser extent.

Conclusions:

• Cognition and psychological resilience demonstrate a mutually reinforcing relationship in older adults.
• Interventions promoting cognitive function may enhance psychological resilience.
• Findings support integrated approaches to maintaining cognitive and psychological health in aging populations.
