Predictors of subjective age before and after cataract surgery: conscientiousness makes a difference

Area of Science:

• Gerontology
• Psychology
• Health Sciences

Background:

• Subjective age, or felt age, is a key aspect of psychological well-being in later life.
• Understanding factors influencing felt age is crucial for promoting healthy aging.

Purpose of the Study:

• To investigate the relationship between felt age, health indicators, functional limitations, and personality traits.
• To explore how conscientiousness moderates the impact of health and functional limitations on felt age.

Main Methods:

• Longitudinal study of 134 individuals (38-92 years) undergoing cataract surgery.
• Data collected over a 6-week period around surgery, including health indicators, functional limitations, and felt age.
• Analysis focused on the interplay of personality (conscientiousness) and health-related factors in shaping subjective age.

Main Results:

• Functional limitations were more strongly associated with felt age than underlying health conditions.
• Participants with higher conscientiousness reported feeling younger both before and after surgery.
• Conscientiousness moderated the relationship between health and functional status, making it less health-dependent for conscientious individuals.

Conclusions:

• Functional limitations play a significant role in the construction of subjective age.
• Personality traits, specifically conscientiousness, can buffer the impact of health on perceived age and functional status.
• These findings highlight the complex interplay between health, function, personality, and subjective age in the aging process.
