The Roles of Age and Depression in Affective Responsivity to Daily Positive Events.

Area of Science:

• Gerontology
• Psychology
• Mental Health

Background:

• Depression significantly impacts adult daily functioning.
• Aging involves emotion regulation (ER) strengths and physiological challenges influencing depression.
• Affective responsivity, including mood brightening (MB), may indicate ER disturbances in depression.

Purpose of the Study:

• To examine age-related patterns in MB.
• To investigate cross-sectional age differences and longitudinal changes in MB.
• To assess MB in relation to depression across the adult lifespan.

Main Methods:

• Utilized data from the Midlife in the United States Study and National Study of Daily Experiences (Waves 2 & 3).
• Analyzed data from 2,022 participants (ages 35-86, 10.63% screened positive for depression).
• Employed multilevel models to assess age patterns in MB over 8 days, ~10 years apart, controlling for covariates.

Main Results:

• MB was amplified in older adults; depressed older adults showed greater positive affect responsivity to positive events than younger adults.
• The magnitude of MB decreased over the 10-year follow-up period.
• This decline was more pronounced in comparatively older adults within the sample.

Conclusions:

• Older adults, especially those with depression, exhibit distinct affective responsivity patterns.
• The diminishing MB over time may serve as an early daily marker for depression risk.
• Findings support the need for personalized, age-inclusive healthcare strategies for depression.
