Time-Varying Effect Models for Examining Age-Dynamic Associations in Gerontological Research.

ABSTRACT:

Objectives

Dynamic processes unfolding over later adulthood are of prime interest to gerontological researchers. Time-varying effect modeling (TVEM) accommodates dynamic change trajectories, but its use in gerontological research is limited. We introduce and demonstrate TVEM with an empirical example based on the National Health and Aging Trends Study (NHATS).

Methods

We examined (a) age-varying prevalence of past month elevated symptoms of depression and anxiety and (b) age-varying associations between older adults' elevated symptoms of depression and anxiety and needing help with basic activities of daily living and educational attainment.

Results

The proportion of participants reporting elevated symptoms of depression and anxiety in the past month increased gradual
