Age Trajectories of Perceptual Speed and Loneliness: Separating Between-Person and Within-Person Associations.

ABSTRACT:

Objectives

We aimed at examining between-person and within-person associations across age trajectories of perceptual speed and loneliness in old age.

Method

We applied multilevel models to 4 waves of data collected over 6 years from 1,491 participants of the Berlin Aging Study II (60-88 years at baseline, 50% women) to disentangle between-person and within-person associations across age trajectories of perceptual speed and both emotional and social loneliness. Sex and education were considered as relevant individual characteristics and included as covariates in the model.

Results

Analyses revealed that on average perceptual speed exhibited moderate within-person age-related declines, whereas facets of loneliness were rather stable. Perceptual speed did not predict age
