More than Counting: An Intraindividual Variability Approach to Categorical Repeated Measures.

ABSTRACT:

Objectives

Age-related differences in daily experiences are often described using summaries of categorical repeated measures, including typologies of stressors, activities, social partners, and coping strategies. This paper illustrates how an intraindividual variability (IIV) framework can be used to extract additional meaning from categorical IIV data.

Method

Using 8-occasion categorical data on daily stressors from the National Study of Daily Experiences (N = 1,499, MAge = 46.74, SDAge= 12.91), we derive and compute six IIV metrics that invoke numeric and nominal measurement of the central tendency, dispersion, and asymmetry of individuals' stressor experiences and examine how these metrics, relative dominance, diversity, log-skew and mode, spread, order, are related to ag
