CAMeL (Community for Advanced Methodological Learning)

What is CAMeL: CAMeL is a student-run group based in the Psychology department, focused on broadening and deepening our knowledge about advanced quantitative methodology. (Faculty mentor: Aidan Wright, Ph.D.)

Who is CAMeL: We encourage scholars of all levels (including students, post-docs, staff, and faculty) and departments to join and contribute as often as desired.

Contact: Please feel free to contact Aidan Wright (, Catie Walsh (, or Molly Bowdring ( with any questions! If you have an area of methodological interest or expertise on which you’d like to present, we’d love to hear from you!

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

ABSTRACT: Experience sampling studies often collect categorical repeated measures, including stressor types, activity types, and social partner types. Such variables are often analyzed as raw frequency counts, aggregate sums, or collapsed binary indicators. This presentation will illustrate how an intraindividual variability (IIV) framework can be used to interpret categorical repeated measures data. Specifically, I compute six IIV metrics using both numeric and nominal aspects of the data, using daily stressor type data as an illustrative example. I demonstrate how these novel metrics of IIV can be mapped to theory and related to age and interindividual differences in health and well-being. Findings highlight categorical IIV metrics may be used to examine dynamic process, study interindividual and age-related differences, and expand the variety of research questions that may be answered using categorical data.
