In our third episode, we have two guests on the show: Maya Braun and Yong Zhang. Both are experts in measuring constructs that change over time and the challenges that come with that. We cover ambulatory assessment approaches for such constructs, how to deal with missing data and how to make your intensive longitudinal studies more engaging for participants.

If you want to better understand measurement of evolving constructs, this episode is for you!

In our second episode, we continue our conversation on Constructs with Gjalt-Jorn, GJ, Peters. We then move on to the measurement of these constructs and the difficulties in assessing the validity of our measurements. GJ introduces us to the idea of Narrative Response Models as a tool to link constructs to measurement instruments and assess their validity.

If you are unsatisfied with current ways to assess validity and want to think more deeply about the connection between what we want to measure and how we measure it, this episode is for you!

In our first guest episode, we talk with Annick De Paepe about why vague construct definitions stall science and how to fix this.

Topics include jingle–jangle pitfalls, pragmatic realism (and why multiple context-specific definitions can coexist), the Decentralised Construct Taxonomy, and a practical 4-step method for crafting definitions—illustrated with HAPA constructs (action planning, coping planning, self-efficacy, action control).

We hope that you leave with concrete steps to write and cite clearer definitions and how to link them to measurement.

Welcome to the first ever episode of the Define and Conquer Podcast. The podcast covers issues in theories, concepts, models and measurements that health psychologists face in their research.

We are your hosts, Olga Perski and Christoph Bamberg. Here, we briefly go through the exciting topics we will cover in the coming episodes. We will get help from experts from the European Health Psychology Special Interest Group Conceptualisation, Formalisation and Measurement to address these topics.

Stay tuned for the next episode - coming soon!
