This poster presented at the ISOQOL 2025 annual meeting reviews a targeted literature that examined how Intraclass Correlation Coefficients (ICCs) are used in multilevel modeling of intensively collected questionnaire data through clinical outcome assessments (COA), daily diaries, and digital health measures. The findings highlight the importance of modeling both within- and between-person variability and call for standardized reporting to improve transparency and comparability in future research.Listen now to Dara O’Neill as she provides an overview of the poster and key takeaways.
