Scientific Reports - Rethinking psychometrics through LLMs: how item semantics shape measurement and prediction in psychological questionnaires

Interested in mastering intensive longitudinal methods for your dissertation or research program? Join Professor Scott Colwell (University of Guelph; Enablytics) for a two-day intensive, hands-on workshop that takes you from raw diary/ESM/EMA data to publication-ready models and APA-style reporting using Mplus and R/RStudio. Designed for PhD students, academic researchers, and applied scientists, the seminar covers data wrangling and visualization, centering and variance decomposition, multilevel random intercepts/slopes, lagged and dynamic models (VAR/DSEM), moderation, within-person mediation, principled missing-data methods, simulation-based power analyses, and reproducible reporting templates—plus live troubleshooting, code, and exemplars you can adapt immediately. Sessions are livestreamed via Zoom with 30-day access to recordings, materials, and a monitored Q&A forum; participants receive example data, Mplus input and R scripts, and a certificate of completion (ECTS-equivalent where indicated). Register to build the practical skills needed to design diary studies, implement advanced longitudinal analyses, diagnose estimation issues, and produce transparent, reproducible pipelines for theses, grants, and journal papers. #ConsumerResearch #DataAnalytics #Epidemiology #LongitudinalDataAnalysis #Management #Psychology #Psychometrics #PublicHealth #Statisticalmodellingandregression #Statistics #Education #DataScience #Biostatistics #R #RStudio #Research #ResearchTraining #Instats

The estimation of the correct number of dimensions is a long-standing problem in psychometrics. Several methods have been proposed, such as parallel analysis (PA), Kaiser-Guttman’s eigenvalue-greater-...

Exploratory graph analysis (EGA) is a new technique that was recently proposed within the framework of network psychometrics to estimate the number of factors underlying multivariate data. Unlike other methods, EGA produces a visual guide-network plot-that not only indicates the number of dimensions …

Many socially consequential beliefs, notably political and religious ideologies, consist not of single propositions in isolation from others but as systems of many propositions. Philip Converse, one o...
