Innovations in psychometric modelling: New approaches to understanding psychological measurement
- Giorgia Tosi (University of Milan-Bicocca)
This symposium highlights innovative approaches to psychometric modelling aimed at advancing the assessment and understanding of psychological constructs. The four contributions showcase diverse methodologies that go beyond traditional frameworks to better capture the complexity of human behaviour and measurement.
The first presentation evaluates the use of Exploratory Graph Analysis (EGA)...
In psychological research, measurement models often aggregate items under the assumption that the effects of other variables remain consistent across those items (i.e., effect invariance). This assumption can lead to biased statistical conclusions, particularly by producing a positive bias in the F-test and inflating the Type I error rate, since it overlooks the random variability in...
The Rasch model is a widely used psychometric model that enables the direct comparison between item properties and respondent characteristics. However, its strict assumptions can limit its applicability in experimental psychology. Given its mathematical equivalence to the inverse logit link function in generalized linear models (GLMs) for binomially distributed response variables, Rasch-like...
Background: Discriminant validity (DV) is present when two measures of similar, yet distinct constructs exhibit a correlation that is sufficiently low to consider them as distinct. Multiple strategies exist for evaluating DV, but recent recommendations highlighted Structural Equation Modeling (SEM) as a robust approach, although contemporary techniques such as Exploratory Graph Analysis...
Italian students have consistently underperformed in international mathematics assessments. Thus, innovative approaches to support learning in this domain are necessary. Educational games, which incorporate game-like elements into learning and assessment, have emerged as promising tools for enhancing students’ engagement and improving learning outcomes. Moreover, affective components and...
