Alberto Filgueiras is a Brazilian Researcher with Bachelor in Psychology at Federal University of Rio de Janeiro (UFRJ), Brazil; and Master of Arts (M.A.) in Psychometrics at Pontifical Catholic University of Rio de Janeiro (PUC-Rio), Brazil. His current position is as a PhD Student at Pontifical Catholic University of Rio de Janeiro (PUC-Rio), Brazil. His main interests are Applied Research and Quantitative Methods in Psychometrics and Psychophysics, focused in Experimental Psychology, Structural Modeling, Item Response Theory, Multilevel Statistics and Behavior Modeling.

Current Researchs




Psychological Measurement - Measuring in Psychology are important to build strong instruments to evaluate Human Behaviors through different scopes of activity from the Psychological Sciences. However, in order to build a valid and realiable measure, there are several methods and procedures that demand theorical and empirical studies. Therefore, I intend to adquire the following technologies: (1) Structural Equation Modeling, Confirmatory Factorial Analysis and Multidimensional Regression; (2) Empirical Building of instruments through observation of Behaviors and Symptoms; (3) Classical Test Theory (CTT) analysis in different environments; (4) Unidimensional and Multidimensional Item Reponse Theory (IRT) Analysis and Modeling; & (5) Mathematical Modeling of Human Behaviors.  


Ages & Stages Questionnaire Third Edition (ASQ-3) - Cross-cultural adaptation project of a Screening Instrument for Child Development Assessment in the Public Child Care System of the city of Rio de Janeiro, Brazil. Psychometric Properties based on Exploratory Factor Analysis (Cattel's scree plot test, Velicer's MAP Test and Parallel Analysis), Classical Test Theory (Cronbach's Alpha, Item-to-Total Correlation, Domain-to-Overall Correlation, Convergent/Discriminant Correlation Analysis), Item Response Theory (Rasch Measurement Model), and Nonparametric Item Response Theory (Mokken Analysis).

PANAS - Positive Affect and Negative Affect Scale - new studies of Psychometric Properties based on Factor Analysis, Classical Test Theory and Rasch Measurement Model (IRT) in a Brazilian Internet based Sample.

FDI - Filgueiras - Depression Inventory - Studying Psychometric Properties and Factors Structure of a new instrument to assess Depression Symptoms. Item Response Theory (IRT) using Rasch Modeling Analysis will assess items characteristics, and Nonparametric Item Response Theory (Mokken Analysis) will be used to study fidedignitiy and monotonicity. Also, Classical Test Theory (CTT) indexes will be calculated in order to evaluate the psychometric properties of FDI.
