TitleChild and adolescent well-being index
ParticipantsMaria Teresa G Alves, Amélia Bastos, Maria Eugénia Ferrão (Principal Investigator)
SummaryThis project investigates the measurement of child and adolescent well-being following a deprivation
approach. We consider three dimensions in our index: housing, health and social participation.
Drawing on graded response models (GRM), this study evaluates the psychometric properties of the
self assessment and possession ratings of dataset collected through the application of individual
questionnaires. Microdata is used to check IRT assumptions such as unidimensionality and local item
dependence. The goodness of fit of the GRM to the data and the item characteristic curves are
evaluated. Differential item functioning (DIF) procedures are also performed to detect item bias by
gender and age.
