Abstract

La psicometria è quella branca della psicologia che si occupa di tradurre in termini numerici le caratteristiche psicologiche della persona o dei suoi comportamenti. Questo approccio ha portato a sviluppare strumenti di misura con l'obiettivo di rendere condivisibili le entità di caratteristiche che altrimenti sarebbero valutabili in un'ottica esclusivamente soggettiva e descrittiva (Stevens, 1951). Per perseguire tale obiettivo occorre considerare che la misura di caratteristiche psicologiche è prevalentemente indiretta ovvero ottenuta mediante inferenza probabilistica piuttosto che attraverso assunzione diretta del dato. Da qui nasce l'esigenza di utilizzare particolari modelli che, nella stessa logica della taratura statistica degli strumenti di misura, si basano sulla inversione di misure indirette.
