Standardization of the Gender Assignment and Agreement Assessment in the Greek Language: Preliminary Evidence from Bilingual Greek-Albanian School Age Children

(1) Background: Given the scarcity of data on the psychometric evaluation of measures used with typically developing Greek-speaking bilinguals, this study aims to present preliminary evidence for the standardization and the psychometric evaluation of a gender assignment and agreement assessment designed for the Greek language (henceforth, GAAGL Assessment) employing real and pseudo-words. This is the first study to standardize the GAAGL Assessment and to explore its discriminatory ability with typical populations. (2) Methods: The assessment was designed as part of the BALED project which targeted language skills in bilingual children for whom one language is Greek. For the psychometric evaluation and the exploration of the test's discriminatory ability we ran a Cronbach's alpha analysis and a Youden Receiver Operating Characteristics (ROC) analysis across the domains and sub scores of the test. Our sample consisted of 53 typically developing Greek monolingual children and 57 age-matched Greek-Albanian-speaking bilinguals. (3) Results: The results showed: (a) a high internal consistency for the GAAGL Assessment across its four main tasks and (b) excellent discriminatory ability, since statistically significant positive discrimination was detected between monolingual and bilingual children in the tasks and scores of the GAAGL Assessment.
