The MacArthur-Bates Communicative Development Inventory (CDI) is a parent-focused instrument measuring the communicative development of children aged 8-37 months. CDI allows professionals to screen and develop prognoses for language delays by tapping into parents’ knowledge of their children’s language skills, starting from early comprehension to early vocabulary and grammar expansion.
