CDI
Child Development Inventory - Language Profile (CDI)
In its language form, the CDI is a parent questionnaire for screening oral language development in children aged 15 months to 5 years 11 months. It assesses two core dimensions, expressive language and language comprehension, using items ordered according to developmental progression. The tool makes it possible to estimate a language development age, to detect a possible delay early, and to guide the clinical decision toward further assessment when the profile appears below the expected age. It is particularly useful in developmental psychology, pediatrics, early childhood consultations, and language disorder screening contexts, because it is quick, simple to administer, and based on parents' everyday observations.

Scoring & interpretation
Each item is scored Yes or No. Yes answers are added up separately for the two domains, LEX for expressive language and LCO for language comprehension. The raw scores are then plotted on the scoring grid to obtain a developmental age for each domain. Interpretation is based on comparing these developmental ages with the child's chronological age, identifying the risk zones of the profile. A high-risk line corresponds to 85% of chronological age and a very high-risk line to 70%. A significant gap or a highly uneven profile should lead to a thorough clinical evaluation.
