The Portuguese version of the Knowledge of Infant Development Inventory-P (KIDI-P)

Several studies show that parental knowledge about child development and education is relevant to parenting actions. Considering that the lack of assessment instruments specific to this domain in Portugal is an obstacle to cross-cultural research and programme evaluation, the objective of this study was to make available a Portuguese version of the Knowledge of Infant Development Inventory-P (KIDI-P). This inventory (58 items) allows for the calculation of three summary scores (Attempted, Accuracy and Total) that reflect correctness and confidence in one's knowledge. The Portuguese version of the KIDI-P confirmed a unidimensional structure and revealed good internal consistency (α = .89). In a sample of 252 mothers and fathers, educational level showed to be related to KIDI-P scores, unlike parents’ sex and age.
