Screening of Developmental Difficulties during the Transition to Primary School.

The five-to-fifteen (FTF) questionnaire is a screening tool completed by parents that is able to distinguish developmental disorders in children aged 5 to 15 years old. The current study aimed to characterize the developmental difficulties by gender and school age (kindergarten and first grade) of children in their transition to primary school, using the Spanish-language version of the FTF questionnaire. The participants were 541 parents of typically developed children from kindergarten and first grade in public schools in Chile.
