Abstract
The impact of developmental disorders can be mitigated if early diagnoses are implemented. The Five to Fifteen questionnaire (FTF) could be a suitable tool for early diagnosis of these disorders. We describe the psychometric properties and the characterization of 322 Chilean children of typical development, between 5 and 15 years of age. Levels of consistency and temporal stabilitywere fluctuating between .83 and .93, and between .44 and .86, respectively. From an Exploratory Factorial Analysis emerge 4 dimensions that account for 65.4% of ariance
(KMO = .93; ?2= 3,113.77; gl = 231; p<.01), where a general development dimension is predominating. Differences were found by gender and age. Performance of Chilean and Sweden children indicates similarities at 5 years of age. However from 6 years of age onwards differences were found in almost all domains.We conclude that FTF is avalid and reliable instrument measuring children’s development.
