VICENTE, BENJAMÍN; NAVAS, LEANDRO; BELMAR, MARTA  and  HOLGADO, F. PABLO. Analysis of a scale for the assessment of attention deficit disorder with hyperactivity in Chilean children. Rev. méd. Chile [online]. 2010, vol.138, n.12, pp.1502-1509. ISSN 0034-9887.

Background: Epidemiologic studies may be used as a starting point to improve interventions and improve diagnosis, with instruments that are both reliable and adequate. Aim: To analyze the psychometric properties of the Attention Defcit Disorder Evaluation Scale (ADDES) in Chilean primary and high school students. Material and Methods: The ADDES was applied by 142 teachers to 254 students. Attention Defcit Disorder was already diagnosed in 144 students. Explanatory and confirmatory factorial analyses were carried out. Results: Confirmatory Factorial Analysis (CFA) proved that the model suggested by the authors could not be replicated in the Chilean sample. Exploratory Factorial Analysis (EFA) showed that three new factors came out of the analysis. CFA was applied to the new model and modification indexes suggested the introduction of new saturations. Based on the model with the best goodness-of-fit, psychometric characteristics were evaluated. Conclusions: The ADDES adapted to the Chilean context has a high reliability and a strong discrimination ability, allowing the evaluation of behavior disorders, hyperactivity/impulsivity and attention deficit.

Keywords : Attention deficit disorders with hyperactivity; Child; Mental disorders diagnosed in childhood.
