[Evaluation scale of autistic behavior. Validity and reliability of a scale for autistic behavior detection].
This study aimed to translate, to adapt and to validate the scale of autistic traits (ATA) developed by Ballabriga et al. in Barcelona, by the analysis of 31 patients with mental deficiency and 30 patients with autism, according to the DSM-IV criteria. The "cut off point" found was 15 (p = 0.05); the reliability coefficient was 0.27; the construct validity showed low agreement (kappa = 0.04) and the internal validity was 100%, with all evaluated patients having their clinical diagnosis confirmed through the scale application. The correlation index was 0.42, showing that it is specific for autism. The scale presents discrimination capacity and internal consistency, and the Cronbach's alpha was 0.71. We consider that achieved results show that the scale is reliable to be used in our population.
