In this study we investigated the effectiveness of six months of treatment-as-usual (TAU) on communicative-linguistic and adaptive skills of 70 children with autism spectrum disorder from five Italian regions. Specifically, we investigated: (1) the effectiveness of the treatment on communicative-linguistic and adaptive skills, subdividing the children on the basis of their level of development; (2) the outcome predictors of communicative-linguistic skills; (3) the effectiveness of treatments which provide interventions aimed at the development of communicative-linguistic skills versus treatments that do not provide similar interventions. The results showed (1) a communicative-linguistic and adaptive enhancement in children with higher levels of development; (2) level of development, adaptive functioning and severity of autistic symptoms are significant predictors of outcome of linguistic-communicative skills. Finally we found that (3) after 6 months, TAU which includes treatments aimed at the development of communicative-linguistic skills has an increased effectiveness on adaptive communication skills (measured by the Vineland II communication scale) in children with higher developmental levels.
