The capacity of the Child Behavior Checklist 1½-5 (CBCL 1½-5) to identify children with autism spectrum disorder (ASD) at 18 months was tested on 37 children clinically referred for ASD and 46 children at elevated likelihood of developing ASD due to having an affected brother/sister. At 30 months the clinically referred children all received a confirmatory diagnosis, and 10 out of 46 siblings received a diagnosis of ASD. CBCL 1½-5 profiles were compared with a group of matched children with typical development (effect of cognitive level controlled for). The capacity of the CBCL 1½-5 DSM Oriented-Pervasive Developmental Problems scale to differentiate correctly between children diagnosed with ASD and children with typical development appeared dependent on group ascertainment methodology., Author(s): Natasha Chericoni [sup.1] , Giulia Balboni [sup.2] , Valeria Costanzo [sup.1] , Alice Mancini [sup.1] , Margherita Prosperi [sup.1] , Roberta Lasala [sup.1] , Raffaella Tancredi [sup.1] , Maria [...]

This study investigated the prevalence and type of gastrointestinal (GI) and food selectivity (FS) symptoms in 163 preschoolers with ASD, and their possible links with core ASD features and emotional/behavioural problems. 40.5% of children with ASD had at least one severe GI symptom or FS. Preschoolers with and without GI symptoms and with and without FS were significantly different on several emotional/behavioural problems and restrictive/repetitive behaviours, whereas they did not differ significantly on performance IQ and autistic severity. The GI plus FS group presented with Sleep Problems, Self-injurious Behaviors and Anxiety Problems. Results indicated the need for early identification of GI disturbances and FS in order to design tailored intervention for these symptoms frequently associated to challenging behaviours in ASD., Author(s): Margherita Prosperi [sup.1] , Elisa Santocchi [sup.1] , Giulia Balboni [sup.2] , Antonio Narzisi [sup.1] , Margherita Bozza [sup.3] , Francesca Fulceri [sup.1] , Fabio Apicella [sup.1] , Roberta [...]
