“…According to the Diagnostic and Statistical Manual of mental disorders5th edition (DSM-5) criteria, people with ASD fall on a continuum with individuals characterized by the severity of their symptoms in the two core domains. Furthermore, intellectual disability and/ or language impairment contribute to the heterogeneous presentation of ASD.Behavioral problems, such as tantrums, comorbidity with other psychiatric disorders, abnormal sleep patterns and unusual feeding behaviors, are often present in children with ASD and the everyday management of these problems is a challenge for clinicians and families (Dominick, Davis, Lainhart, Tager-Flusberg, & Folstein, 2007). Although not a diagnostic feature of ASD, feeding problems are common in this clinical population, and food selectivity is the most frequent one (Ahearn, Castine, Nault, & Green, 2001;Cornish, 1998;Dominick et al, 2007;Heiss, Moody, Crosley, & Campbell, 2005;Kerwin, Eicher, & Gelsinger, 2005;Nadon, Feldman, Dunn, & Gisel, 2011;Schmitt, Heiss, & Campbell, 2008;Schreck, Williams, & Smith, 2004;Williams, Gibbons, & Schreck, 2005;Williams, Dalrymple, & Neal, 2000).…”
