“…The intervention was implemented in a one-to-one format in a separate room by a therapist who was assigned to the child. The treatment included elements from various types of interventions for ASD such as sensory integration therapy (Ayres, 1979), TEACCH (Mesibov et al, 2004; Schopler, Reichler, Bashford, et al, 1995), music therapy (Janzen & Thaut, 2018), the Picture Exchange Communication System (Bondy & Frost, 2001), alternative augmentative communication (Iacono et al, 2016; Schlosser & Wendt, 2008), applied behavior analysis (Cooper et al, 2020), speech and language therapy (Vitásková & Kytnarová, 2017), as well as other methods derived from personal clinical experience. Children also participated in other activities common to preschool programs for typically developing children in their daily routine.…”
