The Brignell et al. systematic review aimed to assess the treatment effects for ASD in minimally verbal children. Of 8248 studies, only two (Focused playtime intervention-FPI and Picture Exchange communication System-PECS; N=154, aged 32 months to 11 years) met the authors' inclusion criteria. The FPI study found no significant effect for the intervention group on spoken communication. However, the children with lower expressive language ability at baseline benefited more from the intervention than those with better expressive language at baseline. The PECS study found significant effect in the frequency of PECS use and verbal and non‐verbal initiations, but not in expressive vocabulary or social communication immediately after postintervention. Neither intervention study resulted in a sustained improvement in spoken or non-verbal communication in most children. Also, neither study investigated adverse events, other communication skills, quality of life, or behavioral outcomes.
