MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The study is a follow-up of a treatment trial on which we have previous reported. In the original Preschool Autism Communication Trial (PACT), 152 children aged 2-4 with autism were randomised to receive the 12 month early intervention or treatment as usual. The type of early intervention used in this study focuses specifically on working with parents. Through watching videos of themselves interacting with their child and receiving feedback from therapists, parents are able to enhance their awareness and response to their child’s unusual patterns of communication; they become better able to understand their child and communicate back appropriately in a focused way. Parents take part in 12 therapy sessions over 6 months, followed by monthly support sessions for the next 6 months. In addition, parents agree to do 20-30 minutes per day of planned communication and play activities with the child.
The study published today is the follow-up analysis of the same children approximately 6 years after the end of treatment. The main findings are that children who had received the PACT intervention aged 2-4 had less severe overall symptoms six years later, compared to children who only received ’treatment as usual’ (TAU) with improved social communication and reduced repetitive behaviours, although no changes were seen in other areas such as language or anxiety. These findings on an international recognised and blind rated observational measure of autism symptoms were accompanied by improvements in children’s communication with their parents for the intervention group, but no differences in the language scores of children. Additionally, parents in the intervention group reported improvements in peer relationships, social communication and repetitive behaviours. However, there was no significant difference between the two groups on measures of child anxiety, challenging behaviours (eg, conduct/oppositional disorder) or depression.
