简要总结
This randomised-controlled trial will assess the effect of an early intervention on the social-communicative abilities and brain activity of infants with elevated likelihood of Autism Spectrum Disorder (ASD). The children´s social-communicative abilities and the related brain activity will be evaluated at three time points: before the start of the intervention (pre-intervention), immediately after its conclusion (post-intervention) and 6 months after its conclusion (follow-up).
详细描述
Previous research has shown that parent-implemented interventions are effective in improving the social skills of children with autism spectrum disorder (ASD).Considering that several differences in social and non-social skills start to emerge before a diagnosis can be made, this project aims to investigate the effects of an adapted prodromal version of an evidence-based parent-mediated intervention (Project ImPACT) in children with an elevated likelihood to develop ASD (namely siblings and children who were born preterm). The effect of the intervention will be evaluated at both behavioural and neural levels. The intervention is suitable for infants and consists of 12 session with the child and his/her parents, of maximum 2 hours each, one session per week, delivered by therapists of the home guidance and home guidance centers in Flanders. Children between 9 and 18 months old and their parents will participate in the study. They will be randomly assigned to the ImPACT intervention group or a no-intervention group (monitoring only). The families will be invited to come to the Faculty of Psychology and Pedagogical Sciences at three time points: before the start of the intervention, immediately after the end of the intervention (which is expected to last 12 weeks) and 24 weeks after the end of the intervention.

结局指标
主要结局
Bigger change from post-test in the intervention group in the parent-child interaction compared to the no-intervention group.
时间窗: Follow-up at 6 months after post-test
Change in quality and frequency of behaviours (with the same unit of measure) within the Parent-Child Interaction coded through the Parent-Infant/Toddler Coding of Interaction (PInTCI). An increase is considered as a positive outcome.
Bigger change from baseline in the parent-child interaction in the intervention group compared to the no-intervention group.
时间窗: Outcome at 3 months after entry(post-test)
Change in quality and frequency of behaviours (with the same unit of measure) within the Parent-Child Interaction coded through the Parent-Infant/Toddler Coding of Interaction (PInTCI). An increase is considered as a positive outcome.
