A Multisite Randomized Controlled Trial Comparing the Effects of Intervention Intensity and Intervention Style on Outcomes for Young Children With Autism

AbstractPivotal response treatment (PRT) is a promising intervention focused on improving social communication skills in children with autism spectrum disorder (ASD). Since robots potentially appeal to children with ASD and may contribute to their motivation for social interaction, this exploratory randomized controlled trial (RCT) was conducted comparing PRT (PRT and robot-assisted PRT) with treatment-as-usual (TAU). Seventy-three children (PRT: n = 25; PRT + robot: n = 25; TAU: n = 23) with ASD, aged 3–8 years were assessed at baseline, after 10 and 20 weeks of intervention, and at 3-month follow-up. There were no significant group differences on parent- and teacher-rated general social-communicative skills and blindly rated global functioning directly after treatment. However, at follow-up largest gains were observed in robot-assisted PRT compared to other groups. These results suggest that robot-assistance may contribute to intervention efficacy for children with ASD when using game scenarios for robot-child interaction during multiple sessions combined with motivational components of PRT.

Urbanized children today have fewer opportunities to interact with nature which may lead to a greater risk of mental health problems. The objective of this randomized controlled trial was to investigate which particular changes in connectedness to nature (CN) would improve psychological well-being (PW) in young children. Six hundred and thirty-nine preschoolers (52.0% boys, age 34.9 ± 9.5 months) participated in Play&Grow, an early environmental education intervention. Children’s CN and PW were evaluated by parents before and after the program with validated measures; the CNI-PPC (four factors) and the SDQ, Strength and Difficulties questionnaire (five factors), respectively. The effectiveness of the intervention on the primary outcomes (CN, PW) as well as the relationship between them was analyzed in a repeated measures path model with intervention status as a causal predictor. Specific CN factors consistently increased ProSocial behavior and reduced Hyperactivity and Emotional problems. In summary, this study showed that the previously reported impact shifted from the total CN score to the specific CN factors. The Play&Grow intervention positively increased children’s CN and improved some aspects of psychological well-being in children which is a preliminary evidence of developmental benefits of connecting young children with nature. Our results indicate promising direction of action for the improvement of families’ psychological health.
