Study Notes
Early Autism Interventions and Child Development
- Study Focus: Examining the link between intervention intensity and developmental outcomes in young autistic children.
- Data Source: 144 studies (9,038 children) from a prior meta-analysis (November 2021 search).
- Study Design: Systematic review and meta-analysis. Included quasi-experimental and randomized controlled trials of non-pharmacological interventions for autistic children under 8 years old.
- Intervention Metrics: Examined intervention amount using daily intensity, duration, and cumulative intensity.
- Outcome Measures: Developmental gains across any domain, measured using Hedges' g effect sizes.
- Key Findings: No significant association was found between intervention amount and intervention effects. Intensifying commonly used interventions did not show improved outcomes.
- Conclusion and Implications: Evidence does not support the idea that increased intervention intensity leads to better outcomes for autistic children. Recommendations for intervention should consider developmental appropriateness, rather than focusing solely on intensive intervention protocols.
- Participants: The average age of participants was 49.3 months with a standard deviation of 17.2 months. The average percentage of males in the studies was 82.6% with a standard deviation of 12.7%.
- Methodology: Multiple coders independently extracted data. Meta-regression models accounted for several factors including outcome domain, age of participants, study design, and bias risk. Analysis period was from June 2023 to February 2024. Study adhered to PRISMA guidelines.

Description
This quiz explores the findings of a systematic review examining the effectiveness of varying intensities of non-pharmacological interventions for autistic children. Based on data from 144 studies, it discusses the lack of significant association between intervention intensity and developmental outcomes. Test your understanding of the implications of these findings for early childhood development.
