Summary
Parent-managed autism interventions showed improvements in adaptive behavior but not IQ. Children over 72 months did not reach typical functioning, indicating a need for further research into these models.
Area of Science:
- Developmental Psychology
- Clinical Psychology
- Pediatric Medicine
Background:
- Parent-managed behavioral interventions for autism are under-researched.
- Limited data exists on the long-term effectiveness of these models.
Purpose of the Study:
- To analyze the effectiveness of parent-managed behavioral interventions for young children with autism.
- To assess changes in IQ, adaptive behavior, and language development.
Main Methods:
- Analysis of data from 66 children with autism receiving parent-managed interventions.
- Tracking progress over a mean of 31.6 months and a 12-month period for a subset of children.
Main Results:
- No significant change in IQ scores observed (N=22).
- Significant increase in Vineland adaptive behavior scores by 8.9 points (N=21).
- Progress over 12 months included gains in mental age (5.4 months), adaptive behavior (9.7 months), and language (5.1 months).
Conclusions:
- Parent-managed interventions improved adaptive behavior but not IQ in young children with autism.
- Interventions did not replicate outcomes from clinic-based programs.
- Effectiveness and professional service adequacy in parent-managed models require further investigation.
