Improvement of Autism Symptoms After Comprehensive Intensive Early Interventions in Community Settings

Area of Science:

• Developmental Psychology
• Behavioral Science
• Clinical Psychology

Background:

• A Naturalistic Developmental Behavioral Intervention (NDBI) program was implemented for preschool children with autism in southern Sweden.
• Evaluating the efficacy of early intensive interventions is crucial for improving outcomes in children with autism spectrum disorder (ASD).

Purpose of the Study:

• To assess the effectiveness of an NDBI program by comparing pre- and postintervention autism symptom severity.
• To determine if NDBI leads to greater improvements in autism symptoms compared to standard community care.

Main Methods:

• A cohort of 67 preschool children with autism participated in the NDBI program.
• Outcomes were measured using the Autism Diagnostic Observation Schedule (ADOS-R) scores.
• Analysis of covariance compared changes in ADOS-R scores between the NDBI group and a control group (n=27) receiving treatment as usual.

Main Results:

• Children in the NDBI group demonstrated a statistically significant reduction in ADOS-R total scores (-0.8 scores/year), indicating symptom improvement.
• The comparison group receiving community treatment showed no significant change in ADOS-R scores (+0.1 scores/year).
• While NDBI participants showed improved ADOS severity scores, the difference between groups was not statistically significant.

Conclusions:

• The findings support previous research suggesting that early intensive interventions, such as NDBI, can improve autism symptoms.
• Despite the need for cautious interpretation of observational data, the results indicate that children with autism benefit from comprehensive early intervention programs.
• This study underscores the importance of evaluating costly intervention programs to ensure they provide tangible benefits for children with autism.
