Insights
Early Start Denver Model (ESDM) autism intervention is feasible in European community settings. This low-intensity ESDM showed promising results in improving receptive language and reducing autism symptoms in young boys.
Area of Science:
- Developmental Psychology
- Clinical Psychology
- Pediatric Medicine
Background:
- Early autism intervention is crucial for developmental outcomes.
- The Early Start Denver Model (ESDM) is an evidence-based intervention for autism spectrum disorder (ASD).
- Feasibility of implementing ESDM in diverse, non-English speaking community settings requires investigation.
Purpose of the Study:
- To assess the feasibility and effectiveness of a low-intensity Early Start Denver Model (ESDM) intervention for autism in a European community service.
- To evaluate the impact of ESDM on developmental status and core autism symptoms in young children.
Main Methods:
- A cohort of 13 boys (34-54 months) diagnosed with ASD in Austria participated.
- Intervention group (n=7) received 4.6 hours/week ESDM for 12 months; control group (n=6) received usual care.
- Feasibility assessed via parent/teacher questionnaires, fidelity measures, and therapist feedback. Development evaluated using standardized instruments (MSEL, Vineland, CDI, PDDBI).
Main Results:
- ESDM intervention was delivered with high fidelity (>80%) and rated highly acceptable by parents.
- The ESDM group showed a trend toward improved receptive language (p=0.09, ES=0.72).
- Significant reduction in parent-reported core autism symptoms was observed in the ESDM group (PDDBI; p=0.04, ES=0.95).
Conclusions:
- Low-intensity ESDM implementation is feasible in a non-English speaking European community context.
- Findings suggest a potentially favorable response to ESDM compared to usual care, warranting further research.
- This feasibility study provides a foundation for wider adoption of ESDM in similar settings.
Objective:
To investigate the feasibility and effectiveness of early autism intervention with the Early Start Denver Model (ESDM) implemented with low intensity in a community service in Europe.
Methods:
Subjects were boys (n = 13, ages 34-54 months, mean age 43.3 months) consecutively diagnosed with autism spectrum disorder in a regional autism center in Austria. The subjects either received the ESDM intervention for 4.6 hours weekly over 12 months (n = 7) or intervention as usual (n = 6). Feasibility of the ESDM intervention was evaluated by parent and teacher questionnaires, ESDM fidelity measures, and therapists' feedback. Developmental status was assessed through standardized instruments (Mullen Scales of Early Learning [MSEL], Vineland Adaptive Behavior Scales Second Edition, Communicative Development Inventory, Pervasive Developmental Disorder Behavior Inventory [PDDBI], Parenting Sense of Competence Scale) at baseline and after intervention.
Results:
The ESDM intervention was delivered with high fidelity (>80%) by a newly trained multiprofessional team. Acceptability by parents was rated as high. The ESDM was considered to be compatible with both family and preschool routines without any major adaptations. The ESDM group showed a trend toward improved receptive language (MSEL receptive language; p = 0.09, effect size [ES] = 0.72) and reduction in parent-reported core autism symptoms (PDDBI Autism Composite Score; p = 0.04; ES = 0.95). No such improvement was noted in the control group.
Conclusion:
Low-intensity implementation of the ESDM in a non-English-speaking community service context is feasible. Although outcomes from this small feasibility study should be interpreted with caution, our findings suggest a more favorable response to the ESDM intervention group compared with the control group.
