A Comparison Controlled Study Examining Outcome for Children With Autism Receiving Intensive Behavioral Intervention (IBI).

This study compared two different early intervention programs for young children with autism. Twenty-five children received intensive behavioral intervention (a structured therapy approach), while 14 children received a mix of different autism therapies. After 14 months, children in the intensive behavioral program showed bigger improvements in thinking skills, daily living skills, and autism symptoms. However, the study has some design limitations that make it harder to draw strong conclusions.

This comparison-controlled study examined outcomes for 25 preschool children with autism receiving center-based Intensive Behavioral Intervention (IBI) versus 14 children receiving autism-specific eclectic special education over 14 months. Both treatments were considered appropriate by diagnosing professionals, with parents choosing the intervention. Children in the IBI group showed significantly greater improvements in intellectual functioning, adaptive behavior, and autism severity compared to the comparison group. The authors suggest IBI effects may be similar to Early Intensive Behavioral Intervention (EIBI) but emphasize caution in interpretation due to the study's comparison-controlled design limitations.

Results suggest potential benefits of center-based IBI for preschool children with autism in cognitive, adaptive, and autism-specific domains. However, the non-randomized design and small sample limit confidence in conclusions. Further randomized controlled trials are needed to establish stronger evidence for IBI effectiveness compared to other intervention approaches.

The study uses a comparison-controlled design rather than randomized controlled trial methodology. Small sample sizes (25 vs 14 participants) limit generalizability. Parent choice of intervention may introduce selection bias. The authors explicitly note limitations inherent in their study design that require cautious interpretation.

This study evaluated the effects of a center-based Intensive Behavioral Intervention (IBI) model for preschool aged children with autism. Outcomes of 25 children receiving IBI was compared to the outcomes of 14 children receiving autism specific, eclectic, special education. Both provisions were described as appropriate treatment options by the professional agency who diagnosed the children, and the decision of where to enroll the child was made by the parents after consultations with the specialists. After 14 months of treatment, children from the IBI group improved significantly on standard scores in intellectual functioning and adaptive behavior and had a significant reduction in autism severity compared to the children in the autism specific, eclectic, special education group.

Results suggest that preschool aged children with autism may make large gains in intellectual and adaptive functioning and improvement in autism severity with IBI, and that effects of IBI may be similar to that of EIBI. These findings must be interpreted with caution due to the limitations inherent in the present comparison-controlled design.
