Early Intensive Behavioral Intervention (EIBI) is a comprehensive treatment approach for children with autism spectrum disorder (ASD). Based on applied behavior analysis (ABA) principles, EIBI aims to teach new skills and reduce problem behaviors through structured, intensive, and individualized interventions. The treatment typically involves one-on-one sessions with a trained therapist and often includes parent training to facilitate skill generalization in the home environment.
EIBI has garnered significant attention due to its potential to improve outcomes for children with ASD. Research indicates that early intervention can lead to better long-term results, including enhanced language and social skills, and decreased problem behaviors. The Lovaas (1987) study is considered a seminal work in the field of EIBI and has significantly influenced the approach to early intervention for children with ASD.

Overview of the Lovaas (1987) Study
Methodology
The study compared the outcomes of two groups of children with ASD who received different types of intervention. One group received intensive behavioral intervention based on the principles of Applied Behavior Analysis (ABA), while the other group received less intensive, eclectic interventions. The study followed the children over several years and assessed their progress in various areas, including language, adaptive behavior, and cognitive functioning.
Groundbreaking Results
The results of the study were groundbreaking, as they showed that children who received intensive behavioral intervention made significant gains in their development compared to those who received less intensive interventions. The study found that nearly half of the children who received intensive behavioral intervention achieved normal intellectual and educational functioning by the age of 7, while none of the children in the comparison group achieved this level of functioning.
Impact on the Field of Autism Research
These findings provided strong evidence for the effectiveness of EIBI in improving outcomes for children with ASD and have had a profound impact on the field of early intervention for autism.
Methodology and Participants
The Lovaas (1987) study utilized a randomized controlled trial design, which is considered the gold standard for evaluating the effectiveness of interventions. The study included 19 children with ASD who were randomly assigned to either the intensive behavioral intervention group or the comparison group. The children in the intensive behavioral intervention group received 40 hours per week of one-on-one therapy with a trained therapist, while the children in the comparison group received less intensive, eclectic interventions that did not follow a specific treatment protocol.
The study followed the children over several years and assessed their progress using standardized measures of language, adaptive behavior, and cognitive functioning. The researchers also collected data on the children’s social skills, problem behaviors, and overall functioning. The study utilized rigorous methodology to ensure the validity and reliability of the findings, including blinded assessments and statistical analyses to compare the outcomes of the two groups.
Key Findings and Results
The key findings of the Lovaas (1987) study were highly significant and have had a lasting impact on the field of early intervention for autism. The study found that children who received intensive behavioral intervention made substantial gains in their development compared to those who received less intensive interventions. Specifically, nearly half of the children in the intensive behavioral intervention group achieved normal intellectual and educational functioning by the age of 7, while none of the children in the comparison group achieved this level of functioning.
In addition to improvements in cognitive functioning, language, and adaptive behavior, the study also found that children in the intensive behavioral intervention group showed significant reductions in problem behaviors and improved social skills. These findings provided strong evidence for the effectiveness of EIBI in improving outcomes for children with ASD and have had a profound impact on the way early intervention is approached and implemented for this population.
Implications for Early Intervention and Autism Treatment
The findings of the Lovaas (1987) study have had far-reaching implications for early intervention and autism treatment. The study provided strong evidence for the effectiveness of EIBI in improving outcomes for children with ASD, particularly when implemented at an early age. As a result, EIBI has become widely recognized as a best practice approach for early intervention for children with ASD, and it has been recommended by leading professional organizations, such as the American Academy of Pediatrics and the National Institute of Mental Health.
The study also highlighted the importance of early intervention in improving long-term outcomes for children with ASD. Research has shown that early intervention can lead to better long-term outcomes for children with ASD, including improved language and social skills, as well as reduced problem behaviors. As a result, there has been a growing emphasis on early identification and intervention for children with ASD, with efforts to increase access to early intervention services and support for families.
Criticisms and Limitations of the Study
Methodological Concerns
The Lovaas study, published in 1987, has had a significant impact on the field of early intervention for autism. However, it is not without its criticisms and limitations. One major criticism is the study’s small sample size, which consisted of only 19 children with Autism Spectrum Disorder (ASD). Although the study employed rigorous methodology to ensure the validity and reliability of the findings, a larger sample size would have increased the generalizability of the results.
Limitations of Intensive Behavioral Intervention
Another limitation of the study is its focus on a specific type of intensive behavioral intervention based on the principles of Applied Behavior Analysis (ABA). While ABA has been shown to be effective for many children with ASD, it may not be suitable or accessible for all families. This raises concerns about the feasibility and acceptability of ABA for some families.
The Need for Diverse Early Intervention Approaches
As a result, there is a need for research on other types of early intervention approaches that may be more feasible or acceptable for some families. This highlights the importance of exploring alternative interventions that can cater to the diverse needs and circumstances of families affected by autism.
Future Directions and Research in Early Intensive Behavioral Intervention
Despite its limitations, the Lovaas (1987) study has paved the way for future research and advancements in early intensive behavioral intervention for autism. There is a growing emphasis on developing and evaluating new approaches to early intervention that may be more feasible or acceptable for families, particularly those from diverse cultural and linguistic backgrounds. Research is also focused on identifying individualized treatment approaches that take into account each child’s unique strengths and needs.
In addition to developing new approaches to early intervention, there is also a need for research on how to effectively disseminate and implement evidence-based practices in community settings. Many families face barriers to accessing early intervention services, such as long waitlists or lack of insurance coverage. As a result, there is a need for research on how to increase access to early intervention services and support for families, particularly those from underserved communities.
In conclusion, the Lovaas (1987) study has had a profound impact on the field of early intervention for autism, providing strong evidence for the effectiveness of EIBI in improving outcomes for children with ASD. While the study has limitations, it has paved the way for future research and advancements in early intensive behavioral intervention, with a growing emphasis on developing new approaches that are feasible and acceptable for families from diverse backgrounds. As research continues to advance, there is hope that more children with ASD will have access to high-quality early intervention services that can significantly improve their long-term outcomes.
