Symposium #258
CE Offered: BACB
Early Intensive Behavioral Intervention: Intensity and Quality Is Strongly Related to Improvements in a Broad Range of Outcome Measures
Sunday, May 28, 2023
6:00 PM–6:50 PM
Convention Center Mile High Ballroom 3C
Area: AUT/CSS; Domain: Service Delivery
Chair: Sigmund Eldevik (Oslo Metropolitan University)
Discussant: Jane S. Howard (Therapeutic Pathways/Trumpet Behavioral Health)
CE Instructor: Sigmund Eldevik, Ph.D.

We will present data following two years of Behavioral Intervention from two sites in Norway and following 6-12 months of Behavioral Intervention from a newly started center in the UK. A broad range of outcome data will be presented and related to the recently published frameworks for evaluating the effects of intervention for children with autism. We will also explore if a dose-response relationship between intervention hours and outcome can be found on a broader set of outcome measures and discuss pros and cons of different models of service delivery.

Instruction Level: Basic
Keyword(s): Behavioral Intervention
Target Audience:

Anyone implementing EIBI

Learning Objectives: describe broader measures of outcome describe expected outcome of EIBI explain the importance of quality and intensity of intercention

Early Intensive Behavioral Intervention (EIBI) Provided in Local Mainstream Preschools in Norway; Higher Intensity and Quality Gives Better Outcome

SIGMUND ELDEVIK (Oslo Metropolitan University), Roy Tonnesen (Fagteam Autsime, Pedagogisk Psykologisk Tjeneste), Kristine Berg Titlestad (Høyskolen Vestlandet), Hege Aarlie (Høyskolen Vestlandet), Silje Nikolaisen (Centre for Early Intervention, Oslo), Christine Lie (Centre for Early Intervention, Oslo)

We will present outcome data following two years of EIBI from two EIBI sites in Norway, Oslo and Bergen. The participants were placed in a higher intensity group (n=22), a lower intensity group (n=33) and a treatment as usual group (n=10). We will report outcome on a wide variety of measures; autism severity measured with the Childhood Autism Rating Scale, adaptive behavior measured with the Vineland Adaptive Behavior Scales, aberrant behaviors measured by the Aberrant Behavior Checklist and preferences measured with the Socially Mediated and Automatic Reinforcers Questionnaire. Effects will be discussed in terms of a dose-response relationship, validity, and recently proposed frameworks for measuring outcome of EIBI.


Preliminary Outcomes of Early Intensive Behavioral Intervention (EIBI) Provided in a Centre-Based Model in London, United Kingdom (UK); Adopting A Broader Framework for Evaluating Outcome

SIGMUND ELDEVIK (Oslo Metropolitan University), Sasha Zerkalova (First Bridge Centre, London, UK), Mikaela Green (First Bridge Centre, London, UK)

The centre-based model of service delivery developed over the last 2 years at the First Bridge Centre in London will be presented. Possible pros and cons of centre-based provision compared to other models of service delivery will be discussed. A wide range of outcome data from the centre will be presented. Outcome after 6 months on skill acquisition, autism severity and an increased preferences for social stimuli will the presented for 12 children enrolled at the centre. Outcome at 12 months on adaptive behaviors, autism severity and problems behaviors will be presented for 8 children and compared to the published outcome of other EIBI provision models and suggested benchmarks.
