Our Research

UKYAP has undertaken a number of research studies, including examining outcome for children we work with:

UK YAP Outcome Research

Hayward, D., Eikeseth, S., Gale, C., & Morgan, S. (2009). Assessing progress during treatment for young children with autism receiving intensive behavioural interventions. Autism, 13 (6), 613 – 633

As part of the UCLA Multi-Site Young Autism Project, UK YAP examined progress of 44 children after one year of treatment in the UK. Results showed children improved significantly on: IQ; Visual-spatial IQ; Language Comprehension; Expressive Language; Social Skills; Motor Skills; and Adaptive Behaviour. Eighty-nine percent of the children made gains in IQ with a mean increase of 16 points after one year of treatment. These findings are consistent with previous studies demonstrating the benefits of EIBI treatment for children with autism and related developmental disorders.

This study reports outcome in adolescence for some of the children who received EIBI with UKYAP. Nineteen children, who received two years of EIBI starting at a mean age of 2-years-and-11-months were assessed 10 years after EIBI ended. Results showed the participants significantly increased their cognitive and adaptive standard scores during the two years of EIBI, and that these gains were maintained at follow-up, 10 years after the EIBI had ended. Participants also showed a significant reduction in autism symptoms between intake and follow-up. At follow-up, none of the participants had received any additional psychiatric diagnoses, and none were taking any psychotropic medication. Results indicate that treatment gains achieved in EIBI are maintained into adolescence.
