Berard AIT is a 10 hour auditory intervention. There are 20 supervised listening sessions of 30 minutes each, completed over 10 or 12 consecutive days. AIT has many scientific studies. The minimum age recommended is 3 years.

AIT Practitioners are trained professionals. AIT Session prices in the USA range from about $1,200 to 2,000. Prices will vary internationally by county.

Report on the Changes in Scores for a Group of 13 Children with Autism After Berard Auditory Integration Training (AIT)

by Rosalie Seymour, Speech Therapist and Audiologist, AIT Practitioner and Maoilíosa Ó Rathaille, B.A., M.Sc., C.Stat., Lecturer in Mathematics and Statistics, Waterford Institute of Technology

"AIT does, in fact, appear to be a worthwhile, frequently beneficial intervention which confers improvement in a number of symptoms, in a significant proportion of disorders on the autism spectrum."

This study was done to answer two questions:

To determine whether AIT made any difference for those children with autism who participated .
The next question to answer was, is this difference bigger than one can expect from ordinary chance?

Two methods of assessment were chosen: the Autism Treatment Evaluation Checklist (ATEC) of Drs Rimland and Edelson, and the Autism Behaviour Checklist (ABC) of Anand and Singh.

While 17 children with the diagnosis of Autism were included in this study, in total there were 13 parents who completed their before- and- after ATEC checklists and 12 who returned their ABC forms. These checklists were completed before AIT started, and then four months after the conclusion of AIT.

The ATEC gives a Total score, as well as sub scores for

Speech,
Sociability
Cognitive / Sensory awareness, and
Health-Physical-Behavioural issues.

The ABC has a Total score, then also

Hyperactivity
Irritibility
Lethargy
Stereotypy and
Inappropriate Speech… (One point must be clarified, on this checklist a mute child will have a lower – i.e. better - score than a child who speaks a lot but it is inappropriate in content or style.)

As we get to know more about the results we get from AIT, we might be able to learn what to offer people as expected outcomes. This does not seem altogether simple, since there is quite a spread of possibilities of changes after AIT, making prediction a bit hard to do.

RESULTS Pre-AIT and Post-AIT scores were calculated for each of the sub-scores and for the totals for both ATEC(n=13) and ABC(n=12) scores. The hypothesis was tested to see if there was any change in performance between the original scores and the scores found after the treatment was carried out (post-treatment – pre-treatment). The results are summarised in Tables 1(ATEC) and 2(ABC) below. In all cases, the 1-sample sign test for a median is used.

Table 1: Comparison of ATEC score changes for the two groups after the study period

Factor	Median of the differences	P-value: test of no difference	Significant (5%)
Speech	0	0.508	No
Sociability	-3	0.0005	Yes
Sensory/ Cognitive awareness	-1	0.0117	Yes
Health/ physical/ behaviour	-5	0.2668	No
Total	-9	0.0005	Yes

These calculations show that there were improvements for the group of children in Sociability, Sensory/Cognitive awareness, and the total score.

The changes in Sociability, Sensory – Cognitive and the Total scores are significant. That is, we can confidently say they were not as a result of chance but likely to have been due to AIT.

Table 2: Comparison of ABC scores

Factor	Median of the differences	P-value: test of no difference	Significant (5%)
Irritabilty	-11	0.002	Yes
Lethargy	-6	0.0386	Yes
Stereotypy	-4.5	0.508	No
Hyperactivity	-16	0.0063	Yes
Inappropriate speech	-4	0.289	No
Total	-10	0.0063	Yes

These results show that there were improvements for the group in all the areas covered by this checklist. There were significant changes in the areas of Irritibility, lethargy, Hyperactivity, and the Total scores. That is, we can confidently say they were not as a result of chance but are likely to have been due to AIT.

CONCLUSION

The results of this study confirm the results of other studies : (Autism Research Institute) that have shown significant changes occur in areas of importance to the well-being and progress of children with autism.

To quote Dr Steven Edelson (Autism Research Institute):

‘…a review of the available literature on AIT has produced 23 studies with positive results and only 3 claiming no benefits from AIT. While none of the research done thus far on AIT is of Nobel Prize quality, the positive studies are far more credible than those with negative results. As we point out in our comments, the 3 studies that claim no benefits are deeply flawed, with conclusions that are not supported by the research procedures nor the research data.

'AIT does, in fact, appear to be a worthwhile, frequently beneficial intervention which confers improvement in a number of symptoms, in a significant proportion of disorders on the autism spectrum.’
