That commitment to evidence based interventions is of critical importance for New Brunswick's autistic children and youth and has been largely honored since then by the Province of New Brunswick. There is, however, despite the existence of a high quality autism intervention training program at UNB, persistent pressure from some pockets, particularly in the Saint John and St. Andrews areas, to employ non-evidence based interventions with autistic pre-schoolers and students. In Saint John in particular, the "anything but ABA" sentiments of some influential people in the autism "community" have resulted in negative and inaccurate perceptions of ABA amongst some parents busy with the demands of child raising, dealing with their children's autism and, like all of us, struggling to get by. At the same time the "anything but ABA" group tends to promote any intervention with a nice sounding name that looks fun on its face, anything as long as it is not ABA.
The intervention which is currently in vogue amongst New Brunswick's "anything but ABA" lobby is RDI. RDI sounds so nice - Relationship Development Intervention. After all how can one possibly be against "Relationship Development"? And it is an "Intervention"! It sounds so professional it must be evidence based right? Well no, not really.
One of the leading reviews of the evidence basis of the effectiveness of autism interventions is the MADSEC Autism Task Force Report which reviewed the professional literature in 1999-2000 and concluded at pages 60-61:
Based upon a thorough examination of numerous methodologies considered as interventions
for children with autism, the MADSEC Autism Task Force has characterized the interventions
reviewed as follows:
• Substantiated as effective, based upon the scope and quality of research:
Applied behavior analysis. In addition, applied behavior analysis’ evaluative procedures are effective not only with behaviorally-based interventions, but also for the systematic
evaluation of the efficacy of any intervention intended to affect individual learning and
behavior. ABA’s emphasis on functional assessment and positive behavioral support will
help meet heightened standards of IDEA ‘97. Its emphasis on measurable goals and reliable
data collection will substantiate the child’s progress in the event of due process.
• Shows promise, but is not yet objectively substantiated as effective for individuals with autism using controlled studies and subject to the rigors of good science:
Auditory Integration Training, The Miller Method, Sensory Integration, and TEACCH.
• Repeatedly subjected to the rigors of science, which leads numerous researchers to conclude the intervention is not effective, may be harmful, or may lead to unintended consequences:
Facilitated Communication.
• Not scientifically evaluated:
Greenspan’s DIR/”Floor Time,” Son-Rise.
There is no mention of RDI in the 1999-2000 MADSEC review but RDI has emerged more prominently since then in autism workshops offered in New Brunswick and elsewhere and there has been another important and more recent review of the scientific studies of the effectiveness of autism interventions - the American Academy of Pediatrics report Management of Children With Autism Spectrum Disorders published online October 29, 2007. The AAP concluded, at page 1165m with respect to the evidence basis of RDI that:
If a reader wants to understand how weak the evidence in support of RDI effectiveness is, as summarized by the AAP above, they can compare it to the AAP summary, at page 1164, of the evidence in support of effectiveness of ABA:
The effectiveness of ABA-based intervention in ASDs has been well documented through 5 decades of research by using single-subject methodology21,25,27,28 and in controlled studies of comprehensive early intensive behavioral intervention programs in university and community settings.29–40 Children who receive early intensive behavioral treatment have been shown to make substantial, sustained gains in IQ, language, academic performance, and adaptive behavior as well as some measures of social behavior, and their outcomes have
been significantly better than those of children in control groups.31–40
When the New Brunswick government committed to evidence based approaches to treating and educating autistic children it adopted a very sound policy which has helped many autistic children. Even in Saint John where the "anything but ABA" sentiment has been strongest, autistic children receive evidence based intervention at the Stepping Stones autism agency. But why is it important to provide evidence based interventions?
In Children with autism deserve evidence-based intervention, The evidence for behavioural therapy, MJA 2003; 178 (9): 424-425, Jennifer J Couper and Amanda J Sampson, reviewed some of the evidence in support of the efficacy of behavioral interventions for autism. The authors stressed the importance of an evidence based approach to autism interventions:
While ineffective therapies may be harmless, they waste parents' money and the child's valuable therapy time. Furthermore, the delay in implementing effective treatment may compromise the child's outcome.
The choice of autism interventions offered by New Brunswick autism agencies should be determined by the evidence basis in support of their effectiveness. Failure to provide evidence based effective autism interventions may compromise the outcome for children with autism disorders in New Brunswick.
Autistic children deserve evidence based intervention.
At this time RDI does not meet that standard.

RDI focuses on activities that elicit interactive behaviors with the goal of engaging the child in a social relationship so that he or she discovers the value of positive interpersonal activity and becomes more motivated to learn the skills necessary to sustain these relationships.56 Some reviewers have praised the face validity of this model, which targets the core impairment
in social reciprocity. However, the evidence of efficacy of RDI is anecdotal; published empirical scientific research is lacking at this time.
