Evidence Based Practice for Relationship Development Intervention (RDI™)

development intervention program. Autism, 11(5), 397-411.

 Gutstein, Burgess, & Montfort (2007) report on the 3-year follow-up of 16 children who met 'gold standard' criteria (ADOS/ADIR) for autism, Asperger’s syndrome or autism spectrum disorder prior to treatment with RDI.  Marked clinical improvements after RDI were reported; for example, whereas prior to treatment 10 had ADOS scores corresponding with the diagnosis of autism, none did so at follow-up, at which point five were classified as ‘autism spectrum’ and five as ‘non-autism’. There were especially marked improvements in the children’s capacity to share experiences with others.  Semi-structured interviews with parents revealed that the children’s flexibility had significantly improved. Moreover, there had been positive changes in the children’s educational placements.  In this study there was not a treatment-as-usual control group (a previous pilot study had included such a control group who did not show the gains of the RDI-treated group). Having said this, the magnitude and breadth of this response to RDI renders it very unlikely that the effects were non-specific.

Psychology & Psychiatry, 45(8), 1420-1430.

 Aldred, Green, & Adams (2004) report a randomized control trial of an intervention for autism that has close affinity with RDI in its attempt to foster developmentally effective parental input through a focus upon the children’s social deficits. The approach ‘educated parents and trained them in adapted communication tailored to their child’s individual competencies’.  
 
The study reported significantly greater improvements in the treated vs. untreated group of children with autism, on a range of outcome measures:  total scores on the Autism Diagnostic Observation Schedule, expressive language, parent-child interaction, and the children’s initiation of communication.  The authors concluded:
 
'this study suggests that a specific intervention that addresses bi-directional adult/child communication breakdown, joint attention, and is tailored to the specific needs of the cases can improve autistic symptoms across severity and age groups in terms of quality reciprocal communication and expressive language'.

Like RDI, this treatment approach provided specialized structured interventions that scaffold social interaction.  The uniqueness of RDI lies in its sharper focus on links between social relatedness and the capacity to engage in flexible thinking and coping through the guided-participation relationship.

 In a series of recent (and ongoing) studies, J. A. Hobson and colleagues (Hobson et al., 2008; Hobson & Hobson, 2008; Hobson, 2009; Hobson et al., 2009; Hobson & Gutstein, 2010), have followed children/adolescents with autism and their families (participating in RDI programs) over time. On the basis of prospective study and retrospective chart review, preliminary results of the above studies (note: research is ongoing) suggest that this approach may yield significant changes in global clinical/psycho-social functioning as well as in improving qualities of parent-child interaction and social communication.
