The association between the social and communication elements of autism, and repetitive/restrictive behaviours and activities: a review of the literature.
Autism traits may group into two clusters, not three—so merge social-communication goals and treat repetitive behaviors on their own track.
01Research in Context
What this study did
Renate and her team read every paper they could find on autism traits. They looked at how social problems, language delays, and repetitive actions link together. The goal was to see if the famous “triad of impairments” still holds up.
What they found
The three-part picture in the DSM does not match the data. Studies show social and communication issues blend into one block. Repetitive behaviors often stand alone, not tied to the other two. In short, autism may have two main factors, not three.
How this fits with other research
Baranek et al. (2005) also reviewed repetitive behaviors, but they zoomed in on brain chemistry. Their call for team work with behavior analysts pairs well with Renate’s plea to rethink how we slice symptoms.
Izawa et al. (2012) showed autistic kids learn motor skills slower and lean hard on body feedback. That single-track style fits Renate’s idea that repetitive-sensory traits form their own cluster, separate from social-communication issues.
Mantzalas et al. (2022) describe burnout from masking social rules. If social and communication items really sit together, teaching both at once—instead of splitting them—could lower overload and spare clients from burnout later.
Why it matters
When you write goals, group social and communication targets under one umbrella. Treat repetitive and sensory needs as a separate plan. This cleaner split can make data paths clearer, reduce team confusion, and maybe catch burnout risk sooner.

03Original abstract
Research continues to try and pinpoint the etiological role of particular genes and brain structure in autistic spectrum disorder (ASD), but despite a host of biological, genetic and neuropsychological research, the symptom profile of pervasive developmental disorders (PDDs) are not yet linked to etiological theory. Debate continues around whether or not there is one single dimension that incorporates the three criteria domains of social difficulties, communication deficits and repetitive or restrictive interests and behaviours as a unitary 'ASD' concept, or whether PDD as they are currently described represent the co-occurrence of separate sub-domains of developmental difficulties. Although the three criteria need to be met for a diagnosis of PDD to be made, the association between them remains unclear. This review highlights that the majority of the literature that looks at the triad of impairments suggests the symptom structure does not match that proposed by diagnostic manuals, and that the triad may no longer fit as the best way to conceptualize ASD.
