While there is some evidence that ToM , or a precursor skill , can be taught to people with ASD , there is little evidence of maintenance of that skill , generalisation to other setting s , or developmental effects on related skills .
It is possible that the continuing refinement of the ToM model will lead to better interventions which have a greater impact on development than those investigated to date
BACKGROUND The ' Theory of Mind ' ( ToM ) model suggests that people with autism spectrum disorder ( ASD ) have a profound difficulty underst and ing the minds of other people - their emotions , feelings , beliefs , and thoughts .
As an explanation for some of the characteristic social and communication behaviours of people with ASD , this model has had a significant influence on research and practice .
It implies that successful interventions to teach ToM could , in turn , have far-reaching effects on behaviours and outcome .
OBJECTIVES To review the efficacy of interventions based on the ToM model for individuals with ASD .
Randomized Controlled Caregiver Mediated Joint Engagement Intervention for Toddlers with Autism
This study aim ed to determine if a joint attention intervention would result in greater joint engagement between caregivers and toddlers with autism . The intervention consisted of  24 caregiver-mediated sessions  with follow-up 1 year later . Compared to caregivers and toddlers r and omized to the waitlist control group the immediate treatment ( IT ) group made significant improvements in targeted areas of joint engagement . The IT group demonstrated significant improvements with medium to large effect sizes in their responsiveness to joint attention and their diversity of functional play acts after the intervention with maintenance of these skills 1 year post-intervention . These are among the first r and omized controlled data to suggest that short-term parent-mediated  interventions can have important effects on core impairments in toddlers with autism .
