The small number of studies included in the present study limited the ability to make inferences when comparing the three models and investigating the strengths and weaknesses of each type of intervention with respect to important outcomes .
Since the outcome of ' reciprocity of social interaction towards others ' could be a dependent variable that might be context -bound to interactions with the child 's parent , we can not conclude the interventions for pre-school children with ASD have significant effects on a generalized skill to engage in reciprocal interactions with others .
However , the outcomes of ' reciprocity of social interaction towards others ' and ' parental synchrony ' may be promising targets for interventions involving pre-school children with ASD .
BACKGROUND There has an increasing number of published trials on psychosocial intervention programmes for pre-school children with autism spectrum disorder ( ASD ) .
To achieve better quality of unbiased evidence for the effectiveness of ASD interventions , it is necessary to conduct a comprehensive review that covers studies with adequate quality st and ards , such as r and omised controlled trials ( RCTs ) , and different types of intervention In this study , we categorize interventions for ASD as behavioural , social-communication focused , and multimodal developmental based on Howlin 's classification of early interventions for children with ASD .
The aim of this study was to compare these three models and investigate the strengths and weaknesses of each type of intervention and to identify the approaches that contribute to a successful outcome for children with autism .
The Home TEACCHing Program for Toddlers with Autism
The study evaluated the efficacy a parent training intervention for children with autism based on the TEACCH model . Twenty families were r and omly assigned to the treatment or waitlist group . All families were compared at pre- and post-treatment on formal dependent measures . Direct measures of behavior were compared across six matched pairs using a multiple baseline probe design . The results of the multiple baseline design showed robust support for improvement in child and parent behavior . Due to the sample size and short time frame , results of a repeated measures analysis of variance did not reach significance
