Plain English Summary

Background and study aims
The vast majority of children with Autism Spectrum Disorders (ASD) live in low and middle-income countries and have no access to effective interventions or services. Most of the researches in interventions for ASD that work have been conducted in richer countries with relatively large numbers of ASD specialist therapists. One of the best-researched interventions, in which parents are trained to help their children communicate, has been found to work very well in the UK (the PACT intervention). The aim of this study is to adapt this intervention carefully so that it can be used by parents of children living in low-income countries. Furthermore, because there are very few specialists in these settings, the study will explore the impact of the delivery of the intervention by trained and supervised non-specialists.

Who can participate?
Children aged 2-9 years with an Autism Spectrum Diagnosis.

What does the study involve?
The study will have three phases. In the first phase, we will talk to parents who have children with ASD, about their experiences. We will also talk to people who may have tried to help these parents and their children and to local experts who are involved in developing services for children. Using this information, the team from the UK will work with local experts to make necessary changes to the intervention so that it can work in these south Asian settings.
In the second phase we will test the PASS communication intervention to find out if it works, by delivering it to 30 children with ASD and comparing them to another 30 children who will not receive the intervention. The children, who will be recruited from Goa and Rawalpindi, will be randomly allocated into treatment and control groups in such a way each child has an equal chance of being in either group. We will analyse the effects after 8 months and one year by carrying out a number of tests for parent-child interaction, the child’s social functioning.
In the third phase, we will analyse the results of our study and publish them through conferences and papers for journals. We feel this project is important because it aims to develop an intervention that has the potential to be used by many families in poor communities; it uses our expertise of simplifying interventions so they can be delivered by non-specialists; and because it has the potential for being taken up at a larger scale by health planners.
What are the possible benefits and risks of participating?
All families in this study (i.e. those in both the intervention and non-intervention groups) will have detailed assessments from skilled professionals and will have feedback about the results of these. The research team will be in touch with all families regularly through the study to find out how they are progressing and to hear their experiences. Half of the families involved will receive the PASS communication intervention which may be helpful to children and families. The results of this study should assist in the development of autism treatments throughout the UK.
There is a time commitment requirement on behalf of families. Otherwise we do not anticipate that this study will result in any disadvantages or risks to families.

Where is the study run from?
The project will be conducted in Goa, India and Rawalpindi, Pakistan, sites situated in a region with the highest number of children and the greatest unmet need for interventions in autism.

When is the study starting and how long is it expected to run for?
The study started in March 2013 and will run till April 2014.

Study information

Scientific title

Parent-mediated Intervention for Autism Spectrum Disorders in South Asia: A two-site two-arm single-blinded randomised controlled trial



Study hypothesis

The aims of this exploratory RCT will be to test:
1. The feasibility and acceptability of the implementation of intervention and trial design in South Asian settings
2. The success of the “task-shifting” approach (use of community health workers to deliver the intervention) in delivering fidelity to the intervention model
3. The effectiveness of the adapted model in replicating treatment effects found in the UK PACT intervention – allowing power estimation for further large trials

Autism Spectrum Disorders


Intervention: 30 children will receive an adaptation of the parent-mediated video-aided communication-focussed PACT (Pre-school Autism Communication Therapy) approach, a theory-based, relatively low intensity, manualised intervention and evidenced in the PACT trial (Green et al 2010)

Control: 30 children will receive routine care for children with ASD
