Background and study aims
Autism is a lifelong condition that affects the way that a person communicates and relates to others. It is a spectrum condition, which means that the level of disability is spread across a wide range, from almost unnoticeable to completely debilitating. In general however, the difficulties sufferers experience tend to fall into social communication (speech and body language), social interaction (recognising and expressing emotions) and social imagination (being able to understand and predict other people’s behaviour). Children with autism often find it difficult to transfer skills learned in one setting to another. A previous study (the Preschool Autism Communication Trial, PACT) showed that in a clinical setting it was possible to help improve communication between parents and child however these improvements were less obvious in other settings. The aim of this study is to test ways to transfer the child’s communication gains into everyday home and education settings.
Who can participate?
Autistic children aged between 2 and 11 years.
What does the study involve?
This project is split into two phases. In the first phase, all participants receive the PACT-G therapy. This therapy involves coaching the parents in ways of interacting with their child. This takes place over a number of sessions, and is accompanied by sessions in educational settings (preschool or school) with educational staff. This part of the project is to find out whether schools are able take part and how easy it is to recruit participants for the study. In the second phase of the project, participants are randomly allocated to one of two groups. Those in the first group take part in the PACT-G therapy and those in the second group continue as usual, with no additional therapy. Children are assessed, and parents and teachers complete a number of questionnaires at the start, middle (7 months) and end (11 months) of the treatment.
What are the possible benefits and risks of participating?
Participants may benefit from improved communication abilities within different settings. There are no notable risks involved with taking part in this study.
Where is the study run from?
The study is run by University of Manchester and takes place in participants' homes and schools across Newcastle, Manchester and London (UK)
When is the study starting and how long is it expected to run for?
February 2016 to July 2019

Scientific title | Paediatric Autism Communication Trial – Generalised (PACT-G) |
Study objectives | External pilot phase: The aim of the external pilot phase is to: 1. Demonstrate schools’ willingness and ability to engage with the study 2. Demonstrate the ability to recruit and retain participants Full randomised controlled trial: The aim of this study is to test an intervention designed systematically to promote generalisation of previously demonstrated clinic-assessed treatment gains into home and school contexts. Hypotheses: 1. The intervention will show the added efficacy and cost-effectiveness of preschool and school-age autism outcomes in home, school and research settings compared to treatment as usual 2. There will be an increase in the generalisation of acquired communication across contexts and persons, shown by mediation and the mechanistic study |

Intervention | External pilot phase: All participants receive the PACT-G therapy (see below) Randomised controlled trial: Participants are randomised to receive the PACT-G therapy (see below) or treatment as usual. Both groups will have a pre-randomisation baseline assessment, a mid-point (after approx 7 months) and end-point assessment (after approx 11 months). Detail of the PACT-G intervention PACT-G therapy is an enhancement of the original clinic-based PACT therapy. This is a ‘parent-mediated’ therapy in which caregivers are coached, using video-feedback, to interact with their child using evidence-based strategies that facilitate communication development in the child. Parent sessions: Parents will receive 12 intervention sessions. Prior to starting the intervention, a home visit is conducted to introduce the intervention to the parents, explore the family context and set expectations. Where feasible the first two sessions are delivered in a clinic, allowing the parent to learn early strategies in a controlled environment with a set of toys specially selected to facilitate interaction. Subsequent sessions are a mix of home based sessions and Skype/telephone-delivered consultation. Each parent session begins with a discussion of progress made since the last session. The parent and therapist then watch a 5-minute video, either a video made by the therapist of the parent and child in play or a parent-made video of a home based routine, such as mealtime. The therapist facilitates the parent to identify actions that lead to child communication and to adopt PACT-G strategies in their interaction with the child. Parents are assisted to set goals for themselves, based on the interaction strategies discussed. They are asked to practice these daily, initially in a half hour ‘special time’, but eventually during naturalistic opportunities throughout the day. Education setting sessions: Therapy in the educational setting begins 1 - 2 months after the parent has commenced therapy, with a start time integrating into the school term schedule. In the education setting PACT-G sessions will be delivered to trained learning support assistants (LSA), who are additional staff with a specific remit to attend to the child’s special needs and thus with dedicated individual time in the classroom or nursery. LSAs and other education staff receive an initial training session to introduce them to PACT-G therapy. The education-based intervention then consists of therapist-LSA sessions that mirror the therapist-parent sessions in the home. Videos are made of the LSA and the child and are used to coach the LSA in the use of appropriate PACT-G strategies. The LSA then implements these with the child daily in class time. There are 12 therapist-LSA sessions over 6 months, alternating in-school visits and skype/telephone consultation. PACT-G strategies will also be integrated in a complementary way with other communication strategies that may already be in use in the school. Collaboration between parent and educational staff: Importantly, the separate therapeutic work with parents and LSAs described above will be supplemented with a schedule of joint parent-LSA meetings to support the work and ensure consistent use of strategies across home and education settings. The meetings will use the manualised technique of ‘Structured Conversation with Parents’ (SCP). Meetings are structured around ‘explore’, ‘focus’, ‘plan’ and ‘review’ stages, which allow the LSA and parent to share experiences and maximize intervention consistency. |

Primary outcome measure | External pilot phase: 1. School engagement rate is determined by the total number of schools which have signed up to participate at the end of pilot phase, i.e. 6 months 2. Family recruitment rate is determined by the total number of families which have consented up to participate at the end of pilot phase, i.e. 6 months Main randomised controlled trial: Efficacy of the PACT-G therapy, which is assessed at mid-point (approx 6 - 8 months) and end-point (approx 11 months), with exact assessment tools to be determined during the external pilot phase. |
