Plain English Summary

Background and study aims
Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by atypical social communication and interaction, and repetitive and restricted behaviours, activities and interests, affecting around 1% of the general population worldwide. It is estimated that about 30% of children with ASD do not develop functional speech, and remain non-verbal or minimally verbal even after years of speech, language and educational interventions. Although a wide range of programmes have been developed for treating language impairments in ASD, none has been effective in eliciting functional speech in ASD children. This study aims to develop a set of multifaceted, individualized, easily implemented, music-assisted intervention programmes (MAP) to increase spoken language ability in 2-4-year-old, nonverbal or minimally verbal children with ASD. Specifically, we will develop a structured training protocol, delivered through naturalistic strategies and interactive activities, to teach language to ASD children through songs and music making. Randomised controlled trials (RCTs) will be conducted to assess and validate the effectiveness of our intervention programmes through the comparison of the outcomes of the treatment group (who receives music-assisted language interventions) with a control group (who receives traditional speech and language therapy).

Who can participate?
We are recruiting nonverbal or minimally verbal children with a clinical diagnosis of autism spectrum disorder, aged between 2 and 4 years, to take part in this study.

What does the study involve?
To take part, participants and their parents/guardians/carers will need to visit our lab or a clinic room in the School of Psychology and Clinical Language Sciences at the University of Reading. Each visit will take under 2 hours, and will include breaks and snacks. Participants will be asked to do one or more of the following tasks during their visit:
1. Take part in a formal interview with a trained researcher
2. Complete a hearing screening test, a short IQ test, and receptive and expressive language tests
3. Take part in language interventions for 18 weeks (two 45-min sessions per week)

All these tasks use speech, music, or environmental sounds, or everyday items and situations, which are not emotionally stressful or scary. Some parts of the tasks such as those involving speaking, singing, and/or imitation of speech/song materials, will be recorded on audio. Some parts of the tasks such as the interview and intervention sessions will be recorded on video.

What are the possible benefits and risks of participating?
Participants are likely to benefit from being in this research study since they will be given language interventions. Through this Proof of Concept project, we aim to develop a novel set of music-assisted programmes (MAP) to provide an easy-to-implement, individualised treatment for language impairments in nonverbal or minimally verbal ASD children in a relaxing, comforting, and stimulating setting. The project outcomes have the potential to break new ground and open up new possibilities for language and communication interventions in ASD. Parents/guardians/carers can receive a copy of the final report once it has been published in a peer-reviewed journal as well as a non-technical summary of the results should they wish.

There are no or only minimal risks involved in our intervention programmes, such as possible fatigue, anxiety, or frustration. We will endeavour to make the sessions enjoyable, engaging, and fun for our participants. Participants can take as many breaks as necessary during the sessions. Parents/guardians/carers will be present during all sessions, and they can choose to terminate their children’s participation at any point.

Where is the study run from?
The study will be run in the School of Psychology and Clinical Language Sciences at the University of Reading.

When is the study starting and how long is it expected to run for?
The project runs from 01/09/2019 to 31/08/2021 (updated 04/11/2020, previously: 28/02/2021). RCTs will run for 18 weeks.

Who is funding the study?
This project is funded by a European Research Council Proof of Concept Grant (ERC-POC-2018, 838787, MAP, 2019-2021, to Fang Liu (PI).

Scientific title

Music-assisted programmes: Developing communication in autism spectrum disorder through music making



Study hypothesis

Autistic children in the treatment group (who receives music-assisted language interventions) will achieve better outcomes than those in the control group (who receives traditional speech and language therapy).

Ethics approval

Approved 20/03/2019, the University of Reading Research Ethics Committee (Academic and Governance Services, Whiteknights House, Whiteknights, PO Box 217, Reading RG6 6AH; +44 (0)118 378 7119;, ref: UREC 19/07.

Study design

This study will involve a randomised controlled trial, in which children will be offered either a music-assisted language intervention or treatment as usual (speech and language therapy).

Autism spectrum disorder


Everyone agreeing to take part will have a 50:50 chance of receiving the music-assisted (MAP) intervention or treatment as usual (TAU). A computer will be used to allocate participants (stratified for gender) randomly to one of the study arms, which will not have any identifying information about the participants apart from gender.

After assessing the receptive and expressive language level of each participant, 36 target words will be chosen for all participants to learn during the intervention sessions. These target words will relate to naturalistic, everyday activities that the child spontaneously engages in, so the adult can follow the child’s lead or focus of attention and the child’s activities can be turned into a social routine, with music.

All intervention sessions will be videotaped, individually delivered in a quiet room. Each intervention session will last about 45 minutes, happening 2 days a week, for 18 weeks. For the music-assisted (MAP) language interventions, we will use a structured protocol, delivered through naturalistic strategies such as incidental learning, high-density repetition, time-delay and mand-modelling. For each of the 36 target words, we will create a set of songs defining its meaning and the contexts where it occurs. During each session, the songs will be delivered using a digital piano or a guitar, and a range of music instruments commonly used in music therapy. The children will be taught to sing the songs, where the target words will be occurring repetitively, together with other engaging and interactive activities such as dancing, vocalizing, improvising, and playing musical games. For the treatment-as-usual (TAU) control group, regular speech and language therapy sessions will be delivered, focusing on the learning of the 36 target words using conventional methods, in line with the PACT approach (Green et al., 2010) and the NICE guideline on psychosocial interventions (

Intervention type



Drug names

Primary outcome measure

The production of 36 target words is assessed by a blinded outcome data assessor at baseline, post-intervention, and 1-month follow-up.

Secondary outcome measures

1. IQ is measured using Mullen Scales of Early Learning, 1995 at baseline, post-intervention, and 1-month follow-up.
2. Receptive and expressive language is measured using Receptive and Expressive One-Word Picture Vocabulary Tests, Fourth Edition; ROWPVT-4, EOWPVT-4 at baseline, post-intervention, and 1-month follow-up.
3. ASD symptomatology is measured using the ADOS-2 at baseline, post-intervention, and 1-month follow-up.
4. Vocal production throughout 3 days is measured using audio recordings at baseline, post-intervention, and 1-month follow-up.

Age group




Target number of participants

We anticipate to include 30 2-4-year-old, nonverbal or minimally verbal children with ASD in our randomised controlled trials (RCTs), 15 in the treatment group and 15 in the control group. This would be a sufficient number for our proof of concept study. However, considering the possible attrition and drop-out of the participants, we aim to recruit 50 participants at the outset.

Participant exclusion criteria

1. A neurodevelopmental disorder of known etiology (e.g., fragile X syndrome).
2. Significant sensory or motor impairment.
3. Major physical problems such as a chronic serious health condition.
4. Seizures at time of entry.
5. Use of psychoactive medications.
6. History of a serious head injury and/or neurologic disease.
7. Alcohol or drug exposure during the prenatal period.
8. Ratio IQ below 35 as measured by mean age equivalence score/chronological age on the visual reception and fine motor subscales of the Mullen Scales of Early Learning (Mullen, 1995).
