Animal-assisted interventions

This is a brief overview of information about animal-assisted interventions, taken from the Autism CRC report, Interventions for children on the autism spectrum: A synthesis of research evidence (Autism Interventions Evidence Report).

There are seven other category overviews available to help people learn about different interventions and their research evidence. To understand the information in its full context, we encourage you to access the full report.

Why are animal-assisted interventions supposed to support children's development?

Animal-assisted interventions involve interactions with animals as the primary means for supporting skill development. These interventions are based on the premise that human-animal interactions may be motivating for children on the autism spectrum, and provide a calming and non-judgemental environment within which social abilities and general wellbeing may improve^1-3.

While physiological benefits have also been proposed for certain animal-assisted interventions^3,4, the primary focus has typically been on the promotion of psychosocial health and wellbeing.

How are these interventions used in clinical practice?

The most prominent use of animal-assisted interventions for children on the autism spectrum has been through the use of assistance dogs (also called, canine assisted therapy), therapeutic horse riding (also called, equine-assisted therapy), and dolphin therapy². In some cases, intervention is delivered via the animal (e.g., therapeutic horse riding), whereas in other applications, animals form part of enrichment activities or education programs.

Animal-assisted interventions are described using a variety of terminology and there is little standardisation in relation to intervention characteristics including the person delivering the intervention (e.g., therapist, animal handler) and consistency of procedures⁵.

What are the principles that underpin the use of animal-assisted interventions?

Because of the wide variety of uses of animal-assisted intervention, there is no universal set of principles that are shared across all practices. In Australia, the Delta Institute which acts as an accrediting body for dog trainers, has published Best Practice Guidelines⁶ that outline member expectations including, but not limited to:

• Appropriate training qualifications relating to the use of animals in therapy.
• Provision of appropriate and ethical services.
• The need for continuing professional development.

Who delivers these interventions?

Children on the autism spectrum often have needs across multiple domains of learning, and physical and mental health. Accordingly, children and families may benefit from the expertise of a range of clinical practitioners spanning health, education and medical disciplines.

For all intervention categories, it is essential that clinical practitioners have acquired appropriate qualifications, are regulated (e.g., by a professional or government body), and deliver interventions that are within their scope of practice. A detailed explanation is provided in the full report.

What is the evidence for the effect of animal-assisted interventions on child and family outcomes?

Below is a summary of the evidence for the effect of animal-assisted interventions on child and family outcomes, taken from systematic reviews published since 2010. This means that a range of relevant individual studies have been considered, and thus reflects the best available evidence at this point in time.

Listed first are findings from systematic reviews that considered a mixture of animal-assisted interventions. Following that are findings relating to specific animal-assisted intervention practices.
