Verbal Interactional Synchronization between Therapist and Children with Autism Spectrum Disorder during Dolphin Assisted Therapy: Five Case Studies

Animal-Assisted Interventions for Autism Spectrum Disorder: A Systematic Review of the Literature from 2016 to 2020

In the last five years, the literature on animal-assisted intervention (AAI) for Autism Spectrum Disorder (ASD) has doubled in size from 42 studies prior to 2015 to 85 studies (cumulative total assessed in 2020). Horses remain the most commonly researched animal for AAI, followed by dogs. The most commonly researched outcome was social interaction, across 21 studies. Though the quantity of studies has increased, issues with methodological rigor remain. Results highlight the need for a continued focus on methodological rigor as well as refining the structure of animal-assisted interventions, addressing the welfare needs of the animals involved, and continuing to establish an evidence base of both significant and nonsignificant findings for AAI for individuals with ASD.

Terapias y actividades asistidas con animales para niños con TEA: un estudio de revisión

Este trabajo incluye una revisión de la literatura publicada entre 2010 y 2019 que aborda la efectividad de las Terapias y Actividades Asistidas con Animales como intervención con niños y adolescentes con Trastorno del Espectro Autista (TEA). Se realizó una búsqueda bibliográfica en PsycINFO, PsycARTICLES, ProQuest, ERIC y Google Scholar, empleando los términos [(animal assisted therapy OR animal assisted intervention OR dog-assisted therapy OR equine-assisted therapy OR dolphin-assisted therapy) AND (autism OR ASD)]. Se identificaron 245 estudios, de los cuales se seleccionaron 40 con base en diferentes criterios de inclusión, tales como que las intervenciones descritas tengan un enfoque psicoeducativo y sean evaluadas mediante instrumentos rigurosos. En cada uno de ellos se revisaron las variables analizadas, los instrumentos de evaluación utilizados, las características de cada intervención y los resultados obtenidos. Los resultados sugieren que los animales más utilizados son el caballo y el perro, y que este tipo de intervención tiene efectos positivos para niños con TEA en áreas como la interacción y la comunicación social, el comportamiento y el desarrollo motor, entre otros. Se concluye que es una intervención beneficiosa para niños y adolescentes con autismo, aunque siempre como complemento de otro tipo de tratamientos.

Non-Parametric Evaluation Methods of the Brain Activity of a Bottlenose Dolphin during an Assisted Therapy

Simple Summary

Dolphin Assisted Therapies (DAT) can be used with any person or group with specific needs and it can be as disparate as people at risk of social exclusion, eating disorders, terminally ill, mental health disorders, among many others. This paper is focused on measuring and analyzing dolphins brain activity when DAT is taking place, in order to identify if there is any differences in female dolphin’s neuronal signal when it is interacting with control or intervention subjects. In addition, we designed a wireless and portable electroencephalographic single-channel signal capture device to monitor the brain activity of a female bottle-nose dolphin. Our findings also validate the evidence that the interaction between a patient with a certain disease or disorder and undergoes to a DAT modifies usual brain activity behavior of a female bottle-nose dolphin.

Abstract

Dolphin-Assisted Therapies (DAT) are alternative therapies aimed to reduce anxiety levels, stress relief and physical benefits. This paper is focused on measuring and analyzing dolphins brain activity when DAT is taking place in order to identify if there is any differences in female dolphin’s neuronal signal when it is interacting with control or intervention subjects, performing our research in Delfiniti, Ixtapa, Mexico facilities. We designed a wireless and portable electroencephalographic single-channel signal capture sensor to acquire and monitor the brain activity of a female bottle-nose dolphin. This EEG sensor was able to show that dolphin activity at rest is characterized by high spectral power at slow-frequencies bands. When the dolphin participated in DAT, a 23.53% increment in the 12–30 Hz frequency band was observed, but this only occurred for patients with some disease or disorder, given that 0.5–4 Hz band keeps it at 17.91% when there is a control patient. Regarding the fractal or Self-Affine Analysis, we found for all samples studied that at the beginning the dolphin’s brain activity behaved as a self-affine fractal described by a power-law until the fluctuations of voltage reached the crossovers, and after the crossovers these fluctuations left this scaling behavior. Hence, our findings validate the hypothesis that the participation in a DAT of a Patient with a certain disease or disorder modifies the usual behavior of a female bottle-nose dolphin.

Third time's the charm or three strikes you're out? An updated review of the efficacy of dolphin-assisted therapy for autism and developmental disabilities

CONTEXT

Dolphin-assisted therapy (DAT) is a popular form of animal-assisted therapy for autism spectrum disorders and other psychological conditions.

OBJECTIVE

In this review, our third, we analyze the most recent DAT studies in terms of construct and internal validity criteria to determine if there is empirical support for DAT.

METHOD

To ensure a systematic review, we searched for peer-reviewed studies on DAT by submitting relevant search terms to Google Scholar from 2007 to 2020, conducted a further search of all DAT papers in several peer-reviewed journals, and reviewed reference sections of DAT articles to ensure a thorough review of the literature between 2007 and the present.

RESULTS

The DAT literature continues to be marked by several weaknesses in both internal and construct validity that preclude confident inferences regarding the intervention's efficacy.

CONCLUSION

There is still insufficient evidence that DAT has therapeutic value.

Changes in behavioural synchrony during dog-assisted therapy for children with autism spectrum disorder and children with Down syndrome

BACKGROUND

Dog-assisted therapy (DAT) is hypothesized to help children with autism spectrum disorder (ASD) and Down syndrome (DS).

METHODS

The present authors compared synchronous movement patterns of these children (n = 10) and their therapy dogs during the first and last session of a DAT programme, and their post-therapy changes in emotional and behavioural problems.

RESULTS

The present authors found a significant increase in synchrony between child and therapy dog over time. Exploratory analyses suggest more synchrony between children with ASD and their therapy dogs, compared to the children with DS.

CONCLUSIONS

This study is the first to test the synchrony hypothesis, shedding light upon a mechanism that may underlie the effect of DAT and how this may be different for children with ASD and DS.

Evaluating Animal-Assisted Interventions: An Empirical Illustration of Differences between Outcome Measures

Simple Summary

This study compares and contrasts several outcome measures to assess the effect of an equine-assisted intervention for a child with Autism Spectrum Disorder. Before and after the equine-assisted sessions, we conducted a semi-structured interview with the participant’s parents, asked parents to fill out a general screening instrument separately, and observed the participant’s social and communication skills during five equine-assisted sessions. We found differences between the interview and questionnaire with regard to parents’ perceptions of aggression regulation and interacting with peers. Differences with regard to parental reports and observations were found for play development and anxiety. The observations provided a detailed view of the child’s development during the intervention, which yielded an interesting hypothesis in terms of the current dose–response discussion in AAI for children with Autism Spectrum Disorder.

Abstract

Multiple authors have called for strong empirical evaluations to strengthen the foundation of Animal-Assisted Interventions. Carefully choosing the outcome measures of these studies is important, as choosing the wrong outcomes may lead to a failure to detect effects. The current study therefore compares and contrasts the use of several outcome measures, to assess the effect of an equine-assisted intervention for a child with Autism Spectrum Disorder: (1) a semi-structured interview with both parents, specifically designed for children with cognitive disabilities, (2) a general screening instrument filled out by both parents separately, which can be used to assess children’s psycho-social problems, and (3) systematic observations of social and communication skills during the equine-assisted sessions. All instruments indicated an improvement in the participant’s social and communication skills. We found differences between the interview and questionnaires with regard to parents’ perception of aggression regulation and interacting with peers. Differences with regard to parental reports and observations were found for play development and anxiety. The observations provided a detailed view of the child’s development during the intervention, which yielded an interesting hypothesis in terms of the current dose–response discussion in AAI for children with Autism Spectrum Disorder.
