Comparison of contingent and noncontingent access to therapy dogs during academic tasks in children with autism spectrum disorder

Autistic sociality: challenging representations of autism and human-animal interactions

PURPOSE

The objective of this synthesis research was to explore representations of autism and human-animal interactions (HAI) in the health sciences literature and the implications for autistic children and their families.

METHODS

Guided by critical interpretive synthesis methods proposed by Dixon-Woods et al. (2006), we synthesized and examined how autism and HAI were described in the health sciences literature and explored assumptions and goals underlying HAI as an intervention.

RESULTS

Across 47 reviewed articles, animals were represented as therapeutic objects whose purpose from a biomedical perspective was to address "problematic" behaviours and "deficits" in social functioning and development. HAI was employed as a therapy to address improvements in these problematic behaviours in the majority of studies. Relational and social aspects of HAI were present but not explicitly discussed. An alternative perspective proposed by Olga Solomon positioned autistic sociality as one form of diverse human socialities that can be embraced, rather than held problematic and in need of being normalized.

CONCLUSIONS

Implications for HAI in rehabilitation include recognizing the multiple purposes of animals in a child's life, not only the therapeutic goal of normalizing functioning.

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.

Advancing Methods in Animal-Assisted Intervention: Demonstration of Starting Points in Clinical Practice for Children with Autism Spectrum Disorder

Therapy animals have been frequently included in interventions for children with autism spectrum disorder (ASD); however, direct and systematic procedures such as assessing preference for and reinforcing efficacy of the animals are rarely conducted. Assessing preference for stimuli is valuable when determining how to make interventions for children with ASD most effective. We conducted paired-stimulus preference assessments and follow-up reinforcer assessments to determine if a therapy dog might be an effective reinforcer. We found one third of participants preferred the dog the least, one third of participants moderately preferred the dog, and one third of participants highly preferred the dog relative to other stimuli. Furthermore, we found preference predicted reinforcing efficacy for five of six participants. We suggest clinicians systematically conduct assessments to clearly identify the role of the therapy animal, to improve quality of, and demonstrate efficacy of interventions including animals for clinical populations.

Animal-assisted Interventions as an Adjunct to ABA Services: Clinician Practices and Perceptions

Although the popularity of animal-assisted interventions (AAI) continues to increase, an examination of these practices among clinician populations that may incorporate AAI in their clinical services are largely absent from the literature. This study examined the practices and desirability of incorporating animals into ABA services. A total of 544 ABA clinicians completed a web-based survey. Data revealed respondents not only considered incorporating animals into ABA services (n = 307), but almost 20% (n = 107) also reported engaging in this practice. Dogs were reported as the most frequently incorporated animals and an examination of animal sources and prior training revealed substantial variability. Animal incorporation practices were viewed as desirable, feasible, and a majority of respondents reported being interested in AAI implementation. Implications of these results beget a discussion about potential adverse consequences to clients and clinicians that participate in these practices. This discussion includes physical safety risks, financial threats, and potential Behavior Analysis Certification Board (BACB) code violations. Animal welfare concerns, which are often omitted from discussions about AAI, are also discussed to inform clinicians of the added responsibilities that need to be considered. In total, survey results and the accompanying discussion should urge ABA clinicians to pause when considering the incorporation of animals into their clinical practices. No published articles could be found that examine the use of animal incorporation practices within the area of clinical ABA services. Personal and professional risks and animal welfare concerns associated with the utilization of these practices, as identified in this study, should inform programmatic decision-making by clinical practitioners and supervisors interested in engaging in these practices. Results of this survey highlight the potential need for modifications to professional standards and ethical codes of the BACB and state licensing authorities. As this is a novel area of investigation, this article illustrates the need for further empirical evaluation of animal-assisted interventions as an adjunct to ABA services.

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.

The Research of Standardized Protocols for Dog Involvement in Animal-Assisted Therapy: A Systematic Review

Dogs are considered the most important species involved in animal-assisted therapy (AAT), and the scientific literature focuses on the benefits linked to the involvement of dogs in various therapeutic areas. In this study, we carried out a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, exploring the scientific literature from the last 5 years (2016-2021) on three databases (PubMed, Scopus, and Web of Science) to highlight the characteristics of the dogs involved in AATs. Based on the scientific literature relevant to such dogs, we considered different parameters (i.e., number, age, sex, breed, temperament, methods of choice and training, health status, research goals, and activities with dogs) to include studies in our paper. After screening 4331 papers identified on the searched databases, we selected 38 articles that met the inclusion criteria. Analysis of the included articles showed that the characteristics of the dogs were neglected. Our findings indicated a lack of information about the dogs, as well as the absence of standardized and univocal criteria for dog selection, training programs, and health protocols.

Evaluating preference for and reinforcing efficacy of a therapy dog to increase verbal statements

The purpose of this study was to evaluate preference for and reinforcing efficacy of a therapy dog to increase verbal statements across different contingencies. Five children with autism spectrum disorder ages 3-8 years participated. Alternating treatments and reversal designs were used to compare conditions in which (a) a therapy dog was not present, (b) access to a therapy dog was noncontingent, (c) access to a therapy dog was contingent on interacting with a therapist, and (d) access to another preferred item was contingent on interacting with a therapist. Results varied across participants. Noncontingent access to the therapy dog slightly increased verbal statements for 1 participant. Contingent access to the therapy dog increased social interactions for 2 participants; however, this was the most effective intervention for only 1 participant. Practitioners should be aware that some clients may be better suited for interventions including therapy dogs than others.

Using Principles from Applied Behaviour Analysis to Address an Undesired Behaviour: Functional Analysis and Treatment of Jumping Up in Companion Dogs

The aim of this study was to investigate the feasibility and effectiveness of procedures successfully used in human related applied behaviour analysis practices to the field of clinical animal behaviour. Experiment 1 involved functional analyses to identify the reinforcement contingencies maintaining jumping up behaviour in five dogs. Experiment 2 comprised teaching dog owners a noncontingent reinforcement intervention (i.e., time-based reinforcement) via behavioural skills training. Single-case experimental methods were implemented in both experiments. The results of Experiment 1 showed that access to a tangible (dogs D01, D02, D03, and D04) and owner attention (dog D05) were reliably maintaining the jumping up behaviour. Experiment 2 demonstrated that noncontingent reinforcement effectively reduced jumping in three out of four dogs (Tau -0.59, CI 90% [-1-0.15], p = 0.026, Tau -1, CI 90% [-1--0.55], p = 0.0003, and Tau -0.32, CI 90% [-0.76-0.11], p = 0.22 for dyads D01, D02, and D05, respectively), and that behavioural skills training was successful in teaching owners to perform a dog training intervention with high fidelity. Although the results are promising, more canine-related research into functional analysis and noncontingent reinforcement, as well as implementation of behavioural skills training with animal caregivers, is needed.

Pharmacological, non-pharmacological and stem cell therapies for the management of autism spectrum disorders: A focus on human studies

In the last decade, the prevalence of autism spectrum disorders (ASD) has dramatically escalated worldwide. Currently available drugs mainly target some co-occurring symptoms of ASD, but are not effective on the core symptoms, namely impairments in communication and social interaction, and the presence of restricted and repetitive behaviors. On the other hand, transplantation of hematopoietic and mesenchymal stem cells in ASD children has been shown promising to stimulate the recruitment, proliferation, and differentiation of tissue-residing native stem cells, reducing inflammation, and improving some ASD symptoms. Moreover, several comorbidities have also been associated with ASD, such as immune dysregulation, gastrointestinal issues and gut microbiota dysbiosis. Non-pharmacological approaches, such as dietary supplementations with certain vitamins, omega-3 polyunsaturated fatty acids, probiotics, some phytochemicals (e.g., luteolin and sulforaphane), or overall diet interventions (e.g., gluten free and casein free diets) have been considered for the reduction of such comorbidities and the management of ASD. Here, interventional studies describing pharmacological and non-pharmacological treatments in ASD children and adolescents, along with stem cell-based therapies, are reviewed.
