Specific and Non-specific Factors of Animal-Assisted Interventions Considered in Research: A Systematic Review

How to Measure Human-Dog Interaction in Dog Assisted Interventions? A Scoping Review

Human-dog interaction is the working tool through which the therapeutic, educational and recreational goals of dog-assisted interventions (DAIs) are achieved. A better understanding of the characteristics of this interaction could improve the effectiveness of DAIs. This scoping review addresses the question: how has the human-dog connection been measured in the context of DAIs? After searching the Web of Science and Scopus platforms, only peer-reviewed, primary research studies reporting measures of therapy dog-human interaction, relationship and bond were included. A total of 70 included articles provided information on what was measured (interaction, relationship or bond) and how, as well as the general context (DAIs or experimental situations with therapy dogs). While the majority of the articles identified use behavioural analysis methods to analyse the interaction between the participant/recipient and the therapy dog during DAIs, it was possible to identify some more structured tools that assess the participant/recipient's interaction, relationship or bond with the therapy dog, as well as tools that consider the animal's perspective or focus on the dog-handler dyad, indicating growing areas of research. The tools and methods identified can be used by both practitioners and researchers to further explore aspects of human-dog interaction in the field of DAIs.

Dog-assisted interventions for adults diagnosed with schizophrenia and related disorders: a systematic review

Background

Many individuals diagnosed with schizophrenia and related disorders experience insufficient symptom relief from currently available treatment options. Researching additional venues should be prioritized. This systematic review, designed in accordance with PRISMA, examined the effect of targeted and structured dog-assisted interventions as a supplementary treatment.

Methods

Randomized as well as non-randomized studies were included. Systematic searches were conducted in APA PsycInfo, AMED, CENTRAL, Cinahl, Embase, Medline, Web of Science, and in several sources covering "gray" (unpublished) literature. In addition, forward and backward citation searches were performed. A narrative synthesis was conducted. Quality of evidence and risk of bias were assessed in accordance with GRADE and RoB2/ROBINS-I criteria.

Results

12 publications from 11 different studies met eligibility criteria. Overall, studies showed diverging results. General psychopathology, positive and negative symptoms of psychosis, anxiety, stress, self-esteem, self-determination, lower body strength, social function, and quality of life were among the outcome measures with significant improvement. Most documentation for significant improvement was found for positive symptoms. One study indicated significant deterioration of non-personal social behavior. The risk of bias was high or serious for most of the outcome measures. Three outcome measures were associated with some concerns regarding risk of bias, and three with low risk of bias. Quality of evidence was graded low or very low for all outcome measures.

Conclusions

The included studies indicate potential effects of dog-assisted interventions for adults diagnosed with schizophrenia and related disorders, mostly beneficial. Nevertheless, low number of participants, heterogeneity, and risk of bias complicate the interpretation of results. Carefully designed randomized controlled trials are needed to determine causality between interventions and treatment effects.

Survey of international academic centers and institutes focused on human-animal bond: Scope and landscape in 2021

Routine surveying of academic centers focused on the human-animal bond is critical to understand the trajectory of the field and to create an environment where centers can learn from one another and build collaborations. The purpose of this manuscript was to report the findings of a survey of these human-animal bond centers, to summarize the status of the field, and to identify changes within the field since 2016. Survey questions concentrated on the demographic characteristics, engagement programs, educational opportunities, and research focuses of the centers. Findings suggest that the field continues to grow as one-third of human-animal bond centers are less than 10 years old. The number of centers that participated in this survey increased by 31% compared to the previous survey (O'Haire et al., 2018). Centers have developed a variety of engagement programs, including animal-assisted intervention and companion animal education programs. About half of the centers (48%) offer degree programs and about one quarter of the centers (24%) offer certificate programs. Most centers (95%) focus their research on companion animals with the most studied companion animal being dogs (95%). The most frequent data collection method was surveys (86%). Qualitative analyses, behavior measures, and physiological measures were also common. The most notable changes from the 2016 survey include overall growth of the field (indicated by the establishment of new centers) and a shift in the specialty area of directors, moving from 44% of directors being veterinarians in 2016 survey to 90% having a human-focused specialty in the 2021 survey. Most centers' research focused on animal-assisted interventions which is consistent with the previous survey. As the field of the human-animal bond continues to grow and more centers emerge, ongoing evaluation of offerings is important to track changes, identify needs, and foster success.
