However, even within a single category, there are differences in assistance dog breeds, temperaments, and training that may significantly contribute to observed variance across studies.

Longitudinal studies addressed an average of 59% of methodological items while cross-sectional studies averaged 65%. Disadvantages of animal studies in psychology, are the finest-quality pictures of lovely, adorable animals that we have gathered for you and Friend. Animal psychologists have been undergoing an identity crisis, with increasingly common criticisms of the traditional field revolving around the assumption that laboratory preparations alone will reveal laws of learning having generality. Limitations and Benefits of Psychological Research on Animals Many people see animal testing as a cruel and inhumane practice. Of 58 total psychological outcomes, 21 (37%) were positive (improved or better psychological health in comparison to pre- or control conditions), 37 (63%) were null (no difference), and zero (0%) were negative (decreased or worse functioning in comparison to pre- or control conditions). The principle disadvantage with animal experiments is the problem of generalisability. We can also ask and answer certain questions that would be difficult or impossible to do with humans. One of the first reviews published by Modlin in 2000 [7] summarized nine published quantitative and qualitative studies on the benefits of guide dogs, hearing dogs, and mobility service dogs on their handlers (omitting unpublished theses). A main weakness of animal studies is that animals have a different physiology to humans. In the self-evaluation subcategory, 5/19 (26%) outcomes found a significant effect of having an assistance dog on standardized measures of self-esteem, self-concept, and other measures of self-evaluation. However, more than half of all studies (16/27; 59%) had sample sizes greater than or equal to N = 50. Using the occupation domain of the CHART, Rintala et al. First, only 59% of studies stated whether ethical approval for human subjects was sought and received. Other countries where studies took place included Canada (3), Japan (2), New Zealand (1), and Sweden (1). Lundqvist et al. Part of that approval process requires the scientist to identify whether there might be less invasive ways to do the same thing. To date, there have been several reviews summarizing the literature on the psychosocial effects of assistance dogs on their handlers. e0243302. t, F, or B values) and only 55% (15/27) of studies reported exact probability values from analyses. The authors concluded that although results are promising, conclusions drawn from the results must be considered with caution [9]. Finally, in discussion sections, most studies (22/27; 81%) stated at least two limitations of their study. After removing duplicate articles in EndNote following a validated protocol [23], articles were screened based on their title and abstract. However, it is of note that several methodological weaknesses of the studies make it difficult to draw any definitive conclusions, including inadequate reporting and a failure to account for moderating or confounding variables. For example, without any animal research, effective treatments for human conditions like Alzheimers disease may very well be found, but it would certainly take decades longer to find them, and in the meantime, millions and millions of additional people would suffer. Other studies found increased social connectedness 3-months after receiving a mobility or hearing dog [31] and increased community integration 6, 12, 18, and 24 months after receiving a mobility service dog [14]. Included studies assessed psychosocial outcomes via standardized measures from assistance dogs that were trained for functional tasks related to a physical disability or medical condition (omitting psychiatric service dogs or emotional support dogs). The scientific rigor of each study was rated according to a 5-level system while the methodological quality of each study was scored on a 7-point scale. The other five studies found no effect of having a mobility service dog [32], hearing dog [29, 32], or guide dog [38] on life satisfaction using SWLS. [32] found that participants reported worse occupational functioning 7-months after receiving a hearing dog while Davis [44] found that individuals with a mobility service dog reported worse occupational functioning compared to a control group. Regarding sleep, Guest found better self-reported sleep quality 3- and 12-months after receiving a hearing dog while Rodriguez et al. As research on the assistance animal-handler relationship continues to increase, there is a need for an updated, comprehensive collation of the literature encompassing studies on the effects of all varieties of assistance dogs (guide dogs, hearing dogs, and both mobility and medical service dogs) including both published studies and unpublished theses and dissertations. Data from 5,191 children were included in the study; 2,236 lived in homes with a dog or cat, and 2,955 lived in households that did not include any animals. Grayson D.S., Bliss-Moreau E., Machado C.J., Bennett J., Shen K., Grant K.A., Fair D.A., Amaral, D.G. Of 27 studies, 20 (74%) assessed a psychological outcome with a total of 24 different standardized measures. The final sample included 24 articles (12 peer-reviewed publications, 12 unpublished theses/dissertations) containing 27 individual studies. Future research should focus on assessing outcomes from these medical alert and response assistance dogs and how their roles may be similar or different than mobility, guide, or hearing dogs.
Limitations of Animal Tests - Humane Society International The use of animal models in behavioural neuroscience research A study protocol was designed a-priori to define the search strategy, inclusion and exclusion criteria, and items for data extraction. Of 5 studies that used the mental health domain of the SF-36 or the shorter 12-Item Short Form Health Survey (SF-12), only Shintani et al. For example, we know what the connections are between the amygdala and other brain regions, but how does activity in the amygdala affect brain functioning? Of 147 comparisons, 44 (30%) were positive (improved or better functioning in comparison to pre- or control conditions), 100 (68%) were null (no observed difference), and 3 (2%) were negative (decreased or worse functioning in comparison to pre- or control conditions). Importantly, only a few comparisons were made in the negative direction (2%) indicating that there is limited reason to believe that acquiring an assistance dog is associated with worse functioning. The third aim of the review was to summarize psychosocial outcomes of studies. However, when more than one few companies uses the same resources and provide competitive parity are also known as rare resources. In terms of general social functioning, 2/10 comparisons made were significant. [15] found no difference in self-esteem, adequacy, or competency over 12-months following receiving a mobility service dog. He is the former associate director for research at the Primate Center, a past president of the American Society of Primatologists, a recipient of the Patricia R. Barchas Award in Sociophysiology from the American Psychosomatic Society, a fellow of several professional societies, and in 2012, he received the Distinguished Primatologist Award from the American Society of Primatologists. However, three studies collapsed analyses across several types of assistance dogs and impairments. Animal models are a fundamental tool in the life sciences. In the economic domain of the CHART, which assesses socio-economic independence, Davis [44] again found that those with a mobility service dog reported worse economic functioning than controls while two mobility dog studies reported null findings [30, 41].

Psychology Research: Psychological Research on Animals Oversight and inspection of facilities is provided by the U.S. Dept. Using a different measure of emotional functioning, Rodriguez et al. This pattern suggests a potential publication bias present in which disproportionately more positive findings are in the published studies than the unpublished theses [78]. The discussion section aims to review the findings from each aim and to provide targeted suggestions for future research. In the sub-category of independence, a total of 20 comparisons were made in which 9 (45%) were significant, but 3 (15%) were in the negative direction. The below discussion considers various potential explanations for the inconsistencies in findings across studies. Even procedures as simple as drawing a blood sample or testing an animal on a cognitive task must be approved by the local IACUC before the work can begin. PLOS is a nonprofit 501(c)(3) corporation, #C2354500, based in San Francisco, California, US. Inconsistencies in findings were discussed in terms of wide variability in assessment times, interventions, measures, and rigor, and recommendations were made to contribute to the knowledge of this growing application of the human-animal bond. Methodological rigor also did not significantly correlate with year of publication (r = 0.327, p = 0.096) nor total sample size (r = 0.258, p = 0.194). [17] found no difference among mobility service dog users compared to controls. The electronic searches were performed on July 23, 2018, and updated on January 23, 2019. [16] found higher emotional functioning in those with a mobility or medical service dog compared to a control group. In a few instances, they represent the only reasonable approach. Many scientists study animal behavior because it sheds light on human beings. Even if we accept evolutionary psychology, humans have evolved to be very different from most other animals, perhaps all other animals. The three Rs. However, Lundqvist et al. However, Guest et al. The main reason why they are inaccurate is because of the huge differences between humans and animals. The rationale for excluding studies on emotional service dogs and psychiatric service dogs is that the primary benefits of these dogs are psychological in nature, rather than physical or medical, which complicated comparisons of their psychosocial effects. Of 27 studies, 15 were cross-sectional and 12 were longitudinal. Part of the justification for why nonhuman animals are studied in psychology has to do with the fact of evolution. Animal experimentation, also called animal testing, has contributed to many important scientific and medical discoveries. Nine studies assessed self-esteem as a primary outcome, with four studies [14, 32, 36, 46] finding a significant effect of having a guide, hearing, mobility, or medical service dog on self-esteem as measured by the Rosenberg Self Esteem Scale [RSES; 53]. Although outcomes from assistance dog placement for children and adolescents have been quantified with qualitative [e.g., 6971] and observational [e.g., 72] study designs, effects on standardized measures of psychosocial wellbeing including social functioning have not been explored. Can you really generalise results from animals to humans? The most common provider organizations represented were Canine Companions for Independence (CCI; six mobility service dog studies), Paws with a Cause (four mobility service dog studies), and Hearing Dogs for Deaf People (HDDP; four hearing dog studies). For example, the benefits of an assistance dog for a socially isolated individual who experiences periodic anxiety and depression may be significantly different than an individual without these characteristics. The latter offers a more cynical take on animal welfare, namely that. A total of 13 mental health outcomes were assessed in which 4 (31%) were significant across group or condition. This is the result of a new study led by researchers at the University of Mannheim and the Max Planck Institute for Human Development in Berlin Fig 2 displays the total scores across each of the 15 items, separated by introduction, methods, results, and discussion sections (see S2 Table for individual study scores). We also planned to extract or manually calculate effect sizes to create funnel plots to investigate potential publication biases.
Case study advantages and disadvantages. Case Study Advantages and However, a recent 2018 review summarized five published quantitative studies describing outcomes from seizure alert and seizure response service dogs. S1 Table. However, other studies reported no relationship between having a mobility service dog and self-esteem via the RSES [39, 41] or other standardized measures of self-esteem [15, 28, 36]. In addition to the different human and dog phenotypes that contribute to this heterogeneity, there are likely differences in the strength of the human-animal bond and attachment relationships formed between assistance dogs and handlers [19, 76]. Longitudinal studies have found that individuals report improvements to their emotional wellbeing, social functioning, and quality of life just 3 to 6 months after receiving an assistance dog [1315]. Of 15 cross-sectional studies that surveyed individuals who owned assistance dogs for variable periods of time, 4/15 studies (27%) considered length of time of assistance dog ownership as a potential explanatory or moderating variable in analyses. But, was then later tested on a human and the human died. Visual display of methodological ratings for N = 27 studies ordered by the number of studies addressing each item. A majority of studies (18/27; 67%) assessed outcomes from mobility service dogs for individuals with physical disabilities. One author argued that an important methodological issue is the absence of appropriate measures in measuring the effect of an assistance dog on recipients lives [32]. Last updated 22 Mar 2021. [45] found higher health-related quality of life among those with a mobility service dog compared to a control group, but not among those with a hearing dog. When reporting statistical results, 78% of studies (21/27) provided estimates of variability for outcomes, including confidence intervals, standard deviations, or standard error of the mean.
The Sad Truth About Pet Ownership and Depression - Psychology Today As the assistance dog itself is the key component of the intervention, details regarding the dogs breeding, rearing, selection, and training, as well as the assistance dog-handler matching process are critical to disentangling potential mechanisms [75]. Seven studies (26%) had sample sizes less than or equal to N = 20, all of which were longitudinal. PLoS ONE 15(12): For example one could not look at the effects of maternal deprivation by removing infants from their mothers or conduct isolation experiment on humans in the way that has been done on other species. Therefore, future efforts should be made to publish null findings in peer-reviewed journals and to encourage scientific transparency [80]. The concept of a Regional Innovation Ecosystem (RIE) has gained significant attention in the academic literature and policy arena in recent years [1,2].Based on the inspiration of the natural ecosystem, the RIE was first introduced by Moore in 1993 as a framework for understanding the dynamics of innovation within a specific region [].The RIE can be considered analogous to a natural ecosystem . In the mobility domain, only Milan [41] found a significant effect of having a mobility service dog on the CHART mobility domain (which includes hours per day out of bed and days per week out of the house) while Davis [44] and Rintala et al. Cruelty in Entertainment Disaster Response Companion Animals Dogfighting Dog and Cat Welfare Dog Meat Trade Farm Animals Animal Agriculture and Climate Change Factory Farming Plant-Based Eating Wildlife Fur Human-Wildlife Coexistence Rhino and Elephant Protection Seal Slaughter Shark Finning Trophy Hunting Whaling Wildlife Trade Other Ways We Help Answer and Explanation: See our A-Level Essay Example on The studies carried out by Milgram, Piliavin, Haney and Gardner & Gardner, have unearthed some very important as well as surprising details about human behaviour and experience which in nearly all situation affects it., Social Psychology now at Marked By Teachers. Two of the most well-known animal studies were conducted by Konrad Lorenz and Harry Harlow. Additionally, research suggests the relationship between an assistance dog and its owner may also serve as a reciprocal attachment and caregiving relationship characterized by secure and strong attachments [18, 19]. In the 1950s research which used animal subjects to investigate early life experiences and the ability for organisms to form attachments contributed significantly to the field of developmental psychology. Overall, sample sizes were higher than what is usually observed in targeted animal-assisted intervention studies with dogs (e.g. This research aimed to conduct a systematic assessment of the current state of knowledge regarding the potential benefits of assistance dogs on standardized outcomes of the health and wellbeing of individuals with disabilities.
29 Major Pros & Cons Of Animal Testing - E&C It is unreasonable to assume that the changes to an individuals life following receipt of an assistance dog is identical for all ages, gender identities, backgrounds, and disabilities. In parallel with an increasing amount of research quantifying the therapeutic benefits of companion dogs and therapy dogs on human health and wellbeing [5, 6], there has been an increased focus on quantifying the physical, psychological, and social effects that assistance dogs may have on their handlers [79].

Jane K. Yatcilla, Funding: The authors received no specific funding for this work. In longitudinal studies, the first follow-up time point varied from 3- to 12-months after receiving an assistance dog. This systematic review identified 24 articles containing 27 studies that assessed a psychosocial outcome of having an assistance dog (guide dog, hearing dog, mobility service dog, or medical service dog).
The effects of assistance dogs on psychosocial health and - PLOS A total of 254 records were screened via full text, of which 230 were excluded. Capitanios research interests are focused on developing naturally-occurring nonhuman primate models of psychological processes, in order to better understand the underlying biology of phenomena such as loneliness, inhibited temperament and poor social functioning. Table 4 summarizes the social outcomes across studies within the sub-categories of general social functioning, loneliness, and social participation. Equally important is the consideration of the potential harms to humans of not doing the research. Apprehension around burgeoning medical research in the late 1800s and the first half of the 20 th century sparked concerns over the use of humans and animals in research , .Suspicions around the use of humans were deepened with the revelation of several exploitive research projects, including a series of medical . Therefore, future studies are warranted that specifically assess health and wellbeing using validated parent-proxy or self-report measures to fully understand the potential effects that assistance dogs can have on children and adolescents with disabilities. First, there may be ceiling effects present whereby individuals are functioning at initially healthy levels of the measured construct (e.g., depression, self-esteem) prior to receiving an assistance dog and thus may not significantly improve on these measures. Future studies should provide detailed researcher-specified criteria for participation as well as organizational-specified criteria for placing/receiving an assistance dog, if applicable. Kerri E. Rodriguez, In the next sub-category, six studies assessed life satisfaction outcomes using Satisfaction with Life Scale [SWLS; 57]. If you've taken an introductory psychology class, then you have probably read about seminal psychological research that was done with animals: Skinner's rats, Pavlov's dogs, Harlow's monkeys. Studies on psychiatric service dogs, emotional support dogs, and pet dogs were excluded. Study designs included both cross-sectional and longitudinal studies, with only one randomized longitudinal study identified [14]. In fact, positive, null, and negative findings are equally instrumental in understanding the complexities of the role that assistance dogs play in the lives of individuals with physical disabilities. The rhesus monkey connectome predicts disrupted functional networks resulting from pharmacogenetic inactivation of the amygdala. An important finding from this review was that most positive findings were reported in published studies, while unpublished theses were more likely to report null findings. Interestingly, only one included study [16] assessed outcomes from participants under the age of 18.
Comparative Psychology - Simply Psychology [35] found higher health-related quality of life 3-months after receiving a mobility, hearing, or medical service dog on one of three measures used [EuroQol Visual Analog Scale; 56]. Probably not, in much the same way that nonhuman research that permitted a significant human study to be conducted is rarely described in todays textbooks. mobility or guide), thus restricting human participants to a single category of impairments.
Naturalistic Observation: Definition, Examples, Pros and Cons Positive outcomes included significant effects of having an assistance dog on psychological wellbeing, emotional functioning, self-esteem, and vitality. While results described positive effects of service dogs in terms of social, psychological, and functional benefits for their handlers, it was concluded that all 12 of the studies had weak study designs with limitations including lack of comparison groups, inadequate description of the service dog intervention, and nonstandardized outcome measures. [66, 67]) but smaller than that of pet dog research [68]. This page has been archived and is no longer being updated regularly. [14] which found significantly higher internal locus of control 6-months after receiving a mobility service dog. Most articles were published in the 2010s, indicating an increasing publication interest in this topic over time. In other contexts, dogs can be specially trained to provide specific benefits to individuals with impairments, disabilities, or chronic conditions as trained assistance animals. The remaining studies were quasi-experimental in that they did not use randomized assignment to treatment or control groups. However, only 44% (12/27) of studies reported statistical values (e.g. Most longitudinal studies (8/12) assessed participants at two time points: at baseline prior to receiving an assistance dog, and an average of 5.8 +/- 3.3 months after participants received an assistance dog (range of 312 months follow-up). Conducting periodic systematic reviews of this research is crucial to both disseminate knowledge as well as to identify knowledge gaps for future studies [20]. purpose-bred from a provider, self-trained) and breeds (e.g., Labrador Retriever, Golden Retriever, Mixes). This systematic review summarized the current state of knowledge regarding the effects of owning an assistance dog (including service, guide, hearing, and/or medical alert or response dogs) on standardized outcomes of psychosocial health and wellbeing of individuals with disabilities. In terms of emotional functioning, two studies found positive results using the SF-36 role emotional domain; Lundqvist et al. The replicated measures identified in this review can serve as a basis for future researchers to collate the existing literature when making assessment choices. Importantly, unpublished theses had a similar average sample size as published studies, with similar power to detect effects compared to published studies. Secondly, many studies did not report sufficient detail in results in terms of estimates of variability and effect size. [17] found an effect of having an assistance dog on mental health. 2016 Jul 20;91(2):453-66. The CES-D asks participants to rate how often they had experienced 20 depressive symptoms in the prior week using statements such as I thought my life had been a failure, while the POMS asks participants to rate from not at all to extremely how they feel right now using single words such as sad and unhappy. It is also possible that some standardized measures do not capture the intended effects from having an assistance dog. Two studies from the a single thesis [29] made the remaining 14 comparisons on measures of loneliness distress and complementary loneliness, finding no significant changes to loneliness six months after receiving a hearing dog and no significant group differences in loneliness compared to those without a hearing dog.
Scholarly Articles on Animal Experimentation: History, Legislation Promising areas include psychological wellbeing, emotional wellbeing, and social participation in which several positive outcomes were identified. Our objective was to identify, summarize, and methodologically evaluate studies quantifying the psychosocial effects of assistance dogs for individuals with physical disabilities. Future research is necessary to determine if in fact some measures are inappropriate to measure change following an assistance dog, which may be addressed using interviewing and focus group techniques among assistance dog handlers.
