Dr. 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]. Studies made an average of 5.4 statistical comparisons on psychosocial outcomes, ranging from 115 comparisons. This poses a severe threat to the validity of findings as group differences in outcomes could be caused by underlying differences in certain demographics or characteristics and cannot be confidently attributed to the presence of the assistance dog. A total of 13 mental health outcomes were assessed in which 4 (31%) were significant across group or condition. Naturalistic Observation: Definition, Examples, Pros and Cons Limitations and Benefits of Psychological Research on Animals Many people see animal testing as a cruel and inhumane practice. The study of nonhuman animals has actually played a huge role in psychology, and it continues to do so today. Overall, studies addressed an average of 62% of methodological consideration items with a range of 23% (3/13) to 100% (15/15; denominators were variable as there were two items not applicable to all study designs). To achieve the first aim of the reviewto describe study characteristicswe extracted several features of from each study and article (Table 1). Other studies assessed outcomes from hearing dogs (7/27; 26%), guide dogs (4/27; 15%), and medical alert/response service dogs (2/27; 7%). Most studies (24/27; 89%) assessed outcomes from a single type of assistance dog (e.g. The third aim of the review was to summarize psychosocial outcomes of studies. After removing duplicate articles in EndNote following a validated protocol [23], articles were screened based on their title and abstract. First, only 59% of studies stated whether ethical approval for human subjects was sought and received. 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. A common argument against the use of animals in experiments is that animals are not good models for humans, based on the observation that we are not simply larger versions of lab rats - our bodies (and minds) work differently. Animal research continues to play a vital role in psychology, enabling discoveries of basic psychological and physiological processes that are important for living healthy lives. [14] which found significantly higher internal locus of control 6-months after receiving a mobility service dog. Researchers who study nonhumans recognize that their studies may involve certain harms that can range from the relatively minor (e.g., drawing a blood sample) to the more serious (e.g., neurosurgery). Study designs included both cross-sectional and longitudinal studies, with only one randomized longitudinal study identified [14]. Many scientists study animal behavior because it sheds light on human beings. The search strategy was adapted to the other databases, including mapping terms to each databases thesaurus or prescribed vocabulary, as appropriate. In fact, nine new articles were identified (three theses, six publications) that had been published since the last review on this topic in 2012 [9]. Studying other species often avoids some of the complex ethical problems involved in studying humans. Following PRISMA guidelines, a systematic review was conducted across seven electronic databases. alerting or responding to medical crises such hypoglycemia or seizures), and individuals with mental health disorders (e.g. As with every experimental methodology, there are disadvantages to using animals in experiments. 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. Research on non-human primates, for instance, continues to offer valuable perspectives into the causes and evolution of individual, social, and reproductive human actions. Grey literature was addressed by searching ProQuest Dissertations and Theses (ProQuest) and WorldCatDissertations and hand searching the abstracts of the International Society for Anthrozoology and International Association of Human Animal Interactions Organizations conferences. Three studies using SF-36 failed to find significant effects on the social domain; Lundqvist et al. Therefore, detailed descriptions of study populations is critical for helping the field understand for whom assistance dogs are beneficial regarding social, emotional, or psychological health and under what contexts or conditions [74]. Register for the early bird rate. Research in the field of human-animal interaction (HAI) and assistance dogs is not only rapidly growing but is often disparately published across multidisciplinary journals and outlets. BBC - Ethics - Animal ethics: Experimenting on animals For full functionality of this site, please enable JavaScript. However, positive findings were found in depression using the POMS by a different study [13]. Promising areas include psychological wellbeing, emotional wellbeing, and social participation in which several positive outcomes were identified. Therefore, the current literature is limited to correlational, rather than causal conclusions regarding the benefits of assistance dogs on the psychosocial health of their owners. If it does, then it can be tested on humans with a lower risk of a negative outcome. Competing interests: The authors have declared that no competing interests exist. 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). However, three studies collapsed analyses across several types of assistance dogs and impairments. Discuss the Strengths and Weaknesses of the Use of Animals for The three Rs are: Reduction, Refinement . Thus, this pattern may be better explained by the file drawer effect in which there is a bias towards publishing positive findings over null findings [79]. The use of animal models in behavioural neuroscience research Conducting periodic systematic reviews of this research is crucial to both disseminate knowledge as well as to identify knowledge gaps for future studies [20]. Second, only 63% of studies described inclusion and/or exclusion criteria of recruited participants, and some studies did not report all demographic or disability characteristics of participants. All articles were screened by two independent reviewers (authors KR and JG) using Covidence systematic review software (Veritas Health Innovation, Melbourne, Australia). The only other positive outcome was from Allen et al. However, inclusion and exclusion criteria were less commonly described (17/27; 63%). 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 . A final potential reason for outcome discrepancies is variation in methodological rigor across studies. found significantly lower depression and anxiety using the POMS and GHQ-30, respectively, 6-months after receiving a hearing dog [13]. Regarding social participation, 14 comparisons were made in which 4/14 were significant (29%). Marguerite E. OHaire, Affiliation: Future research will benefit from stronger methodological rigor and reporting to account for heterogeneity in both humans and assistance dogs as well as continued high-quality replication. Using other standardized measures of independence, Matsunaka & Koda [42] found that those with guide dogs reported and lower stress while being mobile. Most animals, once the testing process has been completed, are euthanized. [16] found that those with a mobility or medical service dog reported significantly higher work/school functioning than a control group. Disadvantages of Animal Experimentation Ethical concerns Animals have to die for our research May be considered to be cruel Animal testing may not be acceptable regarding religious aspects Humans should not play god Animal testing can be expensive Animal experimentation may lead to the development of new diseases May be done in an excessive manner 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. Using the occupation domain of the CHART, Rintala et al. route finding, retrieving dropped items, alerting to a seizure), the assistance dogs companionship, emotional and social support, and social facilitation effects in public may be particularly salient to improving the quality of life of individuals with disabilities [79]. [32] reported no relationship between the mobility domain and having a service dog or hearing dog. 29 Major Pros & Cons Of Animal Testing - E&C However, on different measures of social functioning Rodriguez et al. Summary of methodological rating scores by each of the N = 27 individual studies. This variation in assessment times makes it difficult to draw definitive conclusions on conflicting findings. [35] found increased functioning 3-months after receiving a mobility, hearing, or medical service dog, while Shintani et al. 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 . Guest [13] used the Profile of Mood States Scale [POMS; 51], finding less overall mood disturbance, less tension, and less confusion 3-months after hearing dog placement. Data Availability: All relevant data are within the paper and its Supporting information files. Similarly, Crudden et al. The authors concluded that although results are promising, conclusions drawn from the results must be considered with caution [9]. In total, 147 comparisons were made across the 27 studies that examined the effect of having an assistance dog on a standardized scale or sub-scale on a psychosocial outcome: 58 (39%) psychological outcomes, 43 (29%) social outcomes, 34 (23%) quality of life outcomes, and 12 (8%) energy/vitality outcomes. Animal experimentation, also called animal testing, has contributed to many important scientific and medical discoveries. While both reviews found mostly positive findings regarding mobility, guide, and hearing dogs effects on their handlers health and wellbeing, social interactions, and activity participation [7, 8], it was concluded that the small number of studies and methodological limitations of these studies preclude any clear conclusions [8]. 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. Top 112 + Disadvantages of animal studies in psychology The effects of assistance dogs on psychosocial health and - PLOS To compare methodological rigor by study design, an independent t-test was used to compare mean scores across longitudinal and cross-sectional designs. 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. Service dogs can assist individuals with physical disabilities (e.g. Advancing psychology to benefit society and improve lives. (2017, January 1). Secondly, many studies did not report sufficient detail in results in terms of estimates of variability and effect size. 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]. The authors found three studies reporting an association between having a seizure alert or response dog and improvements to quality of life and wellbeing, concluding a need for more research. Overall, sample sizes were higher than what is usually observed in targeted animal-assisted intervention studies with dogs (e.g. Research has indicated that beyond the physical or tangible benefits that an assistance dog is trained to provide (e.g. Regarding sleep, Guest found better self-reported sleep quality 3- and 12-months after receiving a hearing dog while Rodriguez et al. For example, organizations that place assistance dogs may have housing, familial, physical, or even financial requirements for potential recipients that should be subsequently reported in the manuscript to fully define the population. 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. The most commonly studied type of assistance dog was mobility service dogs, followed by hearing dogs. 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. 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. [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. 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). 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]. Why is animal psychology important? How Comparative Psychologists Study Animal Behavior - Verywell Mind 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). Of 34 total quality of life outcomes, 9 (26%) were positive (improved or better quality of life in comparison to pre- or control conditions), 22 (65%) were null (no difference) and 3 (9%) were negative (decreased or worse quality of life in comparison to pre- or control conditions). The remaining studies were quasi-experimental in that they did not use randomized assignment to treatment or control groups. [16] found no difference in sleep disturbance between individuals with mobility or medical service dog and a control group. The main reason why they are inaccurate is because of the huge differences between humans and animals. 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. These 18 studies recruited study populations with a range of physical impairments including para- or quadriplegia, musculoskeletal disorders, and neuromuscular disorders. Although this tendency occurs in many fields, the file-drawer bias may especially be prevalent in human-animal interaction research due to the preconceived notion that animals are beneficial for humans [80]. Another early review published by Sachs-Ericsson and colleagues in 2002 [8] summarized 14 quantitative studies on both standardized and nonstandardized outcomes following mobility service dog or hearing dog placement (omitting guide dogs). Compared to those on the waitlist, individuals with an assistance dog report better psychosocial functioning and wellbeing [16, 17].
