Visual display of methodological ratings for N = 27 studies ordered by the number of studies addressing each item. Continued efforts are required to improve methodological rigor, conduct replicable research, and account for heterogeneity in both humans and animals to advance the state of knowledge in this field. 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. However, on different measures of social functioning Rodriguez et al. 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. They have advantages and disadvantages compared with other approaches. 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. The sub-category of loneliness had 19 comparisons in which only 1/19 (5%) was significant. Other studies found no effect of having a mobility service dog on quality of life including more specific measures such as physical and environmental quality of life [33, 34]. Most animals, once the testing process has been completed, are euthanized. Table 4 summarizes the social outcomes across studies within the sub-categories of general social functioning, loneliness, and social participation. The specific aims were to (1) describe the key characteristics of studies (2) evaluate the methodological rigor of studies (3) summarize outcomes. Top 112 + Disadvantages of animal studies in psychology Methodological weaknesses including poor reporting of assistance dog interventions and statistical limitations prevent any clear conclusions made regarding the psychosocial effects of assistance dogs on individuals with disabilities. Summary of vitality outcomes across studies ordered by sub-category, then by standardized measure. As with every experimental methodology, there are disadvantages to using animals in experiments. 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]. Exclusions included those based on population, outcomes, and methodology. The deprived monkeys became unable to integrate socially, unable to form attachments, and were severely emotionally disturbed. Discuss the Strengths and Weaknesses of the Use of Animals for Animal Studies Of Attachment: Lorenz And Harlow - Psychology Hub A total of 30% of comparisons made were positive in which having an assistance dog was associated with improved psychosocial functioning among individuals with disabilities. Articles were extracted for information based on three aims to describe study characteristics, assess methodological rigor, and summarize outcomes. In addition to poor methodological reporting, many studies were restrained by statistical weaknesses. A main weakness of animal studies is that animals have a different physiology to humans. Of the 100 null comparisons, 43 (43%) were from published papers and 57 (57%) were from unpublished theses. Studies were eligible for inclusion if they met the following criteria: (1) The study population consisted of current or prospective owners/handlers of an assistance dog (including service, guide, hearing, and/or medical alert or response dogs) with a physical disability or chronic condition in which the assistance dog is trained to do work or perform tasks directly related to the disability or condition [4]; (2) The study collected original data on the effect of the assistance dog on their handler with at least one psychosocial outcome, including those quantifying aspects of mental health, social health, and health-related quality of life; and (3) The psychosocial outcome(s) were collected via a standardized measure tested for validity and reliability. After removing duplicate articles in EndNote following a validated protocol [23], articles were screened based on their title and abstract. Ethical and Scientific Considerations Regarding Animal Testing - PLOS For full functionality of this site, please enable JavaScript. However, results suggested that for most outcomes, having an assistance dog had no effect on psychosocial health and wellbeing. A health information specialist (JY) constructed and executed comprehensive search strategies in six electronic databases: MEDLINE (PubMed platform), Cumulative Index to Nursing and Allied Health Literature (CINAHL) (EBSCOhost platform), ERIC (EBSCOHost), Web of Science Core Collection (Web of Science), PsycINFO (EBSCOhost), and PsycARTICLES (EBSCOhost). Rintala et al. Of 27 studies, 7 (26%) reported outcomes from at least one standardized measure of vitality with a total of five different standardized measures. Our search procedure identified 24 articles containing 27 studies assessing psychosocial outcomes from a wide variety of human and assistance dog populations. However, none of the four studies using the Center for Epidemiologic Studies Depression Scale [CES-D; 52] found significant differences in self-reported depression among those with a mobility service dog compared to a control group [3941] or after 4-months with a mobility service dog [28]. 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]. 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. Of the 44 positive comparisons, 36 (82%) were from published papers and 8 (18%) were from unpublished theses. After receiving an assistance dog, individuals retrospectively report increases to their social, emotional, and psychological health [e.g., 1012]. Summary of quality of life outcomes across studies ordered by sub-category. Animal models are a fundamental tool in the life sciences. Even if we accept evolutionary psychology, humans have evolved to be very different from most other animals, perhaps all other animals. r/psychology How to get your children to eat more fruits and vegetables: Children will eat more fruits and vegetables if families take more time to eat meals. Advantages & Disadvantages | a2-level-level-revision, psychology In the case of disagreements, inclusion or exclusion was resolved by discussion and consultation with a third independent reviewer (author MO). Marguerite E. OHaire, Affiliation: [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. 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. Studies are often described without specifying that they were animal studies. But, was then later tested on a human and the human died. Average age across all studies was 42 +/- 13 years old. Summary of psychological outcomes across N = 27 studies ordered by sub-category, then by standardized measure. However, more than half of all studies (16/27; 59%) had sample sizes greater than or equal to N = 50. Unfortunately, many introductory textbooks dont give the full picture of animal research. Author KR then coded 100% of articles. This practice was instrumental in our evolution and in the emergence of civilization. Finally, most studies (21/27;78%) compared outcomes to a control or comparison condition. The remaining four longitudinal studies assessed participants 35 times with final follow-up ranging from 924 months after receiving an assistance dog. Seven studies (26%) had sample sizes less than or equal to N = 20, all of which were longitudinal. Using the CHART, both Milan [41] and Davis [44] found no group differences in social integration among those with a mobility service dog control groups. However, 2 studies found worse occupational functioning in terms of employment, schooling, or homemaking. Therefore, in the cases where positive outcomes were reported in these studies, it is unknown what amount of time with an assistance dog the finding was associated with (and therefore difficult to compare to findings from other studies). Similarly, Crudden et al. A final potential reason for outcome discrepancies is variation in methodological rigor across studies. Of 27 studies, 20 (74%) assessed a psychological outcome with a total of 24 different standardized measures. The most commonly studied type of assistance dog was mobility service dogs, followed by hearing dogs. Jamie Greer, Using a different measure of emotional functioning, Rodriguez et al. 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.

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). The most notable weaknesses included a lack of adequate reporting in the methodological sections, which not only limits interpretation of findings but prevents reproducibility. Within cross-sectional studies, number of years since first partnering with an assistance dog ranged from 6-months to 45 years with means ranging from 29 years. Part of the justification for why nonhuman animals are studied in psychology has to do with the fact of evolution. Measures of the same outcome not only can have different wording and items, but also can measure functioning over different time periods or contexts. doi:10.1371/journal.pone.0243302, Editor: Geilson Lima Santana, University of Sao Paulo Medical School, BRAZIL, Received: July 22, 2020; Accepted: November 18, 2020; Published: December 2, 2020. Animal research: Serving a vital role in psychological science. Vassar College, Poughkeepsie, New York, United States of America, Affiliation: Because of the broad inclusion criteria, the 27 studies were widely varied in terms of human and dog participants, assessment time points, statistical analyses, and standardized outcomes. Answer and Explanation: Specifically, this review sought to systematically identify, summarize, and evaluate studies assessing psychosocial outcomes from owning an assistance dog (including service, guide, hearing, and/or medical alert or response dogs) with measures tested for reliability and validity among individuals with physical disabilities. 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. Summary of methodological rating scores by each of the N = 27 individual studies. 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]. This occurred by either matching groups on select criteria or statistically comparing groups demographic characteristics before performing main analyses. 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. In terms of general social functioning, 2/10 comparisons made were significant. Funding: The authors received no specific funding for this work. In addition, null findings were reported on standardized measures of family role 3-, 6-, and 12-months after receiving a mobility service dog [15], discrimination and social inclusion 12-months after receiving a mobility service dog [34], and family and social self-concept among mobility dog users compared to a control group [37]. Animal models are used in experiments in the behavioural neurosciences that aim to contribute to the prevention and treatment of cognitive and affective disorders in human beings, such as anxiety and depression. Naturalistic Observation: Definition, Examples, Pros and Cons To achieve the third aim of the reviewto summarize outcomespsychosocial outcomes within each study were extracted. 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. In longitudinal studies, the first follow-up time point varied from 3- to 12-months after receiving an assistance dog. To be sure, each species has its own specializations that enable it to fit into its unique ecological niche; but common ancestry results in structural (e.g., brain) and functional (e.g., memory) processes that are remarkably similar between humans and nonhumans. Advantages Useful Findings. Purdue University Libraries, Purdue University, West Lafayette, Indiana, United States of America. Six studies used standardized measures to assess general health and health symptoms, three of which [17, 28, 35] reported null findings on the general health domain of the RAND 36-Item Short Form Health Survey [SF-36; 47]. 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). Secondly, many studies did not report sufficient detail in results in terms of estimates of variability and effect size. Can you really generalise results from animals to humans? Moderator analyses will be useful in determining the potential explanatory effects that handler-service dog relationships have on psychosocial outcomes. Thorough reporting in terms of the magnitude and variability of effects observed will allow researchers to make informed comparisons across populations and interventions and conduct critically needed meta-analyses in the field. 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? 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, 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 particular, not only did studies vary largely in terms of sample size, but they also varied in the manner in which statistical analyses were conducted. Scholarly Articles on Animal Experimentation: History, Legislation Only 5/27 studies (19%) described dogs breeds and sources. 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]. 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. Table 3 summarizes psychological outcomes across studies in terms of general psychological health, emotional health, mental health, and self-evaluation.
