An important finding from this review was that most positive findings were reported in published studies, while unpublished theses were more likely to report null findings. Other null findings included no effect of having a guide dog on social conflict stress and interactions with others [42], no improvement in social relationships 12-months after receiving a mobility service dog, and null findings regarding self-reported friendship and companionship with a mobility or medical service dog [16] or 4-months after receiving a mobility service dog [28]. Measures of the same outcome not only can have different wording and items, but also can measure functioning over different time periods or contexts. Studies made an average of 5.4 statistical comparisons on psychosocial outcomes, ranging from 115 comparisons. Marguerite E. OHaire, Affiliation: Tissue cultures cannot develop depression, alco- holism, autism, learning disorders, memory impairments, aggressive behavior, social abnormalities, or other psychologically relevant prob- lems. This occurred by either matching groups on select criteria or statistically comparing groups demographic characteristics before performing main analyses. In addition to poor methodological reporting, many studies were restrained by statistical weaknesses. 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. They have advantages and disadvantages compared with other approaches. In the case of disagreements, inclusion or exclusion was resolved by discussion and consultation with a third independent reviewer (author MO). mobility or guide), thus restricting human participants to a single category of impairments. 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. Summary of methodological rating scores by each of the N = 27 individual studies. Most studies (24/27; 89%) assessed outcomes from a single type of assistance dog (e.g. https://assistancedogsinternational.org/resources/adi-terms-definitions/, https://doi.org/10.1016/S0168-1591(98)00120-8, https://www.nhlbi.nih.gov/health-topics/study-quality-assessment-tools, https://www.cardiff.ac.uk/specialist-unit-for-review-evidence/resources/critical-appraisal-checklists, Corrections, Expressions of Concern, and Retractions. On the other hand, Donovan [28] found no change in emotional functioning 4-months after receiving mobility service dog. In other contexts, dogs can be specially trained to provide specific benefits to individuals with impairments, disabilities, or chronic conditions as trained assistance animals. 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. Register for the early bird rate. 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. Therefore, future efforts should be made to publish null findings in peer-reviewed journals and to encourage scientific transparency [80]. Of five studies using a version of the UCLA Loneliness Scale [55] only Yarmolkevich [46] found significantly lower self-reported loneliness in those with a guide dog compared to a control group. S2 Table. However, inclusion and exclusion criteria were less commonly described (17/27; 63%). The rhesus monkey connectome predicts disrupted functional networks resulting from pharmacogenetic inactivation of the amygdala. 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. Longitudinal assessment time points were varied. To date, there have been several reviews summarizing the literature on the psychosocial effects of assistance dogs on their handlers. 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]. In addition, the scientist must justify the numbers of animals that they use, insuring they are using the smallest number possible. The final sample included 24 articles (12 peer-reviewed publications, 12 unpublished theses/dissertations) containing 27 individual studies. 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. Only 6/27 (22%) reported any estimates of effect size in their results. For the study of most cognitive functions, lesion studies in animals have and will likely continue to provide insights that cannot be obtained through research on humans. Promising areas include psychological wellbeing, emotional wellbeing, and social participation in which several positive outcomes were identified. 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. The below discussion considers various potential explanations for the inconsistencies in findings across studies. 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. 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 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. Studies on psychiatric service dogs, emotional support dogs, and pet dogs were excluded. Answer and Explanation: A study protocol was designed a-priori to define the search strategy, inclusion and exclusion criteria, and items for data extraction. 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. Of the 44 positive comparisons, 36 (82%) were from published papers and 8 (18%) were from unpublished theses. Service dogs can assist individuals with physical disabilities (e.g. Using a different measure of emotional functioning, Rodriguez et al. 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. Of 27 studies, 18 (67%) reported outcomes a standardized measure of social health with a total of 18 different standardized measures. In terms of general vitality and energy, four studies used the SF-36 to measure the effect of having an assistance dog on the vitality domain. Pet-Owning Kids Are Generally Better Off This practice was instrumental in our evolution and in the emergence of civilization. [15] found no difference in self-esteem, adequacy, or competency over 12-months following receiving a mobility service dog. While there are no legal requirements specifying that an assistance dog must be certified, registered, or receive any specialized training to receive public access rights, independent organizations such as ADI, the International Association of Assistance Dog Partners (IAADP), and the International Guide Dog Federation (IGDF) define a set of minimum training and behavior standards for public access that help guide the assistance dog industry. Conducting periodic systematic reviews of this research is crucial to both disseminate knowledge as well as to identify knowledge gaps for future studies [20]. Many studies did not confirm that participants across groups were statistically equivalent on key demographic variables such as age and sex/gender before conducting statistical analyses. To examine the relationship between methodological rigor score and year of publication as well as sample size, bivariate correlations were performed. In these studies, positive findings (i.e., better social functioning in those with an assistance dog compared to a control group) may be partially attributed to an unmeasured variable driving the group difference [77]. 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. Advantages And Disadvantages Of Case Studies Psychology Essay. 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. 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. Using the Profile of Mood States Scale [POMS; 51], Guest found increased self-reported vigor 3- and 12-months after receiving a hearing dog and less fatigue 3-months after receiving a hearing dog. Finally, Rodriguez et al. Capitanio, J. Advancing psychology to benefit society and improve lives. 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. Oversight and inspection of facilities is provided by the U.S. Dept. 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 Medical service dogs for diabetes and seizure alert/response were rarely studied [16, 35], and were assessed in conjunction with mobility service dogs rather than on their own. Seven studies (26%) had sample sizes less than or equal to N = 20, all of which were longitudinal. Despite the purpose of these assistance dogs specifically for physical tasks, positive outcomes were noted in psychological, social, quality of life, and vitality domains. 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). Four studies found no effect of having a hearing dog [29] or mobility service dog [39, 41] on the UCLA Loneliness Scale. But, was then later tested on a human and the human died. To assess methodological rigor, a total of 15 extracted items were sourced from methodological assessment tools including the National Institutes of Health (NIH) Study Quality Assessment Tools [24], the Consolidated Standards of Reporting Trials (CONSORT) checklist [25], the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklists [26], and the Specialist Unit for Review Evidence (SURE) Checklists [27]. Ethical Considerations and Advances in the Understanding of Animal Cognition. Grayson D.S., Bliss-Moreau E., Machado C.J., Bennett J., Shen K., Grant K.A., Fair D.A., Amaral, D.G. The remaining studies were quasi-experimental in that they did not use randomized assignment to treatment or control groups. Only 5/27 studies (19%) described dogs breeds and sources. 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]. Assistance dog categories (guide, hearing, mobility, and medical) were collapsed for the purposes of this review, but undoubtedly contribute to the lives of individuals with disabilities in diverse ways. Moderator analyses will be useful in determining the potential explanatory effects that handler-service dog relationships have on psychosocial outcomes. 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. 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). Vassar College, Poughkeepsie, New York, United States of America, Affiliation: However, almost all positive findings were accompanied by a null finding using the same or similar standardized measure in a different study. The disadvantage of animal research is that it lessens the value of life. Animal Domestication: Animal domestication is when humans take animals from the wild and keep them over successive generations in controlled environments where the animals are always available to humans. [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. Finally, its important to note that animal research in the United States is very tightly regulated by a series of federal and state laws, policies and regulations, dating back to the landmark Animal Welfare Act from 1966. Guide dogs were only assessed in four studies (all of which were cross-sectional, and one of which was an unpublished thesis [46]). The only other positive outcome was from Allen et al. Can you really generalise results from animals to humans? In this review, we have provided a primer on permanent and reversible lesion techniques currently in use in animal research, and a brief discussion of how they might . Yarmolkevich [46] found a significant effect of having a guide dog on positive affect using the Scale of Positive and Negative Experience [SPANE; 49] compared to a control group, while others studies found no effect of having a hearing dog [29] or mobility service dog [39] on affect via the Positive and Negative Affect Scale [PANAS; 50]. [15] found a significant increase in pep, energy, and feeling less worn out 3- and 6-months after receiving a mobility service dog while three studies found no relationship between the vitality domain and having a mobility service dog [17, 28] or a mobility, hearing, or medical service dog [35].
