disadvantages of animal studies in psychology

If small rodents are incapable of feeding, they will die within hours - it is highly likely that many substances would not be toxic if a simple sugar solution was injected. Research on non-human primates, for instance, continues to offer valuable perspectives into the causes and evolution of individual, social, and reproductive human actions. All articles were screened by two independent reviewers (authors KR and JG) using Covidence systematic review software (Veritas Health Innovation, Melbourne, Australia). Can you really generalise results from animals to humans? In the next sub-category, six studies assessed life satisfaction outcomes using Satisfaction with Life Scale [SWLS; 57]. Assistance dog placements and roles have grown rapidly in recent decades, especially in the United States, Canada, and Europe [2]. Advantages and Disadvantages of Animal Testing | Sciencing Animal experimentation, also called animal testing, has contributed to many important scientific and medical discoveries. 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. 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. 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. 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. However, results suggested that for most outcomes, having an assistance dog had no effect on psychosocial health and wellbeing. found better social functioning in those with a mobility or medical service dog compared to a control group [16] while Guest found improved social functioning 3- and 12-months after receiving a hearing dog [13]. In addition, we can better understand fundamental processes because of the precise control enabled by animal research (e.g., living environments, experimental conditions, etc.). 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. However, this research is not only widely disparate but, despite its growth, has not been reviewed since 2012. 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. [16] found that those with a mobility or medical service dog reported significantly higher work/school functioning than a control group. A study protocol was designed a-priori to define the search strategy, inclusion and exclusion criteria, and items for data extraction. alerting or responding to medical crises such hypoglycemia or seizures), and individuals with mental health disorders (e.g. Exclusions included those based on population, outcomes, and methodology. Using the Psychosocial Impact of Assistive Devices Scale [PIADS; 54], Vincent et al. On the other hand, Spence [34] found no improvement to a composite score of psychological health 12-months after receiving a mobility service dog. Animal studies in psychology. 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. Methods matter: A primer on permanent and reversible interference Using the occupation domain of the CHART, Rintala et al. 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. Secondly, many studies did not report sufficient detail in results in terms of estimates of variability and effect size. In methods sections, only 16/27 (59%) of studies indicated whether ethical approval for conducting human subjects research was sought and received. 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. 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. Naturalistic Observation: Definition, Examples, Pros and Cons However, only 1/6 (17%) found a significant effect, in which Yarmolkevich found higher life satisfaction among those with a guide dog compared to a control group. The remaining four longitudinal studies assessed participants 35 times with final follow-up ranging from 924 months after receiving an assistance dog. This pattern suggests a potential publication bias present in which disproportionately more positive findings are in the published studies than the unpublished theses [78]. On the other hand, Donovan [28] found no change in emotional functioning 4-months after receiving mobility service dog. 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. Another potential explanation for inconsistent findings across studies lies in the inherent variability of the assistance dog intervention itself. [16] found higher emotional functioning in those with a mobility or medical service dog compared to a control group. In one example, four studies included in this review failed to find significant results in comparisons of depression using the CES-D [28, 3941]. PDF American Psychological Association (APA) Moderator analyses will be useful in determining the potential explanatory effects that handler-service dog relationships have on psychosocial outcomes. Ten years from now, students may very well read in their textbooks about a new treatment to help people with Parkinsons disease. However, almost all positive findings were accompanied by a null finding using the same or similar standardized measure in a different study. Studies compared outcomes of individuals with an assistance dog to before they received the dog (six longitudinal studies), to participants on the waitlist to receive an assistance dog (five longitudinal and seven cross-sectional studies), or to participants without an assistance dog (eight cross-sectional studies). Ethical and Scientific Considerations Regarding Animal Testing - PLOS Summary of methodological ratings for N = 27 studies ordered by reporting section (. The rationale for excluding qualitative studies from inclusion was to focus on outcomes using standardized measures to facilitate quantitative comparisons across studies. Promising areas include psychological wellbeing, emotional wellbeing, and social participation in which several positive outcomes were identified. To summarize study outcomes, extracted items included statistical comparisons for any psychosocial outcomes from included studies. Assistance Dogs International (ADI) defines three types of assistance dogs, of which we use as terminology in this review: guide dogs who assist individuals with visual impairments, hearing dogs who assist individuals with hearing impairments, and service dogs who assist individuals with disabilities other than blindness or deafness [3]. A main weakness of animal studies is that animals have a different physiology to humans. 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 . Humans share common ancestry with the species most commonly studied in psychology: mice, rats, monkeys. One of the main considerations in understanding the potential variability across findings is the aspect of time since assistance dog placement. 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. Only Vincent et al. Table 4 summarizes the social outcomes across studies within the sub-categories of general social functioning, loneliness, and social participation. Beyond the functional tasks that assistance dogs are trained for, there is growing literature describing their benefits on the psychosocial health and wellbeing of their handlers. 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. 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. Case study advantages and disadvantages. Case Study Advantages and For general psychological health, 5/11 (45%) outcomes were significant across group or condition. We found that similar to the range of study characteristics observed, there was considerable variation in the methodological rigor of included studies. 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]. To achieve the first aim of the reviewto describe study characteristicswe extracted several features of from each study and article (Table 1). The three Rs are a set of principles that scientists are encouraged to follow in order to reduce the impact of research on animals. broad scope, and wide readership a perfect fit for your research every time. Interestingly, only one included study [16] assessed outcomes from participants under the age of 18. Using a new technique, it is now possible to temporarily inactivate the amygdala in a monkey and see how other brain areas (including those that are not directly connected to the amygdala) change their activity (Grayson et al., 2016). In longitudinal studies, the first follow-up time point varied from 3- to 12-months after receiving an assistance dog. Studies assessed the effects of mobility (18), hearing (7), guide (4), and medical (2) assistance dog partnerships with an average sample size of N = 83. MEDLINE search terms and search strategy. 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. The five studies which found that pet owners were less depressed had, on average, many fewer participants (Mean = 401 subjects ) than the studies that found no difference in depression rates (Mean . Other self-evaluation outcomes assessed with null findings included no differences in self-concept between control groups and those with mobility service dogs [37] or guide dogs [46], no differences in attitude towards a disability 4-months after receiving a mobility service dog [28] or among guide dog users compared to a control group [38], and no differences in flourishing among guide dog users compared to a control group [46]. Ironically, those animals that are likely to be the best models for psychopathology are also likely to be considered the . 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. [35] found increased SF-36 health transition scores after 3-months of having a mobility, hearing, or medical service dog, while Guest [13] found an increase in general health 3-months after receiving a hearing dog using the 30-item General Health Questionnaire [GHQ-30; 48]. 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 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. mobility or guide), thus restricting human participants to a single category of impairments. 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. 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]. As Serpell and colleagues point out, individuals that dont benefit from animal-assisted interventions may be just as informative from a scientific perspective as the ones that do, and the entire field potentially suffers when these sorts of contrary or ambiguous findings get buried or ignored [74].
