Quantitative versus qualitative research: Methodological or ideological dichotomy? Manuscript received by 9. Index de Enfermería [Index Enferm] ; 20 3 : Quantitative versus qualitative research: methodological or ideological dichotomy?. Index de Enfermería [Index Enferm] digital edition ; 20 3. Critical revision of the cause and effect relationship in quantitative research antagonism between qualitative vs. However, in her process of scientific construction, the nursing has chosen to oppose the differential qualitative fundamentalism versus biomedical quantitative orthodoxy.
And although it is logical, it is still disturbing and counterproductive. The facts are quantifiable, but not their signification. And both are two sides of same coin, dimensions of reality to which we can only approach from a proper cause and effect relationship in quantitative research to the facts quantitatively, qualitatively to their significance.
Qualitative vs. Quantitative research: differences who should marry a virgo inferences. The aim of any science is the acquisition of knowledge, so choosing the right method that allows us to know the reality will be fundamental. Inductive methods are generally associated with qualitative research, while deductive method is often associated with quantitative research.
The fundamental difference between scientific method is that one studies the association or relationship between quantified variables and the other do it in structural contexts situacionales. Furthermore, Guba says that "the naturalistic approach aims to develop knowledge idiographic, focusing on cause and effect relationship in quantitative research between objects, as often and with so much cause and effect relationship in quantitative research in the similarities", 4 so that while the rationalists have preferred quantitative methods, the naturalists have preferred to qualitative methods.
According to this author, rationalists believe that the most important criterion for measuring the quality of research is the "rigor" internal validity: "no matter what you do, do it as well"while for the naturalists is the "relevance" external validity, "something not worth doing at all is not simple meaning of primary market research doing well", which despite its romantic aura involves not unrealistic.
In regard to the applicability of the research, the rationalist will search for his external validity in terms of "generalizability" while the naturalist we can make in spanish do in terms of "portability". The most obvious differences between both methods are shown in Table 1developed by Pita and Pértigas 5 based on different authors proposals.
Historical Perspective on Health Sciences. Works published by Conde 9 and Sarrado et al. To Conde, "the historical analysis reveals cause and effect relationship in quantitative research the complex double way of signs and symptoms is equivalent to the complex relationship between qualitative and quantitative perspective". The quantitative approach would be signs and symptoms to the more qualitative relations between the two would be similar to those that occur between these two perspectives in the field of Social Sciences.
For what does him mean ideogram that appears successful, we believe that it could also be a similar parallel, without leaving the qualitative paradigm, from the perspective ETIC as observation of signs and EMIC as an expression of symptoms. In fact, the 'cultural materialism' of Marvin Harris defines these concepts so that Emic is the meaning and sense that things have for the subject, which is not observable since it is on your mind, sculpted by the culture and their own experience.
It is their subjective meaning, while Etic is the meaning and sense to the observer. It is external, what the investigator called explorer alien, the observed fact. Of course, both approaches should be supplemented to discover a total knowledge. The investigator must know Emic and Etic perspectives, and not only in Anthropology. Not until the XIX century to be developed in parallel two dominant perspectives in the field of health: the classic linked to the disease and its cure and the ultimate in hygiene and prevention.
The latter will find in the statistical and epidemiological studies in one of his most important tools in addressing public health. While recognizing the role of statistics, Fleck 12 highlights the uniqueness of the Health Sciences noting how, unlike the natural sciences with the study of the regularities of their screening criteria, the study does not address the regularity but on the contrary, to what is deviant, that is, the disease state.
In the second half of the XX century, a qualitative research methodology reemerged as a front line, mainly in the US and UK. Over the next decade placed to Sarrado et al the emergence of Medical Anthropology now called Anthropology of Health and Disease in various universities of US. These include methods based on Bayes theory, which "are close to know the probability that the events are in a certain way depending on what is observed in reality". As is that in hermeneutic and critical paradigms, cultivated in health sciences mainly by nurses, predominantly methodology "qualitative dialogical and dialectical construction".
It is unacceptable can an as marry an aa the positivist axiom that the phenomena can be reduced to its constituent parts. This means that the whole is equal to the sum of the parties when the human nature itself shows us the opposite day. For Jan Christiann Smuts, South African political philosopher and pioneer of holism, "body, mind, spirit, personal history, values, emotions, culture, aspirations, attitude towards life, temperament, way of relating, society This is a consequence of the holistic concept of care that is based on the nursing profession, a concept first defined in by Smuts "Holism and evolution" and disseminated in our country by figures like Marañón or Laín Entralgo.
To demonstrate this, epidemiologists to Juan Canalejo Hospital of A Coruña Spain objectified in the Medline search using keywords quantitative what causes a spurious correlation versus qualitative researchthe discovery of 11, items and 1, respectively, resulting in a ratio of 8.
When added to cause and effect relationship in quantitative research search word to focus nursing to talk about nursing jobs, objectified that the ratio of qualitative vs. But if further refine your search to pages published only in Spain, this ratio increased to 1. But what happens in the rest of the world? What gives us the most universal form if we perform the search in English? For a really bleak ratio of 9. As pointed out by De la Cuesta Benjumea, "since the cause and effect relationship in quantitative research decades of cause and effect relationship in quantitative research last century qualitative studies have proliferated in the area of health, in particular in Nursing".
So, as we have seen, the majority of nursing research has followed the model of qualitative research because, to our knowledge, the scientific and academic researchers and the pursuit of their own epistemological niche in the field of Sciences Health and a distinctive identity with respect to quantitative biomedical research. In the search for differentiating this identity, the absence of Degree led to an anthropological perspective of care.
However, the holistic approach, the transcultural and qualitative techniques, even though contributions of great value, are not the only way to investigación. In the current framework, with the Nursing Degree and the presentation of Doctoral Thesis made by nurses who are a challenge and an impetus to research in care, the conditions are ideal for the healthcare industry to gain a firm commitment to the research nurse such as pharmaceutical industry bought it long ago with biomedical research.
In words of Mendoza Palacios, "in an investigation client centered theory in social work not appropriate to talk about qualitative paradigm, qualitative or quantitative research methodology", as if we were talking about conflicting ideologies, "as are the qualitative or quantitative research approaches, and both can be used in the same research methodologies interacting".
Final thought: questionable axioms generate complementary methods. In fact, as maintained by epidemiologists everything is quantifiable, even in qualitative research. Something as subjective and subject to the culture and experience that each has the pain is measurable and it is done in clinical practice, using the analog scale of pain when administering analgesia. This is because "things are not meant" as claimed by the followers of symbolic interactionism.
Giving a final twist might wonder how to deal exclusively from the biomedical paradigm phantom limb pain. Then we must admit that, in medicine, "is real what the person defines as real" 34 but it yourself and put it centuries ago the greek philosopher Epictetus, saying that human events affect and are therefore not in itself but the valuation of them do. Therefore, it will be recognized because those charged with the biomedical paradigm critics who claim that "the theoretical affiliation of the author acts as a mask that emerges when he tells his version of events", 35 but without forgetting that this is generalizable to any paradigm, since "qualitative approach to health problems is not just an option As is seen, is a researcher's commitment to the society whose interests are supposed to serve, but that technological progress does not always guarantee".
Put it this way: the facts are quantifiable, but not their meaning. But both, fact and meaning are two sides of the same coin, dimensions of reality to which we can only approach in perspective: facts quantitatively, qualitatively their meanings. Because, to paraphrase Ortega y Gasset, the only wrong perspective is the unique perspective. Table 1. Differences between qualitative and quantitative research 5. Table 2.
