Abstract The eternal discussion of which method to use when initiating an investigation has not come quanfitative an end, since hard or exact sciences expose that scientific rigor must take a series of sequenced steps to accepting or not accepting a hypothesis, the philosophical sciences favor the use of tools and techniques based on ethnography to try to understand the phenomenon and the object of the investigation, because of quxntitative, this essay aims to help young researchers to be more clear in selecting their method of evaluation in one qualitstive, without being exclusive one method of the other, but rather complementary.

However, a weakness is that it can generate bettet systematic data, whose classification and analysis will be difficult and slow. Second, triangulation, i. Are the results of the study valid? On the other hand, participant observation is useful as social phenomena and life cycles are investigated, anthropologists have in this technique a valuable tool. From there one can resort why qualitative research is better than quantitative pdf the measurement of certain variables through the determination of the indicators.

Correspondencia : Prof. Department of Family and Commnunity Health. University of Maryland. Baltimore, Maryland Estados Unidos. Correo electrónico: cmunt umaryland. Recibido : 20 de octubre de Aceptado : 23 de abril de The increasing popularity of qualitative methods in public health has been accompanied by philosophical epistemological, ontological and ethical controversies regarding their use, in iis in epidemiology 1. In this article we review some of these debates, give a typology of the use of qualitative research and suggest a new understanding of why qualitative research is better than quantitative pdf uses of qualitative research in social epidemiology with two illustrations.

We rssearch that in the history of public health and associated population health disciplines, qualitative research has often played the role of «whistle blower». Thus, qualitative researchers have been able to point to social mechanisms affecting health e. Thus, by pointing to mechanisms that had been previously marginalized or ignored, qualitative research has had a positive heuristic why qualitative research is better than quantitative pdf epidemiology and public health.

One of the most common critiques launched against qualitative research is that it focuses on detailed descriptions of interpersonal interactions, without relating them to social structure, as in Ervin Goffman's social psychology of everyday interactions 2. That is, qualitative research suffers from ontological individualism.

However, in current public health most qualitative studies try to link naturalistic observations with broader social structures. For example, Erenreich's study 3 of the work experience of low wage service sector women in the United States e. Similarly, the ethnographic studies by Kim et al qualitative studies of globalization and health 4 connect the poor health of the Haitian and Latin American poor to the policies of the World Bank and the International Monetary Fund.

On the other hand most social epidemiology up to the mid to late nineties ignored the social context by focusing exclusively on individual attributes e. Qualitative research has also been attacked by its epistemological idealism i. Most traditions in anthropology from which qualitative research has emerged spouse ix ethnomethodology, symbolic interactionism. Nonetheless in social epidemiology, even when qualitative researchers claim to adhere to such philosophies, in practice they collect data and provide explanations like a realist would do.

For example, although Amy Schultz's qualitative research 6 declares allegiance to subjectivism, her detailed account of Why qualitative research is better than quantitative pdf American women in Detroit points to the structural inequalities lack of investment, residential researvh, unemployment, decaying city infrastructure that impact the health of African American women.

Conversely some of the most popular hypotheses in social epidemiology have idealist underpinnings. For example Wilkinson's perceptions of income inequality 7 and social capital 8 hypotheses share the assumption that perceptions, rather than objective reality are major determinants of a person's health. A third critique of qualitative research states that the personal involvement of researchers with their populations and the blurring of the researcher-researched distinction easily become unethical.

Examples of these problems are the participation of illegal activities e. For example Loic Waquant 9 has recently provided a detailed critique of the value judgments present in some of most popular urban ethnographies in the United States, where qualitative research artificially divide African American communities into «good law abiding» and «bad delinquent» types. On the other hand some contemporary methods of data collection in social epidemiology, such as the videotaping of neighborhoods in search of «broken windows», why qualitative research is better than quantitative pdf, drug elden ring explained lore sex trade 8 could also be characterized as unethical as they violate the right to intimacy of poor community residents wealthy neighborhoods are not subjected to such type of inquiries.

Thus we find that while the common criticisms i. In addition, quantitative research often suffers from similar what is the relationship of husband and wife. In the next section we outline a classification of uses of qualitative research in social epidemiology. The current view of qualitative research is that it constitutes a complement to quantitative research The limitations of surveys are widely acknowledged.

For example certain populations are more easily accessed with qualitative research than with survey methods e. The skepticism surrounding the validity of the large and expensive quantitative NORC study on the sexual behavior of US populations where elderly men reported high levels of sexual behavior, among other improbable findings, indicated that wuantitative and why qualitative research is better than quantitative pdf analysis could not overcome basic issues of response validity.

Even statisticians such as Adrian Rafftery have noted the necessity of developing qualitative methods. Thus qualitative research is used in the following situations: a when there is lack of background eesearch e. These can be nested e. We believe that qualitative research is suantitative used in social thna as a tool to generate hypotheses or to find social mechanisms racial segregation, deprivation that are not addressed in quantitative studies.

Such use of qualitative research is not identical to «action research», common in applied disciplines, where social change and qualitative research go hand-in-hand. The use that we are referring to is restricted to the academic world and no claims of larger social influence are attempted. For example, Elliott Liebow, one of the top best sellers of post World War sociology in the United States with his ethnography of Black unemployment in s' Washington opened the door to acknowledging that the poverty and lifestyle of unemployed Black men in the United States was due to hwy of opportunity rather than to character flaws such as laziness.

It is worth pointing out that when «Tally's Corner» was published there had already been decades of racial and health statistics although quantitative research on segregation or racism why qualitative research is better than quantitative pdf practically absent. In the what is the relationship between regression and correlation coefficients section we illustrate such use of qualitative research as a hypothesis generating tool in social epidemiology with an example from our own research.

Qualitative research as a hypothesis generating tool and controversies in social epidemiology. The use of qualitative information often suggests different explanations than those conveyed through quantitative surveys. We provide an example on the different implications generated from qualitative and quantitative research using research on the mental health of a community in Baltimore, Maryland. Quantitative studies using surveys by Muntaner et al 11 provided data on prevalence of anxiety disorders in this community in the mid s.

Prevalence of anxiety disorders was associated thqn poverty and educational levels showing increased anxiety disorders in families with greater poverty and lower educational attainment. However, the survey method did not provide an explanation for this association. Qualitative studies using key informants and focus groups on this same population, also conducted in the s, revealed mental health problems as well as a detailed account of the social mechanisms that residents believed were causing their ill health table 1 The qualitative studies showed how lack of political clout and community control of housing redevelopment resulted in anxiety and poor health indicators.

Examples of responses from key informant interviews included «I'm wound up a bit and could relax more Thus, the quantitative study by Muntaner et al 11 shy objective results of anxiety prevalence by social class but could not identify what mechanism might be leading to these levels of anxiety. The qualitative study showed how the lack of strong political influence and inadequate political bonds with the local government and the powerful developer lead to a quqlitative feeling powerless in controlling its future table 2.

Minimal inferences by the authors were included in the report of how redevelopment in this community resulted in poor health outcomes. Instead, the community told the interviewer exactly what they thought was making what is an easy bible to read and understand feel stressed and anxiety ridden pointing to a new set of testable empirical hypotheses table 1 e.

Current quantitative and qualitative studies of the process of redevelopment in why qualitative research is better than quantitative pdf East Baltimore community additionally show the quantitatuve of qualitative or mixed methods research. During probing by the interviewer following this response, these same respondents told anecdotes of unfair treatment of themselves and neighbors in the redevelopment process.

Examples include «They decided to tear our houses down, then they told us about it; didn't even ask quantitayive and «they're not letting us move where we want to, trying to keep all the black people living together»; «after the people with money moved out, the city didn't care about us anymore; just left us to deteriorate». These examples highlight how residents really feel about the entire redevelopment process and the political mechanisms they feel are involved in determining the process of redevelopment.

Similarly, the mechanisms that lead to the deterioration are not seen unless probing types of causation in philosophy allowed. Using only quantitative survey data often does not allow this type of insight and allows these mechanisms to go unreported and addressed. Qualitative research allows inquiry into mechanisms not easily accessed by surveys and supports researchers in further addressing a more political analysis of urban renewal and its health effects see tables.

These examples from betteg own research point to the limited ability of survey instruments in uncovering social determinants of neighborhood health. Whether such limitation is an intrinsic shortcoming of quantitative survey methods or whether it just reflects researchers' theoretical biases is open to debate. Going back to our example, it is likely that the process of forced urban relocation and its health effects could be measured quantitatively. Thus, urban sociologists have developed ahy methods to assess processes such as segregation and gentrification using administrative data and primary data collection.

In that case the superficiality of quantitative surveys in uncovering social determinants of health could be at least partially solved if survey qualitatuve dared to measure controversial but realistic social resdarch such as racial and class segregation zoning, redlining, banking on neighborhoods, neighborhood covenants or political relations between institutions that may determine traumatic urban redevelopment for residents. It is also recognized that qualitative research may intentionally omit a more political perspective by ignoring the types of questions that would elicit these political responses.

This phenomenon of qualitative research is due to the subjectivity of this methodology. For example, in Duneiers' «Sidewalk» 14he reports on street vendors as «more complicated than the stereotype might indicate». They take pride in making an honest living. They compete for prime sidewalk space. They delegate tasks like true business managers. And only a few of them are alcoholics or drug abusers». Lacking in this qualitative study is a political analysis of why these individuals live this «street life» or the racial or class analysis of their lives.

The author set out to write a book to convince the readers that street vendors are «no different» from the rest of us why qualitative research is better than quantitative pdf providing an analysis of why certain groups of people are more likely to adopt this «lifestyle». In the qualitative research publication by Klinenberg, the exact opposite is intentionally conveyed.

This study intricately highlights the political effects of poverty and race by describing how a large percentage of the individuals killed in one week in the Chicago heat wave during the summer of lived alone and had no family or community supervision. Kunenberg's qualitative study discusses the racial and economic betetr of the disaster and comments on the skeptical response of city officials and the media, during and after the event These two examples of qualitative data gathering clearly show how the views of the researcher dramatically shape the outcome of the study.

Thus, when possible, one should go beyond qualitative methods and provide objective and quantitative tests of the ensuing hypotheses. The likelihood of funding for qualitative research, where a class 1 driving test cost critical perspective what type of change is evolution be presented, also remains a potential obstacle to the growth of qualitative research.

Currently, quantitative research follows a more formalized structure that demands greater funding mechanisms. Though funding for qualitative research may require lower costs in part due to the «informal, non-expert» perception, it is exactly this perception that results in the decreased likelihood of funding opportunities. Ironically, it is this «marginal» aspect of funding that leads to qualitative research historically being at the forefront of new research agendas.

For example, as shown above qualitative reports of health disparities in the United States have existed for many years. However, only recently have funding agencies initiated large-scale requests for proposals to more thoroughly understand quabtitative reasons for these health disparities across different types of populations. The promise of qualitative research in social examples of evolutionary model in software engineering is likely to stem from the integration of methods that increase the reliability and objectivity of qualitative methods while simultaneously increasing the validity of survey research for a given population health problem.

In other words there is no shortcut to scientific standards. Nevertheless because public health research is quantittative influenced by political considerations, qualitative research can play an important role to point to social mechanisms and hypotheses that are ignored in mainstream quantitative research, and even in some circumstances that may not be easily approached with quantitative methods.
