Qualitative research is a field of inquiry that crosscuts disciplines and subject matters [1]. Qualitative researchers aim to gather an in-depth understanding of human behavior and the reasons that govern such behavior. The discipline investigates the why and how of decision making, not just what, where, when. Hence, smaller but focused samples are more often needed rather than large random samples.

[edit] History
Qualitative research was one of the first forms of social studies (conducted e.g. by Bronisław Malinowski or Elton Mayo), but in the 1950s and 1960s - as quantitative science reached its peak of popularity (The Quantitative Revolution)- it was diminished in importance and began to regain recognition only in the 1970s. The phrase 'qualitative research' was until then restricted as a discipline of anthropology or sociology, and terms like ethnography, fieldwork, participant observation and Chicago school (sociology) were used instead. During the 1970s and 1980s qualitative research began to be used in other disciplines, and became a significant type of research in the fields of education studies, social work studies, women's studies, disability studies, information studies, management studies, nursing service studies, human service studies, psychology, communication studies, and other. Some qualitative research occurred in the consumer products industry during this period: researchers most interested in investigating consumer new product and product positioning opportunities worked with a handful of the earliest consumer research pioneers including Gene Reilly of The Gene Reilly Group in Darien, CT, Jerry Schoenfeld of Gerald Schoenfeld & Partners in Tarrytown, NY and Martin Calle of Calle & Company, Greenwich, CT. In the late 1980s and 1990s after a spate of criticisms from the quantitative side, paralleling a slowdown in traditional media spending for the decade, new methods of qualitative research evolved, to address the perceived problems with reliability and imprecise modes of data analysis.[2]
In the last thirty years the acceptance of qualitative research by journal publishers and editors has been growing. Prior to that time many mainstream journals were prone to publish research articles based upon the natural sciences and which featured quantitative analysis [3].
[edit] Distinctions from quantitative research
The term qualitative research is most often used in the social sciences in contrast to quantitative research. It differs from quantitative research in many ways and often (though not always) rests on different philosophies of science or knowledge. These differences have been the source of considerable divisiveness and misunderstanding in the social sciences and often parallels the divisions between so-called continental philosophies and analytical philosophies. However, in more recent times approaches to social science research that use a variety of both quantitative and qualitative methods - often called mixed methods research - has become increasingly accepted and common. It has been argued that rather than one approach being definitively more conclusive or 'true' than the other, they are better understood as different discursive practices.
In a practical sense there are some key differences between qualitative and quantitative research. Firstly, in qualitative studies sampling sizes are usually smaller and typically not random but purposive in design. In other words, cases can be selected according to whether they typify, or not, certain characteristics or contextual locations. Secondly, the role or position of the researcher is given greater critical attention. This is because in qualitative research the possibility of the researcher taking a 'neutral' or transcendental position is seen as more problematic in practical and/or philosophical terms. Hence qualitative researchers are often exhorted to reflect on their role in the research process and make this clear in the analysis. Thirdly, while qualitative data analysis can take a wide variety of forms it tends to differ from quantitative research in the focus on language, signs and meaning as well as approaches to analysis that are holistic and contextual, rather than reductionist and isolationist. Nevertheless, systematic and transparent approaches to analysis are almost always regarded as essential for rigor. For example, many qualitative methods require researchers to carefully code data and discern and document themes in a consistent and reliable way.
Perhaps the most traditional division in the way qualitative and quantitative research have been used in the social sciences is for qualitative methods to be used for exploratory (i.e., hypothesis-generating) purposes or explaining puzzling quantitative results, while quantitative methods are used to test hypotheses. This is because establishing content validity - do measures measure what a researcher thinks they measure? - is seen as one of the strengths of qualitative research. While quantitative methods are seen as providing more representative, reliable and precise measures through focused hypotheses, measurement tools and applied mathematics. By contrast, qualitative data is usually difficult to graph or display in mathematical terms.
Qualitative research is often used for policy and program evaluation research since it can answer certain important questions more efficiently and effectively than quantitative approaches. This is particularly the case for understanding how and why certain outcomes were achieved (not just what was achieved) but also answering important questions about relevance, unintended effects and impact of programs such as: Were expectations reasonable? Did processes operate as expected? Were key players able to carry out their duties? Were there any unintended effects of the program? Qualitative approaches have the advantage of allowing for more diversity in responses as well as the capacity to adapt to new developments or issues during the research process itself. While qualitative research can be expensive and time-consuming to conduct, many fields of research employ qualitative techniques that have been specifically developed to provide more succinct, cost-efficient and timely results. Rapid Rural Appraisal is one formalised example of these adaptations but there are many others.
[edit] Data Collection
Qualitative researchers may use different approaches in collecting data, such as the grounded theory practice, narratology, storytelling, classical ethnography, or shadowing. Qualitative methods are also loosely present in other methodological approaches, such as action research or actor-network theory. Forms of the data collected can include interviews and group discussions, observation and reflection field notes, various texts, pictures, and other materials.
Qualitative research often categorizes data into patterns as the primary basis for organizing and reporting results.[citation needed] Qualitative researchers typically rely on the following methods for gathering information: Participant Observation, Non-participant Observation, Field Notes, Reflexive Journals, Structured Interview, Unstructured Interview, Analysis of documents and materials [4].
The ways of participating and observing can vary widely from setting to setting. Participant observation is a strategy of reflexive learning, not a single method of observing[5]. In participant observation [1] researchers typically become members of a culture, group, or setting, and adopt roles to conform to that setting. In doing so, the aim is for the researcher to gain a closer insight into the culture's practices, motivations and emotions. It is argued that the researchers' ability to understand the experiences of the culture may be inhibited if they observe without participating.
Some distinctive qualitative methods are the use of focus groups and key informant interviews. The focus group technique involves a moderator facilitating a small group discussion between selected individuals on a particular topic. This is a particularly popular method in market research and testing new initiatives with users/workers.
One traditional and specialized form of qualitative research is called cognitive testing or pilot testing which is used in the development of quantitative survey items. Survey items are piloted on study participants to test the reliability and validity of the items.
In the academic social sciences the most frequently used qualitative research approaches include:
1. Ethnographic Research, used for investigating cultures by collecting and describing data that is intended to help in the development of a theory. This method is also called “ethnomethodology” or "methodology of the people". An example of applied ethnographic research, is the study of a particular culture and their understanding of the role of a particular disease in their cultural framework.
2. Critical Social Research, used by a researcher to understand how people communicate and develop symbolic meanings.
3. Ethical Inquiry, an intellectual analysis of ethical problems. It includes the study of ethics as related to obligation, rights, duty, right and wrong, choice etc.
4. Foundational Research, examines the foundations for a science, analyses the beliefs and develops ways to specify how a knowledge base should change in light of new information.
5. Historical Research, allows one to discuss past and present events in the context of the present condition, and allows one to reflect and provide possible answers to current issues and problems. Historical research helps us in answering questions such as: Where have we come from, where are we, who are we now and where are we going?
6. Grounded Theory, is an inductive type of research, based or “grounded” in the observations or data from which it was developed; it uses a variety of data sources, including quantitative data, review of records, interviews, observation and surveys.
7. Phenomenological Research, describes the “subjective reality” of an event, as perceived by the study population; it is the study of a phenomenon.
8. Philosophical Research, is conducted by field experts within the boundaries of a specific field of study or profession, the best qualified individual in any field of study to use an intellectual analyses, in order to clarify definitions, identify ethics, or make a value judgment concerning an issue in their field of study.
[edit] Data Analysis
The most common analysis of qualitative data is observer impression. That is, expert or layman observers examine the data, form an impression and report their impression in a structured and sometimes quantitative form. These impressions can be the final conclusion of the analysis, or some quantitative characteristics of the data to be further analyzed using quantitative methods. An example of quantitative techniques is the documenting of word frequencies in textual data, sometimes called content analysis.
Contemporary qualitative studies are sometimes supported by computer programs. The benefits of these types of programs are mostly limited to storing and segregating data, rather than in processing or analyzing them.
[edit] Paradigmatic Differences
Contemporary qualitative research has been conducted from a large number of various paradigms that influence conceptual and metatheoretical concerns of legitimacy, control, data analysis, ontology, and epistemology, among others. Research conducted in the last 10 years has been characterized by a distinct turn toward more interpretive, postmodern, and critical practices[6]. Guba and Lincoln (2005) identify five main paradigms of contemporary qualitative research: positivism, postpositivism, critical theories, constructivism, and participatory/cooperative paradigms[7]. Each of the paradigms listed by Guba and Lincoln are characterized by axiomatic differences in axiology, intended action of research, control of research process/outcomes, relationship to foundations of truth and knowledge, validity (see below), textual representation and voice of the researcher/participants, and commensurability with other paradigms. In particular, commensurability involves the extent to which paradigmatic concerns “can be retrofitted to each other in ways that make the simultaneous practice of both possible”[8]. Positivist and postpositivist paradigms share commensurable assumptions but are largely incommensurable with critical, constructivist, and participatory paradigms. Likewise, critical, constructivist, and participatory paradigms are commensurable on certain issues (e.g., intended action and textual representation).
[edit] Validation
One of the central issues in qualitative research is validity (also known as credibility and/or dependability). There are many different ways of establishing validity, including: member check, interviewer corroboration, peer debriefing, prolonged engagement, negative case analysis, auditability, confirmability, bracketing, and balance. Most of these methods were coined, or at least extensively described by Lincoln and Guba (1985)[9]
Validation, however, is inherently based on a philosophy of positivism. Non positivistic viewpoints include the idea that findings do not need to be reproducible, verifiable, or consistent, and idea that comes from the notion that there are multiple realities, not just one. For positivistic viewpoints, though, validation is as important as the research itself.
[edit] Academic Research
By the end of the 1970’s many leading journals began to publish qualitative research articles [10] and several new journals emerged which published only qualitative research studies and articles about qualitative research methods [11].
In the 1980’s and 1990’s, the new qualitative research journals became more multidisciplinary in focus moving beyond qualitative research’s traditional disciplinary roots of anthropology, sociology, and philosophy [12].
The new millennium saw a dramatic increase in the number of journals specializing in qualitative research publications with at least one new qualitative research journal being launched each year.
