In recent years qualitative research QR in health sciences has attracted the attention of both those who perform research concerning health care systems and those who work in clinical settings.

Topics that are especially suitable for qualitative methods include quality analysis as well as aspects that are hard to study with quantitative approaches, such as determining the social impact of political decisions, identifying changes needed in professional roles, consensus-building for reaching decisions on policies to be put into practice, analyzing the patient-physician relationship, or identifying issues that matter most to different interest groups.

Quantitative research, on the other hand, is more concerned with determining causal relationships, and with measuring or predicting phenomena as accurately as possible. Qualitative research approaches reality from a wholistic perspective that tries to comprehend or describe it without resorting to hypothesis-formulating or hypothesis-testing, establishing objective measures, controlling carefully for all variables or randomly selecting participants.

It should be noted that the QR focus cannot be considered useful for answering the same why quantitative research is better than qualitative pdf that quantitative research is intended to answer. The aims of qualitatives studies such as those summarized in Table 1 are completely different from those of quantitative studies, although in many cases the two approaches complement each other.

Thus QR techniques are applied in a number of settings where they are particularly useful, and where they are the most appropriate way to gather information, analyze trends and examine our knowledge of a changing reality. Like all research techniques, QR methods are based on assumptions and must be applied why quantitative research is better than qualitative pdf rigor to ensure that the results are valid.

Why quantitative research is better than qualitative pdf particular, two essential features of these techniques deserve emphasis. First, experts are chosen to reflect the different sensibilities, perspectives and points of view of different reference groups. Second, triangulation, i. The main differences between QR and quantitative research can be summarized as follows: Quantitative research is more reductionist in nature and seeks to describe reality in the most objective terms possible, when necessary breaking reality down in order to analyze a part of it in detail.

Qualitative research accepts the possibility that the conclusions may at times be biased. Quantitative research draws on designs that seek by all means possible to avoid any bias or other source of error. In other words, the subjects who are chosen are assumed a priori to have "something to say. The internal validity of quantitative research is dependent mainly on the rigorous control of biases and sources of error, and its external validity depends on the degree of similarity between the subjects and the target population.

Qualitative research is being used increasingly as a source of information 14 or background knowledge for research projects, and is thus used in association with quantitative research techniques. When QR techniques are described, a distinction is often made between eminently descriptive techniques used for information analysis, and the so-called consensus techniques.

Information analysis techniques are mainly descriptive and aim to comprehend or understand reality from different perspectives. Consensus techniques aim to reach agreement on subjects of interest for which conclusive information is unavailable, or when information is hard to obtain and decisions need to be taken or probable courses of action need to be decided. In practice, it is not unusual to find both types of techniques being used together in the same research project.

The aim of this study was to describe the use of qualitative methods in articles published in Spanish health science journals. We quantified the use of qualitative techniques and determined which were used most often. We reviewed research articles based on qualitative research methods and published during the period from April to April Items published in Spanish journals were located by searching the Índice Médico Español IME bibliographic database with the search terms métodos cualitativos and investigación cualitativa.

In addition we perfomed a systematic search for relevant items published in the journals Atención Primaria, Gaceta Sanitaria and Revista de Calidad Asistencialas studies based on qualitative methods usually appear in these serial publications. The inclusion criteria why quantitative research is better than qualitative pdf therefore intended to locate articles published in health science journals indexed in the IME with special emphasis on the serial publications listed above that had been performed entirely with qualitative research methods of any type.

We also included articles that reviewed qualitative research techniques and described the advantages and drawbacks of this type of method in comparison to quantitative methods. The main exclusion criterion was the use of predominantly quantitative research methods even if a qualitative technique had been used for is love really worth it of the study.

The literature review was carried out during the period from September to February In Spain the number of studies done with QR methods has increased steadily as these methods have gained in importance Table 2. Annex 1, why quantitative research is better than qualitative pdf summary of the studies we analyzed, is available on line. The contribution of qualitative research to health sciences has been increasing in terms of the numbers of articles published and the interest shown in the subjects these studies have investigated.

In Spain and elsewhere, QR techniques have undergone a process of rediscovery, 27,28 which has led many health care professionals to express interest in learning about these techniques, their characteristics, and naturally how and when to use them. On the British Medical Journal BMJ published a series of articles which described the logical basis, focus and why quantitative research is better than qualitative pdf of qualitative techniques, and presented the most frequently used techniques.

Five years later, inthe BMJ published another set of articles about these techniques. As found in the present review, this tendency has also appeared in Spain, with the result that the largest number of qualitative studies was published in Some journals such as Atención Primaria devote space specifically to this type of study. We found that qualitative techniques provided added value to research, and that the number of qualitative studies has been increasing. The popularity of these techniques has increased as a result of interest in evaluating and improving the quality of care, the need to obtain more information on patients' opinions and points of view, and undoubtedly new strategies for making health management more participatory.

As in any type of study, qualitative research requires compliance with basic requirements to ensure the validity of its results.
