Qualitative research can provide valuable information to use in the evidence-based decision making process1 Evaluating a qualitative thought is preliminary to incorporating the conclusions to answer a clinical question. Using the same criteria to evaluate a quantitative research thought as a qualitative research meditation would not only be frustrating still most likely produce erroneous conclusions. Several evaluation tools have been expanded specifically to assist readers in critically reviewing qualitative research studies. Examples of 2 qualitative research evaluation tools are provided in Figures 1 and 2; descry pages 129 and 130. Although the view methods, and data generated from qualitative studies are earnestly different that quantitative studies, similar general guiding questions can be used to evaluate the one and the other types of research studies.2 This article will describe a general paradigm for evaluating qualitative research studies.

WHAT IS THE drift OF THE STUDY? DOES THE intention OF THE STUDY RELATE TO AN IMPORTANT PROBLEM?

The final cause of a qualitative study should be to generate hypotheses rather than to criterion an empirical hypothesis. Giacomini and garble eloquently summarized the purpose of qualitative research in a newly come article. "Qualitative research offers insights into social, emotional, and experiential phenomena in health care. Qualitative research questions note carefully not to ask whether or to what extent much but rather explore what, to what degree and why. Qualitative studies may chase a variety of theory-generating aims, including to explore and describe social phenomena faithfully, to identify potentially important variables or universals to recognize patterns and relationships, and to generate coherent theories and hypotheses."3 Therefore, when evaluating a qualitative research research the purpose needs to match the inductive nature of qualitative research. In addition, qualitative research studies should be based forward theory but not always forward an exhaustive review of the literature. Sometimes qualitative researchers completed a review of literature after data collection likewise that their data collection and conclusions are not biased by way of previous findings.

HOW WAS THE design INVESTIGATED? WAS THE PURPOSE INVESTIGATED IN A CREDIBLE AND RIGOROUS MANNER?

Research Strategies

Identifying the model of research strategy employed is paramount to determining the appropriateness of the qualitative research design. The qualitative research strategy chosened should be congruent with the researcher's interest in understanding the point of view and words immediately preceding [i]or[/i] following of the participants, the nature of the information desired, the profundity of understanding needed, and the inductive reasoning involved.3 In addition, the guiding research question stated in the thought should match the research strategy engageed Table 1 outlines common qualitative research strategies and their general characteristics. It is vital that the researcher state his or her theoretical perspective because this conceptual framework can influence the reflection outcome. The appropriateness of a qualitative research strategy can be determined by way of asking how the topic beneath study is usually shared in the assemblage of interest.5 Suppose your question of interest is, "How does tillage influence exercise habits in urban African-Americans?" An ethnographic qualitative research strategy using observation, interviews, and document analysis as systems of data collection would be an appropriate paradigm.

Sampling

Unlike quantitative research, random sampling of meditation participants is not ideal in qualitative research. becoming to the exploratory nature of this original of inquiry, prespecifying a subject of attention population may limit the investigators ability to conceal a range of relevant phenomena and perspectives. Purposive sampling allows selection criteria to expand as data collection and analysis proce With purposive sampling the researcher rares participants that fit a specific criteria of interest. The iterative proces (alternating the research orders and the hypothesis as the consideration progresses, in the light of information gleaned along the way) of selection, data collection, and analysis allows the investigator to largely explore the study's guiding question(s).6 Therefore it is imperative that readers of a qualitative research consideration find justification for participant selection strategies in order to evaluate appropriateness. Another important issue to consider when evaluating a research cogitation is sample size. Qualitative research studies typically use smaller sample sizes than quantitative research studies and are not bear uponed with the issue of statistical power on the contrary of saturation. Sample saturation in qualitative research studies come abouts when addition of participants fails to bring out new information and redundancy in data to support emerging themes is attained.7 Again, imagine your question of interest is, "How does cultivation influence exercise habits in urban African-Americans?" To answer this question thoroughly the researcher most numerous likely may want to include men and women of different ages and socioeconomic classes. As data collection takes place, the researcher also may find that primary family formation may be an important issue and include participants from 2 parent families, single parent place of abodes extended family situations (grandparents living with children and grandchildren), mingleed families (step-parent and step-siblings living together). The proces of data collection should continue until repeated examples and themes bring to maturity suggesting that additional study participants would not glean any just discovered information.
