Research Rundowns >Quantitative Methods > Instrumentation, Validity, Reliability Part I: The Instrument Instrument is the generic term that researchers use for a measurement device (survey, test, questionnaire, etc.). Several researchers argued that reliability and validity pertain to quantitative research, which is unrelated or not pertinent to qualitative inquiry because it is aligned with the positivist view.

Reliability and validity are concepts used to evaluate the quality of research. Understanding Validity in Qualitative Research. deal of attention is applied to reliability and validity in all research methods. What are validity and reliability in qualitative research? Reliability in quantitative research stems from statistical results that have consistency (Roberts & Priest, 2006). Content validity, derived during concept elicitation, is the measurement property that assesses whether items are comprehensive and adequately reflect the patient perspective for the population of interest. And, in general, checking for validity of an instrument is more difficult than checking for reliability because validity is measuring data related to knowledge whereas reliability only concerns with the consistency of scores. Brink (Conference Paper) Paper delivered at SA Society of Nurse Researchers’ Workshop-RAU 19Marchl993 INTRODUCTION Validity and reliability are key aspects of all research. Sometimes, especially in qualitative research it is only the participants of the research who can legitimately judge the credibility of results. Establishing validity and reliability in qualitative research can be less precise, though participant/member checks, peer evaluation (another researcher checks the researcher’s inferences based on the instrument (Denzin & Lincoln, 2005), and multiple methods (keyword: triangulation), are convincingly used. In particular sample size and validity are the most often queried aspects of qualitative research. View Validity, reliability, and generalizability in qualitative research.pdf from BUS 260 at Metropolitan Community College, Business & Technology. (2003) and Parkes et al. Challenges to rigor in qualitative inquiry interestingly paralleled the blossoming of statistical packages and the development of computing systems in quantitative research. When asked about the biggest challenges faced in quantitative research , 37% of UX practitioners interviewed by the Norman Nielsen Group claimed that recruiting large samples of participants was the most difficult task of all. Measures to ensure validity of a research include, but not limited to the following points: a) Appropriate time scale for the study has to be selected; b) Appropriate methodology has to be chosen, taking into account the characteristics of the study; In other words, however many times you measure something the results should always be the same. endstream endobj startxref Reliability and validity are also not fixed qualities, they may change over time. Keywords: General Social Survey, Sampling Design, Reliability and Validity I. It further discusses various forms of validity and reliability tests with concise examples and finally explains various methods of analysing these tests with scientific principles guiding such analysis. Ensuring Validity. But steps must be taken to help ensure as far as possible that the work’s findings are the result of experiences and ideas of the informants, and that evaluation findings are arrived at by considering solid evidence. Rooted in the positivist approach of philosophy, quantitative research deals primarily with the culmination of empirical conceptions (Winter 2000). Attention to these considerations helps to insure the quality of your measurement and of the data collected for your study. Reliability in research.

The validity of the research findings are influenced by a range of different factors including choice of sample, researcher bias and design of the research tools. Though it is difficult to maintain validity in qualitative research but there are some alternate ways in which the quality of the qualitative research can be enhanced. The concept of reliability, generalizability, and validity in qualitative research is often criticized by the proponents of quantitative research. The best research projects actually use a combination of the two methods of data gathering. You can download the paper by clicking the button above.

These two concepts are validity and reliability. It explores the basis and use of quantitative research and the nature of scientific rigour. The extent to which qualitative findings can be confirmed is challenging, as it is difficult ensuring objectivity to qualitative research. Depending on their philosophical perspectives, some qualitative researchers reject the framework of validity that is commonly accepted in more quantitative research in the social sciences. The concept of reliability is then analysed, establishing the traditional understanding of the term, and evaluating alternative terms. Dealing with different types of validity is what makes establishing validity in qualitative research very difficult. Quantitative research is usually done on a large scale and for good reason, or you run the risk of getting narrow results that damage the overall validity of your study. Validity is defined as the extent to which a concept is accurately measured in a quantitative study. Steps in validating a questionnaire include; Establish face validity. Qualitative research investigates events that are difficult to quantify mathematically, such as beliefs. Validity and reliability are two important factors to consider when developing and testing any instrument (e.g., content assessment test, questionnaire) for use in a study. Recognize the importance of combining qualitative and quantitative research to get the best result. Whether the same measurement process yields the same results.
