Issues of Reliability and Validity. Things are slightly different, however, in Qualitative research.

In general practice, qualitative research contributes as significantly as quantitative research, in particular regarding psycho-social aspects of patient-care, health services provision, policy setting, and health administrations. In contrast to quantitative research, qualitative research as a whole has been constantly critiqued, if not disparaged, by the lack of consensus for assessing its quality and robustness. This article illustrates with five published studies how qualitative research can impact and reshape the discipline of primary care, spiraling out from clinic-based health screening to community-based disease monitoring, evaluation of out-of-hours triage services to provincial psychiatric care pathways model and finally, national legislation of core measures for children's healthcare insurance.

The purpose of this paper is to shed light on the threats to quality in mixed methods accounting research, wherein quantitative and qualitative approaches are combined in data collection, analysis and interpretation. The paper is framed according to three perspectives. The authors first synthesize the threats to validity and reliability in quantitative and qualitative parts of mixed methods research using the quality standards of each; they then introduce an integrative framework of mixed methods research quality by Teddlie and Tashakkori. The authors' analysis not only indicates a wide range of threats to the validity and reliability of mixed methods research in a range of categories, but also clarifies how the three perspectives described in this paper are linked and supplement each other. Methodological research published in English over the last decade is emphasized to create an approach to assess mixed methods accounting research. The frameworks analyzed could still be studied in greater detail.

Instrument, Validity, Reliability

Reliability is the degree to which an assessment tool produces stable and consistent results. The obtained correlation coefficient would indicate the stability of the scores. Inter-rater reliability is especially useful when judgments can be considered relatively subjective. Thus, the use of this type of reliability would probably be more likely when evaluating artwork as opposed to math problems. Validity refers to how well a test measures what it is purported to measure. Why is it necessary?

Frameworks for ensuring trustworthiness and rigour of qualitative research have been in existence for many years Shenton Validity of Transformative Experiences: An Unfolding: Application of qualitative research in management why, when and how , Understanding and Validity in Qualitative Research.

Validity relates to the appropriateness of any research value, tools and techniques, and processes, including data collection and validation Mohamad et al.

The five conceptions measured were those of repeated trials, evaluating the trustworthiness of data, treatment of anomalous data, internal and external validity of experimental design.

Validity (statistics)

Instrument is the general term that researchers use for a measurement device survey, test, questionnaire, etc. To help distinguish between instrument and instrumentation, consider that the instrument is the device and instrumentation is the course of action the process of developing, testing, and using the device. Instruments fall into two broad categories, researcher-completed and subject-completed, distinguished by those instruments that researchers administer versus those that are completed by participants. Researchers chose which type of instrument, or instruments, to use based on the research question. Examples are listed below:. Example usability problems include:.

Validity is the extent to which a concept , conclusion or measurement is well-founded and likely corresponds accurately to the real world. The validity of a measurement tool for example, a test in education is the degree to which the tool measures what it claims to measure. In psychometrics , validity has a particular application known as test validity : "the degree to which evidence and theory support the interpretations of test scores" "as entailed by proposed uses of tests".
