The concept of reliability, generalizability, and validity in qualitative research is often criticized by the proponents of quantitative research. Threats to internal validity in quantitative research compromise our confidence in stating that a relationship exists between the independent and dependent variables. Validity and reliability are two important aspects in order to approve and validate the quantitative research. In essence, it is how well a test or piece of research measures what it is intended to measure.

A test, for example, is valid if it can measure what it is designed to measure. Validity should be considered in the very earliest stages of your research, when you decide how you will collect your data. Issues are still raised even now in the 21st century by the persistent concern with achieving rigor in qualitative research.There is also a continuing debate about the analogous terms reliability and validity in naturalistic inquiries as opposed to quantitative investigations. If there is low validity in a study, it usually means that the research design is flawed and the results will be of little or no value. For example, a survey designed to explore depression but which actually measures anxiety would not be considered valid. Validity is defined as the extent to which a concept is accurately measured in a quantitative study. Issues of research reliability and validity need to be addressed in methodology chapter in a concise manner.

Occasionally, there will be no mention of hypotheses, but anytime there are inferential statistics used, the reader can recognize what the hypotheses are from looking at the results of statistical analysis. However, validity is better evidenced in quantitative studies than in qualitative research studies. Four different aspects of validity should be considered when reviewing a research design: statistical conclusion validity, internal validity, construct validity, and external validity. High reliability is one indicator that a measurement is valid. Measurement may be defined as the process of assigning numbers to the properties or attributes of client variables. Demystifying the research process: Understanding a descriptive comparative research design. Together, validity and reliability serve as the foundation for sound scientific inquiry. Is there an integrated summary of the current knowledge base regarding the research problem, or does the literature review contain opinion or anecdotal articles without any synthesis or summary of the whole? Traditionally, the establishment of instrument validity was limited to the sphere of quantitative research. 8. Instruments and Strategies for Measurement. Readings. If a method measures what it claims to measure, and the results closely correspond to real-world values, then it can be considered valid.

Multiple strategies can be used to ensure validity in qualitative research, such as triangulation, member checking, rich description, prolonged time in the field, and use of external auditors (Creswell, 2014; Creswell & Poth, 2018). Similarly, the procedures of establishing validity essentially depend on the philosophical paradigm of the study. For research to be deemed credible, and to ensure there is no uncertainty on the integrity of the data, it is essential to achieve high validity. 2015 Jul;18(3):66-7. doi: 10.1136/eb-2015-102129.
