Peer reviewed research studies have already been evaluated by experienced researchers with relevant expertise.

Validity and Reliability in Social Science Research.

The importance of measuring the accuracy and consistency of research instruments especially questionnaires known as validity and reliability, respectively, have been documented in several studies, but their measure is not commonly carried out among health and social science researchers in developing countries.

This has been linked to the dearth of knowledge of these tests. This is a review article which comprehensively explores and describes the validity and reliability of a research instrument with special reference to questionnaire. 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.

Understanding Validity in Sociology

The Validity and Reliability of the scales used in research are essential factors that enable the research to yield beneficial results. For this reason, it is useful to understand how the Reliability and Validity of the scales are measured correctly by researchers. The primary purpose of this study is to provide information on how the researchers test the Validity and Reliability of the scales used in their empirical studies and to provide resources for future research. For this purpose, the concepts of Validity and Reliability are introduced, and detailed explanations have been provided regarding the main methods used in the evaluation of Validity and Reliability with examples taken from the literature. It is considered that this study, which is a review, will attract the attention of researchers. Student, European Leadership University.


In other words, reliability is the extent to which measurements are repeatable – when different persons perform the measurements, on different occasions, under​.


VALIDITY AND RELIABILITY IN QUANTITATIVE RESEARCH
