In other words, the extent to which a research instrument consistently has the same results if it is used in the same situation on repeated occasions. The second measure of quality in a quantitative study is reliability, or the accuracy of an instrument. 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. In quantitative research, this is achieved through measurement of the validity and reliability. Rigour refers to the extent to which the researchers worked to enhance the quality of the studies. Consideration must be given not only to the results of the study but also the rigour of the research. So being able to critique quantitative research is an important skill for nurses. Evidence-based practice includes, in part, implementation of the findings of well-conducted quality research studies.
