Content validity is most often addressed in academic and vocational testing, where test items need to reflect the knowledge actually required for a given topic area (e.g., history) or job skill (e.g., accounting). In clinical settings, content validity refers to the correspondence between test items and the symptom content of a syndrome.
The validity of the design of experimental research studies is a fundamental part of the scientific method, [2] and a concern of research ethics. Without a valid design, valid scientific conclusions cannot be drawn.
Many psychologists and education researchers saw "predictive, concurrent, and content validities as essentially ad hoc, construct validity was the whole of validity from a scientific point of view" [15] In the 1974 version of The Standards for Educational and Psychological Testing the inter-relatedness of the three different aspects of validity ...

In qualitative research, a member check, also known as informant feedback or respondent validation, is a technique used by researchers to help improve the accuracy, credibility, validity, and transferability (also known as applicability, internal validity, [1] or fittingness) of a study. [2]
Some companies use the term 'linguistic validation' to refer to the entire process for the translation of PRO measures as described in the 'Principles of Good Practice' (Wild et al. 2005), [3] and the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Task Force report (Wild et al. 2009), [4] even if this process does not ...
The data collection instrument used in content analysis is the codebook or coding scheme. In qualitative content analysis the codebook is constructed and improved during coding, while in quantitative content analysis the codebook needs to be developed and pretested for reliability and validity before coding. [4]
Validity asks whether the research measured what it intended to. Content validation (also called face validity) checks how well the content of the research are related to the variables to be studied; it seeks to answer whether the research questions are representative of the variables being researched. It is a demonstration that the items of a ...
