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]
Test validity is the extent to which a test (such as a chemical, physical, or scholastic test) accurately measures what it is supposed to measure.In the fields of psychological testing and educational testing, "validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests". [1]
People are thought to engage in both positive and negative attention seeking behavior independent of the actual benefit or harm to health. In line with much research and a dynamic self-regulatory processing model of narcissism, motivations for attention seeking are considered to be driven by self-consciousness and thus an externalization of ...
In other words, the relevance of external and internal validity to a research study depends on the goals of the study. Furthermore, conflating research goals with validity concerns can lead to the mutual-internal-validity problem, where theories are able to explain only phenomena in artificial laboratory settings but not the real world.

Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
People may have a strong, particular desire to become an ideal parent, succeed athletically, or create paintings, pictures, or inventions. [31] To understand this level of need, a person must not only succeed in the previous needs but master them. Self-actualization can be described as a value-based system when discussing its role in motivation.
Experiments that have high internal validity can produce phenomena and results that have no relevance in real life, resulting in the mutual-internal-validity problem. [6] [7] It arises when researchers use experimental results to develop theories and then use those theories to design theory-testing experiments. This mutual feedback between ...
[1] [2] [3] Construct validation is the accumulation of evidence to support the interpretation of what a measure reflects. [1] [4] [5] [6] Modern validity theory defines construct validity as the overarching concern of validity research, subsuming all other types of validity evidence [7] [8] such as content validity and criterion validity.
