This type of validity refers to the extent to which a test captures a specific theoretical construct or trait, and it overlaps with some of the other aspects of validity Construct validity does not concern the simple, factual question of whether a test measures an attribute. Experiments are generally high in internal validity because of the manipulation of the independent variable and control of extraneous variables. Studies are high in external validity to the extent that the result can be generalized to people and situations beyond those actually studied. Internal validity is concerned with control of extraneous variable, whereas external validity stresses on the applicability of the outcome to the practical situations. Internal validity ascertains the strength of the research methods and design. Conversely, external validity examines the generality of the research outcomes to the real world. Therefore, construct validity consists of obtaining evidence to support whether the observed behaviors in a test are (some) indicators of the construct (1).

External validity refers to the extent to which the results of a study can be generalized to other settings (ecological validity), other people (population validity) and over time (historical validity). External validity concerns the extent to which the (internally valid) results of a study can be held to be true for other cases, for example to different people, places or times.

Moving from finite, historically particular data to a general causal claim requires all three. It requires establishing not only internal validity but also establishing construct validity of the cause and outcome and external validity. This paper will contrast three types of validity: external validity, internal validity, and construct validity. It will identify the different threats to internal validity, external validity, and construct validity.

Internal and external validity are concepts that reflect whether or not the results of a study are trustworthy and meaningful. While internal validity relates to how well a study is conducted (its structure), external validity relates to how applicable the findings are to the real world. What is Internal Validity? Strong internal validity refers to the unambiguous assignment of causes to effects. Internal validity addresses causal control. External validity addresses the ability to generalize a study to other people and/or to other situations. Construct validity is about the correspondence between concepts (constructs) and the actual measurements.
