External validity is the validity of applying the conclusions of a scientific study outside the context of that study. [1] In other words, it is the extent to which the results of a study can generalize or transport to other situations, people, stimuli, and times.
The Big Five model proposes that there are five basic personality traits. These traits were derived in accordance with the lexical hypothesis. [1] These five personality traits: Extraversion, Neuroticism, Agreeableness, Conscientiousness and Openness to Experience have garnered widespread support [dubious – discuss].
Naturalistic observation can also be used to verify external validity, permitting researchers to examine whether study findings generalize to real world scenarios. Naturalistic observation may also be conducted in lieu of structured experiments when implementing an experiment that would be too costly.
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]
Also known as external or criterion group method, empirical test construction attempts to create a measure that differentiates between different established groups. For example, this may include depressed and non-depressed individuals, or individuals high or low in levels of aggression.
Ecological validity, the ability to generalize study findings to the real world, is a subcategory of external validity. [ 6 ] Another example highlighting the differences between these terms is from an experiment that studied pointing [ 7 ] —a trait originally attributed uniquely to humans—in captive chimpanzees.
Validity [5] of an assessment is the degree to which it measures what it is supposed to measure. This is not the same as reliability, which is the extent to which a measurement gives results that are very consistent. Within validity, the measurement does not always have to be similar, as it does in reliability.
In 2002, the Journal of Psychology posted a Big Five Personality Trait Difference; where researchers explored the relationship between the five-factor model and the Universal-Diverse Orientation (UDO) in counselor trainees. (Thompson, R., Brossart, D., and Mivielle, A., 2002).
