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].
Research suggests that the same five-factor structure of personality can be found in multiple other countries, based on a translated version of the Revised NEO Personality Inventory. [5] Studies on the validity of the Five-Factor Model using translations of the Revised NEO Personality Inventory have found broad support across many studies and ...
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).
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.
The student validation sample consisted of 396 undergraduate psychology students attending the same university as members of the scale development sample. All members of this sample This sample was similar to the scale development sample in terms of age and ethnicity, 30% White/Caucasian, 46% Asian/Asian-American, 8% Hispanic/Latino, 2% Black ...
Conducting field experiments allows researchers to make causal inferences from their results, and therefore increases external validity. However, confounding may decrease internal validity of a study, and ethical issues may arise in studies involving high-risk. [2]
Validity has two distinct fields of application in psychology. The first is test validity (or Construct validity ), the degree to which a test measures what it was designed to measure. The second is experimental validity (or External validity ), the degree to which a study supports the intended conclusion drawn from the results.
