The concepts of internal and external validity were first introduced by Campbell(1957).
External validity focused on the generalizability of the study findings.
Rather, the content of CONSORT focuses on items related to the internal and external validity of trials.
One aspect of external validity is the setting in which an intervention is tested.
For most well-designed and well-run experiments,concerns about external validity are the hardest to address.
One aspect of external validity is the setting in which an intervention is tested.

Finally, external validity centers around whether the results of this experiment would generalize to other situations.
Gresham and MacMillan(1997, 1998)expanded on the threats to both internal and external validity raised by Schopler et al.
Finally, external validity centers around whether the results of this experiment would generalize to other situations.
Fortunately, the digital age enables researchers to move beyond these data-free speculations and assess external validity empirically.
The fact that the same pattern appeared in many systems increases the external validity of these results because it reduces the chance that this pattern is an artifact of any particular system.
Fortunately, the digital age enables researchers to move beyond these data-free speculations and assess external validity empirically.
Evaluating external validity is particularly crucial as research into homeopathy is often done by doctors and scientists with little understanding of how it should be used or which treatments work best for which patients.
Other aspects of the setting(including the social, economic, and cultural environment and the climate)may also affect a study's external validity.
Compared to analog age experiments,in digital age experiments it should be easier to address external validity empirically and it should be easier to ensure internal validity. .
See Shadish, Cook, and Campbell(2001) for a more detailed history and a careful elaboration of statistical conclusion validity, internal validity, construct validity, and external validity.

In both of these projects everything will happen in the“real world”- in everyday clinical practice, without changing the practice in order tomake research possible- which is my ideal for research having good external validity.
First, researchers will be able to empirically address concerns about external validity when the cost of running experiments is low, and this can occur if the outcome is already being measured by an always-on data system.

The Swiss scientists had two major criteria for judging study quality:internal validity(quality of the study design and execution); and external validity(how accurately the studies reflect the use of homeopathy in real life).
In the past, these debates about external validity were frequently just a bunch of people sitting in a room trying to imagine what would have happened if the procedures were done in a different way, or in a different place, or with different people.
The idea of mediators is captured by what I call mechanisms, andthe idea of moderators is captured by what I call external validity(e.g., would the results of the experiment be different if it were run in different situations) and heterogeneity of treatment effects(e.g., are the effects larger for some people than for others).

In the past, these debates about external validity frequently involved nothing more than a group of people sitting in a room trying to imagine what would have happened if the procedures had been done in a different way, or in a different place, or with different participants.
