The external validity and consistency of the study results.
Selection bias Heterogeneity Internal and external validity.
The concepts of internal and external validity were first introduced in Campbell 1957.
The quality of evidence was moderate with high methodological quality andlow external validity.
The authors point out the high external validity of the intervention;
Finally, external validity centers around whether the results of this experiment would generalize to other situations.
Methodological quality of evidence was low; external validity was moderate Evidence Report, Tab. 69.
Finally, external validity centers around whether the results of this experiment can be generalized to other situations.
The quality of evidence was moder-ate moderate methodological quality,moderate external validity; Evidence re- port, Tab. 2.
A detailed knowledge of internal and external validity is required to assess whether a clinical trial is“good”.
The external validity of qualitative research is not enhanced by the number of persons involved but by the variety of the sample.
Explanation: This criterion influences external validity, but not the internal or statistical validity of the trial.
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.
To optimize the external validity of our results, experiments will be carried out in two research facilities under similar housing and handling conditions.
The results illustrate that large search data from product andprice comparison sites has a larger external validity than search data from Google and Amazon.
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.
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. .
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.
To economically optimize the procedure and analysis,as well as the internal and external validity, we designed a computer-based short version(WinSPARK) with ToolBook.
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.
Compared with analog-age experiments,in digital-age experiments, it should be easier to address external validity empirically, and it should also be easier to ensure internal validity. .

The study design is unusual:Within the framework of an epidemiological approach with high level of external validity(i.e. investigations are carried out in the context of everyday therapy and authentic therapeutic relationships), nested randomised controlled studies were conducted to strengthen internal validity. .
The idea of mediators is captured by what I call mechanisms,and the idea of moderators is captured by what I call external validity(e.g., would the results of the experiment be different if it was run in different situations) and heterogeneity of treatment effects e.g., are the effects larger for some people than other people.

For external users validity ends when no library loan services have been exercised within two consecutive calendar years.
Create upload and download links with limited validity for external partners and send them directly from the web application or your local mail client.
