The conceptual model therefore had limited external validity but was still externally valid.
[ 22] In addition to the multiple sources of data, the strong critical review process ensures that the data have face validity and increase the likelihood that the data are representative and externally valid.
These results demonstrate that both measures have sound psychometric properties and are externally valid.
Most studies applying this methodology have provided little insight into how they created internally and externally valid written and role-played scripts.
Findings indicate that the scales are reliable, internally valid as demonstrated by confirmatory factor analysis, and externally valid in terms of relationships with students' control-value appraisals, learning, and academic performance.
However, given the lower levels of air pollution in developed countries, these estimates may not be externally valid to the developing country context if there is a non-linear dose relationship between pollution and mortality or if the costs of avoidance behaviour differ considerably between the two contexts.

The Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) was conceived in response to a National Institute of Mental Health initiative seeking a public health intervention model that could generate externally valid answers to treatment effectiveness questions related to bipolar disorder.
That is, are the simulation results externally valid?
Its aim was "to generate externally valid answers to treatment effectiveness questions related to bipolar disorder" (Sachs et al. 2003).
Therefore, the results and conclusions of our study should still be externally valid and generalisable to a certain extent for the population of orthodontists in Switzerland.
