Below is a selection of external threats that can help guide your conclusions on the generalizability of your research results: external validity The extent to which your results apply to populations/situations/times/environments different from those in your experiment… concept of generalizability The external validity of a particular study changes as more research is conducted in the same area; other studies may demonstrate that it was not very generalizable (that is, its external validity was weak) or that it proved to be very consistent in different settings (making its external validity strong). External validity will be used to denote the question whether the study results are valid for patients other than those in the original study population in a treatment setting that is in all respects equal to the treatment setting of the original study. External validity therefore involves patient and disease characteristics. Study results can be generalized to a specific target population if, and only if, the results are externally valid for this specific target population. External validity is a question of the generalizability of the results. If we replicate the study using different a sample, the study should still share similar results.
