Factors That Improve External Validity Consider psychological realism: Make sure that participants are experiencing the events of a study as a real event by Do reprocessing or calibration: Use statistical methods to adjust for problems related to external validity. For Replicate: Conduct the External validity is the extent to which results of a study can be generalized to the world at large. Sarah is worried that her study might have low external validity. Let's look closer at external External validity is an important concept to understand. A lack of understanding may doom your study, while strong external validity makes getting your dissertation accepted and/or article much easier to get published.
different themes.

Addressed problems are categorised into: 1) Lack of relevant information in scientific publications, and 2) studies

Time affects our ability to make generalisations.
