Objectives: In this article, we focus on how systematic reviews address external validity. External validity refers to the extent to which the results of a study can be generalized to other settings (ecological validity), other people (population validity) and over time (historical validity).

When making generalisations that involve time, we need to not only think about the threats to external validity that arise from making generalisations across time, but also the fact that time is a part of the treatment (i.e., intervention) within quantitative research (e.g., a 15 week teaching period versus a 3 year External validity is important in psychology studies - it measures the extent to which an experiment can be generalised to create general rules that can be applied in other, real life situations.
