I had to read the following article: Boyle, M. A., Augustine, J. J., Garton, E. M., Sharp, D. S., & Mansfield, H. M. (2022). Incorporating noncontingent reinforcement into functional communication training. Behavioral Development, 27(1-2), 43-52. https://doi.org/10.1037/bdb0000109 .

What are three factors to consider when assessing the external validity of a study?

Link to the article is attached below.
