External validity is also called generalizability. It refers to how easily the findings from a research study can be used in other settings or populations. While I don’t have specific access to research studies because I work as a translator, I can provide general information about concerns surrounding the study’s external validity.
A sample selection process is an aspect of research design that can reduce generalizability. If the study’s sample is not representative of the larger population, the results may not be generalizable. It may be impossible to apply the results to others if participants are from different age groups.
Another aspect of research design that can limit generalizability is the study’s method of data collection. The data collection process may be inconsistent or not reliable and the results might not be generalizable. Participants may give inaccurate or insufficient information if they self-report data.
Additionally, the study’s research design and methods might limit generalizability if they are too artificial or controlled. If a study was done in a laboratory, it may be difficult to apply the findings to actual-world scenarios. Also, it is possible that the results may not be generalizable if variables were manipulated in ways not consistent with how they might naturally occur.
In summary, there are several aspects of research design that can limit the generalizability of a study’s findings, including sample selection, data collection methods, and the artificiality of the research design itself. These factors must be considered by researchers when creating studies or interpreting the results in order to accurately represent the target population.
