Quizplus · Accepted Answer

Confounds or factors that make it difficult to interpret accurately the results of a study have a direct impact on internal validity. Internal validity refers to the degree to which a study accurately reflects a causal relationship between variables, and confounding variables undermine that relationship. Therefore, it is essential to control for confounds in order to increase a study's internal validity. Reliability is the extent to which a measurement is consistent or stable over time, and external validity is the degree to which study findings can be generalized to other populations or settings. While confounds can affect these aspects of a study as well, internal validity is the most directly affected. Whether or not the results are published is not related to the impact of confounds on interpreting the accuracy of a study's results.
