External validity and internal validity often conflict (Cozby 2014). Since internal validity is based on a cause and effect relationship between specified variables, if that is what the researcher seeks to identify, then there is a strong case for establishing internal validity (Cozby 2014).

Two major types of experimental validity are considered here: internal validity and external validity. Internal Validity. Internal validity refers to whether the experimental treatment was the sole cause of observed changes in the dependent variable. In other words, internal validity addresses the ‘true’ causes of outcomes that we observe Internal validity is the extent of the ability to attribute the observed effect to the experimental variable, and not to other factors. External validity is the extent to which the effect can be generalized.

The following general categories of validity can help structure its assessment: Internal validity. This is about the validity of results within, or internal to, a study. External validity and internal validity often conflict (Cozby 2014). Since internal validity is based on a cause and effect relationship between specified variables, if that is what the researcher seeks to identify, then there is a strong case for establishing internal validity (Cozby 2014). Internal validity can be improved by controlling extraneous variables, using standardized instructions, counter balancing, and eliminating demand characteristics and investigator effects. 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).

Also note that research can still have internal and external validity without doing these, though you'd have to make a strong argument as to why. As a final note, let me add this: you don't ever "have" internal or external validity, you merely have evidence supporting internal/external validity.

It lacks external validity. Because it has good internal validity, I can generalize the results to highly active pregnant women—just not to all pregnant women. Threats to External Validity.

External validity is addressed by delineating inclusion and exclusion criteria, describing subjects in terms of relevant variables, and assessing generalizability. internal validity) we are making the experiment more and more artificial and thereby it’s generalizability (external validity) suffers. An exception would be in reference to specific control techniques e.g. the balance technique would allow for more generalizability than would the eliminate or hold constant techniques Internal validity refers to the degree of confidence that the causal relationship being tested is trustworthy and not influenced by other factors or variables.External validity refers to the extent to which results from a study can be applied (generalized) to other situations, groups or events. Internal Validity: Internal quality is the extent to which the researcher can make the claim that no other variables besides the one, under study, caused the result.
