In other words, can you reasonably draw a causal link between your treatment and the response in an experiment? Internal validity refers to whether the effects observed in a study are due to the manipulation of the independent variable and not some other factor.

Construct validity of the psychological general well being

Internal validity can be assessed based on whether extraneous (i.e. unwanted) variables that could also affect results are successfully controlled or eliminated; the greater the control of such variables, the greater the confidence that a cause and effect relevant to the construct being investigated can be found.

In other words, can you reasonably draw a causal link between your treatment and the response in an experiment? Internal validity refers to whether the effects observed in a study are due to the manipulation of the independent variable and not some other factor. In-other-words there is a causal relationship between the independent and dependent variable. Internal Validity Internal validity occurs when a researcher controls all extraneous variables and the only variable influencing the results of a study is the one being manipulated by the researcher. This means that the variable the researcher intended to study is indeed the one affecting the results and not some other, unwanted variables. Internal validity refers to how well an experiment is done, especially whether it avoids confounding (more than one possible independent variable [cause] acting at the same time). The less chance for confounding in a study, the higher its internal validity is.
