Mitigating the Potential Threats of Internal Validity. The possible approaches of mitigating threats to external validity include the inclusion of an efficient design by adding treatment or control groups and differential waves of measurement (Haegele, & Hodge, 2015). On the other hand, a researcher may also consider the use of statistical analysis Experimental validity is an ideal to aspire to, for it is unlikely that it can ever be completely achieved. Internal validity is very difficult to achieve in the non-laboratory setting of the behavioral experiment in which there are so many extraneous variables to attempt to control. Threats to internal experimental validity Threats to internal validity are essentially threats to causal control. They mean that we do not know for sure what caused the effects that we observed.

clearing of viral infection with time) Unsurprisingly, experimental research tends to have the highest internal validity, followed by quasi-experimental research, and then correlational research, with case studies at the bottom of the list. Nonetheless, there are several potential threats to internal validity that are especially relevant to nonexperimental designs. A threat to internal validity is the issue of accurate and confident interpretation of its results that is at the center of the discussion of the validity according to (“Threats to internal and external validity – SlideShare.,” n.d.). A threat to internal validity is selection, which is selecting participants for various groups in a study. Mitigating the Potential Threats of Internal Validity. The possible approaches of mitigating threats to external validity include the inclusion of an efficient design by adding treatment or control groups and differential waves of measurement (Haegele, & Hodge, 2015). On the other hand, a researcher may also consider the use of statistical analysis Experimental validity is an ideal to aspire to, for it is unlikely that it can ever be completely achieved.

One Group Pre-Posttest Design This is a presentation of a pretest, followed by a treatment, and then a posttest where the difference between O1 and O2 is explained by X: O1 X O2 • Threats to internal validity that true experiments may not eliminate: o Contamination, o Experimenter expectancy effects, and o Novelty effects (including Hawthorne effect) • Threats to external validity occur when treatment effects may not be generalized beyond the particular people, setting, treatment, and outcome of the experiment.

The question of whether results from a particular study generalize to other people, places, or times arises only when one follows an inductivist research strategy. If the goal of a study is to deductively survey a theory, one is only concerned with factors which might undermine the rigor of the study, i.e. threats to internal validity.

Controlling confounding variables, in particular, can help achieve the best of everything. Threats to internal validity are important to recognize and counter in a research design for a robust study. Different threats can apply to single-group and multi-group studies. Internal validity threats reduce the likelihood of establishing a direct relationship between variables, Time-related effects, such as growth, can influence the outcomes, Carryover effects mean that the specific order of different treatments affect the outcomes.

Threats to internal validity may be a source of extraneous variance when the findings are not significant. External validity is addressed by delineating inclusion and exclusion criteria, describing subjects in terms of relevant variables, and assessing generalizability.
