It is important for a researcher to determine the mediators, moderators, and confounds that may affect a study before beginning an experiment. A mediator is a contributing variable which may have an effect on the pathway between the treatment/intervention and the outcome (Bauman, Sallis, Dzewaltowski, & Owen, 2002). Examples of mediators are strategies, support groups, or specific knowledge of a subject that may affect the outcome of the study. Moderators or modifiers can strengthen the relationship between a program and outcome; however, that strength depends on the presence of a third variable (Bauman, Sallis, Dzewaltowski, & Owen, 2002). In other words, a program or treatment may be beneficial to one group over another depending on the characteristics of the individuals in the group. A treatment that is more beneficial to women than men, and having a different overall and gender specific effect size is an example of a moderator. A confound allows the researcher to analyze the experiment and predict how the confound may affect the outcome of the study (Bauman, Sallis, Dzewaltowski, & Owen, 2002). Confounds tend to distort true degrees of an effect and influences the observed relationship between the treatment/program and the outcome (Bauman, Sallis, Dzewaltowski, & Owen, 2002). Gender can also be considered a cofounder. For example, males may be able to do certain physical activities easier than women; thus, making it less likely that some women will participate in a program that is physically too demanding.
