välittäjätekijät

Välittäjätekijät, often translated as mediating factors or mediators, are variables that explain the relationship between an independent variable and a dependent variable. In essence, they act as a bridge or pathway through which the independent variable influences the dependent variable. A mediator variable is not simply correlated with the outcome; it is hypothesized to be causally involved in the process.

The concept of mediation is crucial in understanding complex causal relationships across various fields, including psychology, sociology, and economics. For instance, if we are studying the effect of socioeconomic status on health outcomes, education level might serve as a mediating factor. Socioeconomic status might influence access to education, which in turn affects health literacy and preventive healthcare choices, ultimately impacting health outcomes.

Identifying mediating factors helps researchers to not only understand why a relationship exists but also to develop more targeted interventions. By targeting the mediator, one can potentially disrupt or alter the effect of the independent variable on the dependent variable. Statistical techniques such as regression analysis and structural equation modeling are commonly employed to test for mediation. It's important to distinguish mediators from moderators, which influence the strength or direction of the relationship between the independent and dependent variables, rather than explaining the pathway itself.
