The anxiety symptoms 2 months later are being measured and are therefore the dependent variable in the study. The independent variable is the different treatments being assigned to the patients, and the control group with no treatment serves as a reference point for comparison. Extraneous variables are factors that may impact the dependent variable, but are not being intentionally manipulated in the study. Control variables are any factors being intentionally kept constant throughout the study.
