The independent variable is the variable that is manipulated by the researcher, and in this case, it is the different treatments assigned to the patients. The dependent variable is what is being measured and affected by the independent variable, which in this case is the level of anxiety symptoms in the patients. Extraneous variables are variables that may affect the dependent variable, but are not being intentionally manipulated by the researcher, and control variables are variables that are kept constant throughout the study. Neither of these apply to the case described.
