Definitions for "Intervening variable"
hypothetical variable that is not observed directly in research but, rather, is inferred from the relationship between the independent variable and the dependent variable (Shavelson, 1996).
A variable that causally links other variables to each other. In a causal model, this intermediate variable must be influenced by one variable in order for a subsequent variable to be influenced.
