The tripartite model of depression and anxiety suggests that depression and anxiety possess shared (generalized negative affect) and specific (low positive affect and physiological hyperarousal) components. In one of the first studies to examine the model using LISREL confirmatory factor-analytic techniques and an array of different self-report measures, 205 undergraduates completed measures of depression, anxiety, self-esteem, and positive and negative affect. Consistent with the tripartite model, a three-factor model—with depression, anxiety, and negative affect as factors—provided a good fit to the observed data, whereas one- and two-factor models did not. In the three-factor model, low positive affect was a specific indicator of depression; physiological hyperarousal was a specific indicator of anxiety; and nonspecific indicators, such as negative mood, made up the negative affect factor.
