Bivariate correlations among symptom indices are shown in
Table 1. As one would expect, symptom indices were positively
correlated. The correlations between symptoms of generalized
anxiety disorder with other anxiety disorders and depression were
particularly robust. The social phobia scale also had robust
correlations with the OCD and agoraphobia scales. As expected,
the panic disorder and agoraphobia scales were substantially
correlated with one another.
