Correlations were performed to examine whether the novelty P3 and target P3 in patients were related to the severity of depression or anxiety symptoms. There was no significant correlation between novelty P3 amplitude for patients at the midline parietal site (Pz) and depression scores on the BDI (r = 0.08, ns) or trait anxiety scores on the STAI (r = 0.07, ns). Similarly, there was no significant correlation between target P3 amplitude for patients at parietal site and scores on the BDI (r = 0.14, ns) or STAI (r = 0.04, ns).
