APD occurred more frequently in Rels of Sz probands compared to CC probands (p < 0.001) and also when controlling for SPD and PPD (p < 0.005). Two Sxs of APD were most characteristic of the Rels of Sz probands: “avoids social or occupational activities…” and “exaggerates the potential difficulties…” 65% of the Rels of Sz probands who had diagnoses of APD were more than one criterion short of a DSM-III-R diagnosis of either SPD or PPD. This indicates that APD is a separate Sz-spectrum disorder, and not merely a sub-clinical form of SPD or PPD.
