These scales grouped into the following categories: (i) rating scales predominantly covering depressive symptoms, (ii) rating scales predominantly covering psychotic symptoms, (iii) rating scales covering delusions, and (iv) rating scales covering PD. For the vast majority of the scales, the clinical and psychometric validity had not been tested empirically. The only exception from this general tendency was the 11‐item Psychotic Depression Assessment Scale (PDAS), which was developed specifically to assess the severity of PD.</p> </sec> <sec id="acps12449-sec-0004" sec-type="section"> <title>Conclusion</title> <p>In PD, the PDAS represents the only empirically derived rating scale for the measurement of overall severity of illness. The PDAS should be considered in future studies of PD and in clinical practice.</p> </sec> </abstract>
