Tables A. 1 to A.12 in the Appendix list the <strong>IPDE</strong> diagnoses at each individual<br />
centre. Table 5 presents the frequencies with which the specific<br />
DSM-111-R disorders occurred in the same patients. Table 6 provides the<br />
same information for the ICD-10 disorders.<br />
<strong>IPDE</strong> interrater reliability and temporal stability<br />
Intraclass correlation coefficients1 were used to measure the<br />
examiner-observer agreement in scoring each of the 157 items on the<br />
<strong>IPDE</strong>, and their stability from the initial to repeat examinations. Since<br />
stability is influenced by the interrater agreement in scoring a single<br />
interview, correlations with a correction for attenuationZ are included<br />
with the stability coefficients, to provide a more accurate estimate of stability<br />
per se. Table 7 summarizes these correlations. Tables A.13 and<br />
A.14 in the Appendix present the measures of interrater reliability and<br />
stability for each PD criterion in DSM-111-R and ICD-10, together with<br />
the frequency of occurrence of the criterion in the sample of 716<br />
patients.
