127 Abbreviating the <strong>IPDE</strong><br />
Q. What about the criteria that are exempt from the 'past year' (12 months)<br />
requirement?<br />
A. The behaviour must have occurred at least once during the last five<br />
years. If it only occurred prior to the last five years, those employing the<br />
optional scoring for a 'past' personality disorder would score it positively,<br />
using the appropriate notation.<br />
Q. If I elect to score a criterion as 'past', must I determine whether it overlaps<br />
in time with the other criteria that are scored positively for that disorder?<br />
A. No. That would make the scoring too unwieldy, because the examiner<br />
would have to note the timeframe next to all positive ratings. The subject<br />
might also have difficulty recalling whether the behaviour associated<br />
with the various criteria overlapped in time.<br />
Q. Affirmative answers to questions that take the form, 'Have people told<br />
you that you're like that?,' are followed by. 'Why do you think they've<br />
said that?' How should replies to these follow-up questions be handled?<br />
A. Request examples. anecdotes, and descriptions. After any necessary<br />
probing, score the item according to the usual guidelines.<br />
Q. What if subjects endorse a trait or behaviour, but say that they are unable<br />
to provide examples?<br />
A. If despite encouragement they persist in saying so, then a positive score<br />
should not be given. This will result in occasional false-negative ratings,<br />
hut experience suggests that to deviate from the rule would probably lead<br />
to an unacceptable number of false-positive ratings. If subjects really<br />
have the trait to a clinically meaningful degree, they should be able to<br />
provide anecdotes or examples.<br />
Abbreviating the <strong>IPDE</strong><br />
This module of the <strong>IPDE</strong> is designed to assess all of the personality disorders<br />
in ICD-10, and the interview should be administered in its entirety<br />
whenever possible. Because of time constraints some users may be<br />
unable to give the complete interview to all subjects; others may be interested<br />
in only certain specific disorders. In those situations two options<br />
are available.<br />
The first option is to omit the items that do not pertain to the disorders<br />
of interest. In doing so, however, the examiner should always be sure to<br />
include the introductory, open-ended questions at the beginning of each
