The World Health Organisation

99 Items

1) Work,

2) Self,

3) Interpersonal relationships

4) Affects,

5) Reality testing,

6) Impulse control

The diagnosis of any PD was highly reliable with phi > .92. However, diagnosis of non-specific PD was not reliable at all (phi close to 0) suggesting that this is a true residual category. Diagnoses of specific PDs were highly reliable with the exception of schizoid PD. Diagnosis of antisocial and Borderline PDs were perfectly reliable with phi equal to 1.00 (Fountoulakis et al., 2002).
