Name of Instrument | Author | Number of Items | Dimensions | Reliability | Validity |
Structured Interview for DSM-III Personality Disorders (SIDP) | Pfohl, Stangl, & Zimmerman, 1983 |
| All DSM-III Personality Disorders | Test-retest reliabilities range between .24 - .74, with an average of .54. |
|
The Diagnostic Interview for DSM-IV Personality Disorders (DIPD-IV). | Zanarini, M. C., Frankenburg, F. R., Sickel, A. E., & Yong, L. (1996). | 108 | All DSM-IV Personality Disorders | Internal Consistency ranges between .64 to .93 Test-Retest Reliability ranges between .58 to 1.00 |
|
The Structured Interview for DSM-IV Personality Disorders (SIDP-IV) | Pfohl, Blum, & Zimmerman (1997) |
| All DSM-IV Personality Disorders | Interrater reliability for each of the PD criteria was generally more than 0.70. |
|
The Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II) | First, Gibbons, Spitzer, Williams, & Benjamin, 1997 | 140 | All DSM-IV Personality Disorders | Test-retest reliabilities have been found to range between .71 - .84 | The SCID-II/PQ was found to have moderate convergent validity with the NPD section of the SCID-II (Campbell & Miller, 2011). The SCID-II and the IPDE was shown to hold good convergent validity) .58 - .87; Skodol et al., 1991). |
Personality Disorder Interview (PDI-IV) | Widiger, Mangine, Corbitt, Ellis, & Thomas, 1995 |
| Semi-Structured Interview Questions for assessment of each of the 94 individual personality disorder diagnostic criteria are presented. |
|
|
International Personality Disorder Examination (IPDE) | Loranger, 1998; Loranger, 1999; Loranger et al., 1987 |
| The IPDE is a structured clinical interview that systematically surveys the phenomenology and life experiences relevant to the diagnosis of all DSM-IV Axis II (and ICD-10) personality disorders | Inter-rater reliabilities range between .81 - .92 (Lenzenweger, 1999). |
|
The International Personality Disorder Examination Questionnaire (IPDEQ) | 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). |
