Schedule for Nonadaptive and Adaptive Personality (SNAP) | Clark, 1993 | 375 items | All DSM-IV Personality Disorders | Test-retest correlation coefficients over 7 to 14 months ranged from .59 to .84. (Melley, et al., 2002) | Our results support the predictive validity of the diagnostic scales on the SNAP (Clark, 1993). SNAP scores can predict cluster A and C diagnoses. |
The Personality Diagnostic Questionnaire (PDQ) | Hyler et al., 1988 | 163 items | All DSM-III Personality Disorders | Internal consistency ranges between .43 - .70 (Hyler & Lyons, 1988). Test-retest reliabilities are greater than .56 (Hurt et al., 1984) |
|
The Personality Diagnostic Questionnaire Revised (PDQ-R) | Hunt & Andrews, 1992 | 152 items | All DSM-III Personality Disorders | Test-retest reliabilities are greater than .76 (Uehara et al., 1997) | The PDQ-R showed high sensitivity and moderate specificity for most axis II disorders (Hyler et al.,1992) |
The Personality Diagnostic Questionnaire 4th Edition (PDQ-4) | Hyler, 1994 | 99 items |
| Test-retest reliabilities averaging .67. | Compared to the SCID-II, Kappa levels were no lower than .50. The PDQ-4 demonstrated high sensitivity and low specificity. (Abdin et al., 2011) |
Coolidge axis-II inventory (CATI) | Coolidge, 1984 | 225 items | 13 Personality Disorder Scales (DSM-II) 3 Axis I Disorders | Excellent test-retest reliability (.90) has been established, as well as moderate internal consistency (.76). (Coolidge & Merwin, 1992). Watson & Sinha (1996)—a gender difference was found on the antisocial scale. Age differences were found for several PD scales in that younger respondents (17 - 24 years) scored higher than the older ones (25 - 57 years). The test has demonstrated reliability and validity and has been used in a variety of contexts, such as attributes of psychology majors in college (McCray, King, & Bailly, 2005). | The test has demonstrated reliability and validity and has been used in a variety of contexts, such as attributes of psychology majors in college (McCray, King, & Bailly, 2005), A 50% concordance rate with clinicians’ diagnoses for 24 personality-disordered out-patients was found (Coolidge & Merwin, 1992). |
Coolidge axis-two inventory (SCATI) | Coolidge, 2001 | 70 items | All DSM-IV Personality Disorders | Despite the scales being reduced from an average of approximately 25 items to 5 items in length, the SCATI has good internal reliability (Watson & Sinha, 2007) Multivariate analysis revealed that the internal structure of the SCATI is similar to the original. The SCATI is found to have good internal reliability. | PCA and CFA reveal that the internal structure of the test has dimensions similar to the full CATI. Therefore, the SCATI is an instrument of value for further research (Watson & Sinha, 2007) |
