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.

Coolidge axis-II inventory (CATI)

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).

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)
