Clarifying Problems and Offering Solutions for Correlated Error when Assessing the Validity of Selected-Subtest Short Forms
Peer reviewed Peer reviewed

Girard, Todd A.; Christensen, Bruce K. – Psychological Assessment, 2008
The correlation between a short-form (SF) test and its full-scale (FS) counterpart is a mainstay in the evaluation of SF validity. However, in correcting for overlapping error variance in this measure, investigators have overattenuated the validity coefficient through an intuitive misapplication of P. Levy's (1967) formula. The authors of the…

A Short Form of the WISC-III for Clinical Use.
Peer reviewed Peer reviewed
Donders, Jacques – Psychological Assessment, 1997
Eight subtests were selected from the Wechsler Intelligence Scale for Children--Third Edition (WISC-III) to make a short form for clinical use. Results with the 2,200 children from the WISC-III standardization sample indicated the adequate reliability and validity of the short form for clinical use. (SLD)

Validity and Time Savings in the Selection of Short Forms of the Wechsler Adult Intelligence Scale--Revised.
Peer reviewed Peer reviewed
Ward, L. Charles; Ryan, Joseph J. – Psychological Assessment, 1996
Validity and reliability were calculated from data in the standardization sample of the Wechsler Adult Intelligence Scale--Revised for 565 proposed short forms. Time saved in comparison with use of the long form was estimated. The most efficient combinations were generally those composed of subtests that were quick to administer. (SLD)

Validation of Kaufman, Ishikuma, and Kaufman-Packer's Wechsler Adult Intelligence Scale-Revised Short Forms on a Clinical Sample.
Peer reviewed Peer reviewed
McCusker, Paul J. – Psychological Assessment, 1994
Three short forms of the Wechsler Adult Intelligence Scale-Revised (WAIS-R), developed in 1991, were cross-validated on 207 male and 133 female adolescent psychiatric inpatients and outpatients. Results show psychometric properties for the short forms that are comparable to those of the WAIS-R standardization sample. (SLD)

Psychometric Evaluation of the Beck Depression Inventory-II.
Peer reviewed Peer reviewed
Dozois, David J. A.; Ahnberg, Jamie L.; Dobson, Keith S. – Psychological Assessment, 1998
Provides psychometric information on the second edition of the Beck Depression Inventory (BDI-II) (A. Beck, R. Steer, and G. Brown, 1996) for internal consistency, factorial validity, and gender differences. Results indicate that the BDI-II is a stronger instrument than its predecessor in terms of factor structure. (SLD)

Development and Validation of a Computer-Administered Version of the Hamilton Anxiety Scale.
Peer reviewed Peer reviewed
Kobak, Kenneth A.; And Others – Psychological Assessment, 1993
A developed computer-administered form of the Hamilton Anxiety Scale and the clinician form of the instrument were administered to 214 psychiatric outpatients and 78 community adults. Results support the reliability and validity of the computer-administered version as an alternative to the clinician-administered version. (SLD)

Concurrent Validity of Three WAIS-R Short Forms in Psychiatric Inpatients.
Peer reviewed Peer reviewed
Benedict, Ralph H. B.; And Others – Psychological Assessment, 1992
The concurrent validities of 3 short forms of the Wechsler Adult Intelligence Scale (WAIS) were compared for their prediction of full-scale IQ for 145 male and 159 female psychiatric inpatients. Results support previous research showing better predictive accuracy for L. C. Ward's (1990) seven-subtest short form than the others. (SLD)
