Scores from two (Vocabulary, Block Design) and four (Arithmetic, Vocabulary, Block Design, and Picture Arrangement) subtest short forms of the WAIS—R were compared with the Full Scale IQs for vocational rehabilitation clients, 305 mentally retarded, emotionally disturbed, and physically handicapped subjects. Some large differences between mean IQs, some low correlations between IQs once corrected for spuriousness, and high misclassification rates suggest caution in using the short-form IQs. Use of the Full Scale IQ for screening vocational rehabilitation clients is recommended.

The WISC—RM subtest scores of 63 second and third graders of Superior and Very Superior abilities in the public schools of the Federal District of Mexico were analyzed to assess which short forms most effectively predict Full Scale IQs. The Similarities—Picture Arrangement (S—PA) dyad, and the Similarities—Vocabulary—Picture Arrangement (S—V—PA), and Vocabulary—Block Design—Picture Arrangement (V—BD—PA) triads were the best over-all predictors of Full Scale IQ. The best single short-form combination appears to be Similarities—Vocabulary—Picture Arrangement (S—V—PA).

The purpose of the present study was to validate the effectiveness of three forms of abbreviated WISC-Rs. 100 protocols from a group of mentally retarded and language/learning impaired children were rescored according to three different methods of abbreviation previously used with the WISC. Part-whole correlations, correlations of IQs from the original and short-forms, were quite high for each of the short-form methods, ranging from .92 to .93 for the Full Scale IQ. Though tests for significance between correlations demonstrated no statistically significant differences, the accuracy of the Finch, et al. method (1973) was superior in estimating IQ. All three methods are derived from complete administration of the WISC-R.

A short form of the WISC was investigated for use with mentally retarded children. WISC records of 70 Ss were rescored using an abbreviated procedure; correlations with the original ranged from .80 on Picture Completion to .90 on Block Design with correlation of .95, .95, and .91 for the Verbal, Performance, and Full Scale respectively.

Short-forms of Wechsler intelligence tests have abounded in the literature and have been recommended for use as screening instruments in clinical and research settings. Clinicians who administer short-forms as screening devices are concerned with the accuracy of the resulting IQ estimate. LoBello recently recommended that subtest scatter might serve as an indicator that the resulting short-form IQ does not accurately estimate the IQ based on the entire scale. In this study, the data from 69 children who had taken the WPPSI—R were used to estimate the correlation for the differences between Full Scale WPPSI—R IQs on the complete test and on the short-form (four subtests) and the differences between the subtests with the highest and lowest scaled scores. The Pearson r of .02 indicates that subtest scatter is not related to the accuracy of the short-form IQ and will not reliably alert clinicians to the need to administer the entire battery.

We compared the retest stability of selected WAIS-R short forms including the Kaufman, Ishikuma, & Kaufman-Packer; Reynolds, Wilson, and Clark; and Silverstein tetrads; and the Ward seven subtest abbreviation. Subjects were 61 normals with means for age and education of 78.93 years ( SD = 3.46) and 9.74 years ( SD = 1.91), respectively. The average retest interval was 65 days. Stability coefficients were .87, .94, and .89 for the Kaufman, Reynolds, and Silverstein tetrads, respectively. Coefficients on Ward's abbreviation were .88 on the Verbal, .91 on the Performance, and .93 on the Full Scales. Retest means changed by 3.03 points on Kaufman, -.38 on Reynolds, and .56 on Silverstein. Average changes were 2.36, 3.49, and 3.36 on the Ward Verbal, Performance, and Full Scale estimates. Short form stability in each instance was comparable to that of the standard WAIS-R.

Components Analysis

Three short forms of the Marlowe-Crowne Social Desirability Scale were constructed from the results of principal components analysis ( N = 399). Those subscales were compared with short forms developed by previous researchers who used the same methodology. Examination of the subscales indicated that 13 of the scale's 33 items were isolated by at least two of the three reported studies. Those items were used to construct a composite subscale, which appeared to offer a useful alternative to the full scale. Further analysis of the subscale's contents, however, raised questions about the dimensionality of the Marlowe-Crowne scale. Caution was urged in the use and interpretation of both the full inventory and the short form until the meaning of scale scores can be clarified.

Wechsler Adult Intelligence

Although the Escala de Inteligencia Wechsler (EIWA) has remained the only standard Spanish version of the Wechsler Adult Intelligence Scale (WAIS) and is consequently the most often-used intelligence test with Spanish-speaking clients, little information exists on the psychometric properties of the test beyond the information in the test manual (Wechsler, 1968). There is no information on the validity or reliability of commonly used short forms of the test, the two-test version using Block Design and Vocabulary, and the four-test version using Block Design, Vocabulary, Arithmetic, and Picture Arrangement. Using the statistical data in the test manual, the two-test version yielded reliabilities of .94 to .95 across the three standardization age groups and validity ratings of .92 to .93. Values for the four-test version were slightly higher, and all were comparable to those for the WAIS and WAIS–R. The results suggest that the short forms can be used with the same confidence with the Spanish WAIS as on the WAIS.

Scale Data

A short-form intelligence test is commonly validated by determining irs correlation with the full scale from which it is taken, but it has been argued that this measure is less meaningful than the extent to which the short form agrees with the full scale in classifying individuals. A table is presented showing the theoretical agreement between the best duad, triad, tetrad, and pentad short forms of the WAIS and the Full Scale. Data on agreement may be more helpful than correlational data to the clinician who must decide whether to use a short form in place of the Full Scale.

Wechsler Adult Intelligence

The accuracy of different subtest combinations in predicting Verbal, Performance, and Full Scale IQ, scores on the revised edition of the Wechsler Adult Intelligence Scale (WAIS-R) was examined. A best subset multiple regression technique with sample sizes ranging from 1,062 to 1,084 individuals was used. All possible subtest combinations were analyzed to determine the ones that showed the three best and the single worst multiple Rs with IQ scores from the complete WAIS-R. All short forms provided accurate estimates of Full Scale scores, and predictive accuracy increased slightly as more subtests were used. The data suggest that statistically searching for a “best” short form is largely futile. Short forms should be selected on the basis of their efficiency to provide the information required.
