Estimating WAIS IQ from Shipley-Hartford scores: A cross-validation

Abstract

During the past year and one-half the present authors have studied the comparability of Shipley-Hartford total scores and WAIS Full Scale I&. Sines and Simmons (1) have recently publish-

Social skills deficits and self-evaluation among depressed and nondepressed psychiatric inpatients

“…The vocabulary section of the Shipley (Shipley, 1940) was used as a brief measure of verbal intelligence and vocabulary. Prior research has found high correlations between the Shipley and WAIS Full Scale scores (Sines & Simmons, 1959;Wiens & Banaka, 1960).…”

Estimating WAIS IQ from the shipley institute of living scale using continuously adjusted age norms

“…It also correlates very highly with most standard intelligence tests, including the Wechsler-Bellevue Adult Intelligence Scale (Garfield & Fey, 1948;Grayson, 1951;Sines, 1958;Wright, 1946), the Army General Classification Test (Sines, 1958;Watson & Klett, 1968), the Revised Beta Examination (Mack, 1970;Watson & Klett, 1968), the Raven Progressive Matrices (Eisenthal & Hartford, 1971), the Slosson Intelligence Test (Martin, Blair, Sadowski, & Wheeler, 1981;Martin, Blair, Stokes, & Lester, 1977), the Quick Word Test (Martin, Blair, & Vicker, 1979a), Form B of the Wide Range Vocabulary Test (Martin et al, 1979a), and the California Short-Form Test of Mental Maturity (Martin, Blair, & Vicker, 1979b). Correlations between Shipley Total scores and Full Scale IQ scores on the Wechsler Adult Intelligence Scale (WAIS; Wechsler, 1955) range from .73 to .90 with a median correlation of .80 across 10 studies (Bartz, 1968;Bartz & Loy, 1970;Paulson & Lin, 1970b;Sines & Simmons, 1959;Stone & Ramer, 1965;Suinn, 1960;Wahler & Watson, 1962;Watson & Klett, 1968;Wiens & Banaka, 1960;Winkler, 1981).…”

“…One problem is that several of the earlier procedures did not provide adequate age correlations (Bartz & Loy, 1970;Sines & Simmons, 1959;Wiens & Banaka, 1960). As noted by Paulson and Lin (1970a), these uncorrected formulae are most appropriate for individuals who are similar in age to the samples on which the prediction formulae were derived.…”
