The general question is whether we can take measures of IQ, normed with a normal sample, and then validly use them asindicators of the same constructs with samples significantly different from the normed sample. In previous papers it was pointed out that the pattern structurally simple &gt; moderately complex &gt; complex tests can be observed in their IQ profiles within both the Verbal scale and the Performance scale. In this paper, it is hypothesized that this scatter of scores leads to an underestimation of the global V\u2013P IQ differences for children with language\u2013related disorders because there are more structurally complex tests on the Performance scale than on the Verbal scale. To test this hypothesis, \u201cpurer\u201d V\u2013P IQ differences were calculated by comparing the scores on Verbal and Performance tests of equal structural complexity. WPPSI and WISC\u2013R data from four groups of children were analyzed: language\u2013impaired children (<jats:italic>n<\/jats:italic>= 128), reading\u2013impaired children (<jats:italic>n<\/jats:italic>= 112), children from dyslexic families (<jats:italic>n<\/jats:italic>= 51), and normal children (<jats:italic>n<\/jats:italic>= 49). When the effect of the difference in structural complexity was controlled for, it was found that the distribution of the revised V\u2013P IQ difference was significantly more toward the negative end of the spectrum than the traditional V\u2013P IQ differences for language\u2013impaired and reading\u2013impaired children, and approaching a significant level for children from dyslexic families. As hypothesized, there were no significant differences between the two distributions of V\u2013P IQ differences for normal children. Practical and theoretical implications are discussed.<\/jats:p>","DOI":"10.1111\/1467-9450.00297","type":"journal-article","created":{"date-parts":[[2003,3,12]],"date-time":"2003-03-12T20:24:43Z","timestamp":1047500683000},"page":"291-298","source":"Crossref","is-referenced-by-count":6,"title":["Do the Wechsler scales underestimate the difference between verbal and performance abilities in children with language\u2013related disorders?"],"prefix":"10.1111","volume":"43","author":[{"given":"Ernst","family":"Ottem","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,6,28]]},"container-title":["Scandinavian Journal of Psychology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2F1467-9450.00297","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1467-9450.00297","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1467-9450.00297","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,11]],"date-time":"2023-09-11T05:45:56Z","timestamp":1694411156000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/1467-9450.00297"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2002,9]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2002,9]]}},"alternative-id":["10.1111\/1467-9450.00297"],"URL":"https:\/\/doi.org\/10.1111\/1467-9450.00297","archive":["Portico"],"relation":{},"ISSN":["0036-5564","1467-9450"],"issn-type":[{"value":"0036-5564","type":"print"},{"value":"1467-9450","type":"electronic"}],"subject":[],"published":{"date-parts":[[2002,9]]}}}
