The Wechsler Adult Intelligence Scale Fourth UK Edition (WAIS-IV UK) is an individually administered clinical instrument designed to assess the cognitive ability of adolescents and adults aged 16 to 90 years. The WAIS-IV is a revision of the WAIS-III. Includes Administration and Scoring Manual, Technical Manual, 2 Stimulus Books, 25 Record Forms, 25 Response Booklet 1, 25 Response Booklet 2, Symbol Search Scoring Key, Coding Scoring Key, Cancellation Scoring Templates, Block Design Cubes, Scoring Software. In addition to the inclusion of 3 new subtests, there are changes to the administration of several other subtests, and to the recording and scoring of most of them. The converted scores then replace the scaled scores of the corresponding subtests on the WAIS IV to derive the new composite estimates. WAIS-IV-CDN Complete Kit in Box with Scoring Assistant 774755709 Qualification Level C. The WAIS-IV provides estimates of Full-Scale IQ, an overall measure of intellectual ability, and four composite Index scores that provide measures of component abilities: Verbal Comprehension, Perceptual Reasoning, Working Memory and Processing Speed. However, the Verbal IQ and Performance IQ scores provided by earlier versions of the WAIS have been discontinued (similar to the changes in the WISC-IV). In addition to Full-Scale IQ the WAIS-IV also provides a General Ability Index, which is derived from the Verbal Comprehension and Perceptual Reasoning Indices. This provides a measure of intellectual ability that is less dependent on working memory and processing speed, which might be more appropriate for some populations (e.g. Clinical training programs may use this chapter with new trainees to provide an overview of administration and scoring issues that are both common to the Wechsler intelligence. Where neuropsychological problems with working memory or physical problems affecting processing speed are evident). This chapter presents practical issues to consider when administering and scoring the Wechsler Adult Intelligence Scale Fourth Edition (WAIS-IV Wechsler, 2008 ).
