The Cattell–Horn–Carroll theory factors that this test examines are based on 9 broad stratum abilities, although the test is able to produce 20 scores [4] only seven of these broad abilities are more commonly measured: comprehension-knowledge (Gc), fluid reasoning (Gf), short-term memory (Gsm), processing speed (Gs), auditory processing (Ga), visual-spatial ability (Gv), and long-term ...
The current version of the test, the WAIS-IV, which was released in 2008, is composed of 10 core subtests and five supplemental subtests, with the 10 core subtests yielding scaled scores that sum to derive the Full Scale IQ. With the WAIS-IV, the verbal/performance IQ scores from previous versions were removed and replaced by the index scores.
"FOUR" in this context is an acronym for "Full Outline of UnResponsiveness". The FOUR Score is a 17-point scale (with potential scores ranging from 0 - 16). Decreasing FOUR Score is associated with worsening level of consciousness. The FOUR Score assesses four domains of neurological function: eye responses, motor responses, brainstem reflexes ...
There is no assessment of executive function, phonemic fluency, or motor responses. It takes about half an hour to administer. [3] It was originally introduced in the screening for dementia, but has also found application in other situations, [3] such as hepatic encephalopathy. [4]
All items are scored from 0–7, with the exception of the orientation category, scored from 0–4. The CIWA scale is validated and has high inter-rater reliability. A randomized, double blind trial published in JAMA in 1994 [ 5 ] showed that management for alcohol withdrawal that was guided by the CIWA scale resulted in decreased treatment ...
A test score is a piece of information, usually a number, that conveys the performance of an examinee on a test. One formal definition is that it is "a summary of the evidence contained in an examinee's responses to the items of a test that are related to the construct or constructs being measured."
The test takes 45–90 minutes to administer depending on the age of the participant. The mean score for the WIAT-II is 100 with a standard deviation of 15, and the scores on the test may range from 40 to 160. 68% of participants in the UK standardisation sample obtained scores of 85-115 and 95% obtained scores of 70-130.
