Description

The CAT is designed for use as part of a neurological assessment test battery, as a measure of executive function.

This instrument is a computerised version of the Halstead Category Test.  It is designed to assess problem-solving capacity, or the ability to search for and discover alternative solutions to novel problems.

The Halstead-Reitan Neuropsychological Test Battery is one of the most widely used neuropsychological assessment tools, of which the Halstead Category Test (HCT) is a part.  The computerised version of this test provides the administrator with many advantages.  If test administrators currently use the large, bulky, manual apparatus, they could save space, and time by switching to the computer versions.

Key Areas Measured

  • Executive Functioning
  • Problem Solving
  • Brain damage and cognitive impairment abstraction
  • Visuospatial skills

Child psychologists, clinicians and other mental health professionals will benefit from the following:

  • Availability of 4 computer-adapted versions: The Halstead Category Test (HCT), the Adaptive Category Test (ACAT), the Russell Revised Short Version (RCAT), and the Intermediate Category Test (ICAT)
  • Automatic Scoring and immediate feedback

The test involves presentation of figures on a computer screen.  Respondents select keys 1, 2, 3, or 4 on the keyboard to respond to the test items.  The CAT has four computer-adapted versions the Halstead Category Test (HCT), the Adaptive Category Test (ACAT), the Russell Revised Short Version (RCAT) and the Intermediate Category Test (ICAT).

The HCT is appropriate for individuals agred 16-69.    The HCT is the full computer based software version of the Halstead Category Test.  This version typically takes 30-40 minutes to administer.

The ACAT is appropriate for individuals aged 16-69.  This interactive, computer version of the CAT uses built-in archival data to compare a subset of responses on items of a subtest to statistically-derived clusters of similar response patterns collected from previous respondents.  The ACAT then uses a matched statistical group to accurately predict the respondent's final score for that subtest.

The RCAT is appropriate for individuals aged 16-69.  This test groups the 95 figures of the HCT into 6 subtests.  This version of the CAT was shortened by discarding the memory subtest, reducing half the numbers of items from most subtests.  When multiplied by 2.2 the number of errors across the short and full versions of the test are comparable.

The ICAT is designed for youth aged 9-15.  It contains 168 items organised into 6 different subtests.
