The Wechsler Adult Intelligence Scale®: Canadian with Canadian norms is the gold–standard assessment instrument to measure cognitive ability in adults. The new fourth edition, the WAIS®–IVCDN, builds on the solid psychometric properties and features of its predecessor while offering valuable revisions and enhancements to provide you with the most advanced measure of cognitive ability–and results you can trust.

Norms to Age 90

The new WAIS®–IVCDN, includes normative data for ages 16 to 90, based on a fully stratified representative Canadian sample. Special attention was paid to the assessment of older adults, enhancing the clinical utility for the aging population.

Improved Psychometric Properties

Besides updated norms, the WAIS®–IVCDN, features improved subtest and composite reliability as well as reduced item bias. It also has improved floors and ceilings to enhance its specificity in testing individuals with higher and lower cognitive functioning. New optional index scores reflect current research and theory.

Updated Structural Foundations

  • Transitioned from Dual IQ to Index Score Structure–Consistent with the WPPSI®–IIICDN and WISC®–IVCDN , fewer subtests yield FSIQ and 4 Index Scores (Verbal Comprehension, Perceptual Reasoning, Working Memory, Processing Speed)
  • Inclusion of Growth/Decline Scores
  • Renamed Perceptual Organization Index (POI) as the Perceptual Reasoning Index (PRI)
  • New Measure of Fluid Intelligence–New subtests measure fluid reasoning (Visual Puzzles and Figure Weights)
  • Enhanced Measure of Working Memory–Revised Arithmetic subtest to emphasize Working Memory; revised Digit Span subtest to emphasize Working Memory by adding a Digit Sequencing task; retained auditory Working Memory measures
  • Improved Measure of Processing Speed–Reduced fine motor demands; inclusion of additional supplemental subtest (Cancellation)

Increased Developmental Appropriateness and User Friendliness

  • Reduced administration time to effectively increase the diagnostic utility of the WAIS®–IVCDN
  • Revised instructions as well as added demonstration and sample items to ensure clarity and proper understanding of tasks
  • Reduced vocabulary-level for verbatim instructions
  • Reduced emphasis on motor demands and timed performance
  • Enlarged visual stimuli
  • Expanded sample responses
  • Simplified technical manual organization
  • Redesigned record form
  • Increased test portability
  • New clinically sensitive supplemental subtests

Clinical Utility

The WAIS®–IVCDN clinical group studies include adults with clinical diagnoses of mental retardation, hearing impairment, reading disability, math disability, attention-deficit/ hyperactivity disorder, schizophrenia, traumatic brain injury, chronic alcohol abuse, Huntington's disease, Korsakoff's syndrome, Parkinson's disease, and Alzheimer's disease. In addition, the fourth edition now also includes adults with mild impairment and borderline intellectual functioning.

Validity and Linking Studies with the New WAIS®–IVCDN, WF:ASCDN, WIAT–II, and Upcoming WIAT–IIICDN

The WAIS®–IVCDN includes a validity study with the new WMS–IVCDN as well as a linking study with the new WF:ASCDN to allow you to conduct ability-achievement discrepancy analysis. It also includes a linking study with the WIAT–II, using U.S. correlation data, for ages 16–19:11, as well as the upcoming WIAT–IIICDN. The General Ability Index (GAI) is also provided.
