Description:

Wechsler Adult Intelligence Scale®, Fourth Edition (WAIS®-IV), is a standardized tool designed to assess an individual’s cognitive abilities. The WAIS®-IV consists of a battery of tests that allow an investigator to conduct a comprehensive cognitive evaluation of IQ. The WAIS®-IV is a proprietary instrument and is available online from Pearson at www.pearsonclinical.com.

Protocol:

Wechsler Adult Intelligence Scale®, Fourth Edition (WAIS®-IV), is a tool designed to assess an individual’s cognitive abilities and is administrated by a trained psychologist using a combination of verbal and performance tasks. The WAIS®-IV consists of a core battery of 10 subtests, which focus on specific intelligence domains (perceptual reasoning, processing speed, verbal comprehension, and working memory).

The WAIS®-IV is a proprietary instrument and is available online from Pearson at www.pearsonclinical.com.

Personnel and Training Required

The interviewer should be a licensed professional (or someone directly supervised by a licensed professional) who has been trained and is competent in the administration, scoring, and interpretation of standardized psychometric assessment tools, such as the Wechsler Adult Intelligence Scale®, Fourth Edition (WAIS®-IV), and meets the requirements of Qualification Level C for test use and administration.

Per the Pearson website, a test with a qualification of C, "require(s) a high level of expertise in test interpretation, and can be purchased by individuals with the following:

A doctorate degree in psychology, education, or closely related field with formal training in the ethical administration, scoring, and interpretation of clinical assessments related to the intended use of the assessment.

OR

Licensure or certification to practice in your state in a field related to the purchase.

OR

Certification by or full active membership in a professional organization (such as APA, NASP, NAN, INS) that requires training and experience in the relevant area of assessment.

Equipment Needs

The interviewer will require the Wechsler Adult Intelligence Scale®, Fourth Edition (WAIS®-IV). The Sickle Cell Disease Neurology, Quality of Life, and Health Services Working Group acknowledges the WAIS®-IV can be scored in a computerized format or a paper-and-pencil instrument. Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer/handheld computer to administer a computer-assisted questionnaire.

Individuals from 16 to 90 years old

Specific Instructions:

The Wechsler Adult Intelligence Scale®, Fourth Edition (WAIS®-IV) is a proprietary instrument and is available online from Pearson at www.pearsonclinical.com.

The Sickle Cell Disease Neurology, Quality of Life, and Health Services Working Group recognizes that there is an age overlap between the WAIS®-IV and the Wechsler Intelligence Scale for Children®-Fifth Edition (WISC®-V). The Working Group recommends providers use their clinical judgment, consider the purpose of testing participants, and refer to the frequently asked questions section of the Pearson website for the WAIS®-IV and the WISC®-V for guidance on selecting an age-appropriate test for individuals.

Selection Rationale

The Sickle Cell Disease Neurology, Quality of Life, and Health Services Working Group selected the Wechsler Adult Intelligence Scale®, Fourth Edition (WAIS®-IV), because it is a well-validated tool that yields IQ and various functional index scores.

Definition

This measure provides an estimate of an individual’s overall global intellectual function.

Purpose

Impairments in general cognitive function, as measured by the intelligence quotient (IQ), are associated with some genetic diseases (e.g., Down’s syndrome, Fragile X syndrome, sickle cell disease [SCD]), stroke, prematurity, nutritional deficiencies, and use of drugs and alcohol.
