Description
Wechsler Preschool and Primary Scale of Intelligence™-Fourth Edition (WPPSI™-IV) is a standardized tool designed to assess the cognitive development in preschool and young children (up to age 7 years and 7 months). The WPPSI™-IV consists of a battery of tests that allow an investigator to conduct a comprehensive evaluation of IQ. The WPPSI™-IV is a proprietary instrument and is available online from Pearson at www.pearsonclinical.com.
Specific Instructions
The Wechsler Preschool and Primary Scale of Intelligence™-Fourth Edition (WPPSI™-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 WPPSI™-IV and the Bayley Scales of Infant and Toddler Development®, Third Edition (Bayley-III®) and between the WPPSI™-IV and the Wechsler Intelligence Scale for Children®-Fifth Edition (WISC®-V). The Working Group recommends that 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 WPPSI™-IV, Bayley-III®, and the WISC®-V for guidance on selecting an age-appropriate test.

Protocol
Wechsler Preschool and Primary Scale of Intelligence™-Fourth Edition (WPPSI™-IV) is a tool designed to assess a child’s cognitive abilities and is administrated by a trained professional. The WPPSI™-IV consists of five primary and four ancillary index scales. The primary scales focus on working memory, processing speed, fluid reasoning, and visual, spatial, and verbal comprehension. The ancillary scales focus on general ability, cognitive proficiency, nonverbal, and vocabulary acquisition.
The WPPSI™-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 Preschool and Primary Scale of Intelligence™-Fourth Edition (WPPSI™-IV), and who 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 Preschool and Primary Scale of Intelligence™-Fourth Edition (WPPSI™-IV). The Sickle Cell Disease Neurology, Quality of Life, and Health Services Working Group acknowledges the WPPSI™-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.

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.
