About the Measure
Domain:
Sickle Cell Disease – Neurology, Quality of Life, and Health Services
Measure:
Intelligence Scale
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.

Protocol Text:
The Bayley Scales of Infant and Toddler Development®, Third Edition (Bayley-III®) is a
standardized tool designed to assess a child’s development as compared to sameage peers. The Bayley-III® has components that involve both direct observation and
interaction with a child as well as caregiver questionnaires. The Bayley-III® is a
proprietary instrument and is available online from Pearson at
http://www.pearsonclinical.com/.
The Sickle Cell Disease Working Group 2 (Neurology, Quality of Life, and Health
Services) selected the Bayley Scales of Infant and Toddler Development®, Third
Edition (Bayley-III®) because it is a well-validated, widely used instrument with an
objective, age-normed evaluation of developmental function.
The Bayley Scales of Infant and Toddler Development®, Third Edition (Bayley-III®) is a
proprietary instrument and is available on line from Pearson at
http://www.pearsonclinical.com/. A fee is associated with the Bayley-III®, and this fee
is dependent upon various factors, such as if the Bayley-III® is purchased as a kit (i.e.,
questionnaires, manuals, or forms) or in individual components.
The Sickle Cell Disease Working Group 2 (Neurology, Quality of Life, and Health
Services) recognizes that there is an age overlap between the Bayley-III® and the
Wechsler Preschool and Primary Scale of Intelligence™-Fourth Edition (WPPSI™ IV). 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 Bayley-III® and the WPPSI™-IV for
guidance on selecting an age-appropriate test.
The Bayley Scales of Infant and Toddler Development®, Third Edition (Bayley-III®)
consists of five domains (cognitive, motor, language, social-emotional, and adaptive
behavior).
The Bayley-III® is a proprietary instrument and is available on line from Pearson at
http://www.pearsonclinical.com/. A fee is associated with the Bayley-III®, and this fee
is dependent upon various factors, such as if the Bayley-III® is purchased as a kit (i.e.,
questionnaires, manuals, or forms) or in individual components.

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 Bayley-III® and who meets the requirements of Qualification Level C for test use
and administration.
These skills are typically part of the skill set of an individual with at least a master’s
degree. Professionals with the required training are usually speech and language
therapists, early interventionists, social workers, occupational and physical therapists
specializing in early intervention, developmental pediatricians, pediatric nurse
practitioners, psychologists, and psychiatrists.
The Bayley-III® has a qualification level of C. Per the Pearson website, tests with a
qualification of C “require a high level of expertise in test interpretation, and can be
purchased by individuals with the following:
Equipment Needs:
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.
The interviewer will require the Bayley Scales of Infant and Toddler Development®,
Third Edition (Bayley-III®). The Sickle Cell Disease Working Group 2 (Neurology,
Quality of Life, and Health Services) acknowledges that the Bayley-III® can be scored
in a computerized format or as 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.
