Download PhenX Measures for Sickle Cell Disease (SCD) Research Project

Please take a moment to review and comment on the measures for sickle cell disease research
related to Neurology, Quality of Life, and Health Services proposed for the PhenX Toolkit
below. We welcome your feedback on this important initiative.
The PhenX (consensus measures for Phenotypes and eXposures) Toolkit
(www.phenxtoolkit.org) provides investigators with access to well-established, low burden,
standardized measures to incorporate into new or existing biomedical studies involving human
subjects. The goal of the Toolkit is to encourage use of common measures to help researchers
effectively collaborate and share data.
The 17 measures proposed by the PhenX Sickle Cell Disease Neurology, Quality of Life, and
Health Services Working Group (WG) are shown in the table below. A limited number of the
measures in this table can be added to the PhenX Toolkit, and the Working Group requests your
feedback to help guide decisions. The measures currently in the PhenX Toolkit relevant for
sickle cell disease research related to Neurology, Quality of Life, and Health Services are listed
after the table.

Profile
Description of Measurement Protocol
a. Adult: The Adult Sickle Cell Quality of Life Measurement Information
System (ASCQ-Me) Quality of Care Module is a set of 27 questions
administered to adults with sickle cell disease (SCD) to determine the
quality of care that they have received from health care providers.
b. Pediatric: The Consumer Assessment of Healthcare Providers and
Systems (CAHPS®) Health Plan Survey 4.0 Child Medicaid Questionnaire
includes general questions about access to care and quality of care and
additional questions about the services provided to children with chronic
conditions. Items CC1-CC38 of the questionnaire are version 4.0 of the
Children with Chronic Conditions Item Set.
a. Adult: This protocol includes 10 self-administered general health
questions from the PROMIS® Global Health item bank for adults and 29
Respond
Here:
Y/N
self-administered quality-of-life questions from the PROMIS® Profile 29
for adults. The quality-of-life questions include physical function, anxiety,
depression, fatigue, sleep disturbance, ability to participate in social
roles and activities, and pain intensity over the past seven days. Each
question, except for the pain questions, is measured on a five-point
scale.
b. Pediatric: This protocol includes seven self-administered from the
PROMIS® Pediatric Global Health item bank.
a. Adult: This protocol includes 30 self-administered questions from the
short form of the Adult Sickle Cell Quality of Life Measurement
Information System (ASCQ-Me). Domains covered include emotional
impact (5 items), social functioning impact (5 items), sleep impact (5
items), stiffness impact (5 items), pain episode (5 items), and pain
frequency (5 items).
b. Pediatric: The PedsQL™ Sickle Cell Disease Module includes 43 items
from 9 subscales: Pain and Hurt (9 items); Pain Impact (10 items); Pain
Management and Control (2 items); Worry (5 items); Worry II (2 items);
Emotions (2 items); Treatment (7 items); Communication I (3 items); and
Communication II (3 items). For all ages, each item asks how much of a
3. Quality of Life in problem there has been in the past month. There are self- or parentSickle Cell Disease reported forms for ages 8 to 18, and responses are scored on a five-point
Likert-style scale (0 = never a problem; 1 = almost never a problem; 2 =
sometimes a problem; 3 = often a problem; 4 = almost always a
problem). Forms for children ages 5 to 7 are interviewer-administered,
and responses include a three-point Likert-style scale (0 = not at all a
problem; 2 = sometimes a problem; 4 = a lot of a problem). Items are
reversed-scored and converted to a 100-point scale (0 = 100, 1 = 75, 2 =
50, 3 = 25, 4 = 0) with higher scores indicating better quality of life.
Scores for individual subscales are the sum of items divided by the total
number or items answered. The total score for the PedsQL™ Sickle Cell
Disease Module is the sum of the items divided by the number of items
answered.
The Sickle Cell Disease Self-Efficacy Scale is a nine-item, selfadministered questionnaire that measures disease-specific perceptions
of the ability to manage day-to-day issues resulting from sickle cell
4. Self-Efficacy in
disease (SCD). Items are scores according to a five-point scale ranging

various symptoms associated with a stroke and consists of 11 categories.
For each category, the test administrator asks the respondent to
perform an activity or respond to stimuli. Respondents receive a score
for each category based upon their ability to complete the activity or
respond to the action. Each score typically ranges from 0 to 3. Each
category of the NIHSS is designed to determine the respondent’s level of
consciousness (LOC), visual, motor, or language ability.
b. Pediatric: The Pediatric NIH Stroke Scale (PedNIHSS) is a physical
assessment of the various symptoms associated with a stroke and
consists of 11 categories. The PedNIHSS was developed by a panel of
pediatric and adult stroke experts and is a modification of the adult NIH
stroke scale (NIHSS). Modifications were made to allow individuals age
18 or younger to be assessed and are identified in the PedNIHSS by bold
italic text. For each category of the PedNIHSS, the examiner asks the
respondent to perform an activity or respond to an action by the
provider. Respondents receive a score for each category based upon
their ability to complete the activity or respond to the action. Each score
typically ranges from 0 to 3. Each category of the PedNIHSS is designed
to determine the respondent’s level of consciousness (LOC), visual,
motor, or language ability.
