Measures for Social and
Behavioral Determinants of
Health

Different, but the Same
The NIH seeks proposals for innovative approaches to
measuring patient-reported outcomes (PROs). . . across a
wide variety of chronic disorders and diseases.
Develop and test a large bank of items measuring PROs
Create a computerized adaptive testing system that will
allow for efficient, psychometrically robust assessment of
PROs
NIH Roadmap, 2003
$100 million invested to date
• Develop unified/integrated of multiple indicators
(cognitive, emotional, motor, sensory) of neural and
behavioral health functioning for use in large cohort
studies and clinical trials
• Could be used as a form of “common currency” across
diverse study designs and populations
• Would maximize yield from large, expensive studies with
minimal increment in subject burden and cost
NIH Neuroscience Blueprint, 2006
$40 million invested to date
Clinician/researchers wanted measures
which were:
Psychometrically sound
Brief, easy to use
Intellectual Property “Free”
Applicable in variety of settings
and with different subgroups
Available in multiple languages
As well as measures which:
Cover the full range of a trait
No Floor Effect
No Ceiling Effect
Available for use across the age span
Further, all of the NIH Systems Drive
to Utilize a Common Metric
The same instrument used for many diseases
The same “scale” applicable to all
instruments/diseases
The same scale regardless of instrument format:
Single item
Short Form
Long Form
Computerized Adaptive Test (CAT)
BUT most legacy measures failed to
make the grade:
Psychometrically sound NOT ALWAYS
Brief, easy to use RARELY
Intellectual Property “Free” NOT ALWAYS
Applicable in variety of settings SOMETIMES
and with different subgroups RARELY
Available in multiple languages SOMETIMES,
(and if so, rarely with the same meaning!)
Neither can most legacy measures:
Cover the full range of a trait ALMOST NEVER
No Floor Effect SOMETIMES
No Ceiling Effect NEVER?
Available for use across the age span RARELY
Nor do legacy instruments have:
The same instrument used for many diseases RARELY
The same “scale” applicable to all instruments/diseases
NEVER
The same scale regardless of instrument format: NOPE!
Single item
Short Form
Long Form
Computerized Adaptive Test (CAT)
More on the ceiling issue
Legacy measures can fail to identify treatment success, nor do
they typically accurately assess anyone above the mean!
It is impractical to use disease
specific instruments
And often patients don’t want to settle
for “average”function
Previously physically active patients, who are now recovering
from an accident, don’t want to be considered “cured”
because the instrument used to assess their physical
functioning “ceilings” at the 50% ile
Athletes and others in physically active roles need to
accurately differentiate very high levels of functioning
A cancer patient whose fatigue instrument shows them to be
“above” the clinically relevant range assessed by a typical
instrument– may be far away from from feeling “normal.”

NIH Measures can also be
compared to legacy measures
A common problem when using a variety of patient-reported
outcome measures is the comparability of scales on which the
outcomes are reported. Linking establishes relationships between
scores on two different measures.
The PRO Rosetta Stone (PROsetta Stone®) developed and
applied methods to PROMIS and other PCORR instruments
with other related instruments (e.g., SF-36, Brief Pain Inventory,
CES-D, MASQ, FACIT-Fatigue) to expand the range of PRO
assessment options within a common, standardized metric. It
provides equivalent scores for different scales that measure the
same health outcome.

Many of these measures already
ARE being used in EHR’s
2012 – EPIC enables PROMIS short forms
2014 – EPIC in the process of enabling PROMIS CATs
2014 – The Department of Defense EHR using CATs
Now: Walter Reed
Spring: Balboa and Madigan
Do we have time for more
examples?
