QS-20
Fact Sheet
Short Description
The Shedler QS-20 is a 20-question mental health test
designed for use in medical settings. It screens for anxiety
and depression and also screens for suicide risk. The
test is self-administered by patients in a minute or two.
Physicians receive a chart-ready, computer-generated test
report, printed immediately, on-site. QS-20 is an acronym
for “Quick Screen-20.”
When to administer this assessment
The Shedler QS-20 may be administered to all new or established
patients to screen for depression and anxiety. It may
be readministered as often as desired to monitor patient
status or assess treatment outcome.
Detailed Assessment description
Patients self-administer the Shedler QS-20 using hand-held
computer tablets. Diagnostic questions are displayed on
a video screen and patients answer by pressing True and
False response buttons. The test is well accepted by medical
patients.
Physicians receive a chart-ready diagnostic report that
includes depression and anxiety scores, plus a global
severity index indicating overall level of mental distress.
Standard scores (T-scores) and percentiles are displayed
in bar graph format, so the physician can see instantly
where the patient stands in the population. Scores above
the 84th percentile are flagged. The report also provides
a list of the symptoms reported by the patient to guide
further inquiry and treatment decisions.
The Shedler QS-20 is reliable and valid. The depression
and anxiety scales correlate highly (.91 and .90, respectively)
with the full QPD Panel Depression and Anxiety severity
indexes.
