Following one person over time
This measure exists to answer one question the 14 September briefing asked: does a person
move from acute distress towards a clinical disorder, or away from it? It is for repeating with
someone already in care, so the second score can be compared with the first.
Do not use this to screen a shelter. In the Nepali validation the cut-off of 10 or more had a
positive predictive value of 0.42 — in that primary-care sample, fewer than half of the people who
screened positive turned out to have a depressive episode. Run it across a displaced population and
most positives will be wrong, while the people you flag will have been told something about themselves
that is not true. Use it where someone has already been identified and referred.
The Nepali text is missing, and this form is not ready for field use without it. The Nepali
version validated by the PRIME consortium exists, but the copy available is typeset in a legacy
non-Unicode Nepali font, so the characters cannot be transferred here without risking a corrupted
questionnaire. Nothing has been translated or approximated. Before any real use, obtain the
Unicode Nepali items from the PRIME / Kohrt source and have them checked by a Nepali-speaking
clinician. Administering the English items to a Nepali speaker through an untrained interpreter is
not the same instrument and the cut-off does not carry over.
Attribution
PHQ-9 was developed by Drs Robert L. Spitzer, Janet B.W. Williams, Kurt Kroenke and colleagues, with
an educational grant from Pfizer Inc. The instrument carries the statement: “No permission required
to reproduce, translate, display or distribute.” The items above are reproduced verbatim on that
basis. The Nepali adaptation was made and validated through the Programme for Improving Mental Health
Care (PRIME) consortium, funded by UK aid — and is not included here, for the reason given at
the top of this page.
