Corrections and verifications
Every correction to a published record is logged here with the old value, the new value, and the source that settled it. This page is trust infrastructure: the registry expects to be wrong sometimes and corrects itself in public, newest first.
Corrections
C-0003 · Patient Health Questionnaire-9 (PHQ-9)
PHQ-9 licence wording precision: pass one described the status as 'public domain'. The steward terms grant a copyright exemption and free use rather than asserting a formal public-domain dedication.
Was: Free / public domain. Pfizer released the PHQ and GAD-7 without copyright restriction.
Now: Free for download and use; content on the PHQ Screeners site is 'expressly exempted from Pfizer's general copyright restrictions'. No permission or fee required, attribution to Kroenke et al 2001 expected. This is a free-use copyright exemption, not a formally asserted public-domain status.
C-0002 · Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS) and Short Warwick-Edinburgh Mental Wellbeing Scale (SWEMWBS)
WEMWBS licence-currency update: pass one implied NHS/non-profit users obtain a no-fee non-commercial licence. Warwick Innovations introduced charges for NHS organisations from 1 December 2024.
Was: Academic and non-profit users obtain a no-fee non-commercial licence; commercial users pay a tiered fee.
Now: Registration still required; non-commercial and commercial licences separated. From 1 December 2024, charges apply to NHS organisations (NHS trusts, GP surgeries and NHS-funded bodies) on a published tiered scale (e.g. up to 30 participants GBP 45, up to 100 GBP 125, up to 1000 GBP 600). Non-NHS academic/non-profit non-commercial registration remains available; commercial users pay fees. Verify current tier with Warwick Innovations before fielding.
C-0001 · WHO-5 Well-Being Index
WHO-5 licence mis-stated in pass one by trusting 2015/2020 review literature and missing WHO's October 2024 republication of the WHO-5 master version under a formal Creative Commons licence.
Was: Free to use; distributed at no charge, no licence fee or royalty; may be reproduced and translated with acknowledgement of source (free availability sourced to Topp 2015 / Lara-Cabrera 2020 review literature). No formal open licence stated.
Now: Copyright World Health Organization 2024; the WHO-5 master version is available under the Creative Commons Attribution-NonCommercial-ShareAlike 3.0 IGO licence (CC BY-NC-SA 3.0 IGO). Document ref WHO/UCN/MSD/MHE/2024.1. Non-commercial use and adaptation permitted with attribution and share-alike; commercial (including employer/vendor) use requires WHO permission.

V-0001 · Turnover Intention Scale-6 (TIS-6, Roodt)
Licence verified at steward journal page (CC BY 4.0); performed at ingest by the maintaining thread, upgrading the pass-two not-verified flag. Field: identity.licence_status
Dataset changes
Dataset 0.2.1
ONS-4 item split per schema v0.2 rule 4: added four first-class item records (ons-4-life-satisfaction, ons-4-worthwhile, ons-4-happiness, ons-4-anxiety) with parent_id ons-4; parent gains an items list. Graded evidence remains at set level (item properties reference the parent with evidence_form 'parent'; internal consistency and structural validity are Not-applicable at item level). Item records carry question_bank_ref so the registry and the question bank share one canonical per-item description. The 27-row grade matrix is unchanged; item records are children, not matrix rows.
