Mental health screening instrument rights guide
A practical rights-status map for the 27 instrument routes reviewed by MindCheck Tools. It separates public-use evidence from noncommercial limits, permission gates and public-administration blocks.
Evidence last reviewed: August 5, 2026. Terms can change; recheck the linked owner source before each release.
Public-use basis found

Read the UNSW DASS FAQ sourceA safer implementation sequence
- Identify the exact version, owner, publisher and intended audience.
- Archive the current owner-controlled terms and record whether the contemplated use is public, electronic and commercial.
- Obtain written permission or a licence when the authoritative source requires it.
- Independently verify content parity, scoring, result wording, safety, privacy and accessibility.
- Record qualified reviewer scope and release evidence before publication.
Frequently asked questions
Does a public questionnaire automatically mean it is free to reuse?
No. Public access is not a reuse licence. The owner may limit electronic administration, commercial use, modification, scoring, or public result delivery.
Does this guide grant permission to use an instrument?
No. This is an evidence register, not legal advice or a licence. Only the owner or an authorized publisher can grant permission.
Does rights clearance make a public mental-health assessment safe to launch?
No. Exact-version and scoring review, non-diagnostic result language, crisis safeguards, privacy, accessibility, and appropriately qualified review remain separate release gates.
Need an implementation evidence review?
MindCheck Tools can organize public or fictional-staging evidence without receiving patient records, assessment answers, scores, diagnoses or other health information.
