The table below documents every scale currently implemented in PsyScale — including its scoring method, reference period, and the interpretation thresholds used in the app. These thresholds are sourced from original validation studies or widely-cited clinical conventions; when ambiguity exists, the most conservative or commonly adopted cutoff is applied and annotated in the Notes column.
If you spot an error in a threshold, a scoring rule, or any other detail — or if a newer validation study establishes cutoffs with improved sensitivity and specificity — please reach out. The goal is for this reference to stay accurate and up to date.

Building
PsyScale is built on a strict privacy-by-design architecture. No user data is collected, transmitted, or processed by the developer at any point.
All information entered into the application — including patient identifiers, assessment responses, computed scores, and clinical notes — is stored exclusively on the user's local device. If the user has enabled iCloud Drive, this data may additionally be synchronized across the user's own Apple devices via their personal iCloud account, to which the developer has no access.
PsyScale does not integrate any third-party analytics frameworks, advertising networks, crash-reporting SDKs, or tracking technologies of any kind. The application does not establish any outbound network connections. No personally identifiable information, device identifiers, or health-related data is ever shared with the developer or any third party.
The application is fully functional in the absence of an internet connection and requires no account creation or registration.
Users retain complete and exclusive ownership of all data generated within the application. The developer holds no copy of any user data and is therefore unable to fulfill deletion requests on the user's behalf.
On Mac, data can be deleted by navigating to ~/Library/Application Support/ and deleting the Folder ‘PsyScale’.
On Windows, data can be deleted by navigating to (under construction) and deleting the Folder ‘PsyScale’.
Users are solely responsible for ensuring that data deletion complies with any applicable legal, professional, or institutional obligations prior to initiating deletion.
The scoring algorithms implemented in PsyScale are based on validated psychometric instruments published in peer-reviewed literature and widely adopted in clinical psychiatry and psychology. All scales are implemented in strict accordance with their original scoring instructions, including item weighting, subscale computation, and threshold interpretation as specified in the primary validation studies.
Where multiple threshold conventions exist in the literature, the most conservative or most widely cited cutoff is applied. Deviations from original scoring procedures, when present, are documented in the Methodology section of this website along with supporting references.
Full bibliographic citations for all instruments are provided in the Citations section. Users are encouraged to consult the original publications to verify implementation accuracy and to report any discrepancy via the Contact section.
PsyScale is a clinical decision-support tool intended exclusively for use by qualified healthcare professionals, including licensed physicians, psychiatrists, psychologists, and other credentialed practitioners operating within the scope of their professional authorization. It is not intended for use by, or directed at, patients or the general public.
The scores and interpretations generated by the application are derived from standardized psychometric instruments and are provided strictly for informational and reference purposes. They do not constitute a diagnosis, a clinical recommendation, or a substitute for professional clinical judgment. The interpretation of any score, and any resulting clinical decision, is the exclusive responsibility of the qualified clinician using the application.
The developer of PsyScale expressly disclaims all liability for any clinical act, omission, decision, or outcome — including but not limited to misdiagnosis, improper treatment, or patient harm — arising from, or in connection with, the use of this application. The developer does not supervise, endorse, or assume responsibility for the professional conduct of any individual who uses PsyScale, and accepts no liability for how assessment results are interpreted or acted upon in a clinical context.
By using PsyScale, the user acknowledges and accepts that clinical responsibility for patient care rests solely and entirely with the treating practitioner, and that the developer bears no responsibility of any kind for clinical outcomes.
