Methodology

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.

MAST	Michigan Alcoholism Screening Test	Question 7 always scores 0 regardless of the answer. This item was removed in a later 24-item version of the scale.
MDI	Major Depression Inventory	Increased and decreased appetite have been merged, as well as increased and decreased activity: when separate, the highest score is the one retained in the test.

Legal, Privacy & Regulatory Information

I. Nature and Purpose of PsyScale

PsyScale is a digital tool that faithfully reproduces established, peer-reviewed psychiatric rating scales and questionnaires. It does not create, modify, or reinterpret any clinical instrument. It functions solely as a distributor and digital interface for instruments that are already published, validated, and freely used in clinical practice worldwide.

PsyScale computes scores strictly according to the original scoring instructions specified in the primary validation studies. Where multiple scoring conventions exist in the literature, PsyScale applies the most conservative or most widely cited cutoff and documents the choice in the Methodology section.

PsyScale does not generate diagnoses, clinical recommendations, treatment suggestions, or prognoses. It does not apply any proprietary algorithm, artificial intelligence, machine learning, or statistical model to the data entered by the user. It is a calculator and a presentation layer — nothing more.

II. Regulatory Status — Not a Medical Device

PsyScale is not a medical device. It has not been certified, cleared, or approved under any medical device regulatory framework, including but not limited to:

European Union: PsyScale does not bear the CE marking and has not been evaluated or certified under Regulation (EU) 2017/745 (Medical Device Regulation — MDR) or any prior directive.
United States: PsyScale has not been cleared or approved by the U.S. Food and Drug Administration (FDA) under Section 510(k), the De Novo pathway, or any Premarket Approval (PMA) process. It is not listed as a registered medical device with the FDA.
Other jurisdictions: PsyScale has not received regulatory clearance or approval from any national or regional health authority worldwide.

PsyScale is not intended to diagnose, treat, cure, mitigate, or prevent any disease or medical condition. It is not intended to replace, supplement, or override the professional judgment of any qualified healthcare provider.

Users should not rely on PsyScale as a medical device, and should not make any clinical, therapeutic, or diagnostic decision based solely on PsyScale output without independent clinical assessment.

III. Medical Disclaimer and Limitation of Liability

PsyScale is intended for use as a clinical support tool by qualified healthcare professionals — including licensed physicians, psychiatrists, psychologists, and other credentialed practitioners operating within the scope of their professional authorization. It may also be used by individuals for informational and self-screening purposes; however, no self-assessment using PsyScale should be considered a substitute for a professional evaluation.

The scores and severity interpretations displayed by the application are derived from standardized psychometric instruments and are provided strictly for informational and reference purposes. They do not constitute a medical opinion, a diagnosis, a clinical recommendation, or a prescription.

Neither Liminal Pictures, nor its founder, nor any contributor to the development or maintenance of PsyScale, shall be held liable — under any legal theory (contract, tort, strict liability, negligence, or otherwise) — for any direct, indirect, incidental, consequential, special, exemplary, or punitive damages arising from or in connection with:

The use or inability to use PsyScale;
Any clinical decision, act, or omission made in reliance on PsyScale output;
Any misdiagnosis, delayed diagnosis, inappropriate treatment, or adverse patient outcome;
Any interpretation of scale results by any user, whether professional or non-professional;
Any technical malfunction, data loss, scoring error, or software defect;
Any unauthorized access to, or misuse of, patient data stored on the user's device.

By using PsyScale, the user expressly acknowledges that all clinical responsibility for patient care rests solely and entirely with the treating practitioner, and that neither Liminal Pictures nor its founder assumes any duty of care toward any patient or end-user.

IV. Professional Use and Patient Safety

Healthcare professionals using PsyScale in a clinical context are solely responsible for:

Selecting the appropriate rating scale for the patient's clinical presentation;
Ensuring the selected scale is validated for the patient's population, age group, and clinical context;
Interpreting scores within the broader clinical picture, taking into account comorbidities, medication effects, cultural context, and patient history;
Complying with all applicable professional, ethical, and legal obligations governing their practice;
Safeguarding any patient data entered into PsyScale in accordance with applicable data protection laws (including but not limited to the EU General Data Protection Regulation, HIPAA, and local healthcare data regulations).

PsyScale is not a substitute for clinical training, clinical supervision, or continuing professional education.

Support

Getting started

Tap the + button to log an event. You can select as many events as you like — only the ones you've chosen to track will appear in the list.

Mood

If you chose to track your mood, a colored bar appears on the home screen. Tap it to log a score on a scale of 0 to 10. You can log mood multiple times in a day — each entry is timestamped and listed separately. Tap any mood entry to expand it and edit its time or add a note. The daily average is shown in the mood bar summary.

Events

Each logged event appears as a row under the selected day. Tap an entry to expand it: you can set a start time, an end time, and add a short note. The same event can be logged more than once on the same day. To delete an entry, expand it and tap the trash icon.

Calendar view

The calendar shows a colored dot for each day that has data. Swipe left or right between months. Tap any day to see its entries below, or to log new ones.

Statistics

Tap the chart icon to explore your data. Switch between Events and Mood views, and use the period selector (Week, Month, Year, All) to change the time range. Swipe left or right to navigate between periods. The Events view shows a heatmap — one row per event, one column per time unit. A filled cell means the event occurred; a number inside means it occurred more than once that day. The Mood view shows a chart of your average mood over time on a fixed 0–10 scale.

Managing events

Go to Settings → Manage events to add, remove, or reorder the events you track. You can also add medications (with a custom name) and free-text custom events.

Reminders

Go to Settings → Reminders to enable daily notifications prompting you to log your mood. You can set up to five reminders at different times of day. Reminders can be turned on or off at any time.

Exporting your data

Go to Settings → Export data to download your history as a CSV or as a PDF report. The PDF includes a mood chart and an event heatmap. You can choose the time period and which events to include.

Watch app

If you have an Apple Watch, Mu. lets you log events and your mood directly from your wrist. Data syncs automatically with your iPhone.

Watch complications

Three complication styles are available: a circular one showing today's event count and mood, and two rectangular ones — one for the mood bar, one for the last event logged today.
