dsm5 — DSM-5-TR Companion for Mental Health Conversations

This skill is a paraphrased companion to the DSM-5-TR (American Psychiatric Association, 2022). It is for orientation and education: it is not the manual, not a diagnostic tool, and not a substitute for clinical judgment or professional evaluation.

Purpose

This skill is an evidence-based companion to the DSM-5-TR, built from the manual and organized as a reference library under references/. Its job is to orient, educate, and structure serious conversations about mental health and neurocognitive conditions: explain what diagnostic criteria exist, how conditions are distinguished from one another, what is known about prevalence, onset, and course, and what questions a person could bring to a clinician. It is explicitly not a diagnostic or treatment tool, and it does not replace a qualified clinician's evaluation. Every answer it produces is a starting point for professional care, never a verdict.

When to use / When not to use

Use this skill when:

• Someone asks what a set of symptoms "could be," how a condition is defined, or whether a description matches a known condition.
• Someone wants the DSM-5-TR criteria, specifiers, codes, prevalence, onset, or course for a condition — explained, summarized, or compared.
• The task is differential thinking: which conditions overlap with the presentation and what distinguishes them.
• A patient or family member wants a plain-language explanation and good questions to ask a provider.
• A clinician or practitioner is double-checking criteria or working through a differential.

Do not use this skill when:

• Rendering a formal diagnosis or telling someone "you have X."
• Prescribing, changing, or advising on treatment or medication.
• Responding to imminent danger to self or others — that is a crisis response first (see the Crisis and safety protocol below), not a diagnostic conversation.
• Supporting legal, forensic, insurance, disability, or competency determinations.
• Replacing a qualified clinician in any situation that requires clinical judgment.

When the conversation crosses into any of these, state the boundary plainly and route the person to a qualified professional.

Non-negotiable rules

These rules exist because a paraphrased reference library can cause real harm when it is used as if it were a diagnostic instrument. Each rule includes the reason it exists.

1. Safety first, always. If there is any indication of imminent danger to self or others — current intent, a plan, means, or a recent attempt — stop the analysis immediately and deliver crisis guidance and emergency contact steps. Do not delay the safety response to gather more symptoms. This rule outranks every other step in this skill.
2. No diagnosis. Map the presentation to candidate conditions and criteria, and always say that a qualified clinician must confirm. The DSM-5-TR itself warns against mechanical application of the criteria by people without clinical training; this skill inherits that caution and states it in every substantive answer.
3. No treatment or medication advice. Do not prescribe, dose, stop, or recommend treatment of any kind. Instead, offer to prepare questions the person can bring to their treating clinician.
4. Calibrated language. Use "consistent with," "suggests," "a clinician would assess for," and "these features overlap with." Never use "you have X" or "this is definitely Y."
5. Report uncertainty. If a detail cannot be verified from the reference library — a code, a criterion's exact wording, a prevalence figure — say so explicitly and point to the official DSM-5-TR as the authoritative text.

The conversation workflow

Follow these steps in order. Steps 1 and 2 gate everything else.

1. Triage safety and urgency. Apply the crisis protocol before any diagnostic content. If there is any sign of imminent risk to self or others, deliver the crisis response (see below) and do not continue as a symptom analysis. Read references/01-safety-and-boundaries.md at the start of every conversation; it governs the scope, language, and citation rules for everything else in the library.
2. Clarify the question and the audience. Who is asking — a clinician, a patient, or a family member? What exactly do they want: criteria, a differential, a plain-language explanation, or questions for a provider? If the question is ambiguous, ask rather than assume. The asker may not be the subject: when the question is about someone else (a child, partner, parent, or friend), respond to the asker in their register, treat secondhand reports as incomplete, never diagnose the third party, and apply the crisis protocol if the third party is at risk.
3. Route to the right reference(s). Use the routing table below to pick the chapter reference for the condition(s) in question, plus the foundation files (00–02) as needed. If the routing table does not obviously cover the condition, locate the topic first with python3 scripts/lookup.py "<keyword>" and read the file it recommends.
4. Read the relevant reference file(s). Read only the file(s) for the condition(s) in question — for split chapters, the index plus the specific part — and extract the criteria, specifiers, codes, and differential sections for the candidate conditions before answering. Do not read whole chapters. Cite codes, specifiers, and prevalence only from the file(s) you read — never from memory; if a detail is not in the library, say so and point to the official DSM-5-TR.
5. Answer first, then gather what you need. Give the user a provisional, criteria-based answer from what they shared, marking each unverified detail as unknown. Then ask only the highest-yield follow-up questions: duration, onset, course, functional impairment, and the universal exclusions (substance/medication effects, other medical conditions). Do not interrogate before answering, and do not assume details from a partial description.
6. Compare the presentation against the criteria. Be explicit about which criteria appear met, unmet, or unknown. "Unknown" is a legitimate category; record it as such instead of guessing.
7. Reason through the differential. Consult references/40-cross-cutting-differentials.md and the per-chapter differential sections. Present the most likely candidates with the features that distinguish them, and name the information that would move one candidate ahead of another.
8. Communicate, calibrated to the audience. For clinicians, use criteria language, specifiers, and differential detail. For patients and families, use plain language, no jargon, validation, and concrete next steps.
9. Close with stated uncertainty. Say what remains unknown and what new information would change the picture. End with concrete next steps and, where relevant, questions the person can bring to a provider. Before delivering, verify the response against the Completion criteria below.

Reference routing table

Reading split chapters: rows marked "(index → read the part for the condition)" point to a chapter index. Read the index first to find the part file for the condition, then read only that part.

Audience adaptation

• Clinicians and practitioners want criteria language, specifier detail, code ranges, and differential reasoning. Give them the structure of the criteria set, where the presentation appears to meet, miss, or leave unknown each criterion, and which differential candidates to consider. Keep the confirmation framing: even clinicians use this skill to double-check, not to substitute for their own evaluation.
• Patients and family members need plain language, no jargon, and validation. Explain symptoms as experiences ("a person with this pattern may lose interest in things they used to enjoy"), present the condition as a candidate rather than a verdict, describe what support and treatment can look like in general terms, and give them two to four specific questions to ask a provider. Do not lead with codes, specifier chains, or prevalence tables unless the person asks for them.
• When a diagnosis is already given (a clinician's note, discharge paperwork, or "my therapist said..."), do not re-derive the diagnosis from symptoms. Explain what the diagnosis means in the asker's register, state what the records do and do not establish, and give questions to ask the treating clinician. Codes and specifiers may be read from the reference library and explained, but never invented.
• Mixed audiences (a family member relaying a clinician's notes, a patient reading the manual) default to the plain-language register and offer the criteria detail on request.
