FREE PMHNP Study Guide 2026: A Complete, ANCC-Aligned Walkthrough

This free PMHNP study guide walks through everything the ANCC PMHNP-BC exam tests, organized into the same five content domains ANCC uses to build the exam from its current Test Content Outline.^[1] It teaches at advanced-practice depth — diagnosis, prescribing, monitoring, and the law of psychiatric care.

It is interactive, not a wall of text: every domain has worked clinical scenarios, psychopharmacology and monitoring tables, labeled diagrams, and built-in flashcards, so you learn by doing. Because this is a high-stakes psychopharmacology exam, every clinical fact here is cited to a primary source — ANCC, DSM-5-TR, and FDA/DailyMed drug labels.

Read it domain by domain, then round out your prep with our practice test and flashcards. The PMHNP-BC certifies you to assess, diagnose, prescribe for, and provide psychotherapy to patients across the lifespan — from infants to frail elders.

PMHNP-BC Exam Snapshot

ANCC reports your result as a scaled score from 0 to 500 and you must reach 350 to pass; because the standard is criterion-referenced, there is no fixed passing percentage.^[3] The exam is weighted toward the work nurse practitioners actually do — the two largest domains, Advanced Practice Skills (27%) and a combined diagnosis-and-treatment block, are where most of your points live.^[1]

How the PMHNP-BC Exam Works & the Lifespan Lens

The PMHNP-BC is a fixed-length, 175-item, computer-based exam delivered over 3.5 hours; 150 items are scored and 25 are unscored pretest items that look identical to scored ones.^[1]

Every domain is also tagged across the lifespan — ANCC explicitly samples age groups from infant and preschool through adolescent, adult, older adult, and frail elderly — so expect pediatric questions (for example, the antidepressant suicidality boxed warning in those under 25, or stimulant growth monitoring) and geriatric questions (the Beers Criteria, “start low, go slow” dosing, and antipsychotic mortality risk in dementia).

Eligibility requires an active RN license, a master’s, post-graduate certificate, or DNP in the PMHNP role from a CCNE- or ACEN-accredited program, at least 500 faculty-supervised clinical hours, the three APRN core courses (advanced pathophysiology, health assessment, and pharmacology), and clinical training in at least two psychotherapy modalities.^[2] A second valid pathway — the AANPCB PMHNP-C, launched in April 2024 — tests the same scope with similar logistics, so this guide serves candidates for either exam while teaching to the ANCC outline as the canonical blueprint.

I · Scientific Foundation

Scientific Foundation is 22% of the exam — about 33 scored questions.^[1] It is the neuroscience and pharmacology that everything else rests on: how neurotransmitter systems map to symptoms and drug targets, how drugs are absorbed and metabolized, and how to recognize the dangerous movement and toxicity syndromes that psychotropics cause.

Neuroanatomy & Neurotransmitters

Learn the brain regions by the symptom they produce: the amygdala is the fear/threat detector (hyperactive in anxiety and PTSD); the hippocampus consolidates memory and shrinks with chronic cortisol in depression and PTSD; the prefrontal cortex runs executive function and impulse control and myelinates last, completing in the mid-20s — which is why adolescents are impulsive and why the antidepressant suicidality warning runs through age 24. The HPA axis (hypothalamus → pituitary → adrenal → cortisol) is chronically over-activated in depression and PTSD.

The single highest-yield diagram on this exam is the four dopamine pathways and what happens when an antipsychotic blocks D2 in each. Excess dopamine in the mesolimbic pathway drives positive psychotic symptoms (the therapeutic target), while a deficit in the mesocortical pathway drives negative and cognitive symptoms — so blocking D2 helps the first and can worsen the second.

The other transmitters map cleanly to drug classes:

• Serotonin (5-HT) — mood, anxiety, sleep — is raised by SSRIs, SNRIs, and MAOIs (effect is delayed 2–4+ weeks because it depends on downstream receptor adaptation, not the immediate reuptake block).
• Norepinephrine drives arousal and attention (SNRIs, TCAs, atomoxetine, stimulants).
• GABA is the main inhibitory transmitter and the target of benzodiazepines (positive allosteric modulators of GABA-A).
• Glutamate is the main excitatory transmitter, and NMDA hypofunction underlies the schizophrenia/ketamine model (esketamine treats resistant depression).
• Acetylcholine supports memory — its blockade causes the anticholinergic toxidrome and its deficit defines Alzheimer disease.

Pharmacokinetics, CYP450 & Pharmacodynamics

ADME — absorption, distribution, metabolism, excretion — is the frame. Lithium and gabapentin are renally cleared (lithium is handled like sodium, so dehydration and low salt raise its level); most other psychotropics are metabolized by hepatic CYP450 enzymes. Half-life sets dosing and steady state (roughly five half-lives) — fluoxetine is the outlier, with an active metabolite (norfluoxetine) lasting 1–2 weeks, so it self-tapers.

CYP450 interactions are heavily tested. The pattern: an inhibitor raises the level of a substrate (toxicity) and an inducer lowers it (failure).

On the pharmacodynamic side, know agonist versus antagonist and the off-target receptors that explain side effects: H1 blockade → sedation and weight gain, M1 (muscarinic) blockade → the anticholinergic toxidrome, and α1 blockade → orthostatic hypotension. Aripiprazole is a D2 partial agonist— a “dopamine stabilizer” with low prolactin and metabolic burden.

EPS, NMS & Serotonin Syndrome

Extrapyramidal symptoms come from D2 blockade in the nigrostriatal pathway, and the exam tests them by timing: acute dystonia within hours–days (treat with IM/IV benztropine; laryngospasm is an airway emergency); akathisia within days–weeks (reduce dose or add propranolol — and take it seriously, as it is linked to suicidality); drug-induced parkinsonism within days–weeks; and tardive dyskinesia after months–years (often irreversible — screen with the AIMS, treat with a VMAT2 inhibitor, and never give an anticholinergic, which worsens it).

The two killer drug reactions are constantly confused, so learn them side by side. Neuroleptic malignant syndrome is a slow (days), hypodopaminergic reaction to antipsychotics with lead-pipe rigidity, bradyreflexia, very high fever, and elevated CK. Serotonin syndrome is a fast (hours) hyperserotonergic reaction with clonus and hyperreflexia.

Psychogenomics & Neurodevelopment

Pharmacogenomics explains why standard doses fail or harm: a CYP2D6 poor metabolizer gets toxic levels of a 2D6 substrate at a normal dose, while an ultrarapid metabolizer gets subtherapeutic levels and treatment failure (and over-converts codeine/tramadol to dangerous opioid levels). Screen HLA-B*1502 before carbamazepine or oxcarbazepine in patients of Asian ancestry to prevent Stevens-Johnson syndrome. The major psychiatric disorders are highly heritable — schizophrenia and bipolar disorder roughly 60–85%, ADHD around 70–80%, and MDD around 35–40%.

II · Advanced Practice Skills

Advanced Practice Skills is the largest domain — 27%, about 41 scored questions.^[1] It is the clinician’s craft: how you interview, which screening tool you choose and how you read it, the mental status exam, and how you assess risk and manage an emergency.

Clinical Interviewing & Motivational Interviewing

Open with open-ended questionsfor narrative, then funnel to closed-ended questions for specific facts and safety screening. Use reflection, clarification, summarization, silence, and validation; avoid leading questions and “why” questions.

Motivational interviewing is a collaborative method to resolve ambivalence — its spirit is partnership, acceptance, compassion, and evocation, and its skills are OARS(open questions, affirmations, reflective listening, summaries). You evoke “change talk,” roll with resistance, and resist the “righting reflex” of arguing the patient into change — matching your approach to the patient’s stage of change.

Screening Tools & Interpretation

ANCC expects you to select and interpret the right instrument. Memorize the cutoffs — the PHQ-9 and GAD-7 each cross into clinically significant territory at a score of 10, the CIWA-Ar drives symptom-triggered alcohol- withdrawal dosing, and the COWS tells you when it is safe to induct buprenorphine.

The Mental Status Exam

The mental status exam is the psychiatric counterpart of the physical exam. The distinction the exam loves: moodis the patient’s stated, sustained emotion (subjective, often quoted), while affect is what you observe (objective — its range, from full to flat, and its congruence with mood).

Thought process is the form of thinking (circumstantial reaches the point eventually; tangential never returns; flight of ideas suggests mania), and thought content is what the patient thinks (delusions, obsessions, suicidal or homicidal ideation). Auditory hallucinations are most common in primary psychiatric illness, whereas visual or tactile hallucinations point toward a medical or substance cause.

Risk Assessment & Psychiatric Emergencies

Ask directly about suicide — it does not plant the idea. The strongest predictor of future suicide is a prior attempt; other acute factors are a plan with available means, hopelessness, command hallucinations, agitation, substance use, and recent loss.

Distinguish chronic (baseline) from acute (state) risk, and remember that means restriction (firearms, medications) is one of the most evidence-based interventions. Note two traps: the SAD PERSONSmnemonic is a teaching aid, not a validated triage tool, and a sudden lift in a depressed patient’s mood can mean they have decided to act — increase, do not relax, vigilance.

In an agitation emergency, verbal de-escalation comes first — reduce stimulation, keep a safe distance with an exit for both of you, offer choices, and use medication or restraint only when de-escalation fails, always choosing the least restrictive option. A collaborative safety plan(the Stanley-Brown format — warning signs, coping strategies, supports, professionals, means restriction) replaces the outdated, non-evidence-based “no-suicide contract.”

III · Diagnosis and Treatment

Diagnosis and Treatment is 22% of the exam — about 33 scored questions — and, combined with the science in Domain I, it is the psychopharmacology heart of the test.^[1] This is the highest-stakes content on the exam: a wrong dose, level, or warning can harm a patient, so every figure below is cited to DSM-5-TR or the FDA drug label.

DSM-5-TR Diagnostic Criteria

Know the criteria that separate look-alike diagnoses. DSM-5-TR defines major depressive disorder as five or more symptoms for at least two weeks including depressed mood or anhedonia (SIGECAPS), and bipolar I by a single manic episode (≥1 week or hospitalization) — so always screen for past mania before prescribing an antidepressant.^[4] For the psychotic disorders, duration is the discriminator: brief psychotic disorder lasts under a month, schizophreniform 1–6 months, and schizophrenia at least six months.

Antidepressants

All antidepressant classes share one boxed warning — increased suicidality in patients under 25 — so monitor closely early and at dose changes.^[6] SSRIs are first-line; SNRIs add norepinephrine (watch blood pressure with venlafaxine); bupropion avoids sexual side effects but lowers the seizure threshold (max 450 mg/day; contraindicated in eating and seizure disorders); and MAOIs and TCAs are reserved.

Two label facts recur: citalopram is dose-capped at 40 mg/day (20 mg in patients over 60) for QTc safety, and short-half-life agents (paroxetine, venlafaxine) cause the worst discontinuation symptoms — taper them.

Mood Stabilizers

Lithium is the gold standard for bipolar I and is the one psychotropic that reduces suicide risk — but its therapeutic index is narrow. Per the FDA label, the therapeutic range is 0.8–1.2 mEq/L for acute mania and 0.8–1.0 mEq/L for maintenance, drawn as a 12-hour trough, with toxicity at or above 1.5 mEq/L (the commonly taught lower bound of 0.6 comes from secondary literature, not the label).^[5] Lamotrigine covers the depressive pole but carries a boxed warning for serious rash and must be titrated slowly — especially with valproate, which doubles its level.

Antipsychotics

First-generation (typical) antipsychotics are potent D2 blockers with more EPS and prolactin elevation; second-generation (atypical) agents add 5-HT2A antagonism for fewer EPS but more metabolic side effects — so check weight, fasting glucose, and lipids at baseline and periodically. Every antipsychotic carries the boxed warning for increased mortality in elderly patients with dementia-related psychosis.^[5]

Clozapine is the most effective drug for treatment-resistant schizophrenia and the only one shown to reduce suicidality, but it carries boxed warnings for severe neutropenia, seizures, myocarditis, orthostatic hypotension, and GI hypomotility.

Absolute neutrophil count monitoring continues on the label schedule (weekly for six months, then less often; hold below 1,000/µL in the general population) — and note the 2026 update: the FDA removed the formal Clozapine REMS in 2025, so prescribers no longer enroll or report an ANC before each dispense, although the monitoring itself is still recommended.^[5] If a question references the “Clozapine REMS,” answer to the version it is keyed to.

ADHD, Anxiolytics & Addiction Medicine

Stimulants are first-line for ADHD (Schedule II; monitor cardiovascular status and growth); only atomoxetine, among the non-stimulants, carries a boxed warning (suicidal ideation in youth) — guanfacine and clonidine do not. Benzodiazepines are short-term anxiolytics with dependence and withdrawal risk (taper to stop — abrupt cessation can cause seizures), while buspirone is a non-dependence-forming alternative that takes 2–4 weeks and is not used as needed.

In addiction medicine, know the medications for use disorders: naltrexone (for alcohol and opioid use disorder — be opioid-free 7–10 days first; note that oral naltrexone no longer carries a boxed warning, with hepatotoxicity now a Warnings-section caution), acamprosate (renally cleared craving reduction), disulfiram (aversive reaction with alcohol), buprenorphine and methadone for opioid use disorder, and naloxone to reverse overdose.^[5]

IV · Psychotherapy & Related Theories

Psychotherapy and Related Theories is 11% of the exam — about 17 scored questions.^[1] It is the smallest domain but a reliable source of points if you know which modality fits which problem and which theorist owns which framework.

Psychotherapy Modalities

CBT (Aaron Beck) identifies and restructures cognitive distortions and uses behavioral activation — it is first-line for depression and most anxiety disorders, and exposure with response prevention (a behavioral CBT technique) is the gold standard for OCD. DBT (Marsha Linehan) is the gold standard for borderline personality disorder and self-harm, built on four modules — mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness.

Interpersonal therapy targets grief, role transitions, role disputes, and interpersonal deficits; person-centered therapy (Rogers) rests on unconditional positive regard, empathy, and congruence; and psychodynamic therapy works with transference (the patient’s feelings redirected onto the therapist) and countertransference (the therapist’s reactions toward the patient).

Change & Developmental Theories

The transtheoretical model (Prochaska and DiClemente) moves through precontemplation, contemplation, preparation, action, and maintenance, with relapse possible — and the exam tests matchingthe intervention to the stage (consciousness-raising in precontemplation, planning in preparation, relapse prevention in maintenance). Lewin’s model is unfreeze → change → refreeze. Among developmental theorists, Erikson’s eight psychosocial stages and Piaget’s four cognitive stages are the most heavily tested.

Therapeutic Alliance & Family Theories

The therapeutic alliance — the bond, shared goals, and agreed tasks between clinician and patient — is the single strongest predictor of psychotherapy outcome. Maintaining it requires sound boundaries: a boundary crossing may be minor or even therapeutic, but a boundary violation (a sexual, financial, or exploitative dual relationship) is always harmful, and the clinician is always responsible.

Trauma-informed care (SAMHSA’s four R’s and six principles) frames the whole relationship.^[8] Among family theories, know structural therapy (Minuchin — boundaries, subsystems), Bowen (differentiation of self, triangulation), and narrative therapy (externalize the problem and re-author the story).

V · Ethics, Legal Principles & Cultural Care

Ethics, Legal Principles, and Cultural Care is 17% of the exam — about 26 scored questions.^[1] A useful heuristic runs through it: when duties conflict, a safety or legal mandate generally overrides confidentiality and autonomy — but only to the least extent necessary (least restrictive care, minimum necessary disclosure).

Consent, Capacity & Confidentiality

Informed consent is a process with four elements — capacity, disclosure of risks/benefits/alternatives, the patient’s understanding, and voluntariness. Distinguish capacity (a clinical, decision-specific determination the PMHNP makes, which can fluctuate) from competency (a global legal determination only a court makes) — a clinician never declares a patient “incompetent.” HIPAA permits using protected health information for treatment, payment, and operations without separate authorization, while 42 CFR Part 2 gives stricter protection to substance-use-disorder records.^[9]

Know the exceptions to confidentiality: the Tarasoff duty to protect identifiable third parties from a serious threat, mandatory reporting of child and elder abuse, danger to self, a court order, and reportable conditions.

Commitment, Ethics & Case Law

Civil commitment requires that a person, because of mental illness, be a danger to self, a danger to others, or gravely disabled — and clinicians must always use the least restrictive option. A commitment authorizes detention but not forced medication, which needs a separate emergency or judicial determination.

The four bioethical principles — autonomy, beneficence, nonmaleficence, and justice — structure ethical dilemmas, which usually pit autonomy against beneficence; when a patient is competent and not dangerous, autonomy prevails. Capacity itself is assessed on four prongs (communicate a choice, understand, appreciate, reason). A handful of landmark cases recur on the exam.

Cultural Care & Advocacy

Practice cultural humility— lifelong self-reflection rather than a finished “competence” — and use the DSM-5-TR Cultural Formulation Interview to understand a patient’s explanatory model. Address social determinants of mental health (housing, income, education, discrimination, access) and reduce barriers such as stigma, cost, and language — always using a qualified interpreter, never a family member.

Provide affirming care for LGBTQ+ patients (correct names and pronouns; being transgender is not a mental disorder). For advocacy and accommodations, distinguish IDEA (special-education IEPs) from Section 504 (accommodation plans), and know the ADA (reasonable workplace accommodations) and FMLA (up to 12 weeks of job-protected leave, including for mental health).^[10]

How to Use This Study Guide

Work through the guide one domain at a time. After each domain, check it off in the contents to raise your exam-readiness score, then drill the same content in our free practice test and flashcards — active recall and timed practice are what move knowledge into exam-day performance.

• Weight your time by the blueprint. Advanced Practice Skills (27%) and the combined diagnosis-and-treatment science carry the most points — start there.
• Master the psychopharmacology cold. This is a safety exam: lithium levels, black-box warnings, EPS, and the serotonin-syndrome-versus-NMS distinction recur constantly.
• Think across the lifespan. Expect pediatric (suicidality warning, stimulant growth) and geriatric (Beers Criteria, “start low, go slow”) angles on the same drug.
• Apply the nursing process. When asked what to do FIRST, assess — unless an immediate safety threat demands action first.
• Trust primary sources. When a remembered fact and an official source disagree (e.g., the lithium range), go with the FDA label and DSM-5-TR.

Common questions PMHNP candidates search and get asked — each answered briefly and backed by an official source (ANCC, DSM-5-TR, FDA/DailyMed, or NIH/NIMH/SAMHSA). Tap any card to test yourself.

PMHNP Glossary

Key PMHNP terms in one place. Hover any dotted term throughout the guide for its definition; the full list is below.

PMHNP-BC

Psychiatric-Mental Health Nurse Practitioner — Board Certified, the credential awarded by ANCC after passing the across-the-lifespan certification exam.

ANCC

American Nurses Credentialing Center — the ANA subsidiary that owns and scores the PMHNP-BC exam and writes the Test Content Outline.

DSM-5-TR

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (American Psychiatric Association) — the standard for psychiatric diagnosis.

EPS

Extrapyramidal symptoms — movement disorders (acute dystonia, akathisia, drug-induced parkinsonism, tardive dyskinesia) caused by dopamine D2 blockade in the nigrostriatal pathway.

tardive dyskinesia

Late-onset, often irreversible involuntary choreoathetoid movements (lip-smacking, tongue protrusion) from chronic D2 blockade; screened with the AIMS and treated with VMAT2 inhibitors — anticholinergics worsen it.

akathisia

A subjective sense of inner restlessness and inability to sit still; treated by lowering the dose, switching, or adding propranolol — and important because it is linked to suicidality.

acute dystonia

Sustained, painful muscle contractions (torticollis, oculogyric crisis, laryngospasm) occurring hours to days after an antipsychotic; treated urgently with IM/IV benztropine or diphenhydramine.

NMS

Neuroleptic malignant syndrome — a life-threatening reaction to dopamine blockade marked by hyperthermia, 'lead-pipe' rigidity, autonomic instability, altered mental status, and elevated CK; treated by stopping the drug plus dantrolene or bromocriptine.

serotonin syndrome

A potentially life-threatening result of serotonin excess marked by mental-status change, autonomic instability, and neuromuscular hyperactivity (clonus, hyperreflexia); rapid onset; treated by stopping serotonergic agents and giving cyproheptadine.

SSRI

Selective serotonin reuptake inhibitor (sertraline, escitalopram, fluoxetine) — first-line for depression and anxiety; blocks the serotonin transporter (SERT).

SNRI

Serotonin-norepinephrine reuptake inhibitor (venlafaxine, duloxetine, desvenlafaxine) — first-line; adds norepinephrine reuptake inhibition (useful for pain) and can raise blood pressure.

MAOI

Monoamine oxidase inhibitor (phenelzine, tranylcypromine) — a reserved antidepressant requiring a tyramine-free diet to prevent hypertensive crisis and washout periods to prevent serotonin syndrome.

TCA

Tricyclic antidepressant (amitriptyline, nortriptyline) — effective but anticholinergic, cardiotoxic (QRS widening), and lethal in overdose; now a second- or third-line option.

bupropion

An NDRI antidepressant and smoking-cessation aid with no sexual dysfunction or weight gain; it lowers the seizure threshold and is contraindicated in eating and seizure disorders.

lithium

A first-line bipolar mood stabilizer with a narrow therapeutic index — FDA range 0.8–1.2 mEq/L acute and 0.8–1.0 maintenance, toxicity at ≥1.5; requires renal and thyroid monitoring and is teratogenic (Ebstein anomaly).

lamotrigine

A mood stabilizer used for the depressive pole of bipolar disorder; it carries a boxed warning for serious rash (Stevens-Johnson syndrome) and must be titrated slowly, especially with valproate.

valproate

A mood stabilizer/anticonvulsant for acute mania; boxed warnings for hepatotoxicity, pancreatitis, and teratogenicity (neural-tube defects); monitor LFTs and platelets.

carbamazepine

A mood stabilizer/anticonvulsant; boxed warnings for SJS/TEN (screen HLA-B*1502) and agranulocytosis/aplastic anemia; it auto-induces its own metabolism over 3–5 weeks.

clozapine

The most effective antipsychotic for treatment-resistant schizophrenia; carries boxed warnings (severe neutropenia, seizures, myocarditis, orthostasis, GI hypomotility). The FDA removed the Clozapine REMS in 2025, but label-schedule ANC monitoring is still recommended.

atypical antipsychotic

A second-generation antipsychotic (risperidone, olanzapine, quetiapine, aripiprazole) that blocks D2 and 5-HT2A — fewer EPS than typicals but more metabolic side effects requiring weight, glucose, and lipid monitoring.

buspirone

A 5-HT1A partial-agonist anxiolytic for generalized anxiety — non-sedating and non-dependence-forming, but it takes 2–4 weeks to work and is not used as needed.

benzodiazepine

A GABA-A positive allosteric modulator used short-term for anxiety; carries dependence, tolerance, and withdrawal risk and a boxed warning when combined with opioids.

naltrexone

An opioid antagonist used for alcohol and opioid use disorder; patients must be opioid-free ~7–10 days first. Oral naltrexone no longer carries a boxed warning — hepatotoxicity is now a Warnings-section caution.

PHQ-9

A nine-item depression screen and severity measure (0–27); a score of 10 or higher is the usual treatment threshold, and item 9 screens for suicidal ideation.

GAD-7

A seven-item generalized-anxiety screen (0–21); a score of 10 or higher is clinically significant.

CIWA-Ar

The Clinical Institute Withdrawal Assessment for Alcohol (revised); a score of 8–10 or higher prompts symptom-triggered benzodiazepine dosing, and 15+ signals high risk for seizures and delirium tremens.

COWS

The Clinical Opiate Withdrawal Scale; a score of about 8–12 indicates enough withdrawal to safely induct buprenorphine without precipitating worse withdrawal.

MSE

Mental status exam — the structured documentation of appearance, behavior, speech, mood, affect, thought process and content, perception, cognition, insight, and judgment; the psychiatric counterpart of the physical exam.

motivational interviewing

A collaborative, patient-centered method to strengthen a person's own motivation for change using OARS (open questions, affirmations, reflective listening, summaries) while rolling with resistance.

CBT

Cognitive behavioral therapy — a structured, present-focused therapy that identifies and restructures cognitive distortions and uses behavioral activation; first-line for depression and most anxiety disorders.

DBT

Dialectical behavior therapy — an evidence-based therapy for borderline personality disorder and self-harm with four skill modules: mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness.

transtheoretical model

The stages-of-change model — precontemplation, contemplation, preparation, action, and maintenance (with possible relapse) — used to match interventions to a patient's readiness.

therapeutic alliance

The collaborative bond, shared goals, and agreed tasks between clinician and patient — the single strongest predictor of psychotherapy outcome.

trauma-informed care

An approach built on SAMHSA's four R's (realize, recognize, respond, resist re-traumatization) and six principles (safety; trustworthiness; peer support; collaboration; empowerment; cultural, historical and gender issues).

informed consent

A process — not just a signature — requiring capacity, disclosure of risks/benefits/alternatives, the patient's understanding, and voluntariness.

capacity

A clinical, decision-specific determination (made by a provider, and able to fluctuate) that a patient can make a particular decision; distinct from competency.

competency

A legal determination, made only by a court, of a person's global ability to manage their affairs — clinicians assess capacity, not competency.

Tarasoff

The duty to protect identifiable third parties from a patient's serious threat of violence (from Tarasoff v. Regents) — an exception to confidentiality that may require warning the victim, notifying police, or hospitalizing.

civil commitment

Involuntary psychiatric admission permitted only when a person, due to mental illness, is a danger to self, a danger to others, or gravely disabled — using the least restrictive option.

least restrictive environment

The principle that clinicians must use the least restrictive intervention that still ensures safety — voluntary before involuntary, outpatient before inpatient, verbal de-escalation before restraint.

HIPAA

The Health Insurance Portability and Accountability Act Privacy Rule, which protects PHI and permits its use for treatment, payment, and operations without separate authorization.

42 CFR Part 2

A federal rule, stricter than HIPAA, that protects the confidentiality of substance-use-disorder treatment records.

FMLA

The Family and Medical Leave Act — up to 12 weeks of unpaid, job-protected leave for an employee's or family member's serious health condition, including mental health.

Beers Criteria

The American Geriatrics Society list of potentially inappropriate medications in older adults — e.g., benzodiazepines and strongly anticholinergic drugs, which raise fall and delirium risk.
