Psychiatric Assessment

Must know

• Table: Psychiatric Assessment Goals and PurposeFirst-line goal: Establish rapport and construct a therapeutic relationship to reduce autonomic anxiety and foster patient engagement.

  • First-line goal: Establish rapport and construct a therapeutic relationship to reduce autonomic anxiety and foster patient engagement.
  • Assessment time frame: Determine within 10 to 15 minutes whether a patient requires inpatient hospitalization versus outpatient care based on immediate safety risks.
  • Acute behavioral change in older adults: A sudden onset of psychiatric symptoms over 2 days (48 hours) in an older adult indicates delirium, which is a medical emergency requiring immediate referral to the emergency department.
  • Suicide risk and active intent: Active suicidal ideation with a specific plan and access to lethal means such as a firearm requires immediate inpatient hospitalization.
  • HIPAA and collateral information: The provider must obtain a signed release of information before gathering collateral history from family members or roommates, even if they live together.
  • Baseline lab work: Initial treatment planning requires ordering baseline laboratory tests including BMP (renal function), LFTs, TSH, and CBC.
• Assessment Goals and Core PurposeThe primary initial step in any psychiatric assessment is establishing rapport and ensuring physical safety before attempting complex diagnostic questioning.

• Table: Components of the Psychiatric InterviewThe chief complaint must be recorded in the patient's own words using exact quotes, serving as an authentic baseline for tracking treatment progress and building rapport.

  • The chief complaint must be recorded in the patient's own words using exact quotes, serving as an authentic baseline for tracking treatment progress and building rapport.
  • A thorough history of present illness must evaluate episode onset, precipitating triggers, symptom intensity, duration, and specific impairment in daily functioning, as DSM-5-TR criteria require documented functional impairment.
  • Medication history requires surveying all prescribed psychotropics, last dose taken, adherence patterns, over-the-counter products, and herbal supplements to prevent drug interactions, serotonin syndrome, or withdrawal.
  • Family history must extend beyond the nuclear family to grandparents, aunts, uncles, and cousins, specifically screening for psychiatric disorders, substance abuse, suicides, hospitalizations, and incarceration history.
  • Substance use history requires documenting exact drug types, amounts, age of first and last use, longest sobriety period, detox history, and severe withdrawal complications like seizures or delirium tremens.
  • Social history must screen for housing insecurity, legal charges like bankruptcies or drug possession, trauma exposure, and military service details including military sexual trauma and VA healthcare eligibility.
• Identifying Data and Referral ContextStart the encounter by clarifying appointment goals, explaining interview flow, and making an empathetic observation to establish rapport.

  • What it is: The foundational opening section of the psychiatric evaluation recording referral sources, reviewed records, and historian reliability.
  • Why boards care: Test items evaluate whether you correctly assess historian reliability and obtain proper legal authorization before gathering collateral information.
  • Document who referred the patient and why, what prior medical or psychiatric records were reviewed (such as hospital discharge summaries), and a formal statement rating historian reliability as adequate, fair, or poor.
  • Start the encounter by clarifying appointment goals, explaining interview flow, and making an empathetic observation to establish rapport.
  • When an adult patient is guarded or uncommunicative, you must obtain a signed release of information before contacting family members or collateral sources to avoid HIPAA privacy violations.

  Safety. When an adult patient is guarded or uncommunicative, you must obtain a signed release of information before contacting family members or collateral sources to avoid HIPAA privacy violations.

• Chief Complaint and History of Present IllnessWhat it is: The core narrative describing the presenting problem in verbatim patient quotes and detailing the current psychiatric episode.

  • What it is: The core narrative describing the presenting problem in verbatim patient quotes and detailing the current psychiatric episode.
  • Why boards care: Exams test your ability to differentiate subjective symptoms from objective signs and identify functional impairment across daily living activities.
  • Evaluate symptom onset, precipitating stressors, symptom timing, intensity, duration, physical manifestations of distress, and why the patient is seeking care at this specific time.
  • Choosing a primary psychiatric diagnosis when symptoms lack documented functional impairment or have an acute onset stemming from a medical condition.

  Board trap. Choosing a primary psychiatric diagnosis when symptoms lack documented functional impairment or have an acute onset stemming from a medical condition.

• Past Medical, Psychiatric, and Medication SurveyWhat it is: A comprehensive inventory of all past psychiatric episodes, medical conditions, and full medication usage.

  • What it is: A comprehensive inventory of all past psychiatric episodes, medical conditions, and full medication usage.
  • Why boards care: Uncovering prior suicide attempts, past hospitalizations, or previous psychotropic failures directly dictates emergency risk management and drug selection.
  • Record all past psychiatric diagnoses, previous psychotropic trials, hospitalizations, self-harm history, primary care provider name, and date of last physical exam.
  • Always survey prescribed medications, last dose taken, adherence patterns, over-the-counter products, and herbal supplements to prevent serotonin syndrome, CYP450 interactions, or abrupt withdrawal.

  Safety. Always survey prescribed medications, last dose taken, adherence patterns, over-the-counter products, and herbal supplements to prevent serotonin syndrome, CYP450 interactions, or abrupt withdrawal.

• Family, Substance, and Social HistoryWhat it is: A deep exploration of genetic predisposition, chemical dependencies, personal development, and social determinants of health.

  • What it is: A deep exploration of genetic predisposition, chemical dependencies, personal development, and social determinants of health.
  • Why boards care: Board questions frequently hide diagnostic clues in family incarceration, military trauma, housing instability, or alcohol withdrawal history.
  • Family history must survey psychiatric illness, substance abuse, suicides, hospitalizations, and incarceration across extended relatives. Substance history requires logging first and last use, amounts, longest sobriety, and withdrawal seizures or delirium tremens. Social history explores housing security, relationship stability, education, employment, legal history, military service, and trauma history using broad screening prompts.
• Review of SystemsWhat it is: A systematic head-to-toe physical screening to identify medical mimics and physiological drivers of psychiatric distress.

  • What it is: A systematic head-to-toe physical screening to identify medical mimics and physiological drivers of psychiatric distress.
  • Why boards care: Board items require PMHNPs to rule out medical conditions such as thyroid dysregulation, cardiopulmonary compromise, or pregnancy prior to prescribing.
  • Systematically review neurological, endocrine, infectious, and cardiopulmonary systems. In female patients, systematically document menstrual cycle regularity, contraception, current pregnancy, and future pregnancy plans.
• Insight vs. JudgmentThink Insight when: The patient demonstrates awareness of their psychiatric illness, symptom origin, and functional impairment.

  • Think Insight when: The patient demonstrates awareness of their psychiatric illness, symptom origin, and functional impairment.
  • Think Judgment when: The patient demonstrates the capacity to make sound decisions and execute actions that protect their health and safety.
  • Priority difference: Insight is an understanding of illness (such as knowing hallucinations are not real), whereas judgment is a decision-making capability (such as taking daily medications to prevent relapse or checking in with a case manager).
  • What boards are testing: Recognizing that a patient can have intact judgment regarding treatment adherence even when dealing with chronic psychiatric illness.
• Delirium vs. Primary Psychiatric RecurrenceThink Delirium when: An older adult experiences an acute, sudden change in mental status or behavior over hours to days with fluctuating alertness or visual hallucinations.

  • Think Delirium when: An older adult experiences an acute, sudden change in mental status or behavior over hours to days with fluctuating alertness or visual hallucinations.
  • Think Primary Psychiatric Recurrence when: A patient experiences a gradual return of known baseline symptoms without acute medical instability or vital sign changes.
  • Priority difference: Delirium is a life-threatening medical emergency requiring immediate transfer to the emergency department, whereas psychiatric recurrence is managed through outpatient medication or therapy adjustment.
  • Prescribing PRN antipsychotics like olanzapine or haloperidol for acute confusion in an elderly patient before completing a medical emergency workup.

• Table: Mental Status Examination Components (ABSATTC)The Mental Status Examination evaluates current psychiatric functioning across seven core domains using the ABSATTC framework: Appearance and behavior, Behavior and motor activity, Speech, Affect and mood, Thought content and process, Perceptual disturbances, and Cognition, insight, and judgment.

  • The Mental Status Examination evaluates current psychiatric functioning across seven core domains using the ABSATTC framework: Appearance and behavior, Behavior and motor activity, Speech, Affect and mood, Thought content and process, Perceptual disturbances, and Cognition, insight, and judgment.
  • Cognition requires active objective testing rather than passive observation, including orientation to person, place, time, and year, serial sevens subtraction from 100 or backward month recitation for concentration, and 3-word recall for short-term memory.
  • Delirium is an acute medical emergency characterized by fluctuating alertness and impaired concentration, requiring immediate referral to an emergency department rather than psychotropic dose adjustments like adding olanzapine.
  • Thought process abnormalities distinguish circumstantiality (overinclusive details that eventually return to the goal, common in generalized anxiety disorder) from tangentiality (wandering off-topic without ever returning to the original question, common in schizophrenia).
  • Speech latency involves a 3 to 5 second pause before answering simple questions, reflecting slowed cognitive processing in schizophrenia or severe depression, whereas pressured speech indicates bipolar disorder mania or hypomania.
  • Insight measures the patient's awareness of their psychiatric illness and need for treatment, whereas judgment evaluates their capacity to make sound decisions, such as adhering daily to medications like lithium or risperidone to prevent psychotic relapses.

  Safety. Active suicidal ideation with access to lethal means like a firearm requires immediate inpatient hospitalization rather than waiting 2 weeks or increasing an SSRI dose.

• Appearance, Behavior, and AttitudeFirst-line intervention for an angry, uncooperative patient in the emergency department is initiating communication with an empathetic statement that validates nonverbal cues and identifies a plausible trigger, such as being brought in by police.

• Affect and MoodMood is the patient's internal, subjective emotional state described in their own words or rated on a 0 to 10 scale where 6 or 7 represents normal contentment.

  • Mood is the patient's internal, subjective emotional state described in their own words or rated on a 0 to 10 scale where 6 or 7 represents normal contentment.
  • Affect is the objective, clinician-observed emotional expression. Group and compare affect parameters: quality can be euthymic, dysphoric, or irritable; range spans normal, restricted, or labile; intensity varies from mild to severe; and affect must be evaluated for appropriateness to the situation and congruence with stated mood. Avoid non-descriptive labels like neutral.
• Thought Content and Thought ProcessThought content incorporates ideas occurring spontaneously or upon questioning, including obsessions, ruminations, delusions, passive or active suicidal ideation, and homicidal ideation.

  • Thought content incorporates ideas occurring spontaneously or upon questioning, including obsessions, ruminations, delusions, passive or active suicidal ideation, and homicidal ideation.
  • Thought process reflects how thoughts are formulated, organized, and expressed through speech. Normal thought process is linear, organized, and goal-directed.
