Assess: Building a Defensible Psychiatric Database
What the Assess domain rewards
Assessment questions test whether you can gather and organize data before naming a disorder. Know the components of a complete psychiatric evaluation: chief complaint in the patient's words, history of present illness (onset, duration, course, severity, triggers, function), past psychiatric and medical history, substance use, medications and adherence, family history, social/developmental history, trauma history, and mental status examination. Be fluent in MSE vocabulary (appearance, behavior, speech, mood vs. affect, thought process vs. content, perception, cognition, insight, judgment) and in validated screening tools: PHQ-9, GAD-7, AUDIT-C, C-SSRS, MMSE/MoCA, and the CAGE or DAST for substance use.
Traps to expect
- Mood vs. affect: mood is the patient's self-report; affect is your observation.
- Screening vs. diagnosis: a positive screen (e.g., PHQ-9 of 15) flags severity but does not diagnose; diagnosis requires criteria-based evaluation.
- Collateral information: questions often hinge on whether you sought a family or caregiver report, especially in suspected dementia, psychosis, or pediatric cases.
- Safety assessment timing: suicide and violence risk must be assessed early and documented, not deferred.
- Substance use as confounder: intoxication or withdrawal can mimic nearly any psychiatric syndrome; questions reward ruling it out first.
Rule of thumb
Before naming a diagnosis, confirm the assessment is complete for the question asked: if the vignette omits duration, functional impact, or substance use, the best answer is usually the next assessment step, not a treatment.
Worked example
A 68-year-old presents with three months of progressive memory loss and one episode of getting lost while driving. The question asks the first action. Answer: obtain collateral history and formal cognitive testing (e.g., MoCA) plus medication and metabolic review, not start a cholinesterase inhibitor. Diagnosis is premature until reversible causes and baseline function are established.
