"The Psychiatric Mental Status Examination" by Paula T. Trzepacz and Robert W. Baker provides a standardized framework for clinical assessment, focusing on six key domains: appearance, mood/affect, speech, thought/perception, cognition, and insight/judgment. This text is widely used in psychiatric education to define terminology and teach the documentation of mental functioning. For more information, visit Oxford Academic.

The Psychiatric Mental Status Examination by Paula T. Trzepacz
Paula T. Trzepacz and Robert W. Baker’s The Psychiatric Mental Status Examination (1993) provides a foundational framework for clinicians to systematically assess, organize, and document a patient's behavioral and cognitive functioning. The text details six core components—ranging from appearance to insight—that serve as a standardized tool for formulating diagnoses and monitoring clinical progress.

This text is widely considered the "gold standard" for learning how to properly conduct and document a Mental Status Examination (MSE). It moves beyond the simple checklists found in general psychiatry textbooks and provides a deep dive into the nuances of observation.
Here is a detailed review of the work, breaking down why it is highly rated and how it is used in clinical practice.
Her recommended format is descriptive, jargon-minimized, and hypothesis-driven. Appearance: Disheveled, wearing hospital gown, restless
Poor example: “Patient is anxious and has poor concentration.”
Trzepacz-style example:
Appearance: Disheveled, wearing hospital gown, restless. Behavior: Frequent shifting in seat, tapping feet. Speech: Rapid, pressured, difficult to interrupt. Mood: “Nervous.” Affect: Anxious, labile – tearful then irritable within minutes. Thought Process: Tangential – never returns to original question. Thought Content: No delusions, but endorses fear of losing control. Perception: Denies hallucinations. Cognition: Attention (digit span 4 forward, 2 reverse) – impaired. Short-term memory (3 objects at 5 min) – 1/3, with cueing improves to 2/3. Executive function: Proverb “glass houses” – concrete (“don’t throw rocks”). Insight: Partial – admits feeling different but denies need for medication. Judgment: Fair – would call family if anxious but not 911. wearing hospital gown
Interpretation: Profile consistent with generalized anxiety disorder with cognitive inefficiency. No psychosis. Impaired attention and executive function suggest frontal-subcortical involvement – consider medication effect or sleep deprivation.
While most textbooks define mood (subjective) vs. affect (observed), Trzepacz introduces the concept of lability and congruence. She stresses that a flat affect with a sad mood suggests catatonia or Parkinson’s, whereas a labile affect with a normal mood suggests pseudobulbar affect (neurologic) or histrionic personality.
Trzepacz emphasizes that all other MSE components are invalid if consciousness is impaired. She uses a hierarchy:
This is where Trzepacz shines. She provides a hierarchical taxonomy of disordered thinking:
