A decision before an answer
- A short vignette gives symptoms and duration but omits impairment, exclusions and context. What is still unknown?
- Your goal: Interpret diagnostic evidence under the recorded DSM-5-TR framework without diagnosing from incomplete vignettes.
Identify the recorded framework
- The recorded framework is DSM-5-TR.
- Clinical classification describes patterns; a category does not establish the cause of a presentation. Historical ETS items must be interpreted against their recorded source version.
A classroom vignette gives two symptoms and a duration, but omits impairment and exclusions. Which conclusion is justified?
The missing criterion domains prevent a complete classification; duration alone is insufficient.
Check all criterion domains
- Symptoms, duration, clinically significant distress or impairment, context and exclusions must be considered together.
- A short duration does not by itself establish acute stress disorder or any other diagnosis.
In the diathesis-stress model, a family history of schizophrenia together with a recent bereavement maps onto:
The pre-existing vulnerability is the diathesis; the later trigger is the stress.
Separate vulnerability and later stress
- The diathesis-stress model examines how vulnerability and environmental stress jointly affect risk.
- Neither a family history nor a later event establishes an inevitable outcome or a universal necessity/sufficiency rule.
A fictional vignette supplies a recent adverse event and two symptoms but omits impairment, exclusions and a full assessment. What conclusion is justified? The vignette identifies relevant evidence and missing information. It cannot establish a diagnosis. A duration threshold alone cannot turn a short account into an alternative disorder. The correct educational response is to name the missing criterion domains and source/version, not supply personal advice.
A factor present before a later stressor is a possible ____.
A diathesis is a vulnerability, not proof that a disorder must occur.
Limit educational comparisons
- Common educational distinctions include added experiences versus reduced functions in symptom descriptions, and episodic presentations versus enduring patterns.
- Full current criteria require an authenticated manual; the available GRE practice book is not that manual.
Do not infer a diagnosis from duration or a few symptoms, or offer personal treatment advice.
Which answer fits this case?
Interpret diagnostic evidence under the recorded DSM-5-TR framework without diagnosing from incomplete vignettes
A DSM-5-TR diagnosis states the cause of a person's disorder.
The manual is descriptive: it classifies presentations and does not assert aetiology.
Keep the distinctions
- diagnostic criteria 诊断标准 — The listed symptom, duration, impairment and exclusion requirements for a classification.
- diathesis-stress model 素质-应激模型 — An account of how vulnerability and environmental stress jointly affect risk.
- Interpret diagnostic evidence under the recorded DSM-5-TR framework without diagnosing from incomplete vignettes.
- Apply the diathesis-stress model to separate predisposition from trigger.
- Distinguish commonly confused disorders by their defining features.
