A person reports hearing voices that do not exist, disorganized thinking, emotional disturbance, and abnormal behavior for the past 6 months. According to DSM classification, this most likely falls under which category?

1. A

   Mood disorders

2. B

   Anxiety disorders

3. C

   Personality disorders

4. D

   Schizophrenia spectrum and psychotic disorders

Appeared in: AIIMS M.Sc. Nsg Entrance exam-2026

Explanation

• The patient's symptoms, including auditory hallucinations ('hearing voices') and disorganized thinking, are hallmark positive symptoms of psychosis.
• The duration of these symptoms for 'the past 6 months' meets the specific time criterion for a diagnosis of schizophrenia under the DSM-5.
• Schizophrenia is the primary diagnosis within the 'Schizophrenia spectrum and other psychotic disorders' category that fits this clinical picture.
• This category is defined by abnormalities in one or more of the five domains: delusions, hallucinations, disorganized thinking (speech), grossly disorganized or abnormal motor behavior (including catatonia), and negative symptoms.

Why Other Options Were Wrong

• Option A: Mood disorders are primarily defined by disturbances in mood (e.g., depression, mania). While psychosis can be a feature (e.g., in severe depression or bipolar disorder), it is not the core, defining element, and the primary disturbance is mood-related.
• Option B: Anxiety disorders are characterized by excessive fear, worry, and avoidance behaviors. They do not involve psychotic symptoms like hallucinations or disorganized thought as a core feature.
• Option C: Personality disorders involve long-standing, inflexible, and maladaptive patterns of behavior and inner experience. While some, like Schizotypal Personality Disorder, can have odd beliefs or perceptual experiences, they do not typically involve full-blown, persistent psychosis as described.

• Visual 2: Table - A comparative table outlining the key features of Schizophrenia, Schizoaffective Disorder, and Bipolar Disorder with Psychotic Features to highlight the differences.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Diagnosis and classification of major psychiatric disorders based on DSM-5 criteria as background academic context rather than a clinical decision trigger.
• A nurse's primary role for a patient with new-onset psychosis is to ensure safety for the patient and others, as disorganized thoughts and hallucinations can lead to unpredictable behavior.
• Accurate assessment and documentation of the type, content, and duration of symptoms are crucial for aiding in the correct diagnosis and developing an effective care plan.
• What if? - If the symptoms had only been present for three months, the diagnosis would likely be Schizophreniform Disorder, not Schizophrenia. The treatment approach would be similar, but the long-term prognosis would be considered more uncertain until the 6-month mark is passed.

How to Approach the Question

• First, identify the key clinical features presented in the scenario: auditory hallucinations, disorganized thinking, and abnormal behavior.
• Next, note the specified duration of the symptoms, which is 'the past 6 months'. This is a critical piece of diagnostic information.
• Systematically evaluate each option. Consider the defining characteristics of mood disorders (mood disturbance), anxiety disorders (fear/worry), and personality disorders (enduring behavioral patterns).
• Recognize that the core features described (hallucinations, thought disorder) are psychotic symptoms.
• Match the combination of psychotic symptoms and the 6-month duration to the diagnostic criteria for the disorders in each category.
• Conclude that the 'Schizophrenia spectrum and psychotic disorders' category is the only one that fits all the presented criteria, specifically pointing to a diagnosis of Schizophrenia.

Concept Tested & Keywords

• Concept Tested: Diagnosis and classification of major psychiatric disorders based on DSM-5 criteria.
• Stem keywords: hearing voices, disorganized thinking, abnormal behavior, 6 months, DSM classification
• Lead-in keywords: most likely
• Clinical cues: The 6-month duration is a critical diagnostic criterion for schizophrenia, distinguishing it from shorter-term psychotic disorders like schizophreniform disorder.
