Review the vignettes located in the topic five materials and then diagnose Robin and Becky with a psychotic disorder. What are the justifications for your diagnosis? Include differential diagnoses that were considered and discarded.


Psychotic disorders are a complex group of mental illnesses characterized by disruptions in perception, thinking, and behavior. In order to diagnose individuals with psychotic disorders, careful assessment and consideration of various factors are required. This assignment aims to analyze the vignettes of two individuals, Robin and Becky, and provide a diagnosis of psychotic disorder for each, along with the justifications for these diagnoses. Additionally, this assignment will explore the relevant differential diagnoses that were considered and discarded in the process.

Vignette Analysis: Robin

Robin, a 26-year-old male, presents with a range of symptoms indicative of a psychotic disorder. Firstly, Robin experiences hallucinations, specifically auditory hallucinations, wherein he reports hearing voices that others cannot perceive. This symptom aligns with one of the key criteria for diagnosing psychotic disorders, as outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Furthermore, Robin’s hallucinations involve derogatory and threatening voices, which is consistent with the subtype of psychosis known as paranoid psychosis.

In addition to auditory hallucinations, Robin displays disorganized thinking and speech, suggesting the presence of thought disorder. His speech is often tangential and lacks coherence, making it difficult for others to follow his train of thought. This symptom further supports the diagnosis of a psychotic disorder, as impaired thinking is a prominent characteristic of such conditions.

Robin also exhibits social withdrawal and a decline in functioning. He has isolated himself from his friends and family, and his work performance has significantly deteriorated. This change in behavior and functioning is often associated with psychotic disorders, as individuals struggle to maintain personal relationships and engage in daily activities due to the disturbances caused by their symptoms.

Justification for Diagnosis: Robin

Based on the presented symptoms, Robin can be diagnosed with paranoid schizophrenia. Paranoid schizophrenia is a psychotic disorder characterized by active symptoms of psychosis, including hallucinations and delusions, such as the belief that others are plotting against or persecuting the individual. Robin’s auditory hallucinations involving threatening voices align with the paranoid subtype of schizophrenia and further support this diagnosis. Furthermore, Robin’s disorganized thinking and speech, along with his social withdrawal and functional decline, are consistent with the diagnostic criteria for schizophrenia.

Differential Diagnoses Considered and Discarded: Robin

During the diagnostic process, it is important to consider alternative diagnoses that may explain the observed symptoms but are not indicative of a psychotic disorder. In Robin’s case, a major depressive disorder with psychotic features and substance-induced psychosis were potential differential diagnoses to consider.

A major depressive disorder with psychotic features might present with symptoms similar to Robin’s, such as auditory hallucinations and social withdrawal. However, the key distinguishing factor is the presence of a major depressive episode, which Robin does not manifest. Consequently, this differential diagnosis can be discarded.

Similarly, substance-induced psychosis may display symptoms akin to Robin’s, particularly if he is using substances known to induce psychosis, such as hallucinogens or amphetamines. However, Robin’s symptoms have persisted for a significant duration, and there is no mention of substance use in the vignette. Therefore, substance-induced psychosis can also be discarded as a differential diagnosis.

To conclude, the combination of hallucinations, disorganized thinking and speech, social withdrawal, and functional decline supports the diagnosis of paranoid schizophrenia for Robin. This diagnosis is justified by the alignment of his symptoms with the diagnostic criteria for psychotic disorders, specifically paranoid schizophrenia. Alternative differential diagnoses, such as major depressive disorder with psychotic features and substance-induced psychosis, do not fit the presented symptoms and can be discarded.
