The guest, his family and the crisis center are composite; the manual, reviews and trial cited are real.
The Case
Corey, 23, first appeared in this course in Unit 1, when a sheriff's deputy drove him to the center after he pounded on a neighbor's door demanding they stop broadcasting his thoughts. Over his five-day stay and the weeks that followed, a fuller history emerged.
Corey grew up in a small town east of the Black Hills and moved to Rapid City at 19 to work at a tire shop. His family describes him as quiet but sociable through high school. About seven months before the crisis, he began withdrawing from friends, missing work and spending nights online. He smoked high-potency cannabis daily, sometimes several times a day, a habit that began at 15. About five weeks before the crisis, he started to believe that people on his street could hear his thoughts through the wiring in his apartment and were repeating them back to him in conversations he overheard. He stopped sleeping, lost his job and covered his outlets with tape.
His cousin on his father's side was diagnosed with schizophrenia at 20. Corey has no history of mania or major depression, and a medical workup, including blood tests and a brain scan, found no other cause. A urine screen was positive only for cannabis.
Diagnosis
The DSM-5-TR sorts psychotic symptoms into five groups. Three are the positive symptoms most people picture: delusions, hallucinations and speech or thinking too disorganized to follow. The fourth covers strange or disorganized movement and behavior, including catatonia. The fifth, negative symptoms, covers what is lost, such as emotional expression and drive (American Psychiatric Association, 2022). Schizophrenia requires at least two of these, including at least one of the first three, with some sign of the disturbance persisting across a span of six months or more, along with slipping performance at work, in relationships or in self-care. Schizophreniform disorder has the same symptom picture but lasts between one and six months.
Corey has delusions of thought broadcasting and possibly auditory hallucinations, if the overheard conversations were not real. He also shows negative symptoms: withdrawal, loss of motivation and flattened expression. His total period of disturbance, counting the withdrawal that began seven months ago as a prodrome, may already exceed six months, but the active psychotic symptoms began five weeks before admission. The psychiatric nurse practitioner diagnosed schizophreniform disorder, provisional, noting that the diagnosis would change to schizophrenia if symptoms persisted.
Two alternatives were considered. Substance-induced psychotic disorder was possible given his heavy cannabis use, but his symptoms persisted for weeks after he stopped using in the center, which points to an independent disorder. A mood disorder with psychotic features was unlikely given no history of mania or depression.
Corey's diagnosis is provisional not because the clinicians doubt his suffering, but because the time course will decide what it is.
Explaining the Disorder
Howes and Kapur (2009) proposed a revised dopamine hypothesis of schizophrenia. They argued that many different risk factors, including genes, early brain injury, social adversity and drug use, converge on a final common pathway: dysregulated dopamine release in the striatum, mainly at the presynaptic level. Excess dopamine, in their account, assigns importance, or salience, to ordinary perceptions and thoughts. A person then builds explanations for why everyday events suddenly seem meaningful, and those explanations become delusions.
The model helps explain Corey's experience. Conversations on his street, once background noise, began to feel charged and personal. His explanation, that neighbors were hearing and repeating his thoughts, made sense of that feeling. Antipsychotic medication, which blocks dopamine receptors, reduced the intensity of that salience within days, though the belief faded more slowly.
The model also makes room for his risk factors. His cousin's illness suggests some genetic vulnerability. His cannabis use is a second hit. Pooling studies that recorded how much cannabis people used, Marconi et al. (2016) found that psychosis risk climbed with each step up in use, with the heaviest users facing roughly four times the risk of nonusers. Daily use of high-potency cannabis beginning in adolescence places Corey in the highest-risk group. Cannabis did not by itself cause his illness, but it likely contributed to its timing and severity.
Treatment
Early, comprehensive treatment matters in first-episode psychosis. Kane et al. (2016) tested a coordinated specialty care program in a cluster-randomized trial at 34 community clinics, part of the federal RAISE initiative. Clients received a team-based package that included personalized medication management at low doses, individual resilience-focused therapy, family education and supported employment and education. Over two years, clients in the program improved more than those in usual community care on quality of life and on symptoms, and they spent more time working or in school. The benefits were greater for those whose untreated psychosis had lasted a shorter time. That finding is one reason crisis centers like ours try to connect young people with specialty teams quickly, rather than sending them home with pills and a clinic date months out.
Corey's untreated psychosis lasted about five weeks, well below the median in the trial, which makes him a good candidate. The crisis center counselor referred him to a coordinated specialty care team that serves the region through a combination of in-person and video visits. His plan includes antipsychotic medication at the lowest effective dose, individual therapy focused on understanding his experience and reducing cannabis use, family education for his parents, who drove from home every day of his stay, and supported employment to help him return to work at a tire shop or train for something new.
Prognosis
A first episode of psychosis does not determine a lifetime course. Some people recover fully, some have further episodes and some develop chronic illness. Factors in Corey's favor include good functioning before the prodrome, a short duration of untreated psychosis, family support and his willingness to accept care. Factors against him include his cousin's illness, the negative symptoms that began early and the difficulty of stopping cannabis. Whether his diagnosis becomes schizophrenia will depend on what happens over the next several months.
Conclusion
Corey's first episode of psychosis fits the criteria for schizophreniform disorder and the revised dopamine hypothesis, which links his family risk and heavy cannabis use to the sudden significance he found in his neighbors' conversations. The strongest evidence for treatment supports early, coordinated care that addresses medication, therapy, family and work together. The crisis that brought him to us at 3 a.m. may yet be the start of a recovery.

Reading the PS 440 Unit 6 instructions
Unit 6 of PS440 asks you to analyze a psychotic disorder case. Present the history, including any prodrome, substance use and family history, and the medical workup. Apply the diagnostic criteria, explaining how duration distinguishes related disorders, and consider alternatives such as substance-induced or mood disorders. Explain the disorder using current biological and environmental research, including the evidence for risk factors such as cannabis. Evaluate treatment evidence, especially for first-episode care, and propose a plan that includes family and work or school. Discuss prognosis honestly. Use APA style with the manual, review articles and trial evidence, in a paper of about five pages. Use composite details only.
Inside the PS440 Unit 6 example
The paper picks up Corey's story from Unit 1, tracing his move to Rapid City, his withdrawal and cannabis use, the onset of his beliefs and his cousin's illness. A diagnosis section groups psychotic symptoms in plain terms, explains why duration makes his diagnosis provisional, under a highlighted line that time will decide, and rules out alternatives. An explanation section applies the dopamine hypothesis to his experience of salience and places cannabis as one contributing factor with dose-response evidence. A treatment section describes the coordinated specialty care trial and his referral. A prognosis section weighs factors for and against recovery, and the conclusion returns to the night he arrived. The tone stays hopeful but realistic.
PS440 Unit 6 rubric: what earns full points
Instructors grading the psychotic disorder paper look for accurate use of criteria, especially duration, which separates schizophreniform disorder from schizophrenia. Alternatives must be considered with reasons. The biological explanation earns credit when it connects a model such as the dopamine hypothesis to the person's experience rather than describing neurotransmitters in general. Risk factors like cannabis should be presented with evidence and without overstatement. Treatment sections should reflect the evidence for early, coordinated care. A balanced prognosis shows understanding of variable outcomes. Respectful language about psychosis is expected, along with APA citations for each claim. Strong papers also explain why early treatment matters for outcomes, using the trial's findings on duration of untreated psychosis.
PS440 Unit 6 help from the desk
Psychosis papers often jump to a schizophrenia diagnosis without checking duration. Others describe the dopamine hypothesis as a simple excess of dopamine causing all symptoms. Cannabis is sometimes presented as the sole cause, or dismissed entirely. Treatment sections frequently mention only medication. Prognosis is often either hopeless or unrealistically optimistic. To improve a draft, count the months of each phase of the illness, explain one symptom through the biological model, cite a source for any risk factor, include family and work in the plan, and list at least two factors on each side of the prognosis. Those details show careful clinical reasoning. Keep the language respectful.

PS440 Unit 6 questions, answered
What is first-episode psychosis?
The first period in which a person loses touch with reality, often in late adolescence or early adulthood.
What is coordinated specialty care?
Team-based early treatment combining medication, therapy, family education and work or school support.
Is schizophrenia caused by dopamine?
Dopamine dysregulation is a common pathway, but genetic and environmental factors contribute.
Where can I find a free PS440 Unit 6 sample paper?
This page holds the complete PS440 Unit 6 case analysis of a composite young man's first episode of psychosis.
Why is the diagnosis provisional in the PS440 Unit 6 sample?
Active psychotic symptoms had lasted only weeks, so schizophreniform disorder applies until the six-month duration for schizophrenia is reached or symptoms resolve.
