Which of the following is NOT a disorder associated with psychosis?

Adjustment disorder is indeed not classified as a disorder associated with psychosis. Psychosis is characterized by a disconnection from reality, often including delusions or hallucinations, and is typically found in more severe mental health conditions.

In contrast, schizophrenia is a primary psychotic disorder that includes prominent symptoms such as hallucinations and delusions. Dementia can also feature psychotic symptoms, particularly in its advanced stages, where individuals may experience confusion and altered perceptions of reality. Delirium, which is a sudden and severe confusion or change in mental status, can involve psychotic features such as hallucinations or delusions as well.

Adjustment disorders, however, arise in response to specific stressors, leading to emotional or behavioral symptoms, but do not typically include the hallmark signs of psychosis. Instead, they manifest through anxiety, mood disturbances, or behavioral difficulties without a fundamental alteration in an individual's perception of reality.
