Final answer:
A good prognosis in schizophrenia is associated with rapid onset of symptoms, female gender, and good premorbid functioning, but not necessarily an acute onset of symptoms, which can be severe and sudden.
Step-by-step explanation:
Features that weigh towards a good prognosis in schizophrenia include all of the following EXCEPT: D) Acute onset of symptoms. Factors associated with a better prognosis in schizophrenia often comprise a rapid onset of symptoms (A), female gender (B), and good premorbid functioning (C). While both 'acute' and 'rapid' may seem similar in meaning, in the context of schizophrenia, 'acute' often refers to symptoms that appear suddenly and are typically severe. A rapid onset can be favorable if symptoms are swiftly recognized and treated, but an acute onset does not necessarily equate to 'rapid' in this medical context. Women with schizophrenia generally have a better prognosis than men, possibly due to hormonal factors. Additionally, individuals who had higher levels of functioning before the onset of schizophrenia tend to experience a less severe course. In contrast, a gradual or insidious onset is associated with a poorer prognosis, not the acute onset of symptoms.
