Final answer:
Delusions of persecution are most frequently associated with paranoid schizophrenia. This subtype of schizophrenia is characterized by prominent delusions and auditory hallucinations, especially involving themes of being targeted or conspired against.
Step-by-step explanation:
Delusions of persecution are most common among those with paranoid schizophrenia. This form of schizophrenia is primarily characterized by the presence of pronounced delusions and auditory hallucinations, which often revolve around themes of persecution or grandiosity. Individuals with paranoid schizophrenia may feel that they are being targeted by others, spied on, or conspired against. Patients with this subtype may not exhibit the disorganized speech or behavior seen in other forms, such as disorganized schizophrenia, or the pronounced lack of movement seen in catatonic schizophrenia. While the residual type indicates that specific symptoms have lessened in intensity or have been resolved, the core characteristic of persecution delusions fits squarely within the symptoms of paranoid schizophrenia.
