Final answer:
Regular follow-up with a mental health professional is the most likely intervention to prevent relapse in schizophrenia, as it allows for ongoing symptom management and support, contrasting sharply with the other listed options which would likely increase relapse risk.
Step-by-step explanation:
The question is asking which intervention is most effective in preventing relapse in schizophrenia. Among the options given, B) Regular follow-up with a mental health professional is the intervention most likely to prevent relapse in schizophrenia. Frequent check-ins with a healthcare provider allow for ongoing assessment and management of symptoms, adjustments to medications, and immediate intervention if signs of relapse appear. In contrast, discontinuation of medication, isolation from social support, and lack of psychoeducation are all associated with a higher risk of relapse. Patients with schizophrenia typically require lifelong treatment, which may include antipsychotic medications, psychotherapy, and other interventions to manage their symptoms and maintain stability.
