Background:

• Schizophrenia is a complex mental disorder requiring accurate diagnosis and management.
• Primary care physicians play a crucial role in the initial identification and referral of patients with schizophrenia.

Main Results:

• General practitioners demonstrated good recognition of positive (79.0%), negative (72.6%), and general (72.1%) schizophrenia symptoms.
