Regarding symptom reduction, specialized FEP programs demonstrated decreases across positive, negative, and general symptoms. Cognitive Behavioral Therapy (CBT) interventions also showed promise in improving psychiatric symptoms, while skills training interventions were effective in enhancing positive and negative symptoms. Social and role functioning improvements were observed across different interventions, including specialized FEP care and vocational support. Furthermore, specialized FEP programs generally led to reduced hospitalization rates and improved continuity of care, while CBT and other interventions improved psychological outcomes, such as enhanced coping skills and cognitive functioning.
