Background: Social network has considerable impact on physical and mental health. Patients experiencing first-episode psychosis early in adult life may experience severe problems concerning development and maintenance of their social network.
Methods: A total of 547 first-episode psychotic patients (18-45) were randomised to standard or integrated treatment, (ACT, social skills training and family intervention), and followed up at 2 years.
Results: Service use or psychotic symptom score did not influence the social network size, measured after the first 2 years of treatment. Small network size was associated with long duration of untreated psychosis (DUP), poor premorbid adjustment, male gender and severe negative symptoms. The number of friends at 2-year follow-up was predicted by age, A-level status, negative symptoms and number of friends at entry, while the determinants for number of family contacts were age, gender, disorganised dimension and family contacts at entry.
Conclusions: Premorbid functioning, network size at entry and DUP is closely related to small social network size. The integrated psychosocial treatment programme was not sufficient to address this problem.
