Social functioning in early psychosis: are all the domains predicted by the same variables?

Abstract

Aim: The study aims to determine the predictive value of negative symptoms, depression, short-term verbal learning and gender on three areas of social functioning--social life, vocational functioning and independent living skills--in a sample of 88 individuals with early psychosis.

Methods: Participants were recruited from early psychosis intervention programmes and community mental health clinics in British Columbia, Canada, and completed the following measures: client's assessment of strengths, interests, and goals, brief psychiatric rating scale, Beck depression inventory and California verbal learning task.

Results: Multiple linear regressions revealed that: more negative symptoms and higher depression predicted a less active social life; more negative symptoms and poorer short-term verbal learning ability predicted lower vocational functioning; and more negative symptoms and male gender predicted lower independent living skills.

Conclusion: Results suggest that negative symptoms are predictive of all three areas of functioning but that specific variables add significant unique variance to individual areas of social functioning. Although a global social functioning score can be considered useful, greater precision can be gained by the use of domain-specific measures.
