      Social functioning difficulties are a common and disabling feature of psychosis and have also been identified in the prodromal phase. However, debate exists about how such difficulties should be defined and measured. Time spent in structured activity has previously been linked to increased psychological wellbeing in non-clinical samples and may provide a useful way of assessing social functioning in clinical settings. The current study compared weekly hours in structured activity, assessed with the Time Use Survey, in three clinical groups at different stages of psychosis: individuals with at-risk mental states (N = 199), individuals with first-episode psychosis (N = 878), and individuals with delayed social recovery following the remission of psychotic symptoms (N = 77). Time use in the three clinical groups was also compared with norms from an age-matched non-clinical group (N = 5686) recruited for the Office for National Statistics UK 2000 Time Use Survey. Cut-off scores for defining social disability and recovery were examined. All three clinical groups spent significantly fewer hours per week in structured activity than individuals in the non-clinical group. Reduced activity levels were observed before the onset of psychosis in individuals with at-risk mental states. Additional reductions in activity were observed in the first-episode psychosis and delayed recovery groups compared to the at-risk mental state group. Assessing time spent in structured activity provides a useful way to assess social disability and recovery across the spectrum of psychosis.

      AIMS: To investigate trajectories of negative symptoms during the first 12months of treatment for first episode psychosis (FEP), their predictors and relationship to social recovery. METHOD: 1006 participants were followed up for 12months following acceptance into Early Intervention in Psychosis services. Negative symptom trajectories were modelled using latent class growth analysis (LCGA) and predictors of trajectories examined using multinomial regression. Social recovery trajectories - also modelled using LCGA - of members of each negative symptom trajectory were ascertained and the relationship between negative symptom and social recovery trajectories examined. RESULTS: Four negative symptom trajectories were identified: Minimal Decreasing (63.9%), Mild Stable (13.5%), High Decreasing (17.1%) and High Stable (5.4%). Male gender and family history of non-affective psychosis predicted stably high negative symptoms. Poor premorbid adolescent adjustment, family history of non-affective psychosis and baseline depression predicted initially high but decreasing negative symptoms. Members of the Mild Stable, High Stable and High Decreasing classes were more likely to experience stably low functioning than the Minimal Decreasing class. CONCLUSIONS: Distinct negative symptom trajectories are evident in FEP. Only a small subgroup present with persistently high levels of negative symptoms. A substantial proportion of FEP patients with elevated negative symptoms at baseline will achieve remission of these symptoms within 12months. However, elevated negative symptoms at baseline, whether or not they remit, are associated with poor social recovery, suggesting targeted interventions for service users with elevated baseline negative symptoms may help improve functional outcomes.
