psychotic
Examining the effect of the interventions on the point prevalence of PEs at follow-up.Over the course of the study 11% (n = 120) of study participants reported PEs on at least one occasion. PEs were reported by 7.1% (n = 76) of participants at baseline, 5.3% (n = 5) at 3-months and 4.5% (n = 42) at 12-months.
Effect sizes for each intervention arm at 3 months and 12 months on point prevalence & incidence of PEs.* = Other characteristics include age, gender, nationality and physical victimisation.There was no significant main effect of intervention arm, time or interaction between intervention arm and time at 3-months follow-up. At 12-months follow-up, there was a significant interaction indicating a reduction in the point prevalence of PEs in the ProfScreen arm when compared to the Control arm (Fig. Excluding those who reported PEs at baseline, there was no significant main effect at 3-month for any intervention arm(Table
