Background: A one-To-one cognitive behavioural therapy intervention targeting worry significantly reduces both worry and persecutory delusions (Freeman et al., 2015). Aim: To adapt this intervention for group delivery and conduct a feasibility trial within routine clinical practice. Method: Thirteen participants were randomized to a weekly 8-session worry intervention group (n = 7) or wait-list control (n = 6). Results: All but one participant completed measures at all time points. Participants attended an average of six therapy sessions. Conclusions: Recruitment, retention and therapy uptake were feasible. Observed treatment effects were in the expected direction, but may be diluted compared with one-To-one interventions.
