Group-Based Worry Intervention for Persecutory Delusions: an Initial Feasibility Study

<jats:p><jats:bold>Background:</jats:bold> A one-to-one cognitive behavioural therapy intervention targeting worry significantly reduces both worry and persecutory delusions (Freeman et al., 2015). <jats:bold>Aim:</jats:bold> To adapt this intervention for group delivery and conduct a feasibility trial within routine clinical practice. <jats:bold>Method:</jats:bold> Thirteen participants were randomized to a weekly 8-session worry intervention group (<jats:italic>n</jats:italic> = 7) or wait-list control (<jats:italic>n</jats:italic> = 6). <jats:bold>Results:</jats:bold> All but one participant completed measures at all time points. Participants attended an average of six therapy sessions. <jats:bold>Conclusions:</jats:bold> 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.</jats:p>
