Despite the robust evidence base highlighting that paranoia is common in the nonclinical population, interventions to reduce non-clinical paranoia have not yet been examined. The aim of the study was to (I) investigate the effect of a brief mindfulness task on non-clinical paranoia, measured using a behavioural indicator (the Prisoner's Dilemma Game; PDG), and (2) determine whether Chadwick et al's (2005) model of responding mindfully to psychotic sensations applies to non-clinical paranoia, examining the relationship between cognitive processes and facets of mindfulness with paranoia. A student sample was used for the study (N = 60). Participants were randomly allocated to one of two conditions, brief mindfulness or control condition. Changes in paranoia and mindfulness were examined at baseline and following the intervention. Participants also completed trait measures of cognitive processes (experiential avoidance, judgement and rumination), mindfulness and paranoia. Three key findings emerged from the study; (1) state paranoia decreased and state mindfulness increased in both conditions, suggesting that both paranoia and mindfulness are amenable to experimental manipulation; (2) the findings suggest that the PDG provides a behavioural signature of state paranoia and (3) the cross sectional analysis suggests that cognitive processes operating in psychotic symptoms, as identified in Chadwick et al's (2005) model, also appear to occur in non-clinical paranoia. The findings provide further support to an emerging evidence base regarding mindfulness and paranoia and provide a foundation for further research into the application of mindfulness to non-clinical paranoia.
