Mindfulness and Paranoia: A Cross-Sectional, Longitudinal and Experimental Analysis

Objectives The purpose of this article was to examine the role of mindfulness, and its facets, in predicting (Studies 1 and 2) and attenuating (Study 3) paranoia in students. Methods Study 1 used cross-sectional questionnaire-based methodology (N = 410) to examine the association between mindfulness and paranoia whilst controlling for their shared association with anxiety and depression. Study 2 used longitudinal design to test the prospective influence of mindfulness facets on state paranoia over a 2-week period (N = 84). Study 3 used a single-blind between-group experimental design to examine the effects of 1-week self-administered mindfulness training (N = 34) versus 1-week self-administered guided visual imagery (GVI) training (N = 34) on state paranoia. Results In study 1, controlling for anxiety and depression, low levels of non-judgement were significantly associated with high levels of paranoia (p < .001). In study 2, high levels of non-judgement buffered the impact of trait paranoia on daily experiences of state paranoia, whilst statistically controlling for the influence of rumination (interaction: p = .02). In study 3, both mindfulness and GVI significantly reduced state paranoia (p < .001). Conclusion Findings highlight the importance of mindfulness, and non-judgement specifically, in understanding paranoia in students and provide further evidence for mindfulness and relaxation as effective methods for reducing paranoia. Across studies, participants were predominantly white female students. Findings cannot, therefore, be assumed to generalise to other populations
