Abstract

Context: Paranoia embodies altered representation of the social environment, fuelling altered feelings of social acceptance leading to further mistrust. Mindfulness-based cognitive therapy (MBCT) may relieve paranoia and reduce its impact on social acceptance. Objective: To determine whether MBCT alters momentary feeling of paranoia and social acceptance in daily life. Design: Randomized controlled trial of daily-life repeated measures (up to 120 per participant) before and after allocation to MBCT or waiting list control. Participants: Volunteer sample of 130 eligible men and women with residual affective dysregulation after at least one episode of major depressive disorder. Interventions: Eight weeks of MBCT in groups of 10-15 participants in addition to participants' usual treatment. Outcome Measures: Daily-life ratings of paranoia and social acceptance. This manuscript concerns additional analyses of the original trial; hypotheses were developed after data collection (focus initially on depressive symptoms) but before data analysis. Results: Sixty-six participants were assigned to the waiting list control group and 64 to the MBCT intervention group, of whom 66 and 61 respectively were included in the per-protocol analyses. Intention-to-treat analyses revealed a significant group by time interaction in the model of momentary paranoia (b = -.18, p
