Mindfulness-Based Interventions for People Experiencing Psychosis: A Randomized Feasibility Study

ObjectivesThere is a rapidly growing body of research into mindfulness-based interventions (MBIs) for People Experiencing Psychosis. This study aimed to examine the feasibility of a novel, 6-week 1:1 MBI, as well as the feasibility of the assessment and analysis of between-session practice and metacognitive beliefs as predictors of Quality of Life (QoL) outcomes.MethodA case series design was used. Eight participants were recruited, with seven completers. The primary outcome, QoL, was assessed up to four times per week, with additional outcomes taken weekly, pre-post, and pre-mid-post. Multilevel modelling was used to examine predictors.ResultsThe methods and intervention were feasible. However, most participants preferred shorter, 30-min appointments with one mindfulness practice. Between-session practice varied significantly (0-220 min total), with three participants completing no between-session practice. Pre- to mid-intervention improvement in metacognitive beliefs was lost at post-intervention assessment. Non-significant trends of improvement were noted in most outcomes.ConclusionsA full-scale trial is recommended to assess the intervention and predictors, with adjustment of intervention length and post-intervention assessment suggested. Future research should also further examine metacognitive processes and factors associated with between-session practice adherence for people experiencing psychosis accessing MBIs.PreregistrationThis study was not preregistered. However, detailed study and intervention protocols were created as part of the ethics application, which was followed throughout the study. These documents are available upon request.
