Does mindfulness improve inhibitory control in psychotic disorders? A randomized controlled clinical trial

Abstract

Background/Objective : Impaired Inhibitory Control (IC) is a core feature of psychotic disorders and is related with impaired social functioning in people experiencing psychosis. Despite research showing the benefits of mindfulness over IC in the general population, no study has assessed its effects on IC in psychoses. The aim of our study was to assess the effectiveness of a mindfulness-based intervention combined with integrated rehabilitation treatment in a sample of people diagnosed of psychotic disorders. Method : Fifty-six patients diagnosed with psychotic disorder were recruited and randomly allocated either to integrated rehabilitation treatment or integrated rehabilitation treatment enhanced with 26 mindfulness group sessions. Measures comprised PANSS interview, MAAS scale, and Stroop Color Word Test (SCWT). The primary outcome variable was the performance in the non-congruent trials of the SCWT. Results : There were no differences between groups at baseline. At post-treatment patients allocated to mindfulness group increased their scores in non-congruent trials of SCWT and in MAAS. At post-treatment mindfulness group scored higher than integrated rehabilitation treatment in MAAS. Conclusions : Data suggest that mindfulness added to integrated rehabilitation treatment may improve IC in psychosis. Results are convergent with prior works about the effect of mindfulness over cognitive performance in general population.

Reducing stress and promoting well-being in healthcare workers using mindfulness-based cognitive therapy for life

“…MBPs teach these foundational skills across the full continuum of wellbeing, from those currently experiencing severe mental health difficulties right through to those who are flourishing ( Crane et al, 2017 , Huppert, 2009 , López-Navarro et al, 2020 , Pardos-Gascón et al, 2021 ). Mindfulness-Based Stress Reduction (MBSR) was developed to help people cope with stress, pain and illness ( Kabat-Zinn, 1990 ) and Mindfulness-Based Cognitive Therapy (MBCT) integrated MBSR and cognitive-behavioural therapy to help people with a history of recurrent depression learn skills to stay well ( Segal et al, 2013 ).…”

The Effects of Mindfulness-Based Intervention on Shooting Performance and Cognitive Functions in Archers

“…EF contains three distinguishable components (e.g., inhibitory control, working memory and cognitive flexibility) (Diamond and Ling, 2016), and the inhibitory control aspect of EF may play a crucial role in fine motor sports (Jacobson and Matthaeus, 2014), because athletes competing in these sports must maintain extremely high levels of concentration on their targets while also ignoring internal and external distractions (Diamond and Ling, 2016). López-Navarro et al (2020) found that a long-term mindfulness exercise integrated with rehabilitation treatment improved inhibitory control in patients with psychotic disorder. Nien et al (2020) further reported that a five weeks MBI improved participant performance on inhibition-related conditions (i.e., the incongruent condition) of the Stroop task and increased the durations at which participants completed an exhaustion running test, suggesting associations among MBI, EF, and sport performance.…”
