Mindfulness in severe and persistent mental illness: a systematic review.

OBJECTIVE: This systematic review summarises the current state of research on mindfulness in SPMI, given the pressing need to provide alternative, scalable and cost-effective treatment modalities for patients with severe and persistent mental illness (SPMI). METHODS: Articles included mindfulness-based interventions for SPMI. Excluded articles included qualitative studies, acceptance and compassion therapies, case reports and reviews. Studies were identified by searching the databases Medline, Embase and PsycINFO. RESULTS: Six randomised controlled trials, seven prospective studies and one retrospective study were identified. Clinical improvements were observed on psychotic symptoms, and on improvements of depression symptoms, cognition, mindfulness, psycho-social and vocational factors. CONCLUSIONS: Findings suggest that mindfulness is feasible for individuals with SPMI, and displays potential benefits in outcomes aside from psychotic symptoms. The effects of mindfulness in psychotic symptoms needs further investigation in larger definitive studies using methodological rigor and thorough assessments of other psychiatric populations who are also representative of SPMI.

Tolerability and suitability of brief group mindfulness-oriented interventions in psychiatric inpatients: a pilot study.

OBJECTIVE: Mindfulness-oriented therapies have a positive impact on patients' overall well-being and alleviate many psychiatric conditions. However, little is known about their use in people with severe mental illness. We aimed to identify which clinical and sociodemographic factors are associated with suitability/tolerability of a brief group mindfulness-oriented therapy. METHODS: This retrospective study examines pre-/post-data from 40 psychiatric inpatients who underwent one session of a 10-min mindfulness-oriented group intervention between January and March 2014. The main outcome was 'suitability for and tolerating the brief mindfulness-oriented group intervention'. We assessed potential correlates of the main outcome, including female gender, shorter hospitalisation, the absence of psychosis and good pre-morbid functioning. RESULTS: The intervention was well tolerated (92.5%) and 50% of patients met both of our relatively stringent suitability and tolerability criteria. Sociodemographic and clinical variables were not associated with suitability/tolerability. Tai chi was the most suitable/tolerable compared to body scan and mindful eating (76.5% vs. 35.7% vs. 22.2%, Fisher's exact p = 0.01, Bonferroni p < 0.05). CONCLUSIONS: Brief group mindfulness therapy interventions are very well tolerated and often suitable for acutely hospitalised psychiatric inpatients, including those with acute psychosis. Mindfulness-oriented intervention with an active component (e.g., tai chi, mindful walking) may potentially be best suited for this population.
