Believing in the Powers of Mindfulness: A Thematic Narrative Approach and the Development of a New Scale.

Objectives: The beliefs and expectations people bring into mindfulness practice can affect the measurement outcomes of interventions. The aim of this mixed-method study was to examine the key beliefs in the powers of mindfulness-understood as non-judgmental awareness of the present moment-to transform the individual and the society, and to develop and validate the Belief in the Powers of Mindfulness Scale (BPMS). Method: In-depth, semi-structured interviews were conducted with mindfulness meditators (n = 32), including follow-up interviews (n = 22). Qualitative data were analysed through a thematic narrative approach. Participants (n = 458) completed a questionnaire that included the new scale. Results: Participants' key beliefs were thematically analysed in three transformation themes: interpersonal relationships and compassion, peace and violence, and the inner world-themes were encapsulated in the BPMS. Ideas presented in each theme were undergirded by a host of ideologies, epistemic claims, and metaphysical assumptions about the nature of mind, self, and reality-which are predicated by broader cultural trends such as expressive individualism, perennial philosophy, and New Age sentiments and ideals. The BPMS showed strong internal consistency and convergent validity, and individuals who were older and more spiritual practised mindfulness more often and for longer, and self-reported greater mindfulness skills, and scored higher on the BPMS. Conclusions: Findings illustrate the persisting importance of attending to people's beliefs and expectations in mindfulness interventions and further the call for a contextual approach that accounts for cultural factors. The newly developed BPMS may assist with the measuring of peoples' beliefs and expectations.

DEBATE: The inevitable decline of mindfulness.

The use of mindfulness meditation as a well-being and clinical tool is being deeply challenged on various fronts. The recent failure of showing its salutary effects on schoolchildren, in a large-scale study, which stands as the most expensive study in the history of meditation science (£6.4 million), is accompanied by growing evidence of potential adverse effects associated with mindfulness practice. It is suggested that the heightened enthusiasm surrounding the benefits of mindfulness led academics to use facile metaphors to promote it (such as comparing the mind to a muscle) and distorted its presentation - both in disseminating overhyped findings and in neglecting the report of adverse effects.

Individual differences in meditation interventions: A meta-analytic study.

OBJECTIVES: Meditation interventions typically show small to moderate effects on health and well-being, but we know little about how these effects vary across individuals. This meta-analytic study investigates the relationship between baseline participant characteristics and the outcomes of meditation. METHODS: A systematic search yielded 51 eligible studies with 7782 participants. A combination of subgroup analyses and meta-regression based on the random-effects model were used. RESULTS: We found that a higher baseline level of psychopathology or depression was associated with deterioration in mental health after a meditation intervention. On the other hand, participants with higher scores on interpersonal variables, motivation, medical conditions, and mindfulness showed higher levels of positive meditation outcomes. Higher well-being and stress were simultaneously associated with moderate increases in negative and positive meditation outcomes. Participant demographics, psychological traits, self-concept, and length of meditation practice did not significantly influence the response to meditation. CONCLUSIONS: Overall, we found that meditation interventions affect participants differently, and identified some of the individual characteristics that should be considered when using meditation interventions.

The limited prosocial effects of meditation: A systematic review and meta-analysis.

Many individuals believe that meditation has the capacity to not only alleviate mental-illness but to improve prosociality. This article systematically reviewed and meta-analysed the effects of meditation interventions on prosociality in randomized controlled trials of healthy adults. Five types of social behaviours were identified: compassion, empathy, aggression, connectedness and prejudice. Although we found a moderate increase in prosociality following meditation, further analysis indicated that this effect was qualified by two factors: type of prosociality and methodological quality. Meditation interventions had an effect on compassion and empathy, but not on aggression, connectedness or prejudice. We further found that compassion levels only increased under two conditions: when the teacher in the meditation intervention was a co-author in the published study; and when the study employed a passive (waiting list) control group but not an active one. Contrary to popular beliefs that meditation will lead to prosocial changes, the results of this meta-analysis showed that the effects of meditation on prosociality were qualified by the type of prosociality and methodological quality of the study. We conclude by highlighting a number of biases and theoretical problems that need addressing to improve quality of research in this area.

What Is the Molecular Signature of Mind-Body Interventions? A Systematic Review of Gene Expression Changes Induced by Meditation and Related Practices.

There is considerable evidence for the effectiveness of mind-body interventions (MBIs) in improving mental and physical health, but the molecular mechanisms of these benefits remain poorly understood. One hypothesis is that MBIs reverse expression of genes involved in inflammatory reactions that are induced by stress. This systematic review was conducted to examine changes in gene expression that occur after MBIs and to explore how these molecular changes are related to health. We searched PubMed throughout September 2016 to look for studies that have used gene expression analysis in MBIs (i.e., mindfulness, yoga, Tai Chi, Qigong, relaxation response, and breath regulation). Due to the limited quantity of studies, we included both clinical and non-clinical samples with any type of research design. Eighteen relevant studies were retrieved and analyzed. Overall, the studies indicate that these practices are associated with a downregulation of nuclear factor kappa B pathway; this is the opposite of the effects of chronic stress on gene expression and suggests that MBI practices may lead to a reduced risk of inflammation-related diseases. However, it is unclear how the effects of MBIs compare to other healthy interventions such as exercise or nutrition due to the small number of available studies. More research is required to be able to understand the effects of MBIs at the molecular level.

Has the science of mindfulness lost its mind?

The excitement about the application of mindfulness meditation in mental health settings has led to the proliferation of a literature pervaded by a lack of conceptual and methodological self-criticism. In this article we raise two major concerns. First, we consider the range of individual differences within the experience of meditation; although some people may benefit from its practice, others will not be affected in any substantive way, and a number of individuals may suffer moderate to serious adverse effects. Second, we address the insufficient or inconclusive evidence for its benefits, particularly when mindfulness-based interventions are compared with other activities or treatments. We end with suggestions on how to improve the quality of research into mindfulness interventions and outline key issues for clinicians considering referring patients for these interventions.

Preliminary Evidence That Yoga Practice Progressively Improves Mood and Decreases Stress in a Sample of UK Prisoners.

Objectives. In the first randomized controlled trial of yoga on UK prisoners, we previously showed that yoga practice was associated with improved mental wellbeing and cognition. Here, we aimed to assess how class attendance, self-practice, and demographic factors were related to outcome amongst prisoners enrolled in the 10-week yoga intervention. Methods. The data of 55 participants (52 male, 3 female) who completed a 10-week yoga course were analysed. Changes in pre- and postyoga measures of affect, perceived stress, and psychological symptoms were entered into linear regression analyses with bias-corrected and accelerated bootstrap confidence intervals. Class attendance, self-practice, demographic variables, and baseline psychometric variables were included as regressors. Results. Participants who attended more yoga classes and those who engaged in frequent (5 times or more) self-practice reported significantly greater decreases in perceived stress. Decreases in negative affect were also significantly related to high frequency self-practice and greater class attendance at a near-significant level. Age was positively correlated with yoga class attendance, and higher levels of education were associated with greater decreases in negative affect. Conclusions. Our results suggest that there may be progressive beneficial effects of yoga within prison populations and point to subpopulations who may benefit the most from this practice.

Participation in a 10-week course of yoga improves behavioural control and decreases psychological distress in a prison population.

BACKGROUND: Yoga and meditation have been shown to be effective in alleviating symptoms of depression and anxiety in healthy volunteers and psychiatric populations. Recent work has also indicated that yoga can improve cognitive-behavioural performance and control. Although there have been no controlled studies of the effects of yoga in a prison population, we reasoned that yoga could have beneficial effects in a setting where psychosocial functioning is often low, and the frequency of impulsive behaviours is high. METHODS: Participants were recruited from 7 British prisons and randomly allocated to either a 10-week yoga programme (yoga group; 1 class per week; N = 45) or a control group (N = 55). Self-report measures of mood, stress, and psychological distress were collected before and after the intervention period. Participants completed a cognitive-behavioural task (Go/No-Go) at the end of the study, which assessed behavioural response inhibition and sustained attention. RESULTS: Participants in the yoga group showed increased self-reported positive affect, and reduced stress and psychological distress, compared to participants in the control group. Participants who completed the yoga course also showed better performance in the cognitive-behavioural task, making significantly fewer errors of omission in Go trials and fewer errors of commission on No-Go trials, compared to control participants. CONCLUSIONS: Yoga may be effective in improving subjective wellbeing, mental health, and executive functioning within prison populations. This is an important consideration given the consistently high rates of psychological morbidity in this group and the need for effective and economical intervention programmes.
