Defining and measuring meditation-related adverse effects in mindfulness-based programs

Reflection on the RANZCP position on the adverse effects of psychotherapy

OBJECTIVE

In this perspective, we investigate how the Royal Australian and New Zealand College of Psychiatrists' (RANZCP) position statement on psychotherapy takes the potential for adverse effects into account.

CONCLUSIONS

Psychotherapy has two critical outcomes - efficacy and adverse effects. Evidence-based psychotherapy is significantly more effective than care-as-usual for about one in 10 psychotherapy patients. However, a similar proportion also reports adverse effects. Despite this, the RANZCP position statement on psychotherapy focuses on efficacy with minimal discussion of the adverse effects. This is an oversight because psychiatrists have legal and ethical obligations to consider the adverse effects as well as the benefits of any treatment. We therefore reflect on the RANZCP's six recommendations in light of the adverse effects of psychotherapy.

From Confound to Clinical Tool: Mindfulness and the Observer Effect in Research and Therapy

The observer effect (OE), the idea that observing a phenomenon changes it, has important implications across scientific disciplines involving measurement and observation. While often viewed as a confounding variable to control for, this paper argues that the OE should be seriously accounted for, explored and systematically leveraged in research and clinical settings. Specifically, mindfulness practices that cultivate present-moment, non-judgmental awareness are proposed as a platform to account for, explore and intentionally harness the OE. In research contexts, mindfulness training may allow participants to provide more precise self-reports by minimizing reactive biases that perturb the observed phenomena. Empirical evidence suggests mindfulness enhances interoceptive awareness and reduces automatic judgment, potentially increasing measurement sensitivity, specificity and validity. Clinically, psychotherapies often aim to make unconscious patterns explicitly observable to the client, capitalizing on the transformative potential of observation. Mindfulness directly cultivates this capacity for meta-awareness, allowing individuals to "de-center" from rigid cognitive-emotional patterns fueling psychopathology. Rather than avoiding unpleasant experiences like cravings or anxiety, mindfulness guides individuals to simply observe these phenomena, reducing identification and reactivity. Mindfulness practices may leverage components of the OE, facilitating lasting psychological change. To further study the OE, developing an "Observer Effect Index" to code observer influence is proposed. Overall, this paper highlights the ubiquity of the OE and advocates developing methods to intentionally account for and apply observer influences across research and therapeutic contexts.

Childhood trauma and subclinical PTSD symptoms predict adverse effects and worse outcomes across two mindfulness-based programs for active depression

Within mindfulness-based programs (MBPs), mixed results have been found for the role of childhood trauma as a moderator of depression outcomes. Furthermore, childhood trauma and PTSD symptoms have been identified as possible risk factors for the occurrence of meditation-related adverse effects (MRAE). The present research examined multiple forms of childhood trauma and PTSD symptoms as predictors of depression treatment outcomes and MRAEs. Various forms of childhood trauma (e.g., abuse and neglect) were examined as predictors of depression treatment outcomes and participant attrition using secondary analyses of two MBP clinical trials (N = 52 and 104, respectively). Study 2 also examined meditation-related side effects (MRSE) and MRAE as outcomes and current subclinical and past PTSD symptoms as predictors. Childhood trauma led to worse depression outcomes across both study 1 and study 2, such that total childhood trauma and childhood sexual abuse were significant predictors across both studies. Childhood sexual abuse predicted attrition in study 2. Finally, multiple forms of childhood trauma and PTSD symptoms predicted MRSE, while total childhood trauma, childhood emotional abuse, and subclinical PTSD symptoms predicted lasting MRAE. Childhood trauma and PTSD symptoms may lead to worse outcomes and a greater occurrence of adverse effects within MBPs for active depression. These results call for further trauma-sensitive modifications, safety monitoring, participant screening, and provider education when implementing these programs.

Effectiveness of Digital Mental Health Interventions in the Workplace: Umbrella Review of Systematic Reviews

BACKGROUND

There is potential for digital mental health interventions to provide affordable, efficient, and scalable support to individuals. Digital interventions, including cognitive behavioral therapy, stress management, and mindfulness programs, have shown promise when applied in workplace settings.

OBJECTIVE

The aim of this study is to conduct an umbrella review of systematic reviews in order to critically evaluate, synthesize, and summarize evidence of various digital mental health interventions available within a workplace setting.

METHODS

A systematic search was conducted to identify systematic reviews relating to digital interventions for the workplace, using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis). The review protocol was registered in the Open Science Framework. The following databases were searched: PubMed, Web of Science, MEDLINE, PsycINFO, and Cochrane Library. Data were extracted using a predefined extraction table. To assess the methodological quality of a study, the AMSTAR-2 tool was used to critically appraise systematic reviews of health care interventions.

RESULTS

The literature search resulted in 11,875 records, which was reduced to 14 full-text systematic literature reviews with the use of Covidence to remove duplicates and screen titles and abstracts. The 14 included reviews were published between 2014 and 2023, comprising 9 systematic reviews and 5 systematic reviews and meta-analyses. AMSTAR-2 was used to complete a quality assessment of the reviews, and the results were critically low for 7 literature reviews and low for the other 7 literature reviews. The most common types of digital intervention studied were cognitive behavioral therapy, mindfulness/meditation, and stress management followed by other self-help interventions. Effectiveness of digital interventions was found for many mental health symptoms and conditions in employee populations, such as stress, anxiety, depression, burnout, and psychological well-being. Factors such as type of technology, guidance, recruitment, tailoring, and demographics were found to impact effectiveness.

CONCLUSIONS

This umbrella review aimed to critically evaluate, synthesize, and summarize evidence of various digital mental health interventions available within a workplace setting. Despite the low quality of the reviews, best practice guidelines can be derived from factors that impact the effectiveness of digital interventions in the workplace.

Leveraging meditation research for the study of psychedelic-related adverse effects

Psychedelics have shown early evidence for a range of benefits and low harm profiles in extant research. However, adverse effects (AEs) research in psychedelics has been limited, leading to underspecified AE profiles, inconsistent measurement, and potential undercounting of AEs. The development of safe, effective psychedelic therapies and treatments for AEs when they occur requires a thorough assessment of psychedelic-related AEs, their phenomenology, risk factors, and longitudinal duration. This article proposes that research on meditation-related AEs, which overlap in important ways with the phenomenological and contextual characteristics of psychedelic-related AEs, has engaged many methodological challenges present in the study of psychedelic-related AEs. Thus, meditation-related AE research offers thematic and methodological insights that are valuable to psychedelic AE research. An integrative review of extant AE research in both psychedelics and meditation is provided, and an agenda for leveraging meditation research to advance the investigation of psychedelic AEs is recommended. This includes the utility of meditation-related AEs as a comparator condition for psychedelic-related AEs, as well as recommendations for the adoption of (1) detailed and comprehensive, (2) user-informed, (3) impact-based, (4) standardized, (5) unbiased, and (6) representative measures of AEs and (7) examining factors that influence their impacts and trajectories.

Mindfulness training reduces the preference for proenvironmental outcomes

Theoretical accounts posit that mindfulness promotes proenvironmental behavior. While this claim is supported by correlational findings, past intervention studies provided no evidence that enhancing mindfulness increases self-report measures of proenvironmental behavior. Here, we tested whether a 31-day mindfulness intervention strengthens preferences for proenvironmental outcomes with decision tasks involving real conflict between participants' selfish interests and beneficial consequences for the environment. To unravel the psychological mechanisms underlying the impact of mindfulness on proenvironmental behavior, we assessed the impact of mindfulness training on prosociality and future orientation. Contrary to our hypotheses, the mindfulness intervention reduced instead of increased preferences for proenvironmental and prosocial outcomes, whereas no effects were observed on future orientation. Baseline preferences for proenvironmental and prosocial outcomes (and the intervention effects on them) were correlated, providing empirical evidence for a link between proenvironmental behavior and prosociality. Together, the current data suggest that the relationship between mindfulness and proenvironmental behavior as well as prosociality may be more complicated than assumed in the literature.

Do mindfulness interventions cause harm? Findings from the Learning to Apply Mindfulness to Pain (LAMP) Pragmatic Clinical Trial

BACKGROUND

Although mindfulness-based interventions (MBIs) are widely used in clinical and nonclinical settings, there has been little systematic study of their potential risks. To address this gap, we examined differences in psychological and physical worsening among participants in the usual care and intervention conditions of a 3-group, randomized pragmatic trial (Learning to Apply Mindfulness to Pain [LAMP]) that tested the effectiveness of 2 approaches to delivering MBIs to patients with chronic pain.

METHODS

The sample consisted of 374 male and 334 female patients with chronic pain enrolled in the LAMP trial who completed a 10-week follow-up survey, 61% of whom had a mental health diagnosis. Psychological and physical worsening was assessed by a checklist asking whether participants experienced specific symptoms since beginning the study. We used multivariable logistic regression models with imputed data to determine whether predicted probabilities of increased symptoms differed between usual care and the 2 MBIs.

RESULTS

Participants in usual care were more likely to report experiencing increased psychological and physical worsening than were those in the MBIs, including an increase in disturbing memories; sadness, anxiousness, and fatigue; isolation and loneliness; and feeling more upset than usual when something reminded them of the past.

CONCLUSIONS

MBIs do not appear to cause harm, in terms of increased symptoms, for this population of patients with chronic pain and high levels of mental health comorbidities.

Resilience and distress among adolescents and young adults receiving hematopoietic cell transplantation: The Promoting Resilience in Stress Management randomized trial

BACKGROUND

Adolescents and young adults (AYAs) receiving hematopoietic cell transplantation (HCT) are at high risk of poor psychosocial health. This study aimed to determine whether the Promoting Resilience in Stress Management (PRISM) intervention mitigated these risks during the first 6 months posttransplant.

METHODS

This multisite, parallel, randomized trial was conducted from April 2019 to March 2023. Eligible AYAs were aged 12-24 years, English speaking, and within 1 month of HCT for cancer or cancer predisposition syndrome. They were assigned 1:1 to PRISM (a brief, skills-based intervention targeting "resilience resources" [stress management, goal setting, cognitive reframing, and meaning making]) or usual care (UC). Outcomes included total symptoms of depression and anxiety (Hospital Anxiety and Depression Scale; primary outcome), hope (Snyder Hope Scale), resilience (10-item Connor-Davidson Resilience Scale), and health-related quality of life (HRQOL; Pediatric Quality of Life Inventory Cancer Module). Analyses leveraged multivariable linear regressions; exploratory analyses assessed the influence of baseline depression or anxiety.

RESULTS

Of 94 enrolled and randomized AYAs, the mean age was 16.7 years (SD, 4.2); 43 (46%) were female, 56 (60%) were non-Hispanic White, 22 (23%) were Hispanic, and nine (10%) were Black. Most (77%) had leukemia. Of n = 50 randomized to PRISM and n = 44 to UC, 37 (74%) and 33 (73%) completed all study procedures, respectively. In intention-to-treat analyses, PRISM did not affect 6-month depression and anxiety (β = -1.1; 95% CI, -3.7 to 1.5), hope (β = 0.83; 95% CI, -3.3 to 4.9), resilience (β = -0.01; 95% CI, -3.0 to 3.0), or HRQOL (β = 1.5; 95% CI, -4.7 to 7.9). Among AYAs with preexisting anxiety or depression, PRISM recipients reported greater 6-month improvements in hope (score change, +3.71; SD, 6.9) versus UC recipients (score change, -2.76; SD, 6.5) (p = .04).

CONCLUSIONS

Resilience coaching did not influence outcomes in this sample. Exploratory findings suggest it may be more effective when directed toward those with concurrent distress.

Feasibility, acceptability, and fidelity of remote-delivered abbreviated mindfulness-based cognitive therapy interventions for patients with migraine and depressive symptoms

OBJECTIVE

This study was an open-label single-arm clinical trial evaluating the fidelity, feasibility, acceptability, and clinical signal of abbreviated mindfulness-based cognitive therapy (MBCT-brief) delivered either via telephone (MBCT-T) or by video conferencing (MBCT-V) for people with migraine and comorbid depressive symptoms.

BACKGROUND

Migraine is commonly comorbid with elevated depressive symptoms. MBCT reduces depressive symptoms and shows promise to reduce migraine-related disability. An abbreviated and remotely delivered version of MBCT could increase access to care.

METHODS

People with migraine and elevated depressive symptoms were recruited from a large urban health system. Participants were assigned in blocks of eight to receive an evidence-based MBCT-brief treatment, including eight weekly group classes and home practice delivered via telephone (MBCT-T) or video (MBCT-V); MBCT-T was randomly selected for the first block. Sessions were recorded and coded for treatment fidelity. Feasibility was assessed via session attendance (primary), homework completion, recruitment rate, and survey completion rate. Acceptability was assessed via the eight-item Client Satisfaction Questionnaire (CSQ-8; primary), the Credibility/Expectancy Questionnaire (CEQ), the System Usability Scale (SUS), and items assessing survey acceptability. Participants completed the Headache Disability Inventory (HDI) and Quick Inventory of Depressive Symptomatology-Self Report 16-item (QIDS-SR16) at baseline, mid-treatment, and post-treatment. Feasibility and acceptability rates were compared to a priori benchmarks.

RESULTS

Participants (n = 16) were all female with a mean (standard deviation [SD]) age of 45 (13) years, the majority of whom identified as White (13/16, 81%) and non-Hispanic (14/16, 88%). The intervention met the a priori criteria set for therapist fidelity to treatment protocol (mean [SD] MBCT-Treatment Acceptability and Competence Scale Adherence score 2.9 [0.2]), feasibility (mean [SD] session attendance was 7.9/8 [0.3]), and acceptability (mean [SD] CSQ-8 score 28.8 [3.3]) for the entire sample and for each treatment arm. The usability of the remote-delivery system was high across study participants (mean [SD] SUS score 84.8 [11.0]). Survey procedures were broadly deemed acceptable, with at least 80% participants either endorsing "Agree" or "Strongly Agree" across all items. Using Wilcoxon tests, we observed significant reductions in both the HDI (pre-treatment median [interquartile range] score 63 [40, 70] vs. post-treatment 36 [26, 54], p = 0.004) and the QIDS-SR16 (pre-treatment median [interquartile range] score 8 [5, 13] vs. post-treatment 4 [3, 6], p = 0.003).

CONCLUSION

We found that remotely delivered MBCT-brief for migraine and depressive symptoms was feasible and acceptable to patients in both the telephone and video modalities. Intervention was associated with significant post-treatment reductions in headache-related disability and depressive symptomatology, findings that must be interpreted cautiously in the absence of a control group.

Mindfulness-Based Cognitive Therapy for Individuals Who Are Suicidal: A Randomized Controlled Trial

There is a need for well-described treatments targeting individuals at risk for suicidal behaviors. The present study aims to investigate the effectiveness of MBCT adapted to individuals who are suicidal (MBCT-S) in a randomized controlled trial, comparing an intervention group receiving MBCT-S and treatment as usual (TAU) with a control group receiving TAU only. Participants who were 18 years or older and experienced suicidal ideation were included. Assessments on suicidal ideation and symptoms associated with suicidal behavior were carried out at baseline, post-treatment, and 12 weeks after the end of the training. When comparing the intervention group with the control group, a significant reduction was found at follow-up in suicidal ideation and depressive symptoms. When focusing on the intervention group only, a significant reduction was found in suicidal ideation, depressive symptoms, hopelessness, worrying, defeat, and entrapment, and a significant increase in mindfulness both at post-treatment and at follow-up. The findings suggest that MBCT-S is a promising suicide-specific intervention as it may have the potential to reduce suicidal ideation and suicide-related components.

The effect of mindfulness meditation on depressive symptoms during the COVID-19 pandemic: a systematic review and meta-analysis

Currently, 280 million people worldwide experience depression, ranking it third in the global burden of disease. The incidence of depression has risen due to the COVID-19 pandemic, making it essential to examine evidence-based practices in reducing depressive symptoms during this unprecedented time. This systematic review and meta-analysis aim to analyze randomized controlled trials during the COVID-19 pandemic that evaluated the effect of mindfulness meditation on depressive symptoms in individuals with depression. Four databases (PubMed, Embase, Web of Science, and Scopus) were searched in November 2023 using search terms including meditation, mindfulness, depression, and depressive symptoms. The meta-analysis was conducted using Review Manager 5.4 software (Cochrane Collaboration). A random model and Standard Mean Difference analysis with 95% CIs were used for continuous variables. The systematic review included 26 RCT studies. The meta-analysis showed significant effects of mindfulness meditation interventions (SMD = - 1.14; 95% CI - 1.45 to - 0.83; P < 0.001) in reducing depressive symptoms compared to comparison groups. The findings suggest a positive effect of mindfulness meditation on depressive symptoms in individuals with depression during the COVID-19 pandemic.

Systematic review of the safety of mindfulness-based interventions for psychosis

Harmful outcomes of psychological interventions are under-researched, including in mindfulness-based interventions (MBI) for psychosis. This systematic review summarizes reporting and prevalence of 8 harm indices (death, adverse events, hospitalisation, study drop out, noncompletion of therapy, side effects of therapy, symptom deterioration and crisis service use) in Randomised Controlled Trials (RCTs) of MBIs for psychosis. Meta-analyses of risk differences were also calculated for each harm index. The review included 39 studies, with a total n of 2684 participants across studies. The percentage of studies reporting on each index of harm, and the prevalence of harm, varied greatly across each index. 0% of studies reported on side effects of interventions compared to 92% of studies reporting on study dropout. Meta-analyses of risk differences (RD) found a higher risk of hospitalisation (RD (95% CI) = -0.136 (-0.23 to -0.05), p = 0.003) and crisis service use (RD (95% CI) = -0.160 (-0.299, -0.024), p = 0.02) in control arms compared to intervention arms, and no significant difference in adverse events, death, symptom deterioration, noncompletion of therapy, drop out and side effects of therapy. Overall, reporting of harm was inconsistent across studies and the quality of data collection and reporting varied. MBIs for psychosis appear to be safe and may reduce the risk of hospitalisation and use of crisis services. However, the absence of thorough reporting on harm precludes a balanced analysis of benefits versus harms. Future research into the effectiveness of MBIs should consistently operationalise, monitor and report data on harm.

A framework for assessment of adverse events occurring in psychedelic-assisted therapies

OBJECTIVE

Despite considerable research examining the efficacy of psychedelic-assisted therapies (PATs) for treating psychiatric disorders, assessment of adverse events (AEs) in PAT research has lagged. Current AE reporting standards in PAT trials are poorly calibrated to features of PAT that distinguish it from other treatments, leaving many potential AEs unassessed.

METHODS

A multidisciplinary working group of experts involved in PAT pooled formally and informally documented AEs observed through research experience and published literature. This information was integrated with (a) current standards and practices for AE reporting in pharmacotherapy and psychotherapy trials and (b) published findings documenting post-acute dosing impacts of psychedelics on subjective states, meaning, and psychosocial health variables, to produce a set of AE constructs important to evaluate in PAT as well as recommended methods and time frames for their assessment and monitoring. Correspondence between identified potential AEs and current standards for AE assessment was examined, including the extent of coverage of identified AE constructs by 25 existing measures used in relevant research.

RESULTS

Fifty-four potential AE terms warranting systematized assessment in PAT were identified, defined, and categorized. Existing measures demonstrated substantial gaps in their coverage of identified AE constructs. Recommendations were developed for how to assess PAT AEs (including patient, clinician, and informant reports), and when to assess over preparation, dosing session, integration, and follow-up. Application of this framework is demonstrated in a preliminary assessment protocol (available in the supplement).

CONCLUSIONS

This assessment framework addresses the need to capture post-acute dosing AEs in PAT, accounting for its pharmacotherapy and psychotherapy components, as well as documented impacts of psychedelics on worldviews and spirituality.

Experience of compassion-based practice in mindfulness for health for individuals with persistent pain

Purpose of the Study

Research indicates that acquiring compassion is an integral part to positive outcomes to Mindfulness-based interventions (MBI), yet there is both theoretic and empirical literature suggesting that people with persistent pain are more likely to experience challenges and distress when engaging compassion-based practices. Mindfulness for Health is a standardised MBI for people with persistent pain and health conditions. This study sought to explore the positive, neutral and difficult experiences of compassion-based practice and meditation for participants in Mindfulness for Health to further understand implications and risks for participants of MBI's.

Method and Design

A qualitative design using Interpretative Phenomenological Analysis was applied to explore how participants understood of the experience of compassion-based practice and the meaning they gave to it. Eight participants who had completed the Mindfulness for Health from four separate groups were interviewed about their experience.

Results

Five master themes were identified 'turning away from self-with-pain', 'self-with-pain experienced as shameful', 'facilitating change', 'turning towards self-with-pain', and 'accepting self'. Participants identified both perceived positive changes and difficult emotional experiences during the meditation practice, which they related to the context of compassion in their past and present life.

Conclusions

Developing compassion is an important part of Mindfulness for Health, which is salient for participants as both a challenging and potentially valuable experience. Acquisition of mindfulness skills, supporting group dynamics and modelling compassion are understood as helpful in overcoming personal barriers and challenging experiences. Further research is needed to understand processes involved and explore the experience of non-completers.

The shape of the change: Cumulative and incremental changes in daily mood during mobile-app-supported mindfulness training

Understanding of the exact trajectories of mood improvements during mindfulness practice helps to optimize mindfulness-based interventions. The Mindfulness-to-Meaning model expects mood improvements to be linear, incremental, and cumulative. Our findings align with this expectation. We used multilevel growth curve models to analyze daily changes in positive mood reported by 190 Polish participants during 42 days of a mobile-app-supported, mindfulness-based intervention. The daily positive mood increased among 83.68% of participants. Participants who started the training reported worse mood improved more and faster than participants with better mood at the baseline. Dispositional mindfulness and narcissism - individual difference variables associated with high vs. low emotion regulation ability, respectively - were not associated with mood improvement trajectories. A small group of participants (16.32%) showed a steady decline in positive mood during the intervention. The results underscore the importance of a more comprehensive understanding of individual variability in benefiting from mindfulness-based interventions.

Does it matter how meditation feels? An experience sampling study

OBJECTIVE

Meditation apps are the most widely used mental health apps. The precise mechanisms underlying their effects remain unclear. In particular, the degree to which affect experienced during meditation is associated with outcomes has not been established.

METHOD

We used the meditation app arm of a recently completed randomized controlled trial comparing a self-guided meditation app (Healthy Minds Program) to a waitlist control. Predominantly distressed public school employees (n = 243, 80.9% with clinically elevated depression and/or anxiety) reported positive and negative affect during meditation practice. Data were analyzed using two-level multivariate latent growth curve models (observations nested within participants) that simultaneously attended to both positive and negative affect. We examined whether positive and negative affect during meditation changed over time and whether these changes were associated with changes in psychological distress (parent trial's preregistered primary outcome) at posttest or 3-month follow-up.

RESULTS

On average, participants reported decreased negative affect but no change in positive affect during meditation over time. Increased positive affect and decreased negative affect during meditation were associated with improvements in distress at posttest and follow-up. Change in positive affect was a stronger predictor of distress at follow-up than change in negative affect.

CONCLUSIONS

Despite notions embedded within mainstream mindfulness meditation training that deemphasize the importance of the affective experience of practice (i.e., nonjudgmental awareness of present moment experience, regardless of valence), results indicate that these experiences contain signals associated with outcomes. Monitoring affect during meditation may be worthwhile to guide intervention delivery (i.e., measurement-based care, precision medicine). (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Altered states of consciousness caused by a mindfulness-based programme up to a year later: Results from a randomised controlled trial

BACKGROUND

Mindfulness-based programmes (MBPs) have shown beneficial effects on mental health. There is emerging evidence that MBPs may also be associated with marked deviations in the subjective experience of waking consciousness. We aimed to explore whether MBPs can have a causal role in different types of such states.

METHODS

We conducted a pragmatic randomised controlled trial (ACTRN12615001160527). University of Cambridge students without severe mental illness were randomised to an 8-week MBP plus mental health support as usual (SAU), or to SAU alone. We adapted the Altered States of Consciousness Rating Scale (OAV, 0-100-point range) to assess spontaneous experiences in daily life, and included it as a post-hoc secondary outcome at the end of the one-year follow-up questionnaire. Two-part model analyses compared trial arms, and estimated dose-response effects of formal (meditation) and informal (daily activities) mindfulness practice during the year. Sensitivity analyses correcting for multiple comparisons were conducted.

RESULTS

We randomised 670 participants; 205 (33%) completed the OAV. In comparison with SAU, MBP participants experienced unity more frequently and intensively (two-part marginal effect (ME) = 6.26 OAV scale points, 95% confidence interval (CI) = 2.24, 10.27, p = 0.006, Cohen's d = 0.33) and disembodiment more frequently (ME = 4.84, 95% CI = 0.86, 8.83, p = 0.019, Cohen's d = 0.26). Formal practice predicted spiritual, blissful and unity experiences, insightfulness, disembodiment, and changed meanings. Informal practice predicted unity and blissful experiences. Trial arm comparisons and informal practice effects lost significance after corrections for multiple comparisons, but formal practice dose-response effects remained significant.

CONCLUSIONS

Results provide a novel suggestion of causal links between mindfulness practice and specific altered states of consciousness. To optimise their impact, practitioners and teachers need to anticipate and handle them appropriately. Future studies need to confirm findings and assess mechanisms and clinical implications.

Trajectories of mindfulness, flow experience, and stress during an online-based MBSR program: the moderating role of emotional exhaustion

Introduction

Despite numerous papers focusing on mindfulness at work, our knowledge about how flow experience and stress as indicators of optimal functioning and wellbeing at work evolve over time during the common mindfulness-based stress reduction (MBSR) program remains limited. Drawing from the transactional model of flow and stress, we argue that a build-up of mindfulness over the training duration not only leads to a decrease in stress but also an increase in flow experience. Thereby, we examine the moderating role of emotional exhaustion amplifying the beneficial effects of mindfulness.

Methods

In a quasi-experimental study, 91 participants completed weekly questionnaires over the course of 8 weeks. Forty six participants in the experimental group took part in the MBSR program, while 45 participants were part of an inactive control group.

Results

Mindfulness and flow showed a significant linear increase over time, whereas stress exhibited a linear decrease. Those who participated in the MBSR training reported an increase in mindfulness that positively and negatively predicted the trajectories of flow and stress, respectively. Emotional exhaustion amplified the effects of the trajectory of mindfulness on the trajectories of flow and stress.

Discussion

These findings suggest that mindfulness can not only reduce stress but can also foster the autotelic experience of flow, especially for chronically depleted individuals. However, more research is necessary to replicate these results and address the limitations of the current study, including the quasi-experimental design, the use of self-report measures, as well as the dropout during the study period.

Prevalence and 20-year trends in meditation, yoga, guided imagery and progressive relaxation use among US adults from 2002 to 2022

Meditation, yoga, guided imagery, and progressive relaxation are promoted as complementary approaches for health and wellbeing in the United States, but their uptake by different sociodemographic groups is unclear. This study assessed the prevalence and 20 year trends in the use of these practices in US adults between 2002-2022. We examined practice use and associations with sociodemographic and health factors in a population-weighted analysis of n = 134,959 participants across 5 cycles of the National Health Interview Survey. The overall use of meditation (18.3%, 60.53 million), yoga (16.8%, 55.78 million) and guided imagery/progressive relaxation (6.7%, 22.22 million) increased significantly from 2002 to 2022. Growth was consistent across most sociodemographic and health strata, however users of 'Other' race (comprising 54% Indigenous Americans, Odds Ratios; ORs = 1.28-1.70) and users with moderate (ORs = 1.19-1.29) psychological distress were overrepresented across all practices, and those with severe psychological distress were overrepresented in meditation (OR = 1.33) and guided imagery/progressive relaxation (OR = 1.42). Meditation use has accelerated over time for 65 + year olds (OR = 4.22), people not accessing mental health care (OR = 1.39), and less educated (OR = 4.02) groups, potentially reflecting unmet health needs. Health professionals should consider the extensive use of complementary practices in service and treatment planning and consider their risks and benefits.

10-Week Trajectories of Candidate Psychological Processes Differentially Predict Mental Health Gains from Online Dyadic versus Mindfulness Interventions: A Randomized Clinical Trial

Background: App-based contemplative interventions, such as mindfulness-based interventions, have gained popularity for the promotion of mental health; however, the understanding of underlying intervention-specific mechanisms remains limited, especially related to novel inter-relational dyadic practices. Methods: We tested (n = 253) seven putative mechanisms underlying two brief (daily 12-min) online mental interventions: attention-focused mindfulness and socio-emotional partner-based, both supported by weekly online coaching. Weekly self-reports of rumination, worry, psychological flexibility, affective control, social support, acceptance, and mindfulness were obtained over 10 weeks of intervention, and depression, anxiety, and resilience were assessed as pre- and post-intervention outcomes. Results: Significant week-to-week reductions in rumination and increases in psychological flexibility were observed in both interventions. Only attention-based practice led to temporal reductions in worry, and only socio-emotional dyadic practice led to temporal increases in affective control. Mediation analyses with slopes of weekly variables as mediators detected no significant indirect effects. However, exploratory moderation analyses revealed that intervention-related reductions in depressive symptomatology and anxiety vulnerability and increases in resilience were predicted by weekly increases in acceptance and affective control in the socio-emotional dyadic group, and by weekly reductions in rumination and worry in the mindfulness group. Limitations of the study include reliance on brief self-report measures, relatively small sample size, and absence of long-term follow-up assessments indicating the need for future well-powered longitudinal studies comparing intervention modalities. Conclusions: We present preliminary evidence for practice-specific active ingredients of contemplative interventions, which can be leveraged to enhance their efficiency for mental health.

Effects of a mindfulness-based program on the occupational balance and mental health of university students. Protocol for a randomized controlled trial

OBJECTIVE

The aim is to examine whether the addition of Virtual Reality (VR) meditation training to a standard 8-week Mindfulness-Based Health Care Program (MBHC-VR) results in a significantly increased improvement in occupational, mental health, and psychological functioning versus MBHC-only in university students.

MATERIALS AND METHODS

A randomized controlled clinical trial with three arms (MBHC, MBHC-VR, Control Group), four assessment time points (pre-intervention, inter-session, post-intervention, and 3-month follow-up), and mixed methodology will be proposed. University students (undergraduate, master, or doctoral) interested in participating and who meet the inclusion/exclusion criteria will be included over two years. Data will be collected from different ad hoc questionnaires, several standardized tests, and an Ecological Momentary Assessment. We will use R software to carry out descriptive analyses (univariate and bivariate), multilevel modeling, and structural equation models to respond to the proposed objective. The qualitative analysis will be carried out using the MAXQDA program and the technique of focus groups.

DISCUSSION

It is expected that with the proposed intervention university students will learn to relate in a healthier way with their mental processes, so as to improve their occupational balance (OB) and their psychological well-being.

Recording harms in randomized controlled trials of behavior change interventions: a scoping review and map of the evidence

OBJECTIVES

Randomized controlled trials evaluate diverse interventions. This can include medical interventions such as drugs or surgical procedures, or behavior change interventions (BCIs) that aim to change a habit, belief, or attitude to improve health, for example, healthy eating, psychological wellbeing. Harms are often recorded poorly or inconsistently within randomized controlled trials of BCIs. This scoping review aimed to collate and describe literature on categories, definitions, and mechanisms of harms from BCIs; methods of identifying plausible harms; and recommendations for recording harms.

STUDY DESIGN AND SETTING

A scoping review was conducted. Three databases (MEDLINE, PsycINFO, and CINAHL) were searched. Reference list checking and citation searching were performed. Articles were included if they discussed (1) interventions that aimed to modify behavior, (2) categories or mechanisms of harms, and (3) methods or recommendations for recording harms. All research designs were included. One reviewer reviewed titles, abstracts, and full texts; queries were checked with another reviewer. Data were extracted and synthesized descriptively by one reviewer and checked by another reviewer. A thematic map was constructed to summarize the review findings. Harms described from specific BCIs were identified, and examples were selected and summarized.

RESULTS

The review included 37 articles. Nineteen of 37 articles contributed to a thematic review. Three articles described categories of harms; categories of harm included physical, psychological, group and social interactions, cultural, equity, opportunity cost, environmental, and economic. Seven articles included mechanisms or underlying factors for harms including feelings of failure leading to shame or stigma, and group interventions enabling knowledge exchange on unhealthy behaviors. Twelve articles provided recommendations for recording harms, including taking a proportionate approach by focusing on the most plausible and important harms, collecting different perspectives on whether harms had occurred (eg, caregivers and family members), and using qualitative research methods to identify harms. One article described a three-step method to identify plausible harms from an intervention, and six articles supported aspects of the method. Eighteen of 37 articles contributed to a review which collated harms arising from specific interventions, for example, a peer support intervention in inflammatory bowel disease caused distressing conversations which might lead to anxiety and confrontation with a possible negative future.

CONCLUSION

BCIs can cause harm. This review identified categories and proposed mechanisms of harms, as well as methods and recommendations for identifying and recording harms in BCIs for inclusion in forthcoming recommendations.

Mindfulness Teacher Trainees' Experiences (MTTE): An investigation of intense experiences in mindfulness-based interventions

With the increasing interest in mindfulness practices within clinical as well as non-clinical settings and the increasing body of research on the positive effects of mindfulness, concerns have been raised that mindfulness might also produce adverse effects including intense experiences and psychosis. The aim of this study was to investigate if intense experiences occur as a natural part of mindfulness practice, and if so to examine the characteristics of such experiences. We conducted a qualitative analysis based on fortnightly meditation reports from 13 mindfulness teacher trainees for 4 months. Intense experiences in meditation were frequently expressed in the reports of most of the practitioners and in some individuals these experiences were similar to psychotic-like experiences. This study presents suggestive evidence that mindfulness practices can produce intense experiences and that for some individuals these intense experiences may resemble psychotic-like experiences.

Psilocybin enhances insightfulness in meditation: a perspective on the global topology of brain imaging during meditation

In this study, for the first time, we explored a dataset of functional magnetic resonance images collected during focused attention and open monitoring meditation before and after a five-day psilocybin-assisted meditation retreat using a recently established approach, based on the Mapper algorithm from topological data analysis. After generating subject-specific maps for two groups (psilocybin vs. placebo, 18 subjects/group) of experienced meditators, organizational principles were uncovered using graph topological tools, including the optimal transport (OT) distance, a geometrically rich measure of similarity between brain activity patterns. This revealed characteristics of the topology (i.e. shape) in space (i.e. abstract space of voxels) and time dimension of whole-brain activity patterns during different styles of meditation and psilocybin-induced alterations. Most interestingly, we found that (psilocybin-induced) positive derealization, which fosters insightfulness specifically when accompanied by enhanced open-monitoring meditation, was linked to the OT distance between open-monitoring and resting state. Our findings suggest that enhanced meta-awareness through meditation practice in experienced meditators combined with potential psilocybin-induced positive alterations in perception mediate insightfulness. Together, these findings provide a novel perspective on meditation and psychedelics that may reveal potential novel brain markers for positive synergistic effects between mindfulness practices and psilocybin.

The effects of mindfulness-based interventions in medical students: a systematic review

The number of studies on the effects of mindfulness on healthcare professionals is increasing. The main aim of this study was to collate the quantitative results of original studies analyzing the effects of mindfulness-based interventions on a variety of outcomes in medical students. We also analyzed how the study design and characteristics of the intervention affect the results, and identified qualitative effects of mindfulness interventions. A literature search was performed in different databases in June 2020. Original articles meeting the following criteria were included: (1) at least 50% of the participants were medical students, (2) included a mindfulness intervention, (3) analyzed any outcome relating to mindfulness intervention, (4) peer-reviewed (5) written in English. Eventually, 31 articles including 24 different samples were included. Over half of the studies were RCTs. In over half of the studies, the intervention was 4- to 10-week original Mindfulness-Based Stress Reduction or Mindfulness-Based Cognitive Therapy or a modification of these. In general, satisfaction with the interventions was good. Based on a meta-analysis, after the intervention, the intervention group had statistically significantly fewer symptoms of stress and distress and had higher mindfulness than the controls. The beneficial effects persisted in follow-ups over months or years. Both long and shorter courses and courses with and without face-to-face sessions were effective. Both controlled and uncontrolled studies had statistically significant results. Qualitative results revealed potential factors behind the quantitative effects. The number of studies on mindfulness interventions in medical students has increased drastically. Mindfulness-based interventions seem to offer a good possibility to enhance medical students' well-being.

Differentiating mindfulness-integrated cognitive behavior therapy and mindfulness-based cognitive therapy clinically: the why, how, and what of evidence-based practice

It is important to be able to differentiate mindfulness-based programs in terms of their model, therapeutic elements, and supporting evidence. This article compares mindfulness-based cognitive therapy (MBCT), developed for relapse prevention in depression, and mindfulness-integrated cognitive behavior therapy (MiCBT), developed for transdiagnostic applications, on: (1) origins, context and theoretical rationale (why), (2) program structure, practice and, professional training (how), and (3) evidence (what). While both approaches incorporate behavior change methods, MBCT encourages behavioral activation, whereas MiCBT includes various exposure procedures to reduce avoidance, including a protocol to practice equanimity during problematic interpersonal interactions, and a compassion training to prevent relapse. MBCT has a substantial research base, including multiple systematic reviews and meta-analyses. It is an endorsed preventative treatment for depressive relapse in several clinical guidelines, but its single disorder approach might be regarded as a limitation in many health service settings. MiCBT has a promising evidence base and potential to make a valuable contribution to psychological treatment through its transdiagnostic applicability but has not yet been considered in clinical guidelines. While greater attention to later stage dissemination and implementation research is recommended for MBCT, more high quality RCTs and systematic reviews are needed to develop the evidence base for MiCBT.

Mindfulness-based stress reduction for autistic adults: A feasibility study in an outpatient context

LAY ABSTRACT

Autistic adults report high stress levels and difficulties dealing with everyday stressors. Mindfulness-based stress reduction groups aim to help regulate stress responses. We asked 50 autistic adults, without intellectual disability, to participate in a study of mindfulness-based stress reduction. The group program was made accessible through clear group leader communication and good program predictability, as well as reduced exposure to disturbing sensory stimuli. The mindfulness and yoga based exercises from the original mindfulness-based stress reduction program were included. The participants were positive and would even recommend an autistic friend to participate in a mindfulness-based stress reduction group. They reported that mindfulness-based stress reduction could lower symptoms of stress and improved stress coping. We still need to investigate these effects further in larger studies. The findings of this work show that mindfulness-based stress reduction groups can be adapted for autistic adults and that the participants overall were positive to the intervention and the group format.

Effects of a mindfulness-based groupwork program on adolescents in a children's home

Mindfulness means being in the present, intentionally and without any judgment. Mindfulness helps people cope with challenging experiences such as trauma. Children's Homes in Türkiye are institutions that provide social care to young people with past traumatic experiences. This study aims at evaluating the effects of a mindfulness-based (MB) groupwork program with a group of residents in a Children's Home. An experimental pretest-posttest control group design was used. An eight-session MB training program was implemented with 21 female adolescents. There were 29 female adolescents in the control group. The MB groupwork program significantly increased the mindfulness levels of the group. However, its effect on the other variables could not be determined at a significant level. There were positive correlations between mindfulness, life satisfaction and subjective happiness, and a negative correlation with perceived stress. The results of this study showed that MB interventions increase mindfulness levels of adolescents in a Children's Home setting in Türkiye. Secondly, as mindfulness increased, life satisfaction and subjective happiness also increased while perceived stress decreased. MB interventions are recommended to be used in social work interventions with different groups since it can contribute to subjective well-being.

Cognitive Behavioral Therapy and Mindfulness-Based Cognitive Therapy for Depressive Disorders: Enhancing Access and Tailoring Interventions in Diverse Settings

Depressive disorders are an enormous societal burden given their high prevalence and impact on all facets of being human (e.g., relationships, emotions, motivation). There is a variety of evidence-based psychological treatments, with cognitive behavioral therapy (CBT) being the gold standard for major depression. Research has shown that mindfulness-based interventions (MBIs) such as mindfulness-based cognitive therapy (MBCT) are an effective relapse prevention and treatment for depression and that MBIs can be integrated in individual therapy. Furthermore, various delivery modes (e.g., digital-delivered therapy) and settings are offered to best meet different needs and improve accessibility: Evidence suggests that therapist-guided digital CBT, blended therapy, and, to some degree, digitalized MBIs may be an efficacious supplement to traditional face-to-face therapy. This chapter provides an overview of the principles and evidence base for CBT and MBCT as well as different delivery modes for depressive disorders in adults. Finally, chances and challenges of integration are discussed as implications for practice, as well as recommendations and ideas for future research.

A compassion-based treatment for couples with the female partner suffering from current depressive disorder: A randomized-controlled trial

BACKGROUND

Studies have shown that depression and interpersonal relationships are interdependently connected and that including the intimate partner in treatment for depression has beneficial effects. Given evidence that compassion is both an interpersonal quality and a promising treatment target, the goal of this study was to examine the effects of a compassion-based, contemplative treatment for couples employing a multi-method approach for evaluation.

METHODS

In a pre-post-follow-up design, n = 53 different-sex couples including women with current depression were randomly assigned to a 10-week-long CBCT®-fC (Cognitively-Based Compassion Training/intervention for couples) or treatment-as-usual (TAU) condition. Multi-level linear regression models and post-hoc contrasts were calculated to determine changes in depressive symptoms, mindfulness and self-compassion, interpersonal functioning and neuroendocrine markers collected during a partnership appreciation task (PAT) in the laboratory before and after CBCT-fC treatment.

RESULTS

While CBCT-fC led to a comparable decrease of depressive symptoms as TAU, the training specifically increased self-compassion and mindfulness versus TAU. Interestingly, interpersonal functioning did not improve, which was also reflected in participants' preferred self-focus in-between-session practices, instead of practices with interpersonal focus. There were no group-specific changes in psychobiological stress-marker reactivity.

CONCLUSIONS

CBCT-fC was effective in decreasing current depressive symptomatology and increasing mindfulness, and self-compassion. Especially the motivation to participate, such as improving interpersonal functioning, should be addressed and intrinsic motives of the partners to be involved. In highly burdened individuals, self-regulation may need to be improved before co-regulation can be addressed, which would requiring longer treatments. Facilitating factors for engaging in the practice between-sessions seem meaningful.

Epigenetic, psychological, and EEG changes after a 1-week retreat based on mindfulness and compassion for stress reduction in healthy adults: Study protocol of a cross-over randomized controlled trial

INTRODUCTION

The main objective of the study will be to evaluate the effects of two widely used standardized mindfulness-based programs [Mindfulness-Based Stress Reduction (MBSR) and Compassion Cultivation Training (CCT)], on epigenetic, neurobiological, psychological, and physiological variables.

METHODS

The programs will be offered in an intensive retreat format in a general population sample of healthy volunteer adults. During a 7-day retreat, participants will receive MBSR and CCT in a crossover design where participants complete both programs in random order. After finishing their first 3-day training with one of the two programs, participants will be assigned to the second 3-day training with the second program. The effects of the MBSR and CCT programs, and their combination, will be measured by epigenetic changes (i.e., DNA methylation biomarkers), neurobiological and psychophysiological measures (i.e., EEG resting state, EKG, respiration patterns, and diurnal cortisol slopes), self-report questionnaires belonging to different psychological domains (i.e., mindfulness, compassion, well-being, distress, and general functioning), and stress tasks (i.e., an Arithmetic Stress Test and the retrieval of negative autobiographical memories). These measures will be collected from both groups on the mornings of day 1 (pre-program), day 4 (after finishing the first program and before beginning the second program), and day 7 (post-second program). We will conduct a 3-month and a 12-month follow-up using only the set of self-report measures.

DISCUSSION

This study aims to shed light on the neurobiological and psychological mechanisms linked to meditation and compassion in the general population. The protocol was registered at clinicaltrials.gov (Identifier: NCT05516355; August 23, 2022).

Assessing the Potential Risks of Digital Therapeutics (DTX): The DTX Risk Assessment Canvas

MOTIVATION

Digital therapeutics (DTX), i.e., health interventions that are provided through digital means, are increasingly available for use; in some countries, physicians can even prescribe selected DTX following a reimbursement by health insurances. This results in an increasing need for methodologies to consider and monitor DTX's negative consequences, their risks to patient safety, and possible adverse events. However, it is completely unknown which aspects should be subject to surveillance given the missing experiences with the tools and their negative impacts.

OBJECTIVE

Our aim is to develop a tool-the DTX Risk Assessment Canvas-that enables researchers, developers, and practitioners to reflect on the negative consequences of DTX in a participatory process.

METHOD

Taking the well-established business model canvas as a starting point, we identified relevant aspects to be considered in a risk assessment of a DTX. The aspects or building blocks of the canvas were constructed in a two-way process: first, we defined the aspects relevant for discussing and reflecting on how a DTX might bring negative consequences and risks for its users by considering ISO/TS 82304-2, the scientific literature, and by reviewing existing DTX and their listed adverse effects. The resulting aspects were grouped into thematic blocks and the canvas was created. Second, six experts in health informatics and mental health provided feedback and tested the understandability of the initial canvas by individually applying it to a DTX of their choice. Based on their feedback, the canvas was modified.

RESULTS

The DTX Risk Assessment Canvas is organized into 15 thematic blocks which are in turn grouped into three thematic groups considering the DTX itself, the users of the DTX, and the effects of the DTX. For each thematic block, questions have been formulated to guide the user of the canvas in reflecting on the single aspects. Conclusions: The DTX Risk Assessment Canvas is a tool to reflect the negative consequences and risks of a DTX by discussing different thematic blocks that together constitute a comprehensive interpretation of a DTX regarding possible risks. Applied during the DTX design and development phase, it can help in implementing countermeasures for mitigation or means for their monitoring.

Mindfulness-based stress reduction is linked with an improved Cognitive Reflection Test score

Initially, dual-process theories suggested that the existence of two different cognitive systems explained why many participants do not find the correct answer in many reasoning tasks. The Cognitive Reflection Test (CRT) is one such task. It contains three questions with incorrect answers (typically associated with intuition and thus system 1 which processes information automatically) and correct answers (typically associated with deliberate thinking and thus system 2 which involves the conscious processing of information). More recent theories suggest system 1 is responsible for both incorrect and correct responses, with system 2 being used to resolve the conflict between these different intuitions. Since mindfulness training improves self-regulation and cognitive flexibility, we believe it could improve CRT scores by reducing the relative weight of initial intuitions by strengthening alternative intuitions, thus increasing the probability of triggering deliberate reasoning. To test this hypothesis, we recruited 36 participants, all registered in the same Mindfulness-Based Stress Reduction (MBSR) training. Of those 36 participants, 18 answered the CRT before the training and 18 answered it after 8 weeks of training. Results show that participants who followed MBSR training had better CRT scores than those without training. This is coherent with our hypothesis that mindfulness training could reduce the relative weight of initial intuitions and facilitate deliberate thinking.

Containing Attachment Concerns: Does Trait Mindfulness Buffer the Links between Attachment Insecurity and Maladaptive Sexual Motivations?

Individuals reporting greater insecure attachment are more likely to report maladaptive sexual motivations, such as sex to avoid negative relational and personal outcomes (e.g., conflict). Despite the costs of such sexual motivations, research is less clear regarding what might buffer the extent to which attachment insecurities manifest in such motives. The current study examined whether trait mindfulness moderates the links between attachment insecurity and maladaptive sexual motives. Participants (N = 194) completed measures of trait mindfulness, general sexual motivations, and attachment. As predicted, the links between attachment anxiety and having sex to cope and affirm the self were eliminated among individuals reporting higher levels of the acting with awareness facet of trait mindfulness. No such buffering effects were seen for attachment avoidance. Instead, acting with awareness mindfulness appeared to increase the extent to which more avoidantly attached individuals reported coping and self-affirmation-based sexual motives. These findings contribute to knowledge regarding the potential utility and limits of mindfulness in relational and sexual contexts, perhaps suggesting that mindfulness may help anxiously attached individuals manage the extent to which attachment concerns manifest in maladaptive sexual motivations. Findings of the study may inform both theory regarding mindfulness in interpersonal functioning and how mindfulness interventions might be deployed in sex therapy contexts.

Impact of warm mindfulness on emotion regulation: A randomized controlled effectiveness trial

OBJECTIVE

To determine the effects of mindfulness training for primary care (MTPC), an integrated warm mindfulness training program, on emotion regulation and its relationship with health behavior change. Interventions that improve self-regulation, particularly emotion regulation, are needed for the self-management of comorbid chronic physical and mental illnesses. Mindfulness-based interventions (MBIs) may impact self-regulation and facilitate health behavior change.

METHOD

A randomized controlled comparative effectiveness trial was conducted in a population of adult primary care patients to evaluate the impact of MTPC versus a low-dose mindfulness comparator (LDC) on self-reported difficulties in emotion regulation (DERS) total score and other assays of self-regulation at baseline, Weeks 8 and 24. Self-reported action plan initiation was reported between Weeks 8 and 10. Participants had diagnoses of anxiety, depression, or stress-related disorders. MTPC is an 8-week insurance-reimbursable warm MBI designed to cultivate mindfulness and self-compassion and to catalyze chronic illness self-management related health behavior change.

RESULTS

Compared to LDC, MTPC participants had statistically significant reductions in DERS total score at 8 weeks (d = -0.59, β = -12.98, 95% CI [-23.3 to -2.6]; p = .01) and 24 weeks (d = -0.61, β = -13.35, [-24.3, -2.4]; p = .02). Compared to 38% for LDC, 63% of MTPC participants successfully initiated their action plan within 3 weeks (OR = 2.87, [1.1, 7.9]; p = .04).

CONCLUSIONS

This randomized controlled trial demonstrated MTPC enhanced emotion regulation and facilitated initiation of chronic illness self-management and health behavior change among primary care patients with anxiety, depression, and stress-related disorders, replicating previous reports.

The effect of universal school-based mindfulness on anhedonia and emotional distress and its underlying mechanisms: A cluster randomised controlled trial via experience sampling in secondary schools

This cluster randomised controlled trial examined the effectiveness of universal school-based mindfulness training (MT; vs. passive control) to lower anhedonia and emotional distress among mid-adolescents (15-18 years). It further examined three potential mechanisms: dampening of positive emotions, non-acceptance/suppression of negative emotions, and perceived social pressure not to experience/express negative emotions. Adolescents (ncontrol = 136, nintervention = 95) participated in three assessment points (before, after and two/three months after the in-class MT), consisting of Experience Sampling (ES) assessments and self-report questionnaires (SRQs) to corroborate the ES assessments. Analyses were based on general linear modelling and multilevel modelling. Overall, no evidence was found for a significant beneficial and long-lasting impact of the MT on adolescents' mental health. Importantly, some barriers inherently linked to universal MT approaches (low engagement in and mixed attitudes towards the MT) may have tempered the effectiveness of the MT in the current trial. Further research should prioritise overcoming these barriers to optimise programme implementation. Additionally, given the potential complex interplay of moderators at micro- (home practice), meso- (school climate), and macro-level (broader context), research should simultaneously focus on alternative ways of delivering MT at schools to strengthen adolescents' mental health.

History repeating: guidelines to address common problems in psychedelic science

Research in the last decade has expressed considerable optimism about the clinical potential of psychedelics for the treatment of mental disorders. This optimism is reflected in an increase in research papers, investments by pharmaceutical companies, patents, media coverage, as well as political and legislative changes. However, psychedelic science is facing serious challenges that threaten the validity of core findings and raise doubt regarding clinical efficacy and safety. In this paper, we introduce the 10 most pressing challenges, grouped into easy, moderate, and hard problems. We show how these problems threaten internal validity (treatment effects are due to factors unrelated to the treatment), external validity (lack of generalizability), construct validity (unclear working mechanism), or statistical conclusion validity (conclusions do not follow from the data and methods). These problems tend to co-occur in psychedelic studies, limiting conclusions that can be drawn about the safety and efficacy of psychedelic therapy. We provide a roadmap for tackling these challenges and share a checklist that researchers, journalists, funders, policymakers, and other stakeholders can use to assess the quality of psychedelic science. Addressing today's problems is necessary to find out whether the optimism regarding the therapeutic potential of psychedelics has been warranted and to avoid history repeating itself.

Meditation, mindfulness, and acceptance methods in psychotherapy: A systematic review

OBJECTIVE

: Meditation, mindfulness, and acceptance (MMA) methods have gained popularity among psychotherapists and the public. The impact of these strategies as implemented in treatment packages (e.g., mindfulness-based interventions) has been studied extensively. However, the impact of integrating MMA strategies into individual psychotherapy has not been established.

METHODS

: To address this gap in the literature, we conducted a systematic review of empirical (quantitative or qualitative) studies investigating the use of MMA methods during individual psychotherapy in adult samples.

RESULTS

: After reviewing 4671 references, only three studies (one quantitative, two qualitative) met our inclusion criteria. The one experimental study (n = 162) provided no evidence that including mindfulness meditation improved outcomes beyond other active interventions (ds = 0.00-0.12 for effects on general clinical symptoms vs. progressive muscle relaxation and treatment-as-usual, respectively). Two qualitative studies (n = 5 therapist-patient dyads in one study, n = 9 adults in one study) provided preliminary evidence that patients may find MMA methods helpful.

CONCLUSIONS

: We highlight future directions for work in this area, including clarifying optimal dosage and timing, identifying patient characteristics associated with beneficial or adverse effects, investigating cultural adaptations, and clarifying how MMA constructs can be measured within individual psychotherapy. We conclude by highlighting training recommendations and therapeutic practices.

Individual participant data systematic review and meta-analysis of randomised controlled trials assessing adult mindfulness-based programmes for mental health promotion in non-clinical settings

Introduction

Mindfulness-based programmes (MBPs) are widely used to prevent mental ill-health that is becoming the leading global cause of morbidity. Evidence suggests beneficial average effects but wide variability. We aimed to confirm the effect of MBPs on psychological distress, and to understand whether and how baseline distress, gender, age, education, and dispositional mindfulness modify the effect of MBPs on distress among adults in non-clinical settings.

Methods

We conducted a pre-registered systematic review and individual participant data (IPD) meta-analysis (PROSPERO CRD42020200117). Thirteen databases were searched in December 2020 for randomised controlled trials satisfying a quality threshold and comparing in-person, expert-defined MBPs in non-clinical settings with passive control groups. Two researchers independently selected, extracted, and appraised trials using the revised Cochrane Risk-of-Bias Tool (RoB2). Anonymised IPD of eligible trials were sought from collaborating authors. The primary outcome was psychological distress (unpleasant mental or emotional experiences including anxiety and depression) at 1 to 6 months after programme completion. Data were checked and imputed if missing. Pairwise, random-effects, two-stage IPD meta-analyses were conducted. Effect modification analyses followed a within-studies approach. Public and professional stakeholders were involved in the planning, conduct and dissemination of this study.

Results

Fifteen trials were eligible, 13 trialists shared IPD (2,371 participants representing 8 countries, median age 34 years-old, 71% women, moderately distressed on average, 20% missing outcome data). In comparison with passive control groups, MBPs reduced average distress between one- and six-months post-intervention with a small to moderate effect size (standardised mean difference (SMD) -0.32; 95% confidence interval (CI) -0.41 to -0.24; p-value < 0.001; 95% prediction interval (PI) -0.41 to -0.24 (no heterogeneity)). Results were robust to sensitivity analyses, and similar for the other psychological distress time point ranges. Confidence in the primary outcome result is high. We found no clear indication that this effect is modified by baseline psychological distress, gender, age, education level, or dispositional mindfulness.

Conclusions

Group-based teacher-led MBPs generally reduce psychological distress among community adults who volunteer to receive this type of intervention. More research is needed to identify sources of variability in outcomes at an individual level.

Altered states of leadership: mindfulness meditation, psychedelic use, and leadership development

Background

Previous research suggests that mindfulness meditation and psychedelic substances show promise as mental health interventions, but relatively little remains known about their potential impact on leadership outcomes.

Aims

This study aimed to investigate if and how mindfulness meditation and psychedelic use may impact leadership among respondents with a management position as their primary role at work.

Methods

Using samples representative of the US and UK adult populations with regard to sex, age, and ethnicity, this study used quantitative and qualitative methods to examine if and how mindfulness meditation and psychedelic use may impact leadership.

Results

Among respondents with a management position as their primary role at work (n = 3,150), 1,373 reported having tried mindfulness meditation and 559 reported having tried psychedelics. In covariate-adjusted regression analyses, both lifetime number of hours of mindfulness meditation practice and greater psychological insight during respondents' most intense psychedelic experience were associated with describing a positive impact on leadership (ORs = 2.33, 3.49; ps < 0.001), while qualitative analyses revealed nuances in the type of impacts mindfulness meditation and psychedelic use had on leadership. There were several subthemes (e.g., focus, creativity, patience, empathy, compassion) that were frequently reported with both mindfulness meditation and psychedelic use. There were also unique subthemes that were more commonly reported with mindfulness meditation (e.g., improved sleep, stress reduction, calming effects) and psychedelic use (e.g., greater self-understanding, less hierarchical attitudes toward colleagues, positive changes in interpersonal attitudes and behaviors), respectively.

Conclusion

Although causality cannot be inferred due to the research design, the findings in this study suggest potential complementary effects of mindfulness meditation and psychedelic use on leadership, which could inspire new approaches in leadership development.

Moderators and mediators of change of an internet-based mindfulness intervention for college students: secondary analysis from a randomized controlled trial

Background

Existing evidence suggests internet- and mobile-based interventions (IMIs) improve depressive symptoms in college students effectively. However, there is far less knowledge about the potential mechanisms of change of mindfulness-based IMIs, which could contribute to optimizing target groups and interventions. Hence, within this secondary analysis of data from a randomized controlled trial (RCT), potential moderators and mediators of the effectiveness of the IMI StudiCare Mindfulness were investigated.

Methods

Moderation and mediation analyses were based on secondary data from a RCT that examined the effectiveness of the 7-module IMI StudiCare Mindfulness in a sample of college students (intervention group: n = 217; waitlist control group: n = 127). Assessments were collected before (t0; baseline), 4 weeks after (t1; during intervention), and 8 weeks after (t2; post-intervention) randomization. Longitudinal mediation analyses using structural equation modeling were employed, with depressive symptom severity as the dependent variable. For moderation analyses, bilinear interaction models were calculated with depressive symptom severity and mindfulness at t2 as dependent variables. All data-analyses were performed on an intention-to-treat basis.

Results

Mediation analyses showed a significant, full mediation of the intervention effect on depressive symptom severity through mindfulness (indirect effect, a*b = 0.153, p < 0.01). Only the number of semesters (interaction: β = 0.24, p = 0.035) was found to moderate the intervention's effectiveness on depressive symptom severity at t2, and only baseline mindfulness (interaction: β = -0.20, p = 0.047) and baseline self-efficacy (interaction: β = -0.27, p = 0.012) were found to be significant moderators of the intervention effect on mindfulness at t2.

Conclusion

Our results suggest a mediating role of mindfulness. Moderation analyses demonstrated that the intervention improved depressive symptom severity and mindfulness independent of most examined baseline characteristics. Future confirmatory trials will need to support these findings.

Clinical Trial Registration

The trial was registered a priori at the WHO International Clinical Trials Registry Platform via the German Clinical Studies Trial Register (TRN: DRKS00014774; registration date: 18 May 2018).

Strong Mind, Strong Body: The Promise of Mind-Body Interventions to Address Growing Mental Health Needs Among Youth

As the prevalence of childhood and adolescent anxiety, depression, and other mental health concerns continues to rise, there has been an unprecedented increase in support of mind-body practices like yoga, dance, meditation, mindfulness, aerobic exercise, and more-in part driven by the mental health burden imposed by the COVID-19 pandemic. While a growing body of evidence supports the safety and effectiveness of mind-body approaches, gaps in funding for and empirical research on mechanistic underpinnings, methodology development to assess multi-component therapeutic practices, dissemination and implementation, and diversity in researchers, practitioners, and recipients remain. As a consequence, the neurobiological impacts of mind-body techniques are not well understood nor broadly accepted as standard forms of care by clinicians and insurers-often being considered as 'alternative' rather than 'complementary' or 'integrative'. In this commentary, we summarize work from our labs and others highlighting the promise of mind-body approaches for improving mental health in youth, in line with the National Institute of Mental Health's strategic plan to address health disparities. We offer a potential framework for implementation and research-the Expressive Therapies Continuum. We also propose solutions to key research and policy gaps, that by could have positive public health impacts for those who are struggling and to prevent emergence of psychiatric illness, especially in developing youth.

Cessations of consciousness in meditation: Advancing a scientific understanding of nirodha samāpatti

Absence of consciousness can occur due to a concussion, anesthetization, intoxication, epileptic seizure, or other fainting/syncope episode caused by lack of blood flow to the brain. However, some meditation practitioners also report that it is possible to undergo a total absence of consciousness during meditation, lasting up to 7 days, and that these "cessations" can be consistently induced. One form of extended cessation (i.e., nirodha samāpatti) is thought to be different from sleep because practitioners are said to be completely impervious to external stimulation. That is, they cannot be 'woken up' from the cessation state as one might be from a dream. Cessations are also associated with the absence of any time experience or tiredness, and are said to involve a stiff rather than a relaxed body. Emergence from meditation-induced cessations is said to have profound effects on subsequent cognition and experience (e.g., resulting in a sudden sense of clarity, openness, and possibly insights). In this paper, we briefly outline the historical context for cessation events, present preliminary data from two labs, set a research agenda for their study, and provide an initial framework for understanding what meditation induced cessation may reveal about the mind and brain. We conclude by integrating these so-called nirodha and nirodha samāpatti experiences-as they are known in classical Buddhism-into current cognitive-neurocomputational and active inference frameworks of meditation.

Current Practices, Experiences, and Views in Clinical Hypnosis: Findings of an International Survey

An online survey of 691 clinicians who use hypnosis was conducted in 31 countries to gain a broad real-world picture of current practices, views, and experiences in clinical hypnosis. Among 36 common clinical uses, stress reduction, wellbeing and self-esteem-enhancement, surgery preparations, anxiety interventions, mindfulness facilitation, and labor and childbirth applications were the most frequently rated as highly effective (each by ≥70% of raters) in the clinicians' own experience. Adverse hypnosis-associated effects had been encountered by 55% of clinicians but were generally short-lived and very rarely judged as serious. The most common hypnosis approaches used were Ericksonian (71%), hypnotic relaxation therapy (55%), and traditional hypnosis (50%). Almost all respondents reported regularly using other therapeutic modalities alongside hypnosis. Among a range of client variables potentially affecting therapy, most clinicians rated hypnotist-client rapport (88%) and client motivation (75%) as very or extremely important factors for successful hypnotherapy. The majority of respondents had conducted hypnosis treatment via teletherapy, and 54% of those estimated it to be as effective as in-person treatment.

Restructuring insight: An integrative review of insight in problem-solving, meditation, psychotherapy, delusions and psychedelics

Occasionally, a solution or idea arrives as a sudden understanding - an insight. Insight has been considered an "extra" ingredient of creative thinking and problem-solving. Here we propose that insight is central in seemingly distinct areas of research. Drawing on literature from a variety of fields, we show that besides being commonly studied in problem-solving literature, insight is also a core component in psychotherapy and meditation, a key process underlying the emergence of delusions in schizophrenia, and a factor in the therapeutic effects of psychedelics. In each case, we discuss the event of insight and its prerequisites and consequences. We review evidence for the commonalities and differences between the fields and discuss their relevance for capturing the essence of the insight phenomenon. The goal of this integrative review is to bridge the gap between the different views and inspire interdisciplinary research efforts for understanding this central process of human cognition.

A Three-Armed Randomized Controlled Trial to Evaluate the Effectiveness, Acceptance, and Negative Effects of StudiCare Mindfulness, an Internet- and Mobile-Based Intervention for College Students with No and "On Demand" Guidance

The college years can be accompanied by mental distress. Internet- and mobile-based interventions (IMIs) have the potential to improve mental health but adherence is problematic. Psychological guidance might promote adherence but is resource intensive. In this three-armed randomized controlled trial, "guidance on demand" (GoD) and unguided (UG) adherence-promoting versions of the seven-module IMI StudiCare Mindfulness were compared with a waitlist control group and each other. The GoD participants could ask for guidance as needed. A total of 387 students with moderate/low mindfulness were recruited. Follow-up assessments took place after 1 (t1), 2 (t2), and 6 (t3) months. Post-intervention (t2), both versions significantly improved the primary outcome of mindfulness (d = 0.91-1.06, 95% CI 0.66-1.32) and most other mental health outcomes (d = 0.25-0.69, 95% CI 0.00-0.94) compared with WL, with effects generally persisting after 6 months. Exploratory comparisons between UG and GoD were mostly non-significant. Adherence was low but significantly higher in GoD (39%) vs. UG (28%) at the 6-month follow-up. Across versions, 15% of participants experienced negative effects, which were mostly mild. Both versions effectively promoted mental health in college students. Overall, GoD was not associated with substantial gains in effectiveness or adherence compared with UG. Future studies should investigate persuasive design to improve adherence.

Mindful attention promotes control of brain network dynamics for self-regulation and discontinues the past from the present

Mindful attention is characterized by acknowledging the present experience as a transient mental event. Early stages of mindfulness practice may require greater neural effort for later efficiency. Early effort may self-regulate behavior and focalize the present, but this understanding lacks a computational explanation. Here we used network control theory as a model of how external control inputs-operationalizing effort-distribute changes in neural activity evoked during mindful attention across the white matter network. We hypothesized that individuals with greater network controllability, thereby efficiently distributing control inputs, effectively self-regulate behavior. We further hypothesized that brain regions that utilize greater control input exhibit shorter intrinsic timescales of neural activity. Shorter timescales characterize quickly discontinuing past processing to focalize the present. We tested these hypotheses in a randomized controlled study that primed participants to either mindfully respond or naturally react to alcohol cues during fMRI and administered text reminders and measurements of alcohol consumption during 4 wk postscan. We found that participants with greater network controllability moderated alcohol consumption. Mindful regulation of alcohol cues, compared to one's own natural reactions, reduced craving, but craving did not differ from the baseline group. Mindful regulation of alcohol cues, compared to the natural reactions of the baseline group, involved more-effortful control of neural dynamics across cognitive control and attention subnetworks. This effort persisted in the natural reactions of the mindful group compared to the baseline group. More-effortful neural states had shorter timescales than less effortful states, offering an explanation for how mindful attention promotes being present.

Benefits and harms of interventions to improve anxiety, depression, and other mental health outcomes for autistic people: A systematic review and network meta-analysis of randomised controlled trials

LAY ABSTRACT

Nearly three out of four autistic people experience mental health problems such as stress, anxiety or depression. The research already done does not guide us on how best to prevent or treat mental health problems for autistic people. Our aim was to look at the benefits and harms of different interventions on mental health outcomes in autistic people. We searched all the published randomised controlled trials (RCTs) about interventions for mental health conditions in autistic people until 17 October 2020. We also searched for RCTs that were not published in peer-reviewed journals. These were obtained from registers of clinical trials online. We then combined the information from all these trials using advanced statistical methods to analyse how good the interventions are. Seventy-one studies (3630 participants) provided information for this research. The studies reported how participants were responding to the intervention for only a short period of time. The trials did not report which interventions worked for people with intellectual disability. In people without intellectual disability, some forms of cognitive behavioural therapy and mindfulness therapy may be helpful. However, further research is necessary. Many trials used medications to target core features of autism rather than targeting mental health conditions, but these medications did not help autistic people. Until we have more evidence, treatment of mental health conditions in autistic people should follow the evidence available for non-autistic people. We plan to widely disseminate the findings to healthcare professionals through medical journals and conferences and contact other groups representing autistic people.
