Mindfulness, acceptance, and emotion regulation: perspectives from Monitor and Acceptance Theory (MAT)

The associations and effects of mindfulness on anger and aggression: A meta-analytic review

Dispositional mindfulness and mindfulness-based interventions have been linked to emotion regulation and may reduce anger and aggression. The present set of four meta-analyses examined and quantified correlational relationships between trait mindfulness, trait anger, and trait aggression, as well as the effects of experimental mindfulness-based interventions on anger and aggression. These meta-analyses contained data from 118 correlational (dispositional mindfulness) and experimental (mindfulness-based intervention) studies. For the subset of self-report correlational studies (kanger = 243, kaggression = 286), we found small-to-medium inverse relationships between dispositional mindfulness and both anger (r = -0.23, p < .001) and aggression (r = -0.19, p < .001). For experimental studies (kanger = 95, kaggression = 38), we found medium effects. Specifically, mindfulness-based interventions produced lower anger (d = -0.48, p < .001) and aggression (d = -0.61, p < .001) relative to the control groups. In sum, results suggest that mindfulness can curb angry and aggressive responses. Effect sizes for the interventions were largest in Asia. Studies with passive versus active control groups showed larger effect sizes. Effect sizes were largely equivalent for all populations studied (e.g., clinical, forensic, healthy adults, medical, students). Our meta-analytic findings suggest that mindfulness training may aid the effective regulation of anger and aggression for diverse populations. They also highlight the need for more rigorous control groups in future research.

Development of a Brief Online Mindfulness-Based Intervention to Reduce Patient Anxiety Before a First-Time Screening Colonoscopy

To describe the development of an online mindfulness-based intervention (MBI) to reduce anxiety before a first-time screening colonoscopy among average-risk patients. A qualitative study used an iterative process guided by health behavior and mindfulness theories and feedback from a convenience sample of patients, endoscopy medical staff, and community members. Patient and medical staff (n = 18) were included in formative interviews (30-45 min), eight helped during intervention development sessions (15-90 min), and four community members reviewed the MBI in individual sessions (60 min). Interviews and sessions were recorded, transcribed verbatim, and analyzed using NVivo qualitative data software. Two themes emerged from the study: (1) both patients and medical staff reported that average-risk patients have pre-procedural anxiety before a first-time screening colonoscopy, and (2) using stakeholder-engaged strategies in an iterative process with both patients and medical staff is important so the developed intervention is acceptable to the priority population and to ensure medical accuracy and avoid disruption of workflow. Using an iterative process with key stakeholders is essential to develop interventions that are feasible and acceptable. The MBI developed through this process is being compared to usual care in a pilot randomized controlled trial to determine intervention feasibility and patient acceptability and to collect preliminary efficacy data. If efficacious, the developed MBI has the potential to reduce pre-procedural anxiety which may improve patient behaviors (e.g., bowel prep adherence and quality), patient satisfaction, and clinic workflow by reducing cancellation/no-shows, the amount of sedation required, and procedural time.

Implementation of Mindfulness-Based Emotion Regulation Strategies: A Systematic Review and Meta-analysis

Among the strategies people can use to regulate their emotions, there is increasing interest in mindfulness. Although prior reviews support that mindful acceptance (equanimity) is an effective strategy, other components of mindfulness (monitoring/ mindful awareness) have received less attention. Further, a recent theoretical framework-the Dual-mode Model of Mindful Emotion Regulation-proposed that mindfulness has two "modes" of action in emotion regulation: (1) implementation to regulate emotions as time-limited strategies and (2) acting as a moderator that facilitates effective emotion regulation. The present systematic review and meta-analysis aimed to evaluate the implementation of mindfulness-based strategies and facilitation effects of mindfulness on emotion reactivity and strategy implementation. A total of 2037 records were screened, from which 110 studies with 767 effects (N = 8,105) were analyzed. There was a significant effect of mindfulness-based strategies (g = .28, 95% CI [.18, .38], I 2 = 83.3%). Components of monitoring (g = .17, 95% CI [.02, .32]) and equanimity (g = .3, 95% CI [.19, .41]) were also effective, although monitoring alone was significantly less effective than other strategies. The effect size was greater for within-subjects designs, text-based emotional stimuli, personally relevant stimuli, and behavioral outcomes (e.g., pain tolerance). Despite small-study effects and publication bias, the estimate was robust to sensitivity analyses (between .15 and .3). Meta-regression of facilitation supported that greater study-level equanimity was associated with reduced reactivity. As hypothesized, mindfulness-based strategies can effectively regulate emotions. Methodological considerations and directions for future study are discussed.

Breath-Counting Task Enhances the Sensitivity of Fear Acquisition

Fear acquisition is an essential survival mechanism for humans; however, the role and mechanisms of mindfulness training in this process remain unclear. This study employed a discriminative fear conditioning paradigm to investigate the effects and mechanisms of short-term mindfulness training, exemplified by the breath-counting task, on fear acquisition. The experiment consisted of three consecutive phases: intervention, habituation, and acquisition. During the intervention phase, each participant was assigned to one of two conditions: the breath-counting task group (experimental group) or the free reading group (control group). The results indicated that the mindfulness group exhibited significantly lower expectancy ratings for shocks to the CS- compared to the control group, while no significant difference was found in the shock ratings for CS+. Regarding skin conductance responses, although the mindfulness group showed a significantly reduced fear response to CS relative to the free reading group, there was no significant difference in overall fear acquisition effects between the two groups. The above findings indicate that breath-counting tasks enhance sensitivity to the acquisition of conditioned fear by reducing exaggerated fear responses to safety signals. The conclusions of this study further elucidate the conflicting results regarding the effects of mindfulness training on fear acquisition and provide novel perspectives for the prevention of anxiety spectrum disorders.

Engagement and Disengagement: From the Basic Science of Emotion Regulation to an Anxiety Spectrum

Emotion regulation strategies vary in depth of processing. For instance, reappraisal requires greater engagement than distraction. This affects short-term and long-term response to stimuli. In this review, I describe how the "engagement-disengagement dimension" improves understanding of emotion regulation in normative contexts and in internalizing psychopathology. Part 1 reviews work from my laboratory and others, suggesting that relatively disengaged emotion regulation strategies (e.g., distraction), may have short-term benefits (e.g., faster implementation), but may come with long-term costs (e.g., increased processing of stimuli at subsequent encounter). Therefore, depending on the desired outcome, the adaptive selection of an emotion regulation strategy will be determined by extent of emotional engagement-disengagement. In Part 2, I describe how individuals with more comorbid internalizing psychopathology (e.g., multiple anxiety and depressive diagnoses) are characterized by disengagement from negative stimuli as measured by the late positive potential (LPP). In addition, I introduce a brain profile I have termed, HARM-A (heightened "alarm" and reduced motivated attention), which is characterized by a combination of heightened "alarm" (i.e., increased amygdala) and emotional disengagement (i.e., blunted LPPs) in response to negative stimuli. HARM-A prospectively predicts worse outcomes over 2 years in a mixed internalizing sample. As such, chronic disengagement from negative stimuli appears to contribute to more comorbid and more severe internalizing psychopathology. Overall, emotional disengagement can be beneficial in the short term but may be poorly suited to emotional coping in the longer term.

Executive function, limbic circuit dynamics and repetitive and restricted behaviors in children with autism spectrum disorder

Objective

Repetitive and restricted behaviors (RRBs) are a core symptom of autism spectrum disorder (ASD), but effective treatment approaches are still lacking. Executive function (EF) has been identified as a promising target, as research increasingly shows a link between EF deficits and the occurrence of RRBs. However, the neural mechanisms that connect the two remain unclear. Since the orbitofrontal cortex (OFC) plays a role in both EF and RRBs, its functional connectivity dynamics could offer valuable insights into this relationship.

Methods

This study analyzed data from the Autism Brain Imaging Data Exchange (ABIDE) II database to explore brain function in 93 boys with ASD and 110 typically developing (TD) boys. Time-varying functional connectivity was analyzed between eight OFC subregions and other brain areas. By employing linear regression, the study assessed how atypical connectivity dynamics and EF influence RRBs. Additionally, mediation analysis with bootstrapping was used to determine how EF mediates the relationship between atypical connectivity and RRBs.

Results

We found significant differences in the variance of FC between ASD and TD groups, specifically in the OFC subregion in L-prefrontal and the left amygdala (t = 5.00, FDR q < 0.01). Regression analyses revealed that increased variance of this FC and EF significantly impacted RRBs, with inhibition, emotional control, and monitor showing strong associations (standardized β = 0.60 to 0.62, p < 0.01), which also had significant indirect effects on the relationship between the above dynamic FC and RRBs, which accounted for 59% of the total effect.

Conclusion

This study highlights the critical role of EFs as a key mechanism in addressing RRBs in ASD. Specifically, it points out that EFs mediate the influence of atypical time-varying interactions within the OFC-amygdala circuit on RRBs.

Understanding the Relationship Between Trait Mindfulness and Perceived Stress: The Serial Multiple Mediating Roles of Basic Psychological Needs Satisfaction and Psychological Flexibility

Although research suggests that trait mindfulness has been negatively associated with perceived stress, an integrative examination of the underlying mechanisms is lacking. Consequently, the purpose of this study was to establish an integrative model within Monitor and Acceptance Theory (MAT). This model examined the relationship between trait mindfulness and perceived stress by assessing two important psychological resources: basic psychological needs satisfaction (BPNS) and psychological flexibility. A total of 679 young adults (Mage = 19.27 years, SD = 1.06) participated in this research. They completed a set of standardized instruments that assessed trait mindfulness, BPNS, psychological flexibility, and perceived stress. Serial multiple mediation analyses showed that trait mindfulness was associated with higher levels of BPNS and psychological flexibility, which in turn were associated with less perceived stress. Furthermore, the path coefficient of the serial multiple mediation was higher than other pathways. These findings demonstrate that BPNS and psychological flexibility are important mechanisms that underlie the relationship between trait mindfulness and perceived stress, particularly when they are synergistic.

Examining interrelations among trajectories of mindful awareness, acceptance, and values-consistent actions in acceptance-based behavioral therapy for generalized anxiety disorder

The goal of this study was to understand how mindful awareness, acceptance, and values-consistent action change across acceptance-based behavioral therapy (ABBT) for generalized anxiety disorder (GAD) and determine their effect on symptoms. We examined weekly data from 31 individuals who received ABBT as part of a randomized control trial for individuals with GAD (Hayes-Skelton, Roemer, & Orsillo, 2013). Participants answered questions weekly about three components of ABBT, including the percentages of time they spent over their past week: 1) aware of the present moment, 2) accepting of their internal experiences, and 3) engaging in values. GAD symptoms were examined using two self-report measures (DASS-21 Stress subscale and PSWQ) and two clinician-rated interview measures (CSR and SIGH-A) at pre- and post-treatment.1 Mindful awareness, acceptance, and values-consistent action increased linearly across ABBT. All three change trajectories were positively correlated (Z's 2.99 to 8.74, p's < .001). Mindful awareness, acceptance, and values-consistent action across treatment predicted decreases in GAD symptoms above and beyond baseline for most outcome measures (Z's -1.95 to -3.03, p's < .05), with the exception that mindfulness did not predict DASS-stress (Z = -1.39, p = .17). These findings are consistent with the structure and model of ABBT.

The mindful resiliency in recovery model: empowering the transcendence of stigma

Introduction

Mindfulness-based interventions show unique promise in treating substance use disorders among marginalized populations who face heightened stigma. The Mindful Resiliency in Recovery Model is introduced as a novel theoretical framework articulating how mindfulness training can mitigate the adverse effects of stigma, enhance psychological resilience, and facilitate sustained recovery from addiction.

Methods

The current manuscript synthesizes various models of mindfulness processes, stigma, and substance use disorder recovery to propose an integrated theoretical framework on the promise of mindfulness-based interventions in supporting recovery. Further, the current manuscript draws upon empirical literature to establish preliminary support for the premises and hypotheses of the Mindful Resiliency in Recovery Model concerning the mechanisms influencing the efficacy of mindfulness-based interventions among marginalized individuals.

Results

Preliminary evidence supports the premises of the proposed model. There is evidence to suggest that specific processes like increased present-moment awareness, acceptance, decentering, reappraisal, and savoring may be especially salient in mitigating internalized stigma and fostering resiliency in recovery. There is a need for additional research on these processes, and contextual factors that may moderate their efficacy.

Discussion

The Mindful Resiliency in Recovery Model has significant implications for optimizing mindfulness-based interventions to empower marginalized individuals to transcend stigma and actualize their capacity for wellbeing in substance use disorder recovery. It provides a roadmap for future research on the mechanisms and contextual factors affecting the efficacy of mindfulness-based interventions for marginalized and stigmatized communities. It further offers guidance to clinicians utilizing mindfulness-based interventions to support individuals experiencing stigma.

Strategies and goals in Emotion Regulation models: a systematic review

Introduction

Studies examining the role of Emotion Regulation (ER) do not consistently explain the underlying model or theory they are employing, resulting in a conflation of different strategies and goals within the ER scientific literature. This study aims to conduct a systematic review and conceptual analysis of the primary strategies and goals advocated in the ER models, theories, and frameworks. Furthermore, we explored the distinctions between the prevailing contemporary ER models and classical conceptions of emotional dynamics, such as those proposed by Aristotle, Descartes, and Darwin.

Methods

An electronic search was conducted in the Web of Science, Medline, and Scopus databases in November 2023. The key search terms used were grouped into two different topics: Emotion Regulation and Models/Theories/Frameworks. Articles were included if they reported one or more ER model in healthy individuals or emotionally disordered individuals and if they were published in a peer-reviewed journal in English in the last 5 years (from 2019 to 2023). A total of two reviewers independently assessed the titles, abstracts, and full texts. Models identified were summarized and classified based on the different ER strategies and goals.

Results

Of the 1,012 titles for initial consideration, 139 articles met the full eligibility criteria and were included for data extraction and synthesis. The review identified 10 ER models, and the most commonly used were the Process Model of Emotion Regulation and the Difficulties in Emotion Regulation. There was a great deal of homogeneity among the proposed ER strategies and goals: the cognitive dimension is the core of ER strategy, and the ER goals are primarily hedonic or instrumental in nature.

Discussion

Both Descartes and Darwin views were present in the ER models; however, some of the most significant contributions in Aristotelian proposal seem to be forgotten, such as the integration of the physical, operational, and growth dimensions (eudaimonic goals).

Psychological mechanisms and neural correlates of trait mindfulness in emotion regulation: Testing a novel approach to the monitor and acceptance theory

Background

The ongoing mental health crisis warrants investigations to understand why trait mindfulness is associated with beneficial mental health outcomes. This study examined attention monitoring and acceptance as psychological mechanisms underlying the relationship between trait mindfulness and emotion regulation and connectivity between the dorsolateral prefrontal cortex (dlPFC) and posterior cingulate cortex (PCC) as a potential neural mechanism.

Methods

A cross-sectional study was conducted with 501 adult participants (age range: 17-79, M = 31, SD = 11.3) representing the general population. To assess emotion regulation and trait mindfulness, participants completed the Difficulties in Emotion Regulation Scale (DERS) and Five Facets Mindfulness Questionnaire (FFMQ). Resting-state functional MRI was acquired in a subsample of 20 participants to explore the role of dlPFC-PCC functional connectivity.

Results

Higher levels of acceptance, as measured using the Non-judging and Non-reactivity subscales of the FFMQ, were significantly associated with fewer overall emotion regulation difficulties and predicted all emotion regulation subscales. In contrast, higher levels of attention monitoring, measured using the Observe subscale, predicted only three DERS subscales and with mixed effects: higher emotional awareness and clarity, but greater difficulties in goal-directed behaviour. The interaction between monitoring and acceptance was not significant, and no correlation was found between these variables and dlPFC-PCC functional connectivity.

Conclusions

These findings challenge previous theories that argue that attention monitoring is crucial for effective emotion regulation. Instead, we conclude that acceptance is the key psychological mechanism, indicating that the traditional focus on attention monitoring in mindfulness training may be less effective than a primary emphasis on acceptance. This study provides a critical review of past research, highlighting issues with operationalising acceptance, and offers recommendations for future studies and practical implications for developing mindfulness interventions.

Mindfulness to enhance quality of life and support advance care planning: a pilot randomized controlled trial for adults with advanced cancer and their family caregivers

BACKGROUND

Patients with advanced cancer and family caregivers often use avoidant coping strategies, such as delaying advance care planning discussions, which contribute to deterioration in their quality of life. Mindfulness-based interventions have shown promise in improving quality of life in this population but have rarely been applied to advance care planning. This pilot trial examined the preliminary efficacy of a group-based Mindfulness to Enhance Quality of Life and Support Advance Care Planning (MEANING) intervention for patient-caregiver dyads coping with advanced cancer. Primary outcomes were patient and caregiver quality of life or well-being, and secondary outcomes included patient advanced care planning engagement (self-efficacy and readiness) and other psychological and symptom outcomes.

METHODS

In this pilot trial, dyads coping with advanced cancer were recruited from five oncology clinics in the midwestern U.S. and randomized to six weekly group sessions of a mindfulness intervention (n = 33 dyads) or usual care (n = 22 dyads). Outcomes were assessed via surveys at baseline, post-intervention, and 1 month post-intervention. All available data were included in the multilevel models assessing intervention efficacy.

RESULTS

Patients in the MEANING condition experienced significant increases in existential well-being and self-efficacy for advance care planning across follow-ups, whereas usual care patients did not. Other group differences in outcomes were not statistically significant. These outcomes included other facets of patient well-being, caregiver quality of life, patient readiness for advance care planning, caregiver burden, and patient and caregiver depressive symptoms, anxiety, sleep disturbance, cognitive avoidance, and peaceful acceptance of cancer. However, only MEANING patients showed moderate increases in psychological well-being across follow-ups, and MEANING caregivers showed moderate increases in quality of life at 1-month follow-up. Certain psychological outcomes, such as caregiver burden at 1-month follow-up, also showed moderate improvement in the MEANING condition. Patients in both conditions reported small to moderate increases in readiness to engage in advance care planning.

CONCLUSIONS

A mindfulness-based intervention showed promise in improving quality-of-life and advance care planning outcomes in patients and caregivers coping with advanced cancer and warrants further testing.

Effects of mindfulness-based stress reduction therapy for sleep quality and perceived stress in patients with spinal cord injury

OBJECTIVE

To explore the effect of the mindfulness-based stress reduction (MBSR) practice on sleep quality and perceived stress in patients with spinal cord injury (SCI).

METHOD

A total of 104 patients with SCI (diagnosed via imaging and clinical symptoms) admitted to our hospital between January 2020 and December 2022 were selected as the study participants. The patients were randomly divided into two groups: the MBSR (observation) group and the control group. The observation group received MBSR therapy and routine nursing, and the control group received music training therapy and routine nursing. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality, and the perceived stress score was used to evaluate stress experienced by the patients at three timepoints: before intervention, 4 weeks and 8weeks after intervention.

RESULTS

Compared with before intervention, the PSQI scores of both the control group and intervention group participants significantly decreased after intervention(P < 0.01). Compared with the 4 weeks after intervention, the PSQI scores of both groups of participants decreased in the 8 weeks after intervention(P < 0.01). There was a significant difference in PSQI scores between the two groups of participants at 4 and 8 weeks after intervention(P < 0.01). Compared with before intervention, the average perceived stress score of both the control group and intervention group participants significantly decreased after intervention(P < 0.05). Compared with the 4 weeks after intervention, the average perceived stress score of both groups of participants decreased in the 8 weeks after intervention(P < 0.01). There was a significant difference in average perceived stress score between the two groups of participants at 4(P < 0.05) and 8 weeks(P < 0.01) after intervention(P < 0.01).

CONCLUSION

The use of MBSR therapy could effectively improve patient sleep quality and reduce perceived stress.

Financial Mindfulness: A Scale

The concept of mindfulness has enjoyed much resonance among researchers. Despite this past work, we argue there is a need for a domain-specific conceptualization and measure of financial mindfulness (FM). We first define FM as "the tendency to be highly aware of one's current objective financial state while possessing an acceptance of that state," and, second, develop and validate an eight-item scale to measure individual differences in FM. This article has nine studies, including a field survey administered by a financial services provider to examine actual behavior. Importantly, the FM-Scale is associated with financial behaviors (i.e., sunk cost bias) above and beyond related scales (i.e., money management stress, self-control, and general mindfulness). To the best of our knowledge, our work is the first to provide a succinct way to measure FM that incorporates elements of both awareness and acceptance, highlighting the role of financial acceptance specifically.

A brief nonattachment intervention based on the three marks of existence: development, rationale, and initial evidence

BACKGROUND

The practices described in Buddhist philosophy are essentially a suite of non-theistic cognitive and behavioral interventions designed to induce nonattachment (N-A), which can be defined in terms of the absence of a need for one's personal reality to be other than it is. Although meditative practices have received attention in multiple literatures, the cognitive analogs to these behaviorally-oriented practices have not.

DESIGN

Two experiments involving undergraduate participants (total N = 239; M age = 19.04) investigated whether the provision of wisdom related to the Three Marks of Existence (i.e., some degree of suffering is inevitable, there is impermanence, and many events are not in our control) could result in (1) higher nonattachment attitudes, (2) lower threat appraisals, (3) lower stressor reactivity, and (4) shorter emotion reaction durations.

RESULTS

With moderate to large effect sizes, the Three Marks trainings (relative to placebo or control conditions) resulted in (1) higher nonattachment attitudes, (2) lower threat appraisals, (3) no differences in negative emotional intensity, but 4) shorter emotion durations.

CONCLUSIONS

These results provide preliminary evidence that enduring cognitive trainings such as the Three Marks can be an effective tool to increase acceptance-related attitudes while attenuating negative reactivity.

Aspects of acceptance: building a shared conceptual understanding

Many contemplatives, scientists, and clinicians have pointed to the value of responding to life's difficulties by accepting experiences as they are. A growing body of research also suggests that acceptance contributes to effective coping with adversity, reduced stress, and improved emotional well-being. Yet within the scientific literature, there is little consensus on what acceptance means or how it should be measured. This makes it nearly impossible to synthesize empirical work on acceptance into a cohesive scientific understanding. Our goal in this paper is to clarify four facets of acceptance that are commonly referenced in research: acknowledging, allowing, non-judging, and non-attachment. We do not propose a specific definition of acceptance or even a set of privileged facets that must be included in future frameworks. We instead offer a vocabulary to facilitate productive communication among researchers that will, in turn, enable a more definitive scientific understanding of this important construct to emerge. After defining and explaining these aspects of acceptance, we further clarify these constructs in two ways. First, we illustrate how the four aspects are dissociable from one another. Second, we analyze their correspondence to related constructs from Acceptance and Commitment Therapy (ACT). Finally, we provide a concept worksheet that scholars can utilize to precisely operationalize acceptance in their own work.

Gender Differences in Negative Life Events, Present-Moment Awareness, Problem-Solving, and Perceived Stress Among Rural Adolescents

Drawing on the stressor-perception-coping-response model of stress, this study examined the associations between negative life events, present-moment awareness, problem-solving, and perceived stress among rural adolescents, focusing specifically on gender differences. Using a cross-sectional design, 3519 Chinese rural adolescents completed measures assessing negative life events, present-moment awareness, problem-solving, and perceived stress. Structural equation modeling was employed to examine the hypothesized serial mediation model. The results revealed a positive association between negative life events and perceived stress in rural adolescents, which was serially mediated by present-moment awareness and problem-solving. Furthermore, significant gender differences were observed. Specifically, girls exhibited larger effects than boys in the overall effect of negative life events on perceived stress, the indirect effect of present-moment awareness, and the serial mediating effect. These findings suggest that present-moment awareness and problem-solving may serve as crucial mechanisms for understanding rural adolescents' perceived stress in response to negative life events, particularly among female rural adolescents.

Examining aspects of psychological flexibility within the integrated motivational-volitional model of suicidal behavior: A prospective investigation

BACKGROUND

According to the integrated motivational-volitional model of suicide, feelings of entrapment are related to the emergence of suicidal ideation (SI). However, this relation can be moderated by certain protective factors.

METHODS

This study examined whether aspects of psychological flexibility (i.e., experiential avoidance, experiential acceptance, harnessing) moderated the relation between aspects of entrapment and SI severity in college students experiencing SI (N = 553) both cross-sectionally and when SI severity was measured 1 week later (N = 247).

RESULTS

At baseline, experiential acceptance, but not experiential avoidance or harnessing, significantly moderated the relation between external entrapment and SI severity and internal entrapment and SI severity. No aspects of psychological flexibility prospectively moderated relations between entrapment and SI severity.

CONCLUSIONS

Aspects of psychological flexibility may influence immediate vulnerability to SI severity among young adults experiencing feelings of entrapment. Implications for clinical interventions influencing changes in psychological flexibility are discussed.

The Role of Attentional Control in Mindfulness Intervention for Emotional Distress: A Randomized Controlled Trial With Longitudinal Mediation Analyses

OBJECTIVE

This study aimed to investigate whether attentional control serves as a mediator for mindfulness-based interventions for emotional distress, utilizing a randomized waitlist (WL)-controlled design.

METHODS

A total of 498 participants with high emotional distress was recruited online and randomly assigned to a 49-day online Mindfulness Intervention for Emotional Distress (MIED) group (N = 249) or a WL control group (N = 249). Levels of attentional control, anxiety and depression were assessed at baseline (T0), Week 3 (T3), Week 5 (T5) and Week 7 (postintervention, T7).

RESULTS

Linear mixed models revealed significant Group-by-Time interaction effects for attentional control (p < 0.001), anxiety (p < 0.001) and depression (p < 0.05). Latent growth curve analyses demonstrated a significant increase in attentional control and a decrease in anxiety and depression levels during the MIED programme. These changes becoming evident starting Week 3. Longitudinal mediation analyses revealed that the slope of attentional control significantly mediated the effects of the MIED programme on the slope of anxiety and depression levels. Further, attentional control level at Week 3 significantly mediates the effect of MIED programme on anxiety and depression levels at Weeks 5 and 7. Similarly, attentional control level at Week 5 significantly mediates the MIED programme's effects on anxiety and depression levels at Week 7.

CONCLUSIONS

The present trial provides evidence suggesting that mindfulness interventions may alleviate emotional distress through the enhancement of attentional control.

Testing the Efficacy of a Brief, Self-Guided Mindfulness Ecological Momentary Intervention on Emotion Regulation and Self-Compassion in Social Anxiety Disorder: Randomized Controlled Trial

BACKGROUND

Theories propose that brief, mobile, self-guided mindfulness ecological momentary interventions (MEMIs) could enhance emotion regulation (ER) and self-compassion. Such changes are posited to be mechanisms of change. However, rigorous tests of these theories have not been conducted.

OBJECTIVE

In this assessor-blinded, parallel-group randomized controlled trial, we aimed to test these theories in social anxiety disorder (SAD).

METHODS

Participants with SAD (defined as having a prerandomization cut-off score ≥20 on the Social Phobia Inventory self-report) were randomized to a 14-day fully self-guided MEMI (96/191, 50.3%) or self-monitoring app (95/191, 49.7%) arm. They completed web-based self-reports of 6 clinical outcome measures at prerandomization, 15-day postintervention (administered the day after the intervention ended), and 1-month follow-up time points. ER and self-compassion were assessed at preintervention and 7-day midintervention time points. Multilevel modeling determined the efficacy of MEMI on ER and self-compassion domains from pretrial to midintervention time points. Bootstrapped parallel multilevel mediation analysis examined the mediating role of pretrial to midintervention ER and self-compassion domains on the efficacy of MEMI on 6 clinical outcomes.

RESULTS

Participants demonstrated strong compliance, with 78% (149/191) engaging in at least 80% of the MEMI and self-monitoring prompts. MEMI was more efficacious than the self-monitoring app in decreasing ER goal-directed behavior difficulties (between-group Cohen d=-0.24) and lack of emotional clarity (Cohen d=0.16) and increasing self-compassion social connectedness (Cohen d=0.19), nonidentification with emotions (Cohen d=0.16), and self-kindness (Cohen d=0.19) from pretrial to midintervention time points. The within-group effect sizes from pretrial to midintervention were larger in the MEMI arm than in the self-monitoring app arm (ER goal-directed behavior difficulties: Cohen d=-0.73 vs -0.29, lack of emotional clarity: Cohen d=-0.39 vs -0.21, self-compassion domains of social connectedness: Cohen d=0.45 vs 0.19, nonidentification with emotions: Cohen d=0.63 vs 0.48, and self-kindness: Cohen d=0.36 vs 0.10). Self-monitoring, but not MEMI, alleviated ER emotional awareness issues (between-group Cohen d=0.11 and within-group: Cohen d=-0.29 vs -0.13) and reduced self-compassion acknowledging shared human struggles (between-group Cohen d=0.26 and within-group: Cohen d=-0.23 vs 0.13). No ER and self-compassion domains were mediators of the effect of MEMI on SAD symptoms (P=.07-<.99), generalized anxiety symptoms (P=.16-.98), depression severity (P=.20-.94), repetitive negative thinking (P=.12-.96), and trait mindfulness (P=.18-.99) from pretrial to postintervention time points. Similar nonsignificant mediation effects emerged for all of these clinical outcomes from pretrial to 1-month follow-up time points (P=.11-.98).

CONCLUSIONS

Brief, fully self-guided, mobile MEMIs efficaciously increased specific self-compassion domains and decreased ER difficulties associated with goal pursuit and clarity of emotions from pretrial to midintervention time points. Higher-intensity MEMIs may be required to pinpoint the specific change mechanisms in ER and self-compassion domains of SAD.

Integrating mindfulness into the extended process model of emotion regulation: The dual-mode model of mindful emotion regulation

Extensive research has been conducted regarding how people manage their emotions. Within this research, there has been growing attention toward the role of mindfulness in emotion regulation. While prior reviews have discussed mindfulness in the context of emotion regulation, they have not provided a thorough integration using the prevailing models of emotion regulation or mindfulness. The present review discusses the Extended Process Model of Emotion Regulation and Monitoring and Acceptance Theory of mindfulness in order to propose a novel integrated framework, the Dual-mode Model of Mindful Emotion Regulation (D-MER). This model proposes two "modes" of mindfulness: Implementation and facilitation. Implementation posits that mindfulness skills can be used as emotion regulation strategies through attentional deployment and cognitive change. Facilitation posits that mindfulness as a state or trait affects emotion generation and regulation through effects on cognitive processes and positive or negative valence systems. Further, the D-MER posits that mindfulness experience can improve the efficiency of mindfulness-based emotion regulation strategies (implementation) while effects of mindfulness on emotion regulation processes become increasingly trait-like and automatic over time (facilitation). Empirical and theoretical support for this model are discussed, specific hypotheses to guide further research are provided, and clinical implications are presented. Use of this model may identify mechanisms underlying the interaction between mindfulness and emotion regulation which can be used in ongoing affective and clinical research.

Dynamic bidirectional relation between state mindfulness and suicidal ideation among female college students: The moderating effect of trait mindfulness

Research has indicated that mindfulness is a protective factor against suicidal ideation. However, the dynamic reciprocal relation between them has been understudied. In this study, 110 female college students with suicidal ideation completed a measure of trait mindfulness and a 28-day diary of suicidal ideation and three-dimensional state mindfulness, including acting with awareness, present-moment attention, and nonjudgmental acceptance. Dynamic structural equation modeling was used to examine the dynamic and bidirectional effects between dimensions of state mindfulness and suicidal ideation and the moderating effect of trait mindfulness. Results showed that suicidal ideation predicted lower levels of present-moment attention the next day. More importantly, there was a dynamic and bidirectional relation between nonjudgmental acceptance and suicidal ideation for people with trait mindfulness higher than the average level (i.e., M + 0.15SD). Our findings suggested that studies and interventions on suicide should pay more attention to specific dimensions of state mindfulness and trait mindfulness.

Deep rest: An integrative model of how contemplative practices combat stress and enhance the body's restorative capacity

Engaging in contemplative practice like meditation, yoga, and prayer, is beneficial for psychological and physical well-being. Recent research has identified several underlying psychological and biological pathways that explain these benefits. However, there is not yet consensus on the underlying overlapping physiological mechanisms of contemplative practice benefits. In this article, we integrate divergent scientific literatures on contemplative practice interventions, stress science, and mitochondrial biology, presenting a unified biopsychosocial model of how contemplative practices reduce stress and promote physical health. We argue that engaging in contemplative practice facilitates a restorative state termed "deep rest," largely through safety signaling, during which energetic resources are directed toward cellular optimization and away from energy-demanding stress states. Our model thus presents a framework for how contemplative practices enhance positive psychological and physiological functioning by optimizing cellular energy consumption.

Testing the monitor and acceptance theory: the role of training-induced changes in monitoring- and acceptance-related capacities after attention-based, socio-emotional, or socio-cognitive mental training in reducing cortisol stress reactivity

Mindfulness-based interventions have become a popular means to reduce stress. However, the specific mechanisms driving observed stress reduction remain understudied. The Monitor and Acceptance Theory suggests that the cultivation of monitoring and acceptance skills are necessary moderators of practice-induced stress reduction. In the context of the ReSource Project, a large healthy adult sample underwent three 3-month mental training modules targeting either attentional (Presence module), socio-affective (Affect module) or socio-cognitive skills (Perspective module). In the current study, the development of a range of inter-individual differences in mindfulness-, interoception- and compassion-related traits - which mapped to either monitoring or acceptance categories - was tracked. The relationship of these training-induced changes with cortisol stress reactivity after the three distinct 3-month training modules was explored. We found that stress sensitivity was particularly modulated by a differential adaptivity of one cultivated attentional capacity - Attention regulation - which predicted higher cortisol reactivity after mere attention training (Presence) but was associated with lower stress-induced cortisol release after additional socio-affective and socio-cognitive practice (Affect and Perspective). However, this effect did not survive multiple comparisons correction, and analyses were limited by the sample size available. We conclude that our study provides preliminary support of the Monitor and Acceptance Theory, lending weight to the advantage of primary attentional increases in order to fully harness the beneficial effects of socio-affective training, ultimately leading to stress reduction. Although training-induced increases in acceptance were not directly shown to contribute to lowering cortisol stress reactivity, the data suggest an additional benefit of socio-affective and socio-cognitive training that is not directly captured within the current analyses. Our study corroborates the importance of going beyond the training of attention monitoring to foster stress resilience, and highlights that mental training relies on the co-development of several interacting processes to successfully attenuate stress. Further exploring the overarching concept of acceptance in future research may prove beneficial to the theoretical framework of MAT, and in understanding the processes by which stress reduction occurs.

Trait Mindfulness in Psychotic Disorders: Dimensions Predicting Symptoms, Cognition, and Functional Outcome

Mindfulness-based treatments are efficacious for psychotic disorders (PD). However, which components of mindfulness (i.e., attentive monitoring and nonjudgmental acceptance) are most relevant treatment targets is unclear. Further, there is a dearth of literature examining clinical correlates of mindfulness in people with PD. The present study aimed to examine group differences and clinical correlates of mindfulness in people with PD. We hypothesized that PD would report lower monitoring and acceptance than CN and that mindfulness components would be associated with symptoms including dysfunctional beliefs, alexithymia, neurocognitive ability, positive symptoms, and mood symptoms. Groups included individuals with PD (n = 54) and nonpsychiatric controls (n = 55). Participants completed self-report measures of mindfulness and related constructs and clinical interviews of symptoms. Results of ANOVA models indicated that global mindfulness was lower in PD relative to CN, with greatest differences evident for acceptance in the affective psychosis group. Regression models found that greater monitoring was associated with improved neurocognitive performance, while acceptance was associated with lower defeatist beliefs, alexithymia, and depression/anxiety symptoms. Results highlight the importance of targeting acceptance in the psychosocial treatment of PDs, especially for those with mood symptoms.

Mindfulness and negative emotions among Chinese college students: chain mediation effect of rumination and resilience

Objective

This study examines the mediation effect of rumination and resilience between the relationship of mindfulness and negative emotions in Chinese college students.

Method

A total of 3,038 college students (19.94 ± 1.10) were investigated by Mindfulness Attention Awareness Scale (MASS), Rumination Response Style Scale (RRS), Resilience Scale (RES) and Depression-anxiety-pressure scale (DASS-21), and the mediation analyses were conducted by adopting PROCESS macro in the SPSS software.

Results

① Mindfulness was negatively associated with rumination and negative emotions (r = -0.69, -0.72; P < 0.01), and positively associated with resilience (r = 0.63, P < 0.01). Rumination was negatively associated with resilience (r = -0.59, P < 0.01), and positively associated with negative emotions (r = 0.83, P < 0.01). Resilience was negatively associated with negative emotions (r = -0.71, P < 0.01). ② Mindfulness can not only directly predict negative emotions (95%CI, -0.12~-0.09) but also affects negative emotions through three indirect paths: Rumination was a mediator (95%CI, -0.24~-0.20), resilience was a mediator (95%CI, -0.07~-0.06), and resilience and rumination were a chain mediator (95%CI, -0.04 ~ -0.03).

Conclusion

Mindfulness not only influences negative emotions directly, but also through the mediating effect of rumination and resilience indirectly.

A randomized controlled trial of mindfulness: effects on university students' mental health

BACKGROUND

The development of mental health disorders is common in the university population, and mindfulness-based interventions (MBIs) seem to be effective in addressing them in different contexts. Thus, this study investigated the impact of an 8-week MBI adapted to university students from the Mindfulness-Based Relapse Prevention (MBSR) on different symptoms related to mental health problems, specifically symptoms of anxiety, depression, stress and insomnia.

METHODS

University students (n = 136) were randomized into MBI group (n = 71) or wait-list group (n = 65). All participants completed self-administered questionnaires before and after the intervention, and the experimental group answered questionnaires weekly during intervention. Generalized mixed models were used to assess the effects of the intervention.

RESULTS

There were improvements in the symptoms of stress (B = 5.76, p < 0.001), depression (B = 1.55, p < 0.01) and insomnia (B = 1.35, p = 0.020) from the beginning of the intervention to the final assessment when it was compared to the control group. No effect was found in respect of trait anxiety. The MBI was found to be effective in reducing important symptoms related to university students' mental health, possibly grounding further research on the intervention's potential of preventing the development of mental disorders.

TRIAL REGISTRATION

The research was registered in the Brazilian Registry of Clinical Trials (ReBEC) - number RBR-63qsqx, approved at 09/16/2019.

Age-related reductions in arousal-enhanced memory are moderated by trait emotion regulation

Emotional arousal is known to enhance episodic memory in young adults. However, compared to valence, little is known about how healthy aging impacts arousal-enhanced memory effects. Furthermore, while emotion regulation is believed to improve with age, it is unclear how individual differences in emotion regulation influence arousal-enhanced memory. In this large-scale online study, we investigated the impact of age and individual differences in emotion regulation on arousal-enhanced memory. During encoding, participants made arousal ratings about negative, neutral, and positive images, and we compared their subsequent memory of high and low-arousal images. We found the impact of emotional arousal on memory was reduced with age, especially for older adults who habitually suppress their emotions. Our findings show that arousal-related memory benefits are reduced with advancing age, and that individual differences in habitual usage of emotion regulation impact these age-related alterations.

Return to valued activities: Survivors' experiences of adaptation and growth after treatment for head and neck cancer

OBJECTIVE

The objective of this study was to explore the experiences of head and neck cancer (HNC) survivors who returned to valued activities to understand how they reconstruct their lives following HNC diagnosis and treatment.

METHODS

A qualitative research approach based on social constructionist theory was used. A total of 21 in-depth semi-structured interviews were conducted with adults diagnosed with any type of HNC in the previous 6 years. Reflexive thematic analysis was used to identify themes.

RESULTS

HNC presents a unique trauma following which some survivors navigate paths back to meaningful activities. The experiences of HNC survivors who adapted to life after treatment described internal and external change and development, identified by three themes; Mindfulness; Gratitude; and Adaptation.

CONCLUSION

People diagnosed with HNC frequently experience lasting effects and other survivorship issues, however some survivors were able to return to valued activities and recreate a meaningful lifestyle reflecting the possibility of post traumatic growth. This study provides insight into the experiences of head and neck cancer survivors who were able to make meaning and find internal and external growth following treatment. These findings can be used to inform advanced communication skills training for oncology health professionals and psychoeducational courses for people diagnosed with head and neck cancer in the future.

Embodied Mindfulness Questionnaire: Scale Development and Validation

Recently developed mindfulness scales have integrated aspects of the body in measuring mindfulness unlike other established scales. However, these scales focused solely on body awareness and did not embrace all aspects of mindfulness and the body. Specifically, they did not integrate embodiment in mindfulness. The proposed Embodied Mindfulness Questionnaire (EMQ) aims to operationalize the proposed notion of "embodied mindfulness" by grounding it into five dimensions, each representing a set of skills that can be cultivated through training and practice: (a) Detachment from Automatic Thinking, (b) Attention and Awareness of Feelings and Bodily Sensations, (c) Connection with the Body, (d) Awareness of the Mind-Body Connection, and (e) Acceptance of Feelings and Bodily Sensations. The EMQ items were developed through consultations with a panel of eight graduate students and a group of 10 experts in the field. Results from a series of three studies supported the proposed five subscales of EMQ and suggested that these subscales are independent and supported by convergent and discriminant evidence. In addition, results suggested that scores of EMQ subscales are different in terms of sensitivity to mindfulness training or meditation practice and experience. Limitations, as well as theoretical and practical implications of the EMQ subscales, are thoroughly discussed.

Self-judgment dissected: A computational modeling analysis of self-referential processing and its relationship to trait mindfulness facets and depression symptoms

Cognitive theories of depression, and mindfulness theories of well-being, converge on the notion that self-judgment plays a critical role in mental health. However, these theories have rarely been tested via tasks and computational modeling analyses that can disentangle the information processes operative in self-judgments. We applied a drift-diffusion computational model to the self-referential encoding task (SRET) collected before and after an 8-week mindfulness intervention (n = 96). A drift-rate regression parameter representing positive-relative to negative-self-referential judgment strength positively related to mindful awareness and inversely related to depression, both at baseline and over time; however, this parameter did not significantly relate to the interaction between mindful awareness and nonjudgmentalness. At the level of individual depression symptoms, at baseline, a spectrum of symptoms (inversely) correlated with the drift-rate regression parameter, suggesting that many distinct depression symptoms relate to valenced self-judgment between subjects. By contrast, over the intervention, changes in only a smaller subset of anhedonia-related depression symptoms showed substantial relationships with this parameter. Both behavioral and model-derived measures showed modest split-half and test-retest correlations. Results support cognitive theories that implicate self-judgment in depression and mindfulness theories, which imply that mindful awareness should lead to more positive self-views.

Self-reported physical function is strongly related to pain behavior and pain interference and weakly related to physical capacity in people with chronic low back pain

BACKGROUND

Inclusion of self-reported and capacity-based measures may help to further elucidate the interactive link between how people think and move.

OBJECTIVE

To characterize the relationship between self-reported factors of physical function and pain with objective physical capacity measures.

DESIGN

Cross-sectional study of 328 adults with chronic low back pain (CLBP).

METHOD

Spearman correlations assessed the relationship between pairs of measures. Multiple linear regression models assessed the association between self-reported measures of physical function and the grouping of physical capacity measures. Self-reported measures included Roland Morris Disability Questionnaire (RMDQ), PROMIS Physical Function, Pain Behavior, and Pain Interference; Fear-Avoidance Beliefs Questionnaire (FABQ), Pain Catastrophizing Scale (PCS), and Chronic Pain Acceptance Questionnaire (CPAQ). Capacity measures included walking speed and endurance, lower extremity functional strength, lumbopelvic range of motion, and trunk endurance.

RESULTS

PROMIS Physical Function was directly and weakly correlated with walking speed (ρ = 0.26, 2-min walk) and inversely and weakly correlated with lower extremity strength (ρ = -0.29, 5x sit-to-stand). RMDQ was not correlated with any of the capacity-based measures. PROMIS Physical Function was inversely and moderately correlated with Pain Interference (ρ = -0.48) and Pain Behavior (ρ = -0.43), PCS (ρ = -0.36), and FABQ (ρ = -0.31). The RMDQ was strongly correlated with PROMIS Physical Function (ρ = -0.56), Pain Behavior (ρ = 0.51) and Pain Interference (ρ = 0.49); and moderately correlated with PCS (ρ = 0.37) and FABQ (ρ = 0.33). PROMIS Physical Function and RMDQ were not correlated with CPAQ. Lower scores on PROMIS Physical Function were weakly associated with lower measures of lower extremity strength (-0.30, 95% CI: -0.51 to -0.09, p = 0.005). Higher scores on RMDQ were also weakly associated with lower measures of lower extremity strength (0.26, 95% CI: 0.11 to 0.41, p = 0.001).

CONCLUSIONS

A strong association emerged between self-reported limitations in physical function, pain behavior, and pain interference. A weak association emerged between self-reported physical function and lower extremity strength.

Effectiveness Evaluation of Repetitive Transcranial Magnetic Stimulation Therapy Combined with Mindfulness-Based Stress Reduction for People with Post-Stroke Depression: A Randomized Controlled Trial

Background: Post-stroke depression (PSD) is most prevalent during the rehabilitative period following a stroke. Recent studies verified the effects of repetitive transcranial magnetic stimulation therapy (rTMS) and mindfulness-based stress reduction (MBSR) in patients with depression. However, the effectiveness and prospect of application in PSD patients remain unclear. This study sought to evaluate the effectiveness of a combined intervention based on rTMS and MBSR for the physical and mental state of PSD patients. Methods: A randomized, double-blind, sham-controlled study design was employed. Participants were recruited from the Rehabilitation Medicine Centre and randomly assigned to receive either MBSR combined with active or sham rTMS or sham rTMS combined with general psychological care. We used a 17-item Hamilton Depression Rating Scale (HAMD-17), a mini-mental state examination (MMSE), the Modified Barthel Index (MBI), and the Pittsburgh Sleep Quality Index (PSQI) to evaluate depressed symptoms, cognitive function, activities of daily living (ADL), and sleep quality at baseline, post-intervention, and the 8-week follow-up. A two-factor analysis of variance was used to compare differences between groups, and Pearson’s linear correlation was used to analyze the possible relationship between variables and potential predictors of depression improvement. Results: Seventy-two participants were randomized to rTMS−MBSR (n = 24), sham rTMS−MBSR (n = 24), or sham rTMS−general psychological care (n = 24). A total of 71 patients completed the questionnaire, a 99% response rate. There were significant time and group interaction effects in HAMD-17, MMSE, MBI, and PSQI scores (p < 0.001). The repeated-measure ANOVA showed a significant improvement of all variables in rTMS−MBSR compared to sham rTMS−MBSR and sham rTMS combined with general psychological care (p < 0.05). Additional results demonstrated that cognitive function, sleep quality, and activities of daily living are associated with depressive symptoms, and cognitive function is a potential variable for improved depression. Conclusion: Depressive symptoms can be identified early by assessing cognitive function, and rTMS−MBSR might be considered a potentially helpful treatment for PSD.

Mindfulness to Manage Moral Injury: Rationale and development of a live online 7-week group intervention for veterans with moral injury

Background

Military service puts service members at risk for moral injury. Moral injury is an array of symptoms (e.g., guilt, shame, anger) that develop from events that violate or transgress one's moral code.

Objective

We describe adaption of in-person mindfulness training program, Mindfulness to Manage Chronic Pain (MMCP), to address symptoms of moral injury to be delivered live via the web. We discuss how we will assess benchmarks (i.e., recruitment, credibility and acceptability, completion rates, and adherence) of the Mindfulness to Manage Moral Injury (MMMI) program.

Methods

Aim 1: To develop and then adapt the MMCP program based on feedback from experts and veterans who took part in Study 1. Aim 2: To develop an equally intensive facilitator-led online Educational Support (ES) program to serve as a comparison intervention and conduct a run-through of each program with 20 veterans (10 MMMI; 10 ES). Aim 3: To conduct a small-scale randomized controlled trial (N = 42 veterans; 21 MMMI; 21 ES) in which we will collect pre-post-test and weekly benchmark data for both refined intervention arms.

Results

Study 1 and 2 are completed. Data collection for Study 3 will be completed in 2022.

Conclusion

MMMI is designed to provide a live facilitated mindfulness program to address symptoms of moral injury. If Study 3 demonstrates good benchmarks, with additional large-scale testing, MMMI may be a promising treatment that can reach veterans who may not seek traditional VAMC care and/or who prefer a web-based program.

Trait Acceptance Buffers Aggressive Tendency by the Regulation of Anger during Social Exclusion

Social exclusion has led to increased negative emotions and aggressive behaviors, two outcomes that are correlated with each other. Thus, the down-regulation of negative emotions appears to play a crucial role in reducing the tendency for aggressive behavior. However, this assumption has not yet been tested. To this end, a total of 397 undergraduates reported their aggressive tendencies, state emotions and trait acceptance by completing corresponding questionnaires, and a recall paradigm was used to induce experiences of social exclusion. The results showed that in the context of social exclusion, (1) trait acceptance was negatively correlated with negative emotions and aggressive tendency but was positively correlated with positive emotions; (2) negative emotions, rather than positive emotions, were positively correlated with aggressive tendency; (3) increased trait acceptance buffered the experience of anger, which is, in turn, related to reduced aggressive tendency; (4) trait acceptance also downregulated the feeling of sadness, which is, however, related to increased aggression; (5) the mediator of sadness was smaller in effect size than that of anger. Taken together, these results suggest that negative emotions are associated with aggression in the context of social exclusion, and the habitual use of an acceptance strategy was conductive to decreasing aggressive tendencies by decreasing anger.

App-based mindfulness meditation reduces perceived stress and improves self-regulation in working university students: A randomised controlled trial

We investigated whether a brief mindfulness meditation programme delivered via a smartphone app improves perceived stress, self-regulation and life satisfaction in part-time working university students. Mindfulness and cognitive reappraisal were analysed as potential mediators. A total of 64 university students working at least 20 h per week during the semester were randomised to either a mindfulness-based mobile intervention or a wait-list control condition. Participants in the intervention group were asked to complete one training session of 10-15 min per day using the app. Psychological measures were assessed via a self-report questionnaire at baseline and after 8 weeks. The online mindfulness programme was found to significantly decrease perceived stress (η_p ²  = .180, a large effect). It also increased self-regulation (η_p ²  = .195, a large effect), mindfulness (η_p ²  = .174; a large effect) and cognitive reappraisal (η_p ²  = .136, a medium effect). Increments in life satisfaction were not significant. Changes in self-regulation were mediated by increased mindfulness. Overall, the mobile application was effective in improving mental well-being and coping abilities in a non-clinical sample, encouraging further development of digital health treatments.

Sexual Minority Status, Affect Lability, and Suicide Ideation: Buffering Role of Trait Mindfulness

OBJECTIVE

Emotion regulation has been proposed as a mechanism driving sexual orientation disparities in suicide ideation (SI), but little research has examined the role of affect lability in the association of sexual minority identity and SI. As prior research has found trait mindfulness to be associated with lower SI, the objective of the present study was to examine the buffering role of mindfulness in the associations of sexual orientation, affect lability, and SI.

METHOD

The present study used a moderated mediation model to examine a cross-sectional dataset consisting of heterosexual (n = 1511) and sexual minority (n = 355) U.S. college students (N = 1866), to examine whether five facets of mindfulness moderated the indirect association of sexual minority identity on SI via affect lability.

RESULTS

As predicted, sexual minority identity was associated with higher affect lability, which in turn was associated with higher SI. Acting with awareness (i.e., attending to the present activities), describing (i.e., the ability to verbalize inner experiences), and non-judging (i.e., refraining from judging inner experiences) buffered the indirect association of sexual minority identity on SI via affect lability, such that the indirect association weakened at higher levels of those mindfulness facets.

CONCLUSIONS

Our results provide a better understanding of the emotion regulation mechanisms underlying the higher risk of SI among sexual minorities. Future research is needed to examine mindfulness facets as buffers against SI among other communities, and to examine the efficacy of emotion regulation and mindfulness interventions in reducing suicide ideation and other aspects of suicidality (i.e., plans/attempts).HighlightsSexual orientation disparities in suicide ideation (SI) and affect lability.Sexual minority identity linked to higher SI via higher affect lability.Three mindfulness facets attenuated indirect association of identity on SI.

The impact of a brief mindfulness training on interoception: A randomized controlled trial

Interoception is a collection of different representations of signals originating within the body. The way of perceiving these signals seems to be related to both emotion regulation and dysregulation, and its dysfunction is implicated across a variety of affective disorders. There is a growing body of research investigating the relationship between mindfulness meditation practices and interoception showing an increase in interoceptive processes with regular training. In this study, we assessed the effects of a three-day mindfulness training on interoceptive accuracy and sensibility in a young healthy adult sample. Moreover, we also performed a mediation analysis on interoceptive sensibility and anxiety. Healthy participants (n = 40) naive to mindfulness practices were randomized to a brief mindfulness training (MT) (n = 20, females = 10) or to an active control group (n = 20, females = 10). Participants were assessed before and after the 3-days intervention for both groups on measures of interoception and anxiety in a modified intention-to-treat approach. The brief mindfulness training group increased interoceptive sensibility while active control had no effects on this variable. Five out of eight subdomains of interoceptive sensibility were significantly improved after mindfulness training. There was no significant difference in interoceptive accuracy after training. The effect of a brief mindfulness training on interoceptive sensibility mediated changes in the anxiety state. To date, this is the first study showing a plausible mechanism of a brief mindfulness training to explain the anxiolytic effects of meditation practices.

Attachment insecurity moderates emotion responses to mindfulness and loving-kindness meditation in adults raised in low socioeconomic status households

Research on attachment theory holds that insecure attachment influences people's daily social and emotional experiences. Mindfulness meditation and loving-kindness meditation have been associated with improvements in physical and mental well-being often through their influence on emotion experience and regulation. Yet, little research has examined how emotional well-being may be improved in insecurely attached individuals through meditation practice. We suspected that the emotion profiles of anxious and avoidant attachment may shift with meditation training, both across time and on a particular day. Improving emotional well-being may be especially consequential for those most at risk for negative health outcomes in late life. A diverse community sample of midlife adults raised in low-SES homes (N = 113; 55% white, 87.5% female) completed daily emotion reports for 10 weeks, during which they received 6 weeks of meditation training, randomized to either loving-kindness or mindfulness meditation practice. Results from growth curve analyses revealed that individuals with greater attachment anxiety and randomized to mindfulness meditation reported significant increases over time in positive emotions alongside decreases in negative emotions. Those high in attachment avoidance reported significant decreases in negative emotions in both meditation groups. On the daily level, within-person dose-response analyses revealed that individuals with greater attachment anxiety showed the most consistent dose-response relations between the duration of either meditation practice and same-day increases in positive emotions and decreases in negative emotions. These findings highlight how meditation interventions can shift emotion profiles of insecurely attached midlife adults who are at heightened risk for late life chronic illnesses.

Take my advice: Physiological measures reveal that intrinsic emotion regulation is more effective under external guidance

Research into emotion regulation (ER) has focused primarily on the intra-personal process through which we regulate our own emotions intrinsically. More recently, however, studies have begun to explore the inter-personal nature of intrinsic ER - that is, how we regulate our emotions under the guidance of others. Preliminary evidence suggests that ER might be more effective when implemented in an inter- compared with an intra-personal manner, but these findings are based almost exclusively on self-reported ratings that capture only the subjective experience of emotions. The current study therefore investigated whether this apparent superiority of inter-personal intrinsic ER could be replicated and extended to physiological measures of affective reactions - namely, various metrics of electrodermal activity. In a within-subjects design, a sufficiently powered sample (N = 146) were required to down-regulate their emotional reactions to negatively valenced images using an ER strategy they had chosen themselves intra-personally or one that had been recommended to them inter-personally. Physiological responses converged to demonstrate the greater effectiveness of inter- over intra-personal ER in decreasing negative affective reactions, despite subjective ratings suggesting that participants perceived the opposite to be true. The superiority of inter- over intra-personal ER in physiological recordings was unrelated to individuals' perceptions of their ability to regulate their own emotions, however, and so it remains to be seen if and how such benefits extend to clinical populations.

Are sick people really more impulsive?: Investigating inflammation-driven impulsivity

In both animals and humans, inflammatory stimuli - especially infections and endotoxin injections - cause "sickness behaviors," including lethargy, malaise, and low mood. An emerging line of research asserts that inflammation may provoke present-focused decision making and impulsivity. The current article assesses that claim in the context of the broader literature - including preclinical models and clinical interventions. This literature presents three challenges to purported inflammation-impulsivity link that have not been addressed to date: (1) the nebulous and imprecise definition of impulsivity; (2) reverse causality; and (3) a lack of causal evidence. These challenges point to ways in which future research designs can improve upon the extant literature to further explore the ostensible relationship between inflammation and impulsivity.

Mindfulness on Daily Life Coping in People Experiencing Psychosis: A Randomized Controlled Trial

Background/Objective

Cognitive Behavior Therapy for psychosis (CBTp) is a recommended treatment for psychoses whose effect is mediated by coping. Mindfulness (MBI) have shown positive effects in psychosis. This study examines the hypothesis that combining CBTp+MBI could improve coping with day-to-day life in psychosis better than CBTp alone in people attending a public community rehabilitation center.

Method

Fifty-six outpatients were recruited and randomly allocated either to CBTp or CBTp+MBI. Measures comprised PANSS interview and COPE Inventory. Data were analyzed using a repeated measures ANOVA and RCI calculation.

Results

There were no statistical differences between groups at pre-treatment. Significant statistical differences were found for the interaction Treatment x Time in Mental disengagement (F = 5.65, p = .021, η2 = .102), Acceptance (F = 7.69, p = .008, η2 = .133), and Suppressing competing activities (F = 4.62, p = .037, η2 = .085).

Conclusions

MBI promotes specific coping styles in people who experience psychosis that otherwise are not improved with CBTp. Only the MBI group improved acceptance of the presence of the stressor and reduced mental disengagement from the context. The intervention is feasible and effective for public healthcare settings.

Clarifying the Relationship Between Self-Compassion and Mindfulness: an Ecological Momentary Assessment Study

Objectives

Self-compassion entails relating to one's negative experiences with awareness, acceptance, and kindness, and it is associated with greater well-being. The Self-Compassion Scale (SCS) includes mindfulness, which is theorized as a necessary precursor to a self-compassionate response. The present study examined associations of the SCS and its subscales with mindfulness and decentering at baseline and in daily life to clarify the measure's construct validity. We also tested whether self-compassion moderates the association between mindfulness and eudaimonic well-being in daily life during occasions of increased negative affect.

Method

The sample of 172 community adults completed the SCS at baseline and a 7-day ecological momentary assessment. The SCS's construct validity was tested with multilevel correlations and regressions. We tested the interaction of momentary mindfulness, momentary negative affect, and dispositional self-compassion in predicting momentary well-being.

Results

Results generally supported the construct validity of the SCS, but SCS mindfulness subscales were most closely associated with decentering scales in daily life. Higher dispositional self-compassion, higher momentary mindful awareness, and lower momentary negative affect predicted higher momentary eudaimonic well-being. However, self-compassion did not interact with momentary mindful awareness and negative affect.

Conclusions

The SCS generally related to measures of mindfulness and decentering as expected, but further work should be done to clarify subscale construct validity. Self-compassion was predictive of higher momentary eudaimonic well-being in people's daily lives, supportive of ecological validity, but trait levels of self-compassion did not affect the relationship between momentary mindfulness and eudaimonic well-being.

Profiles of mindfulness in cancer patients and associations with psychological outcomes and coping strategies: A person-centered approach

OBJECTIVE

Previous research confirmed the benefits of mindfulness for cancer patients' psychological well-being, but few studies considered the value of possible distinct combinations of mindfulness skills. This study aimed to (1) identify distinct mindfulness profiles in cancer patients, (2) examine socio-demographic predictors of patients with distinct profiles, and (3) examine associations of mindfulness profiles with psychological outcomes and coping strategies.

METHODS

This cross-sectional study included 245 people with heterogeneous types of cancer. Latent profile analysis was applied to identify distinct profiles of mindfulness. The Bolck-Croon-Hagenaars method was used to examine how mindfulness profiles related to socio-demographic characteristics, psychological outcomes, and coping strategies.

RESULTS

Four mindfulness profiles were identified: "average mindfulness" (50%), "judgmentally observing" (20%), "high mindfulness" (15%), and "non-judgmentally aware" (15%). Patients with "high mindfulness" profile tended to have higher educational attainment, and reported better psychological outcomes (i.e., low on depression and negative affect and high on positive affect) as well as better coping strategies (i.e., high positive reappraisal and low rumination).

CONCLUSION

This study confirms the existence of distinct mindfulness profiles in cancer patients and suggest that patients high in mindfulness are the most adaptive.
