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

ABSTRACT 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.

The Effectiveness of a Neurofeedback-Assisted Mindfulness Training Program Using a Mobile App on Stress Reduction in Employees: Randomized Controlled Trial.

Mindfulness-based training programs have consistently shown efficacy in stress reduction. However, questions regarding the optimal duration and most effective delivery methods remain. This research explores a 4-week neurofeedback-assisted mindfulness training for employees via a mobile app. The study's core query is whether incorporating neurofeedback can amplify the benefits on stress reduction and related metrics compared with conventional mindfulness training. A total of 92 full-time employees were randomized into 3 groups: group 1 received mobile mindfulness training with neurofeedback assistance (n=29, mean age 39.72 years); group 2 received mobile mindfulness training without neurofeedback (n=32, mean age 37.66 years); and group 3 were given self-learning paper materials on stress management during their first visit (n=31, mean age 38.65 years). The primary outcomes were perceived stress and resilience scales. The secondary outcomes were mindfulness awareness, emotional labor, occupational stress, insomnia, and depression. Heart rate variability and electroencephalography were measured for physiological outcomes. These measurements were collected at 3 different times, namely, at baseline, immediately after training, and at a 4-week follow-up. The generalized estimating equation model was used for data analysis. The 4-week program showed significant stress reduction (Wald χ22=107.167, P<.001) and improvements in psychological indices including resilience, emotional labor, insomnia, and depression. A significant interaction was observed in resilience (time × group, Wald χ42=10.846, P=.02). The post hoc analysis showed a statistically significant difference between groups 1 (least squares mean [LSM] 21.62, SE 0.55) and 3 (LSM 19.90, SE 0.61) at the posttraining assessment (P=.008). Group 1 showed a significant improvement (P<.001) at the posttraining assessment, with continued improvements through the 1-month follow-up assessment period (LSM 21.55, SE 0.61). Physiological indices were analyzed only for data of 67 participants (22 in group 1, 22 in group 2, and 23 in group 3) due to the data quality. The relaxation index (ratio of alpha to high beta power) from the right electroencephalography channel showed a significant interaction (time × group, Wald χ22=6.947, P=.03), with group 1 revealing the highest improvement (LSM 0.43, SE 0.15) compared with groups 2 (LSM -0.11, SE 0.10) and 3 (LSM 0.12, SE 0.10) at the 1-month follow-up assessment. The study demonstrated that the neurofeedback-assisted group achieved superior outcomes in resilience and relaxation during the 4-week mobile mindfulness program. Further research with larger samples and long-term follow-up is warranted. ClinicalTrials.gov NCT03787407; https://clinicaltrials.gov/ct2/show/NCT03787407.

Effects of mindfulness training on decision-making in critical and high-demand situations: A pilot study in combat aviation

The current study investigated the effects of a mindfulness-based training program (Attentional Regulation Optimization) on decision-making in an elite population operating in a highly-demanding context, namely the actions of fighter pilots in critical flight situations that lead to ejection. Our hypothesis was that both mindfulness skills and decision-making performance would improve in pilots who participated in the ARO program (n = 7), compared to a control group (n = 8). Mindfulness skills were measured with the FFMQ-15. Decision-making performance was evaluated in two tests that were implemented in scenarios in a full flight simulator. Five dependent variables were assessed, corresponding to the phases of the decision-making process when faced with an in-flight failure: reaction time after the first failure input, correctness of the first action, emergency procedure score, ejection procedure score, and quality of ejection. Adherence to the ARO program was assessed with the number of out-of-class individual mindfulness sessions and the number of out-of-class body-mind scans.No statistically significant improvement in mindfulness skills for the ARO group compared to the control group were found. Reaction time was significantly shortened for the ARO group compared to the control group—but only for complex failures. A positive effect on the correctness of the first action was also found. On the other hand, ARO training had no significant effect on the downstream phases of decision-making (emergency procedure score, ejection procedure score and quality of ejection).Given the small sample size, these results must be considered with caution. However, they open up interesting avenues for future work, notably with regard to the benefits of mindfulness training on perceptual and attentional skills (to detect flight failure cues) and cognitive control skills (to diagnose and select appropriate procedures). From an operational perspective, the program appears to have beneficial effects on safety and performance in elite populations who must face critical situations.

Cultivating well-being in engineering graduate students through mindfulness training.

The mental health crisis in graduate education combined with low treatment rates among engineering graduate students underscores the need for engineering graduate programs to provide effective methods to promote well-being. There is an extensive body of neuroscience research showing that contemplative practices, such as mindfulness, produce measurable effects on brain function and overall well-being. We hypothesized that a mindfulness-based training program designed for engineering graduate students would improve emotional well-being and, secondarily, enhance research capacity. An initial pilot study was conducted at a single institution (Phase 1), followed by a larger study conducted at both the original and a second institution (Phase 2) to gather additional data and show the program's transferability. The program comprised eight weekly mindfulness training sessions. Individuals in the study were randomly assigned to either an intervention group or wait-list control group. We administered pre- and post-test surveys with quantitative measures designed to assess emotional and physical well-being, as well as creativity, research satisfaction, and desire to contribute to the betterment of society. Participants also completed a summative survey to evaluate the impact of the program on their well-being and research. Analysis revealed statistically significant findings: improved emotional health, decreased neuroticism, increased positive affect, decreased negative affect, and increased mindfulness in the intervention groups compared to the control groups. Intervention groups in Phase 2 also reported statistically significant improvement in satisfaction with their research. Our findings suggest that mindfulness training has the potential to play a vital professional and personal development role in graduate engineering education.

The relationship between perceived stress and emotional intelligence in Moroccan nursing students.

Nursing students are subjected to many stressors during their clinical practicums. Emotional intelligence (EI) could act as a real stress regulator. In this perspective, we sought to study the relationship between stress and EI in a sample of Moroccan nursing students. This study was conducted using the descriptive correlational method. The statistical population consisted of the nursing students of the Higher Institute of Nursing Professions and Health Techniques of Tetouan in Morocco during the academic year 2021-2022. Among them, 146 participants were selected on the basis of simple random sampling. Participants completed a self-administered questionnaire addressing sociodemographic factors, perceived stress (the Perceived Stress in Clinical Practice Scale), and emotional intelligence (Wong and Law Emotional Intelligence Scale test). Descriptive statistics were used and Pearson's correlation coefficient was applied to assess the correlation between stress and EI, and to compare them according to socio-demographic characteristics. A linear regression analysis was calculated to analyze the effect of independent variables on perceived stress and EI. For the analysis, a level of 0.05 was chosen. The overall mean age of the students was 20.02 ± 1.12 years. Participants had moderate levels of perceived stress (M = 2.42 ± 0.77) and high levels of EI (M = 3.79 ± 1.09). A significant positive correlation between perceived stress and EI was found (r = 0.741, P < 0,05). The regression model shows that EI, education level, and clinical practice setting can explain changes in perceived stress levels and are effective and significant factors (P < 0,001). EI has been shown to be a protective factor against stress in nursing students. Those with well-developed EI have lower levels of stress. Therefore, it is suggested that a mindfulness-based training program be incorporated into the nursing curriculum to develop emotional skills and combat stress in students.

Exploring the impact of mindfulness-based training on the well-being of physical therapists.

Experimental evidence is needed to evaluate interventions that curtail burnout for physical therapists. The goal of this research was to assess the impact of mindfulness-based training (MBT) on the well-being of physical therapists. We hypothesized physical therapists would demonstrate greater work engagement, empathy, and job satisfaction, and lower depression, anxiety, stress, and moral distress following MBT. Thirteen physical therapists (10 female/3 male; 35.38 ± 9.32 years old) completed this two-arm embedded mixed-methods pilot study. The control group (n = 4) was followed while the intervention group (n = 9) completed six MBT sessions over 3 months. Sessions were assigned a representative topic area (meaning in physical therapy, situational- and self-awareness, compassion fatigue/burnout, implicit biases, establishing boundaries and managing conflict, self-care) with relevant reflective writing, small group discussions, and mindfulness strategies. Non-parametric statistics compared quantitative outcomes across and within groups, and a thematic framework matrix was established by way of qualitative description for data analysis. Physical therapists in the intervention group had improved pre- to post-scores for work engagement, mental health, and moral distress (p ≤ 0.043). Inability to effect change contributed to compassion fatigue/burnout, whereas difficulty prioritizing self/limited personal time impeded self-care. "I realized how easy it is to get caught up in life and in helping out those around you, you completely forget to take time to check in with how you are doing (Physical Therapist 3)." Implementing an MBT program demonstrates promise and may benefit the well-being of physical therapists while simultaneously enhancing employee retention and improving patient care.

An experimental approach to training interoceptive sensitivity: study protocol for a pilot randomized controlled trial

BackgroundEating in absence of hunger is quite common and often associated with an increased energy intake co-existent with a poorer food choice. Intuitive eating (IE), i.e., eating in accordance with internal hunger and satiety cues, may protect from overeating. IE, however, requires accurate perception and processing of one’s own bodily signals, also referred to as interoceptive sensitivity. Training interoceptive sensitivity might therefore be an effective method to promote IE and prevent overeating. As most studies on eating behavior are conducted in younger adults and close social relationships influence health-related behavior, this study focuses on middle-aged and older couples.MethodsThe present pilot randomized intervention study aims at investigating the feasibility and effectiveness of a 21-day mindfulness-based training program designed to increase interoceptive sensitivity. A total of N = 60 couples participating in the NutriAct Family Study, aged 50–80 years, will be recruited. This randomized-controlled intervention study comprises three measurement points (pre-intervention, post-intervention, 4-week follow-up) and a 21-day training that consists of daily mindfulness-based guided audio exercises (e.g., body scan). A three-arm intervention study design is applied to compare two intervention groups (training together as a couple vs. training alone) with a control group (no training). Each measurement point includes the assessment of self-reported and objective indicators of interoceptive sensitivity (primary outcome), self-reported indicators of intuitive and maladaptive eating (secondary outcomes), and additional variables. A training evaluation applying focus group discussions will be conducted to assess participants’ overall acceptance of the training and its feasibility.DiscussionBy investigating the feasibility and effectiveness of a mindfulness-based training program to increase interoceptive sensitivity, the present study will contribute to a deeper understanding of how to promote healthy eating in older age.Trial registrationGerman Clinical Trials Register (DRKS), no.

Psychometric Properties of the Mindfulness Inventory for Sport (German Version).

Mindfulness-based training programs are highly established in competitive and recreational sports. One of the best-known approaches is the Mindfulness-Acceptance-Commitment Approach (MAC) by Gardner and Moore), which integrates mindfulness aspects of awareness, non-judgmental attitude, and focus. Based on these aspects, Thienot and colleagues developed and validated an English language sport-specific questionnaire, the so-called Mindfulness Inventory for Sport (MIS), for the assessment of mindfulness skills in athletes. The aim of this study is to psychometrically test a German language version of the MIS (MIS-D). To assess the psychometric properties, the MIS-D was examined in an online survey with an integrated test–retest design (n = 228) for reliability (internal consistency; test–retest reliability), validity (factorial; convergent), and measurement invariance (gender; competition type). The present results support the psychometric quality of the German language version of the MIS. Necessary replications should among others focus on checking the measurement invariance for further relevant subgroups.

Mindfulness-based practices, psychological capital, burnout and performance anxiety

PurposeThe study examined the role of classroom-based mindfulness-based interventions (MBI) on psychological capital, burnout, and performance anxiety among business executives.Design/Methodology/Approach52 mid-level and senior leaders filled up a structured questionnaire on mindfulness, psychological capital, and performance anxiety before and after the intervention. They also participated in 2 week-long classroom-based mindfulness intervention programs for 1 hour daily.FindingsThe finding suggests that mindfulness-based intervention significantly improved PsyCap and reduced burnout and performance anxiety among the executives.Research limitations/implicationsSelf-report measures, sample size, and programmed duration could be a limitation. We can plan long-term (4 weeks) intervention on cross-section data for better outcomes and generalizations.Research implicationsMindfulness-based interventions can help save healthcare costs by reducing anxiety and burnout. Leaders can also quantify the value of such intervention for developing PsyCap.Practical implicationsManagement should conduct mindfulness-based training programs, and leaders can practice it in their daily routine to improve psychological resources to reduce stress and better face workplace challenges.Originality/valueThe study's contribution was using the classroom-based mindfulness-based intervention to improve psychological capital and reduce dysfunctional outcomes in leaders.

The Effectiveness of a Brief Mindfulness-Based Program for Social Work Students in Two Separate Modules: Traditional and Online

ABSTRACT Purpose This study aimed to design a brief mindfulness-based training program for social work students and examine its effectiveness and working mechanisms. Method The study used a quantitative approach to examine the program’s effectiveness for 101 undergraduate social work students in two separate modules (traditional classroom-based and online). Results One-way analysis of covariance revealed statistically significant reductions in depression, anxiety, stress, and rumination, and improvements in self-compassion and mindfulness among the intervention groups compared to the waitlist control groups. Mediation analyses showed that mindfulness, rumination, and self-compassion were mediators of the intervention effects. Discussion The brief mindfulness program can be used as an effective and introductory mindfulness program for undergraduate social work students in either classroom-based or online modules. Alternations in mindfulness, rumination, and self-compassion can be considered as possible working mechanisms.

Mindfulness, perceived partner responsiveness, and relationship quality: A dyadic longitudinal mediation model

General and domain-specific (e.g., relationship-specific) mindfulness frequently predict salutary relationship outcomes. The present preregistered study examined whether general and relationship mindfulness predicted longitudinal change in positive and negative relationship quality via greater perceived partner responsiveness (PPR). One hundred couples completed a baseline lab session (Phase 1), a 14-day diary period (Phase 2), and a 2-month follow-up survey (Phase 3). Actor-Partner Interdependence Mediation Model analyses revealed that actors’ Phase 1 relationship mindfulness—but not general mindfulness—predicted increases in their own positive relationship quality from Phase 1–3 and decreases in their own negative relationship quality from Phase 1–3 indirectly via their own Phase 2 PPR. An exploratory alternate model testing if Phase 1 PPR predicted changes in Phase 1–3 relationship quality via Phase 2 relationship mindfulness did not reveal significant indirect effects. All results held when controlling for gender, age, and relationship length, and no partner effects emerged in any analysis. These findings further elucidate the relationship-enhancing role of mindfulness in couples and highlight PPR as a critical mediator explaining the link between domain-specific mindfulness and relationship quality. Implications for mindfulness-based training programs for couples are discussed.

Mindfulness-based mobile app reduces anxiety and increases self-compassion in healthcare students: A randomised controlled trial

Objective To compare the effect of a mindfulness-based mobile application versus an in-person mindfulness-based training program in terms of reducing anxiety and increasing empathy, self-compassion, and mindfulness in a population of healthcare students. Methods The authors conducted a single-blind, randomised controlled trial with three parallel groups. Participants were allocated to the mobile app, the in-person mindfulness-based program (IMBP), or a control group. Assessments at baseline and postintervention (8 weeks) included measures of anxiety, empathy, self-compassion, and mindfulness. Results Of 168 students randomised, 84 were analysed on an intention-to-treat basis (app: n = 31; IMBP: n = 23; control: n = 30). The mobile app group showed a large effect size for reductions in trait anxiety compared with controls (g = 0.85, p = 0.003), and a medium, nonsignificant effect compared with the IMBP group (g = 0.52, p = 0.152). Participants from both interventions experienced a significant increase in self-compassion and mindfulness compared with controls. Levels of empathy remained unchanged for the 3 arms. Conclusions A mobile app can be as effective as an IMBP in reducing anxiety and increasing self-compassion and mindfulness among healthcare students.

Examining the Effectiveness of Mindfulness Based Training Program on Female Handball Players’ Psychological Skills and Coping with Stress Strategies

The aim of this study is to examine the effectiveness of a mindfulness-based training program on female handball athletes’ psychological skills and strategies to cope with stress in sport. In the study, as a quasi-experimental method, pre-test, and post-test models without a control group were used. The study group consists of 9 female handball players who play in the Antalya Muratpasa Municipality Women's Handball Team. In the research, a personal information questionnaire, the Athletic Coping Skills Inventory and Coping Strategies in Sport Competition Inventory were used to collect data as pre-test before the program and as post-test at the end of the program. In the study, the Mindfulness-Based Training Program was implemented once a week as group training, consisting of 8 sessions lasted 60 minutes each. Wilcoxon Signed Rank Test was used to test the significance of the scope difference. As a result of the study, after the program, there was a significant difference in terms of ability to cope with adversity, coachability, concentration, goal setting and mental preparation, and being free from worries. Moreover, a significant difference between pre-test and post-test scores of the task-oriented coping dimension in Sport Competition Inventory was noted.

Online Mindfulness Training Increases Well-Being, Trait Emotional Intelligence, and Workplace Competency Ratings: A Randomized Waitlist-Controlled Trial.

A randomized waitlist-controlled trial was conducted to assess the effectiveness of an online 8-week mindfulness-based training program in a sample of adults employed fulltime at a Fortune 100 company in the United States. Baseline measures were collected in both intervention and control groups. Following training, the intervention group (N = 37) showed statistically significant increases in resilience and positive mood, and significant decreases in stress and negative mood. There were no reported improvements in the wait-list control group (N = 65). Trait mindfulness and emotional intelligence (EI) were also assessed. Following the intervention mindfulness intervention participants reported increases in trait mindfulness and increases on all trait EI facets with the exception of empathy. The control group did not report any positive changes in these variables, and reported reductions in resilience and increases in negative mood. Finally, both self and colleague ratings of workplace competencies were collected in the intervention group only and provided preliminary evidence that mindfulness training enhanced performance on key leadership competencies including competencies related to decisiveness and creativity. The present study demonstrates the effectiveness of an online-based mindfulness training program for enhancing well-being, self-perceptions of emotional intelligence, and workplace performance.

The effectiveness of mindfulness-based intervention on perceived stress and perception of disease in patients with acute coronary syndrome.

CONTEXT:One of the most important issues in patients with coronary artery disease is their mental health indices such as perceived stress and perception of disease.AIMS:The aim of this study was to evaluate the effectiveness of mindfulness-based intervention on the perceived stress and disease perception of patients with acute coronary syndrome.MATERIALS AND METHODS:This is a clinical trial, two-group, and three-stage study on 76 patients with acute coronary syndrome who were randomly divided into intervention and control groups. Nine weekly sessions of mindfulness-based training program were administered to the intervention group. The control group received routine services during this period. Data collection was done before, immediately, and 1 month after the intervention, using the Perceived Stress Scale and the Illness Perception Questionnaire. Data were analyzed using descriptive and inferential statistics.RESULTS:There was no significant difference between the mean scores of perceived stress and illness perception before intervention. After the intervention and 1 month after it, the mean score of perceived stress in the intervention group was statistically significantly lower than the control group (P < 0.001), and the perception of disease in the intervention group was statistically significantly higher than that of the control group (P < 0.001).CONCLUSIONS:It is worthwhile to suggest the mindfulness-based training program to reduce the perceived stress and correct the perception of disease for patients with acute coronary syndrome.

The Mutual Support Model of Mindfulness and Character Strengths

ObjectivesNumerous studies have confirmed robust relationships between general well-being and mindfulness or character strengths, respectively, but few have examined associations between mindfulness and character strengths. Two studies were carried out to explore these relationships comprehensively in the framework of the Values in Action (VIA) classification of character strengths.MethodsIn study 1, participants (N = 1335) completed validated assessments of mindfulness and character strengths, and the relationship between the two was investigated in a broad online sample. In study 2, the effect of a mindfulness training on specific character strengths was investigated using a randomized-control design (N = 42).ResultsThe results of study 1 confirmed positive relationships between mindfulness and character strengths and further identified a list of character strengths that might overlap with mindfulness—i.e., creativity, curiosity, open-mindedness, love of learning, perspective, bravery, perseverance, zest, love, social intelligence, forgiveness, self-regulation, appreciation of beauty, gratitude, hope, and spirituality. The findings of study 2 provided further support for the hypothesis that mindfulness training could help cultivate certain character strengths. Compared with participants in the waitlist control condition, those who attended an 8-week mindfulness-based training program showed significant increases in the strengths of love, appreciation of beauty, gratitude, and spirituality, and a trend toward significant increases in the strengths of zest and bravery.ConclusionsThe results provide initial evidence for a mutual support model of mindfulness and character strengths.

A REVIEW ON MINDFULNESS AND NURSING STRESS AMONG NURSES

&lt;p&gt;&lt;em&gt;Previous research has been done on mindfulness and nursing stress but no review has been done to highlight the most up-to-date findings, to justify the recommendation of mindfulness training for the nursing field. The present paper aims to review the relevant studies, derive conclusions, and discuss future direction of research in this field. A total of 19 research papers were reviewed. The majority was intervention studies on the effects of mindfulness-training programs on nursing stress. Higher mindfulness is correlated with lower nursing stress. Mindfulness-based training programs were found to have significant positive effects on nursing stress and psychological well-being. The studies were found to have non-standardized intervention methods, inadequate research designs, small sample size, and lack of systematic follow-up on the sustainability of treatment effects, limiting the generalizability of the results. There is also a lack of research investigation into the underlying mechanism of action of mindfulness on nursing stress. Future research that addresses these limitations is indicated.&lt;/em&gt;&lt;/p&gt;

Positive Effects of Mindfulness-Based Training on Energy Maintenance and the EEG Correlates of Sustained Attention in a Cohort of Nurses

Mindfulness based training (MBT) is becoming increasingly popular as a means to improve general wellbeing through developing enhanced control over metacognitive processes. In this preliminary study, we tested a cohort of 36 nurses (mean age = 30.3, SD = 8.52; 2 male) who participated in an 8-week MBT intervention to examine the improvements in sustained attention and its energetic costs that may result from MBT. Changes in sustained attention were measured using the psychomotor vigilance task (PVT) and electroencephalography (EEG) was collected both during PVT performance, and during a brief period of meditation. As there was substantial variability in training attendance, this variable was used a covariate in all analyses. Following the MBT program, we observed changes in alpha power across all scalp regions during meditation that were correlated with attendance. Similarly, PVT performance worsened over the 8-week period, but that this decline was mitigated by good attendance on the MBT program. The subjective energy depletion due to PVT performance (measured using self-report on Likert-type scales) was also less in regular attendees. Finally, changes in known EEG markers of attention during PVT performance (P300 and alpha-band event-related desynchronization) paralleled these behavioral shifts. Taken together, our data suggest that sustained attention and its associated costs may be negatively affected over time in the nursing profession, but that regular attendance of MBT may help to attenuate these effects. However, as this study contained no control condition, we cannot rule out that other factors (e.g., motivation, placebo effects) may also account for our findings.

Mindfulness-based stress reduction training program increases psychological well-being, and emotional regulation, but not attentional performance. A pilot study

Recently, several studies have suggested that mindfulness-based training programs are beneficial for well-being and emotional regulation. In this article an assessment is presented on the effects of a Mindfulness-Based Stress Reduction Training Program on the extent of mindfulness, psychological well-being, empathy levels, emotional regulation and neuropsychological functions. Results showed that the trained group significantly increased their observation and non-judgment of inner experience variables. The trained group also improved in subjective psychological wellness, and emotional regulation, but not in attentional performance. The relationships between the results obtained are discussed, and a new method is proposed for assessing the capacity for emotional regulation. Further studies are necessary using larger samples.

A Comparison of Mindfulness-Based Group Training and Skills Group Training in Adults With ADHD

Objective: To compare a novel “third wave” mindfulness-based training program with an established skills training derived from dialectical behavior therapy, to reduce ADHD symptoms and improve mindfulness and self-efficacy. Method: Ninety-one adults with ADHD (combined and inattentive type, mainly medicated) were non-randomly assigned to and treated within a mindfulness-based training group (MBTG, n = 39) or a skills training group (STG, n = 52), each performed in 13 weekly 2-hr sessions. Results: General linear models with repeated measures revealed that both programs resulted in a similar reduction of ADHD symptoms, and improvement of mindfulness and self-efficacy. However, the effect sizes were in the small-to-medium range. A decrease in ADHD symptoms ≥30% was observed in 30.8% of the MBTG participants and 11.5% of the STG participants. Conclusion: The comparatively weak results may be due to limitations such as the absence of randomization, the lack of a control group without intervention, and the lack of matching groups for borderline, depression, and anxiety status. Moreover, audio instructions for home exercises and more stringent monitoring of participants’ progress and eventual absence from sessions might have improved the outcome.
