Effects of Mindfulness Meditation Intervention on Depressive Symptoms in Emerging Adults: A Systematic Review and Meta-Analysis

Acceptability, usage, and efficacy of mindfulness apps for college student mental health: A systematic review and meta-analysis of RCTs

BACKGROUND

Preventing anxiety and depression among college students is a pressing public health need. Recent meta-analyses have examined mobile mindfulness interventions in adult populations; however, college students are in a unique developmental stage and institutional setting.

METHODS

We conducted a systematic literature review and meta-analysis of published and unpublished studies in English language on the acceptability, usage, and efficacy of mindfulness training apps on mental health among non-clinical samples of college students. Out of 167 reviewed studies, 47 were included in the narrative review. Additionally, we summarized effects from 19 stress, 12 anxiety, 13 depression, and 8 emotional well-being trials (total N = 2974) using robust variance estimation meta-regression and evaluated certainty of evidence with the GRADE approach.

RESULTS

Apps were acceptable, with usage levels varying. They reduced stress by 0.435 standard deviation units, 95 % CI (-0.615,-0.255), and increased emotional well-being by 0.431 (0.162,0.7) approaching medium effect sizes. The apps had small effects on depression (B = -0.219 (-0.374, -0.065)) and anxiety (B = -0.218 (-0.42, -0.016)). Certainty of evidence was moderate for stress, depression, and well-being; and low-to-moderate for anxiety. Distressed participants had larger improvements in all outcomes except depression.

LIMITATIONS

Small sample sizes in the original studies and small numbers of studies limit the precision of our effect estimates. The small number of studies with objective usage data impedes our ability to characterize the optimal dose.

CONCLUSIONS

With moderate certainty of evidence, mindfulness training apps may improve student mental health with similar or larger effect sizes than in the general adult population. However, sustained usage may be a challenge, and more research is needed on the optimal implementation strategy, dose, and equity.

Combined cold-water immersion and breathwork may be associated with improved mental health and reduction in the duration of upper respiratory tract infection - a case-control study

A polar plunge is a term referring to an ice-cold water immersion (CWI), usually in the winter period. It is also a part of a specific training program (STP) which currently gains popularity worldwide and was proven to display paradigm-shifting characteristics. The aim of this study was to compare the indices of mental functioning (including depression, anxiety, mindfulness) and duration of upper respiratory tract infection (URTI) measured among the study participants. A set of questionnaires was distributed via the Internet. Participants declaring regular STP practice were selected (N = 77). Two groups were matched based on a case-control principle: the first one (the control group) comprised participants who did not declare nor CWI practice, nor STP practice. The second one comprised participants declaring regular CWI practice only. The CWI only group displayed better mental health indices and shorter URTIs compared to the control group. Moreover, the STP group also displayed better general mental health, less somatic complaints, and shorter URTIs compared to the CWI only group. This study suggests the existence of CWI's potential in boosting mental health and immune system functioning, however when complemented by a specific breathwork, this potential can be increased. However, further research is required.

Efficacy of a Mind Space Application intervention on psychological outcomes in Thai university students with depression: A pilot randomized controlled trial

OBJECTIVE

This purpose of this study is to evaluate the effects of the Mind Space Application on psychological outcomes among Thai-university students with depression.

METHOD

Thai-university students with depression (N = 50) were recruited between November 2021 and January 2022. Participants were randomly assigned to either an 8-week mindfulness-based intervention via the Mind Space Application intervention or a waitlist control group. Stress, anxiety, depression, and mindfulness were assessed at baseline and post-intervention.

RESULTS

Post-intervention, compared to waitlist control group, participants using the Mind Space Application reported large effects in the reduction of stress (d = 1.46, p < .001) and depression (d = 1.88, p < .001), small to moderate effects in reduction of anxiety (d = 0.35, p = .35), but no significant. Also, mindfulness scores were significantly higher (d = 1.90, p < .001) compared to the waitlist control group.

CONCLUSION

Thai-university students with depression who used the Mind Space Application showed lower stress and depression and higher mindfulness compared to the waitlist group among. Similar applications may be useful as an alternative or combined with other treatments to improve psychological outcomes in other university student populations.

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

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

Digitally Assisted Mindfulness in Training Self-Regulation Skills for Sustainable Mental Health: A Systematic Review

The onset of the COVID-19 pandemic has led to an increased demand for mental health interventions, with a special focus on digitally assisted ones. Self-regulation describes a set of meta-skills that enable one to take control over his/her mental health and it is recognized as a vital indicator of well-being. Mindfulness training is a promising training strategy for promoting self-regulation, behavioral change, and mental well-being. A growing body of research outlines that smart technologies are ready to revolutionize the way mental health training programs take place. Artificial intelligence (AI); extended reality (XR) including virtual reality (VR), augmented reality (AR), and mixed reality (MR); as well as the advancements in brain computer interfaces (BCIs) are ready to transform these mental health training programs. Mindfulness-based interventions assisted by smart technologies for mental, emotional, and behavioral regulation seem to be a crucial yet under-investigated issue. The current systematic review paper aims to explore whether and how smart technologies can assist mindfulness training for the development of self-regulation skills among people at risk of mental health issues as well as populations with various clinical characteristics. The PRISMA 2020 methodology was utilized to respond to the objectives and research questions using a total of sixty-six experimental studies that met the inclusion criteria. The results showed that digitally assisted mindfulness interventions supported by smart technologies, including AI-based applications, chatbots, virtual coaches, immersive technologies, and brain-sensing headbands, can effectively assist trainees in developing a wide range of cognitive, emotional, and behavioral self-regulation skills, leading to a greater satisfaction of their psychological needs, and thus mental wellness. These results may provide positive feedback for developing smarter and more inclusive training environments, with a special focus on people with special training needs or disabilities.

A self-management plus mind body intervention for adolescents and young adults with type 2 diabetes: Trial design and methodological report

BACKGROUND

The onset of type 2 diabetes (T2D) is increasingly common in adolescents and young adults (AYAs). Improving self-management skills and the mental health of this population is important, but understudied.

METHODS

The goal of this research was to develop a mind-body intervention which could serve as an adjunctive therapy to support AYAs with T2D (INTEND intervention). Toward that end, we used an iterative process, including use of focus groups, advisory board, and cognitive semi-structured interviews with patients, parents of patient and clinical providers, to understand the gaps in the current information provided to AYAs with T2D. Based on the data gathered from the focus groups and interviews, we enhanced an existing self-management intervention for adults with T2D to include an additional mind body intervention for AYAs with T2D. The INTEND intervention will be piloted in a group of AYAs with T2D.

RESULTS

This report describes the methodology and design of the InterveNTion for Early oNset type 2 Diabetes (INTEND) study. The details of this single arm pre-post pilot feasibility trial are described.

DISCUSSION

If successful, the INTEND approach has the potential to advance care for vulnerable youth with T2D.

The mediating effects of social support and depressive symptoms on activities of daily living and social frailty in older patients with chronic heart failure

OBJECTIVES

To investigate the level of social frailty (SF) in older patients with chronic heart failure (CHF) and examine the mediating role of social support and depressive symptoms between activities of daily living and SF.

METHODS

Using a convenience sampling method, 205 older patients with CHF were recruited from China between November 2021 and May 2022. Activities of daily living, social support, depressive symptoms, and SF were assessed using a self-administered questionnaire. Data were analyzed using structural equation modeling.

RESULTS

The final model obtained a good fit. Activities of daily living in older patients with CHF were directly related to SF. The multiple mediation analysis revealed that the relationship between activities of daily living and SF was mediated by social support (effect: -0.010, 95% CI [-0.021, -0.003]) and depressive symptoms (effect: -0.011, 95% CI [-0.019, -0.005) separately, and serially (effect: -0.007, 95% CI [-0.012, -0.003).

CONCLUSIONS

Social support and depressive symptoms are multiple mediating variables in the relationship between activities of daily living and SF. Activities of daily living can improve patients' SF through social support and depressive symptoms.

Person-Centered Mindfulness: A Culturally and Spiritually Sensitive Approach to Clinical Practice

Mindfulness meditation is rapidly being integrated into many different forms of counseling and psychotherapy, and there is a growing evidence base for its effectiveness. It is important to understand the spiritual roots of mindfulness, and to apply it in a patient-centered manner, sensitive to the patient's own faith tradition rather than taking a one-size-fits-all approach, assuming that mindfulness-based practice is a purely secular approach. The philosophical underpinning of mindfulness lies squarely in the Buddhist faith tradition. Indeed, mindfulness is the 7th step on the Eightfold Path, which is the heart of Buddhist teachings. Many practitioners, however, may not realize that there are Western meditative techniques that are very similar to mindfulness and that have deep roots within Christian, Jewish, and Muslim faith traditions. Patient-centered mindfulness involves the use of mindfulness and other meditation methods that are based on the patient's own faith tradition, rather than applying Eastern forms of mindfulness claiming these are a secular approach appropriate for everyone regardless of religious beliefs, even if those beliefs are not consistent with the Buddhist religious or philosophical approach. In this article, I briefly examine the evidence for the clinical effectiveness of mindfulness meditation, and then go into greater depth on Hindu, Buddhist, Christian, Jewish, and Muslim forms of mindfulness or similar meditative practices, providing resources that will better equip clinicians and researchers to provide patient-centered culturally-sensitive care.

Effects of a Virtual Reality-Based Meditation Intervention on Anxiety and Depression Among Patients With Acute Leukemia During Induction Chemotherapy: A Randomized Controlled Trial

BACKGROUND

Emerging evidence supports that virtual reality (VR)-based meditation interventions may improve anxiety and depression among patients with cancer. However, empirical studies involving patients with acute leukemia during induction chemotherapy are limited.

OBJECTIVE

This study aimed to examine the effects of VR-based meditation intervention on alleviating anxiety and depression and improving the quality of life among patients with acute leukemia during induction chemotherapy.

METHODS

This randomized controlled trial recruited 63 patients newly diagnosed with acute leukemia. Participants were randomly assigned to an intervention group (received VR-based meditation for 20 min daily for 14 days) and a control group. Anxiety, depression, and quality of life were measured using the State Anxiety Inventory, the Center for Epidemiological Studies Depression Scale, and the Functional Assessment of Cancer Therapy-Leukemia Questionnaire, respectively. All outcomes were measured at baseline and post-intervention.

RESULTS

Compared with patients in the control group, those in the intervention group demonstrated a significantly greater reduction in anxiety (P = .04) and improvement in quality of life (P = .04). However, no significant difference was noted in depression levels between groups (P = .09), although a decreasing trend was observed in the intervention group.

CONCLUSION

Virtual reality-based meditation intervention effectively alleviated anxiety and improved the quality of life among acute leukemia patients during induction chemotherapy. Future randomized controlled trials with larger sample sizes and longer follow-up periods are warranted.

IMPLICATION FOR PRACTICE

Virtual reality-based meditation can be applied in clinical practice virtually anytime and anywhere to provide a convenient intervention for anxiety reduction for acute leukemia patients during induction chemotherapy.

Feasibility of a meditation intervention for stroke survivors and informal caregivers: a randomized controlled trial

BACKGROUND

Depressive symptoms are a significant psychological complication of stroke, impacting both survivors and informal caregivers of survivors. Randomized controlled trials are needed to determine optimal non-pharmacological strategies to prevent or ameliorate depressive symptoms in stroke survivors and their informal caregivers.

METHODS

A prospective, randomized, parallel-group, single-center, feasibility study. Participants were assigned to a 4-week meditation intervention or expressive writing control group. The intervention comprised four facilitator-led group meditation sessions, one session per week and building upon prior session(s). Descriptive statistics were used to examine the proportion of eligible individuals who enrolled, retention and adherence rates, and the proportion of questionnaires completed. Data were collected at baseline, immediately after the 4-week intervention period, and 4 and 8 weeks after the intervention period. Secondary analysis tested for changes in symptoms of depression (Center for Epidemiologic Studies-Depression [CES-D]), anxiety [State-Trait Anxiety Inventory for Adults (STAI)], and pain (Brief Pain Inventory-Short Form) in the intervention group via paired t tests. Linear mixed models were used to compare longitudinal changes in the measures between the groups. Intervention and trial design acceptability were preliminary explored.

RESULTS

Seventy-one (77%) individuals enrolled and 26 (37%) completed the study (baseline and 8-week post-intervention visits completed). Forty-two (66%) participants completed baseline and immediate post-intervention visits. Mean questionnaire completion rate was 95%. The median meditation group session attendance rate for the intervention group was 75.0%, and the mean attendance rate was 55%. Non-significant reductions in CES-D scores were found. Paired t tests for stroke survivors indicated a significant reduction from baseline through week 8 in BPI-sf severity scores (p = 0.0270). Repeated measures analysis with linear mixed models for informal caregivers indicated a significant reduction in in STAI-Trait scores (F [3,16.2] = 3.28, p = 0.0479) and paired t test showed a significant reduction from baseline to week 4 in STAI-Trait scores (mean = - 9.1250, 95% CI [- 16.8060 to 1.4440], p = 0.0262). No between-group differences were found.

CONCLUSIONS

Future trials will require strategies to optimize retention and adherence before definitive efficacy testing of the meditation intervention.

The Impact of One-Time Relaxation Training on Attention Efficiency Measured by Continuous Performance Test in Depressive Disorders

Introduction: People with depression often complain of dysfunction in cognitive processes, particularly attention. Pharmacotherapy is one of the most commonly used methods of treating depressive disorders and related attention difficulties. Patients also benefit from various forms of psychotherapy and frequently support themselves with alternative therapeutic methods. The purpose of this study was to examine whether a 15-min-long relaxation training session could improve the efficiency of attention and perceptiveness in individuals diagnosed with depressive disorders. Methods: Forty-two individuals participated in the study, including 20 individuals diagnosed with recurrent depressive disorder (rDD) and 22 healthy subjects (comparison group, CG). The so-called continuous performance test in the Polish version (Attention and Perceptiveness Test, APT) was applied in the study. In the first stage, the participants completed the 6/9 version of the APT test and then took part in a 15-min relaxation training session (autogenic training developed by the German psychiatrist Johannes Heinrich Schultz). The next step of the study was to perform APT again (parallel version—3/8). Results: The analyses showed statistically significant differences (p < 0.001) in the results obtained in the two versions of APT between the studied groups (rDD versus CG) in terms of the perceptual speed index. These differences were seen both before and after the introduction of the relaxation training. There was a statistically significant difference in the value of the perceptual speed index before and after the applied relaxation training for the subjects with depression (p = 0.004) and for the whole study group (p = 0.008). A significant correlation of illness symptom severity with decreased attentional efficiency was observed in the rDD group (perceptual speed index)—both before (r = −0.864; p < 0.001) and after the relaxation training (r = −0.785; p < 0.001). Conclusions: The continuous performance test (APT) is a reliable indicator of impaired attention efficiency among patients with depressive symptoms compared to healthy subjects. 15-min-long one-time relaxation exercise has a beneficial effect on attention efficiency measured by APT in people with depression.
