Review
Several recent studies have explored the relationships between mindfulness and time perception, an area of research that has become increasingly popular in the last 10-15 years. In this article, we present a systematic integrative review of the evidence on this subject. We also integrate the field's findings into a conceptual framework which considers the multifaceted nature of both mindfulness, and time perception research. To identify the relevant literature, we searched the following databases using relevant keywords: PsycINFO; Medline; EBSCO Host Psychology and Behavioral Sciences Collection; and Web of Science. These searches were last performed on the 4th of May 2022, and additional hand searches were also conducted. To be included, articles had to be in English and contain original data about the potential relationship(s) between mindfulness and time perception. Articles which did not present usable data about the relationship(s) between the variables of interest were excluded. In total, 47 research articles were included in the review (combined sample size of ∼5800 participants). Risks of bias in the selected studies were evaluated using two separate assessment tools designed for this purpose. Through an integrative narrative synthesis, this article reviews how mindfulness may relate to time perception for various reference frames, and for various time perception measures and methods. It also provides new insights by exploring how a wide range of findings can be integrated into a coherent whole, in light of some relevant time perception models and mindfulness theories. Altogether, the reviewed data suggest the existence of complex and multifaceted relationships between mindfulness and time perception, highlighting the importance of considering many factors when planning research or interpreting data in this field. Limitations of the current review include the scarceness of data for certain categories of findings, and the relatively low prevalence of studies with a randomized controlled design in the source literature. This research was partly funded by a grant from the Natural Science and Engineering Research Council of Canada.

Review
Human development implies deep changes in cognitive, attentional, emotional, and behavioral skills. Therefore, Mindfulness-Based Interventions (MBIs) should be adapted in terms of dose, frequency, kind of exercises, assessment methods, and expected effects regarding the abilities and limitations of each developmental period. The present review seeks to describe and compare MBIs characteristics, assessment methods, and effects in youth between 3 and 18 years old considering four developmental periods. A systematic review was carried out including experimental primary studies published during the last five years. Results show that the frequency of the sessions and program duration varies widely. Differences were observed in instructors' training and in assessment strategies. Discrepancies were observed regarding the effects of MBIs both within and between periods in cognitive, socio-emotional, symptoms, and mindfulness variables. Consistency was observed in prosocial behaviors for preschoolers, and in emotional and behavioral problems and hyperactivity in ages between preschool and early adolescence. Nevertheless, it was impossible to compare most results and determine consistency or discrepancy due to the lack of studies. Regarding mindfulness, it is defined and assessed in different ways in each period. Orientations are suggested to move from a compartmentalized view of isolated MBIs, towards an integrative perspective that allows tracing developmental trajectories for mindfulness and other key cognitive and socioemotional skills for children and adolescents.

Review
Moderate-to-severe pain is a common problem experienced by patients with cancer. Although analgesic drugs are effective, adverse side effects are common and some analgesic drugs are addictive. Nonpharmacological treatment may be a way to treat cancer pain without causing negative side effects. Mindfulness is used as an effective nonpharmacological treatment to improve quality of life (QoL) and to address psychological problems including distress, anxiety, stress, and depression. However, the effect of mindfulness on pain severity has not been sufficiently investigated. Therefore, a systematic review was undertaken to describe the effectiveness of mindfulness interventions for pain and its underlying pathophysiologic mechanisms. The search was conducted in PubMed, Ovid MEDLINE, and CINAHL and included only empirical studies published from 2008 to 2017. Search terms included mindfulness, mindfulness-based intervention, meditation, cancer, pain, and cancer-related pain. Six studies met the search criteria. These studies tested several types of intervention including mindfulness-based stress reduction, mindfulness-based cognitive therapy, meditation with massage, and mindful awareness practices. Study outcomes include improved pain severity, anxiety, stress, depression, and QoL. However, most studies reviewed were conducted in the United States and Denmark. Further research is needed to test culturally appropriate mindfulness interventions to reduce pain.

JMIR Mental Health Sep 2018Web-based mindfulness interventions are increasingly delivered through the internet to treat mental health conditions. (Review)
Review
BACKGROUND
Web-based mindfulness interventions are increasingly delivered through the internet to treat mental health conditions.
OBJECTIVE
The objective of this study was to determine the effectiveness of web-based mindfulness interventions in clinical mental health populations. Secondary aims were to explore the impact of study variables on the effectiveness of web-based mindfulness interventions.
METHODS
We performed a systematic review and meta-analysis of studies investigating the effects of web-based mindfulness interventions on clinical populations.
RESULTS
The search strategy yielded 12 eligible studies. Web-based mindfulness interventions were effective in reducing depression in the total clinical sample (n=656 g=-0.609, P=.004) and in the anxiety disorder subgroup (n=313, g=-0.651, P<.001), but not in the depression disorder subgroup (n=251, P=.18). Similarly, web-based mindfulness interventions significantly reduced anxiety in the total clinical sample (n=756, g=-0.433, P=.004) and the anxiety disorder subgroup (n=413, g=-0.719, P<.001), but not in the depression disorder group (n=251, g=-0.213, P=.28). Finally, web-based mindfulness interventions improved quality of life and functioning in the total sample (n=591, g=0.362, P=.02) in the anxiety disorder subgroup (n=370, g=0.550, P=.02) and mindfulness skills in the total clinical sample (n=251, g=0.724, P<.001).
CONCLUSIONS
Results support the effectiveness of web-based mindfulness interventions in reducing depression and anxiety and in enhancing quality of life and mindfulness skills, particularly in those with clinical anxiety. Results should be interpreted with caution given the high heterogeneity of web-based mindfulness interventions and the low number of studies included.

Review
BACKGROUND
Mindfulness-based cognitive therapy and isometric exercise training (IET) interventions are relatively new approaches to maintain physical functioning, alleviate pain, prevent joint stiffness and muscular atrophy, and positively influence other postoperative care outcomes.
OBJECTIVE
The aim of this review was to identify the impacts of mindfulness-based interventions (MBIs) and IET and, more specifically, their combination, which have not previously been assessed to our knowledge.
METHODS
Studies were identified by searching the PubMed and Cochrane databases within the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) algorithm format and using relevant keyword combinations, which resulted in 39 studies meeting the inclusion criteria.
RESULTS
In general, MBI was shown to positively impact both pain relief and physical functioning, while IET positively impacted physical functioning. Numerous other benefits, including improved quality of life and decreased postoperative opioid use, were also described from both interventions; however, further research is needed to confirm these findings as well as to determine other possible benefits. No studies were found that combined MBI and IET.
CONCLUSIONS
Despite many positive results from each individual intervention, there is a lack of information about how the combination of MBI and IET might impact postoperative care. The combination of these two interventions might prove to be more effective than each individual intervention alone, and the findings from this review show that they could even be complementary. Going forward, research should be expanded to study the possible benefits of the combination of MBI and IET in postoperative care routines as well as other possible combinations.

Review
There is evidence that mindfulness-based interventions (MBI) can help one to recover from mental fatigue (MF). Although the strength model of self-control explains the processes underlying MF and the model of mindfulness and de-automatization explains how mindfulness training promotes adaptive self-regulation leading to the recovery of MF, a systematic overview detailing the effects of MBI on the recovery of MF is still lacking. Thus, this systematic review aims to discuss the influences of MBI on the recovery of MF. We used five databases, namely, PubMed, Web of Science, EBSCOhost, Scopus, and China National Knowledge Infrastructure (CNKI) for articles published up to 24 September 2021, using a combination of keywords related to MBI and MF. Eight articles fulfilled all the eligibility criteria and were included in this review. The MBI directly attenuated MF and positively affected the recovery of psychology (attention, aggression and mind-wandering) and sports performance (handgrip, plank exercise and basketball free throw) under MF. However, the interaction did not reach statistical significance for the plank exercise. Therefore, the experience and duration of mindfulness are necessary factors for the success of MBI. mindfulness appears to be most related to a reduction in MF. Future research should focus on improving the methodological rigor of MBI to confirm these results and on identifying facets of mindfulness that are most effective for attenuating MF.

This evidence map presents a summary of studies that addressed the effects of meditation on various clinical and health conditions. Meditation is a contemplative practice that has been used for the promotion of health, and the treatment of different conditions. The study is based on the search of four electronic databases for the period 1994-November 2019 and includes systematic reviews, meta-analyses, meta-syntheses, and integrative reviews. 3iE evidence gap map was the methodology of choice, and AMSTAR 2 was used for the analyses. Tableau was used to graphically display the confidence level, number of reviews, health outcomes, and intervention effects. This map encompasses 191 studies, with Mindfulness being the key word that retrieved the highest number of results. Several meditation techniques were evaluated in different contexts, and the confidence levels of 22 studies were high, 84 were moderate, and 82 were low. Two 2 meta-syntheses and 1 integrative review were also included. Most of the studies reported positive effects and a beneficial potential of the practice of meditation. Health outcomes were divided into five groups out of which mental health and vitality, and well-being and quality of life stood out with the largest number of studies. Meditation has been applied in different areas. This Evidence Map intends to be an easy visual tool to access valuable evidence-based information on this complementary therapy for patients, health professionals, and managers.

Meta-Analysis
This review aims to identify, appraise, and synthesize studies reporting the relationship between mindfulness and athlete burnout and the effects of mindfulness-based interventions (MBIs) on athlete burnout. Studies were identified through searching six electronic databases using combinations of three groups of keywords and manual search. Two independent reviewers screened the searched studies, extracted data of the included studies, and assessed the study quality. The extracted data were synthesized qualitatively and quantitatively. Ten studies consisting of two controlled trials, six surveys, and two interview studies met the inclusion criteria. The two controlled trials had weak methodological quality, and the remaining studies were of moderate to high research quality. Results of controlled trials and interview research generally showed that MBIs had positive effects in burnout prevention. Meta-analytic results indicated a negative association between mindfulness and burnout. There is some evidence showing that mindfulness was negatively associated with athlete burnout. However, given the small number of interventions and qualitative studies, there is limited evidence on whether MBIs are useful in preventing athlete burnout. More studies are needed to corroborate these findings.

Review
BACKGROUND
Mindfulness-based Cognitive Therapy (MBCT) is a relapse-prevention intervention for people experiencing major depression. Three qualitative meta-syntheses investigating experiences of taking part in MBCT and/or Mindfulness-based Stress Reduction (MBSR) across different diagnostic populations reported themes including control, choice, group processes, relationships and struggles. As multiple studies have been published since, we aimed to update, systematically review and synthesize the experiences of participants with depression taking part in MBCT.
METHODS
Four databases were searched systematically (PsycInfo, Web of Science, Medline and CINAHL) up to and including 12 November 2021. Twenty-one qualitative studies met the review criteria. All papers were rated as fair using a quality appraisal tool. Meta-ethnography was applied.
RESULTS
Across 21 studies of participants with current or previous depression who had participated in MBCT, three overarching themes were developed: 'Becoming skilled and taking action', 'Acceptance' and 'Ambivalence and Variability'. Participants became skilled through engagement in mindfulness practices, reporting increased awareness, perspective and agency over their experiences. Participants developed acceptance towards their experiences, self and others. There was variability and ambivalence regarding participants' expectations and difficulties within mindfulness practices.
LIMITATIONS
Many studies were conducted in MBCT-research centres that may hold conflicts of interest. Many studies did not address the impact of the participant-researcher relationship thus potentially affecting their interpretations. Studies were skewed towards the experiences of female participants.
CONCLUSIONS
Our findings help to enhance participant confidence in MBCT, alongside understanding the processes of change and the potential for difficulties. MBCT is beneficial and provides meaningful change for many but remains challenging for some.

OBJECTIVE
Bodily distress, i.e., somatoform disorders and associated functional somatic syndromes, is highly prevalent, often persistent and highly disabling. It has been proposed that "third wave" therapies may be beneficial variants of cognitive behavioral treatments. However, evidence on their efficacy is scarce. This meta-analysis examines the efficacy of "third wave" psychotherapies (mindfulness-based cognitive therapy [MBCT], mindfulness-based stress reduction [MBSR], and acceptance and commitment therapy [ACT]) in adults with bodily distress.
METHOD
We included randomized controlled trials (RCTs) treating adults with bodily distress using MBCT, MBSR, and ACT compared to inactive and non-specific control groups. A random effects model was used. The primary outcome was somatic symptom severity. Secondary outcomes were degrees of depression and of anxiety, health anxiety, perceived health status, mindfulness, psychological inflexibility, and pain acceptance.
RESULTS
Sixteen RCTs with 1,288 participants were included in the analysis ( = 4 MBCT, = 7 MBSR, = 5 ACT; = 7 fibromyalgia, = 5 irritable bowel syndrome, = 1 chronic fatigue syndrome, = 2 bodily distress, = 1 medically unexplained symptoms). However, not all studies provided data for each of the relevant outcomes. The analyses revealed that "third wave" therapies were more effective than control conditions in reducing somatic symptom severity ( = 15, = 1,100, = -0.51, 95%CI -0.69; -0.32). Heterogeneity was moderate ( = 52.8%, 95%CI 15.1 to 73.8). Effects for secondary outcomes were small to moderate with varying degrees of heterogeneity. We did not find differences between the different therapy approaches (mindfulness- vs. acceptance-based therapies); neither therapy dosis (i.e., total duration of therapy sessions) nor number of sessions were significant moderators of efficacy.
CONCLUSIONS
The therapies addressing mindfulness and acceptance proved to be more effective than control conditions. Hence, they are promising treatment approaches for bodily distress. However, there is still need for research on which patient groups may benefit from these psychological approaches.
