(1) Background: There is increasing interest in the practice of mindfulness-based interventions (MBIs) to treat people with schizophrenia, as evidenced by the publication of different randomized controlled trials (RCTs). However, no meta-analysis of RCTs has been carried out to date with the exclusive inclusion of this type of interventions. (2) Objective: To analyze empirical evidence regarding the effectiveness of MBIs for the improvement of clinical parameters associated with schizophrenia. Method: A systematic review and meta-analysis was conducted of RCTs published in the databases PsycINFO, PubMed, WOS, and Cochrane Library. (3) Results: A total of 10 articles (n = 1094) fulfilled the criteria for inclusion in the review. The analysis of these studies suggests that MBIs combined with standard interventions are able to generate significant improvements in a variety of clinical schizophrenia-related parameters, such as the intensity of overall symptomatology (g = 0.72), positive symptoms (g = 0.32), negative symptoms (g = 0.40), functioning level (g = 1.28), and awareness of illness (g = 0.65). (4) Conclusions: There is evidence that supports the effectiveness and safety of MBIs for the treatment of people with schizophrenia. The results obtained by MBIs are comparable to those obtained by cognitive-behavioral therapy for psychosis. However, given the heterogeneity of the applied interventions and the methodological limitations found in the reviewed trials, the results should be interpreted with caution.

This research analyses the effects of mindfulness meditation (MM) and physical exercise (PE), practised as daily recovery activities during lunch breaks, on perceived stress, general mental health, and immunoglobin A (IgA). A three-armed randomized controlled trial with 94 employees was conducted for five weeks including two follow-up sessions after one and six months. Daily practice lasted 30 min maximum. Perceived stress and general mental health questionnaires and saliva samples were used. There were significant differences in time factor comparing pre-and post-test of Perceived Stress Questionnaire (PSQ) both for PE [Mdiff = 0.10, SE = 0.03, p = 0.03], and for MM [Mdiff = 0.09, SE = 0.03, p = 0.03]. Moreover, there were significant differences of interaction factor when comparing MM vs. PE in total score at pre-post [F = −2.62 (6, 168.84), p = 0.02, ω 2 = 0.09], favoring PE with medium and high effect sizes. Regarding General Health Questionnaire (GHQ) variable, practicing MM showed significant effects in time factor compared to pre-Fup2. No significant differences were found for IgA. Thus, practicing both MM and PE as recovery strategies during lunch breaks could reduce perceived stress after five weeks of practice, with better results for PE. Moreover, practicing MM could improve mental health with effects for 6 months.for conducting research on immune function [15][16][17]. Nevertheless, the relationship between sIgA responses and stressors is not linear, since sIgA increases as a response to both relaxation and stressors [18,19]. Therefore, it has been proposed that acute stress may potentially enhance the immune system as an adaptive response [20], while chronic stress produces a decline in immune functioning, associated with high susceptibility to infectious diseases [21,22].Work and workplace-related issues are common sources of stress [23]. Work-related stress is associated with a decrease in productivity, increased absenteeism, accidents and injuries, mental illness, increased errors and poor performance, conflictive relations, somatic symptom disorders and even alcohol and drug abuse [24]. According to the International Labour Organization (2016) [25], stress is responsible for 30% of all work-related disorders. In the European Union, workplace stress has a negative impact on the wellbeing of 22% of the total labour force [26] and these data are expected to rise in the future [27,28].All this implies significant financial costs to society. In the European Union, the cost of work-related depression is estimated at € 617 billion a year, including costs to employers resulting from absenteeism and presenteeism (€ 272 billion), loss of productivity (€ 242 billion), health care costs (€ 63 billion) and social welfare costs due to disability benefit payments (€ 39 billion) [29].In this context, it seems crucial to find effective solutions. Sometimes, employees seek help to develop stress management strategies through psychotherapy, training courses, effective communication techniques, social support and re...

Aim: This paper aims to investigate the extent to which mindfulness-based interventions serve to reduce anxiety in children and adolescents. A heterogeneous sample was used, including clinical and non-clinical population. Methods: A literature search of controlled intervention studies published up to December 31, 2016, was carried out in PubMed, Lilacs, Cochrane, Embase, PsycInfo, Opengrey and Teseo databases. The effect size was calculated by Cohen's d. The Cochran Q statistic and the I 2 index were used for the study of heterogeneity. An analysis was conducted using the random effects model. Results: 829 articles were identified, of which 18 were finally selected. Of these, only three had statistically significant effect sizes. The overall combined result obtained was .013, but it did not result statistically significant (CI95% [−.102, .128].) The Q statistic was statistically significant (Q [18] = 28.497, P = . 39) and the I 2 index was 40.34%, indicating a moderate heterogeneity.Conclusions: This meta-analysis did not obtain statistically significant results that could provide conclusions. In general, the studies analysed are small, of low power and have a marked heterogeneity, which implies that the findings are provisional and need to be supported by more robust studies.Although it cannot be ruled out that mindfulness-based interventions are not effective in the infant-juvenile population, it is also possible that this effect could not be detected due to the limited number of available studies. Larger investigations are needed, with sufficient statistical power and designs that control the variables potentially moderating, to establish clear conclusions.

Mindfulness-based interventions (MBIs) consist of short and structured intervention protocols focused on teaching patients the use of mindfulness for therapeutic purposes. Over the last three decades, there has been a remarkable expansion of this kind of interventions for the treatment of various psychopathological conditions. Despite this, MBIs have only recently begun to be applied in the treatment of people with schizophrenia. Analysis of the available evidence on MBIs for the treatment of people with this disorder suggests that they are effective and safe treatments, although more research is needed to draw more robust conclusions.  

Cognitive‐behavioural therapy for insomnia (CBT‐I) is the recommended first‐line therapy for adults with chronic insomnia disorder (ID), which is characterized by hyperarousal. Mindfulness‐based interventions (MBIs) are protocols aimed at stress reduction based on non‐judgmental attention control in the present moment. However, MBIs have been increasingly used without a clear scientific basis. The objective of this analysis was to examine if MBIs could be useful as a component of the CBT‐I therapeutic system through a systematic review and meta‐analysis of randomized controlled trials (RCTs) and non‐randomized studies (NRS) searched in PubMed, PsycINFO, Cochrane and WoS. The Insomnia Severity Index (ISI) was the primary outcome, while the Pittsburgh Sleep Quality Index (PSQI) and a composite sleep variable (CSV) were secondary outcomes. Thirteen articles corresponding to nine studies (three pragmatic RCTs, three explanatory RCTs and three NRS) were included. The omnibus test found that MBIs had a small to medium effect size on ISI nearing signification when comparing active control groups in the pretest–posttest period [Δ = 0.44, p = 0.07], a medium, non‐significant, effect size on PSQI [Δ = 0.52, p = 0.18], and a significant though small effect size on CSV [Δ = 0.05, p < 0.01]. No heterogeneity was found. The analysis could not demonstrate that MBIs, combined with CBT‐I components in some studies, positively affected ID in the general adult population. This was probably due to the lack of pragmatic designs and suitable measuring instruments. Recommendations are made for designing further studies to address these issues.
