(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, ω² = 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.

This article aims to better understand the mechanisms that connect climate change perceptions and general willingness to engage in pro-environmental behavior using Spanish cross-sectional data (N = 403) that included 102 members of environmental organizations. To do this, we first developed and validated the General Willingness for Environmental Behavior Scale (GWEBS), which includes the classical approach of voluntarily doing new actions but also actions implying not doing things (degrowth) and actions forced by social constraints. The exploratory and confirmatory factor analysis showed a good fit for the one-factor structure, which had adequate validity based on their relationship with other variables. Additionally, the GWEBS distinguished between women and men, left- and right-oriented people, and people who belonged to pro-environmental groups and people who did not. In the second place, we tested the parallel mediator role of eco-anxiety and trust in science in the relationship between climate change perceptions and the GWEBS. The results showed that eco-anxiety fully mediated and trust in science partially mediated such a relationship, making them crucial in terms of mobilizing the intention to act according to perceptions. This study contributes to understanding the psychological mechanisms that eventually drive pro-environmental behaviors and provides a clear direction for future research.

Climate change (CC) is one of the most urgent challenges of our time. Research suggests that pro-environmental behaviors (PEB) are essential to address this crisis, encompassing sustainable consumption (e.g., recycling or saving energy) and active participation (e.g., protesting or donating). In this regard, young adults play a significant role as change agents. Considering the previous literature affirming the importance of CC emotions on PEB, this study aims to analyze the mediating role of eco-worry and eco-anxiety in the relationship between two cognitive antecedents (general willingness to behave pro-environmentally and CC agency) and two types of PEB (sustainable consumption and active participation). To do so, we gathered a sample of 308 young adults aged 18 to 30 years. Results show that eco-worry mediates the relationships between both antecedents (willingness and CC agency) with sustainable consumption and active participation. In contrast, eco-anxiety in young adults only mediates the relationship between CC agency and active participation. Our findings suggest that eco-worry plays a crucial role in promoting PEB more broadly, while eco-anxiety appears to be only relevant in influencing active participation. These results contrast with others observed in the adult population, so further studies are needed to confirm these findings.

Scientific literature is keen to promote the study of eco-anxiety despite its current low prevalence and inconsistent relationships with pro-environmental behavior and mental health. In this paper, we analyze in a representative sample of the Spanish population (N = 1911) the incremental validity of the eco-worry construct concerning that of eco-anxiety at three levels of environmental commitment: high (environmental activists), medium (people who are not part of any environmental organization but who would like to), and low (people who neither belong to environmental groups nor want to). Our results showed that (1) the environmental activists in our sample did not seem to be eco-anxious but rather eco-worried, and (2) at the three levels of environmental commitment, eco-worry but not eco-anxiety positively mediated the relationship between climate change perception and general willingness for environmental behavior, and eco-worry, but not eco-anxiety, positively connected with life satisfaction through the general willingness to behave pro-environmentally. It is concluded that eco-anxiety does not add anything to the more intuitive and non-pathological concept of eco-worry, except for the alarm signal, which is not at all strategic when the goal is to promote individual pro-environmental behaviors and collective social actions.
