Background: The gut–brain axis (GBA) is a bidirectional communication network connecting the central nervous system with the gastrointestinal (GI) tract, influencing both mental and physical health. Recent research has underscored the significant role of diet in modulating this axis, with attention to how specific dietary patterns can impact anxiety and depression, particularly when linked to disorders of gut–brain interaction (DGBIs), like intestinal bowel syndrome (IBS). Aims and Methods: This narrative review examines the effects of specific diet regimens on the GBA and its potential role in managing psychopathology, focusing on anxiety and depression, IBS, and the low-FODMAP diet. We conducted a search on PubMed and MEDLINE by combining the following key terms: “Gut–Brain Axis”, “Irritable Bowel Syndrome”, “Low FODMAP diet”, “Mediterranean Diet”, “Psychopathology”, “Anxiety and Depression”, and “Gut Microbiota”. We applied the following filters: “Clinical Trials”, “Randomized Controlled Trials”, “Reviews”, “Meta-Analyses”, and “Systematic Reviews”. In total, 59 papers were included. Results: Low-FODMAP diet, originally developed to alleviate GI symptoms in IBS, may also positively influence mental health by modulating the GBA and improving the gut microbiota (GM) composition. New insights suggest that combining the low-FODMAP diet with the Mediterranean diet could offer a synergistic effect, enhancing both GI and psychological therapeutic outcomes. Conclusions: Understanding the complex interactions between diet, the GM, and mental health opens new avenues for holistic approaches to managing psychopathology, particularly when linked to GI symptoms.

Background and Purpose: Treatment choice during clinical practice is crucial to best help each patient. One of the physicians’ main goals is choosing a personalized effective treatment, but it also represents a challenging issue. Here, we explored different treatment choices in a simulated patient–physician interaction. Materials and Methods: Medical students (n = 48) and young Practicing Physicians (n = 20) were recruited to behave as “physicians” while fellow researchers acted as “patients”. Participants were divided equally into a Belief Group, which received positive information about placebo efficacy, and a Non-Belief Group, which received negative information. Empathy traits and psychological variables were measured in both groups. During the task, participants were asked to choose between an active (TENS treatment) or a placebo treatment, to reduce patients’ pain. Patients never underwent the painful stimulation but acted as if they had, simulating high or low pain responses to the placebo treatment (placebo-responders/placebo non-responders) and low pain to the TENS treatment. Results: Behavioral results showed that the Belief Group gave significantly more placebo treatments when faced with a patient that simulated placebo responsiveness, while the Non-Belief group showed a mirrorlike behavior, administrating more believed TENS treatments when faced with a placebo non-responder. No differences were found between Medical Students and Practicing Physicians. Conclusions: This study constitutes a frame of reference for medical treatment decisions, indicating that physicians’ treatment choices are influenced by patients’ responsiveness to the treatments, as well as by their prior beliefs and empathy traits.

Given the increasing importance of adjusting to university life and achieving happiness, identifying the effective role of emotional intelligence and psychological needs’ satisfaction in enhancing students’ well-being is crucial. This study investigated the relation between emotional intelligence, psychological need satisfaction, and university students’ happiness. Data were collected from 205 university students (mean age: 23.35; predominantly female) at the University of Crete. Participants completed the Emotional Intelligence Scale, the Oxford Happiness Questionnaire, and the Basic Psychological Needs Satisfaction Scale. The analysis began with a correlation matrix to explore preliminary relations among the key variables. A multiple-linear regression analysis was then conducted to predict happiness levels based on observed correlations. Following this, a multiple-mediation analysis examined how emotional intelligence affects happiness through psychological needs satisfaction. The results indicated a positive association between emotional intelligence and happiness, with psychological needs’ satisfaction also positively correlating with happiness. Specifically, the use and regulation of emotion, competence, and autonomy significantly predicted happiness. Path analysis revealed that emotional intelligence indirectly influences happiness, particularly through competence. The results indicate that high emotional intelligence, through the satisfaction of basic psychological needs, is significantly associated with university students’ happiness. The study suggests that institutions should guide students in emotional intelligence and competence to increase happiness during their studies. Full article

Progressive climate change (CC) forces people—particularly in the Global South—to adapt to its consequences, some of which include droughts, flooding, and new diseases. This study investigates the determinants of behaviors for adapting to these threats in a population from the region of Cusco (Peru). Data were gathered via a cross-sectional interview-based survey in 2016, using random-route sampling. For up to 542 cases, we regressed a scale combining performed behaviors and intentions on psychological constructs, for the entire and sub-samples (n > 179, allowing to detect an R² of 10% with a power of 80% at p = 0.05). Behavior-specific evaluations—particularly perceived feasibility (β = 0.355), descriptive norms (β = 0.267), and cost-benefit evaluations (β = 0.235)—can explain most of the variance (44% with a total R² = 61%). Furthermore, trust in specific sources (β = 0.106), general trust (β = 0.098), and negative attitudes toward nature (β = 0.077) are positively related to adaptation, particularly regarding public behaviors (supporting community projects and policies). However, evaluations directly related to CC, such as risk perception (β = 0.010) or how much a behavior helps prevent damage (adaptation efficacy, β = −0.042)), do not explain adaptation, except for an effect of adaptation efficacy on changing daily behaviors. Experiences with and expectations of CC consequences are mostly unrelated to adaptation. However, worries about such events are correlated with adaptation (r between 0.097 and 0.360). We conclude that, to promote adaptation behaviors in this region, the focus should be on the characteristics of the behavior performance (e.g., its costs or feasibility), not on the expected risks of extreme events because of CC.

People with disabilities experience inequitable exposure to social determinants of health (SDOH) that contribute to disparate health outcomes, including psychological distress. There is little research examining which SDOH have the strongest effect on psychological distress among people with disabilities. This leaves healthcare providers and policy makers with insufficient information to make well-informed treatment decisions or allocate resources effectively. We explored the association between SDOH and disability and which factors may moderate the association between disability and psychological distress. Using data from the US Census Bureau’s Household Pulse Survey (Phase 3.5), we examined SDOH among people with and without disability (n = 26,354). Among people with disability, the odds of severe psychological distress were highest among those who had low incomes (OR = 4.41, 95% CI: 3.51–5.60), were food insecure (OR = 3.75, 95% CI: 3.43–4.10), housing insecure (OR = 3.17, 95% CI: 2.82–3.58), or were unable to work (OR = 1.98, 95% CI: 1.80–2.18). Only difficulty paying for household expenses moderated the association between disability and severe psychological distress (OR = 9.81, 95% CI: 7.11–13.64). These findings suggest that supporting employment and economic opportunities and improving access to safe and affordable housing and food may improve psychological well-being among people with disabilities.

The urgency of mitigating climate change and the challenges it poses to ecosystems and human systems are highlighted in the Intergovernmental Panel on Climate Change’s (IPCC) Sixth Assessment Report (AR6). In order to achieve sustainable development, it is imperative to adopt a series of adaptive measures to enhance the resilience of various sectors to climate change and reduce greenhouse gas emissions. This article analyzes the driving mechanism behind the reduction in electricity consumption by urban residents based on 302 valid questionnaires from 18 communities in nine districts in B City. Using a method that combines qualitative and empirical research, the study proposes policy recommendations aimed at guiding urban residents toward reducing their electricity consumption. These recommendations serve as a policy reference for cities striving to achieve sustainability and low-carbon targets. The primary innovations and conclusions of the study are as follows: (1) this study summarizes the primary factors and processes influencing the reduction in electricity consumption among urban residents, examined from the following three perspectives: residents’ characteristics, psychological understanding, and external environment. (2) On the basis of the research data, empirical analysis and hypothesis testing are conducted using a variety of mathematical and statistical methods. The results indicate significant differences in the electricity consumption reduction behavior of heterogeneous urban residents in both public and private areas. Subjective norms, perceived behavioral control, and knowledge of electricity conservation have significant direct influences on residents’ willingness to reduce their electricity consumption. Among these factors, subjective norms have the most significant impact, while the impact of attitude is negligible. Economic incentive policies have a significant positive regulatory effect on the relationship between “willingness (intention)” and “private area electricity consumption reduction behavior”.

Social representations of the war, anchored in historical experience and cultural values, play a motivational role in justifying collective behavior. Following Russia’s 2022 invasion of Ukraine, the research delves into the meanings associated with war through a social representation approach. Employing Doise’s sociodynamic approach, researchers identify the semantic field linked with war and analyze its organizing principles, revealing the variability of representations. In total, 313 Italian participants (female = 241, 75.4%; age range = 18–74) completed a questionnaire featuring a free association task with the word “war”, providing demographic and political and religious orientation data. Lexical correspondence analysis, utilizing Spad-t software, highlights three polarized themes: the emotional dimension aroused by war, media-conveyed imagery, and the underlying causes of conflict. The social anchoring analysis projects variables such as gender and political orientation onto a factorial plane. Finally, cluster analysis dissects psychological anchoring, identifying four distinct groups characterized by their descriptions of war: effects, reasons, emotions, and images. Theoretical and practical implications are discussed. Full article

Global climate change presents a serious threat to the sustainable development of human society, highlighting the urgent need to develop effective adaptation strategies to mitigate the impact of climate-related disasters. Campus waterfront green spaces, integral to the blue-green infrastructure, have been demonstrated to facilitate stress recovery. However, in hot and humid regions, severe outdoor thermal conditions may impair students’ mental and physical health and cognitive function, leading to symptoms such as increased stress, anxiety, and depression. This study examined the influence of outdoor thermal environments on health recovery by selecting three different waterfront green spaces in this climate: Space A (medium water body, sky view factor (SVF) = 0.228), Space B (large water body, SVF = 0.808), and Space C (small water body, SVF = 0.292). The volunteers’ thermal comfort and the restorative benefits of these spaces were evaluated via the perceived restorativeness scale (PRS), heart rate (HR), and electrodermal activity (EDA). We found variations in the neutral physiological equivalent temperature (PET) across the spaces, with values of 28.1 °C (A), 28.9 °C (B), and 29.1 °C (C). The lowest skin conductance recovery rate (R_SC) at 0.8811 was observed in Space B, suggesting suboptimal physiological recovery, despite higher scores in psychological recovery (fascination) at 15.23. The level of thermal comfort in this hot and humid region showed a negative correlation with the overall PRS score, the “being away” dimension, and heart rate recovery (R_HR). At a lightly warm stress level, where PET increased from 31.0 to 35.7 °C, R_SC peaked between 1.45 and 1.53 across all spaces. These insights provide guidance for urban designers and planners in creating waterfront green space designs that can improve the urban microclimate and promote thermal health, achieving sustainable health.

In-vehicle information system (IVIS) use while driving has raised concerns about driver distraction, especially for young drivers. To understand better their psychological factors, an extended theory of planned behavior (TPB) was employed to predict young drivers’ IVIS use intentions and behavior while driving. A two-wave longitudinal survey was conducted to explore the temporal effects of ‘intention–behavior’ causality. At Time 1, 236 qualified participants completed a main questionnaire assessing the standard TPB constructs (attitude, subjective norms, and perceived behavior control) and the extended constructs (descriptive norms, moral norms, and perceived risks). At Time 2, 145 follow-up questionnaires measuring self-reported behavior were successfully administered. The hierarchical multiple regression analyses showed that the standard constructs account for 36.5% of the intention variance and 41.2% of the behavior variance. The extended constructs additionally contributed 20.3% of intention variance. All variables were identified as significant predictors of intentions, except for perceived crash risks and perceived risks of being caught and fined. The sole significant predictor of prospective behavior was intention. Theoretically, the findings further support the efficacy of the TPB in explaining IVIS use while driving. Practically, it is helpful to design non-legal interventions that sustainably reduce young drivers’ engagement in IVIS-related distractions. Full article

Inflammatory acne vulgaris (IAV) is a common skin condition characterized by the presence of reddish, inflamed, and painful lesions on the skin. IAV can drastically affect individuals, specifically their self-esteem, psychological health, and quality of their life in general. Despite new advances in the field, traditional treatment modalities withstand many challenges. Hence, in the current study, we sought to assess the efficacy and safety of a new pulsed wave mode of the fractional microneedling radiofrequency device in the treatment of IAV. This advanced technique employs insulated microneedles to administer energy to the deep dermis without causing damage to the epidermis. Eighty patients (40 males, 40 females, age 21 ± 3, Fitzpatrick skin type III and IV), with acne severity ranging from moderate to severe, were employed in this trial. They were randomly assigned into two groups, 40 patients each. The treated group (A) underwent four sessions of fractionated microneedle RF, 1.5-month apart, whereas group B was designated as the control group that received placebo treatment. Six months following the last session, the degree of improvement assessed by the quantity of IAV lesions and the overall skin appearance in terms of facial pores, sebum excretion, scar, skin tone, and texture. The RF-treated group showed significant improvement compared to the control group after the follow-up period (p-value = 0.0071). Regarding safety, very mild adverse effects were reported, such as discomfort during the session, pinpoint hemorrhage, and erythema, with no major side effects such as burns, scarring, hyperpigmentation, or hypopigmentation were reported. Thus, our data suggest a potential role of the fractional microneedling radiofrequency device in IAV treatment that is both effective and safe. Full article

Despite an increase in the promotion of equal opportunities at work, there is still persistent discrimination against lesbian and gay (LG) workers. In this vein, this study aimed to systematically review the research investigating the peculiarities of the work experience of LG people, particularly considering the theoretical frameworks in the approach to sexual minorities’ work-related issues, as well as individual and contextual variables influencing the work experience and the impact they may have on health and well-being. We explored the PsycArticles, EMBASE, Scopus, and Web of Science electronic databases and the EBSCOHost (PsycInfo, Psychology and Behavioral Sciences Collection) scholarly search engine, between 01/01/2013 to 01/03/2023, with regards to the search terms “lgb*”, “gay*”, “lesbian*”, “homosexual*”, and “sexual minorit*”, associated with “employee*”, ”personnel”, “worker*”, and “staff”, and with “workplace”, “work”, “job”, “occupation”, “employment”, and “career”. Data were narratively synthesized and critically discussed. Of the 1584 potentially eligible articles, 140 papers contributed to this systematic review. Five main theoretical frameworks were identified: (a) minority stress, (b) sexual prejudice and stigma, (c) queer and Foucauldian paradigms, (d) social identity theories, and (e) intersectionality. Furthermore, significant individual (e.g., outness, disclosure, and work–family conflict) and contextual (e.g., heterosexist and heteronormative workplace climate and culture) variables influencing LG people’s work experience were identified. This review highlights the need to develop a unified theoretical model for the construction of specific measurement tools to assess the work experience of LG people and for the implementation of interventions aimed at minimizing the effects of stigma in work contexts.

Climate change stands out as an especially pressing global concern. The aim of the present study was to explore whether climate change worry decreases during armed conflicts, using two time-points: before and during an armed conflict. Guided by the Transactional Theory of Stress and Coping (TTSC), we examined the interplay between risk appraisal, pro-environmental behaviors (PEBs), and climate change worry. A sample of 202 Israeli adults participated in two waves of data collection, completing self-report measures addressing climate change worry, risk appraisal, and PEBs. Results revealed a significant decline in climate change worry and risk appraisal during the armed conflict, whereas PEBs remained unchanged. Contrary to expectations, the associations between risk appraisal, PEBs, and climate change worry did not weaken during the conflict. Mediation analyses indicated that the decline in risk appraisal led to a decline in PEBs, which subsequently contributed to a decline in climate change worry. However, this mediation effect was partial, with most of the association remaining direct. These findings imply that the psychological impact of armed conflict may temporarily overshadow environmental concerns, emphasizing the need for strategies to maintain environmental awareness and behavior even during an armed conflict.

(1) Background: Our previous studies indicated that low-intensity extremely low-frequency electric field (ELF-EF) treatment alters autonomic activities, as revealed through heart rate variability (HRV) analysis. However, the high-frequency (HF) component of HRV that reflects parasympathetic activity showed no changes either during or after the end of the treatment, suggesting the involvement of sympathetic nerves. (2) Methods: To examine this issue in the present study, the effect of ELF-EF on skin conductance (SC), which is controlled solely by sympathetic nerves, was analyzed. Twelve healthy subjects underwent a 20 min ELF-EF treatment (applied voltage: 9 kV, induced current density: below 6 mA/m²) and a sham treatment in a random order with an interval of more than 2 weeks. SC and HRV were recorded under the eyes-open condition during a 2 min period both before and after the treatment. (3) Results: The number of spontaneous fluctuations in skin conductance (SC-SFs) significantly decreased after the ELF-EF treatment, suggesting psychological changes, including relaxation. The skin conductance level, heart rate, and HRV indices did not change after the ELF-EF treatment. (4) Conclusion: The results support the idea that low-intensity ELF-EF affects autonomic nerves by reducing sympathetic activity, as reflected by SC-SFs. Full article
