Introduction: As global concerns about climate change intensify, emerging research reveals a link between climate change anxiety and individuals' decisions regarding parenthood. More people are choosing not to have children due to worries about their carbon footprint or the future implications of climate change on their offspring. This trend emphasizes the critical necessity for a nuanced comprehension of how environmental concerns intertwine with reproductive intentions. To address this imperative, our study develops the Climate Change-related Reproductive Concerns Scale (CCRCS) and evaluates its psychometric properties. Methods: CCRCS was developed and validated in a sample of 206 Italian adults aged 19 to 51. Ten items were created to evaluate climate change-related reproductive attitudes: 5 anti-reproductive items and 5 pro-reproductive, with their responses reversed for consistency in interpretation. Results: Exploratory factor analysis revealed a single-factor structure, explaining 63.82 % of the variance, with the scale demonstrating good internal consistency (α = 0.85). The factor structure was replicated, and the scale's validity was examined through correlations with measures of eco-paralysis and climate change anxiety, with significant correlations supporting construct validity. Furthermore, the relationship between climate change-related reproductive concerns and adaptation responses was explored, assessing the impact of framing on CCRCS scores. Conclusion: The CCRCS provides a reliable and valid measure of these concerns, highlighting the psychological impact of climate change anxiety on reproductive decision-making and emphasizing the need for nuanced understanding in this area.

While it has been shown that climate change anxiety (emotional distress response to climate change) can enhance pro-environmental behaviours (PEBs) in some subjects, in others it can induce eco-paralysis, thus leading individuals to avoid any form of engagement in actions against climate change. This study aims to clarify which factors influence the relationship between climate change anxiety and the disposition to PEBs, focusing on the role of self-efficacy as a mediating factor. A cross-sectional study was conducted on 394 healthy subjects living in Italy who completed the Pro-Environmental Behaviours Scale (PEBS), the General Self-Efficacy scale (GSE), and the Climate Change Anxiety Scale (CCAS). As a result, the mediation model showed a positive direct effect of the cognitive impairment subscale of CCAS on PEBS and an indirect negative effect of the cognitive impairment subscale of CCAS on PEBS mediated by GSE. These findings show that climate change anxiety has simultaneously two different effects on individuals: it directly encourages PEBs, and indirectly may have detrimental effects on PEBs such as eco-paralysis. Consequently, therapeutic approaches to treat climate change anxiety should not be aimed at rationalising irrational thoughts but rather at helping patients develop coping strategies such as PEBs which, in turn, foster self-efficacy.

Climate change (CC) has a significant impact on human health, resulting in both physical and mental illnesses. Eco-anxiety—the excessive and pervasive fear about the consequences of CC—is the most studied psychoterratic state. This study presents the validation of Italian versions of Hogg’s Eco-Anxiety Scale (HEAS) and the Eco-Paralysis Scale. It also investigates the effects of worry on eco-anxiety and eco-paralysis. The study was conducted on 150 Italian individuals who responded to the two scales and to other questionnaires to make comparisons with the two above. Internal consistency and factorial structure were assessed through Cronbach’s alpha, Confirmatory Factor Analysis and Exploratory Factor Analysis. A median regression was used to assess the association between the EPS and the HEAS and Climate Change Worry Scale (CCWS) and their interaction. HEAS and EPS showed good psychometric properties: HEAS resulted in good internal consistency (Cronbach’s α = 0.986), and the Eco-Paralysis scale had good test-retest reliability (r = 0.988). In both cases, a one-factor structure was suggested to be retained. The interaction terms between HEAS and CCWS (β = −0.02; 95% CI: −0.03, −0.01; p < 0.001) and between HEAS and education (β = −0.05; 95% CI: −0.08, −0.02; p < 0.001) were significant. Therefore, the feeling of worry seems to act as a moderator between climate change anxiety and eco-paralysis since it may appear to influence individuals and their ability to transform anxiety into action. Education plays a role in reducing the risk of Eco-Paralysis in subjects affected by climate change anxiety. Thus, data suggest that working on reinforcing a more cognitive concern might result in more problem-solving-focused strategies to face climate change anxiety and eco-paralysis.

Background Cocaine use disorder (CUD) is a global health issue with no effective treatment. Repetitive Transcranial Magnetic Stimulation (rTMS) is a recently proposed therapy for CUD. Methods We conducted a single-center, randomised, sham-controlled, blinded, parallel-group research with patients randomly allocated to rTMS (15 Hz) or Sham group (1:1) using a computerised block randomisation process. We enrolled 62 of 81 CUD patients in two years. Patients were followed for eight weeks after receiving 15 15 Hz rTMS/sham sessions over the left dorsolateral prefrontal cortex (DLPFC) during the first three weeks of the study. We targeted the DLFPC following the 5 cm method. Cocaine lapses in twice a week urine tests were the primary outcome. The secondary outcomes were craving severity, cocaine use pattern, and psychometric assessments. Findings We randomly allocated patients to either an active rTMS group (32 subjects) or a sham treatment group (30 subjects). Thirteen (42%) and twelve (43.3%) of the subjects in rTMS and sham groups, respectively, completed the full trial regimen, displaying a high dropout rate. Ten/30 (33%) of rTMS-treated patients tested negative for cocaine in urine, in contrast to 4/27 of placebo controls (p = 0.18, odd ratio 2.88, CI 0.9–10). The Kaplan-Meier survival curve did not state a significant change between the treated and sham groups in the time of cocaine urine negativisation (p = 0.20). However, the severity of cocaine-related cues mediated craving (VAS peak) was substantially decreased in the rTMS treated group (p<0.03) after treatment at T1, corresponding to the end of rTMS treatment. Furthermore, in the rTMS and sham groups, self-reported days of cocaine use decreased significantly (p<0.03). Finally, psychometric impulsivity parameters improved in rTMS-treated patients, while depression scales improved in both groups. Conclusions In CUD, rTMS could be a useful tool for lowering cocaine craving and consumption. Trial registration The study number on clinicalTrials.gov is NCT03607591.

Climate change is not only affecting our environment, but also negatively impacting mental health globally. While physical health problems caused by climate change have been increasingly studied in medical literature, few studies have investigated mental health problems caused byclimate change. In order to bridge this gap in the literature and assess the psychological impact of climate change, it is crucial to create adequate psychometric tools such as the Climate Change Anxiety Scale (CCAS) developed by Susan Clayton.In this study, 150 Italian adults (67.4% females, and 32.6% males aged 19–76) were recruited online and required to complete CCAS, as well as GAD-7, K-10, NEP, PEBS, PESE/PSSE, and GSE in order to assess the psychometric properties of and validate CCAS in Italy. Patients were retested after three months. Data was collected from January to June 2021. The study used a 13-item version of the CCAS, which was based on the first two factors of Clayton's original scale. Researchers specifically analyzed internal consistency, test-retest reliability, and discriminant validity.Factor structure of CCAS was specifically addressed: a CFA was carried out to analyze the two-factor structure proposed in the original validation study. An EFA was then conducted and it was hypothesized that a single-factor structure could better fit data.Climate Change Anxiety Scale items exhibited reasonably good internal consistency. Test-retest reliability at a three-month evaluation proved to be good. The experience of climate change anxiety proved to be related to anxiety, pro-environmental behaviors, and low perception of self-efficacy.
