This study introduces the Skeptical Optimism Scale (SkO) and presents preliminary evidence of its content, construct, and criterion validity. Skeptical optimism refers to dispositional tendencies of having general positive expectations about the future, conditional on critical analysis and in-depth exploration of (potential negative) outcomes. We developed an initial pool of 31 items that explore positive expectations in three main life domains (finding solutions to difficult problems, mastering novel and challenging tasks, and effectively dealing with general life challenges) that were subject to content analysis by eight independent raters. The remaining items were tested for criterion and predictive validity in two samples (N = 198 and N = 417 participants). Factor analyses supported a three-factor structure and the refined 17-item version of the scale showed good reliability and validity. To support applications in settings requiring brief instruments, we also developed a 9-item version, preserving the factorial structure and psychometric qualities of the original scale. The results show that the 17 as well as 9-item SkO scales have a good criterion validity as they positively and significantly correlate with the core self-evaluation scale, critical thinking disposition, and grit. Moreover, our results show that the SkO has good predictive validity as it is the only significant predictor of the creativity quotient in our sample. Full article

Background: Deep surgical site infections (SSIs) represent a serious complication following abdominal trauma surgery; however, comprehensive risk factor analysis in large trauma populations remains limited. Although surgical site infections are recognized as preventable complications, little is known about the specific risk factors and clinical outcomes associated with deep SSIs in trauma patients at the national level. Methods: A retrospective cohort study analyzed data from the National Trauma Data Bank from 2020–2022, including 1,198,262 trauma patients with complete demographic, injury severity, and surgical procedure data. Deep SSI development, length of hospital stay, intensive care unit utilization, duration of mechanical ventilation, discharge disposition, and in-hospital mortality were assessed. Multivariate logistic regression was used to identify independent risk factors and quantify associations between patient characteristics and deep SSI occurrence. Results: Deep SSIs occurred in 601 patients (0.05%). Affected patients were younger (median 41 vs. 54 years, p < 0.001), predominantly male (73.7% vs. 61.8%, p < 0.001), and exhibited higher injury severity scores (median 17.0 vs. 5.0, p < 0.001). Major abdominal surgery was the strongest independent predictor (OR 3.08, 95% CI: 2.21–4.23, p < 0.001), followed by injury severity score (OR 1.05, 95% CI: 1.04–1.06, p < 0.001) and ICU length of stay (OR 1.04 per day, 95% CI: 1.03–1.05, p < 0.001). Patients with deep SSIs demonstrated dramatically increased hospital stays (89.5% vs. 4.5% exceeding 21 days, p < 0.001), reduced home discharge rates (28.5% vs. 48.9%, p < 0.001), and higher mortality (4.2% vs. 1.2%, p < 0.001). Conclusions: Major abdominal surgery and injury severity are primary risk factors for deep SSIs in trauma patients, with profound impacts on clinical outcomes and healthcare resource utilization. These findings highlight the importance of targeted prevention strategies for high-risk trauma patients undergoing major abdominal procedures and emphasize the significant burden that deep SSIs place on healthcare systems.

The present study aimed to adapt and validate the Adult Hope Scale (AHS) for the Romanian population, addressing a gap in culturally appropriate instruments for measuring dispositional hope. Based on Snyder’s theoretical model, the AHS was translated, culturally adapted, and administered to 663 Romanian adults. Psychometric evaluation included internal consistency (Cronbach’s α = 0.84 for the eight positively worded items), test–retest reliability (ICC = 0.39 for the full scale), exploratory and confirmatory factor analyses, and assessments of convergent and discriminant validity. The two-factor model of the scale (agency and pathways) was confirmed, with significant item loadings and a strong correlation between the two latent factors (r = 0.717). Convergent validity was supported by moderate correlations with the Brief Resilience Scale (r = 0.36–0.45), while discriminant validity was indicated by low correlations with the Trait Anxiety Inventory (r = 0.18–0.20). Demographic analyses revealed higher hope levels in women and engineers, with significant differences by gender (p = 0.00018), education (p = 0.031), and profession (p = 0.008). Despite moderate temporal stability and one weakly performing item, the Romanian AHS demonstrates strong psychometric properties, making it a valid and reliable tool for assessing hope in research and clinical settings.

This study is titled “Success Factors in Transport Interventions: A Mixed-Method Systematic Review (1990–2022)”. The purpose of the systematic review is to (1) identify effective interventions for transitioning individuals from private car reliance to sustainable transport, (2) summarise psychosocial theories shaping transportation choices and identify enablers and barriers influencing sustainable mode adoption, and (3) determine the success factors for interventions promoting sustainable transport choices. The last search was conducted on 18 November 2022. Five databases (Scopus, Web of Science, MEDLINE, APA PsycInfo, and ProQuest) were searched using customised Boolean search strings. The identified papers were included or excluded based on the following criteria: (a) reported a modal shift from car users or cars to less CO₂-emitting modes of transport, (b) covered the adoption of low-carbon transport alternatives, (c) comprised interventions to promote sustainable transport, (d) assessed or measured the effectiveness of interventions, or (e) proposed behavioural models related to mode choice and/or psychosocial barriers or drivers for car/no-car use. The identified papers eligible for inclusion were critically appraised using Sirriyeh’s Quality Assessment Tool for Studies with Diverse Designs. Inter-rater reliability was assessed using Cohen’s Kappa to evaluate the risk of bias throughout the review process, and low-quality studies identified by the quality assessment were excluded to prevent sample bias. Qualitative data were extracted in a contextually relevant manner, preserving context and meaning to avoid the author’s bias of misinterpretation. Data were extracted using a form derived from the Joanna Briggs Institute. Data transformation and synthesis followed the recommendations of the Joanna Briggs Institution for mixed-method systematic reviews using a convergent integrated approach. Of the 7999 studies, 4 qualitative, 2 mixed-method, and 30 quantitative studies successfully passed all three screening cycles and were included in the review. Many of these studies focused on modelling individuals’ mode choice decisions from a psychological perspective. In contrast, case studies explored various transport interventions to enhance sustainability in densely populated areas. Nevertheless, the current systematic reviews do not show how individuals’ inner dispositions, such as acceptance, intention, or attitude, have evolved from before to after the implementation of schemes. Of the 11 integrated findings, 9 concerned enablers and barriers to an individual’s sustainable mode choice behaviour. In addition, two integrated findings emerged based on the effectiveness of the interventions. Although numerous interventions target public acceptance of sustainable transport, this systematic review reveals a critical knowledge gap regarding their longitudinal impact on individuals and effectiveness in influencing behavioural change. However, the study may be affected by language bias as it only included peer-reviewed articles published in English. Due to methodological heterogeneity across the studies, a meta-analysis was not feasible. Further high-quality research is needed to strengthen the evidence. This systematic review is self-funded and has been registered on the International Platform of Registered Systematic Review and Meta-analysis Protocols (INPLASY; Registration Number INPLASY202420011).

Background and Objectives: Evidence regarding how dispositional traits, antenatal anxiety, substance use, and obstetric events converge to shape post-partum depression (PPD) in South-East Europe is limited. We analysed 102 third-trimester women and followed them to six weeks post-partum, and 102 age-matched community controls were used to (i) compare baseline psychological profiles, (ii) chart antenatal-to-post-partum symptom trajectories, and (iii) build an integrated model of clinically relevant PPD (Edinburgh Post-natal Depression Scale, EPDS ≥ 12). Materials and Methods: All 96 raw variables were forward–backward translated from Romanian, reconciled, and harmonized. The principal instruments used were EPDS, State–Trait Anxiety Inventory form Y (STAI-Y), Revised Obsessive–Compulsive Inventory (OCI-R), NEO Five-Factor Inventory (NEO-FFI-60), and the four-item Maternal Worry and Satisfaction Scale (MWSS). Results: Groups were age-matched (31.1 ± 5.4 vs. 30.3 ± 5.1 years, p = 0.268) but differed in urban residence (39% vs. 17%, p = 0.001) and current substance use (smoking 21% vs. 34%, p = 0.041; alcohol 6% vs. 22%, p = 0.002). Of five personality domains, only openness scored lower in peripartum women (26.1 ± 4.6 vs. 29.3 ± 5.2, p < 0.001). State anxiety rose significantly from pregnancy to puerperium (+5.1 ± 8.4 points, p < 0.001). Post-partum EPDS correlated most strongly with state anxiety (r = 0.62) and neuroticism (r = 0.50). A final model (pseudo-R² = 0.30) identified post-partum state anxiety (OR 1.10 per point, 95% CI 1.05–1.15, p < 0.001) as the independent predictor; neuroticism showed a trend (OR 1.08, p = 0.081). Obstetric factors (prematurity, birth weight, caesarean section) were not significant. Conclusions: In this Romanian cohort, heightened state anxiety—in synergy with high neuroticism and lower openness—dominated the risk landscape of early onset PPD, whereas delivery mode and neonatal status were neutral. Routine perinatal mental health screening should therefore incorporate anxiety metrics alongside depression scales and brief trait inventories to refine preventive targeting. Full article

Background: Glucuronide recycling in the gut and liver profoundly affects the systemic and/or local exposure of drugs and their glucuronide metabolites, impacting both clinical efficacy and toxicity. This recycling also alters drug exposure in the colon, making it critical to establish local concentration for drugs targeting colon (e.g., drugs for colon cancer and inflammatory bowel disease). Methods: In this study, a parent–metabolite middle-out physiologically based pharmacokinetic (PBPK) model was built for genistein and its glucuronide metabolite to estimate the systemic and local exposure of the glucuronide and its corresponding aglycone in rats by incorporating UDP-glucuronosyltransferase (UGT)-mediated metabolism and transporter-dependent glucuronide disposition in the liver and intestine, as well as gut microbial-mediated deglucuronidation that enables the recycling of the parent compound. Results: This parent–metabolite middle-out rat PBPK model utilized in vitro-to-in vivo extrapolated (IVIVE) metabolic and transporter clearance values based on in vitro kinetic parameters from surrogate species, the rat tissue abundance of relevant proteins, and saturable Michaelis–Menten mechanisms. Inter-system extrapolation factors (ISEFs) were used to account for transporter protein abundance differences between in vitro systems and tissues and between rats and surrogate species. Model performance was evaluated at multiple dose levels for genistein and its glucuronide. Model sensitivity analyses demonstrated the impact of key parameters on the plasma concentrations and local exposure of genistein and its glucuronide. Our model was applied to simulate the quantitative impact of glucuronide recycling on the pharmacokinetic profiles in both plasma and colonocytes. Conclusions: Our study underlines the importance of glucuronide recycling in determining local drug concentrations in the intestine and provides a preliminary modeling tool to assess the influence of transporter-mediated drug–drug interactions on glucuronide recycling and local drug exposure, which are often misrepresented by systemic plasma concentrations.

There is growing evidence relating to the risk of cancer in people with obesity. Obesity is already established as one of the strongest predisposing factors to cancer, and ‘obesity-related’ cancers have been defined in previous studies. In this review article, we examine the epidemiological relationship and describe the potential pathophysiological mechanisms that underpin the association between obesity and cancer. These include hormonal and growth factors that are in abundance in persons living with obesity and thereby increase cancer risk. Additionally, the increased disposition towards chronic inflammation in obesity also confers cancer risk. We also examine the impact of obesity on cancer treatment outcomes, focusing on surgery, chemotherapy, and immunotherapy. Conversely, we underline the impact of weight loss on cancer risk by examining different weight loss strategies. Full article

Addressing climate change requires deeper insight into the psychological drivers of pro-environmental behavior. This study investigates how personality traits, climate-related emotions, and demographic factors can predict sustainable consumption and climate action participation using a Bayesian regression approach. Drawing from the HEXACO personality model and key emotional predictors—Climate Change Worry (CCW) and environmental empathy (EE)—we analyzed data from 604 adults in Greece to assess both private and public climate-related behaviors. This research is novel in its integrative approach, combining dispositional traits and affective states within a Bayesian analytical framework to simultaneously predict both sustainable consumption and climate action. Bayesian model testing highlighted education as the most powerful and reliable predictor of sustainable consumption, with increasing levels—namely Doctoral education—linked to more environmentally responsible action. CCW produced small but reliable effects, supporting hypotheses that moderate emotional concern will lead to sustainable behavior when linked to efficacy belief. The majority of HEXACO traits, e.g., Honesty–Humility and Conscientiousness, produced limited predictive power. This indicates in this case that structural and emotional considerations were stronger than dispositional personality traits. For climate action involvement, Bayesian logistic models found no considerable evidence of any predictor, corroborating the perspective that public participation in high effort action is most likely to rely on contextual enablers instead of internal sentiments or attributes. A significant interaction effect between education and gender also indicated that the sustainability effect of education is moderated by sociocultural identity. Methodologically, this research demonstrates the strengths of Bayesian analysis in sustainability science to make sensitive inference and model comparison possible. The results highlight the importance of affect-related structural variables in behavioral models and have applied implications for theory-informed and targeted climate education and communication interventions to enable different populations to act sustainably.

Background: Endometriosis is a chronic, estrogen-dependent inflammatory condition, that not only leads to significant physical symptoms but also exerts a profound psychological and social burden. This study aimed to asjsess the relationship between quality of life (QoL) in women with endometriosis and selected socio-demographic, diagnostic-therapeutic, and psychological factors, emphasizing self-efficacy and dispositional optimism as potential protective resources. Methods: A cross-sectional survey was conducted between 2020 and 2022 in healthcare facilities in eastern Poland. The study included 425 women diagnosed with endometriosis. The research tools were the Endometriosis Health Profile, the General Self-Efficacy Scale, and the Life Orientation Test-Revised, as well as an original socio-demographic and clinical questionnaire. Data were analyzed using descriptive statistics, linear regression, and hierarchical regression to assess the predictive role of psychological resources beyond sociodemographic and clinical variables. Results: A higher number of physicians from various specialties consulted before diagnosis was significantly associated with lower QoL in all EHP-30 domains except infertility (p < 0.05). The perceived economic burden of treatment was significantly related to lower QoL across all domains (p < 0.05). In contrast, higher levels of self-efficacy and dispositional optimism emerged as independent protective factors, positively associated with emotional well-being, social support, sexual functioning, and relationships with medical staff (p < 0.05). Psychological variables accounted for an additional 8.1% of the variance in QoL beyond socio-demographic and clinical predictors. Conclusions: The findings support the relevance of a biopsychosocial framework in managing endometriosis. Psychological resources play a critical role in coping with the disease and should be integrated into personalized care strategies. Full article

Financial literacy plays a crucial role in shaping individual investment decisions by influencing susceptibility to behavioural biases such as heuristics, framing effects, cognitive illusions, and herding mentality. While most existing studies have examined financial literacy as a mediating factor, our study is among the first in the literature to analyse the role of behavioural biases as mediating factors in the relationship between financial literacy and investment decisions. Specifically, we investigate key biases, including overconfidence, herding, disposition effect, self-attribution, anchoring, availability, representativeness, and familiarity. Using purposive sampling, we collected 482 responses through a structured Likert scale questionnaire. The dataset underwent rigorous validation and reliability tests to ensure robustness. We employed Python-based statistical analysis and used Pearson’s correlation and mediation analysis to explore the relationships between financial literacy, behavioural biases, and investment decisions. With the help of these methods, we were able to uncover relationships and causal pathways which further our understanding of the role of behavioural biases in determining the impact of financial literacy on investment behaviour. The findings illustrate a notable positive correlation between investment decisions and financial literacy, implying that people with higher financial literacy levels possess greater and more rational financial decision-making capabilities. Other analyses have revealed that biases have a moderating effect on this relationship, showing another path through which financial literacy impacts behaviour at the level of the investor. By placing behavioural biases as mediating constructs, this research broadens the scope of investor psychology and the body of knowledge in behavioural finance, highlighting the need to change the approach to how financial literacy programs aimed at investors are structured and implemented.

Forgiveness is a multidimensional phenomenon that often functions as a disposition; it is closely linked to psychological well-being and religion/spirituality. However, no validated instruments have been available to assess forgiveness in the Georgian context. This study aimed to adapt the Toussaint Forgiveness Scale (TFS) for use in Georgia and to examine cross-cultural patterns of forgiveness and mental health among Georgian Orthodox Christians and Polish Roman Catholics. Methods: Study 1 (N = 321) validated the Georgian TFS using confirmatory factor analysis and assessed its convergent validity with perceived stress and religiosity. Study 2 applied structural equation modeling to analyze associations between forgiveness dimensions and mental health indicators in Georgian (n = 110) and Polish (n = 111) samples. Results: The Georgian TFS showed good psychometric properties. In both groups, self-forgiveness was associated with lower depressive symptoms; in Georgia, it also predicted higher quality of life. Forgiveness by God predicted reduced anxiety and depression in Georgia but not in Poland. Although path patterns varied, overlapping confidence intervals suggest no significant between-group differences. Conclusions: Forgiveness supports mental health across cultures, especially self-forgiveness. Its expression may show subtle, culturally nuanced patterns, though these require cautious interpretation. Full article

Background: Falls are the leading cause of emergency department (ED) presentations among residential aged care facility (RACF) residents. This study identified the factors influencing the decision to discharge RACF residents from the ED following fall-related presentations. Methods: A single-centred, cross-sectional observational study was conducted in rural Shepparton, Victoria, Australia. The study included residents aged ≥65 in RACFs with fall-related ED presentations between 1 January and 19 November 2024. The main outcome was to determine factors that may prevent unwarranted ED transfers among RACF residents following falls. Statistical methods, including multivariate logistic regression, were used to examine factors associated with ED dispositions. Results: A total of 181 presentations (69.4%) were discharged, and 80 (30.6%) were admitted. The presence of an Advance Care Directive (ACD) (adjusted odds ratio [aOR] = 2.89; 95% confidence interval [CI]: 1.37–6.05) and lower triage levels (aOR = 2.69; 95% CI: 1.06–6.80) increased the odds of discharge. Major injuries (aOR = 0.20; 95% CI: 0.09–0.42) and obvious injuries (aOR = 0.24; 95% CI: 0.10–0.56) reduce discharge chances. Whether computed tomography brain scans were performed or anticoagulation therapy was used did not significantly influence ED discharge chances. Conclusion: In addition to traditional factors associated with ED discharge in post-fall patients from RACFs, an ACD was associated with increased discharge from the ED. Strengthening fall-specific advance care planning, improving ACD accessibility, and enhancing the clinical capacity of RACFs may reduce unnecessary ED transfers and better align care with residents’ goals, particularly in rural settings.

(1) Background: In the era of generative AI (GenAI), assessing AI literacy is essential for understanding how effectively non-expert users can interact with AI. However, existing assessment tools primarily focus on users’ understanding of AI principles or rely on self-reported scales, neglecting critical thinking and actual interaction capabilities. To address this gap, this study aims to design and validate evaluation indicators targeting the behavioral process of human–GenAI interactions and analyze the impact of critical thinking. (2) Methods: Grounded in information literacy and critical thinking frameworks, this study operationalized human–AI interaction capabilities into behavioral indicators and rubrics through observation, surveys, and pilot studies. Data were collected from 121 undergraduates completing two real-world tasks with GenAI, and their interaction processes were documented and evaluated. (3) Results: The indicators showed acceptable inter-rater and internal consistency reliability. Exploratory and Confirmatory Factor Analysis confirmed a three-dimensional structure. Further analysis showed that interaction capabilities varied across gender, academic background, AIGC use frequency, critical thinking disposition levels, and question chain logic. (4) Conclusions: The developed evaluation indicators are reliable and valid. Further analysis reveals that a high critical thinking disposition can offset the disadvantage of lower usage frequency. This highlights the significance of critical thinking in enhancing human–GenAI interaction capabilities. Full article

Previous discussions on customer injustice and emotional labor have primarily focused on employee–customer dyads, often neglecting the role of service co-workers in shaping emotional labor dynamics. To address this gap, the current study integrates intrapersonal and interpersonal factors to explore their joint effects on employees’ emotional labor strategies when encountering customer injustice. A full-factorial experimental design with 2 (self-construal: independent vs. interdependent) × 3 (service co-workers: alone vs. positive attitudes vs. negative attitudes toward customer injustice) is employed, using data from 179 frontline service employees at high-star hotels in Shanghai, with self-construal and service co-workers operationalized as manipulated conditions. Results reveal that self-construal significantly influences surface acting: interdependent individuals are more inclined to engage in surface acting than independent individuals. By contrast, self-construal has no direct effect on deep acting. While service co-workers do not moderate the relationship between self-construal and surface acting, they play a critical role in the relationship between self-construal and deep acting: for interdependent employees, service co-workers’ attitudes (rather than their mere presence) decisively impact deep acting, with positive attitudes promoting deeper emotional engagement and negative attitudes reducing it. This study advances a dual-path framework highlighting how intrapersonal dispositions (self-construal) and interpersonal impression cues (service co-workers’ attitudes) interact to shape emotional labor. By expanding the traditional employee–customer dyad to a triadic model, the study bridges impression management theory and workplace injustice research, offering theoretical insights into how intrapersonal traits and interpersonal dynamics jointly shape contextualized emotional labor. This thereby provides a theoretical foundation for nuanced management strategies in service organizations. Full article

Background: The effectiveness of treatment depends on recognizing the needs and limitations of patients. Hope is a personal resource that facilitates the treatment and recovery process. Dispositional hope encompasses goal-directed action, whereas perceived hope lacks reference to specific content or behavior. This study examined which construct is more strongly related to psychological, physical, and emotional health. Perceived hope requires a new tool for measurement. Adaptation to the Polish cultural context is the second goal of this research. Methods: Data were collected in the international online study Barometer of Hope (n = 1608). Adult participants completed the PSH, ADHS, and a battery of self-report questionnaires assessing several key well-being outcomes. Results: Perceived hope appears to be a more salient construct related to psychological health than dispositional hope, although both aspects of hope demonstrate similar associations with physical health. Confirmatory factor analysis (CFA) supported the hypothesized one-factor structure of the Polish version of the Perceived Hope Scale (PHS-PL), indicating high internal consistency as well as strong convergent and discriminant validity. The PHS-PL showed positive correlations with optimism, life satisfaction, happiness, positive affect, and dispositional hope, and negative correlations with depression/anxiety, loneliness, and negative affect. Additionally, perceived hope was negatively associated with the likelihood of a crisis scenario and positively associated with the likelihood of a flourishing scenario. Conclusions: Our findings confirm that hope is a health-enhancing resource. The PHS is a simple, short, culturally universal method that directly measures hope and can also be successfully used by non-psychologists, such as nurses, physicians, and caregivers. Full article
