Background/Objectives: Childhood obesity remains a major public health issue, particularly in Mediterranean countries such as Greece. Although parental influences on children’s weight have been extensively studied, fewer studies have jointly examined parental mental health, feeding practices, sociodemographic factors, and biological stress markers. This study aimed to investigate associations between psychological status, educational level, feeding behaviors, and children’s Body Mass Index (BMI) in a Greek sample. A pilot assessment of salivary cortisol was included in evaluating its feasibility as an objective biomarker of parental stress. Subjects and Methods: A total of 103 parent–child dyads participated in this cross-sectional study. Children’s BMI was classified using World Health Organization (WHO) growth standards. Parental stress, anxiety, and depressive symptoms were assessed using the Perceived Stress Scale-14 (PSS-14) and the Depression Anxiety Stress Scale-21 (DASS-21) questionnaires. Feeding practices were evaluated with the Comprehensive Feeding Practices Questionnaire (CFPQ). Statistical analyses included Pearson correlations, independent samples t-tests, one-way ANOVA, Mann–Whitney U, and Kruskal–Wallis tests. A subsample provided saliva samples for cortisol analysis to assess feasibility and explore the potential associations with parental stress indicators. Results: Parental BMI showed a strong positive association with child BMI (p = 0.002). Higher parental anxiety (p = 0.002) and depression (p = 0.009) were also associated with increased child BMI. Restrictive (p < 0.001) and emotion-driven (p < 0.001) feeding practices were associated with higher child BMI, whereas monitoring (p = 0.013) and health-promoting feeding practices (p = 0.001) appeared protective. Lower parental education was related to a higher BMI in both parents (p = 0.001) and children (p = 0.002) and to more frequent use of restrictive feeding strategies (p = 0.001). WHO charts identified a greater proportion of children as overweight or obese compared with the Centers for Disease Control and Prevention (CDC) criteria. The analysis showed statistically significant differences between the two classification systems (χ² (4) = 159.704, p < 0.001), indicating that BMI categorization varies considerably depending on the reference system used. No significant associations were observed with residential environment or salivary cortisol, likely due to the limited size of the pilot biomarker subsample. Conclusions: The findings highlight the combined effect of parental mental health status, educational level, and feeding practices on child BMI within the Greek context. The preliminary inclusion of a biological stress marker provides added value to the existing research in this area. These results underscore the importance of prevention strategies that promote parental psychological wellbeing and responsive feeding practices while addressing socioeconomic disparities to reduce the childhood obesity risk.

Background/Objectives: Professional quality of life influences patient care, staff well-being, and organizational efficacy. The COVID-19 pandemic placed pressure on healthcare professionals, disrupting their professional quality of life and imposing a psychological burden. In Greece, these issues were intensified by a decade of economic crisis, marked by constrained healthcare budget, personnel shortages, and insufficient resources. This study investigates the pandemic’s impact on the professional quality of life of Greek healthcare professionals to support targeted interventions. Methods: A cross-sectional study was conducted using descriptive statistics. The participants were a convenience sample of 246 healthcare professionals from a Greek regional university hospital with at least one year of experience and who had worked with COVID-19-positive or potentially exposed but asymptomatic patients. Data were collected between March and June 2021 using the Professional Quality of Life Scale (version 5). Results: Of the 246 participants, 81.3% were women and 33.8% were aged 50 or older. Moderate concern and fear regarding COVID-19 were reported, with 34.6% extremely afraid of transmitting the virus to family or friends and 22.8% to patients or their families. Overall professional quality of life was moderate: compassion satisfaction was moderate to high, while burnout and secondary traumatic stress were moderate to low. Higher compassion satisfaction was linked to holding a position of responsibility. Burnout was associated with having children, permanent employment, years of experience, and increased pandemic-related fear. Higher secondary traumatic stress was associated with older age, more years of experience, and greater pandemic-related fear. Conclusions: These findings support international research and highlight that the moderate levels observed indicate intrinsic motivation based on professionalism in patient care, providing evidence of resilience and coping mechanisms that reduce psychological consequences on well-being due to the pandemic.

Background/Objectives: Von Hippel–Lindau (VHL) disease is a rare autosomal dominant hereditary disorder. Central nervous system hemangioblastomas are one of the most common tumor types associated with VHL disease. Although these tumors are histologically benign, delayed diagnosis and treatment may result in severe neurological dysfunction, permanent disability, and even death. However, little is known about the experiences of patients with VHL disease. The aim of this study was to gain a better understanding of the illness experiences and psychological responses of patients with VHL disease accompanied by central nervous system hemangioblastomas. Methods: A qualitative study based on a semi-structured guide was conducted. Twelve participants were recruited. Data were collected through face-to-face interviews and analyzed using the constant comparative method. Results: Four themes and their subthemes were identified: 1. powerlessness—unpredictable disease progression and uncontrollable continuity; 2. negative emotional experiences—guilt and self-blame, depression, and low self-esteem; 3. compromise—acceptance of fate, positive outlook, and sense of hope; and 4. persistent worry—worries about family members, anxiety regarding finances and employment, and uncertainty regarding the future. Conclusions: This study identified four major themes in the illness experiences of patients with VHL disease accompanied by central nervous system hemangioblastomas, which provided deep insights into the care needs of individuals with VHL disease. Healthcare providers should develop effective measures to enhance patients’ ability to maintain a good quality of life and confront the future with resilience. Full article

This study investigated how illuminance and spectrum in office lighting affect psychological fatigue, preference, visual comfort, and cognitive performance. Forty adults participated in a repeated-measures experiment under four conditions with two illuminance levels (500, 1000 lx) and two LED types (full-spectrum, conventional). For each condition, Karolinska Sleepiness Scale scores (fatigue), Office Lighting Survey ratings (preference, visual comfort), and Alphanumeric Verification Task performance (work speed, accuracy) were collected. Linear mixed-effects modeling was applied alongside correlation and regression analyses to examine condition effects and associations between variables. Compared to 500 lx, ΔKSS significantly decreased under 1000 lx, confirming that increased illuminance is associated with reduced psychological fatigue. At the same illuminance level, full-spectrum LEDs showed benefits, including lower fatigue and faster responses. Preference and visual comfort showed minimal direct sensitivity to lighting conditions but were moderately and positively correlated, while fatigue exhibited significant negative correlations with both preference and response speed. An interaction between illuminance and spectrum on accuracy suggested a speed–accuracy trade-off under high-illuminance full-spectrum lighting. Overall, the findings indicate that office lighting, particularly illuminance and spectral quality, acts as a human-centered factor shaping an interconnected response network linking fatigue, affective appraisal, and task performance.

Background: By exploring the principles of Gestalt psychology, the neural mechanisms of perception, and computational models, scientists aim to unravel the complex processes that enable us to perceive a coherent and organized world. This multidisciplinary approach continues to advance our understanding of how the brain constructs a perceptual world from sensory inputs. Objectives and Methods: This study investigates the nature of visual perception through an experimental paradigm and method based on a comparative analysis of human and artificial intelligence (AI) responses to a series of modified square images. We introduce the concept of a “phenomenal gradient” in human visual perception, where different attributes of an object are organized syntactically and hierarchically in terms of their perceptual salience. Results: Our findings reveal that human visual processing involves complex mechanisms including shape prioritization, causal inference, amodal completion, and the perception of visible invisibles. In contrast, AI responses, while geometrically precise, lack these sophisticated interpretative capabilities. These differences highlight the richness of human visual cognition and the current limitations of model-generated descriptions in capturing causal, completion-based, and context-dependent inferences. The present work introduces the notion of a ‘phenomenal gradient’ as a descriptive framework and provides an initial comparative analysis that motivates testable hypotheses for future behavioral and computational studies, rather than direct claims about improving AI systems. Conclusions: By bridging phenomenology, information theory, and cognitive science, this research challenges existing paradigms and suggests a more integrated approach to studying visual consciousness.

The rapid advancement of artificial intelligence (AI) in e-commerce has intensified data-driven personalization, raising important questions about its psychological implications for consumers and its role in shaping sustainable and responsible digital business practices. This study examines how AI-driven personalization affects consumer psychological well-being in the Turkish e-commerce market and investigates the roles of privacy concerns and brand trust in shaping this relationship from a social sustainability and responsible AI perspective. The research develops and empirically tests an integrated model comprising perceived personalization, privacy concerns, psychological well-being, and brand trust. Survey data from 400 active e-commerce customers were analyzed using partial least squares structural equation modeling (PLS-SEM). Findings show that both perceived relevance and perceived specificity significantly enhance psychological well-being by reducing cognitive overload and increasing perceived value. However, these personalization dimensions also increase privacy concerns, with perceived specificity exerting a notably stronger effect. Privacy concerns negatively affect psychological well-being and competitively mediate the relationship between personalization and well-being, reflecting the Personalization–Privacy Paradox in AI-driven e-commerce contexts. Moreover, brand trust significantly moderates this dynamic by weakening the harmful impact of privacy concerns on psychological well-being. Overall, the findings indicate that privacy concerns represent a latent social cost that can undermine the long-term sustainability of data-intensive business models when not governed by trust-based mechanisms.

Frontline workers across health, emergency, and social care sectors are repeatedly exposed to distressing events and chronic stressors as part of their occupational roles. Unlike single-event trauma, these cumulative exposures accrue over time, generating persistent psychological and physiological strain. Traditional diagnostic frameworks, particularly post-traumatic stress disorder (PTSD), were not designed to capture the layered and ongoing nature of this occupational trauma. This commentary introduces the concept of Persistent Traumatic Stress Exposure (PTSE), a framework that reframes trauma among frontline workers as an exposure arising from organisational and systemic conditions rather than solely an individual disorder. It aims to reorient understanding, responsibility, and intervention from a purely clinical lens toward systems, cultures, and organisational duties of care. PTSE is presented as an integrative paradigm informed by contemporary theory and evidence on trauma, moral injury, organisational stress, and trauma-informed systems. The framework synthesises findings from health, emergency, and social care settings, illustrating how repeated exposure, ethical conflict, and institutional pressures contribute to cumulative psychological harm. PTSE highlights that psychological injury may build across shifts, careers, and lifetimes, requiring preventive, real-time, and sustained responses. The framework emphasises that effective support is dependent on both organisational readiness, the structural conditions that enable trauma-informed work, and organisational preparedness, the practical capability to enact safe, predictable, and stigma-free responses to trauma exposure. PTSE challenges prevailing stigma by framing trauma as a predictable occupational hazard rather than a personal weakness. It aligns with modern occupational health perspectives by advocating for systems that strengthen psychological safety, leadership capability and access to support. By adopting PTSE, organisations can shift from reactive treatment models toward proactive cultural and structural protection, honouring the lived realities of frontline workers and promoting long-term wellbeing and resilience.

From an interbehavioral and contingential perspective, family dialogues about sexuality are understood as patterns of verbal interaction regulated by social, gender, and caregiving contingencies rather than as individual attitudes or intentions. Background: This study analyzes the functional conditions under which family dialogues about sexuality occur between mothers and their adolescent sons and daughters, considering caregiving roles and gender norms that regulate these interactions. The research aimed to identify the functional relations between communicative practices and the social contingencies that maintain or inhibit them. Methods: A qualitative approach grounded in interbehavioral psychology was employed, using semistructured interviews with 40 mothers of students from a public middle school in Puebla, Mexico. Data were analyzed through contingency analysis, distinguishing micro- and macrocontingential systems related to family sexual education. Results: Results show that, although patterns of avoidance and discourse displacement toward schools or peers persist, families exhibit increasing openness toward comprehensive sexuality education and recognize its preventive value against violence, adolescent pregnancy, and misinformation. Functional delegation and adolescent mediation of dialogue were identified, along with emerging inclusive macrocontingencies linked to the acceptance of diverse families and LGBTIQ+ themes. Conclusions: It is concluded that households function as self-regulated interbehavioral systems in which historical and gender contingencies restrict sexual dialogue, yet gradual functional changes toward respect, inclusion, and shared educational responsibility are observed.

Women with intellectual disabilities (IDs) face persistent health inequities, particularly in preventive services such as breast cancer screening, where participation rates remain disproportionately low. These disparities contribute to higher mortality and poorer survivorship outcomes, often linked to later-stage diagnoses. To better understand these challenges and inform the development of inclusive screening programs, this qualitative study conducted in Austria explored barriers, facilitators, and needs related to breast cancer screening from the dual perspectives of 17 women with mild-to-moderate IDs aged 45 and older and 10 caregivers. Semi-structured focus groups and interviews were analyzed thematically within a constructivist framework, integrating perspectives from both groups. Barriers included social taboos around sexuality, psychological distress, exclusion through standardized procedures, and unclear responsibility among stakeholders. Facilitators involved person-centered communication, accessible information, emotional and practical support, and familiar healthcare environments. Women with IDs expressed a strong desire for education, autonomy, and inclusion, while caregivers played a pivotal role in enabling access. These findings demonstrate that low screening participation among women with IDs is driven by systemic and organizational barriers rather than lack of health awareness or willingness to participate. Without structurally inclusive design, organized screening programs risk perpetuating preventable inequities in early detection. Embedding accessibility, clear accountability, and person-centered communication as standard features of breast cancer screening is therefore a public health priority to reduce avoidable late-stage diagnoses and narrow survival disparities for women with IDs.

Understanding how investors maintain positions during adverse market conditions, investment grip, is increasingly important as retail participation rises and information environments diversify. While prior research identifies demographic, psychological, and economic determinants of investment grip, little is known about how information sources influence investors’ tolerance for losses. This study examines the relationship between investment information channels and investment grip among Japanese retail investors using a large-scale dataset of 161,677 respondents from the 2025 Survey on Life and Money. Investment grip is measured through a hypothetical loss scenario, and ordered probit and probit models are used to analyze associations between loss tolerance, information sources, and investor characteristics. Results show that reliance on professional information sources such as outsourced independent financial advisors, one’s own securities company, other securities firms, and external financial experts is negatively associated with investment grip. Free information sources, including mass media and personal networks, are also linked to lower loss tolerance. In contrast, reliance on social media is consistently associated with higher investment grip. Financial literacy, wealth, and age increase investment grip, whereas risk aversion, short-term outlooks, and family responsibilities reduce it. These results have implications for policy design, advisory practices, and digital and AI-enhanced investment platforms. Full article

Objective: To analyse written submissions from individuals and families with lived experience of attention-deficit hyperactivity disorder (ADHD) to the 2023 Australian Senate Inquiry, using artificial intelligence (AI)-assisted thematic analysis. The aim was to identify priority concerns, service needs, and community-proposed solutions. Methods: A mixed-methods study of 505 publicly available submissions from individuals with ADHD and their families. Submissions were analysed using large language model (LLM)-assisted data extraction and thematic clustering, with human validation and review. Main Outcome Measures: Frequency and thematic distribution of (1) problems experienced; (2) services wanted; and (3) solutions suggested. Results: Thematic analysis of 480 eligible submissions revealed high costs and long wait times for assessment and treatment (each cited by 46%), lack of specialised care (39%), diagnostic delays (36%), and gender bias (27%). The most common service request was for affordable and accessible ADHD-specific care (71%), followed by services tailored to diverse populations and life stages. Proposed solutions focused on Medicare-funded access to psychological and psychiatric services (68%), expanded roles for general practitioners, improved provider training (39%), and recognition of ADHD under the National Disability Insurance Scheme. Submissions also highlighted misalignment between current clinical guidelines and public expectations. Conclusions: The findings highlight substantial unmet needs and systemic barriers in ADHD diagnosis and care in Australia. The AI-assisted analysis of consumer submissions offers a scalable method for integrating lived experience into policy development, providing numerical weighting to the individuals’ responses. Coordinated reforms in access, funding, and workforce training are needed to align services with both clinical evidence and community expectations. Full article

Because LLMs are still in development, what is true today may be false tomorrow. We therefore need general strategies for debiasing LLMs that will outlive current models. Strategies developed for debiasing human decision making offer one promising approach as they incorporate an LLM-style prompt intervention designed to access additional latent knowledge during decision making. LLMs trained on vast amounts of information contain information about potential biases, counter-arguments, and contradictory evidence, but that information may only be brought to bear if appropriately prompted. Metacognitive prompts developed in the human decision making literature are designed to achieve this and, as I demonstrate here, they show promise with LLMs. The prompt I focus on is “could you be wrong?” Following an LLM response, this prompt leads LLMs to produce additional information, including why they answered as they did, identifying errors, biases, contradictory evidence, and alternatives, none of which were present in their initial response. Further, this metaknowledge often reveals that how LLMs and users interpret prompts are not aligned. I demonstrate this prompt in three cases. In the first two cases I use a set of questions taken from recent articles identifying LLM biases, including implicit discriminatory biases and failures of metacognition. “Could you be wrong” prompts the LLM to identify its own biases and produce cogent metacognitive reflection. In the last case I present an example involving convincing but incomplete information about scientific research (the too much choice effect), which is readily corrected by “could you be wrong?” In sum, this work argues that human psychology offers a valuable avenue for prompt engineering, leveraging a long history of effective prompt-based improvements to decision making.

Background: Ghosting, the sudden cessation of communication without explanation, is a growing phenomenon in digital interactions. Objective: This study translated and validated the Ghosting Questionnaire (GHOST) into French to address the lack of a culturally appropriate tool for French-speaking populations. Methods: Using a cross-sectional design, we followed rigorous translation protocols, including forward and back translation, expert review, and pilot testing. A diverse group of 274 French-speaking adults participated in a multisite study in Bahrain and Tunisia by completing the French language GHOST and the Romantic Ghosting Scale (RG-C). Results: Psychometric analyses revealed strong reliability (Cronbach’s α = 0.880, test–retest ICC = 0.920) and a unidimensional structure (CFI = 0.963, RMSEA = 0.058). Convergent validity was confirmed through significant correlations with RG-C subscales: Role of Aggressor (r = 0.899), Role of Victim (r = 0.829), and Emotional Impact (r = 0.632, all p < 0.001). Item response theory analysis demonstrated proper category functioning and meaningful item hierarchy across ghosting severity levels. Conclusions: The French GHOST offers a robust instrument for researchers and clinicians to explore ghosting’s psychological impacts in French-speaking communities. Full article

Background/Objectives: Falls are a major global issue for older adults, and emotional stress may increase the risk due to its effects on postural control and balance. However, the immediate effects of a stressful stimulus on objective measures of balance and fall risk are unknown. The study aims to explore differences in older adults’ performance on the Timed Up and Go (TUG) test before and after such exposure. Methods: In this cross-sectional study, 31 older adults (71.6 ± 4.98 years) were exposed to an emotionally stressful stimulus using high-arousal images from the International Affective Picture System. Participants performed the TUG before (t1) and after (t2) exposure as the primary outcome measure. To assess the physiological and psychological impact of the stressful stimulus, heart rate variability (HRV) was recorded before and during image viewing. A visual analogue scale (VAS) of unease was completed both before and after the stimulus. Results: During the stressful stimulus, the HRV high-frequency (HF) band decreased significantly (p = 0.001), while the low-frequency (LF) band (p = 0.002) and the LF/HF ratio (p = 0.004) showed a significant increase. Similarly, after stressful stimulus, VAS scores demonstrated a statistically significant increase (p < 0.001). The time to complete the TUG showed a statistically significant increase at t2 (p < 0.001). Conclusions: The stressful stimulus triggered both physiological and subjective stress responses. Subsequently, TUG test performance declined (increased duration), suggesting that emotionally stressful stimuli could deteriorate functional balance performance in older adults, potentially increasing fall risk.

Pancreatic ductal adenocarcinoma (PDAC) is highly lethal, and many patients cannot undergo curative surgery due to frailty. Multimodal prehabilitation: combining exercise, nutrition, and psychological support improves functional readiness, but its biological impact on the PDAC tumor microenvironment (TME) is unclear. In this exploratory pilot study, we profiled resected PDAC tissues from prehabilitation-treated patients and matched controls using NanoString GeoMx Digital Spatial Profiling across immune, tumor, and stromal compartments (n = 4). Transcriptomic signatures were analyzed via differential expression, pathway enrichment, and MCP-counter deconvolution; protein-level validation used multiplex immunofluorescence (n = 8). Ligand–receptor modeling assessed cell–cell communication, and prognostic relevance was evaluated in TCGA-PDAC (n = 178). Prehabilitation was associated with increased NK-cell cytotoxicity, interferon response, and chemokine recruitment, as well as higher neutrophil signatures (p < 0.01) and reduced fibroblast signatures (p < 0.05). Tumor regions showed lower MAPK and PI3K/AKT activity, while stroma exhibited decreased TGF-β and Wnt signaling. Immunofluorescence confirmed neutrophil infiltration and reduced fibroblast density. TCGA analysis linked neutrophil-high/fibroblast-low profiles to longer survival (1044.6 vs. 458.7 days, p = 0.0052). These findings suggest prehabilitation may promote a more immune-active, less fibrotic TME in PDAC, resembling transcriptional states associated with improved survival. Prospective studies integrating biological and clinical endpoints are warranted. Full article
