This study examined the psychometric properties of the Family Empowerment Scale (FES) among Latinx parents of children with intellectual and developmental disabilities (IDDs), a population historically underrepresented in empowerment research. Given the cultural and contextual factors that may shape empowerment experiences, Exploratory Structural Equation Modeling (ESEM) was utilized to assess the scale’s structural validity. ESEM supports a four-factor model that aligns with, but also refines, the original structure of the FES. The lack of loading for several items indicates the need for revisions that better reflect the lived experiences of Latinx parents. ESEM provided a more nuanced view of the scale’s dimensional structure, reinforcing the value of culturally informed psychometric evaluation. These results underscore the importance of validating empowerment measures within diverse populations to inform equitable family-centered practices. Full article

Background/Objectives: Decision-making under socially evaluative stress engages a dynamic interplay between cognitive control, emotional appraisal, and motivational systems. Contemporary models of multi-level co-regulation posit that these systems operate in reciprocal modulation, redistributing processing resources to prioritise either rapid socio-emotional alignment or deliberate evaluation depending on situational demands. Methods: Adopting a neurofunctional approach, a novel dual-task protocol combining the MetaCognition–Stress Convergence Paradigm (MSCP) and the Social Stress Test Neuro-Evaluation (SST-NeuroEval), a simulated social–evaluative speech task calibrated across progressive emotional intensities, was implemented. Twenty professionals from an HR consultancy firm participated in the study, with concurrent recording of frontal-temporoparietal electroencephalography (EEG) and bespoke psychometric indices: the MetaStress-Insight Index and the TimeSense Scale. Results: Findings revealed that decision contexts with higher socio-emotional salience elicited faster, emotionally guided choices (mean RT difference emotional vs. cognitive: −220 ms, p = 0.026), accompanied by oscillatory signatures (frontal delta: F(1,19) = 13.30, p = 0.002; gamma: F(3,57) = 14.93, p ≤ 0.001) consistent with intensified socio-emotional integration and contextual reconstruction. Under evaluative stress, oscillatory activity shifted across phases, reflecting the transition from anticipatory regulation to reactive engagement, in line with models of phase-dependent stress adaptation. Across paradigms, convergences emerged between decision orientation, subjective stress, and oscillatory patterns, supporting the view that cognitive–emotional regulation operates as a coordinated, multi-level system. Conclusions: These results underscore the importance of integrating behavioural, experiential, and neural indices to characterise how individuals adaptively regulate decision-making under socially evaluative stress and highlight the potential of dual-paradigm designs for advancing theory and application in cognitive–affective neuroscience.

This paper presents a methodology for determining manufacturing tolerances of feature lines on automotive outer panels using visual sensory tests. Feature lines—narrow and long curved surfaces on automotive panels—play a critical role in the visual appeal of vehicles. However, achieving precise feature lines in mass production is challenging due to material spring-back during the stamping process. Conventional tolerance determination methods are unsuitable for these esthetic elements. To address this, we employed psychophysical sensory tests to find the visual difference thresholds for feature lines. By creating geometric models and conducting controlled sensory tests, we identified the minimum radius variations perceptible to the human eye. Thirty-four participants were tested using the method of constant stimuli, resulting in psychometric functions for feature lines with radii of 8, 10, and 12 mm. The findings suggest manufacturing tolerances of ±1.2 mm, ±1.3 mm, and ±1.5 mm, respectively. This approach provides a quantitative foundation for setting tolerances that balance visual quality with production feasibility. Full article

Objectives: The aim of this study was to evaluate the validity and reliability of the Mindful Eating Behavior Scale (MEBS) by Winkens et al. in Turkish adults. Methods: This cross-sectional validation study was conducted in three stages with 397 participants aged 18–65 years from Istanbul, Türkiye. Stage 1 involved linguistic validation (n = 50), Stage 2 included a psychometric evaluation (n = 397), and Stage 3 a test–retest reliability assessment (n = 50). Internal consistency was assessed using Cronbach’s alpha, and factor structure was examined through exploratory factor analysis (EFA), followed by confirmatory factor analysis (CFA). Results: The Turkish MEBS demonstrated excellent internal consistency (Cronbach’s α = 0.855) and good temporal stability (test–retest r = 0.821). EFA confirmed a four-factor structure explaining 64.01% of the total variance, consistent with the original validation. Factor loadings ranged from 0.50 to 0.85. CFA confirmed acceptable model fit (χ²/df = 3.147, CFI = 0.918, GFI = 0.910, RMSEA = 0.074). The Kaiser–Meyer–Olkin coefficient was 0.85, and Bartlett’s test was significant (χ² = 2960.80, p < 0.05). Conclusions: The Turkish version of the MEBS demonstrates preliminary validity and reliability for assessing mindful eating behaviors in Turkish adults. This validation provides the first culturally adapted mindful eating assessment tool for Turkish clinical practice and research settings. Full article

(1) Background: This study aimed to develop and validate a new instrument to measure relational reflexivity in management settings. Relational reflexivity—defined as the integration of self-awareness, perspective-taking, and interpersonal responsibility—has been discussed conceptually, but it lacks a standardized, psychometrically sound measurement tool. (2) Methods: A 25-item scale was developed based on a literature review and administered to 524 sport management students. Exploratory factor analysis (EFA) was used to identify the underlying structure. A 15-item version, based on item performance and theoretical fit, was then tested using confirmatory factor analysis (CFA) on a randomly selected subsample (n = 400). Model fit was assessed using RMSEA, CFI, TLI, and χ²/df. (3) Results: EFA revealed a five-factor structure consistent with theoretical expectations: self-awareness, perspective-taking, communication and conflict resolution, respect and mediation, and intrapersonal reflexivity, explaining 53.5% of the total variance. CFA confirmed the model with excellent fit indices (RMSEA = 0.0605; CFI = 0.955; TLI = 0.941). Factor loadings were high (0.89–1.13), and all were statistically significant. (4) Conclusions: The result (RRMQ) is a valid and reliable tool for assessing multidimensional relational reflexivity in leadership and team contexts. Its structure reflects both theoretical foundations and psychometric rigor, providing a foundation for future research and practical applications in leadership development. Full article

Depression relapse is a common issue during long-term care. We introduce a privacy-aware explainable personalized federated learning (PFL) framework that incorporates layer-wise relevance propagation and Shapley value analysis to provide patient-specific interpretable predictions from EEG. The study is conducted with the publicly available Healthy Brain Network (HBN) dataset, with analysis conducted for n = 100 subjects with resting-state 128-channel EEG with accompanying psychometric scores, and subject-wise 10-fold cross-validation is used to assess the performance of the model. Multi-channel EEG features and standardized symptom scales are jointly modeled to both increase the clinical context of the model and avoid leakage issues. This results in overall accuracy, precision, recall, and F1-score values of 92%, 91%, 93%, and 90.5%, respectively. The attribution maps from the model suggest region-anchored spectral patterns that are associated with relapse risk, providing clinical interpretability, and the federated setup of the model allows for a privacy-aware training setup that is more easily adaptable to multi-site deployment. Together, these results suggest a scalable and clinically feasible approach to trustworthy relapse monitoring with earlier intervention. Full article

Background: The Gender Variance Scale (GVS) was developed to assess self-perceived masculinity and femininity across diverse gender identities, including binary and non-binary experiences. To date, no validated Italian version was available. Methods: A total of 356 participants (192 transgender and gender-diverse [TGD], 164 cisgender) completed the Italian GVS and the SF-12 Health Survey. Translation and cultural adaptation followed international guidelines. Psychometric evaluation included confirmatory factor analysis (CFA), internal consistency, test–retest reliability (n = 63), convergent validity with health-related quality of life, and group comparisons across gender identity categories. Results: CFA supported the original two-factor model (CFI = 0.916, TLI = 0.905, RMSEA = 0.076, SRMR = 0.053). Internal consistency was high (α = 0.89). The GVS distinguished between gender identity groups: TGD participants scored higher than cisgender peers, and non-binary individuals reported significantly lower scores than both binary groups. Test–retest reliability was strong (r = 0.87–0.99; ICC = 0.992–0.996). Conclusions: The Italian GVS is a valid and reliable measure of gender variance. It provides clinicians, researchers, and educators with a culturally appropriate tool to assess gender expression and support inclusive practices in both community and clinical contexts.

Background/Objectives: Adolescence is a critical developmental phase marked by rapid cognitive, emotional, and social changes that influence how individuals experience psychological energy and exhaustion. Self-Determination Theory recently proposed a dual-process model, based on two distinct, yet related, constructs: Subjective Vitality, associated with well-being and positive health outcomes, and Subjective Depletion, associated with illbeing and negative emotions. Since, to date, no study has investigated vitality and depletion during adolescence, this study aims to validate the Subjective Vitality/Depletion Scale (SVDS) in a large sample of adolescents. Methods: A total of 1111 Italian adolescents (Mage = 14.49, SDage = 1.49; 48% females) completed the SVDS and other validated self-report measures. Specifically, the psychometric properties of the SVDS across biological sex and age groups and latent mean differences across these groups were assessed. Results: Findings supported the dimensionality of the SVDS with two correlated factors, and its construct validity through associations with positive and negative affect and basic psychological needs satisfaction. Full invariance for the SVDS was achieved across biological sex and age groups. Latent mean analyses indicated that males reported higher levels of vitality compared to females (Cohen’s d = 0.46), with no significant differences for depletion; older adolescents reported lower levels of vitality (d = −0.23) and higher levels of depletion (d = 0.20) compared to younger adolescents. Conclusions: These findings support the SVDS as a valid and reliable instrument for assessing energy-related experiences in adolescence. The results suggest meaningful sex differences and a potential developmental trend of declining subjective energy from early to later adolescence. Full article

Within the framework of the 2030 Agenda, universities are key institutions in promoting digital competencies aligned with Sustainable Development Goals (SDGs), particularly SDG 4 (Quality Education) and SDG 10 (Reduced Inequalities). This study evaluates the psychometric properties of the Internet Skills Scale (ISS), adapted for Chilean university students, as a tool to assess how effectively higher education fosters digital skills that enable critical participation and social inclusion. Using a sample of 906 students from nine public universities across Chile, the ISS was linguistically and culturally adapted, and its factorial structure, reliability, validity, and measurement invariance were tested. The results support a four-factor model—operational, navigation, social, and creative skills—under a second-order structure, with strong fit indices (CFI = 0.987; RMSEA = 0.055) and high internal consistency (α > 0.83). The ISS also demonstrated gender-based measurement invariance and convergent validity with digital citizenship. These findings underscore the ISS as a valid instrument for monitoring the effectiveness and equity of digital education policies in universities. Its application contributes to diagnosing institutional performance regarding the integration of digital competencies into curricula, thus guiding improvements in educational strategies toward socially just, inclusive, and sustainable digital participation.

Heart transplantation represents a pivotal intervention for end-stage heart failure, extending survival. However, it imposes profound physical, psychological, and social challenges that often undermine recipients’ quality of life (QoL). These challenges are especially pronounced in collectivist cultural contexts like China, where familial obligations and stigma surrounding chronic illness intensify existential burdens. Grounded in theoretical frameworks including Coping Theory, Self-Determination Theory, Socioemotional Selectivity Theory, and Terror Management Theory, this cross-sectional study explored the interplay between social support and QoL among Chinese heart transplant recipients, elucidating the mediating roles of self-esteem and death anxiety, as well as their sequential chain-mediating pathway. Employing validated psychometric instruments, including the Social Support Rating Scale (SSRS), Rosenberg Self-Esteem Scale (RSES), Templer Death Anxiety Scale (T-DAS) and SF-36 Health Survey, along with chain-mediation modeling, the analysis revealed that social support exerts a direct positive influence on QoL, supplemented by indirect effects through enhanced self-esteem, reduced death anxiety, and a chained cognitive-existential mechanism linking these factors. These insights highlight the complex psychosocial dynamics of post-transplant adaptation, advocating for targeted and culturally attuned interventions. These interventions include family-based support programs, self-esteem enhancement strategies, and death anxiety counseling. The aim is to promote holistic rehabilitation and sustained well-being among heart transplant recipients in China’s context. Full article

Motion perception is a fundamental function of the tactile system, essential for object exploration and manipulation. While human studies have largely focused on discrete or pulsed stimuli with staggered onsets, many natural tactile signals are continuous and rhythmically patterned. Here, we investigate whether phase differences between “simultaneously” presented, “continuous” amplitude-modulated vibrations can induce the perception of motion across fingertips. Participants reliably perceived motion direction at modulation frequencies up to 1 Hz, with discrimination performance systematically dependent on the phase lag between vibrations. Critically, trial-level confidence reports revealed the lowest certainty for anti-phase (180°) conditions, consistent with stimulus ambiguity as predicted by the mathematical framework. I propose two candidate computational mechanisms for tactile motion processing. The first is a conventional cross-correlation computation over the envelopes; the second is a probabilistic model based on the uncertain detection of temporal reference points (e.g., envelope peaks) within threshold-defined windows. This model, despite having only a single parameter (uncertainty width determined by an amplitude discrimination threshold), accounts for both the non-linear shape and asymmetries of observed psychometric functions. These results demonstrate that the human tactile system can extract directional information from distributed phase-coded signals in the absence of spatial displacement, revealing a motion perception mechanism that parallels arthropod systems but potentially arises from distinct perceptual constraints. The findings underscore the feasibility of sparse, phase-coded stimulation as a lightweight and reproducible method for conveying motion cues in wearable, motion-capable haptic devices. Full article

Marital relationship quality significantly influences health outcomes, but validated measurement tools for South Asian populations remain limited. To validate scales measuring trust, commitment, and satisfaction as key components of marital relationship quality among newly married women in Nepal, we conducted a two-wave psychometric validation study in rural Nawalparasi district. The study included 200 newly married women aged 18–25 years, with 192 participants (96% retention) completing 6-month follow-up. We assessed factor structure, internal consistency, test-retest reliability, and criterion validity of trust (eight items), commitment (five items), and satisfaction (seven items) scales using exploratory and confirmatory factor analysis. Exploratory factor analysis identified single-factor solutions for trust and commitment scales and a two-factor model for satisfaction. Confirmatory factor analysis confirmed these structures, with satisfaction comprising marital conflict/dissatisfaction (four items) and general satisfaction (two items) subscales. All scales demonstrated good internal consistency (Cronbach’s α: 0.79–0.96) and significant criterion validity correlations with relationship happiness (r = 0.63–0.72, p < 0.001). Test-retest reliability showed moderate to low stability (r = 0.21–0.51), likely reflecting genuine relationship changes in early marriage. The validated scales provide reliable tools for assessing relationship quality in South Asian contexts, enabling research on marriage-health associations and evidence-based interventions.

Background/Objectives. Quality of nursing care (QNC) is a central concept in healthcare systems worldwide, with growing emphasis on developing reliable and contextually appropriate instruments for its assessment. Over recent decades, there has been a shift from outcome-based evaluation toward more holistic, patient-centered frameworks that consider both clinical indicators and interpersonal dimensions of care. This scoping review aimed to map the range, nature, and characteristics of self-report instruments used to assess the quality of nursing care, including their psychometric properties and contextual applications across different clinical settings. Methods. A systematic search was conducted in CINAHL Complete, MEDLINE (via PubMed), Scopus, Web of Science, and ProQuest Dissertations & Theses, alongside gray literature sources, following the Joanna Briggs Institute (JBI) methodology and PRISMA-ScR guidelines. Studies were included if they reported on the development, validation, adaptation, or application of QNC assessment tools in hospital or community nursing contexts, and were published in English, Portuguese, or Spanish. Results. Fifty-nine studies were included, spanning from 1995 to 2025. The instruments identified were predominantly structured around Donabedian’s structure-process-outcome model, and many emphasized relational domains such as empathy, communication, and respect. Tools like the Good Nursing Care Scale (GNCS), the Quality of Oncology Nursing Care Scale (QONCS), and the Karen Scales demonstrated strong internal consistency (Cronbach’s α ranging from 0.79 to 0.95). Conclusions. Organizational factors, including leadership and staffing, and predictors such as burnout and work intensity, were found to influence perceived care quality. Important gaps remain regarding longitudinal use and integration of patient-reported outcome measures. Full article

Eating Disorders (EDs) are more prevalent among athletes due to performance pressure and body ideals. Emotional regulation is a key factor in ED. This study aimed to (1) examine the reliability and structural validity of the Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CA) in adolescent Mexican athletes, and (2) analyze associations between emotional regulation strategies (expressive suppression and cognitive reappraisal) and ED risk factors (drive for thinness, body dissatisfaction, and bulimia). An instrumental, cross-sectional design was employed with 295 Mexican athletes (Mage = 16.85, SD = 3.27). The ERQ-CA demonstrated good psychometric properties, with acceptable reliability (ω > 0.70) and excellent fit for the two-factor model (CFI = 0.995, RMSEA = 0.018). Emotional suppression was positively associated with all ED risk indicators, whereas cognitive reappraisal was negatively associated. These findings highlight that individual differences in emotion regulation are linked to ED risk in adolescent athletes. Monitoring expressive suppression and promoting cognitive reappraisal may serve as supportive strategies for coaches, parents, and mental health professionals, enhancing emotional flexibility and potentially reducing ED risk.

Background/Objectives: Preceptorship is a key aspect of clinical education for healthcare professions, including nurse practitioners (NP). Numerous studies have explored barriers and facilitators to preceptorship; however, few have used a theory-based, psychometrically sound instrument. The aim of this study was to develop and validate an instrument predicting nurse practitioner preceptorship based on the Integrated Behavioral Model (IBM). Methods: This was an instrument validation study with a longitudinal design. A pool of 82 statements that reflected constructs of the IBM was developed from the existing literature and unpublished studies. Items were evaluated for clarity and construct validity by 20 faculty members and NPs. Further refinement after administration to a small sample of NPs yielded a 60-item Likert-type survey that was sent to NPs in 20 states. A total of 154 NPs repeated the survey after 2–4 weeks to evaluate test–retest reliability. Exploratory and confirmatory factor analysis were used to establish subscales and assess internal consistency, convergent, and discriminant validity. Results: 35 items were retained in the final survey. We identified 10 subscales reflecting constructs in the IBM. All subscales had adequate internal consistency and discriminant validity. One subscale had inadequate convergent validity and test–retest reliability, while another subscale had inadequate content validity. Conclusions: The resultant Predicting Preceptorship Survey is theory-based and psychometrically sound. There is no subscale for one IBM construct, “salience.” This instrument could be used in studies of engagement in preceptorship in order to identify focus areas for interventions to increase the availability of preceptors, and to evaluate the outcomes of those interventions. Future research should include longitudinal studies of preceptorship and validation of the instrument with other professions, in other countries, and in other cultures. Full article
