BACKGROUND: This study aimed to investigate the cognitive and affective factors associated with cross-cultural differences in arithmetic tasks.
METHODS: A total of 404 third- and fourth- graders were recruited from China and Italy to complete exact arithmetic, arithmetic estimation and cognitive tasks (i.e., short-term memory, executive functions, and fluid reasoning). Their mathematical anxiety was also measured.
RESULTS: The results showed that Chinese children performed better than Italian children in both arithmetic tasks and in shifting task. Italian children performed better in visuospatial updating task and reported higher levels of mathematical anxiety than their Chinese peers. Multi-group path analyses showed that the patterns of relations among cognitive factors (i.e., short-term memory, inhibition and shifting), mathematical anxiety, and arithmetic performance were similar across groups. The only exception was that visuospatial updating uniquely predicted arithmetic estimation for Chinese but not for Italian children.
CONCLUSIONS: Chinese children outperformed their Italian peers in the exact arithmetic task, likely due to the greater emphasis on arithmetic fluency in Chinese mathematics education, both in schools and at home. They also had a slight advantage than Italian peers in the arithmetic estimation task. The unique link between updating and arithmetic estimation found in Chinese children but not Italian children suggests that, although arithmetic estimation is not emphasized in the curricula of either country, instruction and practice in exact arithmetic may enhance Chinese children\'s efficiency in solving arithmetic estimation problems.

The Spanish scale symptom questionnaire for visual dysfunctions (SQVD) was sinicized and tested for reliability and validity in the Chinese context, employing both classical measurement theory and item response theory. A meticulous translation was conducted using the modified Brislin translation model, with input from experts for cross-cultural debugging and in-depth review. Following a pre-survey study, the Chinese version of the SQVD was finalized. A convenience sampling method was used to select 270 patients from the target group and 252 valid questionnaires were successfully collected. The Rasch model was employed to assess response category functionality, fit statistics, unidimensionality, person and item reliability, separation, targeting, and differential item functioning. Classical test theory was applied to evaluate internal consistency and retest reliability, supplemented by correlation analysis. Job characteristic curves were also plotted to assess diagnostic accuracy. The Chinese SQVD conformed to a unidimensional structure with excellent reliability and validity. Person and item reliabilities were 0.85 and 0.99, respectively, indicating, high stability. Person and item separation indices were 2.37 and 11.54, respectively, signifying strong differentiation ability. Retest reliability was 0.917, further emphasizing the stability of the scale. The area under the receiver operating characteristic curve was 0.908 (95% CI: 0.854, 0.962), with a cutoff value of 7.5 and Youden index of 0.733, highlighting the scale\'s high diagnostic accuracy. The translated and culturally adapted Chinese SQVD demonstrated excellent psychometric properties. With streamlined items, short assessment time, and high efficiency, the scale is a stable and reliable clinical tool for detecting a variety of conditions related to refractive, regulatory, and binocular vision dysfunction.

BACKGROUND: Social support is widely recognized as a protective factor against psychological distress, especially for the elderly with chronic diseases. Therefore, effective tools for measuring social support are of great significance for both research and clinical practice. This study aims to cross-culturally adapt the German Social Support Scale (F-SozU) into Chinese and assess its psychometric properties among older adults with chronic diseases.
METHODS: A cross-sectional study was conducted in a Chinese tertiary hospital. Four hundred ninety-six older adults that were approached via a convenience sampling method completed the Chinese version of the F-SozU. Content validity was evaluated using the two-round Delphi method. Psychometric properties, including item analysis, content validity, structure validity, convergent and discriminant validity and reliability were examined.
RESULTS: The final version of C-F-SozU is a three-factor structure consisting of 23 items. All indicators of item analysis are acceptable. Adequate content validity was ensured by the expert panel (I-CVI = 0.80-1.00, S-CVI = 0.965) and participants. The confirmatory factor analysis model revealed that the factor structure of the C-F-SozU fitted the original scale (χ 2 /df = 2.088, CFI = 0.998, GFI = 0.943, TLI = 0.997, IFI = 0.998, RMSEA = 0.064 and SRMR = 0.043). The total Cronbach\'s α was 0.956, and the test-retest reliability coefficient was 0.887. The convergent validity (average variance extracted = 0.517-0.995) and discriminant validity were found to be satisfactory. No floor/ceiling effect was found.
CONCLUSIONS: The 23-item C-F-SozU demonstrates robust reliability and validity, rendering it a valuable instrument for evaluating social support among older adults with chronic diseases in China. The three-factor structure of the scale allows for a more detailed assessment of the social support, with the scores of each dimension and the total score being of significant reference value. More comprehensive studies may be required to confirm its effectiveness and applicability.

BACKGROUND: Wild food plants (WFPs) play an important role in the traditional dietary habits of various indigenous communities worldwide, particularly in mountainous regions. To understand the dynamics of food preferences, cross-cultural studies on food plants should be conducted across diverse ethnic groups in a given area. In this context, the current study investigated the use of WFPs by seven different cultural groups in the Kashmir Himalayan Region. In this area, people gather wild plants and their parts for direct consumption, traditional foods, or sale in local markets. Despite this reliance, documentation of the food system, especially concerning WFPs, is notably lacking. Hence, our research aimed to document WFPs, along with associated traditional ecological knowledge, and identify major threats to their long-term sustainability in Division Muzaffarabad.
METHODS: Through a comprehensive approach involving questionnaires, interviews, focus groups, and market surveys, we gathered data from 321 respondents. PCA was performed to analyze threats and plant use using \"factoextra\" in R software. Origin Pro was used to create a chord diagram, while R software was used to generate a Polar heat map. Additionally, a Venn diagram was created using Bioinformatics software.
RESULTS: The study included 321 informants, of whom 75.38% were men and 24.61% were women. In total, 113 plant taxa from 74 genera and 41 botanical families were reported. Polygonaceae and Rosaceae accounted for the majority (17 species each), followed by Lamiaceae (7 species). Leaves were the most used part as food sources (41.04%), followed by fruits (33.33%). Most of the species are consumed as cooked (46.46%) and as raw snacks (37.80%). A total of 47 plant species were collected and cooked as wild vegetables, followed by 40 species used as fruits. This study is the first to describe the market potential and ecological distribution of WFPs in the study area. Cross-comparison showed that utilization of WFPs varies significantly across the region and communities, including their edible parts and mode of consumption. Jaccard index (JI) value ranged from 5.81 to 25. Furthermore, the current study describes 29 WFPs and 10 traditional food dishes that have rarely been documented in Pakistan\'s ethnobotanical literature. Climate change, invasive species, expansion of agriculture, and plant diseases are some of the most significant threats to WFPs in the study area.
CONCLUSIONS: The older age group has more knowledge about WFPs compared to the younger generation, who are not interested in learning about the utilization of WFPs. This lack of interest in information about WFPs among the younger generation can be attributed to their limited access to markets and availability of food plants in the study area. Traditional gathering of food plants has been reduced in younger generations during recent years; therefore, it is crucial to develop effective conservation strategies. These efforts not only safeguard indigenous flora, food knowledge, and cultural heritage, but they also contribute to food security and public health by utilizing local wild foods in the examined area.

Wisdom is the hallmark of social judgment, but how people across cultures recognize wisdom remains unclear-distinct philosophical traditions suggest different views of wisdom\'s cardinal features. We explore perception of wise minds across 16 socio-economically and culturally diverse convenience samples from 12 countries. Participants assessed wisdom exemplars, non-exemplars, and themselves on 19 socio-cognitive characteristics, subsequently rating targets\' wisdom, knowledge, and understanding. Analyses reveal two positively related dimensions-Reflective Orientation and Socio-Emotional Awareness. These dimensions are consistent across the studied cultural regions and interact when informing wisdom ratings: wisest targets-as perceived by participants-score high on both dimensions, whereas the least wise are not reflective but moderately socio-emotional. Additionally, individuals view themselves as less reflective but more socio-emotionally aware than most wisdom exemplars. Our findings expand folk psychology and social judgment research beyond the Global North, showing how individuals perceive desirable cognitive and socio-emotional qualities, and contribute to an understanding of mind perception.

OBJECTIVE: This study translated the short nutrition literacy scale for young adults (18-35 years) into Chinese, examined its reliability and validity, and analyzed its influencing factors.
METHODS: The scale was translated using a modified Brislin translation model. A convenience sample of 508 cases was selected for the survey. Content validity, structural validity, Cronbach\'s alpha coefficient, and test-retest reliability were used to evaluate the scale\'s reliability and validity. To screen the factors influencing nutrition literacy in young people.
RESULTS: The Chinese version of the Item-Level Content Validity Index (I-CVI) was 0.833 ~ 1, and the Scale-Level Content Validity Index/Average (S-CVI/Ave) was 0.908. The cumulative variance contribution of the scale was 51.029%, and the model was generally well-fitted. The Cronbach\'s alpha coefficient and retest reliability of the scale were 0.826 and 0.818. The results showed that the level of education, mother\'s education, nutrition-related courses, and frequency of attention to nutritional health information were the factors influencing the nutritional literacy of young people.
CONCLUSIONS: The Chinese version of the S-NutLit Scale can effectively assess the nutrients of young Chinese people. Low levels of education, low levels of education of mothers, lack of exposure to nutrition-related courses, and low frequency of attention to nutritional health information can lead to lower levels of nutritional literacy among young people.

The development of health literacy in China is relatively slow, and there are fewer health literacy scales, which is difficult to measure. Therefore, this study aims to promote the development of health literacy in China through the translation and application of the European Health Literacy Survey Questionnaire (HLS-EU-Q47). The scale was translated into Chinese, back-translated, culturally adapted and finally subjected to psychometric evaluation. A multi-stage stratified sampling method was used to select 2504 residents to test the reliability and validity of a questionnaire on health literacy. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to evaluate the validity of the results, and the back consistency was calculated by Cronbach\'s alpha coefficient. The EFA revealed that health care, disease prevention and health promotion explained 78.68% of the total variance in health literacy. The scale and its subscales demonstrated strong internal consistency, with high Cronbach\'s alpha coefficients ranging from 0.947 to 0.983. CFA confirmed the three-factor model\'s goodness-of-fit for the Chinese population. The dimensions of healthcare, disease prevention and health promotion showed high convergent validity with an average variance extracted values ranging from 0.52 to 0.60 and composite reliability values ranging from 0.94 to 0.96. The reliable and valid Chinese version of the HLS-EU-Q47 (HLS19-Q47-CN) developed and evaluated in this study is an important tool for assessing health literacy levels in the Chinese population. Furthermore, as this tool has global applicability, it has the potential to assess health literacy levels across different countries, enabling practical international comparisons.

When thinking about possibility, one can consider both epistemic and deontic principles (i.e., physical possibility and permissibility). Cultural influences may lead individuals to weigh epistemic and deontic obligations differently; developing possibility conceptions are therefore positioned to be affected by cultural surroundings. Across two studies, 251 U.S. and Chinese 4-, 6-, and 8-year-olds sampled from major metropolitan areas in Texas and the Hubei, Sichuan, Gansu, and Guangdong Provinces judged the possibility of impossible, improbable, and ordinary events. Across cultures and ages, children judged ordinary events as possible and impossible events as impossible; cultural differences emerged in developing conceptions of improbable events. Whereas U.S. children became more likely to judge these events possible with age, Chinese children\'s judgments remained consistent with age: Chinese 4- to 8-year-olds judged these events to be possible ∼25% of the time. In Study 2, to test whether this difference was attributable to differential prioritization of epistemic versus deontic constraints, children also judged whether each event was an epistemic violation (i.e., required magic to happen) and a deontic violation (i.e., would result in someone getting in trouble). With age, epistemic judgments were increasingly predictive of possibility judgments for improbable events for U.S. children, and decreasingly so for Chinese children. Contrary to our predictions, deontic judgments were not predictive. We propose that cultural valuation of norms might shape children\'s developing intuitions about possibility. We discuss our findings in light of three accounts of possibility conceptions, suggesting ways to integrate cultural context into each.

BACKGROUND: Caregiver self-efficacy is crucial in improving patient outcomes and caregiver well-being, but there is a lack of suitable scales to assess this concept within the context of Chinese culture. This study aimed to cross-culturally translate the Caregiver Self-Efficacy in Contributing to Patient Self-Care (CSE-CSC) Scale and evaluate its psychometric properties using classical test theory and item response theory.
METHODS: The CSE-CSC scale was adapted using Brislin\'s translation model after obtaining authorization from the original author. A multicenter, cross-sectional study was conducted to assess the psychometric properties of this scale. Classical test theory was used to evaluate reliability (internal consistency, test-retest reliability), validity (content validity, structural validity, convergent validity), and floor and ceiling effects. Item response theory was employed to assess the fit of the rating scale model, reliability, item difficulties, and measurement invariance.
RESULTS: The translation and cultural adaptation process was completed. Classical test theory demonstrated good internal consistency (Cronbach\'s α = 0.935) and test-retest reliability (ICC from 0.784 to 0.829, p<0.001). The I-CVI and K* of each item ranged from 0.875 to 1.00 and 0.871 to 1.00. The first-order 2-factor model fit well (χ2/df = 3.71, RMSEA = 0.082, SRMR = 0.032, CFI = 0.973, TLI = 0.60). Convergent validity showed that the CSE-CSC scores had a strong positive correlation with three separate scales of the CC-SC-CII. There was no floor and ceiling effect in this scale. Rasch analysis showed that the CSE-CSC scale demonstrated a good fit to the rating scale model and exhibited excellent reliability (person/item separation index>2, person/item reliability coefficients>0.8). The Wright map showed that item difficulty matched the respondents\' measured abilities. The analysis of differential item functioning (DIF) showed that all items were comparable in gender.
CONCLUSIONS: This study indicated that the CSE-CSC scale had good reliability, validity, difficulty degree, and measurement invariance. The CSE-CSC scale can be used to measure caregiver self-efficacy of Chinese patients with multiple chronic conditions.

BACKGROUND: The effect of lifestyle factors on cognitive function related to four major noncommunicable diseases (NCDs) including diabetes, cardiovascular disease, cancer, and chronic respiratory diseases, and the relationship between these NCDs and cognitive function have not been fully studied. We aimed to investigate the longitudinal associations between these NCDs and cognitive function in middle-aged and older people, and the combined effects of lifestyle factors.
METHODS: By employing the data from three large-scale cohort studies from the U.S. Health and Retirement Study (2010-2019), English Longitudinal Study of Aging (2014-2019), and China Health and Retirement Longitudinal Study (2011-2019), this study carried out a multi-cohort analysis to 77, 210 participants. Fixed-effects regression models were used to examine associations between NCD status and cognitive function. Margin plots were used to illustrate the effect of lifestyle factors.
RESULTS: Our findings revealed the dose-dependent association between mounting these NCDs and declining cognitive performance, ranging from one NCD (β = -0.05, 95 % CI: -0.08 to -0.02) to four NCDs (β = -0.51, 95 % CI: -0.75 to -0.28). Decline in cognitive function associated with NCDs was exacerbated with physical inactivity, current smoking status, and an increase in unhealthy lifestyle behaviors.
CONCLUSIONS: The observational study design precludes causal interrogation of lifestyles and four NCDs on cognitive function.
CONCLUSIONS: An increasing number of these NCDs were dose-dependently associated with the decline in cognitive function score. Unhealthy lifestyle factors expedite decline in cognitive function linked to these NCDs.
