    背景:育儿实践被描述为父母和亲子沟通所采用的实践,专注于以最好的方式抚养孩子,同时灌输文化,伦理,和个人价值观。在孩子的发展中具有重要意义的一种相似但不同的构造是父母的情感社会化。父母的情感社会化是父母与孩子之间关于孩子的情感体验的互动。这被认为是个人情感和社交能力发展的重要标志。在育儿实践方面有几个尺度。然而,父母情感社会化的量表,特别是考虑到青少年和年轻人的感知,尚未得到充分探索。
    方法:研究的目的是建立一种全面的工具,该工具能够测量感知的父母情感社会化(PPSE)。工具构造的过程,数据收集,和分析是在五个阶段完成的,包括审查现有工具和识别领域(阶段1);生成项目池(阶段2);内容有效性,面部有效性,和评估者间的可靠性(第3阶段);最后确定数据收集工具(第4阶段);以及数据收集和分析(第5阶段)。工具构建研究包括13-28岁的参与者,代表来自新德里学校和大学的青少年和年轻人,印度,以及Gwalior,中央邦,印度。使用的研究设计是横截面设计,数据是通过目的抽样收集的,包括男性(N=337)和女性(N=424)。探索性因素分析(EFA)用于检查可因式分解性和项目减少。
    结果:结果有助于将项目数量从160个减少到46个,包括内容有效性的过程,评分者间的可靠性,项目总统计量,和全民教育的因子负荷。保留了特征值3以上的因子,同时考虑了因子载荷0.50以上的项目。建立了一个良好的Cronbachα系数为0.88的整体工具,域感知为0.89、0.84和0.87,验收,和教练,分别。
    结论:构建的量表包括个人的积极和消极情绪,并试图理解育儿实践接受者的观点。这项研究有助于理解PPSE的现象,这也可能有助于提高人们对有效育儿做法的认识。
    BACKGROUND: Parenting practices have been described as the practices employed by a parent and the parent-child communication, with the focus on raising a child in the best possible manner while instilling cultural, ethical, and personal values. One similar yet different construct that holds significance in the development of a child is parental socialization of emotion. Parental socialization of emotion is the interaction between the parents and child regarding the emotional experience of the child. This has been considered an essential marker of the development of the emotional and social competence of an individual. There are several scales in the aspect of parenting practices. However, scales for parental socialization of emotion especially considering the perception of adolescents and young adults have yet to fully be explored.
    METHODS: The aim of the study is to establish a comprehensive tool that enables the measurement of perceived parental socialization of emotion (PPSE). The process of tool construction, data collection, and analysis was done in five phases that included reviewing existing tools and identification of domains (Phase 1); generation of an item pool (Phase 2); content validity, face validity, and inter-rater reliability (Phase 3); finalization of the tool for data collection (Phase 4); and data collection and analysis (Phase 5). The study for tool construction included participants from ages 13-28 years representing adolescents and young adults from schools and colleges located in New Delhi, India, as well as Gwalior, Madhya Pradesh, India. The research design used was a cross-sectional design, and the data were collected through purposive sampling, including males (N = 337) and females (N = 424). Exploratory factor analysis (EFA) was used to check the factorability and for item reduction.
    RESULTS: The results aided in reducing the number of items from 160 to 46 including the process of content validity, inter-rater reliability, item-total statistic, and factor loading of EFA. The factors above the eigenvalue of 3 were retained while items above the factor loading of 0.50 were taken into consideration. A good Cronbach\'s alpha coefficient of 0.88 for the overall tool was established, with 0.89, 0.84, and 0.87 for the domains Awareness, Acceptance, and Coaching, respectively.
    CONCLUSIONS: The scale constructed includes both the positive and negative emotions of an individual and tries to understand the perspective of the receiver of the parenting practice. The study helps in understanding the phenomenon of PPSE, which might also aid in creating awareness regarding efficient parenting practices.

    目的:已引入自动药物分配系统(ADD)以提高分配效率和患者安全性。可用的问卷测量患者对ADD特定方面的满意度。此外,患者对ADDs的满意度水平尚未广泛确定.这项研究旨在开发和验证一种新颖的问卷,以评估患者对ADD的满意度。
    方法:使用内容和结构效度程序来验证包含四个领域的20项问卷,包括药房管理,配药实践,患者教育,和分配系统。两百名同意的参与者参加了这项研究,来自参观政府医院门诊药房的人。
    结果:所有四个量表项目的内部一致性均显示出可接受的可靠性(>0.7)。在探索性因素分析中,由于因子加载和交叉加载不良,三个项目被删除。在验证性因素分析中,该模型具有可接受的拟合指数,包括比较拟合指数(0.937),塔克-刘易斯指数(0.924),标准化均方根残差(0.051),近似均方根误差(0.057),和χ2/df(1.67)。建立了收敛效度和判别效度,因为提取的平均方差(AVE)≥0.5,并且一个构建体与其他构建体的平方相关(SC)值小于特定构建体的AVE。
    结论:本研究提供了一个可靠且有效的17项问卷,结合了多维四因素模型来评估患者对ADD的满意度。经过验证的问卷可用于探索患者对ADD的看法。
    OBJECTIVE: Automated drug dispensing systems (ADDs) have been introduced to improve the efficiency of dispensing and patient safety. The available questionnaires measure patient satisfaction with particular aspects of ADDs. Also, the level of patient satisfaction with ADDs is not widely established. This study aimed to develop and validate a novel questionnaire to assess patient satisfaction with ADDs.
    METHODS: Content and construct validity procedures were used to validate the 20-item questionnaire with four domains, including pharmacy administration, dispensing practice, patient education, and the dispensing system. Two hundred consenting participants took part in this study, from those who visited the outpatient pharmacy in a government hospital.
    RESULTS: The internal consistency of all four scale items shows acceptable reliability (>0.7). In the exploratory factor analysis, three items were removed due to poor factor loading and cross-loading. In the confirmatory factor analysis, the model has acceptable fit indices, including the comparative fit index (0.937), Tucker-Lewis\'s index (0.924), standardized root mean square residual (0.051), root mean square error of approximation (0.057), and χ2/df (1.67). The convergent and discriminant validity were established, since the average variance extracted (AVE) was ≥0.5 and the squared correlation (SC) values of one construct with other constructs were less than the AVE of the specific construct.
    CONCLUSIONS: This study offered a reliable and valid 17-item questionnaire incorporating a multi-dimensional four-factor model to evaluate patient satisfaction with ADDs. The validated questionnaire can be utilized to explore patients\' perspectives on ADDs.

    电子尼古丁输送系统(“电子烟”)是青少年最常用的尼古丁产品。Research,治疗,政策可以受益于青少年对使用结果的电子烟信念的衡量(即,预期)。在目前的研究中,我们开发并测试了青少年电子尼古丁雾化预期指标。
    一个青少年焦点小组评估了潜在的电子烟预期项目。一个国家专家小组协助修订了这些项目。最后,对14-17岁的青少年样本进行了研究(N=267,平均年龄15.6,SD=1.1,50.9%女性,50.2%非西班牙裔白人22.5%非西班牙裔黑人,14.2%的西班牙裔)在美国东南大都市地区。
    探索性因素分析揭示了四个因素的解决方案:负后果(Cronbach'sα=.92);正增强(α=.83);负影响减少(α=.95);和体重控制(α=.89)。子量表与蒸发敏感性和终生蒸发显着相关。子量表成功区分易感青少年和确认的非易感青少年,易感青少年报告更积极的期望,例如,积极强化,M=5.0,SD=2.0vsM=3.0,SD=2.1,P<.001,η2=0.19,负面预期较小,M=5.5,SD=2.3vsM=6.5,SD=2.6,P=.001,η2=0.04。发现类似的结果,比较从未吸过尼古丁的青少年和吸过尼古丁的青少年。分层线性回归表明,在控制人口统计学后,子量表是寿命蒸发的重要预测因子,vaping广告曝光,和同伴/家庭vaping。
    根据专家的输入和对青少年的试点测试,青少年预期指标的初步版本似乎是可靠和有效的。在并发有效性领域中发现了有希望的结果,判别效度,和增量有效性。未来的研究和评估工作将能够使用此工具来进一步实现预防和治疗目标。
    UNASSIGNED: Electronic nicotine delivery systems (\"e-cigarettes\") are the nicotine product most commonly used by adolescents. Research, treatment, and policy could benefit from measures of adolescent e-cigarette beliefs about outcomes of use (ie, expectancies). In the current study, we developed and tested an adolescent electronic nicotine vaping expectancy measure.
    UNASSIGNED: A focus group with adolescents evaluated potential e-cigarette expectancy items. A panel of national experts assisted in revision of these items. Finally, items were administered to a sample of adolescents 14-17 years old (N = 267, Mean age 15.6, SD = 1.1, 50.9% Female, 50.2% Non-Hispanic White, 22.5% Non-Hispanic Black, 14.2% Hispanic) in a large Southeastern metropolitan area in the United States.
    UNASSIGNED: Exploratory Factor Analysis revealed a four factor solution: Negative Consequences (Cronbach\'s α = .92); Positive Reinforcement (α = .83); Negative Affect Reduction (α = .95); and Weight Control (α = .89). Subscales were significantly correlated with vaping susceptibility and lifetime vaping. Subscales successfully differentiated susceptible adolescents from confirmed non-susceptible adolescents, with susceptible adolescents reporting more positive expectancies, eg, Positive Reinforcement, M = 5.0, SD = 2.0 vs M = 3.0, SD = 2.1, P < .001, η2 = 0.19, and less negative expectancies, M = 5.5, SD = 2.3 vs M = 6.5, SD = 2.6, P = .001, η2 = 0.04. Similar results were found comparing adolescents who have never vaped nicotine with those who have vaped nicotine. Hierarchical linear regression demonstrated subscales were significant predictors of lifetime vaping after controlling for demographics, vaping ad exposure, and peer/family vaping.
    UNASSIGNED: A preliminary version of an adolescent expectancy measure appears reliable and valid based on expert input and pilot testing with adolescents. Promising results were found in the domains of concurrent validity, discriminant validity, and incremental validity. Future research and evaluation efforts will be able to use this tool to further prevention and treatment goals.

    中国老年移民人口呈上升趋势,这对国家公共卫生服务体系提出了挑战。然而,公共卫生服务利用的异质性及其与社会融合的关系仍不清楚。本研究旨在探讨公共卫生服务利用的异质性及其与社会融合的关系。
    2017年中国移民动态调查(CMDS)的6,178名老年移民被纳入本研究。探索性因素分析用于将社会融合分为四个维度。潜在类别分析(LCA)用于识别公共卫生服务利用的不同亚组。采用方差分析和多因素logistic回归分析不同亚组的特征。
    确定了三个潜在的公共卫生服务利用类别:基本公共卫生服务利用率低(N=3,264,52.756%),基本公共卫生服务类别的中等利用率(N=1,743,28.172%),基本公共卫生服务类别利用率高(N=1,180,19.072%)。性别,教育,流动性的程度,独自行动与否,流动时间都是公共卫生服务利用类别的预测因素。不同潜在类别的社会融合存在显著差异(p<0.0001)。
    老年移民对公共卫生服务的利用受到许多方面的影响。社会融合作为公共卫生服务利用的重要影响因素值得关注。政府应关注老年移民的特点,有针对性地制定相关政策,以提高老年移民的公共卫生服务利用率。
    UNASSIGNED: The older adult migrant population in China is on the rise, which presents challenges for the national public health service system. However, the heterogeneity of public health service utilization and its relationship with social integration among the older adult migrant population remains unclear. This study aims to explore the heterogeneity the public health service utilization and how it relates to their social integration.
    UNASSIGNED: A total of 6,178 older adult migrants from the China Migrants Dynamic Survey (CMDS) in 2017 were included in this study. Exploratory factor analysis was used to categorize social integration into four dimensions. Latent class analysis (LCA) was used to identify different sub-groups of public health service utilization. ANOVA and multivariate logistic regression were used to determine the characteristics of different sub-groups.
    UNASSIGNED: Three potential classes of public health service utilization were identified: low utilization of basic public health services class (N = 3,264,52.756%), medium utilization of basic public health services class (N = 1,743,28.172%), and high utilization of basic public health services class (N = 1,180,19.072%). Gender, education, extent of mobility, and move alone or not, flow time were all predictors of the class of public health service utilization. There were significant differences in social integration across potential categories (p<0.0001).
    UNASSIGNED: The utilization of public health services of the older adult migrants is affected by many aspects. Social integration deserves attention as a significant influencing factor in the utilization of public health services. The government should pay attention to the characteristics of the older adult migrants and formulate relevant policies in a targeted manner in order to improve the utilization of public health services of the older adult migrants.

    BACKGROUND: Given increases in China\'s aging population, the growing demand for public health services and the shortage of human resources among nurses have become more prominent. Under such a background, \"Internet + Nursing Services\" have received more attention. Thus, exploring the barriers to and facilitators of nurses\' willingness to participate in \"Internet + Nursing Services\" and utilizing internet technology to increase the supply of nursing services has become a key issue.
    OBJECTIVE: This study aimed to develop a scale for assessing the barriers to and facilitators of nurses\' willingness to participate in \"Internet + Nursing Services\" and to test the validity and reliability of the scale.
    METHODS: A preliminary scale was developed based on a literature review, theoretical research, semistructured qualitative interviews, and two rounds of Delphi expert inquiry. A convenient sampling method was used for the questionnaire survey. A 5-point Likert scale was used to evaluate the importance of the items. The survey data of 659 clinical nurses obtained from February to March 2023 were used for item analysis, exploratory factor analysis (EFA), and reliability and validity tests of the scale. The survey data of 538 clinical nurses obtained in April 2023 were used for confirmatory factor analysis (CFA) of the final scale.
    RESULTS: The final scale consists of 25 items and 4 dimensions (performance expectations, perceived risk, need for professional knowledge training, and nonprofessional knowledge training). The scale showed good structural validity and content validity: the Cronbach\'s α coefficient of the scale was 0.955, the split-half reliability was 0.778, the test-retest reliability was 0.944, the kaiser-meyer-olkin(KMO) value was 0.960, and the cumulative variance contribution rate of the 4 common factors was 83.147%. The scale content validity index(S-CVI) was 0.914. The confirmatory factor analysis model had favorable fit indices: χ2/df = 4.234, RMSEA = 0.078, NFI = 0.940, IFI = 0.953, TLI = 0.947, and CFI = 0.953.
    CONCLUSIONS: The scale for assessing the barriers to and facilitators of nurses\' willingness to participate in \"Internet + Nursing Services\" has good reliability and validity, and provides a reference for evaluating nurses\' willingness to participate in \"Internet + Nursing Services\".

    西方文化的最新研究表明,情绪调节目标对心理健康具有重要意义。本研究旨在检验中国文化背景下情绪调节目标量表(ERGS)的因子结构。首先使用探索性因素分析(EFA)和验证性因素分析(CFA)来检查ERGS的因子结构,然后进行信度和效度测试以检查ERGS的心理测量学特性。结果表明,原始的五因素模型在EFA和CFA中均表现出拟合,因此被用于进一步的心理测量分析。这五个因素中的大多数与情绪调节倾向和负面情绪结果显着相关(例如,抑郁症),除了促享乐目标和表达抑制之间的非显著关联,以及抑郁的亲社会和印象管理目标。ERGS还显示出良好的内部一致性和半分割可靠性。然而,在这五个因素中,重测可靠性差异很大。享乐目标具有更高的重测可靠性,而逆势享乐主义者,性能,亲社会,印象管理目标显示出较低的价值,尤其是后两者。简而言之,ERGS在评估中国文化背景下的情绪调节目标方面表现出了有希望的五因素结构。
    Recent studies in Western cultures suggested emotion regulation goals have important implications for mental health. This study aimed to test the factor structure of Emotion Regulation Goals Scale (ERGS) in a Chinese cultural context. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were first used to examine the factor structure of the ERGS, and then reliability and validity tests were conducted to examine the psychometric properties of the ERGS. Results showed that the original five-factor model demonstrated fit during both EFA and CFA, and was thus adopted for further psychometric analyses. Most of the five factors were significantly associated with emotion regulation tendencies and negative emotional outcomes (e.g., depression), except for the non-significant associations between pro-hedonic goals and expressive suppression, and pro-social and impression management goals with depression. The ERGS also showed good internal consistency and split-half reliability. However, the test-retest reliabilities varied substantially across the five factors. The pro-hedonic goal had a higher test-retest reliability, whereas the contra-hedonic, performance, pro-social, and impression management goals showed lower values, especially the latter two. In brief, the ERGS showed a promising five-factor structure in assessing emotion regulation goals in Chinese cultural context.

    背景:公开演讲是社区和大学样本中最普遍担心的情况之一。尽管广泛的理论模型和实证研究旨在描述公众演讲焦虑(PSA)的潜在因素,导致其发作的特定变量仍未完全表征。
    方法:这项研究涉及来自AmazonTurk调查的297名参与者,参与按受众规模区分的虚拟公共演讲场景,参与度,和房间空间尺寸。参与者的预期焦虑水平在这些场景中进行了定量评估,能够全面探索情境变量和PSA之间的相互作用,从而提供了一个框架来探索受众规模的影响,订婚,和PSA上的空间尺寸。
    结果:混合效应模型揭示了受众规模之间的显着相互作用,观众参与度,和房间空间尺寸。使用主轴因子分解和多元回归的进一步分析确定了三个主要因素:F1(参与大观众),F2(约束或评估焦虑),和F3(观众脱离接触)。这些因素显著预测PSA评分。
    结论:这项研究表明,PSA受到受众规模的复杂相互作用的影响,房间尺寸,和观众参与。该发现强调了将这些情境变量纳入经验调查和治疗干预措施的可行方法。具体来说,它引入了一个新颖的框架,用于相对于房间容量标准化受众规模。
    BACKGROUND: Public speaking is one of the most commonly feared situations reported in both community and university samples. Despite extensive theoretical models and empirical studies aimed at delineating the underlying factors of Public Speaking Anxiety (PSA), the specific variables contributing to its onset remain incompletely characterised.
    METHODS: The research involved 297 participants from an AmazonTurk survey, engaging with virtual public speaking scenarios differentiated by audience size, engagement levels, and room spatial dimensions. Participants\' anticipated anxiety levels were quantitatively assessed across these scenarios, enabling a comprehensive exploration of the interaction between situational variables and PSA, thereby providing a framework to explore the influence of audience size, engagement, and spatial dimensions on PSA.
    RESULTS: The mixed-effect model revealed a significant interaction among audience size, audience engagement, and room spatial dimensions. Further analyses using principal axis factoring and multiple regression identified three main factors: F1 (Engagement in a Large Audience), F2 (Confinement or Evaluation Anxiety), and F3 (Audience Disengagement). These factors significantly predict PSA scores.
    CONCLUSIONS: This study reveals that PSA is influenced by a complex interplay of audience size, room dimensions, and audience engagement. The finding underscores the viable way to incorporate these situational variables in both empirical investigations and therapeutic interventions. Specifically, it introduces a novel framework for standardising audience size relative to room capacity.

    结果:MLP-ANN模型优于标准逻辑线性回归模型,显示高精度(95%),精度(84%),和召回率(84%)在捕捉与人类态度有关的复杂心理问题。PFIA透露,设计可调性是影响牙科CAD软件用户满意度的最重要因素。XAI分析强调了支持终点线和皇冠设计的功能的积极影响,而设计步骤和安装时间的数量有负面影响。值得注意的是,与终点线设计相关的功能和设计步骤的数量成为最重要的因素。
    结论:本研究揭示了影响牙科专业人员使用和选择CAD软件决策的因素。这种方法可以作为在牙科和医学中应用基于DL-XAI的行为分析的概念证明。促进明智的软件选择和开发。
    OBJECTIVE: This study aimed to examine the satisfaction of dental professionals, including dental students, dentists, and dental technicians, with computer-aided design (CAD) software performance using deep learning (DL) and explainable artificial intelligence (XAI)-based behavioral analysis concepts.
    METHODS: This study involved 436 dental professionals with diverse CAD experiences to assess their satisfaction with various dental CAD software programs. Through exploratory factor analysis, latent factors affecting user satisfaction were extracted from the observed variables. A multilayer perceptron artificial neural network (MLP-ANN) model was developed along with permutation feature importance analysis (PFIA) and the Shapley additive explanation (Shapley) method to gain XAI-based insights into individual factors\' significance and contributions.
    RESULTS: The MLP-ANN model outperformed a standard logistic linear regression model, demonstrating high accuracy (95%), precision (84%), and recall rates (84%) in capturing complex psychological problems related to human attitudes. PFIA revealed that design adjustability was the most important factor impacting dental CAD software users\' satisfaction. XAI analysis highlighted the positive impacts of features supporting the finish line and crown design, while the number of design steps and installation time had negative impacts. Notably, finish-line design-related features and the number of design steps emerged as the most significant factors.
    CONCLUSIONS: This study sheds light on the factors influencing dental professionals\' decisions in using and selecting CAD software. This approach can serve as a proof-of-concept for applying DL-XAI-based behavioral analysis in dentistry and medicine, facilitating informed software selection and development.

    背景:美国成年人的代谢综合征(MetS)患病率从2011-12年的37.6%增加到2017-2018年的41.8%。环境暴露,特别是常见的化合物,如草甘膦,作为一个潜在的风险因素,已经引起了越来越多的关注。
    方法:我们在一项横断面研究中采用了来自国家健康与营养检查调查(NHANES)的三个数据周期(2013-2018),以检查尿液草甘膦测量与MetS发病率之间的潜在关联。我们首先使用国际糖尿病联合会(IDF)MetS标准的探索性因素分析(EFA)创建了MetS评分,根据2013-2018年NHANES周期的数据,并在其他相关指标上独立验证了此分数,白蛋白-肌酐(ACR)比率。该分数通过机器学习方法通过二元分类预测ACR分数进行验证,然后用于多变量回归以测试四分位数分类的草甘膦暴露与MetS分数之间的关联。
    结果:在调整后的多变量回归中,四分位数分类的草甘膦暴露与MetS评分之间的回归显示出明显的倒U形或饱和剂量反应曲线,通常对四分位数3中的曝光影响最大。按性别对潜在效应修正的探索,种族,年龄类别显示出种族和年龄的显著差异,老年人(年龄>65岁)和非西班牙裔非裔美国人参与者对所有暴露四分位数显示出较大的效应大小。
    结论:我们发现尿草甘膦浓度与旨在预测MetS状态的统计评分显着相关,并且剂量反应系数是非线性的,高龄和非西班牙裔非洲裔美国人,墨西哥裔美国人和其他西班牙裔参与者表现出更大的效果。
    BACKGROUND: The prevalence of metabolic syndrome (MetS) in American adults increased from 37.6% in the 2011-12 period to 41.8% in 2017-2018. Environmental exposure, particularly to common compounds such as glyphosate, has drawn increasing attention as a potential risk factor.
    METHODS: We employed three cycles of data (2013-2018) from the National Health and Nutrition Examination Survey (NHANES) in a cross-sectional study to examine potential associations between urine glyphosate measurements and MetS incidence. We first created a MetS score using exploratory factor analysis (EFA) of the International Diabetes Federation (IDF) criteria for MetS, with data drawn from the 2013-2018 NHANES cycles, and validated this score independently on an additional associated metric, the albumin-to-creatinine (ACR) ratio. The score was validated via a machine learning approach in predicting the ACR score via binary classification and then used in multivariable regression to test the association between quartile-categorized glyphosate exposure and the MetS score.
    RESULTS: In adjusted multivariable regressions, regressions between quartile-categorized glyphosate exposure and MetS score showed a significant inverted U-shaped or saturating dose‒response profile, often with the largest effect for exposures in quartile 3. Exploration of potential effect modification by sex, race, and age category revealed significant differences by race and age, with older people (aged > 65 years) and non-Hispanic African American participants showing larger effect sizes for all exposure quartiles.
    CONCLUSIONS: We found that urinary glyphosate concentration is significantly associated with a statistical score designed to predict MetS status and that dose-response coefficient is nonlinear, with advanced age and non-Hispanic African American, Mexican American and other Hispanic participants exhibiting greater effect sizes.
