In psychological research, comparisons between two groups are frequently made to demonstrate that one group exhibits higher values. Although Welch’s unequal variances t-test has become the preferred parametric test for this purpose, surpassing Student’s equal variances t-test, the Wilcoxon–Mann–Whitney test remains the predominant nonparametric approach despite sharing similar limitations with Student’s t-test. Specifically, the Wilcoxon–Mann–Whitney test is associated with strong, unrealistic assumptions and lacks robustness when these assumptions are violated. The Brunner–Munzel test overcomes these limitations, featuring fewer assumptions, akin to Welch’s t-test in the parametric domain, and has thus been recommended over the Wilcoxon–Mann–Whitney test. However, the Brunner–Munzel test is currently unavailable in user-friendly statistical software, such as SPSS, making it inaccessible to many researchers. In this paper, I introduce the bmtest module for jamovi, a freely available user-friendly software. By making the Brunner–Munzel test accessible to a wide range of researchers, the bmtest module has the potential to improve nonparametric statistical analysis in psychology and other disciplines.
在心理学研究中,经常对两组进行比较,以证明其中一组表现出更高的价值。尽管Welch’s不等方差t检验已经超越Student’s等方差t检验,成为首选的参数检验,但Wilcoxon-Mann-Whitney检验仍然是主要的非参数方法,尽管它与Student’s t检验有类似的局限性。具体来说,Wilcoxon-Mann-Whitney检验与强烈的、不切实际的假设有关,当这些假设被违反时,它缺乏稳健性。Brunner-Munzel检验克服了这些限制,具有较少的假设,类似于参数域的Welch t检验,因此被推荐为优于Wilcoxon-Mann-Whitney检验。然而,Brunner-Munzel检验目前在SPSS等用户友好的统计软件中是不可用的,这使得许多研究人员无法使用它。在本文中,我介绍了jamovi的测试模块,jamovi是一个免费的用户友好软件。通过将Brunner-Munzel测试提供给广泛的研究人员,bmtest模块有可能改善心理学和其他学科的非参数统计分析。

Applications and Extensions of Metric Stability Analysis 度量稳定性分析的应用与推广
Pub Date : 2023-05-04 DOI: 10.3390/psych5020025
L. Feuerstahler
Item response theory models and applications are affected by many sources of variability, including errors associated with item parameter estimation. Metric stability analysis (MSA) is one method to evaluate the effects of item parameter standard errors that quantifies how well a model determines the latent trait metric. This paper describes how to evaluate MSA in dichotomous and polytomous data and describes a Bayesian implementation of MSA that does not require a positive definite variance–covariance matrix among item parameters. MSA analyses are illustrated in the context of an oral-health-related quality of life measure administered before and after prosthodontic treatment. The R code to implement the methods described in this paper is provided.
项目反应理论模型和应用受到许多可变性来源的影响,包括与项目参数估计相关的误差。度量稳定性分析(MSA)是一种评估项目参数标准误差影响的方法,它量化了模型确定潜在特征度量的程度。本文描述了如何在二分数据和多分数据中评估MSA,并描述了MSA的贝叶斯实现,该实现不需要项目参数之间的正定方差-协方差矩阵。MSA分析是在修复治疗前后进行的口腔健康相关生活质量测量的背景下进行说明的。提供了实现本文中描述的方法的R代码。

Exploring Approaches for Estimating Parameters in Cognitive Diagnosis Models with Small Sample Sizes 小样本量认知诊断模型参数估计方法探讨
Pub Date : 2023-04-27 DOI: 10.3390/psych5020023

Cognitive diagnostic models (CDMs) are increasingly being used in various assessment contexts to identify cognitive processes and provide tailored feedback. However, the most commonly used estimation method for CDMs, marginal maximum likelihood estimation with Expectation–Maximization (MMLE-EM), can present difficulties when sample sizes are small. This study compares the results of different estimation methods for CDMs under varying sample sizes using simulated and empirical data. The methods compared include MMLE-EM, Bayes modal, Markov chain Monte Carlo, a non-parametric method, and a parsimonious parametric model such as Restricted DINA. We varied the sample size, and assessed the bias in the estimation of item parameters, the precision in attribute classification, the bias in the reliability estimate, and computational cost. The findings suggest that alternative estimation methods are preferred over MMLE-EM under low sample-size conditions, whereas comparable results are obtained under large sample-size conditions. Practitioners should consider using alternative estimation methods when working with small samples to obtain more accurate estimates of CDM parameters. This study aims to maximize the potential of CDMs by providing guidance on the estimation of the parameters.
认知诊断模型(CDM)越来越多地被用于各种评估环境中,以识别认知过程并提供量身定制的反馈。然而,CDM最常用的估计方法,具有期望-最大化的边际最大似然估计(MMLE-EM),在样本量较小时可能会遇到困难。本研究使用模拟和经验数据比较了不同样本量下CDM估计方法的结果。比较的方法包括MMLE-EM、Bayes模态、马尔可夫链蒙特卡罗、非参数方法和简约参数模型(如Restricted DINA)。我们改变了样本量,并评估了项目参数估计的偏差、属性分类的精度、可靠性估计的偏差和计算成本。研究结果表明,在低样本量条件下,替代估计方法比MMLE-EM更可取,而在大样本量情况下获得了可比较的结果。从业者在处理小样本时应考虑使用替代估计方法,以获得更准确的CDM参数估计值。本研究旨在通过提供参数估计指导,最大限度地发挥CDM的潜力。

Background: Currently, educational attainment has risen significantly among young people, causing changes in the labor market where skills have become more important. Thus, tertiary education has become an “essential vehicle” to develop high-level skills that would boost students’ professional, social, and personal lives. Methods: The aim of the survey is to study the effects of an intervention program based on two methodologies, service-learning and peer mentoring, to enhance the learn-to-learn and social skills of undergraduate students. The sample was composed of 69 undergraduate students of four different degrees. The methodological design adopted was quasi-experimental pretest–posttest. The intervention consisted of 955 mentoring sessions (878 one-to-one and 77 in groups) among the undergraduate students and students in compulsory education. The undergraduate students participated as mentors. Before, they had three sessions of training. Weekly mentoring sessions were spread out during out-of-school time for 90 min each. Results: The results show a few statistically significant differences in favor of the posttest phase in strategies for the learning and social skills of the participants. Conclusions: Although the program did not obtain the expected results, these outcomes agree with the other studies that investigate intervention programs that use service-learning and peer mentoring methodologies.

The present study validated the University Student Engagement Inventory (USEI) in the Arabic language (A) by assessing its factor structure, construct validity, reliability, and concurrent validity. A total of 864 Tunisian Physical Education and Sport students provided data which was used to perform exploratory and confirmatory factor analyses, using samples comprising 366 (aged 19–25 years) and 498 (aged 19–26 years) students, respectively. The A-USEI, grade-point average (GPA), and Physical Education Grit (PE–Grit) scales were completed via online surveys. The exploratory factor analysis revealed that the A-USEI had three dimensions. The confirmatory factor analysis indicated that the second-order model was more suitable than the first-order multi-factor model. Using the indicators for the second-order model, the three factors showed good reliability, with their average variance extracted (AVE) values reflecting sufficient validity. The correlation analyses between the two scales’ scores and the A-USEI scores showed a moderate correlation, confirming the adapted scale’s concurrent validity. The study concludes that A-USEI is a valid tool for assessing student engagement among Arabic students. In addition, the practical implications and directions for future research are discussed.
本研究通过评估阿拉伯语(A)大学生敬业度量表(USEI)的因素结构、构念效度、信度和并发效度对其进行了验证。共有864名突尼斯体育教育和体育学生提供了数据,用于进行探索性和验证性因素分析,使用的样本分别包括366名(19-25岁)和498名(19-26岁)学生。A-USEI、平均绩点(GPA)和体育毅力(PE-Grit)量表通过在线调查完成。探索性因子分析显示A-USEI具有三个维度。验证性因子分析表明,二阶模型比一阶多因素模型更适合。采用二阶模型的指标,三个因素均具有较好的信度,其平均方差提取(AVE)值具有足够的效度。两种量表的得分与a - usei得分的相关分析显示为中度相关,证实了改编量表的并发效度。该研究得出结论,a - usei是评估阿拉伯学生参与程度的有效工具。最后,对今后的研究方向和现实意义进行了讨论。

This article is an introduction to Cluster Optimized Proximity Scaling (COPS) aimed at practitioners, as well as a tutorial on the usage of the corresponding R package cops. COPS is a variant of multidimensional scaling (MDS) that aims at providing a clustered configuration while still representing multivariate dissimilarities faithfully. It subsumes most popular MDS versions as special cases. We illustrate the ideas, use, flexibility and versatility of the method and the package with data from clinical psychology on how modules of the Modular Approach to Therapy for Children (MATCH) are used by clinicians in the wild. We supplement the COPS analyses with density-based hierarchical clustering in the original space and faceting with support vector machines. We find that scaling with COPS gives a sensible and insightful spatial arrangement of the modules, allows easy identification of clusters of modules and provides clear facets of modules corresponding to the MATCH protocols. In that respect COPS works better than both standard MDS and clustering.
本文介绍了针对从业者的集群优化邻近缩放(COPS),以及关于相应R包COP使用的教程。COPS是多维缩放(MDS)的一种变体,其目的是提供聚类配置,同时仍然忠实地表示多元相异性。它包含了最流行的MDS版本作为特殊情况。我们用临床心理学的数据说明了该方法和包的思想、用途、灵活性和多功能性,这些数据说明了临床医生如何在野外使用儿童模块化治疗方法(MATCH)的模块。我们在原始空间中用基于密度的分层聚类和用支持向量机进行面对面分析来补充COPS分析。我们发现,使用COPS进行缩放可以提供模块的合理和深入的空间排列,允许轻松识别模块集群,并提供与MATCH协议相对应的模块的清晰方面。在这方面,COPS比标准MDS和集群都工作得更好。

Using Structural Equation Modeling to Reproduce and Extend ANOVA-Based Generalizability Theory Analyses for Psychological Assessments 使用结构方程模型再现和扩展基于ANOVA的心理评估泛化理论分析

Generalizability theory provides a comprehensive framework for determining how multiple sources of measurement error affect scores from psychological assessments and using that information to improve those assessments. Although generalizability theory designs have traditionally been analyzed using analyses of variance (ANOVA) procedures, the same analyses can be replicated and extended using structural equation models. We collected multi-occasion data from inventories measuring numerous dimensions of personality, self-concept, and socially desirable responding to compare variance components, generalizability coefficients, dependability coefficients, and proportions of universe score and measurement error variance using structural equation modeling versus ANOVA techniques. We further applied structural equation modeling techniques to continuous latent response variable metrics and derived Monte Carlo-based confidence intervals for those indices on both observed score and continuous latent response variable metrics. Results for observed scores estimated using structural equation modeling and ANOVA procedures seldom varied. Differences in reliability between raw score and continuous latent response variable metrics were much greater for scales with dichotomous responses, thereby highlighting the value of doing analyses on both metrics to evaluate gains that might be achieved by increasing response options. We provide detailed guidelines for applying the demonstrated techniques using structural equation modeling and ANOVA-based statistical software.
泛化理论为确定多种测量误差来源如何影响心理评估的分数提供了一个全面的框架,并利用这些信息来改进这些评估。尽管可推广性理论设计传统上使用方差分析(ANOVA)程序进行分析,但相同的分析可以使用结构方程模型进行复制和扩展。我们从测量人格、自我概念和社会期望反应的多个维度的清单中收集了多个场合的数据,以使用结构方程建模与方差分析技术比较方差分量、可推广性系数、可靠性系数以及宇宙得分和测量误差方差的比例。我们进一步将结构方程建模技术应用于连续潜在反应变量度量,并根据观察得分和连续潜在反应可变度量推导出这些指数的基于蒙特卡罗的置信区间。使用结构方程建模和方差分析程序估计的观察分数的结果很少变化。对于具有二分法反应的量表,原始得分和连续潜在反应变量指标之间的可靠性差异要大得多,从而突出了对这两个指标进行分析以评估通过增加反应选项可能实现的收益的价值。我们提供了使用结构方程建模和基于方差分析的统计软件应用演示技术的详细指南。

Scale Type Revisited: Some Misconceptions, Misinterpretations, and Recommendations 重新审视量表类型:一些误解、误解和建议

Stevens’s classification of scales into nominal, ordinal, interval, and ratio types is among the most controversial yet resilient ideas in psychological and educational measurement. In this essay, I challenge the notion that scale type is essential for the development of measures in these fields. I highlight how the concept of scale type, and of interval-level measurement in particular, is variously interpreted by many researchers. These (often unstated) differences in perspectives lead to confusion about what evidence is appropriate to demonstrate interval-level measurement, as well as the implications of scale type for research in practice. I then borrow from contemporary ideas in the philosophy of measurement to demonstrate that scale type can only be established in the context of well-developed theory and through experimentation. I conclude that current notions of scale type are of limited use, and that scale type ought to occupy a lesser role in psychometric discourse and pedagogy.
史蒂文斯将量表分为名义量表、序数量表、区间量表和比率量表,这是心理学和教育测量中最具争议性但最具弹性的观点之一。在这篇文章中,我对规模类型对于这些领域的措施发展至关重要的观点提出了质疑。我强调了许多研究人员如何对量表类型的概念,特别是区间水平测量的概念进行不同的解释。这些(通常未说明的)观点差异导致了对什么证据适合证明区间水平测量的困惑,以及量表类型对实践研究的影响。然后,我借鉴了当代计量哲学的思想,证明只有在发达的理论和实验的背景下才能建立量表类型。我的结论是,目前量表类型的概念用途有限,量表类型在心理测量话语和教育学中的作用应该较小。

Background: Leadership during the COVID-19 pandemic often manifested as a command-and-control style of leadership which had detrimental emotional impacts on staff particularly the nursing workforce. Organisational responsibility for staff wellbeing would be necessary in another pandemic and leadership emerged as a key indicator of the overall health of an organisation and its workforce. Leadership can have detrimental effects on staff wellbeing or it can greatly boost their ability to handle a crisis. We sought to explore the interrelationship between leadership and nurses wellbeing in an inner-city university hospital during the initial wave of the pandemic. Methods: Secondary analysis of interview data collected during a hospital-wide evaluation of barriers and facilitators to changes implemented to support the surge of COVID-19 related admissions during wave 1. Data were collected through semi-structured video interviews between May and July 2020. Interviews were analysed using Framework analysis Results: Thirty-one nurses participated including matrons (n=7), sisters (n=8) and specialist nursing roles (n=16). Three overarching themes were identified: impact on nurses, personal factors and organisational factors. The impact on nurses manifested as distress and fatigue. Coping and help-seeking behaviours were found to be the two personal factors which underpinned nurses wellbeing. The organisational factors that impacted nurses wellbeing included decision-making, duty and teamwork. Conclusions: The wellbeing of the workforce is pivotal to the health service, and it is mutually beneficial for patients, staff, and leaders. Addressing how beliefs and misconceptions around wellbeing are communicated, and accessing psychological support is a key priority to support nurses during pandemics.
背景:在新冠肺炎大流行期间,领导层通常表现为命令和控制的领导风格,这对员工,尤其是护理人员产生了有害的情绪影响。在另一场疫情中,组织对员工福祉的责任是必要的,领导力已成为衡量组织及其员工整体健康状况的关键指标。领导力可能会对员工的健康产生不利影响,也可能大大提高他们处理危机的能力。我们试图探索在疫情初期,市中心大学医院的领导能力与护士健康之间的相互关系。方法:对在第1波期间为支持新冠肺炎相关入院人数激增而实施的变革的障碍和推动者进行全医院评估期间收集的访谈数据进行二次分析。数据是在2020年5月至7月期间通过半结构化视频访谈收集的。使用框架分析对访谈进行分析结果:31名护士参与,包括护士长(n=7)、姐妹(n=8)和专业护理角色(n=16)。确定了三个总体主题:对护士的影响、个人因素和组织因素。对护士的影响表现为痛苦和疲劳。应对和求助行为被发现是支撑护士健康的两个个人因素。影响护士健康的组织因素包括决策、职责和团队合作。结论:员工的福祉对医疗服务至关重要,对患者、员工和领导都是互利的。解决如何传达关于幸福感的信念和误解,以及获得心理支持是在流行病期间支持护士的关键优先事项。
