Police officers are exposed to several operational and organizational stressors that significantly impact on their mental health. The COVID-19 pandemic was a new stressor that further exacerbated existing stressors, highlighting the need for a better understanding of its impact on the mental health of police officers. This study tested the hypothesis that occupational stressors and PTSD are serial mediators of the relationship between fear of COVID-19 and burnout. Two hundred Portuguese police officers completed an online survey that assessed their fear of COVID-19, exposure to operational and organizational stressors, PTSD, and burnout. The results of the serial mediation analysis indicated that not only do occupational stressors act as mediators between fear of COVID-19 and burnout but also that PTSD is a mediator. The findings of this study underscore the need for interventions to reduce the negative impact of operational and organizational stressors on the mental health of police officers. Furthermore, this study highlights the power of police institutions for prevention and intervention with these professionals. By recognizing the specific stressors that contribute to the development of PTSD and burnout, our study provides a foundation for the development of direct interventions that can help to minimize the adverse effects of these stressors
警官面临着若干对其心理健康产生重大影响的行动和组织压力。2019冠状病毒病大流行是一个新的压力源,进一步加剧了现有的压力源,突出表明需要更好地了解其对警察心理健康的影响。本研究验证了职业压力源和创伤后应激障碍是COVID-19恐惧与倦怠关系的串行中介的假设。200名葡萄牙警察完成了一项在线调查,评估了他们对COVID-19的恐惧、对操作和组织压力源的暴露、创伤后应激障碍和倦怠。序列中介分析结果表明,职业压力源在COVID-19恐惧与职业倦怠之间起中介作用,PTSD在职业压力源与职业倦怠之间起中介作用。本研究的结果强调需要采取干预措施,以减少业务和组织压力源对警察心理健康的负面影响。此外,本研究强调了警察机构在预防和干预这些专业人员方面的力量。通过识别导致PTSD和倦怠的特定压力源,我们的研究为直接干预的发展提供了基础,可以帮助减少这些压力源的不利影响

Currently, two-level Mokken scale analysis for clustered test data is being developed. This paper contributes to this development by providing model-fit procedures for two-level Mokken scale analysis. New theoretical insights suggested that the existing model-fit procedure from traditional (one-level) Mokken scale analyses can be used for investigating model fit at both level 1 (respondent level) and level 2 (cluster level) of two-level Mokken scale analysis. However, the traditional model-fit procedure requires some modifications before it can be used at level 2. In this paper, we made these modifications and investigated the resulting model-fit procedure. For two model assumptions, monotonicity and invariant item ordering, we investigated the false-positive count and the sensitivity count of the level 2 model-fit procedure, with respect to the number of model violations detected, and the number of detected model violations deemed statistically significant. For monotonicity, the detection of model violations was satisfactory, but the significance test lacked power. For invariant item ordering, both aspects were satisfactory.
目前正在开发针对聚类测试数据的两级Mokken量表分析。本文通过提供两级莫肯量表分析的模型拟合程序来促进这一发展。新的理论见解表明,传统(一级)Mokken量表分析的现有模型拟合程序可以用于研究两级Mokken量表分析的第一级(被调查者水平)和第二级(聚类水平)的模型拟合。然而,传统的模型拟合过程需要进行一些修改才能用于第2级。在本文中,我们进行了这些修改,并研究了由此产生的模型拟合过程。对于两个模型假设,即单调性和不变项目顺序,我们研究了2级模型拟合过程的假阳性计数和敏感性计数,涉及检测到的模型违规数量,以及检测到的模型违规数量被认为具有统计显著性。对于单调性,模型违例检测是令人满意的,但显著性检验缺乏效力。对于不变项排序,这两个方面都令人满意。

Bayesian Regularized SEM: Current Capabilities and Constraints 贝叶斯正则化SEM:当前的能力和限制
Pub Date : 2023-08-03 DOI: 10.3390/psych5030054
Sara van Erp
An important challenge in statistical modeling is to balance how well our model explains the phenomenon under investigation with the parsimony of this explanation. In structural equation modeling (SEM), penalization approaches that add a penalty term to the estimation procedure have been proposed to achieve this balance. An alternative to the classical penalization approach is Bayesian regularized SEM in which the prior distribution serves as the penalty function. Many different shrinkage priors exist, enabling great flexibility in terms of shrinkage behavior. As a result, different types of shrinkage priors have been proposed for use in a wide variety of SEMs. However, the lack of a general framework and the technical details of these shrinkage methods can make it difficult for researchers outside the field of (Bayesian) regularized SEM to understand and apply these methods in their own work. Therefore, the aim of this paper is to provide an overview of Bayesian regularized SEM, with a focus on the types of SEMs in which Bayesian regularization has been applied as well as available software implementations. Through an empirical example, various open-source software packages for (Bayesian) regularized SEM are illustrated and all code is made available online to aid researchers in applying these methods. Finally, reviewing the current capabilities and constraints of Bayesian regularized SEM identifies several directions for future research.
统计建模的一个重要挑战是平衡我们的模型如何很好地解释所调查的现象与这种解释的简约性。在结构方程建模(SEM)中,已经提出了在估计过程中添加惩罚项的惩罚方法来实现这种平衡。经典惩罚方法的另一种选择是贝叶斯正则化SEM,其中先验分布作为惩罚函数。存在许多不同的收缩先验,在收缩行为方面具有很大的灵活性。因此,不同类型的收缩前料已被提出用于各种各样的sem。然而,由于缺乏这些收缩方法的总体框架和技术细节,使得(贝叶斯)正则化扫描电镜领域以外的研究人员难以理解和在自己的工作中应用这些方法。因此,本文的目的是提供贝叶斯正则化SEM的概述,重点关注贝叶斯正则化已经应用的SEM类型以及可用的软件实现。通过一个实证例子,说明了用于(贝叶斯)正则化SEM的各种开源软件包,并在网上提供了所有代码,以帮助研究人员应用这些方法。最后,回顾了贝叶斯正则化扫描电镜目前的能力和局限性,确定了未来研究的几个方向。

Examining the Associations between Personal Protective Equipment, Training, Policy, and Acute Care Workers’ Psychological Distress during the COVID-19 Pandemic 研究新冠肺炎大流行期间个人防护装备、培训、政策和急性护理人员心理困扰之间的关系

Previous studies have demonstrated an association between low personal protective equipment (PPE) availability and high stress and anxiety among frontline healthcare workers during the COVID-19 pandemic. It is unclear how other factors, such as infection prevention and control (IPC) training and IPC policy support, correlate with workers’ distress. The current study explores these relationships. We conducted a secondary analysis of a public survey dataset from Statistics Canada. Acute care workers’ survey responses (n = 7379) were analyzed using structural equation modeling to examine relationships between features of the IPC work environment and acute care workers’ ratings of their stress and mental health. We found that PPE availability (β = −0.16), workplace supports (i.e., training, IPC policy compliance, and enforcement) (β = −0.16), and support for staying home when sick (β = −0.19) were all negatively correlated with distress. Together, these features explained 18.4% of the overall variability in workers’ distress. Among surveyed acute care workers, PPE availability was related to their distress; however, having workplace support and an emphasis on staying home when sick was also relevant. Overall, the results highlight that, in addition to PPE availability, workplace supports and emphasis on staying home are important. IPC professionals and healthcare leaders should consider these multiple features as they support acute care workers during future infectious disease outbreaks.
先前的研究表明,在新冠肺炎大流行期间,一线医护人员的个人防护装备(PPE)可用性低与压力和焦虑高之间存在关联。目前尚不清楚其他因素,如感染预防和控制(IPC)培训和IPC政策支持,如何与工人的痛苦相关。目前的研究探讨了这些关系。我们对加拿大统计局的一个公共调查数据集进行了二次分析。使用结构方程模型分析了急性护理人员的调查反应(n=7379),以检验IPC工作环境的特征与急性护理人员对其压力和心理健康的评分之间的关系。我们发现,个人防护装备的可用性(β=−0.16)、工作场所支持(即培训、IPC政策遵守和执行)(β=–0.16)和生病时呆在家里的支持(β=-0.19)都与痛苦呈负相关。这些特征共同解释了18.4%的工人痛苦的总体变异性。在接受调查的急性护理工作者中,个人防护装备的可用性与他们的痛苦有关;然而,获得工作场所的支持和强调生病时呆在家里也很重要。总的来说,研究结果强调,除了个人防护装备的可用性外,工作场所的支持和对呆在家里的重视也很重要。IPC专业人员和医疗保健领导者在未来传染病爆发期间支持急性护理人员时,应考虑这些多重特征。

The detection of pain in persons with advanced dementia is challenging due to their inability to verbally articulate the pain they are experiencing. Pain Assessment in Advanced Dementia (PAINAD) is an observer-rated pain assessment tool developed based on non-verbal expressions of pain for persons with severe dementia. This study aimed to perform construct validation of PAINAD for pain assessment in persons with severe dementia in Malaysia. This was a prospective cross-sectional study conducted from 27 April 2022 to 28 October 2022 in eight public hospitals in Malaysia. The PAINAD scale was the index test, and the Discomfort Scale—Dementia of the Alzheimer Type (DS-DAT) and Nurse-Reported Pain Scale (NRPS) were the reference tests for construct and concurrent validity assessment. Pain assessment for the study subjects was performed by two raters concurrently at rest and during activity. The PAINAD score was determined by the first rater, whereas the DS-DAT and NRPS were assessed by the second rater, and they were blinded to each other’s findings to prevent bias. PAINAD showed good positive correlations ranging from 0.325 to 0.715 with DS-DAT and NRPS at rest and during activity, with a p-value of <0.05. It also demonstrated statistically significant differences when comparing pain scores at rest and during activity, pre- and post-intervention. In conclusion, the PAINAD scale is a reliable observer-rated pain assessment tool for persons with severe dementia in Malaysia. It is also sensitive to changes in the pain level during activity and at rest, pre- and post-intervention.
晚期痴呆症患者的疼痛检测是具有挑战性的,因为他们无法口头表达他们正在经历的疼痛。晚期痴呆患者疼痛评估(PAINAD)是一种基于非语言表达的重度痴呆患者疼痛评估工具。本研究旨在对马来西亚重度痴呆患者进行疼痛评估的PAINAD进行结构验证。这是一项前瞻性横断面研究,于2022年4月27日至2022年10月28日在马来西亚的八家公立医院进行。以PAINAD量表为指标测试,以老年痴呆症不适量表(DS-DAT)和护士报告疼痛量表(NRPS)为参考测试进行结构效度评估和并发效度评估。研究对象的疼痛评估由两名评分员在休息和活动时同时进行。PAINAD评分由第一评分者决定,而DS-DAT和NRPS评分由第二评分者评估,并且他们对彼此的结果是盲目的,以防止偏见。在休息和活动时,PAINAD与DS-DAT和NRPS呈0.325 ~ 0.715的良好正相关,p值<0.05。在比较休息时和活动时、干预前和干预后的疼痛评分时,也显示出统计学上的显著差异。总之,PAINAD量表是马来西亚重度痴呆患者的可靠的观察者评价疼痛评估工具。它对活动和休息时、干预前后疼痛水平的变化也很敏感。

This study aims to introduce Bayesian Knowledge Tracing (BKT), a probabilistic model used in educational data mining to estimate learners’ knowledge states over time. It also provides a practical guide to estimating BKT models using the pyBKT library available in Python. The first section presents an overview of BKT by explaining its theoretical foundations and advantages in modeling individual learning processes. In the second section, we describe different variants of the standard BKT model based on item response theory (IRT). Next, we demonstrate the estimation of BKT with the pyBKT library in Python, outlining data pre-processing steps, parameter estimation, and model evaluation. Different cases of knowledge tracing tasks illustrate how BKT estimates learners’ knowledge states and evaluates prediction accuracy. The results highlight the utility of BKT in capturing learners’ knowledge states dynamically. We also show that the model parameters of BKT resemble the parameters from logistic IRT models.

Accurate Standard Errors in Multilevel Modeling with Heteroscedasticity: A Computationally More Efficient Jackknife Technique 异方差多水平模型的精确标准误差:一种计算效率更高的折刀技术
Pub Date : 2023-07-21 DOI: 10.3390/psych5030049
Steffen Zitzmann, Sebastian Weirich, Martin Hecht
In random-effects models, hierarchical linear models, or multilevel models, it is typically assumed that the variances within higher-level units are homoscedastic, meaning that they are equal across these units. However, this assumption is often violated in research. Depending on the degree of violation, this can lead to biased standard errors of higher-level parameters and thus to incorrect inferences. In this article, we describe a resampling technique for obtaining standard errors—Zitzmann’s jackknife. We conducted a Monte Carlo simulation study to compare the technique with the commonly used delete-1 jackknife, the robust standard error in Mplus, and a modified version of the commonly used delete-1 jackknife. Findings revealed that the resampling techniques clearly outperformed the robust standard error in rather small samples with high levels of heteroscedasticity. Moreover, Zitzmann’s jackknife tended to perform somewhat better than the two versions of the delete-1 jackknife and was much faster.
在随机效应模型、层次线性模型或多层模型中,通常假设高层单元内的方差是同方差的,这意味着它们在这些单元之间是相等的。然而,这一假设在研究中经常被违背。根据违反的程度,这可能导致更高级别参数的偏差标准误差,从而导致不正确的推断。在这篇文章中,我们描述了一种获得标准误差的重采样技术——齐兹曼折刀。我们进行了蒙特卡罗模拟研究,将该技术与常用的delete-1折刀、Mplus中的鲁棒标准误差以及常用的delete-1折刀的改进版本进行了比较。研究结果表明,在具有高水平异方差的相当小的样本中,重采样技术明显优于稳健的标准误差。此外,Zitzmann的折刀比两个版本的delete-1折刀表现得更好,速度也快得多。

However, this assumption is often violated in research. Depending on the degree of violation, this can lead to biased standard errors of higher-level parameters and thus to incorrect inferences. In this article, we describe a resampling technique for obtaining standard errors—Zitzmann’s jackknife. We conducted a Monte Carlo simulation study to compare the technique with the commonly used delete-1 jackknife, the robust standard error in Mplus, and a modified version of the commonly used delete-1 jackknife.

Gratitude has been extensively studied over the past two decades. Among several predictors, aspects of religiosity and spirituality have been consistent predictors of gratitude. To explore the religious motivations and processes that foster the practice of gratitude, we undertook a systematic thematic analysis using interview data from a national qualitative project of 198 highly religious families. Participants (n = 476) included mothers, fathers, and children from various socioeconomic backgrounds and from diverse religious, racial, and ethnic backgrounds in the United States of America. Semi-structured interviews were conducted in the participants’ homes. Data for this study were analyzed using a team-based approach to qualitative analysis. The findings were organized thematically, including: (a) aspects of gratitude, (b) expressions of gratitude, and (c) the influence of gratitude. Two aspects of gratitude were identified: functional—what people were grateful for—and directional—to whom they were grateful. Expressions of gratitude involved participation in regular, gratitude-focused prayers and mutual day-to-day appreciation. The relational context and implications and context of gratitude in religious families were further examined and reported with sub-themes: (a) gratitude prompted positive re-evaluation of relationships and (b) gratitude reinforced religious faith. Implications, strengths, limitations, and future directions are discussed.
在过去的二十年里,人们对感恩进行了广泛的研究。在几个预测因素中,宗教信仰和精神方面一直是感恩的预测因素。为了探索促进感恩实践的宗教动机和过程,我们使用来自198个高度宗教化家庭的国家定性项目的访谈数据进行了系统的主题分析。参与者(n=476)包括来自美利坚合众国不同社会经济背景以及不同宗教、种族和民族背景的母亲、父亲和儿童。半结构化访谈在参与者家中进行。本研究的数据采用基于团队的定性分析方法进行分析。研究结果按主题组织,包括:(a)感恩的各个方面,(b)感恩的表达,以及(c)感恩的影响。感恩的两个方面被确定:功能性的——人们感激的东西——和定向的——他们感激的人。表达感激之情包括定期参加以感恩为重点的祈祷和日常相互感激。进一步研究并报告了宗教家庭中感恩的关系背景、含义和背景,分主题为:(a)感恩促使对关系进行积极的重新评估;(b)感恩强化了宗教信仰。讨论了影响、优势、局限性和未来方向。

Contemporary Mirror Imaging between American and Iranian Citizens: An Exploratory Mixed-Method Research Study 当代美国与伊朗公民镜像研究——探索性混合方法研究
Pub Date : 2023-07-20 DOI: 10.3390/psych5030047

In this study, an exploratory mixed-method approach was employed to investigate the attitudes of Iranians and Americans toward each other, specifically focusing on two critical incidents in their modern history. Drawing from quantitative and qualitative data collected in relation to the hostage crisis in 1979, the missile attack on an Iranian passenger plane (Iran Air 655) in 1988, and the travel ban (Executive Order 13780) in 2018, the study aimed to uncover any changes in attitudes over the course of history. Unlike previous research, the majority of participants had a more balanced and less biased viewpoint toward each other and approached the incidents by considering the consequences and ethical aspects associated with each event. These findings challenge the notion of a mirror image effect, which suggests that people tend to adopt their government’s attitude toward other nations. Instead, participants demonstrated a tendency to rely on their own judgment and critically evaluate information, rather than blindly accepting media narratives.
在本研究中,采用一种探索性的混合方法来调查伊朗人和美国人对彼此的态度,特别关注他们现代史上的两个关键事件。该研究收集了1979年人质危机、1988年导弹袭击伊朗客机(伊朗航空655号)和2018年旅行禁令(第13780号行政命令)相关的定量和定性数据,旨在揭示历史进程中态度的任何变化。与之前的研究不同,大多数参与者对彼此的看法更加平衡,偏见更少,并且通过考虑与每个事件相关的后果和道德方面来处理事件。这些发现挑战了镜像效应的概念,即人们倾向于采用本国政府对其他国家的态度。相反,参与者表现出依赖自己的判断和批判性地评估信息的倾向,而不是盲目地接受媒体的叙述。
