Structural equation modeling (SEM) is an increasingly popular method for examining multivariate time series data. As in cross-sectional data analysis, structural misspecification of time series models is inevitable, and further complicated by the fact that errors occur in both the time series and measurement components of the model. In this article, we introduce a new limited information estimator and local fit diagnostic for dynamic factor models within the SEM framework. We demonstrate the implementation of this estimator and examine its performance under both correct and incorrect model specifications via a small simulation study. The estimates from this estimator are compared to those from the most common system-wide estimators and are found to be more robust to the structural misspecifications considered. 相似文献

The aim of this study was to propose a French Validation of the Competitive Aggressiveness and Anger Scale (FVCAAS). The instrument was developed from the original version, which is composed of two subscales (six items by subscales) assessing aggressiveness and anger in competitive athletes (CAAS, Maxwell & Moores, 2007). Four studies have been conducted with 1428 competitors. In the first study, the exploratory factor analysis extracted the two-factor structure from the original version, both with good internal consistency. The second study confirmed that the two-factor structure of the instrument was consistent with the original version and showed its partial invariance across genders. The third study demonstrated the temporal stability of the FVCAAS. In the fourth study, both concurrent and discriminant validities were confirmed, supporting the validity and reliability of the FVCAAS. The contributions of this study and limitations are discussed, together with perspectives for future studies of aggressiveness in competitive sports. 相似文献

HIV/AIDS‐related (HAR) stigma is still a prevalent problem in Sub‐Saharan Africa, and has been found to be related to mental health of HIV‐positive individuals. However, no studies in the Sub‐Saharan African context have yet examined the relationship between HAR stigma and mental health among HIV‐negative, HIV‐affected adults and families; nor have any studies in this context yet examined stigma as an ecological construct predicting mental health outcomes through supra‐individual (setting level) and individual levels of influence. Multilevel modeling was used to examine multilevel, ecological relationships between HAR stigma and mental health among child and caregiver pairs from a systematic, community‐representative sample of 508 HIV‐affected households nested within 24 communities in KwaZulu‐Natal, South Africa. Two distinct dimensions of HAR stigma were measured: individual stigmatizing attitudes, and perceptions of community normative stigma. Findings suggest that individual‐level HAR stigma significantly predicts individual mental health (depression and anxiety) among HIV‐affected adults; and that community‐level HAR stigma significantly predicts both individual‐level mental health outcomes (anxiety) among HIV‐affected adults, and mental health outcomes (PTSD and externalizing behavior scores) among HIV‐affected children. Differentiated patterns of relationships were found using the two different stigma measures. These findings of unique relationships identified when utilizing two conceptually distinct stigma measures, at two levels of analysis (individual and community) suggest that HAR stigma in this context should be conceptualized as a multilevel, multidimensional construct. These findings have important implications both for mental health interventions and for interventions to reduce HAR stigma in this context. 相似文献

风险决策和跨期决策与人类生存发展密切相关, 且两类决策在理论发展、行为效应及神经基础等方面具有相似性。为检验二者是否具有共同过程机制, 本研究以风险决策中的确定效应和跨期决策中的即刻效应为例, 采用眼动追踪技术比较了它们的局部、整体过程及模型拟合。辅以贝叶斯因子分析实验数据表明:二者的主要过程特征均相似, 且更符合非折扣模型假设; 二者在加工复杂程度等少数特征上有所不同; 确定和即刻信息在加工方向等特征上存在特异性。这表明二者可能具有共同的核心决策规则:两类决策更可能遵循非折扣模型预期的简捷、启发式规则, 而不是折扣模型所假设的补偿性、基于选项规则。本研究为建立两类决策的共同解释框架做出了有益尝试, 并为决策比较研究方法提供新的方向。 相似文献

Perception of emotion in the face is a key component of human social cognition and is considered vital for many domains of life; however, little is known about how this ability differs across the lifespan for men and women. We addressed this question with a large community sample (N?=?100,257) of persons ranging from younger than 15 to older than 60 years of age. Participants were viewers of the television show “Tout le Monde Joue”, and the task was presented on television, with participants responding via their mobile devices. Applying latent variable modeling, and establishing measurement invariance between males and females and across age, we found that, for both males and females, emotion perception abilities peak between the ages of 15 and 30, with poorer performance by younger adults and declining performance after the age of 30. In addition, we show a consistent advantage by females across the lifespan, which decreases in magnitude with increasing age. This large scale study with a wide range of people and testing environments suggests these effects are largely robust. Implications are discussed. 相似文献

Young children who attend out‐of‐home care (e.g., preschool) are more susceptible to infections than children who do not attend out‐of‐home care. Previous research suggests handwashing is effective in reducing risk of infection and illness. However, research suggests that individuals do not routinely wash their hands using methods that healthcare agencies, such as the Centers for Disease Control and Prevention, have determined best practice. We evaluated the effects of a multicomponent handwashing intervention package on correct handwashing across groups of preschool children. Furthermore, we measured the degree to which their hands were clean using premeasures and postmeasures. Results suggest the intervention package was effective at increasing both correct handwashing and cleanliness of participants' hands. 相似文献

This study used a support gap approach to examine parental support to college‐going emerging adults. Based on data from 156 parent–child dyads, this study investigated whether discrepancies between the amounts of support that children received from parents and what they desired would be associated with both persons’ perceived support quality and individual and relational well‐being. Using polynomial regressions with response surface modeling, analyses demonstrated that, generally, support deficits (i.e., receiving less support than desired) were associated with poorer outcomes. However, support surpluses (i.e., receiving more support than desired) were not necessarily problematic, and children and parents exhibited different viewpoints regarding support surpluses. In addition, child‐reported support quality mediated several associations between support gaps and relationship satisfaction reported by both persons. 相似文献

The development of job satisfaction during the first months on the job often indicates a honeymoon hangover, with high levels of job satisfaction gradually declining. This effect is often explained by disappointed expectations that are informed by previous job experiences. However, research has not established whether a hangover pattern could also be observed in individuals without previous work experience. We explored the development of job satisfaction with 4 assessment points across the first 4 months after starting vocational training among 357 Swiss adolescents. On average, a hangover pattern in job satisfaction was confirmed. Using person-centred growth mixture modelling, we identified two groups with distinct trajectories. Although a majority showed a hangover pattern, a third of participants showed stable, high job satisfaction. We presumed that adolescents with more contextual and personal resources (i.e., perceived social support, occupational self-efficacy, core self-evaluations, and perceived person–job fit) would be more likely to avoid a hangover pattern. Results confirmed that the two groups differed significantly in all these resources, with the high stable satisfaction group showing higher resources. The results illustrate the importance of a diverse set of resources to facilitate a positive trajectory of job satisfaction at the beginning of work life. 相似文献

Emotionally focused couple therapy (EFT) is an empirically validated attachment based approach to couple therapy. From an EFT perspective, sexual functioning is viewed within the context of an attachment bond, but sexual satisfaction in EFT has not been empirically tested. We examined self-reported sexual satisfaction across 24?months in a sample of 32 couples who received an average of 21 EFT sessions. We found that sexual satisfaction increased across six time points from pre to post therapy and across follow-up (6, 12, 18, and 24?months), and that decreases in attachment avoidance from pre to post therapy predicted increases in sexual satisfaction across time. These findings provide evidence that EFT may help couples improve their sexual satisfaction by reducing attachment avoidance in therapy. 相似文献
