Structural equation models are increasingly used as a modeling tool for multivariate time series data in the social and behavioral sciences. Standard error estimators of SEM models, originally developed for independent data, require modifications to accommodate the fact that time series data are inherently dependent. In this article, we extend a sandwich-type standard error estimator of independent data to multivariate time series data. One required element of this estimator is the asymptotic covariance matrix of concurrent and lagged correlations among manifest variables, whose closed-form expression has not been presented in the literature. The performance of the adapted sandwich-type standard error estimator is evaluated using a simulation study and further illustrated using an empirical example.  相似文献

This paper first discusses the relationship between Kullback–Leibler information (KL) and Fisher information in the context of multi-dimensional item response theory and is further interpreted for the two-dimensional case, from a geometric perspective. This explication should allow for a better understanding of the various item selection methods in multi-dimensional adaptive tests (MAT) which are based on these two information measures. The KL information index (KI) method is then discussed and two theorems are derived to quantify the relationship between KI and item parameters. Due to the fact that most of the existing item selection algorithms for MAT bear severe computational complexity, which substantially lowers the applicability of MAT, two versions of simplified KL index (SKI), built from the analytical results, are proposed to mimic the behavior of KI, while reducing the overall computational intensity.  相似文献

Previous research investigating attentional bias has produced intriguingly equivocal results. The present large-scale study explored attentional bias in subjects diagnosed with obsessive-compulsive disorder (OCD) and in a control group (n = 80) using the Emotional Stroop Test. Results clearly indicated poorer performances across the board amongst patients diagnosed with OCD compared to the control group, particularly in the case of anxiety-related stimuli. This paper discusses, in the light of current models of attentional bias towards threat in anxiety disorders, the processes whereby attentional bias towards anxiety stimuli might play a vital role in the causation and maintenance of OCD.  相似文献

Modern medicine serves a religious function for modern Americans as a conduit through which science can be applied directly to the human body. The first half of this paper will focus on the theoretical foundations for viewing medicine as a religious practice arguing that just as a hierarchical structured authoritarian church historically mediated access to God, contemporary Western medicine provides a conduit by which the universalizable truths of science can be applied to the human being thereby functioning as a new established religion. I will then illustrate the many parallels between medicine and religion through an analysis of rituals and symbols surrounding and embedded within the modern practice of medicine. This analysis will pay special attention to the primacy placed on secret interior knowledge of the human body. I will end by responding to the hope for a “secularization of American medicine,” exploring some of the negative consequences of secularization, and arguing that, rather than seeking to secularize, American medicine should strive to use its religious features to offer hope and healing to the sick, in keeping with its historically religious legacy.  相似文献

We examined associations between spiritual well-being and CAM use among 4,139 cancer survivors. We also explored the classification of religious/spiritual practices (R/S) as CAMs and alternative subscale structures of the Functional Assessment of Chronic Illness Therapy—Spiritual Well-being (FACIT-Sp). We evaluated three aspects of spirituality, Faith, Peace, and Meaning, and use of 19 CAMs in 5 domains. Mind–body methods were subdivided into R/S and non-R/S. All FACIT-Sp factors were associated with CAM use, but in different directions: Meaning and Faith were positively associated; Peace was negatively associated. Peace was negatively associated with R/S CAMs, but not non-R/S CAMs. The prevalence of CAM use dropped from 79.3 to 64.8% when R/S items were excluded. These findings confirm an association between spiritual well-being and CAM use, including some non-R/S CAMs, and provide evidence of the benefits of using the three-factor FACIT-Sp solution and treating R/S CAMs as a separate category.  相似文献

A growing body of research suggests that religion may exert a beneficial effect on both physical and mental health. Unfortunately, the rapid growth of this literature has made it difficult to get a clear picture of what has been accomplished. This issue is addressed by presenting a conceptual model that focuses on the needs that are satisfied by religion. In the process, an effort is made to show how this conceptual scheme can be used to add greater coherence to the field.  相似文献

Empathy has been inconsistently defined and inadequately measured. This research aimed to produce a new and rigorously developed questionnaire. Exploratory (n? = 640) and confirmatory (n? = 318) factor analyses were employed to develop the Questionnaire of Cognitive and Affective Empathy (QCAE). Principal components analysis revealed 5 factors (31 items). Confirmatory factor analysis confirmed this structure in an independent sample. The hypothesized 2-factor structure (cognitive and affective empathy) was tested and provided the best and most parsimonious fit to the data. Gender differences, convergent validity, and construct validity were examined. The QCAE is a valid tool for assessing cognitive and affective empathy.  相似文献
