Abstract: Although administrative bodies such as community health centers have implemented various awareness campaigns to promote community understanding of mental health and to reduce the stigma associated with mental illness and disorder, there have been few reports that have quantitatively analyzed the effects of these campaigns in Japan. Therefore, this study was conducted for the purpose of developing the evaluative “Mental Illness and Disorder Understanding Scale (MIDUS)” for awareness campaigns and assessing its reliability and validity. A survey was conducted on 1 004 community residents using a self‐administered questionnaire. An assessment of the reliability and validity of the scale was then conducted. The Cronbach a coefficient of the MIDUS was 0.78, thus indicating adequate reliability. Factor analysis of the MIDUS revealed three factors: “Treatability of illness”, “Efficacy of medication” and “Social recognition of illness”. In addition, a significant correlation was observed between the MIDUS and existing scales, and fixed criterion‐based validity was demonstrated. The MIDUS utilizes items worded in the form of affirmative expressions so as to avoid promoting new bias. It was confirmed to be both reliable and valid, thereby suggesting its usefulness as an evaluative scale of awareness campaigns.  相似文献

This study investigated the relative contribution of personality vs. environmental factors to the genesis of the burnout syndrome. A sample of 221 nursing students in Hamburg, Germany, were administered a battery of personality measures prior to any training. They were later asked to rate various stressors encountered during their practical training on hospital wards and also in nursing school, general aspects of ward climate, the frequency of private life events, and their own well-being on standard measures of burnout. Data were collected at seven time points over a period of 3 years, including the initial assessment (T1-T7). Only complete data sets (N = 123) were used for the analyses. Burnout scores from T2 to T7 were predicted, on the one hand, by the 36 'dispositional' scales of the initial battery and, on the other hand, by a set of 18 'experience-oriented' scales from the later questionnaire's concurrent administration. Scales reflecting well-being were predicted better by experiences than by dispositions. With scales reflecting attitudes towards oneself and patients, respectively, it was the other way around. Thus, both dispositional and experiential views of burnout receive some support here. Intraindividual change in burnout scores could not be linked to dispositional or experiential variables.  相似文献

Concurrently administered personal and telephone surveys are compared to measure differences between the modes for identical questions. Speed of questioning is found to be greater in telephone interviews than personal interviews. The faster pace of telephone interviews is linked to shorter answers to open-ended items on the telephone. The tendency to reduce such responses is disproportionately exhibited by younger, affluent respondents who tend to provide detailed responses in personal interviews.  相似文献

In this paper, we consider the preliminary test approach for the estimation of the regression parameter in a multiple regression model under a multicollinearity situation. The preliminary test two-parameter estimators based on the Wald (W), likelihood ratio, and Lagrangian multiplier tests are given, when it is suspected that the regression parameter may be restricted to a subspace and the regression error is distributed with multivariate Student's t distribution. The bias and mean square error of the proposed estimators are derived and compared. The conditions of superiority of the proposed estimators are obtained. Finally, we conclude that the optimum choice of the level of significance becomes the traditional choice by using the Wald test.  相似文献

We consider two-sided Bayesian tolerance intervals, with approximate frequentist validity, for a future observation in balanced one-way and two-way nested random effects models. Probability matching conditions, specific to this problem, are derived in either case via a technique that involves inversion of approximate posterior characteristic functions. In addition to yielding probability matching priors for the present problem, these conditions are useful in evaluating certain other priors that have received attention in the literature.  相似文献

The article discusses alternative Research Assessment Measures (RAM), with an emphasis on the Thomson Reuters ISI Web of Science database (hereafter ISI). Some analysis and comparisons are also made with data from the SciVerse Scopus database. The various RAM that are calculated annually or updated daily are defined and analyzed, including the classic 2-year impact factor (2YIF), 2YIF without journal self-citations (2YIF*), 5-year impact factor (5YIF), Immediacy (or zero-year impact factor (0YIF)), Impact Factor Inflation (IFI), Self-citation Threshold Approval Rating (STAR), Eigenfactor score, Article Influence, C3PO (Citation Performance Per Paper Online), h-index, Zinfluence, and PI-BETA (Papers Ignored – By Even The Authors). The RAM are analyzed for 10 leading econometrics journals and 4 leading statistics journals. The application to econometrics can be used as a template for other areas in economics, for other scientific disciplines, and as a benchmark for newer journals in a range of disciplines. In addition to evaluating high quality research in leading econometrics journals, the paper also compares econometrics and statistics, alternative RAM, highlights the similarities and differences of the alternative RAM, finds that several RAM capture similar performance characteristics for the leading econometrics and statistics journals, while the new PI-BETA criterion is not highly correlated with any of the other RAM, and hence conveys additional information regarding RAM, highlights major research areas in leading journals in econometrics, and discusses some likely future uses of RAM, and shows that the harmonic mean of 13 RAM provides more robust journal rankings than relying solely on 2YIF.  相似文献

Large firms face a conflict in managing a portfolio of high-risk projects. When an ongoing project is thought to have a low likelihood of success, project team members take risks to improve its chances of success. However, upper-level managers who allocate resources tend to withhold resources from a project with a low likelihood of success in favor of others in the portfolio that look more promising. Because this paucity of resources influences project team members to avoid risk, the total effect of success likelihood on risk taking is conflicted. The influence on risk taking of a project's terminal value—defined as the value that remains in the firm in the event of project failure—is unequivocally positive, because both senior management resource allocation and project team risk-taking propensity are encouraged by terminal value. Thus, firms can override the ambivalent effect of likelihood of success on project decision making by focusing attention on a project's terminal value.  相似文献

学习英文在语法、词汇两方面存在着中英、英英差别。“通过比较、找出差别、加深理解”的学习方法在培养学生的阅读、写作、翻译以及综合运用能力方面起着重要作用。比较研究法作为一种学习和思维方法,不仅适用于高校外语教学,有利于提高学生解决问题的能力,同时在第二外语习得以及跨文化交流中也同样具有重要意义。  相似文献
