Dynamics in the Development of Organizational Stress

该项目旨在接替一个已经在进行的项目，它应该是一系列项目的一部分，这些项目将继续这一研究流。已经在进行的DFG项目(DO 763/9-1)涉及组织压力小组研究的荟萃分析。总的来说，该系列项目将继续发展小组研究的荟萃分析的方法学基础，并相继提供对主要研究的更详细的荟萃分析。目前的建议有四个主要目的。首先，它应该使我们能够继续对现有的关于组织压力的小组研究进行荟萃分析。被录用的博士生(之前批准的两年制项目)应该完成她的博士论文，然后作为博士后继续公布结果。第二，后续的荟萃分析应该扩展到包括从日记研究中获得的数据。这使我们能够研究测量间隔之间的时间间隔对组织压力源在比迄今可用的时间间隔范围更广的范围内的影响。此外，这将产生最佳间隔时间的证据，这对未来小组研究的设计将是重要的。第三，该提案应使我们能够进行重复测量研究，这可以由已授予研究生院的博士生进行。在这些研究中，我们将调查使用不同时间间隔的研究是否可以相互替代。例如，这解决了一个问题，即使用1周间隔的研究结果是否反映了使用1年间隔的研究的相同过程。从实质性的角度来看，我们将关注自尊对压力来源的威胁，例如分配不合法的任务。此外，我们已经开发了一种新型的Meta分析，它明确地解释了不同的初级研究时间间隔(CoTiMA)。这项工作应以方便用户的方式完成并编制程序。数学基础是众所周知的，但将其转换为统计程序以允许测试结构方程模型最近才刚刚完成，并且只有使用特定的包(R中的OpenMx)才能实现。例如，我们的第一个CoTiMA仍然需要几千行代码。通过编写一个更友好的界面，我们打算让CoTiMA对许多研究人员有用，并促进它在社区中的推广。

The project is intended to succeed an already ongoing project, and it is supposed to be part of a series of projects that will continue this stream of research. The already ongoing DFG-project (DO 763/9-1) deals with the meta-analysis of panel studies of organizational stress. In general, the series of projects will continue developing the methodological foundations of meta-analyses of panel studies as well as providing successively more detailed meta-analyses of primary studies. The present proposal has four major aims. First, it should enable us to continue the meta-analysis of existing panels studies on organizational stress. The hired doctoral student (of the previously granted 2 year project) should finalize her doctoral thesis and then continue pub-lishing results as a post doc.Second, subsequent meta-analyses should be extended to include data obtained in diary studies. This enables us investigating the impact of time intervals between measurement occa-sion on effect sizes of organizational stressors across a much wider range of time intervals than those available so far. Among other things, this will yield evidence of optimal time inter-vals, which would be important for the design of future panels studies.Third, the proposal should enable us conducting repeated measurement studies, which could be carried out by doctoral students of an already granted graduate school. In these stud-ies we will investigate if studies using different time intervals could serve a substitutes for each other. This addresses, for example, the question if results of a study using a 1-week in-terval reflect the same processes as studies using a 1-year interval. From a substantive point of view we will focus on self-esteem threating stressors such as the assignment of illegitimate tasks.Forth, we already developed a new type of meta-analysis that explicitly accounts for dif-ferent time intervals of primary studies (CoTiMA). This should be completed and pro-grammed in a user-friendly fashion. The mathematical foundations are well-know for long, but the translation into statistical programs that allow for testing structural equation models has just been done recently and is only possible with using a particular package (OpenMx in R). Our first CoTiMA, for instance, still required a couple of thousand lines of code. By means of programming a user-friendlier interface we intend to make CoTiMA usable for many researchers and facilitate spreading it in the community.
