Social scientific investigations on coping with illness, on the relevance of life events or social support for psychic disorders are concerned with a variety of constructs with interdependent structures. Hypotheses in interrelationships are set up and tested on the construct level. A problem quite often overlooked here is that almost all constructs overlap to a considerable extent both with regard to their content as well as operationally, i.e. they are confounded. Interrelations of constructs which are strongly content-related or operationally confounded are thus in danger of demonstrating artificial results. Data from an extensive epidemiological research project on the incidence and prevalence of psychic disorders in the general population are used applying structural equation models for latent variables to demonstrate confoundation effects for the constructs personality, social support and state of health. Appropriate control methods are described. The results show that partner support maintains a strong influence on the psychic and physical state of health even confoundation of content has been excluded. Application of this method of content confoundation control is discussed with regard to research on coping life event research etc.
关于应对疾病、生活事件的相关性或社会支持对精神障碍影响的社会科学调查，涉及到各种具有相互依存结构的构想。关于相互关系的假设是在构想层面上建立并进行检验的。这里经常被忽视的一个问题是，几乎所有构想在内容和操作方面都有相当程度的重叠，也就是说它们相互混淆。因此，在内容上高度相关或在操作上相互混淆的构想之间的相互关系，有产生虚假结果的风险。来自一项关于普通人群中精神障碍发病率和患病率的广泛流行病学研究项目的数据，被用于应用潜在变量的结构方程模型，以展示人格、社会支持和健康状况等构想的混淆效应。文中描述了适当的控制方法。结果表明，即使排除了内容混淆，伴侣支持对心理健康和身体健康状况仍有很强的影响。本文还就应对生活事件研究等方面，讨论了这种内容混淆控制方法的应用。
