本文着重于多方法方法的机会和优势，广泛称为方法三角测量，其中不同的研究方法应用于一个研究对象。在实践中，这可以通过将有关生命过程的定量结构数据与定性方法收集的生命过程数据的解释和评价相结合来实现。这种方法进行审查，以阐明的问题，研究结果往往显示不同的现象，而不是一个现象的不同方面。对调查结果之间的关系（一致、互补或分歧）的讨论表明，在这种情况下，多方法的方法仍然可以用来提高有效性和检验假设。此外，它的特殊优势是对现有模型和理论的经验性修改，以及新解释的发展。
The essay focuses on the opportunities and strengths of a multi-method approach, widely called methodological triangulation, in which different investigative methods are applied to one research object. In practice, this can be realized with the coupling of quantitative structural data concerning the life course and the interpretation and evaluation of life course data collected with qualitative methods. This approach is examined in order to shed light on the problem that research findings often show different phenomena and not the different aspects of one phenomenon. The discussion of the relationships of the findings to one another (congruent, complementary or divergent) shows that in this context a multi-method approach can nevertheless be used to increase validity and to test hypotheses. Further, its particular strengths are the empirically induced modification of existing models and theories, as well as the development of new explanations.
