Quantitative empirical social research, especially in the form of standardized interviews, represents the majority of sociological research. However, such studies are also often criticized for constructing results that are rather the outcome of methodological artifacts in surveys and questionnaires than of actual presence in the population. At the same time there is a wide variety of literature that deals with the methodological guidelines in surveys. This thesis is a critical examination of the methods of the ISSP Environment Module. The main focus is primarily on the development and construction of the questionnaires, used in all three studies, as well as their changes over the years. In this light, the data of the Austrian surveys from the years 1994/1995, 2001 and 2010 have been compared to the results of similar studies. The calculations were carried out according to Hadler / Haller (2011). There is only a very small relationship between environmental awareness and action to be found. In the main part of the work, the survey instruments used by the ISSP have been analyzed in more detail, contextual to methodological guidelines, and discussed in addition to the distributions of some items. The measuring instruments showed a variety of problems that are also discussed in the literature. Besides unclear wording of questions and multidimensionality, there were also identified suggestive formulations and strong evidence of halo effects as well as tendencies to socially desirable answers and other response sets. One point of criticism concerns the extensive changes in the questionnaires of the three surveys which make a long-term comparison of the data difficult. As a result, there are some important indices consisting of only two items, which are also used by Hadler / Haller. Generally speaking, and more specifically considering the scope of the ISSP studies, this is very little.
