Integration Issues of Qualitative and Quantitative Methods in Psychological Research

The article discusses the integration of qualitative and quantitative methods in psychological research. It is shown that the idea of such integration is embedded in the B.F. Lomov’s systemic paradigm and is in the general trend of modern research related to the Mixed Methods approaches. Examples of the development of the systemic paradigm in scientific and practical research of cognition and communication are given, in particular, concerning the application of the strategy of triangulation and the principles of inductive analysis for the integration of qualitative and quantitative empirical data. The specific possibilities of multiple triangulation and inductive analysis of not only data obtained by qualitative methods, but also quantitative data obtained by instrumental methods are considered. Studies are presented where qualitative (verbal) data are converted into quantitative ones, to which standard statistical procedures are applicable to identify causal links.
