Abstract
The article discusses different theoretical perspectives that are relevant in analysing long-term tranquillizer use. The theories mentioned are, e.g., behavioral theory models, cognitive models, humanistic and existential models, transpersonal identity models, psychodynamic reasoning, sociological and anthropological perspectives. A multidimensional model focusing on the connection between identity structure and long-term tranquillizer use is presented. The article argues for the use of mixed methodological strategies, e.g., quantitative and qualitative methods. The implications of the “actor–spectator paradox” for the analysis of data are also discussed in some detail. [Translations are provided in the International Abstracts Section of this issue.]
