The diploma thesis deals with randomized response techniques and their use in the self- report study of crime and delinquency. Even though the techniques were designed as a response to measurement problems that are encountered also in self-report studies of criminal and delinquent behaviour, they have so far been employed rarely in this context. The aim of the thesis is therefore to explore the potential as well as limits of randomized response techniques for this field of study from a substantial, methodological, practical and technical point of view. The first part tries to determine to what extent self-report studies of crime and delinquency can benefit from the basic asset of randomized response techniques, that is possibility of reducing bias stemming from respondents unwillingness to give honest answers to sensitive questions. We arrive to the conclusion that the self-report study of crime and delinquency could make use of the techniques from a substantial point of view. We point out the fact, however, that within self-report studies there are a lot of sources of measurement error from which only few may be addressed by the techniques. The second part describes randomized response techniques that have not been introduced in detail so far in the Czech context. It focuses not only on the basic...
