Qualitative study: sex workers
Martin Dawes explains a study that considers police violence and sexual risk in Serbia
The topic of this paper is disturbing. You might argue that we should look at a paper clinically and dispassionately, but that is not the only way. As doctors it is desirable that we show empathy and understanding for patients. A paper such as this should be read for its academic value, but also we should acknowledge the disturbing emotional content that it contains and the empathy it may engender for the participants of the research.
We should first identify whether this study is voyeurism or whether the authors are trying to answer a question, and see why they think this question is important. This information is usually found in the introduction. This paper's introduction gives a clear description of the problem of violence against sex workers. The authors do not describe a specific question, but you can infer that they wanted to know more about violence against sex workers.
