It is not necessary to obtain an ethical advice from one of the advice committees within the University of Antwerp for every type of research within the Social Sciences and Humanities that involves live participants. In general, the following rule has to be applied: if there is a possible (physical, psychological or social) risk for the participants, an advice has to be obtained. These stress factors might also relate to the privacy of data or damage to the public or personal reputation of the people involved. It is also possible that the agency funding your study explicitly asks to attach an ethical advice.
Attached you can find a couple of guidelines that might help you to determine whether your research requires an ethical advice or not. Whether a study has ethical consequences or not, can never be fully determined by the researcher. In case of doubt, it is always best to contact the Ethics Committee for the Social Sciences and Humanities of the university.
At this time the Ethics Committee for the Social Sciences and Humanities has insufficient capacity to evaluate master studies as well. The commission currently focusses on applications beginning at the level of a doctorate.
