6) Referral to third parties in case of psychological problems
It is not uncommon that manipulations potentially have a negative (emotional) aftereffect on participants, or trigger certain behaviours, intended or not by the researcher. If this is possible, then professional help must be offered, but it is important that the responsible researcher is always informed. Even if both a professional organisation and the address of the responsible researcher are given in the Debriefing, there is a chance that a participant will only contact the professional organisation, and then the researcher would remain uninformed of the unwanted aftereffect. For this reason, in principle only the name of the responsible researcher, or someone very close, should be provided as contact in case of psychological problems. They can then refer to professional support, if needed.
