Ethics of asking trauma-related questions and exposing participants to arousal-inducing stimuli

Abstract

This study examined ethical concerns related to exposing participants with childhood victimization histories to both trauma-specific and non-trauma-specific stimuli. We asked participants questions about childhood victimization experiences and exposed participants to a negatively-arousing experimental condition. Following each of these procedures and at a one-week follow-up session, participants completed a measure designed to asses their reactions to participation. The measure included several questions to assess reactions including questions about distress, benefit, and willingness to participate in the study again. Overall, participants reported low levels of distress and described their participation experience as interesting, enjoyable, and somewhat beneficial. Participants also indicated that they would be willing to participate in the study again with the knowledge of what participation was actually like. Participants with childhood trauma histories and PTSD symptoms reported more distress during the childhood maltreatment screening compared to other participants. However, the level of distress they experienced was mild and transitory. Our findings add to the emerging data indicating that individuals find their participation in trauma-related research to be a positive experience overall, rather than a harmful one.
