ABSTRACT Despite Institutional Review Board concerns about psychological harm arising from research participation, evidence from trauma-questionnaire research suggests that participation is typically well-tolerated by participants. Yet, it is unclear how participant experiences of in-lab trauma simulations align with IRB ethical guidelines. Thus, we compared reactions to a trauma film paradigm with reactions to a positive film task or cognitive tasks. Overall, relative to other conditions, the trauma film was well-tolerated by participants: they generally reported low-to-moderate negative emotions, moderate benefits, and (...) that participation was not worse than everyday stressors. Our results have implications for the research community in designing trauma-based research. (shrink)

Online platforms like Instagram cover potentially distressing imagery with a sensitive-content screen (blurred imagery plus a content warning). Previous research suggests people typically choose to “uncover” and view screened content. In three studies, we investigated whether the presence of screens mitigates the negative emotional impact of viewing content. In Study 1, participants viewed positive and neutral images, and screens (with an option to view the negative images beneath) for a 5-minute period. In Study 2, half the participants saw a grey (...) mask in place of the typical sensitive-content screen. In addition, each image appeared for a fixed period (5 s) and participants had no option to uncover it. Study 3 was like Study 2 except half the participants saw negative images preceded by a sensitive-content screen and half saw negative images without screens. Overall, participants reported a significant increase in state anxiety and negative affect from pre-to post task when they were exposed to sensitive-content screens, whether or not they were also exposed to the negative imagery beneath. Our data suggest sensitive-content screens cause negative responses – state anxiety and negative affect – that do not translate to an emotional benefit when people view negative content. (shrink)

The informed consent process presents challenges for psychological trauma research (e.g. Institutional Review Board [IRB] apprehension). While previous research documents researcher and IRB-member perspectives on these challenges, participant views remain absent. Thus, using a mixed-methods approach, we investigated participant views on consent guidelines in two convenience samples: crowdsourced (N = 268) and undergraduate (N = 265) participants. We also examined whether trauma-exposure influenced participant views. Overall, participants were satisfied with current guidelines, providing minor feedback and ethical reminders for researchers. Moreover, (...) participant views for consent were similar irrespective of trauma-exposure. Our study has implications for IRBs and psychological researchers. (shrink)

Warning research participants and patients about potential risks associated with participation/treatment is a fundamental part of consent. However, such risk warnings might cause negative expectations and subsequent nocebo effects (i.e., negative expectations cause negative outcomes) in participants. Because no existing review documents how past research has quantitatively examined nocebo effects – and negative expectations – arising from consent risk warnings, we conducted a pre-registered scoping review (N = 9). We identified several methodological issues across these studies, which in addition to (...) mixed findings, limit conclusions about whether risk warnings cause nocebo effects. (shrink)
