RESUMEN
Disgust is a common emotional response to trauma but is studied less frequently than fear or other negative emotions. In laboratory settings, individuals with a history of sexual assault report more disgust following exposure to trauma reminders than those exposed to other trauma types, and people with more severe posttraumatic stress disorder (PTSD) symptoms typically report more disgust than those with lower symptom levels. It remains unknown whether this association is also present in ecological contexts and if these associations vary by trauma reminder type. The present sample included 80 trauma-exposed community members (PTSD: n = 39, no PTSD: n = 41) who completed up to 17 prompts per day for 3 days (2,158 total completed surveys). Multilevel models indicated that trauma reminders were associated with increased feelings of disgust, B = 0.16, SE = 0.06, p < .001, which was consistent across trauma reminder types, p < .001-p = .001. PTSD symptom severity moderated the association between trauma reminders and disgust such that it was stronger for participants with higher CAPS-5 scores, B = 0.02, SE = 0.01, p = .011. All trauma reminder types demonstrated the same pattern of moderation, ps = .003-.022, except flashbacks, p = .070. Trauma type was not a significant moderator of any trauma reminder type, ps = .193-.929. These findings suggest that trauma reminders encountered in daily life are associated with feelings of disgust. The results underscore the importance of exploring disgust as a trauma-related emotional experience among trauma survivors.
RESUMEN
INTRODUCTION: Trauma exposure is often assessed using checklists such as the Life Events Checklist for DSM-5 (LEC-5; Weathers et al., 2013b). When participants endorse multiple events, respondents are asked to identify a single, worst event (i.e., index event). Recent work indicates that the "worst event" method leads to a concerning number of false negatives. The purpose of the current study was to replicate previous findings of false negatives and extend them by examining characteristics associated with false negatives, such as trauma type, means of exposure, recency of trauma, and posttraumatic stress disorder (PTSD) symptom severity. METHOD: Adults (n = 476) provided data on trauma history assessed using a revised version of the LEC-5 that asked participants to provide follow-up information for each traumatic event endorsed. Participants also provided demographic data and completed the PTSD Checklist for DSM-5. Results: Two hundred thirty-four participants (49.16%) reported a worst event that met the DSM-5 definition of Criterion A trauma ("primary Criterion A" group). However, of the 242 participants who did not, 138 participants (57.02%, or 28.99% of the total sample) reported a secondary event that did meet Criterion A ("secondary Criterion A" group). The secondary Criterion A group most commonly reported serious life-threatening illnesses/injuries and "other" stressful life experiences as their index trauma that did not fulfill Criterion A. Participants in the primary and secondary Criterion A groups reported similar levels of PTSD symptoms. No differences were observed in means of exposure and recency of index trauma between the Criterion A groups. DISCUSSION: Findings raise questions regarding the efficiency and accuracy of the worst event method to determine trauma exposure status via self-report. Researchers should consider alternative methods for assessing trauma exposure rather than relying on the worst event scoring method. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
