Posttraumatic stress and hazardous alcohol use in trauma-exposed young adults: indirect effects of self-disgust

Still in there-citizens' well-being and PTSD after Seoul Halloween crowd crush in Korea: a cross-sectional study

The October 29, 2022, Seoul Halloween Crowd Crush (SHCC) caused the loss of 159 lives, making it the deadliest global mass-gathering disaster between 2018 and 2022. Despite the fact that years have passed since the incident, there remains a significant gap in research addressing the mental health of citizens to evaluate their recovery progress. Therefore, in this study, a survey was conducted to assess citizens' anxiety, depression, post-traumatic stress disorder (PTSD), and well-being after the SHCC. The data were analyzed using t-tests, analysis of variance (ANOVA), correlations, a Kruskal-Wallis test, and post hoc tests. The citizens' well-being differed significantly by victimization status, with direct victims showing languishing well-being (p = .036). PTSD severity level was higher in victims and direct witnesses (p < .001). Victims and direct witnesses exhibited worse outcomes in subjective, social, and psychological well-being as well as in PTSD (p < .001). Well-being exhibited a significant negative correlation with PTSD (r =  - .247, p < .001). The results of the analysis suggest the SHCC's psychological impact has endured not only for victims and direct witnesses but also for media-exposed citizens. Offering continuous psychological support and fostering positive self-perceptions and social interactions are crucial for their recovery and well-being enhancement.

Is self-disgust an implicit or explicit emotional schema?

Self-disgust, a negative self-conscious emotional schema that is associated with mental health difficulties in both clinical and non-clinical populations, is typically assessed with self-reported measures that target physical and behavioural aspects of the self. The aim of the present research was to develop and validate a novel implicit self-disgust measure (ISDM) using an Implicit Association Task (IAT) paradigm, across three studies. Study 1 developed a list of disgust-related and positive words that were rated for emotional valence and arousal and informed the content of the ISDM. Study 2 developed and examined the ISDM using the single-target IAT in a non-clinical population and showed that scores in the ISDM were significantly associated with self-reported self-disgust. Study 3 partly replicated the findings of Study 2 among participants with trauma-related experiences and following a mood induction paradigm, showing a significant association between the ISDM and the physical aspect of self-reported self-disgust. These findings are significant because they have implications about the automaticity of self-disgust in people with traumatic experiences which can further inform clinical practice and interventions targeting self-disgust.

Trauma reminders and disgust: The roles of posttraumatic stress disorder symptom severity, trauma type, and reminder type

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.

Substance Use Frequency Relates to Suicidal Ideation Through Perceived Burdensomeness and to Suicide Attempts Through Capability for Suicide

BACKGROUND

Although substance use has been linked to both suicidal ideation and suicide attempts, the factors underlying these relations remain unclear. The Interpersonal-Psychological Theory of Suicide (ITS) provides a framework for understanding how substance use may increase suicide risk. The purpose of the current study was to examine if frequency of substance use is indirectly related to suicidal ideation and suicide attempts through core ITS variables (i.e., burdensomeness, thwarted belongingness, and suicide capability).

METHODS

An online sample of Mechanical Turk workers (N = 365) completed measures assessing substance use frequency, burdensomeness, thwarted belongingness, suicide capability, suicidal ideation, and suicide attempts.

RESULTS

After controlling for relevant clinical and demographic covariates, substance use frequency was indirectly related to suicidal ideation through burdensomeness but not thwarted belongingness. Substance use frequency was indirectly related to suicide attempts through suicide capability only.

LIMITATIONS

The cross-sectional design precludes conclusions about the precise nature and direction of the relations examined. The use of a community sample limits generalizability to more severe substance using samples.

CONCLUSIONS

Results highlight the relevance of distinct ITS factors in the relation between substance use frequency and both suicidal ideation and suicide attempts. Results may inform specific targets for novel interventions aimed at reducing suicide risk among substance-using individuals.HighlightsSubstance use frequency was indirectly related to SI through burdensomeness.Substance use frequency was not indirectly related to SI through thwarted belongingness.Substance use frequency was indirectly related to SA only through suicide capability.
