Viral outbreaks can be experienced as disruptive and can be associated with traumarelated stress symptoms. In the current study, we adjusted the Dutch version of the Impact of Event Scale (IES) to assess traumatic stress symptoms related to the impact of the COVID-19 outbreak. The psychometric properties of this Impact of Event Scale with modifications for COVID-19 (IES-COVID19) were investigated by administering the IES-COVID19 to 380 university students who participated during the early stage of the COVID-19 outbreak, upon invitation via e-mail. Using confirmatory factor analysis, the factor structure of the IES-COVID19 was found to be similar to the original IES, indicating two latent factors: intrusion and avoidance, c 2 (85) = 147.51, CFI = .92, TLI = .90, RMSEA = .044, SRMR = .049. Cronbach's alpha showed acceptable internal consistency of the total IES-COVID19, a = .75. Pearson's correlations of the IES-COVID19 over time were also sufficient, demonstrating adequate test-retest reliability, r = .62. Significant correlations (ranging between .15 and .50) between the IES-COVID19 and symptoms of depression, anxiety, stress, stress-related rumination, as well as negative social interactions, demonstrate adequate convergent validity. Overall, the IES-COVID19 shows to be a valid and reliable measure that can be utilized to investigate traumarelated stress symptoms of intrusion and avoidance related to the short-and long-term impact of the COVID-19 outbreak.
Introduction We all have stories to tell. The stories that prevail in our conversations frequently concern significant past personal experiences and are accordingly based on autobiographical memory retrieval and sharing. This is in line with the social function of autobiographical memory, which embodies the idea that we share memories with others to develop and maintain social relationships. However, the successful fulfilment of this social function is dependent on phenomenological properties of the memory, which are highly inter-individually different. One important individual difference is memory coherence, operationalized as narrative coherence. The objective of this study was to investigate the impact of memory coherence on the social evaluations of listeners. We hypothesized that being incoherent in the sharing of autobiographical memories, would evoke more negative social evaluations from listeners, in comparison to coherently sharing autobiographical memories. Methods In a within-subject experimental study, 96 participants listened to four pre-recorded audio clips in which the speaker narrated about an autobiographical experience, in either a coherent or an incoherent manner. Results Results were in line with our hypotheses. Participants showed more willingness to interact, more instrumental support, more positive feelings, more empathy and more trust towards those narrators who talked in a coherent manner about their autobiographical memories, as compared to those that talked in an incoherent manner. Negative feelings in the listener were evoked when the speaker talked incoherently, but especially when it concerned a positive memory.
Previous research has suggested that sharing autobiographical memories in a coherent manner has a beneficial impact on consequent social reactions of listeners. In this experimental study, we were able to replicate earlier findings by demonstrating that listeners (N = 107) showed significantly more willingness to interact with, more social support towards, and a more positive attitude towards coherent than incoherent narrators. Remarkably, these beneficial effects of coherence were observed only for narratives about positive memories. Results are explained in the light of the relevance of positive memories for the social bonding function of autobiographical memory. Furthermore, earlier work was extended and refined by investigating effects of the individual constituting dimensions of coherence (context, chronology, theme) on social responses. In line with our predictions, the dimensions of chronology and theme were most important in impacting social responses of listeners. Possibly a reduction of the attraction effect due to increased effortful processing and reduced credibility due to insufficient emotional elaboration might explain these results respectively. Furthermore, social responses were worse when narratives were incoherent with regard to more than one dimension, in line with the expected additive effect. Overall, fully incoherent narratives, which had had low scores on context, chronology, and theme, had the most adverse effect on listeners’ social responses. This study adds significantly to the domain of memory and cognition by showing how cognitive psychological research would benefit from extending a merely intrapersonal perspective to include an interpersonal perspective that considers social implications of memory and cognition as well.
Ample evidence suggests that memories enter a labile state upon retrieval, requiring reconsolidation processes in order to be retained. During this period of instability, various interventions can be applied to modify problematic memories. A novel behavioral intervention was designed, aimed at disrupting amygdala-based cognitive processing following the retrieval of a conditioned threat memory, in order to prevent its reconsolidation. We fear-conditioned participants on day 1, and reactivated their memory on day 2. Following reactivation, the reactivation plus emotional working memory task (R + EWMT) group completed an EWMT, while the reactivation only (RO) group served as a no-task control. On day 3, all participants were tested for memory retention, followed by a test for sensitivity to reinstatement. We observed successful acquisition and reactivation in fear-potentiated startle responding, skin conductance responding and US expectancies in both groups. Differential fear responding was fully preserved in the R + EWMT group relative to the RO group at the beginning of retention testing, and both groups were comparably sensitive to reinstatement. Thus, we failed to obtain any evidence that the execution of an EWMT after threat memory reactivation impairs reconsolidation. Further research is indicated to clarify whether threat memory reconsolidation can be disrupted by taxing relevant WM resources.
Prior research has shown that narrative coherence is associated with more positive emotional responses in the face of traumatic or stressful experiences. However, most of these studies only examined narrative coherence after the stressor had already occurred. Given the outbreak of the novel coronavirus disease COVID-19 in March 2020 in Belgium and the presence of data obtained two years before (February 2018), we could use our baseline narrative coherence data to predict emotional well-being and perceived social support in the midst of the pandemic. In a sample of emerging adults (N T1 = 278, N T2 = 198), higher baseline coherence of narratives about positive autobiographical experiences predicted relative increases in emotional well-being during the COVID-19 pandemic. Furthermore, the relation between the coherence of positive narratives and emotional well-being was partially mediated by perceived social support. These findings suggest that narrative coherence could be an enhancement factor for adaptive emotional coping with stressful situations, in part by evoking more supportive social reactions. This study demonstrates the importance of researching cognition (narrative coherence) and emotion (well-being) to shed light on pressing societal matters such as the global COVID-19 pandemic.
