Exploring healthcare workers' experiences of a simple intervention to reduce their intrusive memories of psychological trauma: an interpretative phenomenological analysis.

ABSTRACTBackground: Many healthcare workers (HCWs) endured psychologically traumatic events at work during the coronavirus disease 2019 (COVID-19) pandemic. For some, these events are re-experienced as unwanted, recurrent, and distressing intrusive memories. Simple psychological support measures are needed to reduce such symptoms of post-traumatic stress in this population. A novel intervention to target intrusive memories, called an imagery-competing task intervention (ICTI), has been developed from the laboratory. The intervention includes a brief memory reminder cue, then a visuospatial task (Tetris® gameplay using mental rotation instructions for approximately 20 min) thought to interfere with the traumatic memory image and reduce its intrusiveness. The intervention has been adapted and evaluated in a randomized controlled trial (RCT) with Swedish HCWs (ClinicalTrials.gov identifier: NCT04460014).Objective: We aimed to explore how HCWs who worked during the COVID-19 pandemic experienced the use of a brief intervention to reduce their intrusive memories of work-related trauma.Method: Interpretative phenomenological analysis was used for in-depth understanding of the lived experiences of HCWs who used the intervention. Seven participants from the RCT were interviewed by an independent researcher without prior knowledge of the intervention. Interviews were conducted via telephone and transcribed verbatim.Results: Four general themes were generated: 'Triggers and troublesome images', 'Five Ws regarding support - what, when, why, by/with who, for whom', 'Receiving it, believing it, and doing it' and 'The intervention - a different kind of help'; the last two included two subthemes each. The results reflect participants' similarities and differences in their lived experiences of intrusive memories, support measures, and intervention impressions and effects.Conclusion: HCWs' experiences of the novel ICTI reflect a promising appraisal of the intervention as a potential help measure for reducing intrusive memories after trauma, and gives us a detailed understanding of HCWs' needs, with suggestions for its adaption for future implementation.Trial registration: ClinicalTrials.gov identifier: NCT04460014.

Many healthcare workers experience images or 'flashbacks' of traumatic experiences from their work during the COVID-19 pandemic.To ensure that individual needs are met, there is a need to tailor and refine current psychological support measures and their use for healthcare workers.The imagery-competing task intervention was perceived as acceptable, indicating its potential utility as a help measure to reduce intrusive memories after trauma.

Using a daily diary for monitoring intrusive memories of trauma: A translational data synthesis study exploring convergent validity.

OBJECTIVE: Intrusive memories are a core feature of posttraumatic stress disorder and have transdiagnostic relevance across mental disorders. Establishing flexible methods to monitor intrusions, including patterns and characteristics, is a key challenge. A daily diary has been developed in experimental settings to provide symptom count data, without the need for retrospective self-report over extended time periods (e.g., 1 week, 1 month). We conducted an exploratory, pre-registered data synthesis investigating convergence between the diary and questionnaire measures of intrusive symptoms long used in clinical practice (Impact of Event Scale, IES, and revised version, IES-R, Intrusion subscale). RESULTS: Utilising datasets using the daily diary from 11 studies (4 real-world trauma studies, seven analogue trauma studies; total N = 578), we found significant positive associations between the diary and IES/IES-R Intrusion subscale. Exploratory analyses indicated that the magnitude of this association was stronger for the IES (vs. the IES-R), and in individuals with real-world (vs. analogue) trauma. CONCLUSION: This study provides first evidence of convergent validity of a daily diary for monitoring intrusions with a widely used questionnaire. A diary may be a more flexible methodology to obtain information about intrusions (frequency, characteristics, triggers, content), relative to questionnaires which rely on retrospective reporting of symptoms over extended timeframes. We discuss potential benefits of daily monitoring of intrusions in clinical and research contexts.
