Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of intrusive memories of traumatic event(s)
Time Frame: Week 0 and Week 1
|
Number of intrusive memories of traumatic event(s) recorded by participants in a brief diary daily (morning, afternoon, evening and night) for 7 days.
|
Week 0 and Week 1
|
Intrusion questionnaire - frequency item
Time Frame: Baseline (Day 1), Week 1 and 5 and 1, 3, and 6 month follow-up
|
A single item measuring the frequency of intrusive/unwanted memories of the traumatic event(s) in the previous week on a 7-point scale (from "never" to "many times a day", with a follow-up question to specify the number if necessary) that will be used as a convergent measure for medical hospital staff who may face time constraints completing the diary.
|
Baseline (Day 1), Week 1 and 5 and 1, 3, and 6 month follow-up
|
Intrusion questionnaire - characteristics
Time Frame: Baseline (Day 1), One week and 1, 3, and 6 month follow-up
|
5 self-rated items measuring the characteristics of intrusive/unwanted memories in the previous week. The level of distress, nowness, reliving, disconnectedness and whether different triggers are associated with the intrusive/unwanted memories of the traumatic event(s) are measured on a 101-point scale (from 0 to 100). Higher scores indicate more intrusive/unwanted memories, higher levels of distress/nowness/reliving/disconnectedness and a greater number of different triggers. |
Baseline (Day 1), One week and 1, 3, and 6 month follow-up
|
Impact of Event Scale - Revised (IES-R): Degree of subjective distress of post-trauma intrusion and avoidance symptoms
Time Frame: Baseline (Day 1), One week and 1, 3, and 6 month follow-up
|
Self-report measure that assesses subjective distress after a traumatic event (with reference to study event[s]) in the last week.
Here we include the intrusion subscale (8 items) and the avoidance subscale (8 items).
Items are rated on a 5-point scale ranging from 0 ("not at all") to 4 ("extremely").
Subscale scores are calculated for the Intrusion or Avoidance items summed (ranging from 0 to 32 each).
Higher scores indicate worse outcome.
|
Baseline (Day 1), One week and 1, 3, and 6 month follow-up
|
Posttraumatic Stress Disorder Checklist 5 (PCL-5) short version
Time Frame: Baseline (Day 1), One week and 1, 3, and 6 month follow-up
|
The PCL-5 short version is an 8-item self-report measure that assesses current symptoms of post-traumatic stress disorder in the last month [Baseline (Day 1), 1, 3, and 6 month follow-up] and in the last week (One week).
Items are rated on a 5-point scale ranging from 0 ("not at all") to 4 ("extremely").
The PCL-5 short version yields a total symptom severity score which ranges from 0 to 32.
Subscale symptom severity scores for DSM-5 symptom cluster B - intrusion symptoms (items 1-2), cluster C - avoidance (items 3-4), cluster D - negative alterations in cognitions and mood (items 5-6), and cluster E - alterations in arousal and reactivity (items 7-8).
Higher scores indicate worse severity.
