简要总结
The current study will examine daily-level impacts of a technique addressing positive memory retrieval on thoughts, feelings, and health among individuals with trauma experiences.
详细描述
Post-traumatic stress disorder (PTSD) is primarily a memory encoding- and retrieval-based disorder. If untreated, there are significant physical, psychological, social, and economic impacts for an individual, their families, and the society broadly. Research demonstrates that positive memory processes contribute to the etiology and maintenance of PTSD symptoms. Indeed, difficulties in retrieving and discussing positive memories are amplified among individuals with PTSD. Further, interventions capitalizing on (positive) memory retrieval have been linked to enhanced psychological well-being.
Considering this literature, the Processing of Positive Memories Technique (PPMT) was developed as a promising new treatment approach for posttraumatic stress disorder (PTSD), which involves detailed narration and processing of specific positive autobiographical memories. This study uses an innovative research protocol that combines case-series design and daily diary approaches to the effects of PPMT on daily affect, daily cognitions, and daily PTSD symptoms. It is hypothesized that at the daily level, in comparison to their an individual's pre-PPMT levels, following the PPMT intervention, participants will report (1) a lower count of endorsed daily PTSD symptoms, (2) increases in daily positive affect and decreases in daily negative affect, (3) increases in positive affect reactivity to daily positive events, and (4) decreases in daily posttrauma cognitions.

结局指标
主要结局
Daily negative and positive affect levels
时间窗: Each day for 21 days prior to and after the intervention and each survey references the past 24 hours
Daily Positive and Negative Affect are assessed by rating the extent of four positive (excited, cheerful, satisfied, relaxed) and six negative (stressed, irritated, anxious, sad, hopeless, insecure) emotions. This is adapted from the 20-item Positive and Negative Affect Scale. The total positive affect subscale score can range from 1 to 20, with higher scores reflecting more positive affect levels. The total negative affect subscale score can range from 1 to 30, with higher scores reflecting more negative affect.
Daily positive events
时间窗: Each day for 21 days prior to and after the intervention and each survey references the past 24 hours
Daily positive events is measured by 1 item which asked participants to think about the most positive event of the day and rate how pleasant it was. The score can range from 1 to 4, with higher scores reflecting that the event was more pleasant.
Daily posttrauma cognitions
时间窗: Each day for 21 days prior to and after the intervention and each survey references the past 24 hours
A 9-item brief version of the Posttraumatic Cognitions Inventory (PTCI-9) will measure trauma-related thoughts/beliefs with the time frame modified to 'in the last 24 hours.' The total raw score can range from 1 to 63, with higher scores reflecting endorsement of more negative posttrauma cognitions.
Daily PTSD symptoms
时间窗: Each day for 21 days prior to and after the intervention and each survey references the past 24 hours
Daily-life version of the Primary Care-PTSD-5 screen (PC-PTSD-5) will assess daily PTSD symptoms with the time frame modified to 'in the last 24 hours.' The total score can range from 0 to 5, with higher scores reflecting endorsement of more PTSD symptoms.
Number of retrieved positive memories
时间窗: 1 week after intervention sessions
AMT assesses the number of retrieved positive memories by using five cue words followed by a prompt to recall a personally meaningful and specific memory of an event that took place within any 24-hour period. The total score could range from 0 to 5, with higher scores indicating more number of retrieved positive memories.
次要结局
- Positive Emotion Dysregulation(At each of the 4 weekly intervention sessions and each survey references the past week)
- PTSD symptom severity(At each of the 4 weekly intervention sessions and each survey references the past week)
