ABSTRACT

Background:

The current manuscript describes the protocol for a study that examines the daily-level impacts of the Processing of Positive Memories Technique (PPMT) in a trauma-exposed, non-clinical community sample. PPMT is a promising new treatment approach for posttraumatic stress disorder (PTSD); preliminary case series studies have found post-intervention reductions in PTSD symptoms, negative affect, and negative cognitions. However, PPMT’s effects have not been investigated at the daily level.

Objective:

The current study uses a unique research protocol, which combines case series design and daily diary approaches to examine changes in daily affect, daily cognitions, and daily PTSD symptoms pre- and post-PPMT.

Methods:

Participants (n = 70) are currently being recruited from a metroplex in the southwest United States. Following a screening survey, eligible participants complete a pre-intervention baseline survey followed by 21 daily surveys in their natural environments. Then, they receive 4 PPMT weekly sessions. After the conclusion of the PPMT intervention, participants complete a post-intervention outcome survey and 21 daily surveys. To compare daily affect, daily cognitions, and daily PTSD symptoms pre- and post-PPMT, we will use the daily diary reports and conduct multilevel random intercepts and slopes linear regression models.

Results:

Data collection was initiated in March 2022 and is expected to end by June 2024.

Conclusions:

Study findings could clarify whether deficits in positive autobiographical memory processes may also characterize PTSD alongside deficits in traumatic memory processes. Further, PPMT could be an additional therapeutic tool for clinicians to help clients with posttraumatic distress.
