NCT07658157 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 50

No results posted yet for this study

Summary

Intrusive re-experiencing is a hallmark of PTSD. The study applies ecological momentary assessment (EMA) of participants' trauma memories (active group) vs. EMA of a neutral memory (control group) to test whether the active intervention can reduce intrusive symptoms severity and overal PTSD symptom severity in general.

Conditions

Interventions

OTHER

AMQ-based ecological momentary assessment of an intrusive memory

Participants allocated to this intervention will complete daily AMQ-based ecological momentary assessment (EMA) prompts for 10 days, focused on a personally identified intrusive traumatic memory. The target memory will be selected at the beginning of the trial. The EMA prompts will assess phenomenological and emotional characteristics of the memory, including features related to vividness, emotional intensity, nowness/reliving, and intrusiveness. This intervention is intended to examine whether repeated, low-burden assessment of an intrusive traumatic memory by the participant would be associated with changes in PTSD symptom severity.

OTHER

AMQ-based ecological momentary assessment of an emotionally neutral memory

Participants allocated to this intervention will complete daily AMQ-based ecological momentary assessment (EMA) prompts for 10 days, focused on a personally identified neutral, non-intrusive autobiographical memory. The target memory will be selected at the beginning of the trial. The EMA prompts will be otherwise identical to those administered in the intrusive-memory arm and will assess phenomenological and emotional characteristics of the selected memory. This control intervention is intended to distinguish the effects of repeated memory-focused assessment in general from effects specific to repeated assessment of an intrusive traumatic memory.
