Exposure by Assessment: Effects of Daily AMQ-Based EMA of an Intrusive Trauma Memory in PTSD

Sponsor

Tel Aviv University

Enrollment

50 participants

Start Date

Jun 14, 2026

Study Type

INTERVENTIONAL

Conditions

PTSD

Summary

Intrusive re-experiencing is a hallmak of PTSD. We apply ecological momentary assessment (EMA) of participant's trauma memory (active group) vs. EMA of a neutral memory (control group) to test whether the active intervention can reduce intrucive severity in PTSD and PTSD severity in general.

Eligibility

Min Age: 18 YearsMax Age: 70 Years

Inclusion Criteria1

Adults aged 18-70 with symptoms of posttraumatic stress disorder and intrusive symptoms.

Psychotic disorder or bipolar disorder; heavy use of drugs or alcohol; prominent personality disorders; significant risk of harm to self or others; current trauma-focused treatment; reporting intrusions as thoughts only rather than as memories.

Interventions

OTHERAMQ-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.

OTHERAMQ-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.
