Summary

This single case series feasibility study is designed to investigate the feasibility of remote recruitment and delivery of a brief visuospatial interference intervention for decreasing the number of intrusive memories of trauma among trauma-exposed women in Iceland. The current study is an extension on two studies already preregistered (NCT04209283 and NCT04342416) that included some aspects of in-person recruitment and/or intervention delivery (rather than fully remote as we aim for here). The intervention is a simple cognitive task (a memory cue followed by playing the computer game "Tetris") with accompanying information. A within-subjects multiple baseline AB design is used, in that the length of baseline ('A'; no intervention) and intervention ('B') phases vary within-subjects across individual intrusive trauma memories. Participants will aim to complete at least one week of the baseline ('A') phase followed by at least two intervention sessions with a researcher remotely (via telephone or secure video platform). Intervention sessions comprise the simple cognitive task alongside accompanying information presented in the form of brief animated videos (e.g., explaining the target symptom). Participants are instructed that they may continue using the technique self-guided in subsequent weeks, and they may opt for additional intervention sessions with remote researcher support (maximum 6 intervention sessions). Participants will be asked to monitor the occurrence of intrusive memories of trauma in a daily diary. It is predicted that participants will report fewer total intrusive memories in the fifth week after the second intervention session (primary outcome) compared to in the first baseline week. The investigators will also explore whether the frequency of targeted intrusive memories is going to decrease relative to non-targeted intrusive memories. Furthermore, the investigators will explore whether having fewer intrusive memories is related to functioning and/or PTSD, depressive or anxiety symptoms.

Conditions

Interventions

BEHAVIORAL

Visuospatial Interference

Two remote intervention sessions with a researcher including a simple cognitive task (a memory cue and 25 minutes of Tetris game play with mental rotation) alongside accompanying information. Participants are instructed that they may continue using the technique self-guided after the first intervention session, and they may opt for additional intervention sessions with remote researcher support (maximum 6 intervention sessions).
