Brief Summary

This research study is an extension on a study already preregistered NCT04209283 and is designed to investigate the use of a simple cognitive task (a memory cue followed by playing the computer game "Tetris") for decreasing the number of intrusive memories of trauma among trauma-exposed women in Iceland. This is a single case series using a within subject multiple baseline AB design. Participants will aim to complete a no-intervention phase ('A': baseline phase) of one week followed by a one-week intervention phase ('B'), including a one-session intervention with a researcher comprising the simple cognitive task, followed by instructions to continue using the technique self-guided in subsequent weeks. 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 intrusive memories during the intervention phase than during the preceding baseline phase and that 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 has an impact on function and/or PTSD, depressive or anxiety symptoms.

Outcome Measures

Primary Outcomes (1)

• Change in the number of intrusive memories of trauma

  Number of intrusive memories of traumatic event recorded by participants in a diary daily (morning, afternoon, evening and night) for one week during the baseline phase and each week during the intervention phase (week 1-6) and during one week at one month follow-up and three month follow-up.

  Baseline week 1; Intervention week 1-6; 1 month follow-up and 3 month follow-up

Secondary Outcomes (12)

• Self-guided intervention adherence - usage of the gameplay intervention in daily life

  Intervention week 2-6

• Feasibility and acceptability ratings for using a smartphone game-play intervention

  Post intervention up to week 7

• Feasibility and acceptability - open ended questions

  Post intervention up to week 7

• Impact of intrusive memories on concentration, sleep and stress - ratings

  Baseline week 1; Post intervention up to week 7; 1 month follow-up and 3 month follow-up

• Rating of how long intrusive memories disrupted concentration on average

  Baseline week 1; Post intervention up to week 7; 1 month follow-up and 3 month follow-up

Study Arms (1)

Trauma exposed women

EXPERIMENTAL

No Intervention: Baseline phase ('A'): Measurements collected in a daily diary four times a day (morning, afternoon, evening and night) over one week for the primary outcome (occurrence of intrusive memories of trauma). Individual baseline phases will be used as control periods. Experimental: Intervention phase ('B'): A one-session intervention with a researcher including a simple cognitive task (a memory cue and 25 minutes of Tetris game-play with mental rotation) followed by instructions to engage in the task self-guided over the subsequent week. Measurements collected in a daily diary four times a day following the intervention for the primary outcome (occurrence of intrusive memories of trauma). Intervention: Behavioral: Brief cognitive intervention

Behavioral: Visiospatial Interference

Interventions

Visiospatial Interference BEHAVIORAL

Behavioral: Brief cognitive intervention. A one-session intervention with a researcher including a simple cognitive task (a memory cue and 25 minutes of Tetris game play with mental rotation) with instructions to engage in the task self-guided in the subsequent weeks.
