Using a Visuospatial Interference Intervention to Reduce Intrusive Memories Among Trauma Exposed Women
연구 개요
상세 설명
Participants will attend 3-8 sessions with the researcher. In session one, the intrusive memories will be logged for monitoring their frequency in a daily diary for the following weeks. Baseline assessment questionnaires will also administered. In the second session, a memory will be selected and targeted with the intervention (memory reminder followed by 25 min gameplay with mental rotation) followed by monitoring the frequency of both the targeted and non-targeted intrusive memories. Participants will also complete self-rated questions concerning the impact of their intrusive memories. The intervention session will be repeated for other intrusive memories (maximum 6 intervention sessions). In the last intervention session, participants will be asked to complete questionnaires and self-rated questions assessing the impact of their intrusive memories. Participants will be asked to complete measures at 1 month follow-up and at 3 month follow-up. In the 1 month follow-up, participants complete questionnaires and monitor the frequency of intrusive memories for one week in the daily diary.
The previous version of the CTR incorrectly stated that at the 3 month time point the measure of intrusions will be: 'Questions about the frequency of intrusive memories for the past day/week (for each intrusive memory, to be tallied to arrive at a mean frequency for the memories for the previous day and for the week)'. We changed this measure at the study start to using the same diary as we used for the earlier time points (i.e., daily diary with the same level of detail as the ones used at e.g. at 1 month), but failed to update this in the CTR. The measure has been updated retrospectively in the CTR for this timepoint, and should be interpreted with caution accordingly.

실험적: Trauma exposed women
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: 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.

Change in the number of intrusive memories of trauma
기간: Baseline week 1; Intervention week 1-6 and 1 month follow-up
|
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.
|
Baseline week 1; Intervention week 1-6 and 1 month follow-up
|
|
Change in the number of intrusive memories of trauma from baseline to 3 month follow up
기간: Baseline week 1; 3 month follow-up
|
Number of intrusive memories of traumatic event recorded by participants in a diary daily (morning, afternoon, evening and night) per week during the baseline phase and during one week at three month follow-up. Note that the way this outcome was measured had been specified incorrectly in the previous versions of this CTR (as using questions about frequency) and was therefore updated retrospectively after the end of data collection to the same diary as the previous time points. |

Self-guided intervention adherence - usage of the gameplay intervention in daily life
기간: Intervention week 2-6
|
How often did you manage to play Tetris after you experienced an intrusive memory?
(11-point scale; 0 = not at all; 10 = every time).

Feasibility and acceptability ratings for using a smartphone game-play intervention
기간: Post intervention up to week 7
|
Feasibility and Acceptability of the intervention assessed with two self-rated items, "Would you recommend playing Tetris to a friend?" and "Do you consider gameplay to be an acceptable way to reduce the daily frequency of intrusive memories?".
Scores could range from 0 - 10 with higher scores indicating greater acceptability/feasibility.
|

Feasibility and acceptability - open ended questions
기간: Post intervention up to week 7

Two open-ended questions: 1. "How did you feel about playing Tetris after you had an intrusive memory?" 2. "Did you find the intervention helpful?
If yes, how?"
