What this trial studies

This clinical trial investigates the effectiveness of a brief digital intervention aimed at reducing intrusive memories in women who are part of the SAGA cohort. Participants will be randomly assigned to one of three groups: a self-guided imagery-competing task, a self-guided psychoeducation task, or treatment as usual. The study will assess the number of intrusive memories experienced by participants over a five-week period, controlling for baseline memory frequency. The research will utilize both frequentist and Bayesian statistical analyses to evaluate the outcomes.

Who should consider this trial

Good fit: Ideal candidates are Icelandic women aged 18 and above who have experienced three or more intrusive memories in the past week and are part of the SAGA cohort.

Not a fit: Patients who do not experience at least three intrusive memories during the baseline week or are at risk of suicide may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly reduce the frequency of intrusive memories, improving daily functioning and emotional well-being for affected women.

How similar studies have performed: Previous pilot studies have shown that similar cognitive interventions can be effective in reducing intrusive memories, indicating potential for success in this trial.
