The Lóa Study: a Brief Digital Intervention for Women with Intrusive Memories in the SAGA Cohort
The Lóa Study: a Randomised Control Trial of a Brief Digital Intervention to Support Women Experiencing Intrusive Memories of Traumatic Events During Their Lifespan from the SAGA Cohort
University of Iceland
380 participants

INTERVENTIONAL
Conditions
Summary
Intrusive memories are sensory memories of a traumatic event(s) that spring to mind involuntarily, and can evoke strong emotions and disrupt functioning in daily life. Previous research has indicated that a brief cognitive intervention can prevent the development of intrusive memories as well as reduce the number of intrusive memories of long-standing trauma. Initial pilot work (using case studies and a pilot study, ClinicalTrials.gov identifier: NCT05089058) with women in Iceland indicates that the intervention is acceptable and feasible. This randomised controlled trial will compare 3 arms to investigate if access to a cognitive task - either a brief self-guided imagery-competing task or a brief self-guided psychoeducation and signposting task - versus treatment as usual, can reduce the number of intrusive memories in week 5 (i.e., between-groups comparison), controlling for the number of intrusive memories in the baseline week. The effect on the number of intrusive memories in week 5 (primary outcome), and other symptoms of post-traumatic stress, sleep and cognitive functioning will be tested. This study is funded by the Icelandic Research Fund (11709-0270) and (200095-5601) and The Oak Foundation (OCAY-18-442).
