Note.
*
Number of Sessions Completed reflects the number of participants in this sample who completed the Self-Referent Encoding Task (SRET) at any follow-up assessment as of the time of these analyses. Project ACE is still underway and retention rates are likely to change as participants continue in the study. At the time of this manuscript, 80% of ACE participants completed at least one follow-up visit, and 72% of the sample is continuing in the study. The average retention rate for this study, based on participants who have completed the SRET at least once at a follow-up visit and are classified as actively continuing in the study, was 64%.
