Participants' adherence to intervention
Seventy‐two participants gained access to EJDeR. One was excluded shortly after access (severe and enduring mental health difficulty) and 34/71 (47.9%) adhered to the MTD, nearly meeting progression criteria of 50%. The mean number of modules opened was 2.3 (SD 0.9, range, 1–4), parents completed a mean of 1.7 modules (SD 1.3, range, 0–4), and a mean of 2.7 homework sheets (SD 2.8, range, 0–11). Initial assessment sessions were attended by 61/71 (85.9%) and mid‐intervention booster sessions were attended by 44/71 (62.0%).Visual inspection of data indicated differences in adherence rates by first LICBT module started and by gender. A post hoc descriptive analysis was performed. In total, 54/71 (76.1%) started a LICBT module, with 26 starting with BA and 28 with WM. In total, 20/26 (76.9%) starting with BA, and 14/28 (50.0%) starting with WM adhered to the MTD.Of the 71 participants, 25 were fathers, and 46 were mothers. For fathers: 8/25 (32.0%) started with BA and 7/8 (87.5%) adhered to the MTD; 12/25 (48.0%) started with WM, and 5/12 (41.7%) adhered to the MTD.
