Telehealth delivery of modified attachment and biobehavioral catch-up: feasibility, acceptability, and lessons learned.

The COVID-19 pandemic necessitated dramatic shifts in the delivery and evaluation of attachment-based home-visiting services. The pandemic disrupted a pilot randomized clinical trial of modified Attachment and Biobehavioral Catch-Up (mABC), an attachment-based intervention adapted for pregnant and peripartum mothers with opioid use disorders. We transitioned from in-person to telehealth delivery of mABC and modified Developmental Education for Families, an active comparison intervention targeting healthy development. Of 40 mothers then enrolled in study interventions, 30 participated in telehealth, completing an average of 4.7 remote sessions each (SD = 3.0; range = 1-11). Following the transition to telehealth, 52.5% of randomized cases and 65.6% of mothers maintaining custody completed study interventions, comparable to pre-pandemic rates. Overall, telehealth delivery was feasible and acceptable, and mABC parents coaches' ability to observe and comment on attachment-relevant parenting behaviors was preserved. Two mABC case studies are presented and lessons learned for future telehealth implementation of attachment-based interventions are discussed.    .
