There are pre-implementation materials to measure organizational or provider readiness for Attachment and Biobehavioral Catch-up (ABC) as listed below:

A half-hour screening is used to predict which potential coaches (i.e., home visitors) are likely to be most successful. This screening can be conducted remotely through video conferencing with potential coaches. After the screening, program staff informs the parent coach as to their suitability for training. This step is conducted before training.

There is formal support available for implementation of Attachment and Biobehavioral Catch-up (ABC) as listed below:

Supervision is conducted for one year via video conferencing using Zoom (HIPAA-compliant video conference software that the program provides). Parent coach trainees have 2 supervision meetings per week, General Clinical Supervision and "In the Moment Commenting" Supervision:

• General Clinical supervision is 1-hour per week group supervision conducted in groups of 2 or 3, with an expert-level supervisor. Supervision includes video review each week.
• "In the Moment Commenting" supervision is a 30-minute session per week conducted by staff members at the University of Delaware. A 5-minute segment from the parent coach's case is assigned to the parent coach and staff member for coding prior to the supervision session. The supervision is directed at enhancing coding reliability (so that parent coaches will learn to identify triggers for comments and components of comments) and at enhancing comment quality and frequency.

After a year of supervision, parent coaches' adherence and fidelity are evaluated for certification. If they pass, coaches are certified for 2 years, after which time adherence and fidelity are reevaluated.

There are fidelity measures for Attachment and Biobehavioral Catch-up (ABC) as listed below:

Parent coaches are reviewed for both their adherence and their fidelity to the model. Parent coaches are measured on their adherence to manual content and general clinical issues. For treatment adherence, there is a short list of specific issues from each session that are to be covered from manual content. For treatment fidelity, a parent coach's frequency and quality level of "In the Moment" commenting is monitored and tracked each week in addition to a qualitative review.

There are implementation guides or manuals for Attachment and Biobehavioral Catch-up (ABC) as listed below:

Two manuals have been developed for ABC implementation:

• The first manual includes the content of the intervention, describing in detail what material should be covered in each of the 10 sessions. Content is provided with example language that parent coaches may use with the parent. The manual also includes lists of materials needed for each session as well as a summary of the critical adherence items for each session.
• The second manual details procedures and rules for coding "In the Moment" commenting. The manual is designed to help coaches better understand the targets for commenting as well as how to code selected segments on their own sessions.

Implementation materials are supplemental to the intensive supervision provided across a year of training.

Research has not been conducted on how to implement Attachment and Biobehavioral Catch-up (ABC).
