1. Introduction

Version followed: ABC-Infant (10 weekly home sessions, children about 6–24 months) as published by the developers (Mary Dozier and Kristin Bernard, University of Delaware / ABC Parenting Institute) and described on the HomVEE, NCTSN and NHS Scotland programme pages. Where ABC-Early Childhood (formerly ABC-Toddler, 24–48 months) differs, this is marked. The session manual and the commenting coding manual go only to trainees, so they are not drawn on. The Dozier & Bernard (2019) book was seen only as a publisher description. [source: HomVEE ABC-Infant; HomVEE ABC-Early Childhood; NCTSN fact sheet 2021; NCTSN training guidelines; Guilford book page]

Attachment and Biobehavioral Catch-up (ABC) is a short, manualised, home-visiting parent-coaching programme. It is for caregivers (birth, foster, kinship and adoptive) of infants and young children who have faced early adversity: neglect, maltreatment, foster placement, institutional care, homelessness, or parental substance use or mental illness. It draws on attachment theory and the neurobiology of stress. [source: HomVEE ABC-Infant; NCTSN fact sheet 2021]

How change happens: young children rely on caregivers to co-regulate both their behaviour and their stress biology (the HPA axis and cortisol), and early adversity disrupts this. Children who have been hurt often push caregivers away or are hard to soothe, and some caregivers do not find nurturing natural. So ABC changes a few specific caregiver behaviours: nurturing even when the child does not elicit it, following the child's lead with delight, and not being frightening. The main way it does this is the coach's frequent, real-time "in-the-moment" comments on the dyad's own interactions in their own home, backed up by video feedback. [source: Dozier slides, Sweden; Dozier Penn State slides; NHS Scotland EIF]

This is a licensed programme. You may deliver it under the ABC name only after screening, training and supervised certification by the University of Delaware team (see Section 2). [source: NCTSN training guidelines]

2. Framework

Format

  • Delivery: 10 sessions, about 60 minutes each, weekly, one per family. Sessions take place where the family lives: home, shelter or temporary housing. Virtual or hybrid delivery is allowed on family request or when visits are impossible. [source: HomVEE ABC-Infant; NCTSN fact sheet 2021; NCTSN training guidelines]
  • Who attends: the primary caregiver must be able to attend all 10 sessions. Anyone else in the home may join. There is no group version, because the behaviours have to be practised in the family's own setting. [source: NCTSN training guidelines; Social Work Today 2017]
  • Recording: every session is video recorded. The recordings feed in-session playback and fidelity supervision. Equipment: a camera, a laptop, toys, and a webcam for supervision. [source: NCTSN fact sheet 2021; NCTSN training guidelines; ClinicalTrials.gov NCT05096611 protocol]
  • Session ingredients: each session has the same building blocks:
    • manual-guided discussion of that week's target;
    • review of the homework (daily observations);
    • play-based activities in which the parent practises the targets with the child;
    • video feedback, using clips of the parent from earlier sessions and the programme's standard example clips;
    • in-the-moment comments, positive and supportive, running throughout the manualised content. [source: ClinicalTrials.gov NCT05096611 protocol; NCTSN training guidelines]

Session sequence (ABC-Infant)

SessionsFocusGoal
1–2Nurturing careParent gives nurturance when the child is distressed, including when the child does not elicit it or pushes away. The parent learns to reread the child's cues and not respond in kind to rejecting behaviour.
3–4Following the child's lead with delightParent responds to the child's signals in play without taking over, and shows enjoyment of the child.
5–6Noticing the child's signals; recognising and reducing overwhelming or frightening behaviourParent reduces intrusive, harsh or frightening behaviour, such as glaring, rough handling or threats.
7–8"Voices from the past"Parent sees how their own upbringing shapes automatic reactions that get in the way of nurturing or following the lead, and practises overriding them.
9–10ConsolidationEarlier learning is reinforced, the parent practises more, and progress is celebrated.

[source: HomVEE ABC-Infant; NHS Scotland EIF; Social Work Today 2017]

ABC-Early Childhood (24–48 months) differences

  • Sessions 3–4 add avoiding power or control struggles.
  • Sessions 5–6 become calming strategies and staying present, physically and mentally, while the child is dysregulated. The parent acts as co-regulator.
  • Sessions 7–8 cover how the parent's past affects nurturing, calming and following the lead. [source: HomVEE ABC-Early Childhood; NHS Scotland EIF]
  • The NHS Scotland page describes the frightening-behaviour target as running across the toddler version as well. [uncertain]: the toddler manual is not drawn on, so where it is taught there is not confirmed.

Other versions and adaptations

The developers describe adaptations for:

  • high-risk birth parents, including a foster-care diversion programme;
  • foster parents;
  • international adoptive parents;
  • ABC-Newborn (birth to 6 months, with optional prenatal sessions from the third trimester);
  • telehealth;
  • ABC+D, which pairs ABC with 12 CBT-for-depression videos for depressed mothers.

Cultural adaptation may change language, examples and some activities, but only with approval from, or in partnership with, the ABC Parenting Institute. Guidelines for American Indian communities, developed with Dolores Bigfoot, are in progress and have not yet been used at community sites. [source: Guilford book page; HomVEE ABC-Infant; HomVEE ABC-Early Childhood; ClinicalTrials.gov NCT05096611 protocol]

Moving between phases

ABC moves through a fixed weekly sequence. The sources describe no mastery criterion that holds back progress to the next target. [uncertain]: the restricted manual may say otherwise. Coaches keep commenting on all earlier targets in later sessions; the sources describe comments throughout every session on all three targets. [source: NCTSN fact sheet 2021] Two practical rules follow from the format [synthesis]:

  • Treat sessions 1–6 as skill-building and 7–8 as reflective work on the parent's own history.
  • Start 7–8 only after the parent has had several weeks of positive, strength-based comments, so the reflective work rests on a working alliance.

Certification before delivering under the ABC name

  • Screening: a 30–60 minute video interview. It assesses openness to attachment theory, ability to make in-the-moment comments, and agency readiness. No degree or licence is required. [source: HomVEE ABC-Infant; NCTSN training guidelines]
  • Training: 2 days in person, or 3 half-days virtually. The training covers:
    • the research base;
    • all 10 sessions;
    • in-the-moment commenting and its coding.
    Pre-reading is the session manual (content, sample language, materials and critical adherence items for each session) plus the commenting coding manual. [source: NCTSN training guidelines; HomVEE ABC-Infant]
  • Supervised trainee period: weekly, by video conference:
    • 1 hour of group clinical supervision with 2–3 trainees;
    • 30 minutes of individual in-the-moment supervision, for which the trainee and the fidelity supervisor each code a 5-minute segment of the trainee's latest session beforehand.
    Fidelity metrics: percentage of on-target comments, comments per minute, percentage of missed comment opportunities, and a qualitative rating of comment level. Adherence is checked against each session's critical items. [source: NCTSN training guidelines; HomVEE ABC-Infant]
  • Certification: at least three completed cases, then an adherence and fidelity evaluation. Certification lasts 2 years, and recertification is by webinar and quiz.
    • One training slide gives a criterion of roughly one comment per minute with at least one component per comment. [source: Dozier slides, Sweden]
    • [uncertain] Sources disagree on how long the trainee period lasts and what it costs. NCTSN and NHS Scotland describe a one-year supervision period. HomVEE says at least six months (12 months on the combined infant plus early-childhood path). Cost figures vary from $5,000 to $7,000.
    • Check current terms with the ABC Parenting Institute.

3. Guiding principles

  • Nurture even when it is not elicited. When the child pushes away, turns away or seems not to need you, give comfort anyway. Practical meaning: read rejecting behaviour as a protective strategy learned from adversity, not as a real "I don't need you." [source: Dozier Penn State slides; NHS Scotland EIF]
  • Do not respond in kind. Caregivers naturally mirror a child's pushing away or fussiness, and this deepens the problem. Practical meaning: coach the parent to move toward the child when the child moves away. [source: NHS Scotland EIF; Dozier slides, Sweden]
  • Co-regulation of behaviour and biology. The child's stress physiology is shaped by caregiving. Practical meaning: explain each target as helping the child's body, not only their behaviour, learn to settle. [source: Dozier slides, Sweden; Dozier Penn State slides]
  • Following the lead builds self-regulation. Following the lead is close to synchrony but not the same thing. Practical meaning: in play, the parent responds to what the child is doing rather than directing, teaching or taking over. [source: Dozier Penn State slides]
  • Delight. Following the lead is coached together with visible enjoyment of the child, and delight is a coded target of its own. Practical meaning: notice and name smiles, warmth and pleasure in the parent's face and voice. [source: HomVEE ABC-Infant; Haggerty 2015 thesis abstract]
  • Not frightening, not intrusive, not overwhelming. Harsh, frightening or intrusive behaviour undermines regulation and is linked to disorganised attachment. Practical meaning: help the parent spot their own glares, rough handling, threats, looming or teasing, and choose an alternative. [source: Dozier Penn State slides; Social Work Today 2017]
  • Behaviour-specific and narrow. ABC targets a few concrete behaviours rather than general parenting. Practical meaning: keep every comment and discussion tied to a target. Refer out for needs beyond scope, such as housing, substance use or parental mental illness. [source: Social Work Today 2017]
  • Dyadic and in vivo. Change is practised with the child, in the family's own home. Practical meaning: work with what actually happens in the session rather than talking about parenting in the abstract. [source: Social Work Today 2017, quoting Dozier: delivery "in the home so that parents can practice the behaviors"]
  • In-the-moment commenting is the most crucial ingredient. Comment frequency and quality predict parents' gains in sensitivity and following the lead, and their drops in intrusiveness. Practical meaning: aim for frequent, specific, on-target comments, about one a minute. [source: NCTSN fact sheet 2021; Dozier Penn State slides; Dozier slides, Sweden]
  • Positive and strength-based. Comments are "positive and supportive in nature", and video review celebrates successes. Practical meaning: comment far more often on what the parent does well than on what to change. [source: ClinicalTrials.gov NCT05096611 protocol; HomVEE ABC-Infant]
  • Automatic responses can be overridden. Parents' own caregiving histories ("voices from the past") push them toward non-nurturing or controlling responses, and these can be recognised and overridden. Practical meaning: the aim is behaviour change in the moment, not resolving the parent's past. [source: HomVEE ABC-Infant; Social Work Today 2017]
  • Cultural humility. Sessions include discussion of the personal and cultural experiences that shape parenting. Practical meaning: explore the family's own beliefs about comfort, play and discipline. Adapt examples only within approved limits. [source: NCTSN fact sheet 2021; HomVEE ABC-Infant]
  • Fidelity through video supervision. Coaches code their own commenting and are supervised on recorded sessions. Practical meaning: record every session and regularly self-code 5-minute segments, even after certification. [source: NCTSN training guidelines]

4. Intervention inventory

This inventory has two parts. Methods 4.1–4.5 run through every session. Modules 4.6–4.11 are the session-specific target modules. 4.12 covers the coach's own fidelity practice.

The restricted session manual sets the exact activities, sample language, materials and critical adherence items for each session, and it is not drawn on. So the steps below give the published structure, with the coach-level detail in my own words and marked [synthesis] where no source describes it. Example language is illustrative unless quoted and cited. [source: NCTSN training guidelines]

4.1 In-the-moment (ITM) commenting — the core technique

  • Purpose / when: The developers call this the most crucial element. Use it continuously in every session, whenever the parent shows, or misses, a target behaviour: nurturance, following the lead, delight, or non-frightening behaviour. Comments highlight chances to nurture and respond to cues as they happen. [source: NCTSN fact sheet 2021; ClinicalTrials.gov NCT05096611 protocol; Haggerty 2015 thesis abstract]
  • Steps:
    1. Watch the dyad continuously. Look for a trigger: the child signals (cries, reaches, looks, offers a toy, turns away) and the parent responds or misses the cue. [source: NCTSN training guidelines, on "comment triggers"; detail synthesis]
    2. Comment within seconds, briefly and specifically. Build the comment from up to three components [source: Dozier Penn State slides; Dozier slides, Sweden]:
      • (a) Describe the parent's behaviour.
      • (b) Link it to the target.
      • (c) Link it to an outcome for the child.
    3. Keep comments on target. Comment on the ABC targets, not on general development or unrelated topics, because on-target percentage is a fidelity metric. [source: NCTSN training guidelines]
    4. Comment often. Training material gives roughly one comment per minute, each with at least one component, as a certification marker. Count missed opportunities as well. [source: Dozier slides, Sweden; NCTSN training guidelines]
    5. Make most comments positive. When the parent misses or contradicts a target, use a brief redirecting comment that points to what the child needs, then comment positively as soon as the parent adjusts. The sources say ITM comments "encourage or redirect" parent behaviour. [source: Haggerty 2015 thesis abstract; ClinicalTrials.gov NCT05096611 protocol; balance synthesis]
    6. Keep commenting during the manual discussion and video review, not only during play. Comments are interspersed throughout the session. [source: ClinicalTrials.gov NCT05096611 protocol]
  • Example language:
    • From the developers' slides: describe, "He's crying and you're holding him"; link to target, "Good job nurturing him"; link to outcome, "That lets him know you're there for him." [source: Dozier slides, Sweden]
    • Following the lead (illustrative): "She handed you the block and you took it and smiled. You're following her lead, and that tells her she can make things happen."
    • Redirect (illustrative): "Look, he's reaching toward you. Can you pick him up?"
  • Watch for:
    • Vague praise ("good job") with no description.
    • Comments that lecture or come too late to connect with the behaviour.
    • Long runs with no comments.
    • A redirect-heavy ratio.
    • Signs it is working: across sessions the parent picks up cues faster, starts naming their own behaviour, and needs fewer redirects. More frequent on-target and multi-component comments predicted gains in following the lead and reductions in intrusiveness (Caron et al., 2018, as reported in the developer slides). [source: Dozier Penn State slides]

4.2 Video feedback

  • Purpose / when: Lets the parent see their own interactions and recognise and celebrate successes. Used in every session. [source: Social Work Today 2017; HomVEE ABC-Infant; NCTSN fact sheet 2021]
  • Steps:
    1. Record the session.
    2. Choose short clips showing the parent doing the target well. Use clips from earlier sessions, or play back a segment from the current session during or after it. [source: Social Work Today 2017; ClinicalTrials.gov NCT05096611 protocol]
    3. Show the programme's standard example clips of the target behaviour where the manual calls for them. [source: ClinicalTrials.gov NCT05096611 protocol]
    4. As the clip plays, comment on it in the same three-component form as live comments [synthesis].
    5. Ask the parent what they notice in the child's response.
    6. Use clips across weeks to show progress. [source: HomVEE ABC-Infant, "highlighting strengths and celebrating progress"; steps 4–5 synthesis]
  • Example language (illustrative):
    • "Let's watch this bit from last week. See how she looks up at you when you start laughing with her?"
    • "What do you think she was feeling there?"
  • Watch for:
    • Parents who find watching themselves exposing. Start with clearly positive clips, and avoid showing clips of frightening behaviour without preparation [synthesis].
    • Get consent for recording and explain that recordings are used for supervision. [synthesis; recording for supervision per NCTSN training guidelines]

4.3 Manual-guided discussion of the week's target

  • Purpose / when: Each session introduces or revisits one target, explaining why it matters for children who have faced adversity. Used in every session. [source: ClinicalTrials.gov NCT05096611 protocol; Social Work Today 2017]
  • Steps [synthesis within manual structure]:
    1. Briefly link to last week's target.
    2. Present the week's target and its rationale in plain language:
      • children may push away;
      • children rely on the caregiver to help their body and behaviour settle;
      • following the lead supports self-control;
      • frightening behaviour disrupts regulation.
    3. Ask for the parent's own examples from the week.
    4. Go through the manual's critical content items, which are checked for adherence.
    5. Move to practice quickly.
  • Example language (illustrative): "Kids who've been through a lot sometimes act like they don't need us when they're upset. Our job is to comfort them anyway, so over time they learn they can count on us."
  • Watch for:
    • Discussion swallowing the session. ABC is practice-based, so keep talk short and the child present.
    • Content that sounds like blaming the parent. Frame it around the child's needs. [synthesis]

4.4 Structured play-based practice activities

  • Purpose / when: Creates the interactions in which the parent practises the targets and the coach comments. Used in every session. [source: ClinicalTrials.gov NCT05096611 protocol; Social Work Today 2017]
  • Steps:
    1. Set up the developmentally appropriate activity specified in the manual for that session, using toys the coach brings. [source: NCTSN fact sheet 2021, which lists toys as equipment; specific activities are in the manual, so [uncertain]]
    2. Tell the parent which target to practise.
    3. Step back and comment in the moment.
    4. Afterwards, reflect briefly on what the child seemed to need. The sources describe reflective discussion of children's developmental needs. [source: Social Work Today 2017; steps 2–3 synthesis]
  • Example language (illustrative): "For the next few minutes, just let him decide what to do with these toys, and see if you can go along with whatever he picks."
  • Watch for:
    • Activities that turn into teaching (naming colours, testing) instead of following.
    • A child who is asleep, ill or absent. Practice needs the dyad together. [synthesis]

4.5 Homework: daily observations

  • Purpose / when: Extends practice and noticing into daily life. Given and reviewed every session. [source: NCTSN training guidelines; NCTSN fact sheet 2021; ClinicalTrials.gov NCT05096611 protocol]
  • Steps [synthesis]:
    1. At the end of the session, agree what to observe during the week. For example: times the child was distressed and what the parent did, times the parent followed the lead, or moments the parent noticed an urge to react harshly.
    2. Give the manual's handout. Handouts exist in several languages. [source: NCTSN fact sheet 2021]
    3. At the next session, review the observations first. Praise any noticing, and comment on how the parent's actions matched the target.
  • Example language (illustrative): "This week, whenever she gets upset, just jot down or remember what happened and what you did. We'll go over it together next time."
  • Watch for: Low literacy or a busy household. Accept verbal recall, a phone note or a photo of a tick sheet. Treat any observation as success. [synthesis]

4.6 Nurturance module (sessions 1–2)

  • Purpose / when: Helps the parent comfort the child when the child is distressed, even when the child does not elicit it or pushes away, and even when nurturing does not come naturally. [source: HomVEE ABC-Infant; NHS Scotland EIF; Dozier slides, Sweden]
  • Steps:
    1. Explain that children who have faced adversity may push away, turn away or be hard to soothe. Caregivers may respond in kind, or respond to distress in ways that tell the child not to bring it to them: dismissing, fussing, distracting or ignoring. [source: Dozier slides, Sweden; NHS Scotland EIF]
    2. Help the parent reinterpret the child's cues. Pushing away or seeming self-sufficient can still mean the child needs comfort. [source: NHS Scotland EIF]
    3. Comment in the moment on every instance of distress and comfort: picking up, holding, soothing voice, staying close. [source: NCTSN fact sheet 2021; specifics synthesis]
    4. When the parent dismisses or distracts, redirect gently toward comforting, then comment positively as soon as they do. [synthesis]
  • Example language:
    • "He's crying and you're holding him" [source: Dozier slides, Sweden].
    • Illustrative: "She pulled away a little, but you stayed close and kept rubbing her back. That's nurturing even when she isn't asking for it."
  • Watch for:
    • Foster or adoptive parents who read rejection as "she doesn't like me".
    • Parents who fear spoiling the child.
    • Signs it is working: the parent moves toward the child at distress without prompting, and the child begins to approach the parent when upset. [synthesis]

4.7 Following the lead with delight (sessions 3–4; in Early Childhood, plus avoiding control struggles)

  • Purpose / when: Helps the parent respond to the child's signals and interests in play, without directing or taking over, and with visible enjoyment. This supports the child's self-regulation and sense of agency. In the toddler version it also avoids power struggles. [source: HomVEE ABC-Infant; HomVEE ABC-Early Childhood; Dozier Penn State slides]
  • Steps:
    1. Explain the rationale. Parents who follow the lead have children with better self-regulation. It resembles serve-and-return interaction. [source: Dozier slides, Sweden; Dozier Penn State slides]
    2. Set up play. Ask the parent to let the child choose and to respond to what the child does: imitate, describe, hand things, react with pleasure. [synthesis]
    3. Comment in the moment on each instance of following and of delight. Delight is coded and commented on in its own right. [source: Haggerty 2015 thesis abstract; specifics synthesis]
    4. Redirect when the parent leads, teaches, quizzes or takes the toy. [synthesis]
    5. Toddler version: help the parent sidestep control struggles over non-essential issues. [source: HomVEE ABC-Early Childhood names the target; method synthesis]
  • Example language:
    • Developer slide wording for an outcome link: following her lead is "going to make her feel important". [source: Dozier slides, Sweden]
    • Illustrative: "He started banging the cup and you banged yours too, and you're both laughing. That's following his lead with delight."
  • Watch for:
    • Parents who feel that following means "letting the child rule". Explain that this is time-limited play, not the whole of discipline. [synthesis]
    • Over-stimulating delight that becomes overwhelming. [synthesis]
    • Signs it is working: fewer parent-initiated changes of activity, and more shared affect. [synthesis]

4.8 Noticing signals and reducing overwhelming or frightening behaviour (ABC-Infant sessions 5–6)

  • Purpose / when: Helps the parent recognise and reduce intrusive, harsh, overwhelming or frightening behaviours, which undermine the child's behavioural and biological regulation and are linked to disorganised attachment. Examples are glaring, rough handling and threats. It also sharpens the parent's reading of the child's signals, for instance that the child needs a break. [source: HomVEE ABC-Infant; Dozier Penn State slides; Social Work Today 2017]
  • Steps:
    1. Present the rationale without shaming. Many parents do these things without realising how they affect a young child. [synthesis]
    2. Use the programme's example clips to show what frightening and intrusive behaviour looks like. [source: ClinicalTrials.gov NCT05096611 protocol, which mentions standard clips; content of clips not seen, [uncertain]]
    3. Help the parent identify their own versions. Possible ones include a loud voice, looming, teasing, tickling past the child's limit, rough play, angry faces and threats. [examples beyond glaring, rough handling and threats are synthesis]
    4. Practise reading the child's "too much" signals, such as gaze aversion, arching, whimpering or freezing, and backing off. [synthesis]
    5. Comment positively when the parent softens their voice or face, slows down, or gives space. [synthesis]
  • Example language (illustrative):
    • "She just looked away. You noticed and gave her a little space. That helps her feel safe with you."
    • "That tickling was fun at first. Now she's turning away, so let's see what happens if you pause."
  • Watch for:
    • Defensiveness or shame.
    • Disclosure of harsh discipline. Follow safeguarding procedures (see Section 5).
    • Parents whose frightening behaviour comes from their own trauma states, such as dissociation or sudden anger. Consider referral alongside ABC. [synthesis]

4.9 Calming the dysregulated child (ABC-Early Childhood sessions 5–6)

  • Purpose / when: Toddler version only. Helps the parent use calming strategies and stay physically and mentally present while the child is dysregulated, acting as co-regulator. [source: HomVEE ABC-Early Childhood; NHS Scotland EIF]
  • Steps [synthesis; the manual's specific calming strategies [uncertain]]:
    1. Explain that tantrums and meltdowns are times when the child cannot yet regulate alone.
    2. Help the parent stay near and calm rather than leaving, punishing or matching the child's intensity.
    3. Practise the parent's own calming: slow breathing, lowered voice.
    4. Comment in the moment on staying present and on any calming the parent offers.
    5. Debrief what helped.
  • Example language (illustrative): "He's really upset, and you're staying right next to him and keeping your voice soft. You're helping his body calm down."
  • Watch for:
    • Parent overwhelm. Coach the parent's self-regulation first.
    • Unsafe behaviour by the child. Safety comes before staying close.

4.10 "Voices from the past": recognising and overriding automatic responses (sessions 7–8)

  • Purpose / when: Helps the parent identify how their own experiences of being parented shape automatic responses that interfere with nurturing, following the lead, or (in Early Childhood) calming, and practise overriding them. [source: HomVEE ABC-Infant; HomVEE ABC-Early Childhood; Social Work Today 2017]
  • Steps:
    1. Introduce the idea that everyone carries messages from how they were raised, and that these can show up automatically with one's own child. [source: Social Work Today 2017, defining "voices from the past"; wording synthesis]
    2. Invite the parent to name situations where a target felt hard, using their homework observations and the video. [synthesis]
    3. Explore what they heard or experienced growing up in similar moments. Keep the focus on the link to present behaviour, not on processing trauma. [synthesis]
    4. Identify the automatic response and an alternative that matches the target. [synthesis]
    5. Practise noticing the urge and choosing the alternative in session, with in-the-moment comments when they do. [source: HomVEE ABC-Infant names "override automatic responses"; procedure synthesis]
  • Example language (illustrative):
    • "When he cries and you feel that pull to tell him to stop, whose voice does that sound like?"
    • "You noticed the urge and picked him up anyway. That's overriding it."
  • Watch for:
    • Distress, intrusive memories or dissociation in a parent with a trauma history. Slow down, ground the parent, and offer referral for their own therapy.
    • Parents who idealise their upbringing. Stay with the concrete behaviour rather than arguing. [synthesis]

4.11 Consolidation and celebration (sessions 9–10)

  • Purpose / when: Reinforces learning across all targets, gives extra practice, and celebrates progress before ending. [source: HomVEE ABC-Infant; HomVEE ABC-Early Childhood]
  • Steps [synthesis within the published goal]:
    1. Review each target and the parent's own examples.
    2. Run practice activities with in-the-moment comments on all targets.
    3. Show a selection of video clips of the parent's best moments across the 10 weeks to mark progress.
    4. Discuss situations that may be hard after ABC ends and how the parent will handle them.
    5. Close the case and link the family to other services as needed.
  • Example language (illustrative): "Look at this clip from week two and this one from today. Look how quickly you're going to him now when he's upset."
  • Watch for: Ending anxiety, especially in parents with loss histories. Name the ending early, and plan referrals if needs remain. [synthesis]

4.12 Coach fidelity practice: self-coding and supervision preparation

  • Purpose / when: Keeps commenting quality up. It is required during the trainee period and strongly recommended afterwards. [source: NCTSN training guidelines]
  • Steps:
    1. Upload session video weekly.
    2. Before in-the-moment supervision, code a 5-minute segment. Mark comment triggers, the comments made, the components in each, whether each was on target, and missed opportunities. [source: NCTSN training guidelines; HomVEE ABC-Infant]
    3. Calculate comments per minute and percentage on target. [source: NCTSN training guidelines]
    4. Bring clinical challenges, such as maternal depression or substance use, to group clinical supervision. [source: HomVEE ABC-Infant]
    5. After certification, keep a self-coding or peer-coding plan, and recertify every 2 years. [source: NCTSN training guidelines; HomVEE ABC-Infant]
  • Watch for: Drift into general chat or generic praise, falling comment rates, and a growing share of missed opportunities. [source: NCTSN training guidelines, which lists these metrics]

5. Handling problems

The sources say little about problem-handling. They name the following:

  • the narrow focus, so families with complex needs (concrete services, mental health, substance use) may need additional intervention [source: Social Work Today 2017];
  • clinical supervision covering maternal depression and substance use [source: HomVEE ABC-Infant];
  • ABC+D for maternal depression [source: ClinicalTrials.gov NCT05096611 protocol];
  • the requirement that the primary caregiver attend all 10 sessions [source: NCTSN training guidelines].

Everything else below is my own synthesis [synthesis]. Take it to ABC clinical supervision, which is the developer-sanctioned route for case problems.

  • Parent feels criticised by frequent comments:
    • Explain in session 1 that you will comment a lot and that most comments point out what is going well.
    • Keep the ratio strongly positive.
    • Cut redirects to a minimum and follow each one with a positive comment as soon as possible.
    • Ask at the end of each session how the comments felt.
  • Parent passive or "performing" for the camera:
    • Normalise being recorded.
    • Start with low-demand activities.
    • Comment on small, genuine moments rather than staged ones.
    • Use the video to show real successes.
  • Child asleep, ill or absent; chaotic household:
    • Practice needs the dyad together, so agree visit times around naps.
    • If the child is asleep, do the discussion and video parts, then practise when the child wakes, or reschedule.
    • Ask for the TV off and a play space, framed as "so I can catch the good moments".
    • Include other household members who are there, commenting on their interactions too. Anyone in the home may take part [source: Social Work Today 2017].
  • Non-adherence to homework:
    • Shrink the task to one observation, and accept verbal recall.
    • Start each session by asking about any moment the parent noticed, and praise it.
    • Never let homework review turn punitive.
  • Missed sessions:
    • Because all 10 sessions are needed, reschedule within the week rather than skip content.
    • Problem-solve barriers such as transport, shifts and shelter moves.
    • Offer virtual or hybrid delivery where allowed [source: HomVEE ABC-Infant].
  • Child pushes away; parent feels rejected (often in foster and adoptive care):
    • Go back to the nurturance rationale: the child's rejection is a learned strategy, and the parent's persistence is the intervention.
    • Comment on every attempt to comfort, whatever the child's response.
    • Track small changes on video, such as a child who now looks toward the parent when upset.
  • Parent resists "following the lead" ("they'll be spoiled", cultural norms of adult direction):
    • Explore the family's beliefs.
    • Frame following the lead as a few minutes of play a day that builds the child's self-control, not a whole parenting style.
    • Use the family's own language and examples, within approved adaptation limits [source: HomVEE ABC-Infant].
  • Defensiveness about frightening behaviour (sessions 5–6):
    • Avoid labelling the parent as scary.
    • Talk about how a small child experiences big faces and voices.
    • Use the programme's example clips before the parent's own clips.
    • Praise any softening.
  • Overwhelm or distress in "voices from the past" (sessions 7–8):
    • Watch for tearfulness, shutdown, dissociation or anger.
    • Slow down, ground the parent in the present and the child in front of them, and limit how much history is explored.
    • Return to the behavioural override.
    • Offer referral to individual trauma-focused therapy for the parent, run in parallel rather than inside ABC.
  • Parental depression, substance use, intimate partner violence:
    • Screen at intake and throughout.
    • Coordinate with treating services.
    • Consider ABC+D where available for depression [source: ClinicalTrials.gov NCT05096611 protocol].
    • Bring these issues to clinical supervision [source: HomVEE ABC-Infant].
    • If a parent is intoxicated or acutely unwell at a visit, end the session safely and reschedule.
  • Child-protection concerns:
    • If you observe or hear about maltreatment, follow your agency's and jurisdiction's mandatory reporting procedures.
    • Tell the parent at the outset that this limit on confidentiality exists.
    • Where possible, keep working with the family after a report.
  • Parent suicidality or self-harm:
    • Use your service's standard risk assessment and safety-planning protocol.
    • Include lethal-means counselling (safe storage or removal).
    • Pause ABC content while you do this.
  • Rupture with the coach (the parent becomes cool, cancels or argues):
    • Name it and ask what felt wrong.
    • Own any comment that landed badly.
    • Increase positive and strength-based comments.
    • Review a celebratory clip together.
  • Coach-side difficulties (low comment rate, generic praise, comments drifting off target, many missed opportunities):
    • Self-code a 5-minute segment weekly.
    • Before each session, plan which target triggers to watch for.
    • Rehearse three-component comments.
    • Raise drift in in-the-moment supervision [source: NCTSN training guidelines].
  • Telehealth problems:
    • Ask for a camera position that shows both partners' faces.
    • Agree a backup phone link.
    • Expect a short delay before your comments arrive, and keep them very brief.
    • Telehealth was used during COVID-19, with comparable gains in sensitivity [source: NCTSN fact sheet 2021].
  • Ending with ongoing needs:
    • Plan referrals before session 9.
    • ABC is brief by design and does not replace concrete, mental-health or substance-use services [source: Social Work Today 2017].
