Not a treatment recommendation
CEBC rates CPP 1 for infant and early-childhood mental health, and 2 for child/adolescent trauma and domestic-violence services. These are topic-specific registry ratings, not clinical guideline recommendations.
Scope: Children aged 0–5 who have experienced trauma and their caregivers.
- Children’s attachment (NG26)
Discussed in the source
NICE says to consider parent–child psychotherapy based on the Cicchetti and Toth model. This specified model should not be assumed equivalent to every intervention called CPP.
Scope: Preschool attachment difficulties where parents have maltreated or are at risk of maltreating their child; safeguarding concerns must be addressed.

Condition-specific assessments
Each conclusion applies to the population and use described. These source-based assessments do not certify the full entry or replace expert clinical review.
Attachment & Relational Patterns
Population and scope: Infants from maltreating families (about 13 months old at entry and 38 months at follow-up) and their biological mothers; the tested home-based CPP model, with child attachment security directly measured.
Randomized studies
A randomized study followed infants from maltreating families who were assigned to home-based CPP, psychoeducational parenting work or community services. Stronach et al. (2013), following the Cicchetti et al. (2006) cohort, identify CPP with the Lieberman and Van Horn model. At one year after treatment, analyses retaining original assignments among available follow-up participants favored CPP for secure attachment. Differences in attachment disorganization and parent-reported child behavior were not significant in those analyses. Treatment refusal, missing follow-up data and specialist delivery limit confidence and generalization. NICE NG26 separately says to consider the specified Cicchetti/Toth parent–child model for the preschool maltreatment subgroup, with safeguarding addressed. This assessment does not cover adult attachment styles, diagnosed attachment disorders or every CPP format.

How they work
Child-Parent Psychotherapy
Core mechanism: Within the safety of the therapeutic relationship, the therapist helps the parent recognize how their own history (ghosts) distorts perception of the child, while strengthening protective relational patterns (angels): healing happens in the dyad
Ontology: Young children's trauma symptoms are inseparable from the caregiving relationship: the dyad, not the individual child, is the unit of treatment; parental ghosts perpetuate intergenerational transmission
Circle of Security
Core mechanism: Helping caregivers recognize and regulate their own triggered defensive responses (shark music) so they can remain present to their child's actual attachment needs on the Circle of Security: providing safe haven when the child needs comfort and secure base when the child needs to explore
Ontology: Child security develops through repeated experience of a caregiver who is bigger, stronger, wiser, and kind: present enough to provide safe haven and secure base, and capable of reflecting on their own triggered responses without being controlled by them.

What each assumes — and misses
Child-Parent Psychotherapy
Philosophical roots: Bowlby (attachment as survival system); Fraiberg (ghosts in the nursery: the founding metaphor); Winnicott (good-enough mothering, holding environment); object relations; Stern (intersubjective world of the infant)
Blind spots: Caregiver participation and service resources can limit access. Duration varies with safety needs, system involvement and trauma complexity; CEBC reports an average range of 20–32 sessions.
Therapeutic voice: When he clings to you like that, what does it remind you of from your own childhood?
Circle of Security
Philosophical roots: Bowlby (attachment theory, safe haven and secure base); Ainsworth (Strange Situation, attachment patterns); Main (Adult Attachment Interview, reflective function); Winnicott (good enough mothering); Stern (attunement, intersubjectivity)
Blind spots: COS-P group protocol relies on DVD-based delivery which limits individualization; home visiting version requires significant training and supervision; not appropriate for active child abuse situations without additional safety planning; caregiver's own attachment trauma may require individual therapy beyond what COS provides
Therapeutic voice: Your child reached for you just then, and you pulled back. What were you feeling right at that moment? Not what you thought. What you felt.
Choosing between them
Child-Parent Psychotherapy (Attachment) and Circle of Security (Family Systems) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
